AI Technical Summary
Existing right-angle connectors suffer from problems such as large size, complex assembly, and high cost, and the increased temperature at the contact point affects the current carrying capacity.
A plug and a small-volume bent connector were designed. By installing a head mounting plate and a socket assembly inside the head housing, and fixing them with a cover plate and a positioning block, a seal is achieved by combining a sealing groove and a sealing ring. The pin assembly and the centerline of the socket assembly are inserted at a 90° angle, which simplifies the assembly process and improves the contact reliability.
This has resulted in connectors that are small in size, simple in structure, and low in cost, while also improving current carrying capacity and contact reliability.

Abstract
Description
Technical Field
[0001] This utility model relates to bent connectors, and more particularly to a plug and a small-volume bent connector. Background Technology
[0002] With increasing customer demands for connectors and changes in product usage environments, the demand for bent connectors is growing. However, existing bent connectors have several drawbacks, such as large size, complex assembly processes, and high manufacturing costs. The demand for smaller, more reliable, and lower-cost connectors is becoming increasingly strong. Currently, bent connectors on the market are mostly of two types: 1. One type involves crimping the cable to the terminal block (bent), and then fixing the terminal block to the contact element with bolts or other methods. This connection method is complex and increases the number of contact points, leading to increased temperature at the junction of the terminal block and the contact element, affecting the product's current carrying capacity; 2. The other type uses bent contacts, but this structure has complex contact element manufacturing processes and high costs. Utility Model Content
[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a plug and a small-volume bent connector.

[0024] like Figure 4 and Figure 5 As shown, a small-volume bent connector includes a plug 20 and a socket 30, which are mated together. In this embodiment, as... Figure 1 As shown, the plug 20 includes a head housing 21, a head mounting plate 22 is installed inside the head housing 21, and a socket assembly 24 is installed inside the head mounting plate 22, such as... Figure 5As shown, the socket 30 includes a housing 31, a mounting plate 32 is installed inside the housing 31, and a pin assembly 33 is installed inside the mounting plate 32. The pin assembly 33 is inserted into the socket assembly 24, and the axis of the pin assembly 33 is not on the same straight line as the axis of the socket assembly 24. Preferably, the angle between the axis of the pin assembly 33 and the axis of the socket assembly 24 is 90°. Further, as... Figure 1 As shown, the head housing 21 has an upper-opening mounting cavity, which is covered by a cover plate 10 mounted on the head housing 21. A rib 28 is provided on the inner wall of the mounting cavity, and a positioning groove 27 corresponding to the rib 28 is provided on the outer wall of the head mounting plate. The rib 28 is engaged in the corresponding positioning groove 27. A mounting groove 26 is provided on the head mounting plate 22, and the insertion end of the socket assembly 24 is installed in the mounting groove 26. The insertion end of the socket assembly 24 has a limiting groove. A positioning block 23 is mounted on the head mounting plate 22, covering the upper opening of the mounting groove 26. Figure 3 As shown, the bottom of the positioning block 23 has two spaced positioning rods 25. The positioning rods 25 are engaged in the limiting slots of the socket assembly 24. In this embodiment, the head mounting plate 22 is an insulating mounting plate. The unique position of the head mounting plate 22 in the head housing 21 is ensured by the cooperation of the positioning groove 27 and the protruding rib 28. The two positioning rods 25 on the positioning block 23 cooperate with the limiting slots to ensure the fixed position of the socket assembly 24 in the head mounting plate 22. Moreover, the connecting end of the socket assembly 24 has a plug hole for insertion into the pin assembly 33. A spring contact finger 29, a crown spring, or a wire spring is installed in the plug hole to ensure the smoothness of insertion and removal and the reliability of contact when the pin assembly 33 and the socket assembly 24 are engaged.
[0025] In this embodiment, a process bracket is provided on the outer wall of the head housing 21, and a threaded hole is provided on the process bracket. The cover plate 10 is locked to the head housing 21 by a locking screw. The cover plate 10 can seal the connection end of the insertion hole assembly 24 and prevent foreign objects from entering the mounting cavity. When the cover plate 10 is installed, the lower end surface of the cover plate 10 presses against the positioning block 23 and the upper edge of the head mounting plate 22, thereby limiting the head mounting plate 22 and the positioning block 23. Furthermore, the connection end of the insertion hole assembly 24 has a contact plane, which fits against the bottom of the mounting groove 26. Preferably, as shown in the figure... Figure 2 As shown, the upper and lower surfaces of the connector end of the socket assembly 24 are both contact planes. When the positioning block 23 is installed, the upper contact plane fits with the positioning block 23, and the lower contact plane fits with the bottom of the mounting groove 26, thereby preventing the socket assembly 24 from rotating circumferentially.
[0026] In this embodiment, an annular sealing groove is provided on the upper end surface of the head housing 21, and a sealing ring is installed in the sealing groove. Therefore, when the cover plate 10 is installed, the contact area between the cover plate 10 and the head housing 21 can be sealed.
[0027] In this embodiment, during the assembly of the plug 20, the head mounting plate 22 is first installed into the head housing 21, then the pipe connector is inserted into the cable, the cable is crimped with the socket assembly 24, the crimped cable socket assembly 24 is passed through the threaded hole and installed into the corresponding position of the mounting plate, the socket position is adjusted so that its contact end plane is parallel to the inner surface of the mounting plate, then the positioning post of the positioning block 23 is inserted into the limiting slot, the positioning block 23 is flattened, the cover plate 10 is fastened to the head housing 21 with screws, and finally the pipe connector is tightened.
[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
