[0041] To solve the technical problems of complex structure and low installation efficiency of the connector in male-female mating installation in the prior art, an embodiment of this application provides a quick-insert self-locking connector for male-female mating. The following is a detailed elaboration.

[0042] AsFigures 1 to 6 As shown, a new type of quick - insertion self - locking connector for male - female mating includes

[0043] a first housing 1, a first insulator 41 is arranged inside the first housing 1, and a jack member 51 is fixed inside the first insulator 41;

[0044] a second housing 2, a contact member 6 is arranged inside the second housing 2, a second insulator 42 is arranged inside the contact member 6, and a pin 52 is arranged inside the second insulator 42;

[0045] a sleeve 3, one end of the sleeve 3 is sleeved on the second housing 2, and the sleeve 3 is rotationally clamped with the second housing 2; the other end of the sleeve 3 is sleeved on the first housing 1, and the sleeve 3 is screwed and locked with the second housing 2.

[0046] Specifically, as an optional implementation manner in this embodiment, as Figures 1 to 6 shown, the screw - locking structure between the sleeve 3 and the first housing 1 is:

[0047] at least two first clamping blocks 31 are arranged inside the sleeve 3;

[0048] a circumferential groove 11 and an axial retaining ring 12 are formed on the first housing 1, a pair of inner convex blocks 13 and a plurality of limiting inclined blocks 14 are arranged inside the circumferential groove 11, the inner convex blocks 13 are located on both sides of the side wall of the circumferential groove 11, the limiting inclined blocks 14 are circumferentially distributed inside the circumferential groove 11, and a plurality of bayonet openings 15 for the axial entry of the first clamping blocks 31 are formed on the side wall of the circumferential groove 11;

[0049] a spring 8 is arranged inside the circumferential groove 11, one end of the spring 8 is clamped with the two inner convex blocks 13, so that the spring 8 is installed inside the circumferential groove 11, and the other side of the spring 8 is adapted to abut against the adjacent first clamping block 31;

[0050] When the first housing 1 is connected to the sleeve 3, the first housing 1 is inserted into the sleeve 3, and each first clamping block 31 axially enters the circumferential groove 11 of the sleeve 3, then the sleeve 3 rotates, driving the first clamping block 31 to squeeze through the limiting inclined block 14, and then one of the first clamping blocks 31 compresses the spring 8, and the sleeve 3 makes a circumferential elastic rotation relative to the first housing 1 within the compression of the spring 8.

[0051] After the sleeve 3 squeezes through the limiting inclined block 14 through the first clamping block 31, the sleeve 3 and the first housing 1 are assembled together, the sleeve 3 can make a circumferential elastic rotation relative to the first housing 1, and the first clamping block 31 is located inside the circumferential groove 11, restricting the axial movement of the sleeve 3 relative to the first housing 1.

[0052] In this embodiment, the number of the first clamping blocks 31 is three. See Figure 6, the first clamping block 31 is formed as a rectangle. The number of the first clamping blocks 31 defines the circumferential rotation angle of the screw sleeve 3 relative to the first housing 1. The fewer the number, the larger the rotation angle; the more the number, the smaller the rotation angle.

[0053] Specifically, as an alternative implementation in this embodiment, as Figures 1 to 6 shown, the rotational clamping structure between the screw sleeve 3 and the second housing 2 is:

[0054] A pair of second clamping blocks 32 are arranged inside the screw sleeve 3, and a pair of L-shaped clamping grooves 21 are arranged on the second housing 2. The vertical grooves of the L-shaped clamping grooves 21 are axially opened, and the horizontal grooves of the L-shaped clamping grooves 21 are circumferentially opened;

[0055] When the second housing 2 is connected to the screw sleeve 3, first drive the screw sleeve 3 to rotate, compress the spring 8, and then the two second clamping blocks 32 first move axially along the vertical grooves of the first clamping groove, and then the screw sleeve 3 resets under the action of the spring 8, driving the second clamping blocks 32 into the horizontal grooves of the first clamping groove to realize the clamping between the screw sleeve 3 and the second housing 2.

[0056] When the screw sleeve 3 is connected to the second housing 2, the screw sleeve 3 has been connected to the first housing 1, and then the screw sleeve 3 and the second housing 2 are quickly plugged and locked.

[0057] Specifically, as an alternative implementation in this embodiment, as Figure 4 shown, a first guiding inclined surface 22 is provided on one side at the entrance of the vertical groove;

[0058] A second guiding inclined surface 23 is provided at the corner of the vertical groove and the horizontal groove.

[0059] Through the guiding inclined surfaces, it is convenient to plug and lock the screw sleeve 3 and the second housing 2.

[0060] Specifically, as an alternative implementation in this embodiment, as Figure 5 shown, the first clamping block 31 is a triangular block.

[0061] Specifically, as an alternative implementation in this embodiment, as Figure 1 shown, a sealing ring 7 is arranged on the first housing 1. When the first housing 1 is inserted into the second housing 2, the sealing ring 7 seals the first housing 1 and the second housing 2 axially.

[0062] Specifically, as an alternative implementation in this embodiment, as Figure 1 shown, a first insulating sheet 91 is arranged inside the first housing 1, and a second insulating sheet 92 is arranged inside the second housing 2.

[0063] The quick - plug self - locking connector with male - female mutual matching of the present utility model. The first housing 1 and the second housing 2 are both of hollow - hole structures. The inside of the housing is a hollow structure. The contact member 6 and the second housing are integrally formed by interference fit. The second insulator 42 is nested inside the contact member 6. The first insulator 41 is nested inside the first housing. The sealing ring 7 is sleeved on the first housing. After male - female mutual matching installation, water can be prevented from seeping in from the mutual - matching part. The spring 8 is embedded in the annular groove 11 of the first housing. The first clamping block 31 in the shape of a rectangle is inside the screw sleeve 3. After aligning with the bayonet 15 of the annular groove 11 on the first housing and then sleeving it on, the screw sleeve 3 is rotated clockwise, so that the first clamping block 31 of the screw sleeve 3 presses against the limiting inclined block 14 in the annular groove 11. Relying on the spring 8 and the limit of the first housing to realize the rotation, rebound and limit of the screw sleeve 3. At the same time, a second clamping block 32 is provided on the other side of the screw sleeve 3, which matches with the L - shaped clamping groove 21 on the outer side of the second housing. During installation, the second clamping block 32 slides into the first guiding inclined surface 22 of the vertical groove in the L - shaped clamping groove 21. Then, the screw sleeve 3 rotates under the force of the spring 8, and the second clamping block 32 enters the horizontal groove in the L - shaped clamping groove 21 for locking, and the screw sleeve 3 is locked, so as to realize the quick - plug and lock function of the connector.
