Two lateral sides of the grounding member are connected in the case body for holding a preset grounding rail. The case body is formed with two lower sections respectively corresponding to two sides of the grounding member. A foot section extends from at least one of the two lower sections. A first connection side and a second connection side are disposed on two lateral sides of the foot section. The first and second connection sides are connected with an outer sidewall of the lower section to form a socket with an open top side. A tool can be extended into the socket to pull and extend the foot section. Via the lower section, the grounding member is driven to detach from the grounding rail or hold the grounding rail.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] Please refer to FIGS. 3 to 7. The rail holding structure of the rail terminal of the present invention mainly includes a case body 1 and a grounding member 2.

[0019] The surface of the case body 1 is formed with a recess 11 for receiving the grounding member 2 and multiple wire plug-in sockets 17 and operation holes 18. The wire plug-in sockets 17 are for conductive wires to plug in. A push member (not shown) is disposed in the operation hole 18. A tool B can be extended into the operation hole 18 to operate the push member so as to drive an internal conductive component (not shown) and help in connecting the conductive wire plugged in the wire plug-in socket 17 with the grounding member 2 or disconnecting the conductive wire from the grounding member 2. The case body 1 is respectively formed with two lower sections 12, 13 in adjacency to two lateral sides of the recess 11. A cavity 14 is at least formed in the lower section 12 (or the lower section 13). A hook-like foot section 15 outward extends from a lateral side of the lower section 12 (or the lower section 13). A first connection side 161 and a second connection side 162 are respectively disposed on two lateral sides of the foot section 15. The first and second connection sides 161, 162 are respectively connected with an outer sidewall 121 of the lower section 12. The first and second connection sides 161, 162 and the outer sidewall 121 and the foot section 15 define therebetween a socket 16 with an open top side. In addition, a projection area of the first connection side 161 in a transverse direction of the socket 16 and a projection area of the second connection side 162 in the transverse direction of the socket 16 are staggered. By means of such design, the demolding operation of plastic injection in manufacturing process can be conveniently performed.

[0020] In a preferred embodiment, the inner sides of the first and second connection sides 161, 162 are respectively formed with a first guide section 1614 and a second guide section 1623 in adjacency to the opening of the socket 16. (The first and second guide sections 1614, 1623 can be downward obliquely cut plane faces). The first and second guide sections 1614, 1623 serve to guide the tool B to successfully slide from outer side into the socket 16. In addition, the first connection side 161 has at least one set of first connection section 1611 and first hollow section 1612, which are alternately arranged. The second connection side 162 has at least one second connection section 1621 corresponding to the first hollow section 1612. The second connection section 1621 has a configuration and a size identical to the configuration and the size of the first hollow section 1612. Accordingly, the projection area of the first connection side 161 in the transverse direction of the socket 16 and the projection area of the second connection side 162 in the transverse direction of the socket 16 are staggered.

[0021] In application of the above structure, as necessary, the first connection side 161 can alternatively have multiple sets of first connection sections 1611 and first hollow sections 1612, which are alternately arranged. The second connection side 162 has multiple second connection sections 1621 respectively corresponding to the first hollow sections 1612. The second connection sections 1621 respectively have a configuration and a size identical to the configuration and the size of the first hollow sections 1612. Accordingly, the projection area of the first connection side 161 in the transverse direction of the socket 16 and the projection area of the second connection side 162 in the transverse direction of the socket 16 are staggered as a structural feature of the present invention.

[0022] An elastic first section 21 and an elastic second section 22 respectively extend from two lateral sides of the grounding member 2 to lateral sides of the two lower sections 12, 13. An elastic holding system is formed between the first and second sections 21, 22 for holding a preset grounding rail A. An extension end section of the first section 21 (or the second section 22) is formed with a hook-like tail section 23. The tail section 23 is inlaid in the cavity 14 of the lower section 12 (or the lower section 13), whereby the first section 21 (or the second section 22) can be elastically extended or retracted along with the move of the lower section 12 (or the lower section 13).

[0023] In practical application of the present invention, when the first and second sections 21, 22 of the grounding member 2 oppositely elastically hold the grounding rail A, the case body 1 is secured on the rail A with the grounding member 2. In addition, the conductive wires plugged in the respective wire plug-in sockets 17 are electrically connected with the grounding rail A. When the tool B (such as a flat-blade screwdriver) is extended into the socket 16, the first guide section 1614 or the second guide section 1623 serves to guide the tool B to successfully slide from outer side into the socket 16. Then, the tool B outward pulls and extends the foot section 15 to drive the lower section 12 (or the lower section 13). At this time, the first section 21 (or the second section 22) and the second section 22 (or the first section 21) are oppositely expanded, whereby the grounding member 2 can be detached from the grounding rail A.

[0024] In the above structure, the first and second connection sides 161, 162 serve as two lateral stoppers between the foot section 15 and the outer sidewall 121. Therefore, when the tool B (such as a flat-blade screwdriver) is extended into the socket 16 to outward pull and extend the foot section 15, the first and second connection sides 161, 162 enhance the structural strength of the periphery of the socket 16 to avoid twisting or deformation of the foot section 15. Also, the first and second connection sides 161, 162 prevent the tool B (such as a flat-blade screwdriver) from slipping out of the socket 16 during the force application process.

[0025] In conclusion, the rail holding structure of the rail terminal of the present invention can truly achieve the effects of enhancing the structural strength of the periphery of the socket and preventing the tool from slipping out of the socket in force application process. The rail holding structure of the rail terminal of the present invention is inventive and advanced.

[0026] 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.
