Detailed Description

The present invention will be described in detail with reference to the following embodiments. The following examples will aid those skilled in the art in further understanding the present invention, but are not intended to limit the invention in any way. It should be noted that various changes and modifications can be made by one skilled in the art without departing from the spirit of the invention. These all belong to the protection scope of the present invention.

The utility model provides a fiber fixer, as shown in fig. 1-3, including body 1, body 1 has the fibre accommodation hole 11 that runs through along length direction, and fibre accommodation hole 11 is used for holding conductive fiber 2, and one side or both sides of body 1 have force application groove 12 respectively, and the thickness part between force application groove 12 and the fibre accommodation hole 11 allows to take place deformation when externally the application of force and then fix conductive fiber 2 who is arranged in fibre accommodation hole 11.

In practical applications, the cross-section of the fiber receiving hole 11 may have various configurations, such as a rectangular configuration, an oblong configuration, an elliptical configuration, or a circular configuration, the cross-section of the body 1 may have a rectangular configuration, an oblong configuration, an elliptical configuration, or a circular configuration, etc., or may have other configurations, preferably an oblong configuration as shown in fig. 1,

during assembly, the conductive fiber 2 is firstly installed in the fiber accommodating hole 11 and then extends into the force applying groove 12 through a tool to apply force and extrude to the thickness part, so that the thickness part is deformed, and finally the conductive fiber 2 is fixed in the body 1.

Further, the force application groove 12 may have various shapes, such as a rectangular, oblong, oval, or circular groove, which facilitates the force application tool to extend into the force application groove 12 for performing the pressing operation.

It should be noted that, the force application groove 12 on the side of the body 1 is recessed inwards along the outer side of the body 1, and the thickness part formed between the bottom surface of the force application groove 12 and the inner side of the body 1 has the advantage of being deformed by force application more easily, and the thickness part cannot cause the change of the appearance of the body 1 after being deformed, therefore, the design of the force application groove 12 makes the assembly of the fiber fixer more convenient and simple, which is beneficial to batch production, and improves the production efficiency of the product.

The body 1 is preferably integrally formed, and corners of the body 1 are chamfered for convenient assembly and operation.

When assembling, the front end and the rear end of the conductive fiber 2 in the body 1 are both protruded to the outside of the body 1, as shown in fig. 1, the length of the protrusion of the rear end of the body 1 is smaller than that of the protrusion of the front end of the body 1, and the design that the rear end of the conductive fiber 2 is also protruded to the outside of the body 1 is mainly to prevent the conductive fiber 2 from being effectively fixed when the thickness part is extruded and deformed due to the too short length of the conductive fiber 2 extending into the fiber accommodating hole 11.
