The structure mainly adopts mechanical connection assembly such as shell, connecting nut, cup-shaped tube, tail clip, etc., and the insulator and contact are assembled and fixed by gluing. The structure is complex and the assembly efficiency is low. The above structure has problems such as more parts, inconvenient assembly and low production efficiency.

[0005] Therefore, in order to adapt to the increasingly competitive market situation, simplify the structure and improve production efficiency, it is necessary to design and develop a circular electrical connector with simple structure, reliable performance and high production efficiency to improve the competitiveness of the product.

DETAILED DESCRIPTION

[0025] The present application is further described in detail below in conjunction with the accompanying drawings and examples, but it should be noted that these implementation methods are not limitations of the present application, and equivalent changes or substitutions in functions, methods, or structures made by ordinary technicians in the field based on these implementation methods are all within the scope of protection of the present application.

[0026] In the description of the embodiments of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the creation of the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the creation of the present application.

[0027] In addition, the terms "first", "second", "third", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the invention of this application, unless otherwise specified, the meaning of "plurality" is two or more.

[0028] The terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the invention of this application can be understood by specific circumstances.

[0029] like Figure 1-6 As shown, a plastic electrical connector is provided, which includes a plug 1, a socket 2, and an O-ring 3 arranged between the plug 1 and the socket 2 for sealing between the plug 1 and the socket 2. The plug 1 includes a shell 11, a curved pipe 12 connected to the shell 11, a nut 13 for connecting the shell 11 and the curved pipe 12, and a wire collection sleeve 14 connected to the curved pipe 12. The nut 13 is fixed to the curved pipe 12 by a claw 15, and the claw 15 and the curved pipe 12 are an integral plastic compression molding structure.

[0030] In the plastic electrical connector provided in the above embodiment, except for the conductive parts, all parts are made of plastic material by plastic compression molding, which is dimensionally stable and has high structural strength. When the plug 1 is docked with the socket 2, the O-ring 3 is compressed to achieve the sealing of the docking end of the plug 1 and the socket 2. In the plastic electrical connector, the tail attachment adopts a claw 15 fixing structure, and the claw 15 and the elbow 12 are an integrated plastic compression molding structure, which utilizes the elasticity of the material of the plastic structure to achieve compression and rebound. The elbow 12 and the nut 13 utilize the compression and rebound of the claw 15, and can be assembled by pressing, which is simple to operate.

[0031] In some embodiments, there are multiple claws 15, and the multiple claws 15 are evenly distributed along the circumference of the elbow. The number of claws 15 can be selected according to the size of the space and actual needs. The uniform distribution along the circumference can make the force on the claws 15 more uniform, prevent the problem of some claws 15 being damaged due to excessive force, and increase the service life of the structure.

[0032] In some embodiments, the housing 11 is provided with the same number of housing stop convex keys 111 as the claws 15, and the stop convex keys 111 are inserted into the claw gaps 152. After the housing stop convex keys 111 are inserted into the claw gaps 151, the anti-rotation of the elbow 12 is achieved, and the angle of the elbow 12 is variable.

[0033] In some embodiments, the nut 13 is threadedly connected to the housing 11, and a sealing ring 16 is provided on the end surface of the elbow 12, and the sealing ring 16 is used to achieve sealing between the elbow 12 and the housing 11. After the plug 1 is installed, the sealing ring 16 is compressed to achieve sealing between the elbow 12 and the housing 11.

[0034] In some embodiments, the plug 1 is further provided with a connecting nut 17 that cooperates with the socket 2 , and the socket 2 is provided with a thread that cooperates with the connecting nut 17 .

[0035] In some embodiments, the plug 1 further includes a tail nut 18 for connecting the elbow 12 to the wire take-up sleeve 14 and a wire take-up pressing ring 19 disposed between the tail nut 18 and the wire take-up sleeve 14 for sealing.

[0036] In some embodiments, the outer circumferential wall of the housing 11 abuts against the inner circumferential wall of the claw 15. This prevents the claw 15 from shrinking inward and prevents the elbow 12 from being loosened due to force. Compared with the clamp spring fixation and circumferential rolling fixation in the existing structure, the claw connection structure has fewer parts, a simple assembly process, and a high structural strength, and can be adapted and applied in most electrical connector products.

[0037] In some embodiments, the socket 2 includes a square plate housing 21 and a square plate rubber pad 22 .

[0038] The above is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application. The above is only a preferred implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the present application, and these improvements and variations should also be regarded as the protection scope of the present application.
