Therefore, when the male end is inserted into the female end, and the cylindrical positioning portion 12 abuts against the limiting shoulder 150, the sealing member seals the abutting gap between the cylindrical positioning portion 12 and the limiting shoulder 150, so that external dust or splash water is prevented from entering the installation through hole through the abutting gap, and the electrical connection relationship between the contact pin 19 and the insertion hole 17 is not affected by the external water environment.

In the alternative of this embodiment, the connecting sleeve 13 is sleeved outside the male end, the inner peripheral side wall of the connecting sleeve 13 is provided with a slot, a limit stop block 185 is arranged in the slot, and the limit stop block 185 is connected with the connecting sleeve 13.

Specifically, the opening of the slot is opened on the end surface of the head of the connecting sleeve 13, the slot includes a first slot wall 180, a second slot wall 184 and a slot bottom 183, the slot bottom 183 faces the opening, and the first slot wall 180 and the second slot wall 184 are oppositely arranged along the circumferential direction of the connecting sleeve 13 at intervals.

A limit stop 185 is provided in the card slot to regionalize the space of the card slot. A rotary buckling groove part 182 is formed between the limit stop block 185 and the groove bottom 183 of the clamping groove, a straight inserting groove part 181 is formed between the limit stop block 185, the rotary buckling groove part 182 and one side wall (a second groove wall 184) of the clamping groove along the circumferential direction of the connecting sleeve 13, and the straight inserting groove part 181 is communicated with the rotary buckling groove part 182.

Specifically, the limit stop block 185 is connected with the second groove wall 184, so that the limit stop block 185 and the first groove wall 180 are arranged at intervals along the circumferential direction of the connecting sleeve 13, and the straight insertion groove portion 181 is formed between the first groove wall 180, the groove bottom 183, the limit stop block 185 and the thread turning groove portion 182.

The connecting buckle 11 includes a buckle member 110, the buckle member 110 includes a latch 1100 and a rotation boss 1101, the rotation boss 1101 is disposed on an outer side wall of a head portion of the latch 1100, the outer side wall of the latch 1100 is along a radial direction of the second positioning member 15, and the latch 1100 deviates from a side wall of the second positioning member 15.

The fastening member 110 can be inserted into the straight slot portion 181, the rotation-fastening boss 1101 can be rotated into the rotation-fastening slot portion 182, when the rotation-fastening boss 1101 is rotated into the rotation-fastening slot portion 182, the rotation-fastening boss 1101 is fastened in the rotation-fastening slot portion 182, and the fastening tongue 1100 faces the limit stop block 185.

Optionally, the protrusion thickness of the rotation boss 1101 is the same as the protrusion thickness of the limit stopper 185, so that the latch 1100 fits with the inner peripheral side wall of the limit stopper 185 in a state where the rotation boss 1101 is latched in the rotation slot portion 182.

Alternatively, the inner circumferential sidewall of the limit stopper 185 is offset to the outside of the connection sleeve 13 by a predetermined distance, which is equal to the thickness of the latch 1100, with respect to the inner circumferential sidewall of the connection sleeve 13, so that the inner circumferential sidewall of the latch 1100 is flush with the inner circumferential sidewall of the connection sleeve 13 when the outer circumferential sidewall of the latch 1100 is fitted with the inner circumferential sidewall of the limit stopper 185.

In this embodiment, the number of the slots is multiple, and the multiple slots are sequentially arranged at intervals along the circumferential direction of the connecting sleeve 13; the number of the snap members 110 is plural, and the plural snap members 110 are sequentially arranged at intervals in the circumferential direction of the fixing ring 111.

A plurality of buckle component 110 and a plurality of slot one-to-one ground set up to public end and female end form many places through a plurality of buckle component 110 and a plurality of slot and revolve the knot formula and directly insert fixedly, can improve the connection steadiness of the straight plug connector 1 of formula of revolving knot formula, the pine phenomenon of taking off appears after avoiding pegging graft.

Optionally, in order to compromise the stability of the connection sleeve 13 and the connection buckle 11 for inserting and fixing and reasonably simplify the structure, the number of the buckle members 110 and the number of the slots are two.

In an alternative of this embodiment, the surface of the limit stop 185 facing the slot bottom 183 of the slot includes a first surface and a second surface, and the first surface is spaced from the slot bottom 183 of the slot by a distance less than the second surface is spaced from the slot bottom 183 of the slot. In other words, the first surface is spaced from the slot bottom 183 of the slot by a first spacing distance, the second surface is spaced from the slot bottom 183 of the slot by a second spacing distance, and the first spacing distance is less than the second spacing distance.

A guide rail groove section 1820 is formed between the first surface and the groove bottom 183 of the clamping groove, a locking groove section 1821 is formed between the second surface and the groove bottom 183 of the clamping groove, the turn-buckle groove section 182 comprises the locking groove section 1821 and the guide rail groove section 1820, and the size of the guide rail groove section 1820 in the plugging direction is smaller than the size of the locking groove section 1821 in the plugging direction because the first spacing distance is smaller than the second spacing distance.

As shown in fig. 6, the locking groove 1821 is connected to the straight slot portion 181 through the guiding groove 1820, a boundary between the locking groove 1821 and the guiding groove 1820 and a boundary between the straight slot portion 181 and the guiding groove 1820 are generally indicated by dashed lines, and the locking groove 1821 is adapted to the rotation protrusion 1101 along the inserting direction, so that during the use of the rotation type straight plug-in connector 1, the connecting buckle 11 is inserted straight into the straight slot portion 181, and then the female end is rotated towards the side of the rotation groove 182, so that the rotation protrusion 1101 is rotated into the guiding groove 1820, and the female end is rotated further along the guiding groove 1820, so that the rotation protrusion 1101 is rotated into the locking groove 1821.
