Description

Technical Field

[0001] This invention relates to a punched socket assembly, belonging to the field of electrical connector technology. Background Technology

[0002] High-current connectors are widely used in various fields. Contact terminals and current-carrying capacity are the key performance indicators for connectors and the basis for connector design. High-current terminals are the core components of high-voltage connectors, significantly impacting circuit performance. Achieving stable and efficient electrical connections is a crucial indicator of excellent contact performance. Currently, most stamped socket assemblies use assembly-type spring contacts and shell conductors, resulting in limited current-carrying capacity and short mating life. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the present invention aims to provide a punched socket assembly that solves the problems of limited current carrying capacity and low insertion / removal life in existing technologies.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A punched socket assembly includes a housing conductor and spring contacts, the spring contacts being symmetrically arranged inside the housing conductor;

[0006] The spring sheet has multiple spaced arc-shaped contact areas along the insertion direction. Cantilever beams are symmetrically arranged in the intervals of the arc-shaped contact areas, and shock-absorbing beams are symmetrically connected on both sides of the arc-shaped contact areas.

[0007] One end of the cantilever beam is connected to the spring clip, and the other end extends into a cantilever state. When the insert is inserted, the cantilever end of the cantilever beam contacts the outer shell conductor.

[0008] The damping beam is shaped like a "∧". The connection between the damping beam and the arc-shaped contact area is normally suspended. When the insert is inserted, the connection comes into contact with the outer shell conductor.

[0009] Furthermore, the aforementioned outer conductor includes an upper shell and a lower shell;

[0010] The upper and lower shells are interlocked, forming a clearance space in the middle, and the spring pieces are symmetrically fixed inside the clearance space.

[0011] Furthermore, both the upper and lower ends of the aforementioned spring are provided with spring fixing holes, and both the upper and lower housings are provided with spring mounting holes that are compatible with the spring fixing holes. The outer shell conductor and the spring are riveted together through the spring mounting holes and the spring fixing holes.

[0012] Furthermore, spring mounting holes are provided in both the 90° and 180° directions along the upper and lower shells. By changing the positional relationship between the spring and the outer shell conductor during riveting, the spring can be assembled in both the 90° and 180° directions within the outer shell conductor.

[0013] Furthermore, the aforementioned spring sheet also has symmetrical flange structures at both the upper and lower ends.

[0014] Furthermore, the area of ​​the aforementioned damping beam region is smaller than that of the arc-shaped contact region.

[0015] The beneficial effects achieved by this invention are as follows:

[0016] 1. By using the damping beam structure and cantilever beam, when the insert is inserted, the lower contact point of the damping beam and the contact point of the cantilever beam are squeezed by the insertion force of the spring plate and then contact the outer shell to guide the flow, thereby increasing the flow path and improving the current carrying capacity.

[0017] 2. The “∧” shape of the shock-absorbing beam can prevent the spring from yielding after repeated insertion and removal, thus affecting contact and improving insertion and removal life;

[0018] 3. The spring clips are riveted in different directions to allow the inserts to be inserted in different directions. Attached Figure Description

Detailed Implementation

[0030] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0031] This embodiment discloses a socket assembly, such as Figure 1 and Figure 2 As shown, it includes an outer shell conductor 1 and a spring piece 2. The outer shell conductor 1 includes an upper shell 12 and a lower shell 13. The upper shell 12 and the lower shell 13 are interlocked, forming a clearance space 14 in the middle. One side of the plane of the spring piece 2 is connected to the upper shell 12 and the lower shell 13 respectively, and is symmetrically fixed inside the clearance space 14.

[0032] Combination Figure 7 and Figure 8 It can be seen that the spring piece 2 has spring piece fixing holes 213 at both the upper and lower ends, and spring piece mounting holes 11 that match the spring piece fixing holes 213 are provided along the 90° and 180° directions of the upper housing 12 and the lower housing 13. The outer shell conductor 1 and the spring piece 2 are riveted together through the spring piece mounting holes 11 and the spring piece fixing holes 213, so that the spring piece 2 and the outer shell conductor 1 are reliably connected and can conduct larger current. The clearance space 14 has openings on different sides, providing two insertion directions for the insert 3. By changing the positional relationship between the spring piece 2 and the outer shell conductor 1 during riveting, the insert 3 can be inserted and removed in the 90° (longitudinal) and 180° (lateral) directions of the outer shell conductor 1. When the insert 3 is inserted in the 180° direction, the positional relationship between the insert 3 and the outer shell conductor 1 is as follows. Figure 3 When insert 3 is inserted at a 90° angle, the positional relationship between insert 3 and outer shell conductor 1 is as follows: Figure 6 .

[0033] Combination Figure 8 , Figure 9 and Figure 10The spring piece 2 has multiple arc-shaped contact areas 215 along the insertion direction. An arc-shaped contact point 217 is located at the peak of each arc-shaped contact area 215. Shock-absorbing beams 214 are symmetrically connected to both sides of the arc-shaped contact areas 215. The shock-absorbing beams 214 are in the shape of a "∧". The connection between the arc-shaped contact areas 215 and the shock-absorbing beams 214 forms the lower contact point 212 of the shock-absorbing beam. The top of the shock-absorbing beam 214 is the upper limit point 216. Under normal conditions, the lower contact point 212 of the shock-absorbing beam is suspended. When the spring piece is inserted, the lower contact point 212 of the shock-absorbing beam contacts the outer conductor 1. The area of ​​the shock-absorbing beam 214 is smaller than that of the arc-shaped contact areas 215. The shock-absorbing beam is smaller than the main contact portion, resulting in a smaller insertion and extraction force during insertion and extraction. The inherent elasticity of the shock-absorbing beam 214 prevents the spring piece from yielding after repeated insertion and extraction, thus affecting contact. Arc-shaped contact areas 215 are spaced apart, and cantilever beams 211 are symmetrically arranged in the gaps between adjacent arc-shaped contact areas 215. Each cantilever beam 211 has an independent support point. One end of the cantilever beam 211 is connected to the spring piece 2, and the other end extends into a cantilever state. A cantilever beam contact point 218 is provided at the bottom peak of the cantilever end of the cantilever beam 211. When the insert is inserted, the cantilever beam contact point 218 contacts the outer shell conductor 1. The upper and lower ends of the spring piece 2 are also symmetrically provided with flange structures 21, which serve as guides and limiters.

[0034] During the insertion process, the insert 3 is guided by the flange structure 21. After the insertion is completed, the upper limit point 216 of the shock-absorbing beam and the flange structure 21 will prevent the insert 3 from deflecting too much.

[0035] The insert 3 contacts the spring 2 through the arc-shaped contact area 215. The spring 2 and the outer shell are riveted and bonded together to conduct current. At the same time, the contact point 212 under the shock-absorbing beam is squeezed and bonded to the outer shell conductor 1 when the insert 3 is inserted to conduct current. In addition, the contact point 218 of the cantilever beam contacts the outer shell conductor 1 to conduct current.

[0036] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
