Description

Technical Field

[0001] The utility model relates to the technical field of sockets, in particular to a reliably connected clip spring structure and a relay socket. Background Art

[0002] In order to protect the coil of the relay and eliminate reverse current during use, the relay socket is usually installed with a module with corresponding functions. The module is provided with multiple plug-in posts, each of which is provided with a conductive clip spring. When connected, the plug-in post is inserted into the corresponding socket in the socket body of the relay socket. At the same time, the conductive clip spring in the plug-in post clamps the module connection terminal configured in the socket. The module connection terminal is electrically connected to the load input terminal of the relay socket and the wire electrically connected between the relay insertion clip spring. During the clamping process, due to differences in parts processing and assembly methods, the module connection terminal and the wire may have poor contact, resulting in poor contact after some modules are installed in the relay socket, which in turn causes product failure. Utility Model Content

[0003] The utility model aims at the technical problems existing in the prior art and provides a reliably connected clip spring structure and a relay socket, which adopts an integrally formed clip spring structure to achieve reliable connection of modules.

[0007] Furthermore, a connecting arm is integrally formed between the load input terminal and the relay insertion clamp spring, the connecting arm is integrally formed with a support arm extending upward, and the jumper connecting terminal is integrally formed at the top of the support arm.

[0008] Furthermore, the module connection terminal is narrow at the top and wide at the bottom, so that the module connection terminal can be inserted upward into a corresponding hole on the socket body of the relay socket.

[0009] Furthermore, the load input terminal extends in a horizontal direction, and a surface of the load input terminal for contacting with the wire is provided with at least one convex rib protruding out of the surface.

DETAILED DESCRIPTION

[0021] In the description of the present invention, unless otherwise specified, "plurality" means two or more. In the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "setting", "connection", etc. should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection, a mechanical connection, an electrical connection, a direct connection, an indirect connection through an intermediate medium, or a connection between two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] See also Figure 1 As shown, a reliably connected clamp spring structure of the utility model includes a load input terminal 2, a relay insertion clamp spring 1 and a module connection terminal 3. The load input terminal 2, the relay insertion clamp spring 1 and the module connection terminal 3 are made by bending the same spring sheet multiple times, so that the load input terminal 2, the relay insertion clamp spring 1 and the module connection terminal 3 are an integrated structure. Specifically, a connecting arm 4 is integrally formed between the load input terminal 2 and the relay insertion clamp spring 1, and the module connection terminal 3 is integrally formed in the middle position of the connecting arm 4 and extends upward. The shape of the connecting arm 4 can be set according to actual needs. The load input terminal 2 and the relay insertion clamp spring 1 are roughly located at both ends of the connecting arm 4, and the load input terminal 2 extends in the horizontal direction.

[0023] As a preferred structure, the utility model further includes a jumper connection terminal 5, which is formed by bending a spring sheet, so that the jumper connection terminal 5 is an integrated structure with the load input terminal 2, the relay insertion clamp spring 1 and the module connection terminal 3. Specifically, the above-mentioned connecting arm 4 is integrally formed with an arm extending upward, the arm is parallel to the module connection terminal 3, and is located on the side of the module connection terminal 3 away from the relay insertion clamp spring 1, and the jumper connection terminal 5 is integrally formed at the top of the arm.

[0024] In this embodiment, the module connection terminal 3 is narrow at the top and wide at the bottom, so that the module connection terminal 3 can be inserted upward into the corresponding hole on the socket body of the relay socket. Specifically, an inclined step 31 is respectively provided on both sides of the width direction at the approximately lower middle part of the module connection terminal 3, so that the width of the module connection terminal 3 above the inclined step is narrower, and the width of the portion above the inclined step and above is larger.

[0025] In this embodiment, the surface of the load input terminal 2 for contacting with the wire is provided with one or more convex ribs 21 protruding from the surface, so that the load input terminal 2 can ensure reliable contact with the wire when connected to the wire. The multiple convex ribs 21 are arranged along the width direction of the load input terminal 2, and each convex rib 21 extends along the length direction of the load input terminal 2. Specifically, the number of the convex ribs 21 is two, but not limited to this. The convex ribs 21 are formed by stamping the load input terminal 2, but the forming method of the convex ribs 21 is not limited to this.

[0026] In this embodiment, the jumper connecting terminal 5 is in a horizontal U-shape, with the opening of the U-shape facing the extension direction of the load output terminal. Slots 51 are respectively provided on both sides of the U-shape, and the notches of the slots 51 are located on the end faces of the sides where they are located, and the width of the slots 51 increases from the outside to the inside.

[0027] The utility model provides a reliably connected spring clamp structure, wherein the load input terminal 2, the relay insertion spring clamp 1, the module connection terminal 3 and the jumper connection terminal 5 are an integrated structure. Therefore, the utility model makes it unnecessary for the module connection terminal 3 to be connected with the wire, and the problem of poor connection resulting from poor contact will not occur, thereby facilitating the reliable connection between the module and the relay socket. At the same time, the utility model also makes it unnecessary for the load input terminal 2 and the relay insertion spring clamp 1 to be connected with an additional wire, which ensures the reliability of the connection between the two on the one hand, and reduces the process of connecting the two wires on the other hand, thereby facilitating the improvement of production efficiency and the reduction of production costs. Similarly, the reliable connection between the jumper connection terminal 5 and the load input terminal 2 and the relay insertion spring clamp 1 can be ensured, and the connection process can be reduced, thereby improving production efficiency and reducing production costs.

[0028] See also Figure 2 , Figure 3 As shown, a relay socket of the present invention comprises a socket body 7, in which one or more reliably connected clip spring structures as described in the present invention are installed. Specifically, the number of the clip spring structures is two, but not limited thereto.

[0029] In this embodiment, a wire pressing frame 10 is provided inside the socket body 7 corresponding to the load input terminal 2, and the wire pressing frame 10 cooperates with screws to press one end of the external wire against the surface of the load input terminal 2 provided with the rib 21. When connecting the module 8 (the module is specifically a plug-in module, which is used to eliminate reverse current and protect the coil of the relay), the two plug-in columns 81 of the module 8 are respectively inserted into the socket body 7, and the conductive clamp springs provided in each plug-in column 81 clamp the corresponding module connection terminal 3 respectively; the jumper 9 used to connect other relay sockets is laterally inserted into the socket body 7, and each conductive terminal of the jumper 9 is respectively inserted into the slot 51 of the jumper connection terminal 5.
