Abstract

The utility model discloses a tail accessory of an electric connector, which is characterized in that the peripheral wall of the tail accessory (1) is provided with a plurality of threaded holes along the circumferential direction, the tail accessory (1) is sleeved outside the tail part (2) of the electric connector, and the peripheral wall of the tail part (2) of the electric connector is provided with a sunk groove corresponding to the circumferential threaded holes of the tail accessory (1); and a set screw (3) passes through the threaded hole and is screwed into the sunken groove to fix the tail accessory (1) and the tail part (2) of the electric connector. The utility model adds the anti-loosing measure through a plurality of set screws, ensures the reliability of the connection between the tail accessory and the electric connector in the environment with severe vibration and impact magnitude, and has excellent anti-vibration and impact resistance; the spring is arranged in a counter bore on the inner part of the tail accessory, and the mechanical connection is firm and reliable. The tail accessory is suitable for environments with severe vibration and impact magnitude and high-speed rotation of cables.

Description

Tail accessory of electric connector

Technical Field

The utility model relates to an electric connector technical field, concretely relates to afterbody annex of electric connector.

Background

One end of the tail accessory of the electric connector is connected with the electric connector through threads, and the other end of the tail accessory of the electric connector is used for fixing a cable. The tail accessory is generally prevented from loosening by at least one of the following measures in use: a) the fuse penetrates through the fuse hole to prevent loosening; b) coating thread glue on the tail threads of the product and screwing the connecting nut to prevent loosening; c) and the tail accessory is integrally shrunk by a heat-shrinkable sleeve for preventing looseness. The anti-loosening measures are obviously insufficient only in environments with severe vibration and impact magnitude.

In the environment of high-speed rotation, the cable is easy to wear or break under centrifugal action, Chinese patent CN 109599217A mentions that the measure of adding a spring in the cable can effectively improve the problem, but does not mention how the spring is connected with the tail accessory.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an electric connector's afterbody annex suitable for vibration, the comparatively abominable and high-speed rotatory environment of cable of impact magnitude.

The technical scheme of the utility model is that:

the peripheral wall of the tail accessory is circumferentially provided with a plurality of threaded holes, the tail accessory is sleeved outside the tail of the electric connector, and the peripheral wall of the tail of the electric connector is provided with a sunk groove corresponding to the circumferential threaded holes of the tail accessory; and a set screw passes through the threaded hole and is screwed into the sunken groove to fix the tail accessory and the tail part of the electric connector.

For the cable which utilizes the spring to improve the wear resistance and the tensile resistance of the cable, a counter bore matched with the hook of the spring is arranged in the tail accessory, and the hook of the spring penetrates into the counter bore in the tail accessory and is fixed and anti-loose by the adhesive.

The utility model adds the anti-loosing measure through a plurality of set screws, ensures the reliability of the connection between the tail accessory and the electric connector in the environment with severe vibration and impact magnitude, and has excellent anti-vibration and impact resistance; the spring is arranged in a counter bore on the inner part of the tail accessory, and the mechanical connection is firm and reliable. The tail accessory is suitable for environments with severe vibration and impact magnitude and high-speed rotation of cables.

Drawings

Fig. 1 is a schematic structural diagram of the tail accessory of the electrical connector of the present invention.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As used herein, the term "plurality" refers to an indefinite number of the plural, usually more than two.

Fig. 1 is a schematic structural diagram of the tail accessory of the electrical connector of the present invention. As shown in the figure, the utility model discloses an electric connector's afterbody annex 1's perisporium is equipped with a plurality of screw holes along circumference, a plurality of screw holes are preferred to be followed afterbody annex 1's perisporium equipartition, and quantity is 3. The tail accessory 1 is sleeved outside the tail part 2 of the electric connector, and the peripheral wall of the tail part 2 of the electric connector is provided with a sunk groove corresponding to the peripheral threaded hole of the tail accessory 1; set screws 3 are passed through the threaded holes and screwed into the countersunk grooves in the peripheral wall of the electrical connector tail 2 to fix the tail attachment 1 and the electrical connector tail 2. The connection mode can obviously improve the anti-loosening grade of the connection between the tail accessory and the electric connector and has good vibration resistance and shock resistance.

For the cable which utilizes the spring to improve the wear resistance and the tensile resistance of the cable, the inside of the tail accessory 1 can be further provided with a counter bore 11 matched with the hook 41 of the spring 4, and the hook 41 of the spring 4 penetrates into the counter bore 11 in the inside of the tail accessory 1 and is filled with adhesive. The method has simple structure and reliable connection.

Claims
