Meanwhile, it should be understood that the sizes of the respective portions shown in the drawings are not drawn in an actual proportional relationship for the convenience of description. Techniques, methods, and apparatus known to those of ordinary skill in the relevant art may not be discussed in detail but are intended to be part of the specification where appropriate. In all examples shown and discussed herein, any particular value should be construed as merely illustrative, and not limiting. Thus, other examples of the exemplary embodiments may have different values. It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.

Spatially relative terms, such as "above … …," "above … …," "above … …," "above," and the like, may be used herein for ease of description to describe one device or feature's spatial relationship to another device or feature as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures.

The device may be otherwise variously oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

As shown in fig. 1, a connector according to an embodiment of the present invention includes:

the connector comprises a connector shell 1, a locking piece and a locking piece, wherein the connector shell 1 is provided with a jack 11, and the end surface of the connector shell 1 is provided with the locking piece;

the wire harness connection end 2 includes an insertion portion 21 and a locking piece provided on one side of the insertion portion 21, the insertion portion 21 rotates in a first direction to be screwed with the insertion hole 11, and the locking piece abuts against the locking piece to prevent the insertion portion from rotating in a second direction opposite to the first direction.

The utility model discloses the connector is through setting up the locking piece on the terminal surface of connector housing 1 and set up the card fastener on the pencil connecting end, thereby insert 21 when rotatory and with jack threaded connection along the first direction, thereby card fastener and locking piece butt make the unable rotatory connector of avoiding appearing becoming flexible along the second direction of insert, compare with prior art, the reliability is higher.

Specifically, the locking member of the present embodiment includes a boss 12, a counter bore is disposed on the connector housing 1, and the boss 12 is telescopically disposed in the counter bore. After the insertion portion 21 is inserted into the insertion hole 11, the boss 12 may be manually pressed into the counterbore and then the insertion portion may be rotated in the second direction to detach the harness connection end from the connector housing.

In the present embodiment in particular, the boss 12 is connected to the bottom of the counterbore by an elastic member. The elastic piece is arranged so that the boss 12 automatically pops out of the outer side of the counter bore when not pressed, and therefore the boss is abutted to the clamping stop piece to play a role in preventing looseness. Also, the boss 12 of this embodiment is connected to the connector housing to prevent loss.

The elastic member may be a spring.

In the present embodiment, as shown in fig. 1, the connector includes two bosses 12 provided on the end face at an interval.

As shown in fig. 1, the boss 12 of the present embodiment has an inclined surface, and the distance between the inclined surface and the end surface gradually increases in the first direction. Then the boss 12 may retract into the counterbore under pressure as the insert 21 is rotated in the first direction; after the insertion portion 21 is rotated over the boss 12, the boss 12 is sprung up by the spring, so that the wire harness connection end can be rotated only in the first direction.

The boss 12 of the present embodiment has a right-angled triangle cross-sectional shape. The catch may gradually press the boss 12 into the counterbore as the insert is rotated in the first direction. When the insert portion is rotated past the boss 12, the boss may again abut the retainer to prevent rotation of the insert portion in the second direction.

As shown in fig. 1, the wire harness connection end of the present embodiment includes an annular sleeve 22 provided on the insertion portion 21 side and abutting against the end face, and a locking plate 23 provided on the outer surface of the annular sleeve 22.

The connector housing 1 of the present embodiment is a plastic housing.

As shown in fig. 1, the wire harness connection end 2 of the present embodiment further includes a tapered sleeve, and a small-diameter end of the tapered sleeve is used for connecting the wire harness 3.

Specifically, in the present embodiment, the wire harness connection end 2 is connected to the wire harness 3; the insertion portion 21 is inserted into the insertion hole 11 of the connector housing 1, and rotated clockwise so that the insertion portion 21 is threadedly connected with the insertion hole 11. The connector housing 1 of the present embodiment is provided with two bosses 12, and the bosses 12 have inclined surfaces. And the boss 12 is connected to the inside of the counter bore of the connector housing 1 by a spring. During the clockwise rotation of the harness connection end 2, the boss 12 is pressed into the counterbore by the pressing action of the stop plate 23. After the stop plate 23 rotates the boss 12, the boss 12 bounces under the action of the spring, so that the wire harness connecting end is prevented from rotating along the anticlockwise direction, and therefore the wire harness connecting end of the embodiment can only rotate along the clockwise direction to avoid loosening.

Moreover, the harness connecting end of the present embodiment cannot be rotated any more after being rotated to the position abutting against the boss 12, which indicates that the harness connecting end is connected in place, so the boss 12 of the present embodiment also plays a role in positioning.

When dismantling, the manual boss that will both sides is pushed down, and pencil link anticlockwise rotation can be dismantled.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention and not to limit it; although the present invention has been described in detail with reference to preferred embodiments, it should be understood by those skilled in the art that: the invention can be modified or equivalent substituted for some technical features; without departing from the spirit of the present invention, it should be understood that the scope of the claims is intended to cover all such modifications and variations.
