Description

Technical Field

[0001] This utility model belongs to the technical field of mating electrical connectors, and particularly relates to a mating electrical connector. Background Technology

[0002] In addition to meeting general performance requirements, electrical connectors must also meet the following requirements: good contact, reliable operation, and convenient maintenance. Their reliability directly affects the normal operation of the entire circuit and is related to the safety of the entire host. In the current technology, electrical connectors mainly achieve circuit connection through the mutual plugging of male and female plugs, and most of the related male and female plugs on the market are directly plugged in.

[0003] For example, patent document with authorization announcement number "CN111613935B" discloses an electrical connector, a mating electrical connector, and an electrical connector assembly. The mating electrical connector includes a body portion and a first mating portion located at the front end of the body portion. The electrical connector also has a second mating portion and an outer sleeve that extends forward beyond the second mating portion and forms a receiving cavity at the front end of the second mating portion. The body portion includes a first body portion and a second body portion located at the front end of the first body portion and smaller in size than the first body portion. The first mating portion and the second mating portion are mated together, and the second body portion is received in the receiving cavity. The receiving cavity cooperates with the second body portion. This patented technical solution enhances the mechanical connection strength between the electrical connector and the mating electrical connector.

[0004] However, in the prior art, electrical connectors generally include a socket assembly and a plug assembly. The socket assembly includes a housing, and the plug assembly includes a head housing. The housing and head housing generally contain multiple conductive pins. When the housing and head housing are connected together, the corresponding conductive pins are mated together to achieve power transmission. If there is a radial deviation in the relative position between the conductive pin and the housing, or between the conductive pin and the head housing, the mating of the conductive pins will be misaligned, affecting the reliability of the electrical connection. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a mating electrical connector.

[0006] This utility model provides a mating electrical connector, including a socket assembly and a plug assembly. The socket assembly includes a housing and a first stationary contact pin, which is fixedly connected to the housing. The plug assembly includes a head shell, a second stationary contact pin, a moving contact pin, a guide sleeve, and a spring claw. The second stationary contact pin is fixedly connected to the head shell. The surface of the second stationary contact pin has a receiving hole. The guide sleeve and the spring claw are disposed in the receiving hole. The moving contact pin is supported by an elastic element at the edge of the opening of the receiving hole. One end of the moving contact pin also passes through the guide sleeve, and one end of the spring claw is fixedly connected to the guide sleeve. The other end of the spring claw abuts against the outer peripheral surface of the moving contact pin. When the housing and the head shell are connected together using a locking assembly, the other end of the moving contact pin simultaneously abuts against the surface of the first stationary contact pin.

[0007] The elastic element is a cylindrical helical compression spring.

[0008] The number of spring claws is multiple, and the multiple spring claws are distributed in a circumferential array around the perimeter of the guide sleeve.

[0009] The guide sleeve and the spring claw are manufactured as a single piece.

[0010] The mating electrical connector also includes a wire. The surfaces of the first stationary contact pin and the second stationary contact pin are provided with grooves. One end of the wire is welded and fixed in the groove, and the other end of the wire extends out of the head shell or the base shell.

[0011] The first stationary contact pin and the housing, and the second stationary contact pin and the head housing are both bonded together with epoxy adhesive.

[0012] The first stationary contact, the second stationary contact, and the moving contact are all cylindrical in shape, and multiple positioning steps are provided on the outer circumferential surface of the first stationary contact, the second stationary contact, or the moving contact.

[0013] Both ends of the moving stylus are spherical.

[0014] Limiting holes are provided on the left and right sides of the head shell, and the locking assembly includes bolts, which are screwed onto the left and right sides of the base shell respectively, and the bolts pass through the limiting holes.

[0015] The surface of the second stationary contact pin is also provided with an exhaust hole, which is connected to the receiving hole.

[0016] The beneficial effects of this utility model are as follows: When the locking assembly is used to connect the seat shell and the head shell together, the moving contact pin and the first stationary contact pin are synchronously connected, realizing the electrical connection. Since a guide sleeve and a spring claw are provided between the moving contact pin and the receiving hole, the guide sleeve guides the movement direction of the moving contact pin, reducing the radial deviation during the movement of the moving contact pin, while the spring claw corrects or compensates for the radial deviation of the moving contact pin, so that the moving contact pin can always move along its axial direction, thereby reliably connecting the moving contact pin and the first stationary contact pin, ensuring reliable electrical connection.

Detailed Implementation

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings, but the scope of protection claimed is not limited to the description. This utility model provides a mating electrical connector, such as Figures 1 to 10As shown, the device includes a socket assembly 1 and a plug assembly 2. The socket assembly 1 includes a housing 3 and a first stationary contact pin 4, which is fixedly connected to the housing 3. The plug assembly 2 includes a head housing 5, a second stationary contact pin 6, a moving contact pin 7, a guide sleeve 8, and a spring claw 9. The second stationary contact pin 6 is fixedly connected to the head housing 5. The surface of the second stationary contact pin 6 is provided with a receiving hole 10. The guide sleeve 8 and the spring claw 9 are disposed in the receiving hole 10. The moving contact pin 7 is supported at the edge of the opening of the receiving hole 10 by an elastic element 11. One end of the moving contact pin 7 also passes through the guide sleeve 8, and one end of the spring claw 9 is fixedly connected to the guide sleeve 8. The other end of the spring claw 9 abuts against the outer peripheral surface of the moving contact pin 7. When the housing 3 and the head housing 5 are connected together using a locking assembly, the other end of the moving contact pin 7 simultaneously abuts against the surface of the first stationary contact pin 4.

[0020] When the locking assembly is used to connect the housing and the head housing together, the moving contact pin and the first stationary contact pin are synchronously connected, realizing the electrical connection. Since a guide sleeve and a spring claw are provided between the moving contact pin and the receiving hole, the guide sleeve guides the movement direction of the moving contact pin, reducing the radial deviation during the movement of the moving contact pin, while the spring claw corrects or compensates for the radial deviation of the moving contact pin, so that the moving contact pin can always move along its axial direction, thereby reliably connecting the moving contact pin and the first stationary contact pin, ensuring reliable electrical connection.

[0021] Specifically, the elastic element 11 is a cylindrical helical compression spring. There are multiple spring claws 9, arranged in a circumferential array around the guide sleeve 8. The guide sleeve 8 and the spring claws 9 are integrally manufactured. Using the technical solution of this utility model, the spring claws 9 are made of elastic metal material, capable of uniformly applying a corrective force around the moving contact pin 7, ensuring that the moving contact pin 7 always moves along its axial direction, thus reducing the radial deviation of the moving contact pin 7 relative to the head shell 5.

[0022] In addition, the mating electrical connector also includes a wire 12. The surfaces of the first stationary contact 4 and the second stationary contact 6 are both provided with grooves 13. One end of the wire 12 is soldered and fixed in the groove 13, and the other end of the wire 12 extends out of the head shell 5 or the seat shell 3. The first stationary contact 4 and the seat shell 3, and the second stationary contact 6 and the head shell 5 are all bonded and fixed together with epoxy adhesive 14.

[0023] Furthermore, the first stationary contact 4, the second stationary contact 6, and the moving contact 7 are all cylindrical in shape, and multiple positioning steps 15 are provided on the outer circumferential surface of the first stationary contact 4, the second stationary contact 6, or the moving contact 7. By adopting the technical solution of this utility model and providing the positioning steps 15, the assembly error between the first stationary contact 4, the second stationary contact 6, and the moving contact 7 and the housing 3 or the head housing 5 is reduced, further improving the reliability of the electrical connection.

[0024] Specifically, both ends of the moving contact pin 7 are spherical. Limiting holes 16 are provided on the left and right sides of the head housing 5. The locking assembly includes bolts, which are screwed onto the left and right sides of the base housing 3, and the bolts pass through the limiting holes 16. By adopting the technical solution of this utility model, since both ends of the moving contact pin 7 are spherical, the contact between the moving contact pin 7 and the first stationary contact pin 4 is a point-to-surface contact. Even if the moving contact pin 7 has a slight radial deviation, it can still ensure the minimum contact requirement between the moving contact pin 7 and the first stationary contact pin 4, further improving the reliability of the electrical connection.

[0025] In addition, the surface of the second stationary contact pin 6 is provided with an exhaust hole 17, which is connected to the receiving hole 10. Using the technical solution of this utility model, when the second stationary contact pin 6 and the head shell 5 are both bonded and fixed together with epoxy adhesive 14, the air remaining inside the epoxy adhesive 14 can be discharged through the exhaust hole 17 and the receiving hole 10, thereby making the epoxy adhesive 14 solidify and ensuring a tight connection between the second stationary contact pin 6 and the head shell 5.
