Abstract

A switch wire-connection terminal block structure includes a casing and at least one contact terminal. The contact terminal has a locking hole in direct communication with a receiving hole. The receiving hole communicates with a wire socket. A locking member is disposed in the receiving hole and lockable in the locking hole. A gasket member is fitted on the locking member. A guide channel is formed on inner wall of the receiving hole and extends in a locking direction of the locking member. The gasket member has a guide section extending in a direction reverse to the locking direction of the locking member. The guide section is slidably disposed in the guide channel. The receiving hole provides a larger locking travel for the locking member so that the terminal block is applicable to closed wire terminal.

First claim

What is claimed is:

1. A switch wire-connection terminal block structure comprising a casing, at least one contact terminal being disposed in the casing, the contact terminal having a locking hole, the locking hole being positioned at one end of a receiving hole in the casing, the receiving hole intersecting and communicating with a wire socket formed in the casing, a locking member being disposed in the receiving hole for locking into the locking hole, a gasket member being fitted on the locking member, at least one guide channel being formed on inner wall of the receiving hole, the guide channel extending in a direction reverse to a direction in which the locking member is locked into the locking hole, at least one guide section being formed on the gasket member, the guide section extending in the direction reverse to the direction in which the locking member is locked into the locking hole, the guide section being slidably disposed in the guide channel;
wherein the gasket member has at least one push section, the push section extending from the gasket member in a radial direction of the receiving hole away from the receiving hole, an elastic member being disposed beside the receiving hole for driving the push section in the direction reverse to the direction in which the locking member is locked into the locking hole.

2. The switch wire-connection terminal block structure as claimed in claim 1 , wherein a pushbutton is movably disposed on the casing, the pushbutton extending from outer side into the casing, an electro-conductive member being disposed in the casing and connected with the pushbutton, two ends of the contact terminal respectively having the locking hole and a contact section corresponding to the electro-conductive member, the electro-conductive member being drivable by the pushbutton to separably contact the contact section.

3. The switch wire-connection terminal block structure as claimed in claim 1 , wherein an interior of the casing is partitioned to form a lateral cavity for receiving the elastic member, the lateral cavity communicating with the inner wall of the receiving hole via a travel channel, the travel channel extending in the direction in which the locking member is locked into the locking hole, the push section extending from the travel channel into the lateral cavity to be driven by the elastic member, the travel channel guiding the push section to drive the gasket member to reciprocally move within the receiving hole along the path in which the locking member is locked into the locking hole.

4. The switch wire-connection terminal block structure as claimed in claim 3 , wherein a stop section is disposed between the receiving hole and the travel channel in the casing, the push section having a bent form to round the stop section and extend into the travel channel.

5. The switch wire-connection terminal block structure as claimed in claim 3 , wherein a pushbutton is movably disposed on the casing, the pushbutton extending from outer side into the casing, an electro-conductive member being disposed in the casing and connected with the pushbutton, two ends of the contact terminal respectively having the locking hole and a contact section corresponding to the electro-conductive member, the electro-conductive member being drivable by the pushbutton to separably contact the contact section, a spacer member is disposed between the contact section and the electro-conductive member and the elastic member, the spacer member defining the lateral cavity.

6. The switch wire-connection terminal block structure as claimed in claim 4 , wherein a pushbutton is movably disposed on the casing, the pushbutton extending from outer side into the casing, an electro-conductive member being disposed in the casing and connected with the pushbutton, two ends of the contact terminal respectively having the locking hole and a contact section corresponding to the electro-conductive member, the electro-conductive member being drivable by the pushbutton to separably contact the contact section, a spacer member is disposed between the contact section and the electro-conductive member and the elastic member, the spacer member defining the lateral cavity.

7. The switch wire-connection terminal block structure as claimed in claim 1 , wherein the guide channel is formed on the inner wall of the receiving hole, the guide section being disposed on a lateral edge of the gasket member corresponding to the guide channel.

8. The switch wire-connection terminal block structure as claimed in claim 3 , wherein the guide channel is formed on the inner wall of the receiving hole, the guide section being disposed on a lateral edge of the gasket member corresponding to the guide channel.

9. The switch wire-connection terminal block structure as claimed in claim 4 , wherein the guide channel is formed on the inner wall of the receiving hole, the guide section being disposed on a lateral edge of the gasket member corresponding to the guide channel.

10. The switch wire-connection terminal block structure as claimed in claim 5 , wherein the guide channel is formed on the inner wall of the receiving hole, the guide section being disposed on a lateral edge of the gasket member corresponding to the guide channel.

11. The switch wire-connection terminal block structure as claimed in claim 2 , wherein push paths of the contact section and the electro-conductive member are both not aligned with the position where the elastic member is positioned.

12. The switch wire-connection terminal block structure as claimed in claim 10 , wherein push paths of the contact section and the electro-conductive member are both not aligned with the position where the elastic member is positioned.

13. The switch wire-connection terminal block structure as claimed in claim 2 , wherein the casing has a front end, a rear end opposite to the front end and two lateral ends positioned on two sides of the front and rear ends, the pushbutton being disposed at the front end of the casing, a first contact terminal and a second contact terminal being positioned on two sides of the pushbutton, the electro-conductive member being positioned between the first and second contact terminals, the receiving hole communicating with the rear end of the casing, the wire socket communicating with the lateral ends.

14. The switch wire-connection terminal block structure as claimed in claim 10 , wherein the casing has a front end, a rear end opposite to the front end and two lateral ends positioned on two sides of the front and rear ends, the pushbutton being disposed at the front end of the casing, a first contact terminal and a second contact terminal being positioned on two sides of the pushbutton, the electro-conductive member being positioned between the first and second contact terminals, the receiving hole communicating with the rear end of the casing, the wire socket communicating with the lateral ends.

15. The switch wire-connection terminal block structure as claimed in claim 1 , wherein the locking member is a screw and the elastic member is a spring, the push section and guide section of the gasket member being both positioned beside a screw head of the screw.

16. The switch wire-connection terminal block structure as claimed in claim 7 , wherein the locking member is a screw and the elastic member is a spring, the push section and guide section of the gasket member being both positioned beside a screw head of the screw.
