Description

Technical Field

[0001] The utility model relates to the field of mechatronics, and more particularly to a terminal, a terminal assembly, a connector, and an automobile. Background Art

[0002] A connector is a device used to connect 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 repair. If a certain electronic component fails, the failed component can be quickly replaced when the connector is installed; with the progress of technology, electronic products equipped with connectors can update electronic components, replacing old electronic components with new and better-performing electronic components, which is convenient for upgrading; the connector can improve the flexibility of product design when designing and integrating new products and when forming a system with electronic components. Therefore, connectors are widely used in fields such as transportation, medical treatment, aerospace, military, and household appliances.

[0003] In the terminals of some connectors, the interference fit between the outer surface of the terminal body and the inner surface of the sleeve ensures the coaxiality of the terminal body and the terminal spring piece and the sleeve. However, this interference fit is very sensitive to changes in the dimensions and shapes of the terminal and the sleeve. Due to the machining errors of the terminal body and / or the sleeve usually provided on the terminal body, it is difficult to ensure the coaxiality of the sleeve with the body and the spring piece, resulting in an offset between the sleeve and the body and the spring piece, and ultimately causing the mating terminal to be unable to be inserted smoothly, or even unable to be inserted into the spring piece and / or the body, thereby forming an unstable electrical connection between the terminal and the mating terminal, or even unable to form an electrical connection between the terminal and the mating terminal, resulting in difficult terminal assembly and insufficient holding force between the terminal and the mating terminal.

[0004] Therefore, there is a need to provide a terminal that is easy to assemble and has a large holding force. Summary of the Utility Model

[0026] The terms used herein are merely for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "including" used herein indicates the presence of features, steps, operations, but does not exclude the presence or addition of one or more other features.

[0027] In the case of using expressions such as "at least one of A, B, and C, etc.", generally, it should be interpreted according to the meaning that those skilled in the art usually understand this expression (for example, "a system having at least one of A, B, and C" should include, but is not limited to, a system having only A, only B, only C, having A and B, having A and C, having B and C, and / or having A, B, and C, etc.).

[0028] All terms used herein (including technical and scientific terms) have the meanings commonly understood by those of ordinary skill in the art, unless otherwise defined. It should be noted that the terms used herein should be interpreted as having a meaning consistent with the context of this specification, and should not be interpreted in an idealized or overly rigid manner.

[0029] The present utility model 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 an automobile (not shown in the figure) including the connector.

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

[0031] See Figures 1 to 6 , the crimping member 120 is configured in the form of 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. The spring piece 130 (see Figure 1 ) extends from the other end of the cylindrical body 110 for electrically connecting the mating terminal 200 (see Figure 3 ) inserted between the spring pieces 130. The spring piece 130 includes two separate spring pieces 130 that are tapered in a direction away from the other end and face each other. Each separate spring piece 130 is configured to have an arcuate cross-section. However, those skilled in the art should understand that the present utility model is not limited thereto, the number of the spring pieces 130 can be three or more, and the cross-section of each spring piece 130 can also be configured into other suitable shapes to form a stable and reliable electrical connection with the mating terminal 200.

[0032] The sleeve 140 is sleeved outside the cylindrical body 110 and the spring piece 130 to prevent the spring piece 130 from excessively expanding and deforming outward when the plug-in member 230 (to be described below) of the mating terminal 200 is inserted between the spring pieces 130, and thus plays a role in restricting the deformation or displacement of the spring piece 130 so as to form a stable and reliable abutment or electrical connection between the spring piece 130 and the plug-in member 230 of the mating terminal 200 (see Figure 6 ). The sleeve 140 includes at least one set of protrusions 141, and each protrusion 141 in the at least one set of protrusions 141 protrudes from the side wall of the sleeve 140 towards the cylindrical body 110 to abut against the cylindrical body 110 and along the circumferential direction D1 of the sleeve 140 (see Figures 2 to 4)Align with each other to adjust the coaxiality between the sleeve 140, the cylindrical body 110, and the elastic piece 130, thereby effectively avoiding the offset between the sleeve 140, the cylindrical body 110, and the elastic piece 130 caused by the machining errors of the cylindrical body 110 of the terminal 100 and / or the sleeve 140 provided on the cylindrical body 110 of the terminal 100, enabling the plug-in member 230 of the mating terminal 200 to be smoothly inserted between the elastic 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 beneficial to increasing the holding force between the terminal 100 and the mating terminal 200.

[0033] Although Figures 2 to 4 shows a set of protrusions 141 near the middle part of the sleeve 140, multiple sets of protrusions 141 can also be provided at other parts of the sleeve 140 to adjust the coaxiality between the sleeve 140, the cylindrical body 110, and the elastic piece 130. The at least one set of protrusions 141 can include multiple sets of protrusions 141 distributed along the axial direction D2 of the sleeve 140 to enhance the holding force between the elastic piece 130 and the mating terminal 200, so as to further ensure a stable and reliable electrical connection between the elastic piece 130 and the mating terminal 200.

[0034] The protrusion 141 can be configured to extend along the circumferential direction D1 and / or the axial direction D2 of the sleeve 140. The distance that the multiple protrusions 141 protrude towards the cylindrical body 110 is adjustable (see Figure 4 and 5 ) to adjust the coaxiality between the sleeve 140, the cylindrical body 110, and the elastic piece 130. Although in Figures 2 to 4 the protrusion 141 is configured as a rib extending along the axial direction D2, the present invention is not limited thereto, and the protrusion 141 can be configured into any suitable shape.

[0035] In Figure 3 shows a terminal assembly 1000 according to an embodiment of the present invention. 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 member 220 configured in the form of four wings, and a cylindrical plug-in member 230. The mating crimping member 220 is provided at one end of the mating body 210 for crimping another wire (not shown in the figure) onto the mating terminal 200. The plug-in member 230 extends from the other end of the mating body 210 to be inserted between the elastic pieces 130, so that the terminal assembly 1000 electrically connects the wire to the other wire. Figure 6 shows the state where the plug-in member 230 is inserted between the elastic pieces 130 and into the sleeve 140. From Figure 6It can be seen that due to the provision of the protrusion 141, good coaxiality between the connector 230, the elastic piece 130 and the sleeve 140 is ensured.
