The electric connector is reliable in connection, convenient for prefabricating the wire harness and maintainable and replaceable, and is widely applied in various fields. With the rapid development of society, the modern industry places higher demands on the electrical connection of electrical devices or systems, particularly in terms of reliability. According to the design concept of the conventional electrical connector, generally speaking, the higher and higher reliability is accompanied by the more and more complicated structure design, which has negative effects on the cost, the appearance, the weight control and the like of the electrical connector.

For some connectors with special use environments, different position adjustment needs to be performed on the wire outlet end of the connector, and a conventional connector structure is generally characterized in that a socket is fixedly connected with a plug and does not have a position adjustment function. In order to realize the position adjusting function, a technician designs a rotatable socket, but the socket and the rotating shaft adopt stepless rotation, and the socket can rotate only by being stressed. However, this structure is not very stable and reliable, and is not practical for a large-current connector.

Detailed Description

All of the features disclosed in this specification, or all of the steps in any method or process so disclosed, may be combined in any combination, except combinations of features and/or steps that are mutually exclusive.

Any feature disclosed in this specification (including any accompanying claims, abstract and drawings), may be replaced by alternative features serving equivalent or similar purposes, unless expressly stated otherwise. That is, unless expressly stated otherwise, each feature is only an example of a generic series of equivalent or similar features.

As shown in fig. 1, which is a schematic structural diagram of the present embodiment, the connector mainly includes four parts, an upper housing 1, an elastic member 2, a locking member 3 and a base 4, and the housing 1 is rotatable with respect to the base 4.

In this embodiment, the main purpose of realizing is based on base and last casing that can rotate, still must ensure simultaneously and go up the unlimited rotation that can not between casing and the base, avoids winding the fracture with inside cable. To achieve these objectives, the present embodiment provides three improvements over existing connectors.

As shown in fig. 2, the connecting end of the upper housing is a cylindrical structure, and includes an inner connecting end with a cylindrical inner portion and an outer connecting end disposed outside the inner connecting end, and the inner and outer connecting ends are integrated. The outer wall surface of the inner connecting end is provided with threads for being in threaded connection with locking, the end surface of the outer connecting end is provided with a plurality of convex teeth 5 which are uniformly arranged along the circumferential direction, the outer connecting end is provided with a convex key 6 along the axial direction, and the key 6 is used for limiting.

As shown in fig. 3, the base is a schematic structural diagram, the base is a cylindrical structure, the inner wall of the cylinder is a smooth wall surface and is used for contacting with the outer wall surface of the locking member, and a plurality of concave teeth 7 are arranged on the end surface of the base connected with the upper shell along the circumferential direction. A protruding step is arranged in the barrel of the base along the diameter direction and used for limiting an elastic structure. The outer wall surface of the cylinder of the base is provided with a plurality of protruding strip-shaped structures, wherein part of the strip-shaped structures are obviously shorter than the adjacent strip-shaped structures, the short space is used for being matched with the key 6 on the upper shell, the short strip-shaped structures are the limit keys 8, and the sum of the length of the limit keys 8 and the length of the key 6 cannot exceed that of other strip-shaped structures. Thereby realizing the limit of the base in the rotating process.

When base, retaining member and last casing are connected as an organic whole, be provided with the elastic component between these three, the closed loop elastic component that the elastic component adopted end to end connection, exert elasticity on the base through the elastic component.

The structural installation sequence of each part of the embodiment is as follows: firstly, a base 4 is sleeved on an inner connecting end of an upper shell 1, concave teeth on the end face of the base are matched with convex teeth on an outer connecting end of the upper shell, then an elastic piece 2 is sleeved on the inner connecting end of the upper shell in a ring mode, the elastic piece 2 abuts against an inner convex step of the base, finally a locking piece 3 is sleeved on the inner connecting end of the upper shell 1 in a threaded connection mode, the end face of the locking piece abuts against the elastic piece 2, and the outer wall face of the locking piece is in contact with the inner wall face of the base.

The using method of the embodiment comprises the following steps: when the base and the upper shell need to be rotated, the base or the upper shell is fixed, the upper shell or the base is pulled, so that the concave teeth of the base and the convex teeth of the upper shell are separated from each other, and then the base or the upper shell are rotated mutually; after the base and the upper shell are rotated to the designated position, the base or the upper shell is loosened, the elastic piece recovers, and the elastic extrusion force is applied to extrude the concave teeth of the base and the convex teeth of the upper shell to be combined with each other again.

In order to realize smooth operation in the rotating process, the structures of the convex teeth and the concave teeth can not adopt regular square and cuboid structures, the convex teeth and the concave teeth preferably adopt trapezoidal structures or other structures with inclined planes, the corners of the tooth surfaces of the convex teeth and the concave teeth can not be right angles, generally adopt obtuse angles, and preferably adopt arc-shaped round angles. This kind of project organization can avoid adopting the right angle or because convex tooth and concave tooth are when the cuboid, can't rotate after both cooperations, because its contact surface of regular cuboid is plane and plane contact, does not have the excessive face of atress, probably leads to its resistance too big, unable rotation.

The invention is not limited to the foregoing embodiments. The invention extends to any novel feature or any novel combination of features disclosed in this specification and any novel method or process steps or any novel combination of features disclosed.
