Description

Technical Field

[0001] The utility model relates to the technical field of electric connectors, in particular to a wire clamping structure at the tail of a connector. Background Art

[0002] Connectors are components that connect electronic components and wires and are widely used in various fields such as aviation, automotive, electronics, telecommunications, medical, and home appliances. Their primary function is to connect circuits and transmit signals. There are many types of connectors, including plugs, pin headers, sockets, and wiring harnesses.

[0003] Currently, the most common connector tailpieces are wire clamps, which effectively hold the wires in place. However, non-wire clamps, such as nut-shaped tailpieces, fail to secure the wires after soldering. The wires rotate circumferentially relative to the connector, and any pull on the wires can cause the solder joints to loosen or even fall off. A loose solder joint creates a weak contact between the wire and connector, increasing contact resistance and exacerbating temperature rise after prolonged operation, impacting system operation. A loose solder joint can cause a disconnection and system failure. Utility Model Content

[0004] The purpose of this utility model is to address the problem that the tail of existing non-clamping plate type connectors cannot effectively clamp the wires. A wire clamping structure is designed for the tail of the connector. This solves the problem that the tail of the connector without a clamping structure cannot clamp the wires, causing the wires to rotate and the solder joints to loosen or fall off when the wires are manually pulled. The following technical solutions are adopted:

[0005] A connector tail wire clamping structure includes a connecting tail and a tail fixing device, the tail fixing device is composed of a compression gasket, the connecting tail is provided with a wire outlet hole, and the hole wall of the wire outlet hole is provided with a threaded hole; the compression gasket is arranged between the connecting tail and the wire, one side of the compression gasket is provided as an arc surface, and the other side is provided as a plane; the arc surface of the compression gasket cooperates with the wire outlet hole of the connecting tail, and the plane of the compression gasket contacts the wire.

[0006] Preferably, the inner diameter of the wire outlet hole at the connecting tail is 8 mm, the hole depth is 10 mm, and an M3 threaded hole is provided 2.5 mm away from the end face.

[0007] Preferably, one side of the compression gasket is set to be an arc surface with a diameter of 8 mm, and the total height of the compression gasket is 2 mm and the total length is 6 mm.

[0008] Preferably, the cavity at the tail of the connector is filled with glue, and the height of the glue filling is greater than 6 mm from the end face of the connector tail.

[0009] Preferably, a set screw is provided in the threaded hole, one end of the screw presses against the arc surface of the compression gasket and is locked, and the wire is clamped and fixed.

[0010] Compared with the closest existing technology, the technical solution provided by the utility model has the following beneficial effects:

[0011] The utility model adopts a novel wire clamping structure which does not have its own clamping structure to connect the tail and the compression gasket, which solves the problem that the tail of the connector without its own clamping structure cannot clamp the wire, causing the wire to rotate by itself, and the risk that the solder joint will loosen or fall off when the wire is pulled manually. The structure is simple and can effectively clamp the wire. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] See also Figure 1-Figure 3 , the utility model provides a technical solution:

[0018] A wire clamping structure for the tail of a connector includes a connecting tail 1 and a tail fixing device, wherein the tail fixing device is composed of a clamping gasket 2. The connecting tail 1 is provided with a wire outlet hole 11, and a threaded hole 12 is provided on the hole wall of the wire outlet hole 11. The clamping gasket 2 is provided between the connecting tail 1 and the wire, and one side of the clamping gasket 2 is provided as a circular arc surface, and the other side is provided as a flat surface. The circular arc surface 21 of the clamping gasket cooperates with the wire outlet hole 11 of the connecting tail 1, and the flat surface 22 of the clamping gasket contacts the wire. The new wire clamping structure using a connecting tail 1 and a clamping gasket 2 without a self-contained clamping structure solves the problem that the connector tail without a clamping structure cannot achieve wire clamping, resulting in the wire rotating by itself, and the risk of the solder joint being loosened or falling off when the wire is manually pulled. The structure is simple and can effectively clamp the wire.

[0019] Furthermore, the inner diameter of the wire outlet hole 11 of the connecting tail 1 is 8 mm, the hole depth is 10 mm, and an M3 threaded hole 12 is provided 2.5 mm away from the end face.

[0020] Furthermore, one side of the compression gasket 2 is set to be an arc surface with a diameter of 8 mm, and the total height of the compression gasket 2 is 2 mm and the total length is 6 mm.

[0021] Furthermore, the cavity of the connector tail 1 is filled with glue, and the height of the glue filling is greater than 6 mm from the end face of the connector tail 1.

[0022] Furthermore, a set screw is provided in the threaded hole 12 , one end of the screw presses against the arc surface 21 of the compression gasket and is locked, and the wire is clamped and fixed.

[0023] The wire clamping mechanism at the connector tail works as follows: The connector tail 1 is pre-slipped onto the wire in the assembly direction. The wire is then stripped and soldered. The connector tail cavity is then filled with glue, ensuring the glue is at least 6 mm from the end face of the connector tail. After the glue dries, the connector tail 1 is assembled into place. The compression gasket 2 is placed directly below the threaded hole 12 of the connector tail 1. The arcuate surface 21 of the compression gasket mates with the wire outlet hole 11 of the connector tail 1, and the flat surface 22 of the compression gasket touches the wire. The end face of the compression gasket 2 is flush with the end face of the connector tail 1. A set screw is then installed in the threaded hole 12 of the connector tail 1. One end of the screw presses against the arcuate surface 21 of the compression gasket and is tightened, clamping the wire in place.

[0024] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the same. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the relevant field can still modify or replace the specific implementation methods of the present invention. Any modifications or equivalent replacements that do not depart from the spirit and scope of the present invention are within the scope of protection of the claims of the present invention to be approved.
