Description

Improved structure of retractable terminal electrical connector

This creation is an improvement in the structure of a retractable terminal electrical connector, and belongs to the technical field of retractable movable terminal structure of the electrical connector.

The first figure is a schematic cross-sectional view of a conventional retractable terminal electrical connector. As shown in the figure, the electrical connector 10 is composed of an insulating shell 20 combined with a retractable terminal 30. The retractable terminal 30 is It includes a cannula 301, the top of the cannula 301 has a slightly reduced diameter, and the space in the middle of the cannula 301 is provided with a spring 303 and a top contact pin 302 with a cylindrical shaft block 302a. The cylindrical shaft block 302a of the top contact pin 302 is continuously pushed by the spring 303, so that the top contact pin 302 protrudes on the top port of the sleeve 301 and is positioned for standby operation.

When the telescopic terminal 30 of the electrical connector 10 is in operation, it is in contact with the electrical connection contact 40 of another device, and is pressed and contacted. The top contact pin 302 is slightly lowered by the pressure, and at the same time the elasticity of the spring 303 The tension constantly pushes the cylindrical shaft block 302a of the contact pin 302 to ensure that the contact pin 40 of the contact pin 302 and the electrical connector of another device are in contact with each other.

However, the telescopic terminal 30 has a small volume, and the tube wall of the sleeve 301 in the component is extremely thin. In addition, the cylindrical shaft block 302a of the top contact pin 302 is in the sleeve 301, which is slightly off-axis. The reciprocating movement of the diameter causes the inner tube wall of the sleeve 301 to wear after repeated use, which makes the diameter of the inner tube of the sleeve 301 larger and the surface rough and smooth, so that the cylindrical shaft block 302a of the tip pin 302 is contacted, The off-axis rate of the moving path in the sleeve 301 is too large and the friction resistance is too large, causing the top contact pin 302 to not move normally and stuck in the sleeve 301 and it cannot be in contact with the electrical contact 40 of another device. And the damage.

This creation is an improved structure of a retractable terminal electrical connector, which includes: an insulating case, a movable terminal, a spring, and a conductive reed terminal. The insulating case is provided with a through-hole of the terminal shaft, and The upper caliber is smaller than the lower caliber, and the bottom of the insulating housing is located at the periphery of each terminal shaft hole, and a plurality of reed sockets communicating with the terminal shaft hole are recessed.

The movable terminal is a spring in which the diameter of the upper section is smaller than the diameter of the lower section. The top of the movable terminal is a top contact portion of a round surface. The movable terminal is inserted into the shaft hole of each terminal from the bottom of the insulating housing. Inside, the small diameter of the upper part of the terminal shaft hole can only be used for the small diameter part of the upper section of the movable terminal protruding from the upper and lower reciprocating movement of the insulating housing and the large diameter of the lower section of the movable terminal is located within the terminal shaft hole. The effect of detachment.

In addition, the conductive reed terminal is a base plate folded with several insert pieces and a welding leg. The insert piece is mainly provided with a reed, and the insert piece of the conductive reed terminal corresponds to the insulation case. The reed slot is inserted and positioned, and the reed of the insert frame of the conductive reed terminal is in contact with the top of the movable terminal, and the elasticity of the reed can be continuously adjusted by the thrust generated by the reciprocating movement of the movable terminal with a slightly off-axis. The stress activity does indeed hit the effect of the conduction of the movable terminal, and the situation that the movable terminal is stuck and cannot be reciprocated up and down.

The second figure is a combined perspective view of the structure improvement of the retractable terminal electrical connector. As shown in the figure, it includes: an insulating housing 50, a movable terminal 60, a spring 70, and a conducting spring terminal 80.

The insulating housing 50 (refer also to the third, fourth, fifth, and sixth drawings) is located according to the number of terminals and the terminal arrangement and distribution required by the electrical connector specifications. Opening terminal shaft holes 501 are formed. The upper diameter is smaller than the lower diameter, and the bottom of the insulating housing 50 is located at the periphery of each terminal shaft hole 501, and a plurality of reed slots 503 communicating with the terminal shaft hole 501 are recessed.

In addition, the movable terminal 60 (refer to the second, third, seventh, and eighth drawings) is a spring with a pipe diameter smaller than that of the lower section having a built-in spring 70, and the top of the movable terminal 60 is a round top contact portion. The movable terminal 60 is inserted into each terminal shaft hole 501 from the bottom of the insulating housing 50. The terminal The small diameter of the upper part of the shaft hole 501 (see also Figures 7 and 8) is only available for the small diameter part of the upper section of the movable terminal 60 protruding from the upper and lower parts of the insulating housing 50 and restricting the large tube of the lower section of the movable terminal 60 Those whose diameter is located in the terminal shaft hole 501 can not reciprocate.

In addition, (refer to the second, fifth, sixth, seventh, and eighth drawings), the conductive reed terminal 80 is formed by folding a plurality of insert pieces 801 and a welding leg 803 on a negative plate, and the insert piece 801 is mainly provided with The reed 802 is inserted and positioned with the inserting piece 801 of the conducting reed terminal 80 corresponding to the reed slot 503 of the insulating housing 50, and the reed 802 of the inserting piece 801 of the conducting reed terminal 80 and the movable terminal 60 contacts make the passer.

The eighth figure is a cross-sectional schematic diagram of the implementation of the structural improvement of the retractable terminal electrical connector. As shown in the figure, the movable terminal 60 of the electrical connector is pushed upward by the elastic tension of the spring 70 into the working position, and the conductive spring The reed 802 of the inserting piece 801 of the sheet terminal 80 and the movable terminal 60 are in electrical contact with each other. When the work is performed, the movable terminal 60 corresponds to the contact 40 of the electrical connector of the other device and is pressed and engaged. When conducting, the movable terminal 60 is slightly lowered by the pressure, and at the same time, the elastic tension of the spring 70 continuously pushes the movable terminal 60 to rise to ensure that the contact 40 of the movable terminal 60 and the electrical connector of another device are in contact with each other.
