Detailed Description

Embodiments of the present utility model are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model. In the description of the present utility model, it should be understood that the directions or positional relationships indicated by the terms "upper", "lower", "front", "upper surface", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the apparatus or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present utility model.

Referring to fig. 1-4, an embodiment of the present utility model is provided: a novel elbow connector comprises a plug 1 and a socket 3; a connection terminal 2 is arranged in the plug 1, and the connection terminal 2 is connected with an electric conductor in the plug 1; an electrode 4 is arranged on the socket 3, one end of the electrode 4 is provided with a jack 7, and the electrode is connected with a plug pin 20 arranged on the connecting terminal 2 through the jack 7 so as to realize the conduction of a circuit between the plug 1 and the socket 3; the bolt 20 is provided with a first annular groove 23, and the first annular groove 23 is connected with a first bulge 6 arranged in the jack 7 in an adaptive manner; the first ring groove 23 is further provided with a second protrusion 22 facing the insertion hole 7, and after the second protrusion 22 enters the insertion hole 7, the outer wall surface of the second protrusion 22 is attached to the inner wall surface of the second ring groove 5 in the insertion hole 7.

After the electrode 4 is contacted with the connecting terminal 2, the connection between the electrode 4 and the connecting terminal is more stable and reliable under the action of the two ring grooves and the two protrusions; secondly, the electrode 4 can rotate along the connecting terminal, so that the connector can adapt to the trend of the wire harness;

in addition, under the mutual matching of the two ring grooves and the two protrusions, the plug 1 is more stable after being connected with the socket 3, and the problem that the plug 1 is separated from the socket 3 due to false touch is solved.

Further, since the connecting terminal 2 is further provided with the notch 21, and the second protrusion 22 is bisected by the notch 21, after the plug 20 enters the jack 7, the notch 21 can be close to each other under the action of the jack 7, so that the electrode 4 can be conveniently inserted into the connecting terminal 2.

In summary, the notch 21 is provided, when the plug 1 needs to be pulled out, the plug 1 is pulled by force, and the second protrusion 22 on the plug 20 moves in opposite directions after being stressed, so that the diameter of the plug 20 becomes smaller, so as to facilitate the separation of the plug 1 and the socket 3.

Based on the above, the connector can not only improve the stability of connection between the plug 1 and the socket 3, but also facilitate the plug 1 to be pulled out from the socket 3 when in use.

On the basis of the above scheme, because the electrode 4 is provided with the limiting ring 40, and the limiting ring 40 is connected with the limiting plate 30 arranged inside the socket 3, the electrode 4 is reliably positioned in the socket 3 under the action of the limiting ring 40 and the limiting plate 30 after the electrode 4 and the socket 3 are installed, and the stability of the electrode 4 after being connected with the socket 3 is further improved.

In addition, the limiting plate 30 is arranged in a shape of a circular truncated cone, and strip-shaped grooves are uniformly formed in the circumferential surface of the limiting plate 30, and one end facing the electrode 4 is folded towards one end far away from the electrode 4, so that the difficulty in separating the electrode 4 from the socket 3 is improved under the action of the circular truncated cone-shaped limiting plate 30 after the electrode 4 is inserted, and the electrode 4 is connected with the socket 3 more stably.

Further, the electrode 4 is further provided with a mounting groove 41 for mounting a sealing ring, and an inclined plane is formed between the mounting groove 41 and the limiting ring 40, so that the electrode 4 can smoothly enter the socket 3 and simultaneously can seal a gap at the joint of the electrode 4 and the socket 3 by using the sealing ring, thereby improving the waterproof capability of the device.

Further, since the surface of the second protrusion 22 facing the insertion hole 7 is also provided with an inclined surface, the plug 20 can be inserted into the insertion hole 7 more smoothly.

The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings, but the present utility model is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the utility model, and yet fall within the scope of the utility model.
