Abstract

A wire connection terminal structure includes a case main body. Wire plug-in ports are connected with an electro-conductive module. Arcuate slide guide slots are disposed on the electro-conductive module. Rotary buttons are pivotally disposed in the case main body. Each rotary button has a movable section. A pin is disposed on the movable section. The pin is extended into the slide guide slot. At least one abutment leaf spring is pivotally disposed between the rotary button and the electro-conductive module. When a conductive wire passes through the wire plug-in port into the lateral side of the electro-conductive module, the rotary button can be driven to make the movable section gradually displace from a section of the abutment leaf spring near the pivotally rotational center to an outer lateral side. The abutment leaf spring is pushed to engage with the conductive wire.

First claim

What is claimed is:

1 . A wire connection terminal structure, comprising:
a case main body, wherein a recessed section and a wire plug-in port are formed on an inner surface of the case main body, and a first shaft rod is disposed in the recessed section of the case main body for extending axially with respect to an inner wall surface of said recessed section; an electro-conductive module connected with the wire plug-in port and being formed with a pair of substantially-parallel support sections, each of the support sections extends away from a base portion of the electro-conductive module, and at least one slide guide slot is completely formed on a corresponding wall surface of a respective one of the support sections to thereby be fully physically spaced from the inner wall surface of the recessed section of the case main body, wherein the at least one slide guide slot extends between two opposing closed ends; at least one rotary button pivotally disposed in the recessed section of the case main body via the first shaft rod, the at least one rotary button being formed with a shift section exposed to an outer side of the case main body and a movable section extending towards the base portion of the electro-conductive module, and a pin being disposed in the movable section and extending into the at least one slide guide slot for being freely movably guided thereby, wherein movement of the pin with respect to a corresponding one of the support sections is restricted by the opposing closed ends of the respective at least one slide guide slot; and at least one abutment leaf spring pivotally disposed between the at least one rotary button and the base portion of the electro-conductive module, and the at least one abutment leaf spring being driven by the at least one rotary button to pivotally rotate.

2 . The wire connection terminal structure as claimed in claim 1 , wherein two sets of symmetrical recessed sections and wire plug-in ports are formed on the inner surface of the case main body and the electro-conductive module is connected and disposed between the two wire plug-in ports, wherein lateral sockets are, respectively, formed on two lateral sides of the electro-conductive module and are, respectively, connected with the two wire plug-in ports for receiving two conductive wires plugged from the outer side of the case main body through a corresponding one of the two wire plug-in ports into the two recessed sections, wherein two rotary buttons are, respectively, symmetrically disposed in the two recessed sections and two abutment leaf springs are, respectively, symmetrically pivotally disposed between the two rotary buttons and the electro-conductive module, and wherein each of the two abutment leaf springs are drivable by a corresponding one of the two rotary buttons to pivotally rotate for pressing the two conductive wires against the electro-conductive module whereby the two conductive wires are electrically connected with each other via the electro-conductive module.

3 . The wire connection terminal structure as claimed in claim 1 , wherein an insertion socket is formed on the shift section of the at least one rotary button for a tool to be inserted therein, and wherein a holding channel is formed on the movable section of the at least one rotary button for holding the pin.

4 . The wire connection terminal structure as claimed in claim 3 , wherein a support rod and an insertion sink are disposed in the recessed section and an elastic member is pivotally fitted on the support rod for elastically abutting against the at least one rotary button and thereby the shift section protrudes out of the case main body, and wherein a hook section is disposed on the shift section, the hook section being receivable in the recessed section with the shift section for being engaged in the insertion sink.

5 . The wire connection terminal structure as claimed in claim 1 , wherein the at least one abutment leaf spring is pivotally disposed in the case main body via a second shaft rod serving as a pivotally rotational center for the at least one abutment leaf spring, and during rotation of the at least one rotary button for driving the at least one abutment leaf spring, the movable section of the at least one rotary button is gradually displaced from a section of the at least one abutment leaf spring adjacent the pivotally rotational center to an outer lateral side whereby an arm of operation force applied by the at least one rotary button to drive the at least one abutment leaf spring is gradually increased.

6 . The wire connection terminal structure as claimed in claim 5 , wherein a middle section of the at least one abutment leaf spring is formed with an arcuate bending section, and an inner side of the bending section being pivotally fitted on the second shaft rod whereby the at least one abutment leaf spring is pivotally rotatably assembled on the second shaft rod, and two ends of the bending section being, respectively, formed with a drive section in contact with the movable section of the at least one rotary button and an engagement section proximal to the electro-conductive module.

7 . The wire connection terminal structure as claimed in claim 6 , wherein the at least one abutment leaf spring includes multiple overlapped abutment leaf springs being formed with an identical bending configuration, and at least an outer end section of the engagement section of the at least one abutment leaf spring being formed with a forked structure.

8 . The wire connection terminal structure as claimed in claim 1 , wherein the electro-conductive module includes an electro-conductive plate and a lateral support disposed on a lateral side of the electro-conductive plate, and the lateral support being formed with a lateral socket connected with the wire plug-in port, wherein each of the support sections is disposed on a corresponding one of two sides of the lateral socket, thereby a corresponding one of the at least one slide guide slot is symmetrically formed on a respective one of the support sections.

9 . The wire connection terminal structure as claimed in claim 8 , wherein a perforation is formed on each of the support sections and a shaft rod socket is formed in the recessed section of the case main body, and wherein the first shaft rod passes through each perforation of the support sections and the rotary button for being inserted into the shaft rod socket to thereby extend axially with respect to the inner wall surface of said recessed section whereby the electro-conductive module, the at least one rotary button, and the at least one abutment leaf spring, are assemblable in the case main body.

10 . The wire connection terminal structure as claimed in claim 8 , wherein the electro-conductive plate and the lateral support of the electro-conductive module are integrally formed with respect to one another.

11 . The wire connection terminal structure as claimed in claim 8 , wherein an opening is formed through the lateral support for communication with the lateral socket, and wherein a lateral side of the electro-conductive plate is fitted in the opening whereby the lateral support is connected with the electro-conductive plate.

12 . The wire connection terminal structure as claimed in claim 1 , wherein the at least one slide guide slot is hollow and is formed with a closed arcuate configuration.

13 . The wire connection terminal structure as claimed in claim 12 , wherein two sets of symmetrical recessed sections and wire plug-in ports are formed on the inner surface of the case main body and the electro-conductive module is connected and disposed between the two wire plug-in por
