Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a special-shaped connector. Background Art

[0002] Connectors are primarily used to connect multiple components and transmit the required signals between devices or systems. Connectors are widely used in various fields, but in some special fields, such as aerospace equipment, the operating environment is relatively special, such as high or low temperatures or vibration environments, so the requirements for connectors are also more stringent. Existing connectors are generally circular or rectangular structures. Due to their inherent structure, they are prone to loose connections in low or high temperatures or vibration environments, resulting in the inability to connect between devices. They can no longer meet the requirements of use in special environments and can even cause equipment failures. Utility Model Content

[0003] The technical problem to be solved by the present invention is: in order to solve the problem that the existing connectors are generally circular, rectangular and other structural connections, and due to their own structure, they are easily loosened in the environment of too low temperature or too high temperature, or vibration, resulting in the phenomenon that the devices cannot be connected, which can no longer meet the needs of use in special environments and may even cause equipment failures. A special-shaped connector is now provided.

[0004] The technical solution adopted by the present invention to solve its technical problems is: a special-shaped connector, including a body of a cylindrical structure, a connecting end provided at one end of the body, a clamping groove provided at the end of the connecting end away from the body for preventing the body from rotating, a fixing groove provided on the body for fixing cables and cooperating with equipment, the fixing groove is provided along the radial direction of the body, a limiting mechanism for limiting the displacement of the cable is provided in the fixing groove, and a fixing mechanism for fixing the cable to the body is provided on the body. Compared with the existing technology, this solution provides a fixing groove on the body of a cylindrical structure, which is used to place cables on the one hand and to cooperate with the connecting equipment on the other hand, so as to achieve the matching and clamping of the body, and the clamping groove and the fixing groove can also prevent the body from rotating, ensuring that the connection of the body is stable and reliable, and the limiting mechanism further limits the displacement of the connecting cable, ensuring that the cable is fixed stably and reliably.

[0005] In order to realize the limiting mechanism, some embodiments are preferred, wherein the limiting mechanism includes a protrusion provided in the fixing groove, and the protrusion is provided at one end of the fixing groove along its axial direction. By providing a protrusion at one end of the fixing groove, the protrusion cooperates with the cable connection end to limit the displacement of the cable.

[0006] In order to better ensure the restriction of the cable, in some preferred embodiments, the cross-sectional area of ​​the protrusion gradually decreases from one end of the inner side of the body to the other end.

[0007] In some preferred embodiments, both radial sides of the protrusion along the main body are inwardly concave arc surfaces.

[0008] In some preferred embodiments, protrusions are provided at both ends of the fixing groove.

[0009] In some preferred embodiments, the fixing mechanism includes a countersunk hole provided on the body, the countersunk hole is provided to penetrate the body radially, and the countersunk hole and the fixing groove are provided to intersect with each other.

[0010] In order to facilitate the processing of the fixing mechanism, in some preferred embodiments, the countersunk hole and the fixing slot are arranged perpendicular to each other. By setting the countersunk hole and the fixing slot perpendicularly, the processing of the hole on the device is facilitated, and the production efficiency of the device is improved.

[0011] In some preferred embodiments, the body is a stepped shaft, and the connecting end is arranged at the small end of the stepped shaft.

[0012] In order to facilitate the operation of the body, some embodiments preferably have a blind hole for engaging with an external tool on the outer peripheral surface of the body away from the connection end. The blind hole is provided on the body, and the blind hole can engage with the external tool, thereby increasing the operability of the body and being suitable for realizing automated assembly.

[0013] In order to facilitate the installation of the body, in some preferred embodiments, the end of the body away from the connection end is provided with knurling. By providing the knurling on the body, the knurling increases the friction when in contact with the body, ensuring stable and reliable installation of the body.

[0014] The beneficial effects of the present invention are as follows: when the special-shaped connector of the present invention is in use, a fixing groove is opened on the main body of the cylindrical structure. The fixing groove is used to place the cable on the one hand, and to cooperate with the connecting device on the other hand to achieve the cooperation and clamping of the main body. The clamping groove and the fixing groove can also prevent the main body from rotating, ensuring that the connection of the main body is stable and reliable. The limiting mechanism further limits the displacement of the connecting cable, ensuring that the cable is fixed stably and reliably, avoiding the problem that the existing connectors are generally circular, rectangular and other structural connections. Due to their own structure, the connection is easily loosened in an environment with too low or too high temperature or vibration, resulting in the phenomenon that the devices cannot be connected, which can no longer meet the use in special environments. In severe cases, it may cause equipment failure. BRIEF DESCRIPTION OF THE DRAWINGS
