The technical scheme protected by the utility model is specifically described below with reference to the accompanying drawings.

Referring to fig. 1 to 7, an embodiment of the present utility model provides an electrical connector, which includes an insulating base 100 and a locking collar 200.

The insulating base 100 has a post 110, a connector 120, and a pair of stop tenons. The post 110 is generally cylindrical and the connector 120 is located at one end of the post 110. The pair of stop tenons includes a first stop tenon 111 and a second stop tenon 112, the first stop tenon 111 and the second stop tenon 112 are respectively disposed on two sides of the sidewall of the column 110, and in this embodiment, the first stop tenon 111 and the second stop tenon 112 are asymmetrically disposed on the column 110. The sidewall of the column 110 is provided with a flange 130, specifically, the flange 130 is disposed at the aforementioned end of the column 110, and the flange 130 surrounds the sidewall of the column 110. And a flange 130 is disposed between the cylinder 110 and the joint 120 to separate the cylinder 110 from the joint 120.

The locking collar 200 is rotatably fitted around the cylinder 110 along the central axis of the cylinder 110, and the locking collar 200 is also movable parallel to the central axis of the cylinder 11. The locking collar 200 is also movable parallel to the central axis of the post 110 relative to the post 110 between a locking position and a release position, specifically on either side of the flange 130 along the central axis, the locking collar 200 being positioned around the fitting 120 when the locking collar 200 is in the locking position as shown in fig. 5 and 6. When the locking collar 200 is in the release position, the locking collar 200 is retracted away from the fitting 120 to facilitate the operation of the fitting 120 to plug a corresponding connector (not shown).

The inner wall of the locking collar 200 is provided with at least one locking tenon, in this embodiment, the locking collar 200 has a pair of oppositely arranged locking tenons, the pair of locking tenons comprises a first locking tenon 211 and a second locking tenon 212, when the locking collar 200 is located at the locking position as shown in fig. 5 and 6, the pair of locking tenons are respectively located at two opposite sides of the joint 120 and can enable each locking tenon to move around the joint 120 to be clamped and locked to the corresponding connector by rotating the locking collar 200. At least one opening is provided on the flange 130 corresponding to each locking tongue, and in this embodiment, a pair of openings is provided on the flange 130 corresponding to the pair of locking tongues. The pair of openings are a first opening 131 corresponding to the first locking tongue 211 and a second opening 132 corresponding to the second locking tongue 212, respectively, and each opening is respectively used for allowing the corresponding locking tongue to pass through so as to allow the locking collar 200 to move from the locking position to the releasing position or from the releasing position to the locking position.

The locking collar 200 has a pair of arcuate ribs corresponding to the pair of stop tenons, including a first arcuate rib 221 corresponding to the first stop tenon 111 and a second arcuate rib 222 corresponding to the second stop tenon 112. Specifically, the first and second arc ribs 221 and 222 are provided on both sides of the inner wall of the lock collar 200, respectively, and the first and second arc ribs 221 and 222 are asymmetrically disposed on the lock collar 200. The first arc rib 221 and the second arc rib 222 extend about the central axis of the column 110.

The locking collar 200 has a plurality of vertical walls corresponding to the arc ribs, the vertical walls include a first vertical wall 231 corresponding to the first arc rib 221 and a second vertical wall 232 corresponding to the second arc rib 222, the first vertical wall 231 is disposed at one side of the first arc rib 221, and the second vertical wall 232 is disposed at one side of the second arc rib 222.

Referring to fig. 1 to 6, when the locking collar 200 is in the locking position, each of the stopper tenons abuts against one side of the corresponding arc rib, and when the locking collar 200 is rotated in the locking position, the first stopper tenons 111 and the second stopper tenons 112 can slide along the first arc rib 221 and the second arc rib 222, respectively, thereby defining a rotational stroke of the locking collar 200. Specifically, each stop tenon is abutted against the other side of the corresponding arc rib, which is opposite to the vertical wall on the arc rib. The opposite relationship between each stop tenon and its corresponding arc rib and vertical wall is the same, and fig. 6 only illustrates the first stop tenon 111 and its corresponding first arc rib 221 and first vertical wall 231. As shown in fig. 6, the first stop tongue 111 abuts against the other side of the first arc rib 221 opposite to the first standing wall 231, and the second stop tongue 112 abuts against the other side of the second arc rib 222 opposite to the second standing wall 232.

Referring to fig. 1 and 6, the inner sidewall of the locking collar 200 is provided with a stop step 201, and the flange 130 abuts against the stop step 201 when the locking collar 200 is in the locking position. Specifically, the stop step 201 includes a plurality of concentric arc segments, the stop step 201 has a supporting surface 202, the supporting surface 202 includes a plurality of coplanar concentric arc planes, the normal direction of the supporting surface 202 is parallel to the central axis of the post 110, and the flange 130 abuts against the supporting surface 202 to fix the locking collar 200 and the insulating base 100 to each other.

Referring to fig. 6, when the locking collar 200 is in the locked position, the stop tongue abuts against the opposite side of the corresponding arcuate rib from the upstanding wall on the arcuate rib. When the connector is pulled after being matched, the vertical wall can support the corresponding arc rib to resist the lateral stress applied to the arc rib by the corresponding stop tenon caused by the pulling action, so that the arc rib is prevented from being broken.

As shown in fig. 2, 3 and 7, the locking collar 200 has a support rib 240, the support rib 240 is disposed on the inner sidewall of the locking collar 200 and the support rib 240 abuts against the outer sidewall of the cylinder 110. Since the first and second stop tenons 111 and 112 are asymmetrically disposed on the locking collar 200, the resultant force applied to the cylinder 110 is parallel to the central axis of the cylinder 110 and is biased to one side of the central axis of the cylinder 110, which may cause the cylinder 110 to be biased, and the support rib 240 is capable of fixing the cylinder 110 against the outer sidewall of the cylinder 110 to avoid the bias.

The foregoing description is only illustrative of the present utility model and is not intended to limit the scope of the utility model, and all equivalent structures or equivalent processes or direct or indirect application in other related technical fields are included in the scope of the present utility model.
