Electric connector

Abstract

The utility model discloses an electric connecting piece, which comprises a plug shell and a matching shell, and a locking piece is rotationally arranged on the plug shell; the locking member is provided with a convex point, and the plug housing is also provided with a groove. The sound generated at the moment when the convex point makes contact with the groove is used for reminding a user that the locking piece is in a completely-opened state, and the phenomenon that the locking piece excessively rotates is avoided; and meanwhile, after the convex point is in contact with the groove, the resistance of the locking piece during rotation is improved, and then the problem that the locking piece continues to rotate due to misoperation is solved. On the basis, the equipment utilizes the sound generated by matching of the convex point and the groove to improve the opening state of the locking piece of a user, and the problem that the locking piece is damaged due to excessive rotation of the locking piece by the user is reduced.

Description

Technical Field

[0001] The utility model relates to the technical field of electrical connection devices, and specifically relates to an electrical connector. Background Art

[0002] In high-current high-voltage connectors, such as CN116093676A, after the operating unit and the mounting mechanism are closed, the operating unit is located on one side of the mounting mechanism. When the operating unit is opened, due to the lack of a limiting part, the operating unit is prone to excessive rotation. Since the electrical connector has strict requirements for insulation performance and weight, the operating unit is basically made of insulating plastic material. Therefore, once the operating unit rotates excessively, it is extremely easy to break it, and then the electrical connector loses its locking ability. Content of the Utility Model

[0003] The purpose of the utility model is to provide an electrical connector to solve the problems raised in the above background art.

[0004] To achieve the above purpose, the utility model provides the following technical solution: An electrical connector includes a plug housing and a mating housing, and a locking member is rotatably installed on the plug housing; a bump is provided on the locking member, and a groove adapted to the bump is further provided on the plug housing, and when the bump contacts the groove, a sound is emitted.

[0005] As a preferred technical solution of the utility model: An elastic plate is further provided on the locking member, and the bump is provided on the elastic plate.

[0006] As a preferred technical solution of the utility model: Avoidance grooves are provided on opposite surfaces of the locking member, and a first convex block is further provided on the plug housing, and the inner bottom surface of the avoidance groove abuts against the first convex block to prevent the rotation of the locking member.

[0007] As a preferred technical solution of the utility model: A second convex block is further provided on the inner bottom surface of the avoidance groove.

[0008] As a preferred technical solution of the utility model: The bump is hemispherical, and the groove is a hemispherical groove.

[0009] With the above technical solution, the beneficial effects of the present utility model are as follows: By utilizing the sound generated when the bump contacts the groove at the moment of contact, it reminds the user that the locking member is in a fully open state, avoiding the phenomenon of excessive rotation of the locking member; at the same time, after the bump contacts the groove, the resistance when the locking member rotates is increased, thereby reducing the problem of continuous rotation of the locking member caused by misoperation. In summary, on the one hand, this device can utilize the sound generated by the cooperation of the bump and the groove to improve the open state of the user's locking member, avoiding the phenomenon of excessive rotation; on the other hand, it utilizes the cooperation of the bump and the groove to increase the resistance of the locking member to rotate, avoiding the phenomenon of excessive rotation of the locking member. Based on this, through sound prompt and mechanical structure to prevent the locking member from rotating excessively, it reduces the problem of damage to the locking member caused by the user's excessive rotation of the locking member, thereby ensuring the service life of the locking member.

[0017] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0018] Please refer to Figures 1-6 , an embodiment provided by the present utility model: an electrical connector, including a plug housing 1 and a mating housing 2, and a locking member 21 is rotatably mounted on the plug housing 1; a bump 28 is provided on the locking member 21, and a groove 17 adapted to the bump 28 is further provided on the plug housing 1, and when the bump 28 contacts the groove 17, a sound is emitted.

[0019] In summary, by using the sound generated when the bump 28 contacts the groove 17 instantaneously, it is used to remind the user that the locking member 21 is in a fully open state, avoiding the phenomenon of excessive rotation of the locking member 21; at the same time, when the bump 28 contacts the groove 17, the resistance when the locking member 21 rotates is increased, and further, the problem of continued rotation of the locking member 21 caused by misoperation can also be reduced. Based on this, through sound prompt and mechanical structure to prevent the locking member 21 from rotating excessively, the problem of damage to the locking member 21 caused by the user rotating the locking member 21 excessively is reduced, and thus the service life of the locking member 21 is guaranteed.

[0020] Furthermore, since an elastic plate 29 is further provided on the locking member 21, and the bump 28 is provided on the elastic plate 29, therefore, when the bump 28 and the groove 17 are separated, the elastic plate 29 can extend outwardly from the locking member 21, facilitating the separation of the bump 28 and the groove 17.

[0021] Even further, since avoiding grooves 211 are provided on opposite surfaces of the locking member 21, and a first convex block 16 is further provided on the plug housing 1, and the bottom surface of the avoiding groove 211 abuts against the first convex block 16 to prevent the rotation of the locking member 21, therefore, by using the contact between the first convex block 16 and the bottom surface of the avoiding groove 211, the resistance to continued rotation of the locking member 21 after it is fully opened is further increased, and further, in cooperation with the bump 28 and the groove 17, the continued rotation of the locking member 21 is reliably prevented.

[0022] Meanwhile, since a second bump 210 is further provided on the inner bottom surface of the avoidance groove 211, the resistance to excessive rotation is increased by enlarging the contact area, effectively solving the problem that the locking member 21 is twisted off due to excessive rotation.

[0023] On the basis of the above solution, since the bump 28 is hemispherical and the groove 17 is a hemispherical groove, the separation of the bump 28 from the groove 17 is relatively smooth and fluent.

[0024] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention, and they still fall within the protection scope of the present invention.
