Problems solved by technology

[0005] However, during the driving of the car, due to long-term vibration and bumps, the connector may become loose and cause the vehicle to malfunction; moreover, if the wire post at the connection is oxidized, it is easy to cause faults such as poor contact or even short circuit, while rain or moisture Violation is an important reason for this phenomenon
[0006] Therefore, it is necessary to ensure the stable connection of the connectors. The current common method is to use screws, locks and other methods to ensure the stable connection between the connectors; buckle etc. to achieve sealed connection, and also need to use heat shrink tube, waterproof sealant and other methods to seal the gap between the threading hole and the wire; these not only lead to increased volume of the connector, complex structure, high production cost, The assembly procedure is complicated and the production efficiency is low. In short, the improvement of the connector connection stability and waterproof sealing will eventually lead to an increase in the cost of the car, and it still cannot completely prevent the connector from loosening, water ingress and moisture, etc. occur
[0007] However, an obvious fact is that many connectors do not require frequent plugging and unplugging. After installation, some connectors may not be opened or pulled out until the entire car is scrapped. For these connectors, It is entirely possible to consider using a permanent package connection to completely prevent the connector from loosening, water ingress and moisture, etc., but the current connector is difficult to achieve this operation conveniently and at low cost

Embodiment 1

[0043] Such as Figure 1-3 As shown, a self-sealing automotive connector includes a matching plug 2 and a socket 1, the socket includes a first mounting plate 11 and a cylindrical first shell 12, the bottom of the first shell is provided with a first opening 13, The first mounting plate is fixed on the inner bottom of the first housing or at the first opening;

[0044] The side wall of the first shell is provided with interlayers, and glue 14 and compressed gas 15 are encapsulated in the inner cavity between the interlayers; the pressure of the compressed gas should not be too high, so as to prevent the glue from splashing too quickly and overflowing the connector or forming a large number of bubbles. The amount of sealing glue in the inner cavity between the interlayers should be able to fill the air everywhere in the connector but not overflow (for example, fill to the tubular extension). The compressed gas expands after the glue is pressed out of the interlayer, and the amo...

Embodiment 2

[0061] A method for using a self-styled automotive connector, comprising the following steps:

[0062] S1. Connect the pin assembly and the socket assembly to the wires, and make the first protective sleeve and the wire seal connected to prevent the glue from flowing out from the lower side of the first protective sleeve; rubber sealing rings, heat shrinkable tubes, and fillers can be added and other methods to realize the sealed connection between the first protective sleeve and the wire;

[0063] S2. Place the first shell of the socket upwards, and tear off the protective film if there is a protective film, so that the compressed gas gathers on the upper part of the inner cavity, and let it stand for a few seconds to reduce the bubbles in the glue;

[0064] S3. Insert the second shell of the plug into the socket facing downwards (positioning holes and positioning posts can be provided on the plug and socket respectively to facilitate alignment), the pin components and jack c...

Embodiment 3

[0067] Such as Figure 4 As shown, similar to Embodiment 1, the difference is that a number of optical fibers 7 with different lengths are arranged inside the second protective sheath, one end of the optical fiber is exposed in the tubular extension and forms a light source irradiation end 71, and the other end passes through Pass through the second mounting plate and enter the hollow space of the second housing.

[0068] The terminal points 72 of a plurality of optical fibers form a high-low arrangement in the second housing, so that the ultraviolet light can shine on each place during curing;

[0069] When the number of pin components is small, multiple optical fibers can be arranged in a straight line perpendicular to the second mounting plate; when the number of pin components is large, multiple optical fibers can be spirally coiled to prevent the optical fibers from affecting the insertion The inner wall of the second shell is set.

Abstract

The invention relates to a self-sealing automotive connector and a method of use thereof, comprising a matching plug and a socket, the socket including a first mounting plate and a cylindrical first shell; the side wall of the first shell is provided with an interlayer, Glue and compressed gas are encapsulated in the inner cavity between the interlayers; a liquid outlet is provided at the lower part of the inner side of the first shell, and a head / plug is provided at the liquid outlet; the plug includes a second mounting plate and is connected to the first The second housing that fits the inner space of the housing; when the plug is fully inserted into the socket, the second housing pushes the head / plug to allow the glue to flow out; the self-sealing automotive connector of the present invention is suitable for use in actual use After mating, the connector no longer needs to be pulled out; after mating, the glue is released to fill the gaps in the connector. After the glue is cured, it forms a permanent package, forming a filling and sealing protection for the gaps between the components. It greatly reduces the possibility of connector loosening, oxidation, short circuit and other problems during use.

Description

technical field [0001] The invention belongs to the technical field of connectors, and in particular relates to a self-sealing automobile connector and a using method thereof. Background technique [0002] Whether it is a conventional power vehicle or an emerging new energy vehicle, the automotive wiring harness is the bridge and link that constitutes the automotive circuit and connects the electrical components of the vehicle, and plays an irreplaceable role in the normal realization of vehicle functions. [0003] Due to the increase in functions and safety, automotive electronic control systems are becoming more and more complex. For connecting devices, that is, connectors, power lines, and signal lines (hereinafter collectively referred to as wires), the waterproof, dustproof, oxidation-proof performance, and current continuity and The requirements for stability, etc. are getting higher and higher; [0004] Automotive wiring harnesses generally use connectors, terminals,...
