The first terminal 20 to which the first locking member 30 is fixed is inserted into the first receiving cavity 100 from the first mounting opening 12 of the first body portion 10. Since the wall surface connecting the locking protrusion 32 is a cantilever, the locking protrusion 32 is pressed by the inner wall surface of the first mounting opening 12, so that the locking protrusion can move into the limiting hole. When the locking protrusion 32 is located in the limiting hole 13, the force applied to the locking protrusion 32 by the inner wall surface of the first mounting opening 12 disappears, and at this time, the locking protrusion 32 protrudes out of the limiting hole 13 after rebounding, and is located in the limiting hole 13 at the top end in the axial direction of the first terminal base.

The locking protrusion 32 of the present application can rotate along the circumferential direction of the first body 10 in the limiting hole 13, and when the locking protrusion 32 rotates clockwise, the locking protrusion stops at the second limiting edge 131 of the first limiting hole 13; when the locking protrusion 32 rotates counterclockwise, it stops at the first position-limiting edge 130 of the first position-limiting hole 13. Therefore, the locking or unlocking between the limiting protrusion and the second connector can be realized.

The first protrusion guiding inclined plane 324 forms an obtuse angle with the first longitudinal side 321 and the outer side 320; the second protrusion guiding inclined plane 325 forms an obtuse angle with the outer side surface 320 and the second longitudinal side surface 322, respectively; the third protrusion guiding inclined surface 326 and the second longitudinal side surface 322 and the third longitudinal side surface 323 form an obtuse angle, respectively. The obtuse angle is convenient for the latch protrusion 32 to be inserted into the second connector, so that the latch protrusion can be more smoothly locked or unlocked with the second connector, hard interference is eliminated, and damage to the connector is reduced.

The guiding surface 327 is located on a side of the locking protrusion 32 away from the first mounting opening 12, and a maximum height of the guiding surface 327 relative to an outer wall surface of the cantilever 312 is smaller than a height of the outer side surface relative to the outer wall surface of the cantilever 312. So that a height difference is formed between the outer side surface 320 and the guiding surface 327 to facilitate locking of the locking protrusion and the second connector.

Reference is made to the second connector 2 shown in fig. 7-8. The second connector 2 is matched with the first connector 1, and the second connector 2 comprises a second locking piece 41 matched with the first locking piece 30; the first terminal 20 drives the first locking member 30 to rotate, so that the first locking member 30 rotates relative to the second locking member 41, thereby unlocking or locking the first connector 1 and the second connector 2.

The second locking member 41 is disposed on an inner wall surface of the second body 40 and is disposed close to the second mounting opening 401. When the first connector 1 and the second connector 2 are inserted into each other, they can interfere with the stopper projection 32 in the stopper hole provided near the first mounting opening 12 of the first connector in close proximity.

The second locking member 41 is a locking groove engaged with the locking protrusion 32, and includes an inlet groove 42 close to the second mounting opening 401, and a locking groove 43 located on a side of the inlet groove 42 away from the second mounting opening 401. A blocking protrusion 44 is arranged between the inlet slot 42 and the locking slot 43, the side surface of the blocking protrusion 44 located on the inlet slot 42 is a first guiding inclined surface 440, and the first guiding inclined surface 440 extends from the top surface of the blocking protrusion 44 to the direction close to the second mounting opening 401 in an inclined manner and is connected with the slot bottom of the inlet slot 42. The top surface of the blocking projection 44 refers to a surface of the blocking projection 44 adjacent to the third receiving chamber 400.

The locking slot 43 includes two opposing first side surfaces 430 spaced circumferentially along the second body portion 40 and two opposing second side surfaces 431 spaced axially along the second body portion 40. At least one of the first side surfaces 430 is an unlocking guide inclined surface, one side of the unlocking guide inclined surface is connected with the inner wall surface of the third accommodating cavity 400, the other side of the unlocking guide inclined surface is connected with the bottom surface of the locking groove 43, and an angle formed between the unlocking guide inclined surface and the bottom surface of the locking groove 43 is larger than 90 degrees, so that the locking protrusion 32 can be conveniently removed from the locking groove 43 to realize unlocking, or the locking protrusion 32 can be conveniently moved into the locking groove to realize locking.

A preferred embodiment may further include an unlocking groove 45, wherein the unlocking groove 45 is located at one side of the locking groove 43 and is aligned with the locking groove 43 along the circumferential direction of the second body portion 40. One side of the unlocking guide inclined plane 430 is connected with the unlocking groove 45, the other side of the unlocking guide inclined plane 430 is connected with the locking groove 43, and the depth of the unlocking groove 45 is smaller than that of the locking groove 43, so that the locking protrusion can be conveniently moved out of the locking groove or moved into the locking groove.

When the first connector and the second connector need to be unlocked, the first terminal is only required to be rotated to drive the first locking piece to slide into the unlocking groove through the unlocking guide inclined plane in the locking groove 43, so that unlocking is realized.

In a preferred embodiment, the inlet slot 42 further includes a guiding inclined plane 421 located at a side of the first guiding inclined plane 440 close to the second mounting opening 401.

When the first connector 1 is inserted into the third receiving cavity 400 of the second connector, the locking protrusion 32 is located in the entrance slot 42 and aligned with the locking slot. As the first connector moves further into the inlet slot 42, the locking function between the first connector and the second connector is achieved by the first guide slope 440 to facilitate the introduction of the locking protrusion into the locking slot 43.

In a preferred embodiment, the arc length of the limiting hole 13 of the first connector in the circumferential direction of the first body portion 10 is greater than or equal to the maximum arc length of the inlet slot 42 in the circumferential direction of the second body portion 41. The maximum arc of the inlet slot 42 in the circumferential direction of the second body portion is the total arc length of the guide ramp and the first guide ramp (as indicated by the arc length in brackets in fig. 8). This portion limits the arc length of the stop hole to, in effect, the arc length over which the stop lug 32 can rotate within the stop hole. In this embodiment, no matter the limiting protrusion is located at any position in the limiting hole, the locking function with the locking groove can be realized, or the unlocking function can be realized.

Specifically, when the first connector 1 with the first terminal 20 and the first locking member 30 assembled is assembled with the second connector with the second terminal 50 assembled, and the first mounting hole 12 of the first connector is inserted into the second mounting hole 401 of the second connector, the locking protrusion 32 protruding out of the first connector body portion can rotate in the circumferential direction of the first connector body portion in the limiting hole, and is located on the first limiting edge 130 or the second limiting edge 131 in the circumferential direction.
