[0001] The utility model relates to the technical field of electrical connectors, in particular to a highly sealed plastic connector socket. Background Art

[0002] In addition to meeting general performance requirements, an especially important requirement for electrical connectors is that they must achieve good contact, reliable operation, and convenient maintenance. Whether they operate reliably directly affects the normal operation of aircraft circuits and involves the safety of the entire host.

[0003] Such as Figure 5 and Figure 6 As shown, it is the structure of the previous generation of plastic connector sockets. The following deficiencies exist in the actual use of this plastic connector socket structure: Since the external electrical connector is installed on the plastic connector socket in a spiral manner, it causes external dust or moisture to easily enter the socket through the connection gap between the nut and the external screw tube, resulting in problems such as contamination of the electrical connection terminals, poor contact, and moisture-induced aging, reducing the safety and stability of the actual use of the plastic connector socket.

[0004] In view of this, it is particularly important to design and manufacture a sealing structure for plastic connector sockets that can comprehensively seal the electrical connection part of the electrical connector and improve the safety and stability of electrical connection during the design, manufacture, and use of plastic connector sockets. Content of the Utility Model

[0005] The purpose of the utility model is to: In order to solve the problem that in traditional plastic connector sockets, external dust and moisture easily enter the socket, and the sealing effect after the connection of the electrical connector is poor, reducing the safety and stability after the connection of the electrical connector, a highly sealed plastic connector socket is proposed.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A highly sealed plastic connector socket includes a base, an external screw tube fixed in the middle of the front end of the base, mounting holes opened at four corners of the base, a power cord installed at the rear end of the base, and a plurality of electrical connection terminals installed at the front end of the power cord and located inside the external screw tube. A sealing part for comprehensive sealing treatment is provided between the base and the external screw tube after the external electrical connector is installed on the plastic connector socket.

[0008] As a further description of the above technical scheme:

[0009] The sealing part includes an anti-offset retaining ring integrally fixed inside the external screw tube, an inner embedding groove opened between the front end of the external screw tube and the anti-offset retaining ring, and a first sealing ring embedded inside the inner embedding groove.

[0010] As a further description of the above technical solution:

[0011] The sealing portion further includes a second sealing ring sleeved outside the outer screw tube and fitting with the front end surface of the base, and a limiting ring integrally fixed to the front end of the base and covering the second sealing ring.

[0012] As a further description of the above technical solution:

[0013] A hollow cavity is provided in the middle of both the first sealing ring and the second sealing ring, and sealing glue is filled in the hollow cavities of the first sealing ring and the second sealing ring.

[0014] As a further description of the above technical solution:

[0015] A first outer convex ring protruding outward is integrally fixed and connected to the middle of the front end of the first sealing ring.

[0016] As a further description of the above technical solution:

[0017] A second outer convex ring protruding outward is integrally fixed and connected to the middle of the front end of the second sealing ring, and a side buckle strip that can fit with the outer periphery of the external electrical connector is integrally fixed and connected to the outer edge part of the front end of the second sealing ring.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the present utility model are as follows:

[0019] In the present utility model, by scientifically and reasonably improving the original socket structure, an anti-offset retaining ring, an embedded groove, a first sealing ring, a second sealing ring and a limiting ring are provided between the outer screw tube and the base. When the inner screw sleeve of the external electrical connector is screwed onto the outer screw tube on the base, the first sealing ring can actively seal the connection part between the inner screw sleeve and the outer screw tube, and at the same time, the second sealing ring can actively seal the connection part between the inner screw sleeve, the base and the outer screw tube. At this time, a sealed cavity will be formed between the inner screw sleeve and the outer screw tube. This structure can perform multi-faceted comprehensive sealing on the connection gap between the external electrical connector and the plastic connector socket, effectively reducing the occurrence of problems such as pollution of the electrical connection terminals, poor contact and damp aging caused by the entry of external dust and water vapor, thereby improving the safety and stability of the actual use of the plastic connector socket.

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figures 1-6 , the present invention provides a technical solution: a highly sealed plastic connector socket, including a base 1, an outer screw tube 101 fixed in the middle of the front end of the base 1, mounting holes 105 opened at the four corners of the base 1, a power cord 2 installed at the rear end of the base 1, and a plurality of power connection terminals 201 installed at the front end of the power cord 2 and located inside the outer screw tube 101. A sealing portion for comprehensive sealing treatment is provided between the base 1 and the outer screw tube 101 after an external electrical connector is installed on the plastic connector socket.

[0030] Specifically, as Figures 1-4As shown in the figure, the sealing part includes an anti-deviation retaining ring 102 integrally fixed inside the outer screw tube 101, an embedded groove 103 opened between the front end of the outer screw tube 101 and the anti-deviation retaining ring 102, and a first sealing ring 3 embedded inside the embedded groove 103. At the same time, the sealing part also includes a second sealing ring 4 sleeved outside the outer screw tube 101 and fitting with the front end face of the base 1, and a limiting ring 104 integrally fixed at the front end of the base 1 and covering the second sealing ring 4. The first sealing ring 3 can internally seal the connection part between the inner screw sleeve and the outer screw tube 101, while the second sealing ring 4 can externally seal the connection part between the inner screw sleeve, the base 1 and the outer screw tube 101. At this time, a sealed cavity will be formed between the inner screw sleeve and the outer screw tube 101.

[0031] A hollow cavity 5 is provided in the middle of both the first sealing ring 3 and the second sealing ring 4. Compared with the solid-structured first sealing ring 3 and second sealing ring 4, the first sealing ring 3 and the second sealing ring 4 with the hollow cavity 5 are softer in texture and can fill and seal the connection gap between the external electrical connector and the connector socket. The hollow cavities 5 of the first sealing ring 3 and the second sealing ring 4 are filled with sealant 6, which can improve the sealing effect of the first sealing ring 3 and the second sealing ring 4. When the first sealing ring 3 and the second sealing ring 4 are locally pressed, the sealant 6 can move to other non-pressed parts in the hollow cavity 5, enabling the first sealing ring 3 and the second sealing ring 4 to better fit with the external electrical connector and the connector socket.

[0032] Specifically, as Figures 1-4 shown, a first outer convex ring 301 protruding outward is integrally fixed to the middle of the front end of the first sealing ring 3, which can increase the contact area between the first sealing ring 3 and the inner screw sleeve of the external electrical connector, thereby improving the internal sealing effect of the first sealing ring 3. At the same time, a second outer convex ring 401 protruding outward is integrally fixed to the middle of the front end of the second sealing ring 4, which can increase the contact area between the second sealing ring 4 and the outer end of the inner screw sleeve of the external electrical connector, thereby improving the external sealing effect of the second sealing ring 4. A side buckle strip 402 that can fit with the outer circumference of the external electrical connector is integrally fixed to the outer edge part of the front end of the second sealing ring 4. On the one hand, it can stably limit the second sealing ring 4 between the base 1 and the outer screw tube 101. On the other hand, it can prevent the second sealing ring 4 from expanding and deforming outward after being squeezed, thereby further improving the external sealing effect of the second sealing ring 4.

[0033] Working principle: When in use, the plastic connector socket can be installed and fixed to the power distribution cabinet or other electrical equipment through the base 1 and fasteners. When the connection operation of the external electrical connector needs to be carried out, the operator can orient and screw the inner nut on the external electrical connector onto the external screw tube 101 on the base 1. After the inner nut is completely screwed into the space between the external screw tube 101 and the base 1, the first sealing ring 3 and the second sealing ring 4 will be in a compressed state. The first sealing ring 3 can perform internal sealing on the connection part between the inner nut and the external screw tube 101. At the same time, the second sealing ring 4 can perform external sealing on the connection part between the inner nut, the base 1 and the external screw tube 101. Under the combined sealing and blocking effect of the first sealing ring 3 and the second sealing ring 4, a sealed cavity will be formed between the inner nut and the external screw tube 101, thereby being able to prevent external dust and water vapor from entering the socket interior through the connection gap, improving the sealing effect after the external electrical connector is installed on the socket.

[0034] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent replacements or changes, shall be covered by the protection scope of the present utility model.
