The wire core fixing of existing crimp terminals is poor, which can easily lead to loosening of the wire core.
A press terminal is designed, and an extrusion portion convex toward the middle is provided on the inner walls of the left and right sides of the threading hole. When the screw part of the pressing bolt squeezes the wire core, the extrusion portion can squeeze the wire core together to improve the fixing firmness.
Through the joint extrusion effect of the extrusion part, the fixing firmness between the wire core and the terminal body is significantly improved, the wire core is avoided, and the wire core is further prevented from being disengaged when the multi-core wire is fixed.

[0004] The utility model provides a wire-pressing terminal, comprising a terminal body, a wire-threading hole penetrating the terminal body from front to back, an inner top of the wire-threading hole forming a first arc surface for abutting against a wire core, a threaded hole communicating with the wire-threading hole is provided on the lower end of the terminal body, the threaded hole is used for a screw rod portion of a wire-pressing bolt to pass through and be threadedly connected with the screw rod portion of the wire-pressing bolt; both left and right inner walls of the upper part of the wire-threading hole are provided with extrusion portions convex inwardly toward the middle part of the wire-threading hole, and both front and rear ends of each extrusion portion extend to the front end and the rear end of the terminal body respectively; when the screw rod portion of the wire-pressing bolt squeezes the wire core located in the wire-threading hole, the extrusion portion is used for squeezing the wire core so that the terminal body can reliably press the wire core.
[0005] When the utility model is in use, when the wire pressing bolt squeezes the wire core of the wire inserted into the wire threading hole, the two squeezing parts can squeeze the wire core of the wire together, thereby improving the fixing firmness of the wire core and the terminal body to avoid the wire core from loosening relative to the terminal body; in addition, when fixing the wire core of the multi-core wire, after the wire core of the multi-core wire is inserted into the wire threading hole, the squeezing part can squeeze the wire core of the multi-core wire and make the wire core of the multi-core wire gather together, further preventing the wire core from detaching from the terminal body.
[0006] In a possible implementation, the inner wall surface of the extrusion portion forms a second arc surface; by setting the inner wall surface of the extrusion portion to the second arc surface, when the extrusion portion extrudes the core of the wire, it can be avoided that the extrusion portion cuts the core of the wire.
[0007] In a possible implementation, the junction between the extrusion portion and the first arc surface is transitioned through a third arc surface; by adopting this structure, when the core of the wire contacts the junction between the extrusion portion and the first arc surface, the core of the wire can be prevented from being cut.
[0008] In a possible implementation, the extrusion portion and the inner wall of the threading hole located below the extrusion portion transition through a fourth arc surface; by adopting this structure, when the core of the wire contacts the extrusion portion and the connection point of the inner wall of the threading hole located below the extrusion portion, the core of the wire can be prevented from being cut.
[0009] In a possible implementation, the extrusion portion is integrally formed with the terminal body; by adopting this structure, the advantages of high connection strength and high connection reliability between the extrusion portion and the terminal body are achieved, and the terminal body can be easily processed.
