Technical Field
[0001] The utility model belongs to the technical field of relays, and particularly relates to a high-safety wiring terminal for a relay. Background Technique
[0002] A relay is an electrical control device. When the change of the input quantity (excitation quantity) reaches the specified requirement, it is an electrical appliance that makes the controlled quantity have a predetermined step change in the electrical output circuit. It has an interactive relationship between a control system (also called an input circuit) and a controlled system (also called an output circuit). It is usually applied to an automatic control circuit. It is actually an "automatic switch" that uses a small current to control the operation of a large current. Therefore, it plays roles such as automatic regulation, safety protection, and circuit conversion in the circuit, and the wiring terminal on the relay is a fitting product used to achieve electrical connection.
[0003] For traditional relay wiring terminals, usually the wire ends are wound around the terminals, and then the wire ends are fixed by tightening nuts, thus completing the fixed installation of the wire ends.

[0020] The following further describes the present utility model in conjunction with embodiments.
[0021] The following embodiments are used to illustrate the present utility model, but cannot be used to limit the protection scope of the present utility model. The conditions in the embodiments can be further adjusted according to specific conditions. Any simple improvement to the method of the present utility model under the premise of the concept of the present utility model belongs to the scope protected by the present utility model.
[0022] Please refer to Figures 1-5 , the present utility model provides a highly secure wiring terminal for a relay, including a protective housing 1. A wiring assembly 2 is arranged inside the protective housing 1. The wiring assembly 2 includes a built-in groove 201 which is opened inside the protective housing 1. A protective cylinder 202 is movably connected inside the built-in groove 201. A fixed ring 203 is fixedly connected inside the protective cylinder 202. An extension ring 204 is arranged on one side of the fixed ring 203. Wiring clamping blocks 205 are evenly arranged in a plug-in manner along the circumferential direction inside the extension ring 204. A fixing assembly 3 is arranged on the top of the extension ring 204. When it is necessary to connect and fix a wire, the staff can first insert the wire into the built-in groove 201, and then push the screwing block 305 towards the limit ring 302 by the staff. At this time, under the guiding action of the fixed ring 203, the extension ring 204 moves away from the limit ring 302 towards the wiring clamping block 205, so as to contract and clamp the wiring clamping block 205, and the connection and fixation of the wire inside the wiring clamping block 205 are realized.
[0023] Specifically, as Figure 1 , Figure 3 , Figure 4 and Figure 5 shown, the fixing assembly 3 includes a tensile column 301 which is fixedly connected to the top surface of the extension ring 204, and the tensile column 301 is rotationally and cooperatively connected to the outer wall of the protective cylinder 202. A limit ring 302 is sleeved on the side surface of the tensile column 301.
[0024] Specifically, as Figure 1, Figure 3 , Figure 4 and Figure 5 As shown in Figure 3 , Figure 4 , and Figure 5 , a rotating shaft 303 is movably connected inside the stretching column 301, and a limiting block 304 is fixedly connected to the top of the stretching column 301.
[0025] When it is necessary to connect and fix the electric wire, the staff can first insert the electric wire into the built-in groove 201, and then the operator pushes the screwing block 305 to move towards the limiting ring 302. At this time, under the guiding action of the fixed ring 203, the extending ring 204 moves away from the limiting ring 302 towards the wiring clamping block 205, so as to contract and press the wiring clamping block 205, and the connection and fixation of the electric wire inside the wiring clamping block 205 are realized.
[0026] Specifically, as Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown in Figure 1 , Figure 3 , Figure 4 , and Figure 5 , one end of the stretching column 301 is fixedly connected with a screwing block 305, a spring ring 306 is sleeved on the side surface of the stretching column 301, a connection component 4 is arranged on the top of the protective shell 1, and when the staff holds the screwing block 305 and rotates and pushes, the angle of the stretching column 301 will be adjusted accordingly and it can drive the extending ring 204 connected to its bottom to move together.
[0027] Specifically, as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , and Figure 5 , the connection component 4 includes a connection block 401. The connection block 401 is fixedly connected to the top of the protective shell 1. A connection groove 402 is opened inside the connection block 401. A fixing groove 5 is opened on the back of the protective shell 1. A blocking plate 6 is fixedly connected to the inner wall of the top of the protective shell 1. And the spring ring 306 is located between the limiting ring 302 and the blocking plate 6 on the side close to the limiting block 304. When it is necessary to connect multiple wiring terminals together, the staff can insert a rope or an electric wire into the connection groove 402 opened in the connection block 401 for convenient connection.
[0028] Working principle and usage process of the present utility model:
[0029] First of all, when it is necessary to connect and fix the electric wire, the staff can first insert the electric wire into the built-in groove 201, and then the staff pushes the screwing block 305 to move towards the limiting ring 302 (at this time, under the guiding action of the fixing groove 5, the limiting block 304 drives the screwing block 305 to move) until the end face of the side of the limiting block 304 close to the limiting ring 302 is tangent to the inner wall of the protective shell 1;
[0030] Next, the staff rotates the screw block 305 until the limit block 304 is completely out of the fixing groove 5 (and the screw block 305 is rotated at an angle of 180 degrees);
[0031] During this process, the limit ring 302 drives the spring ring 306 to move toward the wiring card block 205 until it contacts the blocking plate 6 and is compressed, that is, the elastic properties of the spring ring 306 provide a stable contact force between the limit block 304 and the protective housing 1, thereby ensuring the firmness of the position of the tensile column 301;
[0032] Finally, the extension ring 204 moves toward the horizontal section of the wiring block 205 under the synchronous action of the stretching column 301. Since the vertical distance between the wiring block 205 and the axis of the stretching column 301 gradually increases from one end close to the limiting ring 302 to the other end, when the extension ring 204 moves away from the limiting ring 302, the wiring block 205 gradually moves toward the axis of the stretching column 301 under the limiting action of the extension ring 204, thereby implementing resistance clamping for the wires coaxially distributed with the stretching column 301, thereby achieving stable clamping of the wire port, and fully ensuring the stability of the wire connection;
[0033] The process of releasing the clamping of the wiring clamp block 205 on the wires:
[0034] The specific implementation principle can refer to the clamping of the wire port by the aforementioned wiring clamp block 205;
[0035] When it is necessary to release the restriction of the wire port, the operator reverses the screw block 305 until the limit block 304 is re-engaged with the fixing groove 5. After that, the screw block 305 controls the stretching column 301 to drive the extension ring 204 to return to the initial position under the dual effects of the guidance of the fixing groove 5 and the reset of the spring ring 306, that is, the extension ring 204 gradually releases the restriction of the wire clamping block 205, thereby realizing the "unbinding" of the wire port;
[0036] When multiple wiring terminals need to be connected together, the staff can insert a rope or wire into the connection slot 402 provided in the connection block 401 to facilitate the connection.
[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
