Description

Technical Field

[0001] This utility model relates to a terminal connector socket. Background Technology

[0002] Terminal connectors and sockets, as fundamental electrical connection components, are widely used in industrial equipment, automotive electronics, communication systems, and many other fields. Their core function is to provide a stable and reliable mating interface for male plugs and to enable circuit conduction. In complex operating conditions such as outdoor equipment and new energy vehicles, connectors and sockets not only need to ensure excellent electrical connection performance, but also must possess outstanding sealing, shock resistance, and secure terminal fixing to resist the erosion and interference of environmental factors such as moisture, dust, and vibration.

[0003] Currently, common terminal connector sockets on the market typically improve their sealing and protection level by potting sealant inside the socket housing. However, existing potting sealants only apply sealant to the surface of the terminal connector. During use, some oil or liquid can seep into the terminal connector through gaps, causing damage to the terminals. Summary of the Invention

[0004] The purpose of this invention is to provide a terminal connector socket that can perform multiple seals, enhance the sealing effect, and ensure the operating environment of the terminal.

An outer frame 2 is fixedly provided on both the front and rear sides of the socket housing 11. An inner frame 3 is also fixedly provided on the front side of the socket housing 11. The inner frame 3 is located inside the outer frame 2. A plurality of through holes 4 through which the terminals 12 can pass are provided inside the inner frame 3. A plurality of terminals 12 are provided and are arranged one-to-one with each through hole 4. A plurality of limiting members 5 are also provided and are arranged one-to-one with each terminal 12. Each terminal 12 is limited in the corresponding through hole 4 by the limiting member 5. A first potting space 6 is formed inside the outer frame 2 on the front and rear sides of the socket housing 11 for potting adhesive to enter. A second potting space 7 is formed between the inner frame 3 and the outer frame 2 on the front side of the socket housing 11 for potting adhesive to enter.

[0019] The first potting space 6 and the second potting space 7 are connected. The outer wall of the inner frame 3 is provided with a guide slope for guiding the potting compound into the second potting space 7. The upper end of the guide slope extends toward the frame opening of the outer frame 2, and the lower end of the guide slope extends toward the socket housing 11. The potting compound enters the second potting space 7 from the first potting space 6 under the guidance of the guide slope.

[0020] The limiting member 5 includes a sleeve 51 fitted onto the terminal 12 and a spring piece 52 with one end fixedly mounted on the sleeve 51 and the other end extending outward. At least one spring piece 52 is provided. The inner wall of the through hole 4 is provided with a first extending annular groove 41 and a second extending annular groove 42 concentrically arranged with the through hole 4. The first extending annular groove 41 allows the spring piece 52 to enter. The side of the first extending annular groove 41 facing the rear side of the socket housing 11 forms a first boss with the socket housing 11, which can form a limiting engagement with the end of the spring piece 52 extending outward. The side of the second extending annular groove 42 facing the front side of the socket housing 11 forms a second boss with the socket housing 11. The terminal 12 is provided with a limiting protrusion 121 that can form a limiting engagement with the second boss. The terminal 12 is limited within the through hole 4 by the limiting engagement of the spring piece 52 with the first boss and the limiting engagement of the limiting protrusion 121 with the second boss.

[0021] A sealing ring 8 is provided in the inner frame 3 on the front side of the socket housing 11. The sealing ring 8 has a plurality of sealing holes 81 that correspond to each through hole 4 and allow the terminal 12 to pass through. The inner wall of the sealing hole 81 has a first sealing protrusion 811 and a second sealing protrusion 812 that extend along the extension direction of the sealing ring 8. The first sealing protrusion 811 and the second sealing protrusion 812 both act on the terminal 12 in the sealing hole 81. The outer wall of the sealing ring 8 acts on the inner wall of the inner frame 3.

[0022] The socket housing 11 is filled with glue in both the first glue-filling space 6 on the front side and the first glue-filling space 6 on the rear side of the socket housing 11.

[0023] When potting, the socket housing 11 has a first potting space 6 and a second potting space 7 on the front side. The potting compound first enters the first potting space 6 and then enters the second potting space 7. After the potting compound enters the second potting space 7 under the guidance of the guide slope, the potting compound in the second potting space 7 is held by the inner frame 3 and the outer frame 2, which ensures that the potting compound is stable in the outer frame 2. At the same time, if a small amount of oil seeps in from between the potting compound and the inner wall of the outer frame 2, it will first flow into this groove and will not flow directly into the inner frame 3 where the sealing ring 8 is located, which plays a certain protective role.

[0024] After the sealing ring 8 is installed in the inner frame 3, a third potting space is formed between the sealing ring 8 and the inner wall of the inner frame 3. While potting is being done in the first potting space 6 and the second potting space 7, the potting compound will enter the third potting space. Through the cooperation between the potting compound in the third potting space and the potting compound in the second potting space 7, the fixation of the potting compound is strengthened and delamination is prevented.

[0025] The socket shell is filled with glue on both sides, plus an oil-proof sealing ring, providing three layers of protection against oil.

[0026] The socket housing 11 has multiple mounting holes 13 through it, and each mounting hole 13 has a bushing 9 fixedly installed in it. The bushing 9 has a break, and due to the break, the bushing 9 has a certain deformation beam. The screw is installed in the bushing 9, which can prevent the screw torque from being too large and cracking the housing.

[0027] A waterproof gasket 10 is provided on the rear side of the socket housing 11. The waterproof gasket 10 has a clearance hole for the outer frame 2 on the rear side of the socket housing 11 to pass through. The waterproof gasket 10 also has a through hole corresponding to each mounting hole 13. The inner wall of the clearance hole acts on the outer wall of the outer frame 2.

[0028] The working principle of this utility model is as follows: the bushing 9 is pressed into the mounting hole 13 of the socket housing 11, and then the sealing ring 8 is installed in the inner frame 3 on the front side of the socket housing 11. After that, each terminal 12 is aligned with the through hole 4 and inserted into the through hole 4. The terminal 12 passes through the sealing hole 81 while being inserted into the through hole 4. During the insertion of the terminal 12 into the through hole 4, the spring piece 52 enters the first extension ring groove 41 and forms a limiting engagement with the first boss. The limiting protrusion 121 on the terminal 12 forms a limiting engagement with the second boss, and the terminal 12 is restricted in the through hole 4. Then, the waterproof gasket 10 is installed on the rear side of the socket housing 11, and then the outer frame 2 of the front and rear sides of the socket housing 11 is filled with glue. The potting glue in the outer frame 2 on the front side of the socket housing 11 enters the first potting space 6, the second potting space 7 and the third potting space. The potting glue in the outer frame 2 on the front side of the socket housing 11 is used to fill the first potting glue.
