Description

Technical Field

[0001] This application relates to the field of terminal technology, and in particular to a connecting terminal. Background Technology

[0002] Currently, terminals are accessory products used to achieve electrical connections, and are classified as connectors in industry. With increasing industrial automation and more stringent and precise industrial control requirements, the usage of terminals is gradually rising. With the development of the electronics industry, the application range of terminals is expanding, and the types are also increasing.

[0003] One related technology includes a terminal block that mainly comprises an insulating sheath and a conductive component that is inserted and fixed inside the insulating sheath at one end, with the other end of the conductive component protruding from the insulating sheath. All insulating sheaths are integrally formed on one side of a strip. The insulating sheaths are sequentially connected using the strip, thus meeting the needs of mass production of terminals.

[0004] For the aforementioned insulated terminals, during the wiring process, the wire needs to be inserted into the conductive component through the inlet of the insulating sheath first, and then the conductive component is squeezed with wire crimping pliers to press the conductive core of the wire tightly into the conductive component. However, since the inner wall of the conductive component is usually relatively smooth, the conductive core is prone to slipping out of the conductive component and into the insulating sheath when subjected to external force before it is pressed tightly by the wire crimping pliers. If the conductive component is squeezed at this time, it will directly cause the terminal to be scrapped. Utility Model Content

[0005] This application provides a terminal block that can fix wires in place, making them less likely to detach from the conductive component.

[0006] The technical solution for a connecting terminal provided in this application is as follows:

[0007] A terminal block includes an insulating sheath and a conductive element with one end fixed to the insulating sheath. Multiple sets of limiting members located within the insulating sheath are disposed on the inner wall of the conductive element. One end of each limiting member is fixed to the inner wall of the conductive element, and the other end of each limiting member is inclined away from the inlet of the insulating sheath. The limiting member is used to abut against the outer wall of a conductive core inserted into the conductive element. The limiting members in the same set are arranged in a circumferentially evenly spaced ring around the central axis of the conductive element.

[0008] By adopting the above technical solution, the conductive wire core is inserted into the conductive component. At this time, the limiting component will abut against the outer wall of the conductive wire core. The limiting component will limit and fix the conductive wire core in the conductive component, thereby improving the tensile strength of the wire, making it difficult for the conductive wire core to detach from the conductive component, facilitating the fixing of the wire, increasing the success rate of the subsequent crimping pliers to press the conductive wire core into the conductive component, and reducing the scrap rate.

[0009] Preferably, the limiting members in each group are arranged at intervals along the length of the central axis of the conductive member.

[0010] Preferably, a plurality of reinforcing rings are integrally formed on the outer side wall of the conductive component and located inside the insulating sheath. The reinforcing rings correspond one-to-one with each set of limiting components, and the reinforcing rings are located outside their respective limiting components.

[0011] Preferably, the inner wall of the conductive element is provided with a serrated segment located outside the insulating sheath, and the length of the serrated segment extends along the length direction of the central axis of the conductive element.

[0012] Preferably, the inner wall of the insulating sheath is integrally formed with a circumferentially arranged guide slope, which is used to guide the conductive core toward the conductive element.

[0013] Preferably, a plurality of abutment blocks are integrally formed on the inner sidewall of the insulating sheath, the abutment blocks are arranged circumferentially around the central axis of the insulating sheath, and deformation grooves are formed between adjacent abutment blocks.

[0014] Preferably, a strip is integrally formed between the outer walls of adjacent insulating sheaths, and the strip connects the insulating sheaths sequentially.

[0015] In summary, this application includes at least one of the following beneficial technical effects:

[0016] It improves the tensile strength of the wire, making it less likely for the conductive core to detach from the conductive component, which facilitates the fixing of the wire and increases the success rate of the subsequent wire crimping pliers in pressing the conductive core into the conductive component, thus reducing the scrap rate.

[0017] When the wire crimping pliers press the conductive wire core into the conductive component, the serrated segments on the inner wall of the conductive component will engage with the conductive wire core, thereby further improving the wire's tensile strength and enhancing the reliability and strength of the connection between the conductive wire core and the conductive component.

[0021] The present application will be further described in detail below with reference to the accompanying drawings.

[0022] This application discloses a connecting terminal.

[0023] Reference Figure 1 , Figure 2 The terminal includes an insulating sleeve 1 and a conductive element 2 fixedly mounted on the insulating sleeve 1 at one end. Multiple sets of limiting elements 3 located inside the insulating sleeve 1 are integrally formed on the inner wall of the conductive element 2. Each limiting element 3 in the same set is arranged in a circumferentially and evenly spaced around the central axis of the conductive element 2 on the inner wall of the conductive element 2.

[0024] like Figure 1 , Figure 2 As shown, adjacent sets of limiting members 3 are arranged at intervals along the length of the central axis of the conductive element 2. One end of the limiting member 3 is fixed to the inner wall of the conductive element 2, and the other end of the limiting member 3 is inclined away from the inlet of the insulating sheath 1. The limiting member 3 is used to abut against the outer wall of the conductive core inserted into the conductive element 2. When the conductive core is inserted into the conductive element 2 from the inlet of the insulating sheath 1, under the guidance of the surrounding limiting members 3, the conductive core will eventually be inserted into the conductive element 2 along the central axis of the conductive element 2. During this process, the conductive core will push the surrounding limiting members 3 to open away from the central axis of the conductive element 2. At this time, the limiting members 3 will apply a compressive force to the conductive core, thereby limiting and fixing the conductive core inside the conductive element 2.

[0025] like Figure 1 , Figure 2 As shown, multiple reinforcing rings 20 are integrally formed on the outer wall of the conductive component 2, located within the insulating sleeve 1, and are fixedly connected to the insulating sleeve 1. The reinforcing rings 20 further enhance the structural strength of the connection between the conductive component 2 and the insulating sleeve 1, making the connection less prone to breakage. The reinforcing rings 20 are coaxially arranged with the conductive component 2, and each reinforcing ring 20 corresponds one-to-one with a set of limiting members 3, with each reinforcing ring 20 located outside its respective limiting member 3. The reinforcing rings 20 are arranged sequentially at intervals along the length of the central axis of the conductive component 2. When the limiting members 3 are gradually opened under the push of the conductive core, the reinforcing rings 20 enhance the structural strength of the conductive component 2, thereby reducing the deformation of the conductive component 2.

[0026] like Figure 1 , Figure 2 As shown, a serrated segment 21 is integrally formed on the inner wall of the conductive component 2, located outside the insulating sheath 1. The length of the serrated segment 21 extends along the length direction of the central axis of the conductive component 2. When the wire clamps press the conductive core into the conductive component 2, the serrated segment 21 on the inner wall of the conductive component 2 will engage with the conductive core, thereby further improving the tensile strength of the wire and further enhancing the reliability and strength of the connection between the conductive core and the conductive component 2.

[0027] like Figure 1 , Figure 2 As shown, the inner wall of the insulating sheath 1 is integrally formed with a circumferentially arranged guide slope 10. The guide slope 10 is used to guide the conductive core towards the conductive element 2, thereby ensuring that the conductive core is smoothly inserted into the conductive element 2.

[0028] like Figure 1 , Figure 2 As shown, multiple contact blocks 4 are integrally formed on the inner wall of the insulating sleeve 1, near the wire inlet of the insulating sleeve 1. The contact blocks 4 are arranged circumferentially and evenly spaced around the central axis of the insulating sleeve 1, and a deformation groove 40 is formed between two adjacent contact blocks 4. When the wire is inserted into the insulating sleeve 1, the contact blocks 4 will abut against the outer wall of the wire, thereby further improving the limiting and fixing effect of the wire, making the wire more stable and securely fixed within the insulating sleeve 1. Since the wire will deform to a certain extent when squeezed by the external contact blocks 4, the deformation groove 40 can provide a certain deformation space for the wire, while further improving the limiting effect of the wire and restricting the wire from rotating within the insulating sleeve 1.

[0029] like Figure 1 , Figure 2 As shown, a strip 5 is integrally formed between the outer walls of adjacent insulating sleeves 1, and the strip 5 connects and fixes each insulating sleeve 1 in sequence.

[0030] The implementation principle is as follows: the conductive core is gradually inserted into the conductive component 2 from the inlet of the insulating sheath 1. At this time, the limiting component 3 will abut against the outer wall of the conductive core. The limiting component 3 will limit and fix the conductive core in the conductive component 2, thereby improving the tensile strength of the wire and making it difficult for the conductive core to come out of the conductive component 2. This makes it easier to fix the wire, increases the success rate of the subsequent crimping pliers to press the conductive core into the conductive component 2, and reduces the scrap rate.

[0031] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
