Description

Technical Field

[0001] The utility model relates to the technical field of electric connectors, in particular to a shockproof locking structure of a plug-in connector. Background Art

[0002] Electrical connectors, essential components for signal transmission and exchange in electronic terminals, are widely used in a variety of fields, including automotive, communications, computing, industry, transportation, and military. With the rapid development of these sectors, the demand for electrical connectors continues to increase. This is particularly true in new energy vehicles, 5G communications, and consumer electronics, where the demand for high-speed, high-frequency, high-voltage, and high-current electrical connectors is particularly urgent. With the miniaturization and modularization of entire systems, electrical connectors are also required to achieve smaller size and higher density. This requires the design of electrical connectors to utilize more sophisticated mold manufacturing technology, as well as more optimized layout and structural design.

[0003] When implementing this technical solution, at least the following drawback still exists: existing electrical connectors typically rely on plug-in and pull-out methods to connect to plug connectors. However, due to external vibrations, this can easily lead to loose connections between the plug connector and the connector body, thereby affecting signal transmission. This urgently requires improvement. Therefore, we propose a vibration-proof locking structure for plug-in connectors. Utility Model Content

[0004] The purpose of the present invention is to provide a shockproof locking structure for a plug-in connector, which solves the problem in the background art that the connection between the plug connector and the connector body may become loose due to external vibration factors, thereby affecting the transmission of signals.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a plug-in connector anti-vibration locking structure, comprising a connector body, a locating ring provided at one connecting end of the connector body, a plug connector provided on one side of the locating ring, arcuate grooves symmetrically formed on the inner wall of the locating ring, a locating cavity provided at the end of the arcuate groove, and locating blocks fixedly mounted at both ends of the plug connector;

[0006] A receiving groove is provided on one side of the positioning cavity, a fixing block is provided in the inner cavity of the receiving groove, a pressing piece is fixedly installed on one side of the fixing block, sliding grooves are provided at the upper and lower ends of the receiving groove, and sliders are fixedly installed on both sides of the fixing block.

[0007] By adopting the above technical solution, the fixed block can drive the pressing piece to press against one side of the positioning block, thereby pressing and limiting the positioning block, and thus plugging and locking the plug connector, and the spring on the fixed block can cooperate with the rubber sheet on the pressing piece to absorb the vibration energy transmitted to the positioning block, thereby reducing the impact of external vibration factors, thereby reducing the situation where the positioning block falls out of the arc groove, and thus ensuring the stability of the connection between the plug connector and the connector body.

[0008] Optionally, the size of the positioning block is adapted to the size of the arc-shaped slot, and the positioning block is movably connected to the arc-shaped slot.

[0009] By adopting the above technical solution, the positioning block cooperates with the arc groove, thereby ensuring the stability of the connection between the plug connector and the positioning ring.

[0010] Optionally, a rubber sheet is bonded to one side of the pressing sheet, and the size of the rubber sheet matches the size of the pressing sheet.

[0011] By adopting the above technical solution and arranging the rubber sheet, the generated vibration energy can be buffered and absorbed, thereby reducing the impact caused by the vibration.

[0012] Optionally, a curved surface is provided on one side of the pressing plate close to the arc groove.

[0013] By adopting the above technical solution and setting the arc surface, when the positioning block enters the positioning cavity, the positioning block pushes the arc surface, thereby driving the fixing block into the accommodating groove, thereby facilitating the positioning block to be inserted into the positioning cavity.

[0014] Optionally, the size of the slider is adapted to the size of the slide groove, and the slider is slidably connected to the slide groove.

[0015] By adopting the above technical solution, the slider cooperates with the slide groove, thereby ensuring the stability of the movement of the fixed block, thereby facilitating the fixed block to press and limit the positioning block.

[0016] Optionally, a spring is fixedly installed in the inner cavity of the slide groove, and the other end of the spring is fixedly connected to the slider.

[0017] By adopting the above technical solution and arranging the spring, the pressing piece on the fixing block can be driven to press against one side of the positioning block by virtue of the spring's resilience.

[0018] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0019] The technical solution of the present application, through the provision of the connector body, positioning ring, arc-shaped groove, pressure piece, arc surface, rubber sheet and spring, can not only enable the fixed block to drive the pressure piece to press against one side of the positioning block, thereby pressing and limiting the positioning block, and thus plugging and locking the plug connector, but also can absorb the vibration energy transmitted to the positioning block through the cooperation between the spring on the fixed block and the rubber sheet on the pressure piece, thereby reducing the influence of external vibration factors, thereby reducing the situation of the positioning block falling out of the arc-shaped groove, and thus ensuring the stability of the connection between the plug connector and the connector body.
