Technical Field

[0001] The present invention relates to the technical field of connectors, and in particular to a contact piece for a connector and a connector. Background Art

[0002] In the connector industry, contacts have always been the most critical components, directly impacting the reliability of connector connection performance. Currently, most commonly used contacts are steel-clad copper structures. This involves first processing a conductive sheet into a multi-contact spring structure, then placing the sheet within an external support member, which then wraps around the sheet and secures the structure through subsequent processing. The complex manufacturing process for existing steel-clad copper contacts, coupled with the need for the external support member to wrap around the sheet and secure it in place, directly impacts contact production efficiency and cost. Summary of the Invention

[0031] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that in the description of the present invention, unless otherwise specified, the meaning of "multiple" is two or more; the orientation or position relationship indicated by the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail", etc. is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0032] See also Figure 1-7The present invention provides a contact for a connector, comprising a housing 1 and a contact assembly disposed in the housing 1 and having both front and rear ends for plugging and mating with a matching contact. The contact assembly comprises two symmetrically arranged spring assemblies 2, the spring assembly 2 comprising a first spring 21 and a second spring 22 disposed between the first spring 21 and the housing 1. The first spring 21 is provided with a plurality of first spring claws 211 spaced apart along its width at a front end, and a conductive clip 212 at a rear end. The conductive clip 212 is provided with a plurality of first through holes 213 spaced apart along its width. The second spring 22 has a second spring claw 221 disposed between adjacent first spring claws 211 at a front end, and a third spring claw 222 disposed in the first through hole 213 at a rear end. The matching contact is a matching pin. The first spring claw 211 is in conductive contact with the matching pin, and the second spring claw 221 and the third spring claw 222 are respectively in conductive contact with the matching pin.

[0033] Specifically, such as Figure 2 As shown, one side of the shell 1 is bent to form two contact parts 14, and the shell 1 is abutted against each other through the end planes of the two contact parts 14, and protrusions 15 are provided on both sides of the shell 1. The first folded edge 3 cooperates with the protrusion 15 to fix the reed assembly 2 in the plugging direction of the shell 1. The protrusion 15 ensures the stability of the connection between the reed assembly 2 and the shell 1. The shell 1 is made of steel material, and the first reed 21 and the second reed 22 are made of copper material. The first reed 21 and the second reed 22 are both formed by mold stamping and bending. After the first reed 21 and the second reed 22 are assembled into the reed assembly 2, the two reed assemblies 2 are installed in the shell 1 to realize the final forming of the contact piece. The processing technology is simple, the cost is low, and the assembly and production efficiency are high. In addition, compared with the existing external support member wrapping the conductive sheet and then fixed into one piece through subsequent processing, the first reed 21, the second reed 22 and the shell 1 of the present application can be processed separately and then assembled together. They are formed by modular split processing, which greatly improves the production efficiency of the contact piece.

[0034] Among them, Figure 1 and Figure 2As shown, the housing 1 is provided with a front limiting structure and a rear limiting structure, and the front limiting structure and the rear limiting structure are used to fix the spring assembly 2 in the insertion direction of the housing 1. The front limiting structure includes a bending portion 11 arranged at the front end of the housing 1 and bent into the housing 1. The bending portion 11 is two and symmetrically arranged at the front end of the housing 1. The front end of the first spring claw 211 is located in the bending portion 11 and abuts against the bending portion 11. There are two rear limiting structures on the upper and lower end surfaces of the housing 1. The rear limiting structure includes a second spring claw 211 arranged on the housing 1. Through hole 12, a first elastic component 13 is provided in the second through hole 12, one end of which is integral with the shell 1 and the other end of which is inwardly extended. The first elastic component 13 is used to be fixed with the reed assembly 2 when the reed assembly 2 is installed. When the reed assembly 2 is installed in the shell, the first elastic component 13 is against the first folded edge 3, which plays a limiting role and a rear limiting role. The present application realizes the fixation of the reed assembly in the shell insertion direction through the front limiting structure and the rear limiting structure, thereby ensuring the stability of the installation of the reed assembly.

[0035] In addition, if Figure 4 and Figure 5 As shown, first notches 4 are provided on both sides of the first reed 21, and first folded edges 3 located inside the first notches 4 are provided on the second reed 22 at positions corresponding to the first notches 4. This application ensures the stability of the combination of the first reed 21 and the second reed 22 by providing the first notch 4 on the first reed 21 and the first folded edge 3 on the second reed 22 corresponding to the first notch 4, and ensures the stability of the connection even in a vibration environment.
