Description

Technical Field

[0001] The utility model relates to the technical field of connectors, and particularly relates to a connector with a gear locking function. Background Art

[0002] Connectors are mainly used to connect data, signals, and power between network devices and mechanical devices; it is a device that bridges two conductors on a loop, allowing current or signals to flow from one conductor to another. Connectors are also known as circuit connectors or line connectors. With the rapid development of the global economy, the industries where connectors are located in China, such as medical equipment, aerospace and military, automotive, communication, computers, consumer electronics, and industry, have developed rapidly, making the Chinese connector market always maintain a high growth rate, and the market scale of connectors has continuously expanded. For existing connectors, two active devices are connected by a threaded method. During the installation process of the connecting device, the efficiency is relatively slow. At the same time, it is also affected by the shaking or long-term vibration of the equipment, resulting in the loosening or falling off of the two active devices connected by the thread, which is likely to cause problems such as connection short circuits.

[0003] Chinese Patent CN220527308U discloses a waterproof connector that is convenient for plugging and unplugging, including a pin connection end and a jack connection end. A plugging and unplugging component is fixedly connected to the top surface of the alignment sleeve, and an installation hole is opened on the top surface of the jack connection end, and a positioning component is fixedly installed inside the installation hole. Through the cooperation of the chute and the plugging and unplugging component, the pin connection end and the jack connection end can be quickly plugged and unplugged by sliding connection. By setting the positioning component to fix the pin connection end inserted inside the jack connection end, the pin connection end can be effectively prevented from falling off. However, when the device is connected, it sometimes needs to be plugged and unplugged and debugged frequently. Although this utility model has a stable connection, it is not convenient for immediate plugging and unplugging, does not set connection gears, and cannot adapt to the equipment debugging scenario. Based on this, further improvements are needed. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a connector with a gear locking function, which has the advantages of multi-gear locking, immediate plugging and unplugging, and stable connection, so as to solve the problems of inconvenient immediate plugging and unplugging, no connection gears set, and inability to adapt to the equipment debugging scenario proposed in the above background art.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a connector with a gear locking function, comprising a male connector and a female connector, the male connector and the female connector are meshed with each other, a boss is arranged at the upper end of the male connector, a plurality of locking grooves are evenly arranged at the upper end of the boss, a rubber sheath is installed at the rear end of the male connector, a cable is installed in the rubber sheath, a connecting tube is fixed at the rear end of the female connector, a cable is arranged in the connecting tube, a primary locking piece is installed at the upper end of the female connector, and secondary limiting pieces are installed on both sides of the primary locking piece.

[0006] Preferably, a guide limit groove is provided on the side of the male connector, and a guide limit block is provided on the inner wall of the female connector. The guide limit groove and the guide limit block cooperate with each other. The front of the male connector and the female connector are provided with connecting terminals, and the connecting terminals are electrically connected to the cable.

[0007] Preferably, the primary locking member includes a locking plate, which is slidably connected to the inner wall of the female connector, and the locking plate cooperates with the locking groove. A support block is fixed to the upper end of the locking plate, an unlocking plate is provided at the front end of the support block, and a spring is provided at the upper end of the support block.

[0008] Preferably, a wedge-shaped chamfer is provided on the front side of the locking plate.

[0009] Preferably, the secondary limiting member includes a side plate and a supporting rotating plate, the side plate is provided with an arc-shaped groove, the supporting rotating plate is rotatably connected to the side wall of the primary locking member, a limiting pressure roller is fixed between the supporting rotating plates, and the limiting pressure roller cooperates with the arc-shaped groove.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows: the connector with gear locking function can lock the connection in stages. When debugging the equipment and multiple plugging and unplugging are required, only the first-level locking piece is used for locking, which has good flexibility. When a stable connection is required to avoid falling off, a second-level limit piece is used for locking, and the connection is stable. Specifically, the male connector is inserted into the female connector so that the connecting terminals at both ends are embedded in each other. During insertion, the front end of the boss contacts the wedge-shaped chamfer of the locking plate, pushing it upward. As the insertion depth increases, the locking plate is embedded in the locking groove under the pressure of the spring to achieve first-level locking. At this time, the unlocking plate is pushed upward to drive the locking plate to lift up, thereby achieving unlocking and facilitating plugging and unplugging. When second-level locking is required, the limiting pressure roller is pressed clockwise into the arc groove to lock the position of the unlocking plate to avoid changes due to vibration, and the connection stability is good.

[0021] Combined with the above structural features, when the present utility model works, it can lock the connection in gears. When debugging equipment and multiple plug-ins and unplug-ins are required, only the primary locking member 7 is used for locking, which has good flexibility. When stable connection is required to avoid detachment, the secondary limiting member 8 is used for locking, and the connection is stable. Specifically: insert the male connector 1 into the female connector 2. When inserting, the front end of the boss 3 contacts the wedge-shaped chamfer of the locking plate 71 and pushes it upward. As the insertion depth increases, the locking plate 71 is embedded into the locking groove 4 under the pressure of the spring 74 to achieve primary locking. At this time, pull up the unlocking plate 73 to drive the locking plate 71 to lift, realizing unlocking and facilitating plugging and unplugging. When secondary locking is required, press the limiting pressure roller 84 clockwise into the arc-shaped groove 82 to lock the position of the unlocking plate 73 to prevent it from changing due to vibration, and the connection stability is good.

The guiding and limiting groove 11 and the guiding and limiting block 21 cooperate with each other. Connecting terminals 12 are provided on the front surfaces of the male connector 1 and the female connector 2. The connecting terminals 12 are electrically connected to the cable;

[0023] Combined with the above structural features, when the present utility model works, the guiding and limiting groove 11 and the guiding and limiting block 21 cooperate with each other to achieve limiting and prevent the connectors from shaking. The connecting terminals 12 play a role in conducting electricity and transmitting current.

[0024] Working principle: When the present utility model is in use, the male connector 1 is inserted into the female connector 2. During insertion, the front end of the boss 3 contacts the wedge-shaped chamfer of the locking plate 71 and jacks it up. As the insertion depth increases, the locking plate 71 is embedded in the locking groove 4 under the pressure of the spring 74 to achieve primary locking. At this time, the unlocking plate 73 is toggled upward to drive the locking plate 71 to lift, realizing unlocking and facilitating insertion and extraction. When secondary locking is required, the limit pressure roller 84 is pressed clockwise into the arc-shaped groove 82 to lock the position of the unlocking plate 73 to prevent it from changing due to vibration, and the connection stability is good.
