As shown in fig. 1 to 5, fig. 1 to 5 disclose a plug self-locking connector with a locking function, which includes a first housing 100, a second housing 110, a core fixing member 120, a wire clamp 130 and a tail cap 140; the needle core fixing piece 120 is provided with a plurality of contact pins 121, the needle core fixing piece 120 and the wire clamp 130 are both arranged in the second shell 110, the first shell 100 is sleeved on the second shell 110, one end of the second shell 110 is provided with a lantern ring 111, and the other end of the second shell is connected with the tail cap 140; the locking piece 150 is arranged between the first shell 100 and the tail cap 140, and is connected with the other end of the second shell 110; the locking member 150 is used to position the first housing 100.

It is understood that one end of the second outer shell 110 is used for connecting with a mating connector, and the other end of the second outer shell 110 is used for connecting with a cable; when the connector is connected with a mating connector, the first housing 100 needs a certain movable space on the second housing 110, and after the connector is connected with the mating connector, if the movable space of the first housing 100 is not compressed or the first housing 100 is directly fixed, the risk of unstable connection or direct falling off exists.

In some embodiments, the lock stop 150 is a nut 151; specifically, the other end of the second housing 110 is provided with an external thread, the length of the external thread is greater than the length of the internal thread of the tail cap 140, that is, after the tail cap 140 is screwed with the second housing 110, the second housing 110 has a section of thread outside the first housing 100, a nut 151 is screwed on the second housing 110 and located between the first housing 100 and the tail cap 140, when the nut 151 is loosened, the first housing 100 has a predetermined movable space on the second housing 110, the connector can be connected with a mating connector, when the nut 151 is screwed toward the first housing 100, the movable space of the first housing 100 is compressed, when the nut 151 is screwed, an end face of the nut 151 abuts against an end face of the first housing 100, the first housing 100 is fixed, and when the movable space of the first housing 100 is smaller than a predetermined value, or directly fixes the first housing 100, the connector and the mating connector are not separated, so that the connection is stable and the signal transmission is stable.

It can be understood that the locking member is the nut 151, which is only one of the solutions with low processing difficulty, low processing cost, convenient operation and easy implementation; as shown in fig. 4, the locking member may further include a groove disposed on an outer side wall of the other end of the second housing 110, a telescopic member 152 disposed in the groove, a protrusion 153 disposed at a free end of the telescopic member 152, and a first detent 112 and a second detent 113 disposed on the second housing 110, wherein when the protrusion 153 of the telescopic member 152 is engaged with the first detent 112, the first housing 100 has a predetermined moving space on the second housing 110, and when the protrusion 153 of the telescopic member 152 is engaged with the second detent 113, the moving space of the first housing 100 on the second housing 110 is reduced or eliminated, so that the purpose of connecting the connector and the mating connector stably can be achieved.

It can be understood that, the free end of the wire clamp 130 is provided with a plurality of gaps on the wire clamp 130, the free end is compressed inwards to achieve the purpose of clamping the wire harness, the inward compression of the free end is that the inclined plane arranged on the inner side wall of the tail cap 140 is abutted against the inclined plane of the free end of the wire clamp 130, and the tail cap 140 is screwed tightly, so that the compression of the free end of the wire clamp 130 is smaller, and the purpose of fixing the wire harness is achieved; to prevent the wire clamp 130 from being compressed too much to cause the wire clamp 130 to break; in some embodiments, an elastic member 160 is further disposed in the second housing 110, and the elastic member 160 is disposed between the core fixing member 120 and the wire clip 130; when the wire clip 130 is compressed, the elastic member 160 is also compressed, and tension is provided to the wire clip 130 in real time after the elastic member 160 is compressed, so that the wire clip 130 can be prevented from being broken, and the wire clip 130 can fix the wire harness more stably by the tension of the elastic member 160.

In some embodiments, a steel ring 170 is further disposed in the second housing 110, and the steel ring 170 is located at an end of the elastic member 160 facing away from the wire clip 130.
