DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(27) Please refer to FIGS. 1 to 4. According to a first embodiment, the rail terminal assembling structure of the present invention includes a protection member 1, a conductive plate 2 and a metal leaf spring 3. The protection member 1 has a contact side section 11 and a connection side section 12 opposite to each other. Two lateral sections 13 are respectively disposed on two sides of the connection side section 12. The lateral sections 13 extend from the two sides of the connection side section 12 to connect with two sides of the contact side section 11 so as to define an assembling passage 14 passing through the protection member 1. One end of the assembling passage 14 is a wire inlet 141. At the junction between the connection side section 12 and each of the two lateral sections 13, the wire inlet 141 is formed with a first locating section 131, (such as a lateral notch). In addition, a second locating section 15 is disposed at one end of the protection member 1 distal from the first locating sections 131. Moreover, at least one elastic locating section 121 is disposed on the connection side section 12. The elastic locating section 121 protrudes toward the assembling passage 14.

(28) In a preferred embodiment, the second locating section 15 is a stop plate downward bent from an edge of the connection side section 12 toward the assembling passage 14. A perforation 151 is formed on one side of the stop plate proximal to the connection side section 12. The elastic locating section 121 is a protruding elastic locating tongue section formed by means of punching.

(29) One end of the conductive plate 2 extends into the assembling passage 14 of the protection member 1 and is securely attached to an inner surface of the contact side section 11. In a preferred embodiment, the conductive plate 2 is respectively formed with lateral recesses 22 near two lateral sides of two end sections. The lateral recesses 22 can be fitted with the portions of the two lateral sections 13 of the protection member 1 in adjacency to the contact side section 11 with the conductive plate 2 attached to the inner side of the contact side section 11. Accordingly, the protection member 1 is located and hindered from moving in the axial direction of the conductive plate 2. The conductive plate 2 has an inner face 23 distal from the contact side section 11. In addition, two end sections of the conductive plate 2 are respectively formed with arched edges 21 bent and extending in a direction away from the assembling passage 14.

(30) In practice, the conductive plate 2 not only can be secured by means of fitting the lateral recesses 22 with the protection member 1, but also can be securely connected with the protection member 1 by means of other suitable structures and manners. In this case, the conductive plate 2 can be better multidirectionally located.

(31) The metal leaf spring 3 has a first section 31, a second section 32 and an elastic bight section 33 connected between the first and second sections 31, 32. Accordingly, the metal leaf spring 3 is a substantially U-shaped member. Two first located sections 313 are respectively disposed on two sides of the first section 31 of the metal leaf spring 3 near the middle of the first section 31, (such as outward expanded lateral protrusion sections). The first section 31 is formed with a locating hole 312 corresponding to the elastic locating section 121.

(32) In a preferred embodiment, a second located section 311 (such as an end protrusion section) is disposed at a tail end of the first section 31 of the metal leaf spring 3. An elastic end section 321 is disposed at a tail end of the second section 32. The elastic end section 321 is arched and bent toward the contact side section 11.

(33) When assembled, after the conductive plate 2 is connected with the protection member 1, the metal leaf spring 3 is extended into the assembling passage 14 with the first section 31 attached to the connection side section 12. The second locating section 15 (the stop plate) serves to stop the tail end of the first section 31 of the metal leaf spring 3. At this time, the second located section 311 is inserted into the perforation 151, while the elastic locating section 121 (elastic locating tongue section) extends into the locating hole 312. Also, the two first located sections 313 are respectively snugly securely engaged with the two first locating sections 131. Accordingly, the first section 31 of the metal leaf spring 3 is securely connected with the connection side section 12 of the protection member 1 to effectively locate the metal leaf spring 3. Also, the elastic end section 321 of the second section 32 of the metal leaf spring 3 abuts against the inner face 23 of the conductive plate 2.

(34) In use, the external conductive wire A extends into the assembling passage 14 from one side near the first locating section 131. At this time, the conductive wire A first pushes the second section 32 of the metal leaf spring 3 to elastically compress and deform the elastic bight section 33. After the conductive wire A passes through the elastic end section 321, under the elastic restoring force of the elastic bight section 33, the elastic end section 321 of the second section 32 cooperates with the inner face 23 of the conductive plate 2 to together hold the conductive wire A and electrically connect therewith. In the case that the conductive wire A is pulled by an external force, the conductive wire A will drive the second section 32 to move in reverse direction. Under such circumstance, the second section 32 will gradually move toward the conductive wire A and fasten the conductive wire A to effectively hinder the conductive wire A from being loosened and extracted out.

(35) In the above structure of this embodiment, the first locating sections 131, the elastic locating section 121 (the elastic locating tongue section) and the perforation 151 of the second locating section 15 are connected with the first located sections 313, the locating hole 312 and the second located section 311. Accordingly, the first section 31 of the metal leaf spring 3 is located with the connection side section 12 of the protection member 1 at multiple portions. As shown in FIG. 4, when the conductive wire A is pulled by the external force, the first section 31 of the metal leaf spring 3 bears a clockwise torque. At this time, by means of the design that the second locating section 15 (such as the perforation 151) is fitted with the second located section 311, the force applied by the locating hole 312 to the elastic locating section 121 is effectively reduced. Therefore, the possibility of deformation of the elastic locating section 121 due to the force is minified. In this case, the conductive wire A can be more securely assembled with the terminal without easy loosening and detachment.

(36) Please now refer to FIGS. 5 to 7. According to a second embodiment, the rail terminal assembling structure of the present invention includes a protection member 1a, a metal leaf spring 3a and a conductive plate 2 identical to the conductive plate of the first embodiment. The protection member 1a has a contact side section 11a and a connection side section 12a opposite to each other. Two lateral sections 13a are respectively disposed on two sides of the connection side section 12a. The lateral sections 13a extend from the two sides of the connection side section 12a to connect with two sides of the contact side section 11a so as to define an assembling passage 14a passing through the protection member 1a. One end of the assembling passage 14a is a wire inlet 141a. A first locating section 131a, (such as a lateral notch) is formed at the junction between the connection side section 12a and each of the two lateral sections 13a. In addition, a second locating section 15a is disposed on one side of the protection member 1a distal from the first locating sections 131a. Moreover, an elastic locating section 121a is disposed on the connection side section 12a. The elastic locating section 121a protrudes toward the assembling passage 14a.

(37) In a preferred embodiment, the second locating section 15a is a stop plate downward bent from an edge of the connection side section 12a toward the assembling passage 14a. A middle section of the stop plate is punched to form an upward protruding elastic tongue section 151a obliquely protruding toward the connection side section 12a. A gap is reserved between the upward protruding elastic tongue section 151a and the connection side section 12a. The elastic locating section 121a is a protruding elastic locating tongue section formed by means of punching. In addition, two lateral stop sections 132a are respectively disposed on the two lateral sections 13a near an edge of the second locating section 15a (the stop plate). The lateral stop sections 132a are bent toward the assembling passage 14a. The two lateral stop sections 132a respectively abut against two lateral outer sides of the second locating section 15a (the stop plate).

(38) The conductive plate 2 is securely assembled and connected on the inner surface of the contact side section 11a of the protection member 1a in the same manner as the first embodiment.

(39) The metal leaf spring 3a has a first section 31a, a second section 32a and an elastic bight section 33a connected between the first and second sections 31a, 32a. Accordingly, the metal leaf spring 3a is a substantially U-shaped member. Two outward expanded first located sections 313a are respectively disposed on two sides of the first section 31a of the metal leaf spring 3a near the middle of the first section 31a, (such as lateral protrusion sections). The first section 31a is formed with a locating hole 312a corresponding to the elastic locating section 121a. An elastic end section 321a is disposed at a tail end of the second section 32a. The elastic end section 321a is arched and bent toward the contact side section 11a.

(40) When assembled, after the conductive plate 2 is connected with the protection member 1a, the metal leaf spring 3a is extended into the assembling passage 14a with the first section 31a attached to the connection side section 12a. The second locating section 15a (the stop plate) serves to stop the tail end of the first section 31a of the metal leaf spring 3a. The tail end of the first section 31a is directly inserted into the gap between the upward protruding elastic tongue section 151a and the connection side section 12a. In addition, the elastic locating section 121a (the elastic locating tongue section) is cooperatively extended into the locating hole 312a. The two first located sections 313a (the lateral protrusion sections) are respectively located in the two first locating sections 131a (the lateral notches). Accordingly, the first section 31a of the metal leaf spring 3a is securely connected with the connection side section 12a of the protection member 1a to locate the metal leaf spring 3a. Also, the elastic end section 321a of the second section 32a of the metal leaf spring 3a abuts against the inner face 23 of the conductive plate 2.

(41) In use, the external conductive wire A extends into the assembling passage 14a from one side near the first locating section 131a (the lateral notch). At this time, the conductive wire A first pushes the second section 32a of the metal leaf spring 3a to elastically compress and deform the elastic bight section 33a. After the conductive wire A passes through the elastic end section 321a, under the elastic restoring force of the elastic bight section 33a, the elastic end section 321a of the second section 32a cooperates with the inner face 23 of the conductive plate 2 to together hold the conductive wire A and electrically connect therewith. In the case that the conductive wire A is pulled by an external force, the conductive wire A will drive the second section 32a to move in reverse direction. Under such circumstance, the second section 32a will gradually move toward the conductive wire A and fasten the conductive wire A to effectively hinder the conductive wire A from being loosened and extracted out.

(42) Please now refer to FIGS. 8 to 10. According to a third embodiment, the rail terminal assembling structure of the present invention includes a protection member 1b and a conductive plate 2 and metal leaf spring 3a identical to the conductive plate and metal leaf spring of the second embodiment. The protection member 1b has a contact side section 11b and a connection side section 12b opposite to each other. Two lateral sections 13b are respectively disposed on two sides of the connection side section 12b. The lateral sections 13b extend from the two sides of the connection side section 12b to connect with two sides of the contact side section 11b so as to define an assembling passage 14b passing through the protection member 1b. One end of the assembling passage 14b is a wire inlet 141b. A first locating section 131b, (such as a lateral notch) is formed at the junction between the connection side section 12b and each of the two lateral sections 13b. In addition, a second locating section 15b is disposed on one side of the protection member 1b distal from the first locating sections 131b (the lateral notch).

(43) Moreover, an elastic locating section 121b is disposed on the connection side section 12b. The elastic locating section 121b protrudes toward the assembling passage 14b.

(44) In a preferred embodiment, the second locating section 15b is a bent plate extending into the assembling passage 14b and bent toward the first locating sections 131b (the lateral notch). In addition, two lateral stop sections 132b are respectively disposed on the two lateral sections 13b near an edge of the second locating section 15b (the bent plate). The lateral stop sections 132b are bent toward the assembling passage 14b. The two lateral stop sections 132b respectively abut against the bottom side of the second locating section 15b (the bent plate).

(45) The conductive plate 2 is securely assembled and connected on the inner surface of the contact side section 11b of the protection member 1b in the same manner as the first embodiment.

(46) When assembled, after the conductive plate 2 is connected with the protection member 1b, the metal leaf spring 3a is extended into the assembling passage 14b with the first section 31a attached to the connection side section 12b. The second locating section 15b (the bent plate) serves to hold the tail end of the first section 31a of the metal leaf spring 3a. In addition, the elastic locating section 121b (the elastic locating tongue section) is cooperatively extended into the locating hole 312a. The two first located sections 313a (the lateral protrusion sections) are respectively inserted in the two first locating sections 131b (the lateral notches). Accordingly, the first section 31a of the metal leaf spring 3a is securely connected with the connection side section 12b of the protection member 1b to locate the metal leaf spring 3a. Also, the elastic end section 321a of the second section 32a of the metal leaf spring 3a abuts against the inner face 23 of the conductive plate 2.

(47) In use, the external conductive wire A extends into the assembling passage 14b from one side near the first locating section 131b (the lateral notch). At this time, the conductive wire A first pushes the second section 32a of the metal leaf spring 3a to elastically compress and deform the elastic bight section 33a. After the conductive wire A passes through the elastic end section 321a, under the elastic restoring force of the elastic bight section 33a, the elastic end section 321a of the second section 32a cooperates with the inner face 23 of the conductive plate 2 to together hold the conductive wire A and electrically connect therewith. In the case that the conductive wire A is pulled by an external force, the conductive wire A will drive the second section 32a to move in reverse direction. Under such circumstance, the second section 32a will gradually move toward the conductive wire A and fasten the conductive wire A to effectively hinder the conductive wire A from being loosened and extracted out.

(48) Please now refer to FIGS. 11 to 13. According to a fourth embodiment, the rail terminal assembling structure of the present invention includes a protection member 1c and a conductive plate 2 and metal leaf spring 3a identical to the conductive plate and metal leaf spring of the second embodiment. The protection member 1c has a contact side section 11c and a connection side section 12c opposite to each other. Two lateral sections 13c are respectively disposed on two sides of the connection side section 12c. The lateral sections 13c extend from the two sides of the connection side section 12c to connect with two sides of the contact side section 11c so as to define an assembling passage 14c passing through the protection member 1c. One end of the assembling passage 14c is a wire inlet 141c. A first locating section 131c, (such as a lateral notch) is formed at the junction between the connection side section 12c and each of the two lateral sections 13c. In addition, two second locating sections 132c are disposed at one end of the protection member 1c distal from the first locating sections 131c (the lateral notch). Moreover, an elastic locating section 121c is disposed on the connection side section 12c. The elastic locating section 121c protrudes toward the assembling passage 14c.

(49) In a preferred embodiment, the second locating sections 132c are two lateral stop sections respectively disposed on an edge of each of the two lateral sections 13c distal from the first locating section 131c (the lateral notch). The lateral stop sections are bent toward the assembling passage 14c. In addition, a gap 15c is reserved between the second locating sections 132c (the lateral stop sections) and the connection side section 12c.

(50) The conductive plate 2 is securely assembled and connected on the inner surface of the contact side section 11c of the protection member 1c in the same manner as the first embodiment.

(51) When assembled, after the conductive plate 2 is connected with the protection member 1c, the metal leaf spring 3a is extended into the assembling passage 14c with the first section 31a attached to the connection side section 12c. The tail end of the first section 31a is directly passed through the gap 15c and the elastic locating section 121c (the elastic locating tongue section) is cooperatively extended into the locating hole 312a. The two first located sections 313a (the lateral protrusion sections) are respectively engaged in the two first locating sections 131c (the lateral notches). Accordingly, the first section 31a of the metal leaf spring 3a is securely connected with the connection side section 12c of the protection member 1c to locate the metal leaf spring 3a. Also, the elastic end section 321a of the second section 32a of the metal leaf spring 3a abuts against the inner face 23 of the conductive plate 2.

(52) In use, the external conductive wire A extends into the assembling passage 14c from one side near the first locating section 131c (the lateral notch). At this time, the conductive wire A first pushes the second section 32a of the metal leaf spring 3a to elastically compress and deform the elastic bight section 33a. After the conductive wire A passes through the elastic end section 321a, under the elastic restoring force of the elastic bight section 33a, the elastic end section 321a of the second section 32a cooperates with the inner face 23 of the conductive plate 2 to together hold the conductive wire A and electrically connect therewith. In the case that the conductive wire A is pulled by an external force, the conductive wire A will drive the second section 32a to move in reverse direction. Under such circumstance, the second section 32a will gradually move toward the conductive wire A and fasten the conductive wire A to effectively hinder the conductive wire A from being loosened and extracted out.

According to a seventh embodiment, the rail terminal assembling structure of the present invention includes a protection member 4 and a conductive plate 2 and metal leaf spring 3a identical to the conductive plate and metal leaf spring of the second embodiment. The protection member 4 has a contact side section 41 and a connection side section 42 opposite to each other. Two lateral sections 43 are respectively disposed on two sides of the connection side section 42. The lateral sections 43 extend from the two sides of the connection side section 42 to connect with two sides of the contact side section 41 so as to define an assembling passage 44 passing through the protection member 4. One end of the assembling passage 44 is a wire inlet 441.

(68) In conclusion, in the rail terminal assembling structure of the present invention, the protection member and the metal leaf spring can be truly conveniently assembled with each other and more securely located. This improves the shortcoming of the conventional terminal assembling structure that the conductive plate is needed to help in assembling the metal leaf spring with the protection member. Moreover, after the protection member is assembled with the conductive plate, the wire plug-in direction can be adjusted in accordance with the required different angles. (For example, the angle can be changed as shown by the phantom lines of FIG. 1). Therefore, the external conductive wire can be plugged into the terminal by different angles. Accordingly, the rail terminal assembling structure of the present invention is novel, advanced and inventive.
