WIRE CONNECTION TERMINAL STRUCTURE

Abstract

A wire connection terminal structure includes a terminal main body and a stopper member. One end of the terminal main body is formed with a connection section. Two support legs extend from the connection section for securely connecting with a preset circuit board. The connection section defines a socket. An elastic abutment plate obliquely extends from the connection section between the two support legs. A locating section is disposed at one end of each support leg. The stopper member is securely connected to the support legs via the locating sections. A stop face is formed on one side of one end of the stopper member proximal to the connection section and positioned in the moving path of the elastic abutment plate when elastically deformed. After the elastic abutment plate is forced, the deformation amount of the elastic abutment plate is restricted by the stop face.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0031] Please refer to FIGS. 4 to 8. The wire connection terminal structure of the present invention includes a terminal main body 1 and a stopper member 3. The terminal main body 1 is made of a metal plate by means of punching and thereafter bending. One end of the terminal main body 1 is formed with a connection section 11. The terminal main body 1 further has at least one support leg 14 (there are two support legs 14 in the drawings) extending from the connection section 11 to the other end of the terminal main body 1. The connection section 11 defines a socket 12. In addition, the terminal main body 1 has an elastic abutment plate 13 obliquely extending from the connection section 11 into the socket 12 (between the two support legs 14 as shown in the drawings). An end section of each support leg 14 is formed with a connecting section 15 outward bent from the support leg 14. The connecting section 15 is connected (soldered) with a preset plane face (circuit board) or a wire connection section. In addition, a locating section 16 is disposed at one end of the support leg 14 proximal to the connecting section 15. The locating section 16 is a protrusion structure protruding to a lateral side of the elastic abutment plate 13.

[0032] The stopper member 3 is securely connected to the middle of the support leg 14 of the terminal main body via the locating section 16. In a preferred embodiment, each of two sides of the stopper member 3 is formed with a recess 311 corresponding to the locating section 16. In addition, a channel 31 is formed on one face of the stopper member 3 distal from the two support legs 14 in communication with the two recesses 311. The locating section 16 passes through the recess 311 and then transversely bends to extend into the channel 31, whereby the stopper member 3 is securely connected between the middles of the two support legs 14.

[0033] A stop face 32 is formed on one side of one end of the stopper member 3 proximal to the connection section 11 and directed to the socket 12. The stop face 32 is positioned in the moving path of the elastic abutment plate 13 when elastically deformed. In addition, a guide slope 33 is formed at the middle of one face of the stopper member 3, which faces the socket 12. The inclination direction of the guide slope 33 is approximately identical to the extending direction of the elastic abutment plate 13.

[0034] In a preferred embodiment, an insulation housing 2 is fitted around the terminal main body 1 as necessary. One end of the housing 2 is formed with a perforation 21 in alignment with the socket 12. Two lateral sides of the other end of the housing 2 are formed with lateral notches 22 for the support legs 14 to pass through and outward extend.

[0035] Please now refer to FIGS. 9 and 10. In actual application of the present invention, an external conductive wire 4 can be directly obliquely plugged through the perforation 21 into the socket 12 in a direction to the elastic abutment plate 13 inside the socket 12. At this time, the conductive wire 4 will push the elastic abutment plate 13 to a preset extent. Thereafter, the elastic abutment plate 13 is restricted by the stop face 32 of the stopper member 3 from being further deformed and biased. Accordingly, the deformation amount of the elastic abutment plate 13 will keep under the yield point without permanent deformation.

[0036] After the oblique conductive wire 4 passes through the elastic abutment plate 13, the conductive wire 4 will directly abut against the guide slope 33, whereby the guide slope 33 will guide the conductive wire 4 to further move downward to be located between the support legs 14 and the stopper member 3 and the terminal main body 1. At this time, the elastic abutment plate 13 will elastically restore to abut against the conductive wire 4 and tightly press the conductive wire 4 against the inner wall of the socket 12. Under such circumstance, the conductive wire 4 is securely held and located without easy loosening or detachment under external extraction force.

[0037] In the wire connection terminal structure of the present invention, the stopper member 3 is securely connected with the ends of the two support legs 14 distal from the connection section 11, (that is, proximal to the circuit board). Therefore, the stopper member 3 can enhance the structural strength between the two support legs 14. In this case, when the conductive wire 4 is plugged into the socket 12 to apply an action force to the connection section 11, the swinging and unstable condition of the two support legs 14 are reduced and improved.

[0038] Please now refer to FIG. 11, which shows a modified embodiment of the stopper member 3. In this embodiment, a (protruding) back section 34 is disposed on one face of the stopper member 3 distal from the two support legs 14. The back section 34 is positioned between the two recesses 311 and serves to enhance the frictional interference between the stopper member 3 and the housing 2. Under such circumstance, the terminal main body 1 and the housing 2 can be more securely assembled with each other.

[0039] In conclusion, the wire connection terminal structure of the present invention can truly prevent the elastic abutment plate from being over-deformed when the conductive wire is plugged in by an improper angle so that the conductive wire can be reliably and effectively located. The wire connection terminal structure of the present invention is inventive and advanced.

[0040] The above embodiments are only used to illustrate the present invention, not intended to limit the scope thereof. Many modifications of the above embodiments can be made without departing from the spirit of the present invention.
