DETAILED DESCRIPTION

[0021] The specific embodiments of the utility model are described in detail below with reference to the drawings, but it should be understood that the protection scope of the utility model is not limited by the specific embodiments.

[0022] The utility model is a wire terminal, which can conveniently connect or disconnect the wire 6 without tools such as screwdrivers, and the internal connection condition can be conveniently observed through the transparent material transparent plate 201, and the wire 6 in the test hole 2011 provided on the transparent plate 201 can be tested by a test pen to facilitate troubleshooting.

[0023] Referring to the drawings, a wiring terminal comprises a connecting base 1 and a shell 2, the connecting base 1 is provided with a clamping groove, the wiring terminal can be installed on a mounting plate, and a plurality of wiring terminals can be installed on the same mounting plate in parallel.

[0024] A first connecting rod 302 is installed on the shell 2, the first connecting rod 302 penetrates the shell 2, and the two sides of the first connecting rod 302 are in the same plane as the two sides of the shell 2, a cam 301 is fixedly connected to the first connecting rod 302, a clamping block 303 matched with the cam 301 is installed on the shell 2, a handle 3 is fixedly connected to the cam 301, and a through groove 204 is formed in the upper end surface of the shell 2 and matched with the handle 3.

[0025] The handle 3 can rotate the handle 3 and the cam 301, because the cam 301 and the clamping block 303 are matched with each other, when the handle 3 and the cam 301 are rotated to a specific position, the cam 301 will extrude the clamping block 303, and the clamping block 303 will limit the cam 301 through friction. The clamping block 303 is made of rubber, when the handle 3 is close to the vertical position of the upper end surface of the shell 2 and close to the parallel position of the upper end surface of the shell 2, the clamping block 303 limits the cam 301 through friction, the friction of the cam 301 extruding the clamping block 303 is sufficient to limit the cam 301, and the handle 3 fixedly connected to the cam 301 is also limited.

[0026] The handle 3 is connected with a spring 402, the spring 402 is a tensile spring, one side of the spring 402 is fixedly connected to the handle 3, and the other side is fixedly connected to a pressing plate assembly 4, the pressing plate assembly 4 is connected with a second connecting rod 401, the second connecting rod 401 is clamped in the shell 2, and the pressing plate assembly 4 can rotate around the second connecting rod 401. The pressing plate assembly 4 is provided with two metal plates with an included angle, the two metal plates are fixedly connected and the included angle is unchanged, the upper metal plate is used for contacting the handle 3 and driving the lower metal plate to displace, and the lower metal plate is used for pressing the metal wire 6 below and connecting the circuit.

[0027] When the handle 3 is rotated downwards, the cam 301 and the first connecting rod 302 rotate synchronously. Then, when the handle 3 is parallel to the upper surface of the housing 2, the side closest to the upper surface of the housing 2 contacts the metal plate at the upper end of the pressure plate assembly 4. As the handle 3 continues to rotate downwards, it presses the pressure plate assembly 4 to rotate synchronously. During rotation, the metal plate at the lower end of the pressure plate assembly 4 contacts and presses the two wires 6 below it. When the handle 3 reaches the predetermined position, the cam 301 presses the locking block 303, and the friction of the locking block 303 limits the cam 301, thus keeping the handle 3 fixed. At this time, the wires 6 below the pressure plate assembly 4 are connected through the metal pressure plate assembly 4 that presses the wires 6, completing the wiring of the wires 6. When the handle 3 is rotated upwards clockwise, the handle 3, through the spring 402 fixedly connected to it, pulls the pressure plate assembly 4 upwards, causing a certain rotational offset around the second connecting rod 401. At this time, the metal plate at the lower end of the pressure plate assembly 4 stops pressing the wires 6, and the wires 6 can be manually replaced and reconnected.

[0028] A connecting platform 502 is provided below the pressure plate assembly 4, and several support plates 501 are provided at the bottom of the housing 2. The upper surface of the support plates 501 is on the same plane as the upper surface of the connecting platform 502. The housing 2 has a first insertion port 202 and a second insertion port 203 that cooperate with the connecting platform 502. The first insertion port 202, the second insertion port 203, the support plates 501 and the connecting platform 502 are all matched in height. When the wire 6 is inserted parallel to the first insertion port 202 or the second insertion port 203, the wire 6 is placed above the support plate 501 and can be moved parallel to the connecting platform 502.

[0029] A first baffle 503 and a second baffle 504 are fixedly connected to the upper surface of the connecting platform 502. The first baffle 503 and the second baffle 504 are used to limit the insertion of the wire 6 to prevent it from being inserted too deeply or too shallowly. The first baffle 503 cooperates with the first insertion port 202. When the wire 6 is inserted straight into the first insertion port 202 and reaches the position of the first baffle 503, it reaches the predetermined position. The second baffle 504 cooperates with the second insertion port 203. When another wire 6 is inserted straight into the second insertion port 203 and reaches the position of the second baffle 504, it reaches the predetermined position. Baffles are provided on both sides of the pressure plate assembly 4. The distance between the baffles is greater than the width of the connecting platform 502. The baffles can form protection for the wire 6 on both sides of the connecting platform 502. Even if the wire 6 is deviated during the insertion process, as long as it is inserted into the space formed by the baffles on both sides of the pressure plate assembly 4, the wire 6 can be prevented from deviating further, ensuring the smooth connection of the wire 6.

[0030] The shell 2 is made of non-conductive plastic, so there is no risk of electric shock when operating the handle 3 made of rubber. The pressing plate assembly 4 is made of conductive metal, and when it presses the two wires 6, it itself becomes a conductor of the two wires 6. The second connecting rod 401 is provided on the pressing plate assembly 4 and is made of conductive metal. The shell 2 is provided with a test hole 2011, which cooperates with the second connecting rod 401. The second connecting rod 401 is clamped in the test hole 2011, and the distance from the side of the second connecting rod 401 close to the transparent plate 201 to the transparent plate 201 is 0.4-0.5 mm. This distance can ensure that the operator will not touch the second connecting rod 401 during manual operation. The pressing plate assembly 4 and the second connecting rod 401 are both made of conductive metal. When repairing or testing the terminal, the second connecting rod 401 in the test hole 2011 can be touched with a test pen from the side of the transparent plate 201, and the test pen reaction can be observed to detect or repair.

[0031] In use, the wires 6 are inserted into the terminal from the first insertion port 202 and the second insertion port 203, respectively. The wires 6 enter the side baffles of the pressing plate assembly 4 and continue to be inserted until they touch the first baffle 503 and the second baffle 504, and then stop inserting. During this process, the transparent plate 201 on one side of the shell 2 can be observed. Then the inserted wires 6 are kept straight. The handle 3 is held and rotated downward, and the cam 301 and the first connecting rod 302 are rotated synchronously. When the cam 301 rotates to a predetermined position, the cam 301 is pressed against the clamping block 303, and the clamping block 303 limits the cam 301. During the rotation of the handle 3, the pressing plate assembly 4 below the handle 3 is pressed to rotate synchronously, so that the metal plate at the lower end of the pressing plate assembly 4 directly presses on the two wires 6. At this time, the cam 301 at the predetermined position is limited, and the two wires 6 are connected by the conductive metal pressing plate assembly 4.

[0032] When it is necessary to disconnect the wires 6, the handle 3 is held and rotated upward, and the spring 402 on the handle 3 pulls the pressing plate assembly 4 to deflect around the second connecting rod 401, so that the pressing plate assembly 4 is separated from the wires 6. At this time, the wires 6 are disconnected, and the wires 6 can be replaced and checked manually.

[0033] When it is necessary to check and maintain the terminal, a test pen can be used to lightly touch one end of the second connecting rod 401 in the test hole 2011. Because the pressing plate assembly 4 and the second connecting rod 401 are both made of conductive metal, the second connecting rod 401 is electrified when the wires 6 are connected normally, and the second connecting rod 401 is not electrified when the connection of the wires 6 has a problem.

[0034] Compared with the prior art, the utility model has the advantages that the cam handle is used to control the connection and disconnection of the wire, and the wire terminal can be conveniently disconnected or reconnected without using a screwdriver.
