Description

Technical Field

[0001] This utility model relates to the field of connector technology, and more specifically to a quick-plug waterproof connector. Background Technology

[0002] In industries such as petroleum, chemical, power, and telecommunications, equipment is often exposed to rain, humidity, or corrosive environments, making it difficult for traditional connectors to meet waterproofing requirements. Against this backdrop, waterproof connectors have emerged. These connectors typically employ a sealed structure and special materials to prevent water, dust, and contaminants from entering, ensuring stable current transmission in humid environments and preventing leakage or signal interruption.

[0003] However, when most of these connectors are used in equipment that requires frequent replacement or debugging, the frequent and time-consuming insertion and removal operations, coupled with the sealing and fixing structure, often require tools or multiple steps to reduce the difficulty of operation for the user. Although this is more labor-saving, it leads to low equipment debugging efficiency. In addition, under long-term use, vibration environment, and repeated insertion and removal, the connector is prone to loosening at the mating point. This is due to insufficient mechanical holding force or wear of the contact parts, which in turn leads to increased contact resistance, signal interruption, or even open circuit failure, affecting system reliability.

[0004] To address the aforementioned issues, this application provides a quick-plug waterproof connector. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a quick-plug waterproof connector to solve the problems existing in the background art.

Detailed Implementation

[0016] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The quick-plug waterproof connector involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] Reference Figure 1 and Figure 2 As shown, this utility model provides a quick-plug waterproof connector, including a connector assembly 1 and an inner push assembly 2 installed on the outside of the connector assembly 1. A wiring assembly 3 is fixedly welded on the connector assembly 1, and a sealing assembly 4 and a fixing assembly 5 are installed on the inner push assembly 2.

[0018] Reference Figure 2 As shown, the inner push assembly 2 includes a housing 201, a push groove 202, a slider 203, a compression spring 204, and a limiting arc groove 205. There are two plug pieces 101, which are respectively wrapped around the outside of the plug piece 101 and the connector piece 102. Each of the plug piece 101 and the connector piece 102 is provided with four sliders 203. The housing 201 is provided with corresponding push grooves 202 at the connection points. The compression spring 204 is located in the push groove 202 on the side away from the slider 203. The outer side of the housing 201 on the left side is provided with a limiting arc groove 205. After the insertion operation is performed, the internal plug piece 101 and connector piece 102 are pushed towards the center by the corresponding sliders 203 under the action of their respective compression springs 204, so that the plug piece 101 is always tightly inserted with the connector piece 102.

[0019] Reference Figure 2 As shown, the connector assembly 1 includes a plug 101, a connector 102, and pins 103. The plug 101 and the connector 102 are respectively disposed on the left and right sides, and the tail ends of the plug 101 and the connector 102 are provided with multiple pins 103.

[0020] Reference Figure 2 As shown, the wiring assembly 3 includes a main wire 301, a sub-wire 302, and a sealing rubber sleeve 303. The main wire 301 passes through a through hole at the tail end of the housing 201 and enters the interior of the housing 201. Multiple sub-wires 302 are drawn out from the main wire 301 and are fixedly soldered to the corresponding pins 103. The sealing rubber sleeve 303 is set at the connection between the through hole at the tail end of the housing 201 and the main wire 301. At this time, the plug 101 and the connector 102 can be electrically connected to the corresponding main wire 301 by soldering the sub-wires 302 to the pins 103. The sealing rubber sleeve 303 seals and waterproofs the connection.

[0021] Reference Figure 2 As shown, the sealing assembly 4 includes a protruding insert 401, a first sealing ring 402, and a second sealing ring 403. The sealing assembly 4 is located on the right side of the overall connector. The protruding insert 401 is located at the interface on the right side of the outer shell 201. The first sealing ring 402 is located at the connection between the protruding insert 401 and the outer shell 201 and wraps around the outer ring of the protruding insert 401. The protruding insert 401 is snapped onto the outer side of the middle part of the protruding insert 401. The length of the protruding insert 401 is less than the connector length of the head of the plug 101. After the interfaces of the outer shells 201 on both sides are fully fitted together, the first sealing ring 402 is pressed tightly at the connection between the first sealing ring 402 and the inner wall of the left outer shell 201. At the same time, it works with the second sealing ring 403 located at the interfaces of the two outer shells 201 to buffer and seal the connection.

[0022] Reference Figure 2 and Figure 3 As shown, the fixing assembly 5 includes a rotating arm 501, a first pressure rod 502, a rotating column 503, a spiral spring 504, a limiting block 505, a lower pressure arm 506, and a second pressure rod 507. The rotating arm 501 is located on the front and rear sides of the outer shell 201 on the left side. The first pressure rod 502 is fixedly connected between the two rotating arms 501. The rotating column 503 is rotatably engaged with the end of the rotating arm 501 away from the first pressure rod 502 and is fixedly installed on the side wall of the outer shell 201. One end of the spiral spring 504 is movably sleeved on the spiral spring 504, and one end is fixedly connected to the rotating arm 501, while the other end is fixedly connected to the outer shell 201. The limiting block 505 is engaged in the limiting arc groove 205 opened in the outer shell 201 and is fixedly installed on the rotating arm 501. The second pressure rod 507 has the lower pressure arm 506 fixedly installed at both ends, and the lower pressure arm 506 is fixedly installed on the rotating arm 501.

[0023] Based on the above structure, during connector insertion and removal, press the second pressure rod 507 towards its center, causing the fixing assembly 5 to rotate outward along the main axis of the rotating column 503. Then, push the outer shells 201 on both sides towards the center and release the second pressure rod 507. At this time, under the action of the spiral spring 504, the fixing assembly 5 will deflect towards the center along the main axis of the rotating column 503 until the first pressure rod 502 is engaged in the long slot on the right outer shell 201. This process fixes the inner pushing assemblies 2 on both sides relatively. During the deflection process, the fixing assembly 5 is limited by the limiting arc groove 205 on the outer shell 201.

[0024] Based on the accompanying drawings and the foregoing description, the working principle of this utility model can be roughly described as follows:

[0025] When using this interface, the sub-line 302 needs to be connected to the pin 103 to achieve electrical connection between the plug 101 and connector 102 and the corresponding main line 301. The sealing rubber sleeve 303 is used to waterproof the connection. During the insertion operation, press the second pressure rod 507 towards the center to rotate the entire fixing assembly 5 outward along the main axis of the rotating column 503. At this time, push the outer shells 201 on both sides towards the center to make the socket of the connector 102 engage with the plug of the plug 101. Continue pushing until the interfaces of the outer shells 201 on both sides are completely fitted.

[0026] During this process, the No. 1 sealing ring 402 is pressed tightly against the inner wall of the left outer shell 201 and the connection point of the No. 1 sealing ring 402. At the same time, the No. 2 sealing ring 403 located at the interface of the two outer shells 201 buffers and seals the connection point. Then, the No. 2 pressure rod 507 is released, and the fixing component 5 deflects along the main axis of the rotating column 503 under the action of the spiral spring 504 until the No. 1 pressure rod 502 is engaged in the long groove opened on the right outer shell 201, so that the inner pushing components 2 on both sides are relatively fixed.

[0027] During the overall deflection action of the fixed component 5, the fixed component 5 is limited by the limiting arc groove 205 opened on the outer shell 201. At the same time, the plug 101 and connector 102 inside are pushed towards the center by the corresponding slider 203 under the action of the spring 204 within their respective ranges, ensuring that the plug 101 is always tightly inserted with the connector 102. At this time, the plug 101 and connector 102 are firmly connected and not easy to fall off. The sealing rubber sleeve 303 fits tightly at the connection, effectively preventing water from seeping in and ensuring the waterproof performance of the connector. The entire insertion and removal process is simple and quick. For online communication systems or other facilities that need to be connected by cables, the shorter the maintenance time, the sooner the work can be restored. Therefore, the above structure has reasonable practical significance.

[0028] The above technical solutions and their reasonable combinations can also effectively demonstrate the following technical effects:

[0029] Firstly, the designed spiral spring 504 not only realizes the automatic reset function of the fixing component 5, but also enhances the structural stability of the entire connector to a certain extent, so that the connector can still maintain a good working condition after multiple insertions and removals.

[0030] Secondly, the double sealing design of the No. 1 sealing ring 402 and the No. 2 sealing ring 403 greatly improves the waterproof rating of the connector, ensuring that the internal electrical connection of the connector is not affected even in a humid environment lacking maintenance.

[0031] Thirdly, the design of the limiting arc groove 205 not only restricts the rotation range of the fixing component 5, but also plays a guiding role, making the insertion and removal process smoother and reducing the difficulty of operation.

[0032] Finally, several points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly, and can refer to mechanical or electrical connections, or internal connections between two components, or direct connections. "Up," "down," "left," and "right," etc., are only used to indicate relative positional relationships.
