Description

Technical Field

[0001] The utility model relates to the technical field of connector equipment, in particular to a connector which is convenient for docking and positioning. Background Art

[0002] The main functions of cable connectors include physical connection, electrical connection, insulation and protection. Physical connection ensures a firm connection between the pin and the socket to prevent loosening or falling off. Electrical connection is the main purpose of the connector to achieve the transmission of current, signals or data. Insulation and protection measures are used to prevent electrical short circuits and protect the connector from the external environment.

[0003] For example, the utility model patent disclosed in the publication number CN217902110U is a fiber optic connector that is easy to position, including a connecting pipe and a mounting plate. The connecting pipe is inserted into the mounting plate, wherein the smooth surface of the connecting pipe presses against the limiting surface of the mounting hole, so that the position of the mounting plate on the connecting pipe is fixed. The fastener is then threadedly connected to the connecting pipe, and one end of the fastener presses against one side of the mounting plate, so that the mounting plate is difficult to move along the axial direction of the connecting pipe, thereby improving the installation stability of the fiber optic connector.

[0004] Although the above connector can perform docking and positioning operations, it is not convenient to quickly disassemble the connector, which reduces the convenience of subsequent practical use of the connector. Therefore, a connector that is convenient for docking and positioning is urgently needed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 The utility model provides an embodiment: a connector that is easy to dock and position, including a plug housing 7 for connection, a fixed cable 4 is arranged at the center of the lower end surface of the plug housing 7, and positioning sleeves 1 are arranged at the four corners of the front end surface of the plug housing 7.

[0024] Positioning guide grooves 5, which are symmetrically arranged on the inner end surface of the plug housing 7, and plug-in slide grooves 6 are arranged at the upper and lower parts of the plug housing 7, facing the positioning guide grooves 5;

[0025] The limiting device 3 is elastically slidably engaged in the interior of the plug housing 7 by inserting the slide groove 6;

[0026] The docking device 2 is fixedly connected to the inner end surface of the plug housing 7 through the limiting device 3.

[0027] The docking device 2 includes an insulating guard plate 22, a positioning cable 21 is arranged at the center of the rear end face of the insulating guard plate 22, and plug-in guide shafts 23 are arranged at the four corners of the front end face of the insulating guard plate 22, a socket shell 26 is arranged at the center of the front end face of the insulating guard plate 22, and two groups of positioning blocks 25 are slidably connected at the inner end face of the insulating guard plate 22 near the side, and alignment slots 24 are opened at the upper and lower parts of the positioning blocks 25, and the rear part of the positioning block 25 is fixedly connected to the front part of the insulating guard plate 22 through a reset spring 27.

[0028] The limiting device 3 includes a plug-in slide shaft 34 , a fixed handle 31 is arranged at the center of the upper end surface of the plug-in slide shaft 34 , a spring clamp 32 is arranged at the bottom of the top end surface of the plug-in slide shaft 34 , and a connecting fillet 33 is opened at the bottom of the plug-in slide shaft 34 .

[0029] The socket housing 26 is adapted to the positioning socket 1 through the plug-in guide shaft 23 and then slidably plugged with the plug housing 7, which can effectively improve the accuracy of subsequent docking and limiting of the socket housing 26 and the plug housing 7.

[0030] The bottom of the spring retaining ring 32 is fixedly connected to the inner wall of the plug-in slide groove 6, and the positioning block 25 is slidably inserted into the plug housing 7 through the positioning guide groove 5. The spring retaining ring 32 can provide a sufficient elastic guiding basis for the plug-in slide shaft 34, thereby improving the stability of the subsequent plug-in slide shaft 34 limiting the positioning block 25.

[0031] The plug-in slide shaft 34 is fixedly plugged with the positioning block 25 through the alignment slot 24 . The plug-in slide shaft 34 can be plugged into the positioning block 25 through the alignment slot 24 , thereby improving the stability of the subsequent locking of the docking device 2 and the plug housing 7 .

[0032] Working principle: When in use, if it is necessary to dock the plug housing 7 and the socket housing 26, the user can first align the positioning sleeve 1 to the outside of the plug guide shaft 23. The sliding limit of the four sets of positioning sleeves 1 and the four sets of plug guide shafts 23 can effectively improve the accuracy of docking the plug housing 7 and the socket housing 26. At the same time, when the plug housing 7 and the socket housing 26 are close to each other, the positioning block 25 can be plugged into the inside of the positioning guide groove 5. At this time, the positioning block 25 can drive the two sets of plug slide shafts 3 through the connection fillet 33. 4 elastically moves outward, so that the positioning block 25 can be completely limited to the inside of the positioning guide groove 5. When the positioning block 25 moves to the limit, the upper and lower groups of plug-in slide shafts 34 can be automatically plugged into the inside of the alignment slot 24 under the elastic reset of the spring clamp ring 32 to complete the automatic locking. At the same time, the reset spring 27 is in a tight state at this time, which can facilitate the subsequent user to pull the plug-in slide shaft 34 outward through the fixed handle 31 to release the positioning block 25 from being limited, and provide sufficient elastic force for the separation of the socket housing 26 and the plug housing 7.
