[0002] When assembling common connector housings, the cylindrical rubber bushing is inserted and pressed into the hollow cylindrical plastic housing. The structural positioning is achieved only through the interference fit of the entire surface of the structure. This results in a large amount of material consumption, laborious and inconvenient disassembly and assembly, and the plastic housing is prone to cracking during pressing. Utility Model Content

[0003] The purpose of this utility model is to provide a lightweight, crack-resistant connector shell to solve the problem that common connector shells only achieve structural positioning through interference fit of the entire surface of the structure, resulting in large material consumption, laborious and inconvenient disassembly and assembly, and easy cracking of the plastic shell during press-fitting.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a lightweight, crack-resistant joint housing, comprising:

[0005] A rubber bushing with a bayonet at its outer end and a slot at its inner end;

[0006] A plastic outer shell has one end fitted onto the inner end of the rubber bushing and several circumferentially spaced clamping plates. The clamping plates abut against the surface of the rubber bushing, and the clamping blocks on their inner sides engage with the latches. Several sealing rings are provided between the inner end of the rubber bushing and the inner wall of the plastic outer shell. The plastic outer shell has a socket corresponding to the plug, and a pin passes through the socket and is embedded in the plug.

[0007] As a further description of the above technical solution:

[0008] The outer end of the rubber bushing is provided with a flange, which is fitted onto the end face of the card plate.

[0009] As a further description of the above technical solution:

[0010] Several of the sealing rings are respectively embedded in several annular grooves arranged axially at intervals on the outer surface of the rubber bushing.

[0011] As a further description of the above technical solution:

[0012] The plastic shell is provided with annular reinforcing ribs extending radially outward, and the sealing ring is embedded in the groove inside the annular reinforcing ribs.

[0013] As a further description of the above technical solution:

[0014] A first countersunk groove extends from the outer side of the socket.

[0015] As a further description of the above technical solution:

[0016] A second countersunk groove extends outward from the outer side of the insertion hole.

[0017] In summary, by adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:

[0018] This utility model's connector housing reduces material waste and achieves a lightweight design by replacing the hollow cylinder at the end with several clamping plates. The rubber bushing and plastic housing are fitted together with an interference fit, and then engaged with clamping blocks and slots to improve assembly strength. The clamping blocks also release stress when the rubber bushing and plastic housing are joined. The pins further reinforce the structural positioning of both components, avoiding the problem of excessive compression and cracking caused by conventional rubber bushing and plastic housing joints that rely solely on interference fits for structural positioning. This design also facilitates insertion and press-fitting. The sealing ring applies an elastic pre-tightening force to the plastic housing through annular reinforcing ribs, improving its structural strength and extending its service life.

[0026] Please see Figure 1-2 This utility model provides a technical solution: a lightweight crack-resistant joint housing, comprising:

[0027] A rubber bushing 1 has a bayonet 2 at its outer end and an insertion port 3 at its inner end;

[0028] The plastic shell 4 has one end fitted inside the rubber bushing 1 and has several circumferentially spaced clamping plates 5. The clamping plates 5 abut against the surface of the rubber bushing 1, and the clamping blocks 6 on the inner side of the clamping plates 5 are engaged with the clamping slots 2. Several sealing rings 7 are provided between the inner end of the rubber bushing 1 and the inner wall of the plastic shell 4. The plastic shell 4 has a socket 8 corresponding to the socket 3. The pin 9 passes through the socket 8 and is embedded in the socket 3.

[0029] The outer end of the rubber bushing 1 is provided with a flange 10, which fits onto the end face of the clamping plate 5. This improves the assembly strength.

[0030] Several sealing rings 7 are respectively embedded in several annular grooves 11 arranged axially at intervals on the outer surface of the rubber bushing 1. Annular reinforcing ribs 12 extend radially outward on the plastic shell 4, and the sealing rings 7 are embedded in grooves inside the annular reinforcing ribs 12. This enhances the structural strength of the plastic shell 4, facilitates the positioning of the sealing rings 7, and improves assembly tightness.

[0031] The outer side of the socket 3 extends a first countersunk groove 13. The outer side of the insertion hole 8 extends a second countersunk groove 14 to increase the structural thickness of the outer side of the hole structure and prevent the pin 9 from wearing down, which would reduce the structural stability.

[0032] The assembly process of a lightweight anti-cracking connector shell in this embodiment includes: putting the sealing ring 7 on the rubber bushing 1 and embedding it into the annular groove, inserting the rubber bushing 1 into the plastic shell 4 from the outer end of the clamping plate 5 until the clamping plate 5 abuts against the flange 10, and the clamping block 6 is inserted into the clamping slot 2. At this time, the sealing ring 7 is embedded in the inner side of the annular reinforcing rib 12. Finally, the pin 9 is passed through the insertion hole 8 and embedded into the insertion slot 3 to complete the assembly.

[0033] In summary, due to the adoption of the above technical solution, the lightweight crack-resistant joint housing of this embodiment has the following advantages compared with the prior art:

[0034] This utility model's connector housing reduces material waste and achieves a lightweight design by replacing the hollow cylinder at the end with several clamping plates. The rubber bushing and plastic housing are fitted together with an interference fit, and then engaged with clamping blocks and slots to improve assembly strength. The clamping blocks also release stress when the rubber bushing and plastic housing are joined. The pins further reinforce the structural positioning of both components, avoiding the problem of excessive compression and cracking caused by conventional rubber bushing and plastic housing joints that rely solely on interference fits for structural positioning. This design also facilitates insertion and press-fitting. The sealing ring applies an elastic pre-tightening force to the plastic housing through annular reinforcing ribs, improving its structural strength and extending its service life.
