Description

Technical Field

[0001] This utility model relates to connectors, and more particularly to a toothed sleeve and connector. Background Technology

[0002] Conventional gear sleeve structures require front and rear bases (insulators) to clamp the gear sleeve in the middle. The components require two bases to be installed. The gear sleeve is fixed in the axial direction by the restriction of the two bases, but this makes the entire connector structure more complicated and inconvenient to assemble. Utility Model Content

[0004] The purpose of this utility model is achieved through the following technical solution: a toothed sleeve, including a ring-shaped body, a slot is provided on the body, the slot extends along the axial direction and penetrates the body, a window is provided at the front end of the body, an inwardly folded inner spring is provided on the rear side wall of the window, a notch is provided at the rear end of the body, and an outwardly folded outer spring is provided on the front side wall of the notch.

[0005] Optionally, there are three outer springs, which are evenly distributed on the same circumference.

[0006] Optionally, there are two windows, evenly distributed on the same circumference.

[0007] A connector includes a base, a contact, and a toothed sleeve. The toothed sleeve is fitted onto the contact. A stepped through hole is provided in the base. The contact is installed in the stepped through hole. An enlarged hole is provided at the junction of the large hole and the small hole of the stepped through hole. The toothed sleeve is located in the enlarged hole. A limiting protrusion is provided on the contact. The diameter of the limiting protrusion is between the diameter of the small hole and the diameter of the large hole of the stepped through hole. The circumferential diameter of the foremost end of the inner spring is smaller than the diameter of the contact. The circumferential diameter of the rear end of the outer spring is larger than the diameter of the large hole of the stepped through hole.

[0008] Optionally, the hole can be enlarged into a tapered hole with a smaller diameter at the front end and a larger diameter at the rear end.

[0009] Optionally, the length of the limiting protrusion ring is less than or equal to the axial length between the front end face of the window and the front end face of the body.

[0010] The present invention has the following advantages: The connector of the present invention has an inner spring and an outer spring in the toothed sleeve. The toothed sleeve can be directly installed in the enlarged hole to avoid toothed sleeve displacement. Moreover, after the contact is installed, the contact can be axially positioned, thus making the entire connector structure simple and easy to assemble. Attached Figure Description

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, a connector includes a base 30, a contact 20, and a toothed sleeve 10, as... Figure 6 As shown, the toothed sleeve 10 is fitted onto the contact member 20. A stepped through hole 31 is provided inside the base 30. The contact member 20 is installed within the stepped through hole 31. An enlarged hole 32 is provided at the junction of the large and small holes of the stepped through hole 31. The toothed sleeve 10 is located within the enlarged hole 32. A limiting protrusion 21 is provided on the contact member 20. The diameter of the limiting protrusion 21 is between the diameter of the small hole and the diameter of the large hole in the stepped through hole 31. In this embodiment, as shown... Figure 4 and Figure 5As shown, the toothed sleeve 10 includes a ring-shaped body 1 with a slot 2 extending axially and penetrating the body 1. A window 5 is provided at the front end of the body 1, and an inwardly folded inner spring piece 4 is provided on the rear side wall of the window 5. A notch is provided at the rear end of the body 1, and an outwardly folded outer spring piece 3 is provided on the front side wall of the notch. The circumferential diameter of the inner spring piece 4 is smaller than the diameter of the contact member 20, and the circumferential diameter of the outer spring piece 3 is larger than the diameter of the large hole in the stepped through hole 31. During installation, the toothed sleeve 10 is first inserted into the large hole of the stepped through hole 31. Because the toothed sleeve 10 has... The groove 2 is designed to reduce its size, thus altering the size of the toothed sleeve 10. After the toothed sleeve 10 is compressed circumferentially, it can be inserted into the larger hole of the stepped through-hole 31. During insertion, the outer spring 3 is compressed by the stepped through-hole 31, generating an elastic restoring force. When the toothed sleeve 10 is inserted into the enlarged hole 32, the outer spring 3 returns to its original position under the elastic restoring force, causing its rear end face to abut against the rear end face of the enlarged hole 32. Simultaneously, the toothed sleeve 10 returns to its original position, allowing its front end face to abut against the front end face of the enlarged hole 32, thereby preventing the toothed sleeve 10 from detaching from the enlarged hole. 32. Then, the contact 20 is inserted into the large hole of the stepped through hole 31. Since the diameter of the limiting protrusion 21 is between the diameter of the small hole and the diameter of the large hole of the stepped through hole 31, and the circumferential diameter of the foremost end of the inner spring piece 4 is smaller than the diameter of the contact 20, the inner spring piece 4 is expanded during the insertion of the contact 20, causing the inner spring piece 4 to generate an elastic restoring force. Furthermore, the length of the limiting protrusion 21 is less than or equal to the axial length between the front end face of the window 5 and the front end face of the body 1. That is to say, when the limiting protrusion 21 contacts the front end face of the enlarged hole 32, the inner spring piece 4 can pass over the limiting protrusion 21. 1. Furthermore, the inner spring plate 4 can clamp the contact 20 under the action of its elastic restoring force. When the contact 20 is subjected to an axially forward external force, it can avoid the contact 20 from moving axially forward by abutting the front end face of the limiting protrusion ring 21 against the front end face of the enlarged hole 32. When the contact 20 is subjected to an axially backward external force, the inner spring plate 4 can abut against the rear end face of the limiting protrusion ring 21, thereby avoiding the contact 20 from moving axially backward. This ensures the reliability of the contact 20 installation. Moreover, the toothed sleeve 10 is directly positioned by the base 30. Therefore, other bases are needed to prevent the toothed sleeve 10 from retracting.

[0025] In this embodiment, there are three outer spring pieces 3, evenly distributed on the same circumference, and two windows 5, also evenly distributed on the same circumference, thereby ensuring the reliability of the toothed sleeve 10 during use.

[0026] In this embodiment, the enlarged hole 32 is a tapered hole with a small front diameter and a large rear diameter. By setting the tapered hole, the toothed sleeve 10 can be installed better, making the whole structure more compact.

[0027] 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.
