[0031] like Figure 3 As shown, the connector assembly 10 is disposed in the first housing 211 of the housing body 21 of the housing 20, and the circuit board 12 is fixed in the first housing 211, and the plug electrical connector 11 and the plurality of cables 13 extend from opposite ends of the first housing 211 to the outside of the first housing 211. Figure 4 As shown, the second shell 212 of the shell body 21 of the shell 20 is assembled to the first shell 211 to form the shell body 21 of the shell 20. The shell body 21 has an accommodating space inside and openings at opposite ends respectively, the circuit board 12 is disposed in the accommodating space, and the plug electrical connector 11 and the plurality of cables 13 extend from the openings at opposite ends of the shell body 21 to the outside of the shell body 21 respectively.

[0032] like Figure 4As shown, the extension direction of the connector assembly 10 is defined as the X direction, and the housing 20 further includes a pair of shafts 22, a pair of first limiting portions 23, a pair of second limiting portions 24, and a pair of stoppers 25. The pair of shafts 22, the pair of first limiting portions 23, the pair of second limiting portions 24, and the pair of stoppers 25 are respectively arranged on two opposite side surfaces of the housing body 21 which are parallel to the extension direction of the connector assembly 10, the direction in which the pair of shafts 22 are connected is defined as the Y direction, and the Z direction is a direction perpendicular to both the X direction and the Y direction. The pair of shafts 22, the pair of first limiting portions 23, the pair of second limiting portions 24, and the pair of stoppers 25 of this embodiment are all convex block structures protruding from the housing body 21. A pair of shaft bodies 22, a pair of second limiting portions 24 and a pair of stopper portions 25 are all arranged on the side of the first shell 211 of the shell body 21, and the second limiting portion 24 and the stopper portion 25 are located on opposite sides of the shaft body 22 in the X direction, the distance between the second limiting portion 24 and the shaft body 22 is greater than the distance between the stopper portion 25 and the shaft body 22, and the stopper portion 25 is arranged close to the shaft body 22. A pair of first limiting portions 23 are arranged on the side of the second shell 212 of the shell body 21, and the distance between the first limiting portion 23 and the shaft body 22 in the X direction is greater than the distance between the second limiting portion 24 and the shaft body 22 in the X direction.

[0033] like Figure 5 and Figure 6 As shown, Figure 6 for Figure 5 The locking member 30 is a partially exploded view of the locking member and the housing member. The locking member 30 has a pair of connecting parts 31, a pair of third limiting parts 32 and a locking part 33. The pair of connecting parts 31 are in a semicircular arc shape, and each connecting part 31 surrounds a shaft body 22 to form an abutment and the connecting part 31 extends through between the stopper 25 and the shaft body 22. Each shaft body 22 has a long axis end 221 and a short axis end 222. The diameter D of each connecting part 31 is greater than the size FS of the short axis end 222 and smaller than the size FL of the long axis end 221. When the connecting part 31 is installed on the shaft body 22, the joint between the connecting part 31 and the long axis end 221 is deformed to clamp the long axis end 221, so that the connecting part 31 is fixed to the shaft body 22.

[0034] A pair of third limiting portions 32 are connected to a pair of connecting portions 31, and each third limiting portion 32 is a long rod-shaped structure. When the connecting portion 31 is fixed to the shaft body 22, the third limiting portion 32 extends through the first limiting portion 23 and the second limiting portion 24 of the housing 20 and abuts against the first limiting portion 23. The first limiting portion 23 has an abutting plane 231 and an arcuate surface 232 connected to the abutting plane 231, and the third limiting portion 32 of the lock member 30 abuts against the abutting plane 231.

Figure 7 As shown, when the locking type electrical connector 1 of this embodiment is connected to the socket electrical connector 5 provided in the electronic device, the locking portion 33 of the locking member 30 abuts against one end of the socket electrical connector 5 to form a lock. Figure 8 As shown, when the locking type electrical connector 1 of this embodiment needs to be separated from the socket electrical connector 5 in the electronic device, the user pushes the locking portion 33 to apply force to the locking portion 33, thereby generating stress deformation at the connection between the third limiting portion 32 and the connecting portion 31, so that the locking portion 33 is separated from the socket electrical connector 5, and then the locking type electrical connector 1 of this embodiment can be separated from the socket electrical connector 5.

[0037] Although the housing member of the present embodiment includes a pair of shafts, a pair of first limiting portions, a pair of second limiting portions and a pair of stop portions, and the locking member has a pair of connecting portions and a pair of third limiting portions, the present application is not limited thereto. In other embodiments, the housing member includes a shaft, a first limiting portion, a second limiting portion and a stop portion. A shaft, a first limiting portion, a second limiting portion and a stop portion are arranged on one side of the housing member body. The connecting portion is fixed to the shaft, the third limiting portion is connected to the connecting portion, and one end of the locking member is connected to the third limiting portion and is orthogonal to the third limiting portion. In this way, the locking member can still abut against one end of the socket electrical connector to form a lock.

[0038] The locking type electrical connector of the present application is fixed to the shaft of the housing by the connection part of the locking member, and the locking part of the locking member generates stress deformation when subjected to force, so that the locking part moves within a certain stroke, thereby achieving the effect of locking and unlocking. Since the moving stroke generated by the overstress deformation of the locking part is limited, it can be applied to the limited operating space in thin electronic devices.

[0039] The above embodiments are merely illustrative of the principles and effects of the present application and are not intended to limit the present application. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present application. Therefore, all equivalent modifications or changes made by a person of ordinary skill in the art without departing from the spirit and technical ideas disclosed in the present application shall still be covered by the claims of the present application.
