Description

Technical Field

[0001] This invention relates to the field of connectors, and more specifically to a surface mount connector terminal. Background Technology

[0002] The most crucial component in connector products is the contact element, which plays a vital role in achieving stable electrical transmission and current carrying. Currently, surface-mount terminals are cheaper and more efficient to manufacture than machined terminals, representing a general trend in the industry. However, surface-mount terminals also have their drawbacks. Firstly, they offer insufficient protection for the contact areas; the elastic contact portion of surface-mount terminals is prone to deformation after a drop, leading to a reduction in electrical contact points. Secondly, the guidance provided by hole terminals for pin terminals is not ideal. Thirdly, inserting pin terminals at a certain angle may cause insertion difficulties or deformation of the spring contacts. Summary of the Invention

[0003] The purpose of this invention is to improve upon existing technology by proposing a structure that can prevent the contact end from deforming during the mating process, thereby reducing the contact effect and improving conductivity.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A chip connector terminal includes a wiring terminal and a contact terminal. The contact terminal includes an axially arranged support member and an elastic member disposed within the support member. The same-direction ends of the support member and the elastic member are connected to the wiring terminal, and the other ends of the support member and the elastic member are respectively suspended and floating.

[0005] In the above technical solution, the support member and the elastic member are symmetrically connected to both sides of the contact terminal.

[0006] In the above technical solution, the support member and the elastic member each have independent spring pieces, and the entire connector terminal structure from the outside to the inside consists of the contact piece of the support member, the spring piece of the elastic member, and the wiring terminal.

[0007] In the above technical solution, the front end of the elastic element is a finger-shaped structure, and the front end of the finger-shaped structure is set as a bent structure. Several grooves are provided along the bent structure, the purpose of which is to increase the number of contact points during the insertion process.

[0008] In the above technical solution, a bending opening structure is provided at the connection between the front end and the rear end of the elastic element. The purpose is to enable the front end of the elastic element to be turned outward during the insertion process, so as to ensure the smooth insertion process.

[0009] In the above technical solution, a convex bulge is provided on the inner side of the front end of the support member. The front end of the convex bulge has an angle, which can guide the smooth insertion of the mating ends during the mating process.

[0010] In the above technical solution, a square groove is provided on the side of the support member, and the front end of the square groove has an angle to ensure sufficient holding force with the outer shell.

[0011] In the above technical solution, protrusions of different lengths are respectively provided on both sides of the front end of the terminal block, serving as a foolproof and limiting function.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: This invention assembles the elastic element and the terminal block into one unit through assembly. The structural limit is achieved by the interaction between the support and the elastic element. Current conduction is achieved by the effective contact between the bent finger structure at the front end of the elastic element and the female terminal and the surface contact between the rear end of the elastic contact element and the connecting terminal. This greatly increases the contact area and ensures the conductivity. The suspended and floating structural design allows for a tighter clamping force between the elastic element and the terminal block, ensuring that there is no risk of loosening of the mating terminals and guaranteeing the mating effect.

Detailed Implementation

[0014] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0015] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0016] like Figure 1 As shown, the connector terminal in this embodiment mainly includes a wiring terminal 4, a support member 1, and an elastic member 2, wherein one end of the support member 1 and the elastic member 2 is fixedly connected to the wiring terminal 4, and the other end of the support member 1 and the elastic member 2 is suspended and floating.

[0017] like Figure 2 As shown, in this embodiment, both the support member 1 and the elastic member 2 adopt a symmetrical structure. The support member 1 includes two independent support pieces, which adopt a symmetrical compression structure to clamp the terminal 4 in the middle. The elastic member 2 includes two independent spring pieces, which adopt a symmetrical compression structure to clamp the support member 1 in the middle. The support member 1, the elastic member 2, and the terminal 4 are fixedly connected by riveting.

[0018] like Figure 3 The diagram shows the structure of the spring sheet of elastic element 2. A through hole 2-1 is provided at the rear end of the spring sheet for assembly connection. The front end of the spring sheet is configured with a finger-like structure, and the end of each finger is configured with a bent portion 2-4. A groove 2-3 is provided at the bent portion of the bent portion 2-4, and the groove direction of the groove 2-3 is consistent with the orientation of the finger-like structure. A bending opening 2-2 is provided at the connection between the rear end and the front end of the spring sheet, allowing the front end of the spring sheet to expand along the direction of the bending opening 2-2 when symmetrical.

[0019] like Figure 4 The structure of the spring piece of the support member 1 is shown. A protrusion 1-1 is provided on the inner side of the front end of the spring piece. The front end of the protrusion 1-1 has a bevel, which plays a guiding role during the insertion of the female terminal. A square groove 1-2 is also provided on the front end of the spring piece. The front end of the square groove 1-2 has a bevel structure, which can increase the holding force with the housing mounting. A through hole is provided on the rear end of the spring piece for connecting the spring piece and the terminal 4.

[0020] like Figure 5 The diagram shows the structure of the terminal block 4. A through hole is provided on the front end of the terminal block 4 for connecting with the support member 1 and the elastic member 2. On both sides of the front end of the terminal block 4, there are bosses 4-1 of different sizes. The bosses 4-1 can play the role of preventing reverse insertion and limiting the position in the housing. A rivet hole 4-2 is provided on the rear end of the terminal block 4 for connecting the nut 5 and the wiring.

[0021] like Figure 2 As shown, in this embodiment, during assembly, the two second spring pieces of the elastic member 2 are clamped onto the terminal 4, and then the two first spring pieces of the support member 1 are clamped onto the elastic member 2. The three are fixedly connected by rivets to form a clamping end.

[0022] The key point of this embodiment is the cooperation between the support member 1 and the elastic member 2. The support member 1 also has a bending opening on the spring piece, which corresponds to the bending opening 2-2 on the elastic member. This has the function of protecting the elastic contact member from bending outward and deforming, which would reduce the number of contact points.

[0023] In this embodiment, the elastic element 2 is disposed inside the support element 1, with the terminal 4 at the very center. Current conduction is achieved through the effective contact between the bent finger-like structure at the front end of the elastic element 2 and the female terminal, and the surface contact between the rear end of the elastic element 2 and the terminal.

[0024] This invention is not limited to the specific embodiments described above. The invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
