Description

Technical Field

[0001] This utility model relates to the field of terminal fixing sleeve technology, and in particular to a terminal fixing sleeve. Background Technology

[0002] Connectors, as a common electrical connection device, are widely used in various fields of industrial production, especially in the consumer electronics field, where they are an important component of electronic products.

[0003] Connectors need to make electrical connections with mating components (such as mating connectors, circuit boards, or cables) to enable electrical transmission. The main function of connectors is to ensure the stable transmission of electrical signals, so that current can flow safely and reliably between various components.

[0004] Most existing electrical connector assemblies consist of a plug and a socket. Existing sockets generally include a socket body, a terminal retainer sleeve installed within the socket body, and conductive terminals installed within the terminal retainer sleeve. The existing terminal retainer sleeves are directly installed within the socket body, making them prone to loosening. This can lead to poor contact after connection, consequently affecting the normal use of the socket.

[0005] Therefore, in this utility model patent application, the applicant has carefully researched a terminal fixing sleeve to solve the above problems. Utility Model Content

[0006] The present invention addresses the shortcomings of the prior art by providing a terminal fixing sleeve that allows for the use of either sealant or sealing rings to ensure stability and reliability after installation, while also increasing the contact area with the insertion part to further ensure stability and reliability after insertion.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A terminal retaining sleeve for mounting in a socket and for installing conductive terminals includes a terminal retaining sleeve body having mounting cavities with left and right openings for mounting conductive terminals. A insertion portion is formed on the right end face of the terminal retaining sleeve body, and the mounting cavities extend to the right end face of the insertion portion.

[0009] The middle section of the terminal fixing sleeve body has several annular grooves on its outer periphery, spaced apart in the left and right direction, for installing sealant or sealing rings. The right end face of the terminal fixing sleeve body has a relief groove recessed to the left, and the insertion part protrudes to the right from the inner left side wall of the relief groove.

[0010] As a preferred embodiment, the outer periphery of the left section of the terminal fixing sleeve body is formed with external threads.

[0011] As a preferred embodiment, the outer periphery of the right end of the terminal fixing sleeve body is integrally formed with an annular limiting portion extending horizontally outward.

[0012] As a preferred embodiment, the mounting cavity includes a first inner cavity and a second inner cavity. The first inner cavity is connected to the second inner cavity through a third inner cavity. The first inner cavity passes through the left end face of the terminal fixing sleeve body, and the second inner cavity passes through the right end face of the terminal fixing sleeve body.

[0013] As a preferred embodiment, the inner diameter of the first inner cavity is larger than the inner diameter of the second inner cavity.

[0014] As a preferred embodiment, the third inner cavity is a frustum-shaped cavity that is larger on the left and smaller on the right.

[0015] As a preferred embodiment, the length of the first inner cavity is less than the length of the second inner cavity, and the length of the third inner cavity is less than the length of the first inner cavity.

[0016] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, it mainly uses an annular groove to allow for the selection of sealant or sealing ring according to usage requirements, thereby ensuring the stability and reliability after installation. Moreover, the design of the clearance groove can increase the contact area with the insertion part, further ensuring the stability and reliability after insertion.

[0017] Secondly, the external thread facilitates assembly.

[0018] To more clearly illustrate the structural features and effects of the present invention, a detailed description is provided below in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] like Figures 1 to 3 As shown, a terminal fixing sleeve is used to be installed in a socket and for installing conductive terminals, including a terminal fixing sleeve body 10.

[0031] The terminal fixing sleeve body 10 has mounting cavities 11 with left and right openings for mounting conductive terminals. A plug-in portion 12 is formed on the right end face of the terminal fixing sleeve body 10, and the mounting cavity 11 extends to the right end face of the plug-in portion 12.

[0032] In this embodiment, the mounting cavity 11 includes a first inner cavity 111 and a second inner cavity 112. The first inner cavity 111 passes through the left end face of the terminal fixing sleeve body 10, and the second inner cavity 112 passes through the right end face of the terminal fixing sleeve body 10. The inner diameter of the first inner cavity 111 is larger than the inner diameter of the second inner cavity 112, and the length of the first inner cavity 111 is smaller than the length of the second inner cavity 112.

[0033] The first inner cavity 111 is connected to the second inner cavity 112 through the third inner cavity 113, and the length of the third inner cavity 113 is less than the length of the first inner cavity 111. The third inner cavity 113 is a frustum-shaped cavity that is larger on the left and smaller on the right.

[0034] The outer periphery of the left section of the terminal fixing sleeve body 10 has an external thread 13. The outer periphery of the middle section of the terminal fixing sleeve body 10 is recessed with several annular grooves 14 spaced apart in the left-right direction for installing sealant or sealing rings. To better ensure the stability and reliability of the terminal fixing sleeve after it is installed in the socket, sealant or sealing rings can be used. For example, each annular groove 14 can be filled with sealant or a sealing ring, or different sealants or sealing rings can be installed in adjacent annular grooves 14.

[0035] The right end face of the terminal fixing sleeve body 10 is recessed to the left by a relief groove 15, and the plug-in part 12 is formed by protruding to the right from the inner left side wall of the relief groove 15. The relief groove 15 increases the contact area for subsequent connection with another plug-in socket, which is beneficial to improving the stability and reliability after connection with another plug-in socket.

[0036] The outer periphery of the right end of the terminal fixing sleeve body 10 is integrally formed with an annular limiting part 16 extending outward horizontally.

[0037] The key design feature of this utility model is that it mainly uses an annular groove, which allows for the selection of sealant or sealing ring according to usage requirements, thereby ensuring the stability and reliability after installation. Moreover, the design of the clearance groove can increase the contact area with the insertion part, further ensuring the stability and reliability after insertion.

[0038] Secondly, the external thread facilitates assembly.

[0039] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
