Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mechanical electronics, more particularly to a terminal, a terminal assembly, a connector, and an automobile. BACKGROUND

[0002] A connector is a device for connecting two active devices to transmit current or signals. The connector can simplify the assembly process of electronic products, and also simplify the mass production process of electronic products. The connector is easy to maintain, and if a certain electronic component fails, the failed component can be quickly replaced in the case of the connector; with the advancement of technology, the electronic product with the connector can update the electronic component, replace the old electronic component with a new one with better performance, facilitating upgrading; the connector can improve the flexibility of product design when designing and integrating new products, and when using electronic components to form a system. Therefore, the connector is widely used in the fields of transportation, medical treatment, aerospace, military, household appliances, etc.

[0003] In some terminals of the connector, the interference fit between the outer surface of the body of the terminal and the inner surface of the sleeve ensures the coaxiality of the body of the terminal, the spring of the terminal, and the sleeve. However, the interference fit is very sensitive to the size and shape changes of the terminal and the sleeve. It is difficult to ensure the coaxiality of the sleeve and the body and the spring due to the machining errors of the body of the terminal and / or the sleeve usually provided on the body of the terminal, resulting in the offset between the sleeve and the body and the spring, and ultimately resulting in the failure of the mating terminal to be smoothly inserted into the spring and / or the body, thereby forming an unstable electrical connection between the terminal and the mating terminal, or even failing to form an electrical connection between the terminal and the mating terminal, causing the difficulty in assembling the terminal and the insufficient holding force between the terminal and the mating terminal.

[0004] Therefore, it is necessary to provide a terminal which is easy to assemble and has a large holding force. SUMMARY

[0005] Embodiments of the present application aim to solve at least one aspect of the above problems.

[0007] According to an aspect of the present application, the protrusions are configured to extend in a circumferential direction and / or an axial direction of the sleeve.

[0008] According to an aspect of the present application, a distance by which the plurality of protrusions protrude toward the cylindrical body is adjustable to adjust coaxiality between the sleeve and the cylindrical body and the elastic piece.

[0010] According to an aspect of the present application, the at least one set of protrusions includes a plurality of sets of protrusions distributed in an axial direction of the sleeve to enhance a holding force between the elastic piece and the counterpart terminal.

[0011] According to an aspect of the present application, the elastic piece includes two separate elastic pieces tapered in a direction away from the other end and facing each other.

[0012] According to an aspect of the present application, each of the separate elastic pieces is configured to have an arc-shaped cross section.

[0029] The present invention discloses a terminal 100, a terminal assembly 1000 including the terminal 100, a connector (not shown in the figure) including the terminal assembly 1000, and a vehicle (not shown in the figure) including the connector.

[0030] Terminal 100 is used to connect to the wire (not shown in the figure) and mating terminal 200 (see Figure 100). Figure 3 It includes: a cylindrical body 110, a crimping member 120, a spring 130, and a sleeve 140.

[0031] See Figures 1 to 6 The crimping member 120 is configured with four wings and is disposed at one end of the cylindrical body 110 for crimping the wire onto the terminal 100, thereby forming an electrical connection between the wire and the terminal 100. Spring tab 130 (see...) Figure 1 The mating terminal 200, which extends from the other end of the cylindrical body 110, is used for electrical connection between the inserts 130 and the mating terminals (see [link]). Figure 3 The spring 130 comprises two individual springs 130 that taper away from the other end and face each other. Each individual spring 130 is configured to have an arcuate cross-section. However, those skilled in the art should understand that the invention is not limited thereto, and the number of springs 130 may be three or more, and the cross-section of each spring 130 may also be configured in other suitable shapes to form a stable and reliable electrical connection with the mating terminal 200.

[0032] The sleeve 140 is fitted over the cylindrical body 110 and the spring 130 to prevent the spring 130 from excessively expanding and deforming outward when the connector 230 of the mating terminal 200 (described below) is inserted between the spring 130. This serves to limit the deformation or displacement of the spring 130, thereby forming a stable and reliable contact or electrical connection between the spring 130 and the connector 230 of the mating terminal 200 (see [link to product description]). Figure 6 The sleeve 140 includes at least one set of protrusions 141, each of which protrudes from the side wall of the sleeve 140 toward the cylindrical body 110 to abut against the cylindrical body 110 and along the circumferential direction D1 of the sleeve 140 (see [link]). Figures 2 to 4) each other to adjust the coaxiality between the sleeve 140 and the cylindrical body 110 and the spring pieces 130, thereby effectively avoiding the processing error of the cylindrical body 110 of the terminal 100 and / or the sleeve 140 arranged on the cylindrical body 110 of the terminal 100 from causing the sleeve 140 to deviate from the cylindrical body 110 and the spring pieces 130, so that the insertion piece 230 of the mating terminal 200 can be smoothly inserted between the spring pieces 130 or into the cylindrical body 110 to form a stable and reliable electrical connection with the terminal 100, facilitating the assembly of the terminal 100 and the mating terminal 200, and also being conducive to increasing the holding force between the terminal 100 and the mating terminal 200.

[0033] Although a set of protrusions 141 is shown in the vicinity of the middle part of the sleeve 140 in Figures 2 to 4 , a plurality of sets of protrusions 141 can also be arranged on other parts of the sleeve 140 to adjust the coaxiality between the sleeve 140 and the cylindrical body 110 and the spring pieces 130. The at least one set of protrusions 141 can include a plurality of sets of protrusions 141 distributed along the axial direction D2 of the sleeve 140 to enhance the holding force between the spring pieces 130 and the mating terminal 200, to further ensure that the spring pieces 130 form a stable and reliable electrical connection with the mating terminal 200.

[0034] The protrusions 141 can be configured to extend along the circumferential direction D1 and / or the axial direction D2 of the sleeve 140. The distance by which the plurality of protrusions 141 protrude towards the cylindrical body 110 is adjustable (see Figure 4 and 5 ) to adjust the coaxiality between the sleeve 140 and the cylindrical body 110 and the spring pieces 130. Although the protrusions 141 are configured as protrusions extending along the axial direction D2 in Figures 2 to 4 , the present application is not limited thereto, and the protrusions 141 can be configured in any suitable shape.

[0035] A terminal assembly 1000 according to an embodiment of the present application is shown in Figure 3 . The terminal assembly 1000 includes the terminal 100 and the mating terminal 200. The mating terminal 200 includes a cylindrical mating body 210, a mating crimping piece 220 configured in the form of four wing portions, and a cylindrical insertion piece 230. The mating crimping piece 220 is arranged at one end of the mating body 210 for crimping another wire (not shown in the figure) on the mating terminal 200. The insertion piece 230 extends from the other end of the mating body 210 to be inserted between the spring pieces 130, so that the terminal assembly 1000 electrically connects the wire with the other wire. Figure 6 The state in which the insertion piece 230 is inserted between the spring pieces 130 and the sleeve 140 is shown from Figure 6It can be seen that the protrusion 141 ensures good coaxiality between the spigot 230 and the spring 130 and the sleeve 140.
