Description

Technical Field

[0001] This utility model relates to the field of connector equipment technology, specifically to a connector with an automatic locking function. Background Technology

[0002] A connector is an electronic component primarily used to connect wires or cables. They provide a convenient and reliable way to connect and disconnect wires and enable the transmission of current, signals, or data. Cable connectors typically consist of two or more mating connectors, each with pins and sockets, which are used to connect and disconnect the wires through insertion and removal operations.

[0003] For example, the utility model patent disclosed in announcement number CN217281441U discloses a radio frequency signal connector with a self-locking structure, comprising: a body including a connector head and a connecting groove, a plug disposed on the inner side of the connector head, a connecting cylinder fixedly connected to the surface of the connector head, and a slot fixedly connected to the surface of the connecting groove; a self-locking mechanism including a limiting groove formed on the inner side of the connector head, a stop rod penetrating the outer surface of the connector head, a locking rod fixedly connected to the outer surface of the slot, and a locking block fixedly connected to the side of the locking rod away from the slot. This utility model achieves self-locking between the connector head and the connecting groove through the sliding connection of the locking rod and the limiting groove, and the insertion connection of the locking block and the slot. The stop block clamps and fixes the connecting wire inside the connecting cylinder, and the connection between the rotating ring and the stop block fixes the position of the stop block within the connecting cylinder.

[0004] Although the above-mentioned connectors can perform connection operations, they are not convenient for quick and easy automatic docking and locking operations, which reduces the convenience of connecting subsequent connectors and also reduces the stability of the connectors after docking. Therefore, there is an urgent need for a connector with an automatic locking function to solve the above-mentioned problems. Utility Model Content

[0026] The support device 2 is slidably engaged with the outer end face of the alignment sleeve 1, and four sets of limiting devices 4 are equidistantly engaged with the inner end face of the support device 2, and a guide slip ring 3 is slidably engaged with the outer end face of the support device 2.

[0027] The support device 2 includes a fixed card seat 21. A limiting cable 22 is provided at the center of the rear end face of the fixed card seat 21, and plugs 25 are provided at equal intervals on the inner end face of the fixed card seat 21. Four sets of fixed guide grooves 24 are provided at equal intervals on the inner wall of the fixed card seat 21, and a guide groove 23 is provided on the side end face of the fixed card seat 21 opposite to the fixed guide grooves 24.

[0028] The limiting device 4 includes a fixed guide plate 41, a supporting base plate 44 is provided at the center of the lower end face of the fixed guide plate 41, two sets of spring retaining rings 42 are provided on the upper end face of the supporting base plate 44, and three sets of snap-fit ​​sliding plates 43 are provided at equal intervals on the lower end face of the supporting base plate 44.

[0029] The guide slide plate 8 is adapted to the fixed guide groove 24, and the alignment sleeve 1 is slidably inserted into the fixed card seat 21 through the adaptation of the guide slide plate 8 and the fixed guide groove 24, which can improve the accuracy and stability of the subsequent docking of the fixed card seat 21 and the alignment sleeve 1.

[0030] The spring retainer 42 is fixedly connected to the top wall of the fixed guide groove 24, and the fixed guide plate 41 is slidably connected to the guide slide 23. The snap-fit ​​slide plate 43 is fixedly snapped into the wedge-shaped snap-fit ​​block 5. The hook setting allows the wedge-shaped snap-fit ​​block 5 to slide inward and cooperate with the inclined surface of the snap-fit ​​slide plate 43, improving the ease of entry. At the same time, the two sets of vertical wedge-shaped snap-fit ​​blocks 5 and snap-fit ​​slide plate 43 can improve the stability of subsequent locking.

[0031] The guide slip ring 3 has a fixed chamfer at the front and the guide slip ring 3 is slidably connected to the fixed guide plate 41 through the fixed chamfer.

[0032] Working principle: During use, if it is necessary to automatically align and lock the fixed bracket 21 with the alignment sleeve 1, the user can hold the fixed bracket 21 and the alignment sleeve 1 together and align them coaxially. Then, the alignment sleeve 1 is aligned into the fixed guide groove 24 through the four sets of guide slides 8 to complete the initial positioning. Then, the alignment sleeve 1 and the fixed bracket 21 are pushed to align. At this time, the wedge-shaped block 5 on the upper part of the guide slide 8 can slide and guide the plate 43 to the support base plate 44. At the lower part, the supporting base plate 44 is elastically lifted until the vertical rear walls of the three sets of wedge-shaped blocks 5 are completely limited to the vertical rear wall of the snap-fit ​​slide plate 43, thereby completing the automatic insertion. If it is necessary to separate the fixed card seat 21 from the alignment sleeve 1, the user can hold the guide slip ring 3 and then slide and press it towards the limiting device 4. At this time, the guide slip ring 3 can drive the fixed guide plate 41 to rise, thereby releasing the limitation of the snap-fit ​​slide plate 43 on the wedge-shaped blocks 5, thus completing the separation of the alignment sleeve 1 from the fixed card seat 21.
