In the figure: 1. a perforator body; 10. the front end is open; 11. the rear end is open; 12. a side edge; 2. positioning a screw rod; 3. a nut; 4. a rubber member; 5. a wire harness.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example (b): referring to fig. 1 to fig. 2, an embodiment of the present invention provides a technical solution: an assembly auxiliary tool for a wire harness to penetrate through a rubber part comprises a perforator main body 1 with a C-shaped cross section, wherein the perforator main body 1 is of a semi-cylindrical structure with openings at two ends, the assembly auxiliary tool further comprises two positioning screws 2 and a nut 3 matched with the positioning screws 2 for use, the two positioning screws 2 are vertically fixed at the bottom of the rear end of the perforator main body 1, and the two positioning screws 2 are distributed side by side along the length direction of the perforator main body 1; during concrete implementation, fix perforator body 1 on the slide frock board through positioning screw 2 earlier, then with perforator body 1 front end cover put rubber spare 4, enlarge the line hole of crossing of rubber spare 4, utilize perforator body 1's inner chamber to wear to establish pencil and terminal at last, can be under the prerequisite of not damaging the terminal like this, comparatively smooth arrange the pencil in the line hole of crossing of rubber spare 4.

In order to make the piercing process of the piercer body 1 more smooth, in addition to the above embodiments, the diameter of the piercer body 1 of the present embodiment gradually increases from the front end opening 10 to the rear end opening 11, so that when the piercer body 1 is pierced, the smaller front end of the piercer body 1 can be inserted into the piercing hole of the rubber member 4 more smoothly, thereby facilitating the use of the piercer body 1.

In order to further facilitate the penetration of the perforator body 1 into the threading hole of the rubber 4, the front opening 10 of the perforator body 1 of this embodiment is cut into a bevel configuration based on the above embodiments, and the bevel configuration allows the front end of the perforator body 1 to be inserted into the threading hole of the rubber 4 more smoothly.

In order to avoid this problem, on the basis of the above embodiments, the two side edges 12 of the threading hole in the top of the perforator body 1 are both processed with round edges, the diameter of the processed side edge 12 is the same as the thickness of the perforator body 1, and the side edge 12 of the perforator body 1 after the round edge processing is not easy to scratch the inner wall of the rubber 4, thereby ensuring the stable performance of the rubber 4.

In order to ensure the connection strength between the positioning screws 2 and the perforator body 1, on the basis of the above embodiments, the top ends of the two positioning screws 2 of the present embodiment are welded and fixed to the perforator body 1, and of course, the positioning screws 2 may be connected to the perforator body 1 by other methods, such as clamping and screwing.

In order to facilitate the insertion or extraction of the perforator body 1 into or from the thread hole of the rubber 4, based on the above embodiments, the perforator body 1 of this embodiment is made of an elastic material, and during perforation, pressure may be artificially applied to both sides of the perforator body 1 to reduce the diameter of the perforator body 1, so that the perforator body may be more easily inserted into or extracted from the thread hole of the rubber 4, and the specific material of the perforator body 1 may be spring steel or high elastic plastic.

The working principle is as follows: firstly, fixing a perforator main body 1 on a slide plate tool plate through a positioning screw 2, sleeving a rubber part 4 at the front end of the perforator main body 1 to enlarge a thread passing hole of the rubber part 4, then placing a wire harness 5 into the perforator main body 1 through an opening at the top of the perforator main body 1, finally passing through the thread passing hole of the rubber part 4, and after the perforator main body 1 completely passes through the rubber part 4, withdrawing the perforator main body 1 from the thread passing hole.

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 alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
