Description

Technical Field

[0001] The present application relates to the technical field of high-voltage connectors, and in particular to a protective connector socket. Background Art

[0002] The protection function of automotive products is very important. It is necessary to ensure that water or pollutants outside the components do not enter the connector and cause product connection and shielding failure. It is one of the most important indicators of new energy vehicle product quality.

[0003] Usually, high-voltage connector sockets assume that the interior of the car box they are mating with is a sealed environment. Therefore, a seal is made between the car box and the connector socket to prevent water and pollutants from the external environment from entering the connector. Since the car box is not a sealed environment, the environment inside the box may also cause impurities to enter the connector. How to improve the sealing effect of the connector socket is what technicians need to solve. Utility Model Content

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present application and its application or use.

[0027] Reference Figure 1 and 2 The present embodiment discloses a protective connector socket, which is installed on a box body 1 and includes a socket body 2, wherein the socket body 2 includes a plug-in portion 21 and a connecting portion 23, and a mounting plate 22 is integrally connected between the plug-in portion 21 and the connecting portion 23; a mounting hole 101 is provided on the box body 1, and a first sealing member 3 is provided on the side of the mounting plate 22 facing the box body 1, and the mounting plate 22 and the box body 1 are fixedly connected, the connecting portion 23 is placed in the box body 1, and a sealing component 7 for closing the connecting portion 23 is detachably installed on one end of the connecting portion 23 away from the plug-in portion 21.

[0028] One end of the connection portion 23 of the socket body 2 in this embodiment passes through the mounting hole 101 and enters the internal environment of the box body 1. At this time, the first sealing member 3 on the mounting plate 22 abuts against the box body 1, and the mounting plate 22 is fixed to the box body 1 with bolts. The sealing assembly 7 is installed at the rear end of the connection portion 23 to prevent impurities (dust, water) in the internal environment of the box body 1 from entering the socket body 2, thereby improving the safety of the connector itself.

[0029] Reference Figure 2 and 3 In this embodiment, at least two mounting grooves 221 are provided on the side of the mounting plate 22 facing the box body 1. The two mounting grooves 221 are arranged in inner and outer circles on the side of the mounting plate 22. The first sealing member 3 is placed in the mounting groove 221. It should be noted that the first sealing member 3 partially protrudes from the notch of the mounting groove 221, so that when the connector socket is finally installed, the first sealing member 3 can abut against the box body 1 and play a sealing role.

[0030] Reference Figure 3 and 4The sealing assembly 7 in this embodiment includes a sealing cover 4, the opening end of the sealing cover 4 is movably plugged into an end of the connecting portion 23 away from the plug-in portion 21, and the closed end of the sealing cover 4 is provided with a through hole for the cable to pass through. The inner circle of the sealing cover 4 is in contact with the outer circle of the connecting portion 23, and friction is generated between the two for a period of time, thereby ultimately ensuring the fixation of the sealing cover 4. This sealing cover 4 basically meets the requirements for use.

[0031] Continue to observe the attached Figure 3 and 4 This embodiment adds a positioning structure for the sealing cover 4. Figure 3 It can be seen that in this embodiment, four first limiting bodies 41 are arranged on the sealing cover 4, and the first limiting bodies 41 are symmetrically arranged on the opposite side walls of the sealing cover 4. A second limiting body 231 matching the first limiting body 41 is arranged on the outer wall of the connecting part 23. The first limiting body 41 and the second limiting body 231 are in contact with each other to fix the sealing cover 4. The first limiting body 41 here is opened in the limiting opening on the sealing cover 4, and the second limiting body 231 is a wedge-shaped block fixed on the outer wall of the connecting part 23. When in use, the sealing cover 4 moves to cover the connecting part 23 and moves. During manufacturing, the frame making material of the entire socket body 2 is made of plastic. The sealing cover 4 has a certain toughness. The sealing cover 4 moves until the wedge-shaped block passes through the limiting opening to complete the positioning. At this time, the setting of the structure greatly enhances the installation stability of the sealing cover 4, prevents the sealing cover 4 from loosening or even falling off during long-term use, and enhances the sealing of the connector socket while ensuring the use strength.

[0032] When disassembling, both sides of the sealing cover 4 are manually lifted up so that the limit opening is higher than the wedge-shaped block, and then the connecting portion 23 and the sealing cover 4 are relatively separated. It is convenient to use and simple to operate.

[0033] Observation attachment Figure 4 In some embodiments, the limiting protrusions 42 are axially connected along the connecting portion 23 on both sides of the limiting opening of the inner wall of the sealing cover 4. The spacing between each group of limiting protrusions 42 is equal to the width of the wedge block. When the sealing cover 4 moves, the limiting protrusions 42 can play a precise guiding role, so that the sealing cover 4 can be quickly installed.

[0034] In this embodiment, a second sealing member 5 is further provided on the perforated inner ring of the sealing cover 4, and a third sealing member 6 is further provided between the hole wall of the mounting hole 101 and the outer wall of the connecting portion 23. If necessary, a sealing member may be further provided between the sealing cover 4 and the connecting portion 23, and a through hole matching the perforation needs to be provided on the sealing member for the cable to pass through.

[0035] Preferably, the above-mentioned multiple seals all adopt colloid sealing rings, the center points of the plug-in portion 21 and the connecting portion 23 are axially colinearly arranged, a rectangular array of threaded through holes is provided on the surface of the mounting plate 22, and the mounting plate 22 is fixedly connected to the outer surface of the box body 1 with bolts.

[0036] The operating principle of this device is

[0037] The sealing cover 4 is sleeved on the tail end of the connecting part 23 and fixed by the first limiting body 41 and the second limiting body 231. At this time, the connecting part 23 is placed inside the box body 1 (car box body), and the mounting plate 22 is fixed with bolts. At this time, the gap between the box body 1 and the mounting plate 22 is sealed and blocked by the first sealing member 3, and the gap between the mounting hole 101 and the connecting part 23 is blocked and sealed by the third sealing member 6. The setting of the sealing cover 4 can basically meet the requirements of large particles of impurities entering the interior of the connector. The second sealing member 5 set in the perforation on the sealing cover 4 can block impurities in the internal environment of the box body 1 from entering the connector. The connector provided in the present application can achieve all-round sealing of the connector, has a high sealing level, and greatly improves the safety of use.

[0038] It is known from common technical knowledge that the present application can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the above disclosed embodiments are only illustrative in all respects and are not exclusive. All changes within the scope of the present application or within the scope equivalent to the present application are included in the present application.
