Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to an outer conductor structure. Background Technology

[0002] With the continuous development of electrical connectors and the intensification of industry competition, the structure of the outer conductor has also become more diversified. The outer conductor is mainly responsible for forming an electrical connection through contact points and mating terminals, providing a reliable path for energy or signal transmission, and realizing the basic function of electrical connectors in forming electrical connections.

[0003] To ensure contact stability, the outer conductor is usually composed of a base and a spring arm structure, while the contact is located on the spring arm. During the mating process, the spring arm deformation provides holding force to ensure contact stability. The reliability of this contact can be verified by test items in relevant standards such as USCAR-2 and TC.

[0004] To meet relevant standards, the common external conductor structure of automotive miniature connectors is such that the connection of the spring arm is located on the side relatively far from the insertion end, while the contact is suspended on the side relatively close to the insertion end. In order to reduce the risk of pin collapse, a protrusion structure is added to the insertion end for limiting. This structural design leads to complex stamping process, many control indicators, and low production efficiency. Moreover, if the protrusion structure is not designed properly, it is very easy to cause pin collapse defects. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an outer conductor structure that is simple in structure, easy to manufacture, and has high production efficiency, while effectively preventing pin collapse problems.

[0006] This utility model is achieved through the following technical solution:

[0007] An outer conductor structure includes an outer conductor substrate and a plurality of elastic arms, wherein the plurality of elastic arms are distributed in the circumferential direction of the outer conductor substrate, and the axial direction of the elastic arms is consistent with the axial direction of the outer conductor substrate;

[0008] The spring arm has a first axial end and a second axial end. The first axial end is connected to the outer conductor substrate and is located near the port of the outer conductor substrate. The second axial end is suspended and located away from the port of the outer conductor substrate.

[0009] The spring arm has a contact point, which is located near the second axial end and is used to make contact with the mating connector.

[0010] Furthermore, the spring arm is integrally formed and includes a connecting part, a transition part and an abutting part connected in sequence. The connecting part, the transition part and the abutting part are arranged in sequence along the assembly direction of the mating connector, and the connecting part is connected to the outer conductor substrate, and the contact is formed on the abutting part.

[0011] Furthermore, the transition portion bends along the assembly direction toward a direction away from the outer conductor substrate.

[0012] Furthermore, the contact point is formed by the outward protrusion of the spring arm in the radial direction.

[0013] Furthermore, a contact area is formed at the highest point of the contact point.

[0014] Furthermore, the outer conductor substrate is ring-shaped, and the outer conductor substrate includes a substrate body and a narrow ring body formed by the substrate body protruding from the outside to the inside. The narrow ring body is located at the port of the outer conductor substrate, and the plurality of elastic arms are distributed in the circumferential direction of the outer conductor substrate.

[0015] Furthermore, the substrate body covers the projection of the elastic arm onto the outer conductor substrate.

[0016] Furthermore, the outer conductor substrate also includes a transition ring connecting the substrate body and the narrow ring body. The narrow ring body, the transition ring, and the substrate body are arranged sequentially along the assembly direction of the mating connector, and the outer diameter of the transition ring gradually increases along the assembly direction.

[0017] Furthermore, the spring arm is formed by opening a groove in the base body.

[0018] Furthermore, the plurality of elastic arms are spaced apart in the circumferential direction of the base body.

[0019] Compared with existing technologies, the advantages of this utility model are:

[0020] 1. By connecting the first axial end of the spring arm to the outer conductor base and placing it near the port of the outer conductor base, and suspending the second axial end of the spring arm and placing it away from the port of the outer conductor base, when the mating connector is inserted along the assembly direction, even if the mating connector is inserted at an angle relative to the outer conductor structure, the mating connector can be guided and corrected by the spring arm, and finally make stable contact with the contacts, ensuring the stability of the product and avoiding the occurrence of pin collapse problems.

[0021] 2. By placing the spring arm on the substrate body of the outer conductor substrate, and ensuring that the substrate body can cover the projection of the spring arm onto the outer conductor substrate. In existing technologies, the projection of the spring arm onto the outer conductor substrate falls within a narrow ring, and additional protrusion structures are designed for restraint and protection of the spring arm. Compared to existing designs, this solution has a simpler structure, eliminates the need for additional protrusion structures, saves fabrication steps, optimizes the process, and reduces labor and time costs.

Detailed Implementation

[0025] The following detailed, non-limiting description of the utility model's technical solution, in conjunction with preferred embodiments and accompanying drawings, further illustrates the invention. In this description, it should be understood that terms such as "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. Furthermore, the terms "" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "" or "second" may explicitly or implicitly include at least one of that feature. In this description, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0026] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides an outer conductor structure including an outer conductor substrate 100 and a plurality of elastic arms 200. The plurality of elastic arms 200 are distributed in the circumferential direction of the outer conductor substrate 100, and the axial direction of the elastic arms 200 is consistent with the axial direction of the outer conductor substrate 100.

[0027] like Figure 1 As shown, the spring arm 200 has a first axial end 201 and a second axial end 202. The first axial end 201 is connected to the outer conductor base 100 and is located near the port 101 of the outer conductor base 100. The second axial end 202 is suspended and located away from the port 101 of the outer conductor base 100. When the mating connector 400 mates with the outer conductor structure along the assembly direction X, the mating connector 400 passes sequentially through the port 101 of the outer conductor base 100, the first axial end 201 of the spring arm 200, and the second axial end 202 of the spring arm 200. When the two are assembled in place, the spring arm 200 abuts against the internal terminal of the mating connector 400 due to its elasticity, so as to form a stable electrical contact between the mating connector 400 and the outer conductor structure.

[0028] A contact 300 is formed on the spring arm 200, located near the second axial end 202, for contacting the mating connector 400. When the mating connector 400 is inserted along the assembly direction X, even if it is inserted at an angle relative to the outer conductor structure, it can be guided and corrected by the spring arm 200, and finally make stable contact with the contact 300, ensuring product stability and preventing pin collapse. Compared to existing structures, this embodiment does not require an additional protrusion structure for limiting movement. Therefore, compared to existing designs, the outer conductor structure is simpler, the parts are easier to manufacture, production efficiency is higher, and pin collapse is effectively prevented.

[0029] like Figure 2 As shown, the spring arm 200 is integrally formed and includes a connecting portion 210, a transition portion 220, and an abutment portion 230 connected in sequence. The connecting portion 210, the transition portion 220, and the abutment portion 230 are arranged sequentially along the assembly direction X of the mating connector 400. The connecting portion 210 is connected to the outer conductor base 100, and the contact 300 is formed on the abutment portion 230. When the mating connector 400 mates with the outer conductor structure along the assembly direction X, the mating connector 400 passes through the connecting portion 210, the transition portion 220, and the abutment portion 230 in sequence, ensuring stable mating and preventing pin breakage caused by tilted insertion of the mating connector 400.

[0030] The transition portion 220 bends along the assembly direction X toward the direction away from the outer conductor substrate 100. The transition portion 220 has a certain deformation capability. During the mating process between the mating connector 400 and the outer conductor structure, the deformation force of the transition portion 220 ensures that the spring arm 200 remains in contact with the mating connector 400 and guarantees the stability of the contact between the two.

[0031] Preferably, the contact 300 is formed by the outward protrusion of the spring arm 200 in the radial direction, and the contact area is formed at the highest point of the contact 300. No additional soldering of contact points is required, simplifying the process and reducing costs. When the mating connector 400 and the outer conductor structure are properly mated, the contact 300 maintains stable contact with the mating connector 400.

[0032] In this embodiment, the outer conductor substrate 100 is ring-shaped and includes a substrate body 110 and a narrow ring 130 protruding from the substrate body 110 from the outside to the inside. The narrow ring 130 is located at the port 101 of the outer conductor substrate 100, and multiple elastic arms 200 are distributed in the circumferential direction of the outer conductor substrate 100. Furthermore, the multiple elastic arms 200 are spaced apart in the circumferential direction of the substrate body 110.

[0033] Furthermore, the substrate 110 covers the projection of the spring arm 200 onto the outer conductor substrate 100. In the prior art, the projection of the spring arm 200 onto the outer conductor substrate 100 falls within the narrow ring 130, and an additional protruding structure is designed for restraint to protect the spring arm 200. Compared to the existing design, this solution has a simpler structure, eliminates the need for an additional protruding structure, saves fabrication steps, optimizes the process, and reduces labor and time costs.

[0034] The outer conductor substrate 100 also includes a transition ring 120 connecting the substrate body 110 and the narrow ring body 130. The narrow ring body 130, the transition ring 120, and the substrate body 110 are arranged sequentially along the assembly direction X of the mating connector 400, and the outer diameter of the transition ring 120 gradually increases along the assembly direction X. During the mating process of the mating connector 400 along the assembly direction X, the transition ring 120 passes through the narrow ring body 130, the transition ring 120, and the substrate body 110 in sequence. By setting the transition ring 120, the mating connector 400 can move naturally and smoothly from the relative position of the narrow ring body 130 to the substrate body 110, avoiding jamming or interference between the mating connector 400 and the outer conductor structure during the assembly process.

[0035] In this embodiment, the spring arm 200 is formed by the base body 110 by opening a groove 111.

[0036] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
