[0002] Terminals are the most commonly used components in automotive connectors, used to transmit power or signals and provide support for electrical connections. With the enrichment of functions for automotive electrical devices, miniaturization, modularization, and reliability of connectors are becoming three development trends for connectors.

[0003] Currently, junction box terminals made from copper alloy strips are commonly used. These junction box terminals are easy to meet a single insertion and withdrawal force. However, to meet multiple insertion and withdrawal actions, high demands are placed on the junction box terminal performance. In the current technology, different junction box terminal compression forces are required for the male pins of plug terminals coated with different materials when the male pins of plug terminals of the same size are inserted into the junction box terminals. Therefore, a junction box terminal is only adapted to a plug terminal coated with the same material, and the junction box terminal and the male pin terminal cannot be used together.

[0021] As with regard to Fig. As shown in Figures 1 to 5, the present embodiment provides a box terminal with a resilient sheet. It comprises a body 100, wherein the body 100 is provided with a resilient plate 300, wherein a first end of the resilient plate 300 is firmly connected to the body 100 and a second end of the resilient plate 300 represents a free end, wherein the second end of the resilient plate 300 is bent towards the first end of the resilient plate 300, thereby forming a plug-in groove 310, wherein a side wall at the second end of the resilient plate 300 is bent towards an inner side of the plug-in groove 310, thereby providing a bent elevation 320, wherein upon insertion of a plug-in pin 410 of a plug terminal 400 into the plug-in groove 310, the bent elevation 320 and a side wall at the first end of the resilient plate 300 can fix the plug-in pin 410 by pressing,and wherein the size of a distance H1 between the curved protrusion 320 and the side wall at the first end of the resilient sheet 300 is adjustable to adapt to the plug pin 410 coated with different materials.

[0022] In the prior art, a coating would also typically be added to a surface of the connector terminal 400 to enhance the aesthetics of the connector terminal 400, improve corrosion protection, increase electrical conductivity, or enhance solderability. Due to the difference in the coating with regard to electrical conductivity, friction coefficient, softness or hardness, and the like, it is necessary to provide different compressive forces for the plug pins 410 of the connector terminals 400 with different coatings in order to prevent the plug pin 410 from slipping between a contact plate and the first resilient sheet 300 and to avoid damaging the coating.

[0023] In the present embodiment, it is provided that the size of the distance H1 between the curved protrusion 320 and the side wall at the first end of the resilient plate 300 is adjusted in order to change a degree of deformation of the resilient plate 300 when inserting the plug pin 410 into the plug groove 310, and to realize a change in a compressive force from the curved protrusion 320 and the side wall at the first end of the resilient plate 300 on the plug pin 410, so that the box terminal with a resilient plate can be adapted to plug pins 410 that are coated with different materials, has a simple structure and strong adaptability. In addition, when inserting or withdrawing the plug pin 410 into or from thefrom the plug-in groove 310, only the curved elevation 320 and the side wall at the first end of the resilient plate 300 press the plug-in pin 410 by elastic restoring force of the resilient plate 300, whereby the plug-in or plug-out of the plug-in pin 410 is smooth and a stable connection is achieved.

[0024] In particular, an angle between the side wall at the first end of the resilient plate 300 and the side wall at the second end of the resilient plate 300 is adjusted to change the distance H1 between the curved protrusion 320 and the side wall at the first end of the resilient plate 300, which is simple and convenient.

[0025] In the present embodiment, it is provided that a value of the distance H1 between the curved elevation 320 and the side wall at the first end of the resilient sheet 300 depends on the coating material of the resilient sheet 300, the coating material of the plug terminal 400, and the size of the plug pin 410; and that the smaller the distance H1 between the curved elevation 320 and the side wall at the first end of the resilient sheet 300, the greater the compressive force from the curved elevation 320 and the side wall at the first end of the resilient sheet 300 on the plug pin 410 when the plug pin 410 is inserted into the plug groove 310.

[0026] The distance H1 between the curved protrusion 320 and the side wall at the first end of the resilient sheet 300 is in particular 0.05 mm - 0.45 mm. The distance H1 between the curved protrusion 320 and the side wall at the first end of the resilient sheet 300 is preferably 0.15 mm, 0.2 mm, 0.25 mm, or 0.3 mm.

[0027] In particular, coatings are applied to the surface of the box terminal with a resilient sheet. The coating material can be gold, silver, nickel, tin, or another material, but is not limited thereto. Of course, the coating material of the box terminal with a resilient sheet can be the same as the coating material of the plug terminal 400, or it can be different from the coating material of the plug terminal 400.

[0028] In the present embodiment, it is provided that a distance H2 between a contact point of the curved protrusion 320 and an end face of the body 100 is adjustable. Typically, the depth to which the plug pin 410 is inserted into the plug groove 310 is a constant value. When ensuring that the distance H2 between the contact point of the curved protrusion 320 and the end face of the body 100 is appropriate, the greater the distance H2 between the contact point of the curved protrusion 320 and the end face of the body 100, the smaller the distance between the contact point of the curved protrusion 320 and the deepest point of the plug groove 310, and the greater the force exerted by the curved protrusion 320 and the side wall at the first end of the resilient plate 300 on the plug pin 410.This allows the spring-loaded terminal to be adapted to 410 pins coated with a wider variety of materials, thus increasing the adaptability of the spring-loaded terminal.

[0029] The distance H2 between the contact point of the curved protrusion 320 and the end face of the body 100 is in particular 1.5 mm - 3 mm. The distance H2 between the contact point of the curved protrusion 320 and the end face of the body 100 is preferably 1.8 mm, 2.4 mm, or 2.8 mm.

[0030] What next regarding Fig. 1, in the present exemplary embodiment, the curved elevation 320 is provided at the second end of the resilient plate 300, and the end face at the second end of the resilient plate 300 is arranged at an angle facing away from the side wall at the first end of the resilient plate 300, so that the end face of the plug-in groove 310 is widened. In the present exemplary embodiment, it is provided that when the plug-in pin 410 is inserted into the plug-in groove 310, the widened end face of the plug-in groove 310 has a guiding effect, which is expedient for inserting the plug-in pin 410 into the plug-in groove 310.

[0031] What next regarding Fig. 1, in the present embodiment, a crimp tail 200 is connected to the body 100, the crimp tail 200 being used to connect a wire. In particular, the crimp tail 200 and the body 100 are formed as a single piece, which leads to convenient mass production. Furthermore, it is provided that the crimp tail 200 and the body 100 can be formed as a single piece by stamping, but is not limited thereto. Furthermore, it is provided that the material of the box terminal with a resilient sheet can be copper alloy, but is not limited thereto. The copper alloy has high performance and is advantageous for the box terminal with a resilient sheet to be formed as a single piece by stamping.

[0032] In particular, a wire crimping plate 210 is arranged in a bent manner on the crimp tail 200. The wire crimping plate 210 can be bent and crimps and fixes a wire through it, making wiring simple and reliable. In particular, a groove 211 is provided on an inner side of the crimp tail 200. When the wire crimping plate 210 presses the wire against the crimp tail 200, the wire can be pressed to bend and thus embedded in the groove 211, so that the wire is crimped more securely.

[0033] In particular, the body 100 is an integrally formed box structure, and the resilient plate 300 is formed within the box structure. The integrally formed box structure is convenient for manufacturing and coupling the plug terminal 400 to the receptacle terminal with a resilient plate. In particular, the first end of the resilient plate 300 is firmly connected to an inner side wall of the box structure. In the present embodiment, the resilient plate 300 is formed within the box structure. This is convenient for storage, can effectively prevent the resilient plate 300 from deforming due to impact, pulling, hanging, or pushing, and avoids the impact on the performance of using the receptacle terminal with a resilient plate.

[0034] What next regarding Fig. 1, in the present embodiment, the body 100 is provided with an escape groove 110, wherein the end face at the second end of the resilient plate 300 is provided corresponding to the escape groove 110. When the plug pin 410 of the plug terminal 400 is inserted into the plug groove 310, the escape groove 110 escapes the end face at the second end of the resilient plate 300 to prevent interference, so that the box terminal with a resilient plate becomes structurally more compact.

[0035] What next regarding Fig. 1, in the present exemplary embodiment, the body 100 is provided with a resilient locking plate 120, wherein the resilient locking plate 120 can be locked to an outer housing, wherein the outer housing is not shown in the figures. In particular, the outer housing is provided with a receiving groove for receiving the box terminal with a resilient plate. A locking section for locking with the resilient locking plate 120 is provided in the receiving groove. In the present exemplary embodiment, the locking section is not defined with regard to its structure and shape. Furthermore, it is provided that the resilient locking plate 120 is arranged on a side of the body 100 connected to the resilient plate 300. In particular, the resilient locking plate 120 is formed by bending the side wall of the box structure, which is expedient for the manufacture or production of the body 100.

[0036] What next regarding Fig. 1 and Fig. As shown in FIG. 2, in the present embodiment, the body 100 is provided with a restricting portion. The restricting portion can restrict a bending angle of the side wall at the second end of the resilient plate 300, effectively preventing the fatigue elasticity of the resilient plate 300 from being damaged by excessive bending of the resilient plate 300. This extends the service life of the can terminal with a resilient plate. Specifically, the restricting portion is arranged below the side wall at the second end of the resilient plate 300, and the restricting portion is formed by bending the side wall of the box structure, which is convenient for the stamped forming of the body 100.

[0037] Furthermore, it is provided that the limiting portion is formed by bending the inner side wall of the escape groove 110, which is expedient for the stamped formation of the body 100.

[0038] In particular, the limiting portion can be configured as a limiting plate 111, which is provided by bending the body 100 toward the resilient plate 300. In the present embodiment, the side wall at the second end of the resilient plate 300 can be bent such that it can abut the end face of the limiting plate 111, thus limiting the bending angle of the side wall at the second end of the resilient plate 300.

[0039] Of course, the limiting portion can also be configured as a resilient stop plate 112 provided by bending the body 100 toward the resilient plate 300. In the present embodiment, the side wall at the second end of the resilient plate 300 can be bent so that it can abut against the inner side wall of the resilient stop plate 112, so that the bending angle of the side wall at the second end of the resilient plate 300 is limited, and the resilient stop plate 112 can be pressed to bend by the side wall at the second end of the resilient plate 300. When the plug pin 410 of the plug terminal 400 is inserted into the plug groove 310, the side wall at the second end of the resilient plate 300 is also supported by the resilient stop plate 112.When the distance H1 between the curved protrusion 320 and the side wall at the first end of the resilient sheet 300 is a constant value, the bending angle of the resilient stop plate 112 can be adjusted to vary a supporting force from the resilient stop plate 112 on the side wall at the second end of the resilient sheet 300, and in turn, to vary a compressive force from the curved protrusion 320 and the side wall at the first end of the resilient sheet 300 on the plug pin 410. Of course, the distance H1 between the curved protrusion 320 and the side wall at the first end of the resilient sheet 300, as well as the bending angle of the resilient stop plate 112, can also be adjusted together, so that the box terminal can be adapted to a resilient sheet on plug pin 410 coated with different materials.
