Description

Single waterproof electric connector socket

Technical Field

The invention relates to the technical field of electric connectors, in particular to an independent waterproof electric connector socket with an independent waterproof function.

Background

For new energy automobiles, the electrical connector is an important component. The electric connector generally comprises plug and socket, and plug and socket are equipped with seal structure to the face of inserting, and waterproof grade can reach IP67 after inserting, but in the use, once to the sealing washer inefficacy (or plug and socket separation) of face of inserting, because do not design waterproof construction between socket casing and the shield cover, liquid can get into the box inside from the shielding layer this moment, causes short circuit and electric leakage accident.

Disclosure of Invention

The invention overcomes the defects of the prior art and provides the independent waterproof electric connector socket with the independent waterproof function. Under the state that plug and socket are not inserted, even if have liquid splash to the socket inside, liquid also can not get into the box inside from socket shield cover, and waterproof performance just can waterproof electric connector be higher after inserting, be fit for using widely.

In order to solve the technical problems, the invention adopts the following technical scheme:

a single waterproof electrical connector receptacle comprising: an integrated socket shell, a shielding cover and a wiring terminal; the integrated socket shell comprises a socket shell and an insulating mounting plate; the shield is mounted on the socket housing; the insulation mounting plate is provided with a mounting via hole, a shielding pin window, an outer sealing ring mounting groove and an inner sealing ring mounting groove; a shielding pin is arranged at the bottom of the shielding cover and penetrates through the shielding pin window;

further comprises: an outer seal ring and an inner seal ring; the outer sealing ring is arranged in the outer sealing ring mounting groove; the inner sealing ring is arranged in the inner sealing ring mounting groove.

The shielding pin is characterized in that the tail end of the shielding pin is provided with an outward bending structure.

The shielding pin window is positioned between the outer sealing ring mounting groove and the inner sealing ring mounting groove.

The further technical proposal is that the top of the shielding cover is provided with a ruffle for fixing the integrated socket shell, and the side surface is provided with a meshing part.

The further technical scheme is that the novel connecting terminal further comprises a sealing plug, and the sealing plug is sleeved at the rear part of the connecting terminal.

The further technical proposal is that the sealing plug is formed by a rubber pressing process.

The further technical scheme is that the outer sealing ring is formed through a rubber pressing process.

The further technical scheme is that the inner sealing ring is formed by a rubber pressing process.

Compared with the prior art, one of the beneficial effects of the embodiment of the invention is as follows:

1. compared with the shielding cover adopted by the common connector socket, the design of the bottom pins is generally straight up and down, and the shielding cover is tightly attached to the outer wall of the insulating mounting plate after being installed into the socket shell, so that the shielding pin window on the shell flange plate is required to be tightly attached to the outer wall of the insulating mounting plate, and no redundant space exists between the shielding window and the outer wall of the insulating mounting plate to design a waterproof structure; according to the shielding cover adopted by the invention, the bottom pins are bent outwards (bending is only one expression mode), and the shielding cover is clung to the outer wall of the insulating mounting plate after assembly, but because the bottom pins are extended, the shielding window on the flange plate of the shell can outwards deviate along the outer wall of the insulating mounting plate, and enough space can be reserved between the shielding pin window and the insulating mounting plate to place an inner sealing ring, so that independent waterproof of a socket is realized.

2. Compared with the structure that the bottom of the common socket flange only comprises one sealing ring, the socket flange adopts a double-sealing ring design, an inner sealing ring is additionally arranged, and a shielding pin window on the flange is arranged between the inner sealing ring and the outer sealing ring, so that liquid is isolated between the inner sealing ring and the outer sealing ring after flowing through the shielding pin window and cannot flow into the box body.

Detailed Description

All of the features disclosed in this specification, or all of the steps in a method or process disclosed, may be combined in any combination, except for mutually exclusive features and/or steps.

Any feature disclosed in this specification (including any accompanying claims, abstract and drawings), may be replaced by alternative features serving the same, equivalent or similar purpose, unless expressly stated otherwise. That is, each feature is one example only of a generic series of equivalent or similar features, unless expressly stated otherwise.

The following describes in detail the embodiments of the present invention with reference to the drawings and examples.

In the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the disclosed embodiments, however, it is apparent that one or more embodiments may be practiced without these specific descriptions and that in other examples, well-known structures and devices are schematically shown in order to simplify the drawings.

As shown in fig. 1 to 4, according to an embodiment of the present invention, the individual waterproof electrical connector receptacle disclosed in this embodiment includes a shield case 1, an integral receptacle housing 2, a screw sleeve 3, an outer seal ring 4, an inner seal ring 5, a seal plug 6, and a connection terminal 7. Wherein the inner sealing ring is used for preventing liquid from entering the box body from the inside of the socket; the sealing plug is used for preventing liquid from entering the box body from the wiring terminal; the wiring terminal is used for connecting a cable; the screw sleeve is used for installing a socket.

In this embodiment, the integrated socket housing is formed by integrally injection molding a socket housing and an insulating mounting plate 11, a flange is arranged at the bottom of the integrated socket housing, and a shielding pin window 8 for a shielding pin to pass through, an outer sealing ring mounting groove 9 for placing an outer sealing ring 4, and an inner sealing ring mounting groove 10 for placing an inner sealing ring 5 are arranged on the flange.
