Description

Technical Field

[0001] This utility model relates to a terminal structure, specifically an automotive power pin socket terminal structure. Background Technology

[0002] Automotive power connectors are interface components used in automotive electrical systems to connect power sources and devices. They typically consist of multiple metal pins and corresponding sockets for power transmission or signal control.

[0003] The existing automotive power connector terminal structure is poorly designed and overly complex. The existing terminal structure is not securely fixed to the housing due to its small contact area, making it prone to loosening after prolonged use. Furthermore, the female contact pieces used for connecting to external terminals typically lack reinforcement. When an external terminal is inserted, pressure is applied to the female contact pieces, which can deform after repeated insertion and removal, thus shortening their lifespan. Therefore, the inventors have improved the terminal structure of the automotive power connector. Utility Model Content

[0004] The purpose of this utility model is to provide an automotive power connector terminal structure. This automotive power connector terminal structure has the advantages of simple structure and reasonable design. Through the design of the U-shaped fixing groove, the contact area between the terminal body and the housing is larger, and the connection is tighter after assembly. It is not easy to loosen during use. In addition, the female head support piece supports the female head main contact pieces at both ends, so that the pressure on the two female head main contact pieces is distributed at both ends of the female head support piece. At the same time, the connecting piece effectively supports the female head support piece, reducing the pressure on the female head main contact pieces themselves and extending their service life. This solves the problems mentioned in the above technical background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automotive power supply pin socket terminal structure, which includes a housing and several terminal bodies fixed on the housing. Each terminal body includes an upper contact and a lower contact fixed on the upper contact. A reinforcing rib is provided between the upper and lower contacts. The upper contact includes a female end and an upper folded edge fixed on the female end. A contact structure is provided at the end of the female end away from the lower contact. The lower contact includes a male end and a lower folded edge fixed on the male end. A base is connected at the end of the male end away from the female end. The width of the base gradually decreases from top to bottom, that is, the width of the base at the end away from the male end is smaller, which facilitates fixing it on the circuit board of the automotive power supply.

[0006] Preferably, the contact structure includes two oppositely arranged female main contact pieces and a female support piece disposed between the two female main contact pieces, and the female support piece and the two female main contact pieces are all connected to the female end.

[0007] Preferably, the female head support plate has a connecting plate and a connecting beam fixed on the connecting plate at one end near the male head end, and the two ends of the connecting beam are respectively fixed to the two upper folded edges.

[0008] Preferably, the female head support piece and the two female head main contact pieces are all inclined, and the two female head main contact pieces approach each other from bottom to top.

[0009] Preferably, there are two upper folded edges and two lower folded edges, with the two upper folded edges symmetrically arranged on the female end and the two lower folded edges symmetrically arranged on the male end.

[0010] Preferably, there are two reinforcing ribs, which are arranged in parallel. Both reinforcing ribs are fixed between the female end and the male end. The two reinforcing ribs are used to reinforce the joint between the female end and the male end. The female end, the male end, and the reinforcing ribs are all fixed to the rubber shell, so that the joint between the female end and the male end is better fixed to the rubber shell.

[0011] Preferably, the housing includes a main housing and a limiting protrusion fixed on the main housing. Several insertion holes are provided on the main housing, and a fixing groove is provided through each of the insertion holes. The fixing grooves are all U-shaped, and the female end, male end and reinforcing rib are all fixed in the fixing grooves.

[0012] Preferably, the number of sockets is divided into two groups, and the two groups of sockets are distributed at both ends of the main housing.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model provides an automotive power connector terminal structure, which includes a housing and several terminal bodies fixed to the housing. The overall structure is simple and reasonably designed. The terminal body includes an upper contact and a lower contact fixed to the upper contact. A reinforcing rib is provided between the upper and lower contact. The upper contact includes a female end and an upper folded edge fixed to the female end. The lower contact includes a male end and a lower folded edge fixed to the male end. The housing includes a main housing and a component fixed to the main housing. The limiting protrusion has several insertion holes on the main housing, and each insertion hole has a through-hole with a fixing groove. The fixing grooves are all U-shaped. The female end, male end, and reinforcing rib are all fixed in the fixing groove. The upper folded edge reinforces the female end, the lower folded edge reinforces the male end, and the reinforcing rib reinforces the joint between the female end and the male end. This makes the overall structure of the terminal body more stable, and the contact area between the terminal body and the U-shaped fixing groove is larger, resulting in a tighter connection after assembly. It is less likely to loosen during use and is suitable for widespread use.

[0014] 2. The contact structure in this utility model includes two oppositely arranged female main contact pieces and a female support piece disposed between the two female main contact pieces. The two ends of the female support piece are respectively close to the two female main contact pieces. The end of the female support piece near the male end is provided with a connecting piece and a connecting beam fixed on the connecting piece. The two ends of the connecting beam are respectively fixed to the two upper folded edges. The connecting piece is close to the bottom of the female support piece. When the female support piece is under pressure, it will contact the connecting piece, so that the connecting piece can support the female support piece. When the two female main contact pieces are connected to external terminals, both female main contact pieces are in contact with the female support piece, so that the pressure on the two female main contact pieces is distributed at both ends of the female support piece. At the same time, the connecting piece effectively supports the female support piece and reduces the pressure on the female main contact piece itself, thus extending its service life.

Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0030] Please see Figure 1 The present invention provides an embodiment of an automotive power pin socket terminal structure, which includes a housing 2 and several terminal bodies 1 fixed on the housing 2. The technical principle of the structure is prior art and will not be described in detail here.

[0031] Please see Figure 2 The terminal body 1 includes an upper contact 11 and a lower contact 12 fixed on the upper contact 11, and a reinforcing rib 13 is provided between the upper contact 11 and the lower contact 12.

[0032] Please see Figure 3The upper contact 11 includes a female end 111 and an upper folded edge end 112 fixed to the female end 111. A contact structure 113 is provided at the end of the female end 111 away from the lower contact 12. The lower contact 12 includes a male end 121 and a lower folded edge end 122 fixed to the male end 121. There are two upper folded edges 112 and two lower folded edges 122. The two upper folded edges 112 are symmetrically arranged on the female end 111, and the two lower folded edges 122 are symmetrically arranged on the male end 121. A base 123 is connected to the end of the male end 121 away from the female end 111. The width value gradually decreases from top to bottom, that is, the width value of the end of the base 123 away from the male end 121 is smaller, which makes it easier to fix it on the circuit board of the automotive power supply. In addition, there are two reinforcing ribs 13, and the two reinforcing ribs 13 are arranged in parallel. Both reinforcing ribs 13 are fixed between the female end 111 and the male end 121. The two reinforcing ribs 13 are used to reinforce the joint between the female end 111 and the male end 121. The female end 111, the male end 121 and the reinforcing ribs 13 are all fixed on the housing 2, so that the joint between the female end 111 and the male end 121 is better fixed on the housing 2.

[0033] Please see Figure 4 The contact structure 113 includes two oppositely arranged female main contact pieces 1131 and a female support piece 1132 disposed between the two female main contact pieces 1131. The female support piece 1132 and the two female main contact pieces 1131 are all connected to the female end 111. The two ends of the female support piece 1132 are respectively close to the two female main contact pieces 1131. Therefore, when the two female main contact pieces 1131 are connected to external terminals, both female main contact pieces 1131 are in contact with the female support piece 1132, so that the pressure on the two female main contact pieces 1131 is distributed at both ends of the female support piece 1132, and the pressure on the female main contact pieces 1131 themselves is reduced, thus resulting in a longer service life.

[0034] Please see Figures 5 to 6 The female head support plate 1132 is provided with a connecting plate 1133 and a connecting beam 1134 fixed on the connecting plate 1133 at one end near the male head end 121. The two ends of the connecting beam 1134 are fixed to the two upper folded ends 112 respectively. The connecting plate 1133 is close to the bottom of the female head support plate 1132. When the female head support plate 1132 is under pressure, it will contact the connecting plate 1133. Therefore, the connecting plate 1133 can support the female head support plate 1132, thereby ensuring that the female head main contact plate 1131 and the female head support plate 1132 can maintain their original shape after repeated insertion and removal, and are not prone to deformation.

[0035] Please see Figures 7 to 8The female head support piece 1132 and the two female head main contact pieces 1131 are all inclined, and the two female head main contact pieces 1131 approach each other from bottom to top.

[0036] Please see Figure 9 The housing 2 includes a main housing 21 and a limiting protrusion 22 fixed on the main housing 21. Several insertion holes 211 are provided on the main housing 21. The insertion holes 211 are divided into two groups, and the two groups of insertion holes 211 are distributed at both ends of the main housing 21. A fixing groove 212 is provided through each of the insertion holes 211. The fixing groove 212 is U-shaped. The female end 111, the male end 121 and the reinforcing rib 13 are all fixed in the fixing groove 212. The female end 111 and the male end 121 are U-shaped with the reinforcing rib 131, so they can be well fixed in the fixing groove 212.

[0037] Please see Figure 10 After the terminal body 1 and the housing 2 are assembled, the base 123 is located below the main housing 21.

[0038] Please see Figure 11 After the terminal body 1 and the housing 2 are assembled, the female main contact piece 1131 and the female support piece 1132 are both disposed in the socket 211.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
