Description

TECHNICAL AREA

[0001] The present utility model relates to the technical field of connection, in particular a socket contact and a connector. STATE OF THE ART

[0002] As a core component of electrical connectors, socket contacts are widely used in electronic devices, the automotive industry, power supply systems, and other fields. Their performance directly impacts the stability and reliability of the connections. Socket contacts typically consist of a contact body and a spring leaf, and the deformation of the spring leaf generates a clamping force. This secures the pin contact and maintains the electrical connection, thus meeting conductivity requirements.

[0003] In related technologies, the left side of the spring leaf's elastic arm is positioned to the right of the socket contact's elastic arm's support point, creating an asymmetric force structure. During insertion / removal or in vibrating environments, the spring leaf tends to oscillate vertically due to this force imbalance, resulting in unstable contact pressure and detachment. For example, if external tensile forces or vibration loads occur, the spring leaf's elastic deformation can exceed design thresholds, leading to separation between the pin and socket contacts and consequently, circuit interruption or poor contact.

[0020] As in Fig. Figures 1 to 3 illustrate an embodiment of the present utility model providing a socket contact comprising a contact body 1 and a spring leaf 2, wherein the contact body 1 comprises a base 11 and two contact arms 12 connected to the base 11, wherein the base 11 is provided with two first grooves, and wherein the two first grooves are located on two sides of the contact arm 12 in a first direction, and wherein two side walls of the first grooves each form a first pivot point 111 and a second pivot point 112 in a second direction, and wherein the two contact arms 12 are spaced apart from each other and arranged opposite each other along the second direction, and wherein the two contact arms 12 are used to clamp the pin contacts; and wherein the spring leaf 2 comprises two elastic arms 21 and two connecting elements 22.wherein the two elastic arms 21 are spaced apart from each other and arranged opposite each other along the first direction, and wherein the two connecting elements 22 are spaced apart from each other and arranged opposite each other along a third direction, and wherein the two connecting elements 22 are each connected between the two elastic arms 21, and wherein the two connecting elements 22 are uniquely assigned to the two contact arms 12, and wherein a first slot 23 is formed between the two elastic arms 21, and wherein a second slot 23 is formed between the two connecting elements 22, which is connected to the first slot 24, and wherein the two contact arms 12 are successively inserted into the first slot 23 and the second slot 24 along the third direction,and wherein the two elastic arms 21 project into the first groove associated with the base 11 and can be limited between the first pivot point 111 and the second pivot point 112, and wherein each elastic arm 21 is located on a side of the corresponding first pivot point 111 facing the other side of the first pivot point 111, and wherein the two connecting elements 22 can each bear against the corresponding contact arms 12 along the third direction, so that the two contact arms 12 clamp the pin contacts, and wherein the first direction, the second direction and the third direction are perpendicular to each other in pairs.

[0021] When the spring leaf 2 and the contact body 1 are joined together, the contact arms 12 of the contact body 1 can be inserted successively into the first slot 23 and the second slot 24, with the two contact arms 12 bearing against the two connecting elements 22, and with the pin contact being able to be inserted between the two contact arms 12; the two connecting elements 22 of the spring leaf 2 clamp the two contact arms 12 in place, so that the two contact arms 12 can clamp the pin contact in order to prevent poor contact between the socket contact and the pin contact and thus improve the overall electrical conductivity;Simultaneously, the two elastic arms 21 of the spring leaf 2 can project into the first groove of the base 11, and by means of the first pivot point 111 and the second pivot point 112 of the first groove, the elastic arms 21 are limited to effectively prevent vertical vibration of the spring leaf 2 and to improve the stability of the bushing contact.

[0022] Optionally, the contact body 1 is made of a conductive material, in particular a copper alloy with high electrical conductivity.

[0023] Optionally, the leaf spring 2 is made of highly elastic stainless steel.

[0024] Furthermore, the contact arms 12 are V-shaped, each having a second groove, and the two connecting elements 22 are each located in the second grooves of the respective contact arms 12 and press against the contact arms 12. This arrangement further ensures positional stability between the spring leaf 2 and the contact body 1.

[0025] Furthermore, a clamping groove is provided on the elastic arm 21, wherein a locking projection is arranged on each of the two side walls of the first groove in the first direction, and wherein the two clamping grooves are each clamped with the two locking projections in order to limit the movement of the spring leaf 2 relative to the contact body 1 along the third direction.

[0026] The interlocking engagement between the clamping grooves and the locking projections effectively prevents unintentional movement of the spring leaf 2 in the third direction due to vibrations, shocks, or insertion / removal forces. This ensures a fixed relative position between the spring leaf 2 and the contact body 1. In combination with the limitation of the elastic arm 21 caused by the side walls of the first groove, the stability of the bushing contact is further improved.

[0027] Furthermore, the contact body 1 is a one-piece molded component. This one-piece molding eliminates the assembly process between the base 11 and the contact arm 12 and reduces the risk of poor contact due to loose components, thus ensuring long-term stability of the clamping force of the pin contact. Additionally, deformation or breakage of the contact arm 12 is less likely to occur with repeated insertion and removal, thereby extending its service life.

[0028] Furthermore, the leaf spring 2 is a one-piece molded component. The elastic arm 21 and the connecting element 22 are formed in a single operation, thus avoiding weak points that arise from separate assembly. This ensures uniform force transmission when the elastic arm 21 deforms under load, thereby reducing the risk of fracture due to stress concentrations. Moreover, the separate manufacturing of the elastic arm 21 and the connecting element 22 with subsequent welding or riveting is eliminated, thus reducing the number of process steps and lowering labor and equipment costs, making it suitable for mass production.

[0029] Furthermore, the elastic arms 21 are U-shaped, as shown in Fig. 2 shown, wherein the elastic arm 21 has a first free end and a second free end, wherein the two ends of one connecting element 22 are each connected to the first free ends of the two elastic arms 21, while the two ends of the other connecting element 22 are each connected to the second free ends of the two elastic arms 21.

[0030] The two connecting elements 22, which are connected to each other via the two elastic arms 21, exhibit elasticity in the second direction. When the two elastic arms 22 are subjected to an external force, they move away from each other, which facilitates the mounting of the spring leaf 2 onto the contact body 1. At the same time, the spring leaf 2 has a frame structure, which reduces the material required for its manufacture and thus lowers costs, while simultaneously enabling a lightweight design of the socket contact.

[0031] Furthermore, two guide arms 13 are arranged at the base 11, wherein the two guide arms 13 are spaced apart from each other and arranged opposite each other along the first direction, and wherein the two contact arms 12 are located between the two guide arms 13, and wherein the guide arms 13 extend along the third direction, and wherein the two guide arms 13 each bear against the two elastic arms 21.

[0032] The two guide arms 13 can completely enclose the two elastic arms 21 in the first direction, thus ensuring stable relative positioning between the spring leaf 2 and the contact body 1. This guarantees stable clamping of the pin contact by the contact body 1. At the same time, the guide arms 13 provide corrective guidance for inserted pin contacts. Furthermore, the number of contact points between the socket contact and the pin contact can be increased by having the guide arms 13 bear against the pin contact, thereby improving electrical conductivity.

[0033] Furthermore, a projection 131 is arranged at one end of the guide arm 13 facing away from the base 11, and this projection rests against the elastic arm 21. This arrangement allows the projections 131 on both guide arms 13 to exert a clamping function. The projection 131 limits the relative position between the spring leaf 2 and the contact body 1, thereby ensuring the stability of the bushing contact.

[0034] Furthermore, the projection 131 is provided with a guide surface that guides the elastic arm 21 so that it is inserted between the guide arm 13 and the contact arm 12. In particular, this guide surface has an arc-shaped configuration.

[0035] This arrangement facilitates the smooth insertion of each elastic arm 21 between the corresponding guide arm 13 and contact arm 12, thereby improving the accessibility of the insertion process.

[0036] Furthermore, several contact arm groups are arranged on the contact body 1, wherein the several contact arm groups are spaced apart along the first direction, and wherein the socket contact comprises several spring leaves 2, and wherein the several spring leaves 2 are uniquely assigned to the several contact arm groups; and wherein each contact arm group comprises two contact arms 12, which are spaced apart from each other and arranged opposite each other along the second direction, and wherein each contact arm group is inserted into the corresponding spring leaf 2 along the third direction. This configuration can satisfy different width requirements of the pin contacts with varying specifications.

[0037] For example, as in Fig.Figure 1 shows the contact arm assembly and the spring leaf 2 each provided in a quantity of 2. In other embodiments, the number of contact arm assemblies and spring leaves 2 can be adapted according to practical requirements, with three, four or more being possible.

[0038] One embodiment of the present utility model provides a connector comprising the aforementioned socket contact.
