DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] Example 1: Please refer to Figure 1-Figure 6 , the existing connector is not convenient for adjusting the contact force between the crimping end and the cable or the male terminal when in use, which leads to poor electrical contact stability between the crimping end and the cable or the male terminal. In order to solve this technical problem, this embodiment discloses the following technical content;

[0043] A connector with adjustable contact force, comprising an upper insulating shell 1, a lower insulating shell 2 is installed at the lower end of the upper insulating shell 1, a pull ring 3 is connected to the left end of the upper insulating shell 1, a front interface 4 is opened on the left side of the lower insulating shell 2, and a rear interface 5 is opened on the right side of the upper insulating shell 1 and the lower insulating shell 2; a fixing block 6 is fixedly connected to the inner side of the upper insulating shell 1 and the lower insulating shell 2, and a connecting part 7 is fixedly connected to the side of the fixing block 6, and a conductive terminal is installed on the connecting part 7, and a support member 8 is installed on the inner top of the fixing block 6, and the support member 8 is A crimping end 9 for crimping the cable end is provided at the bottom, and the crimping end 9 is fixed to the side of the connecting portion 7. An adjusting component 10 for adjusting the pressing force of the crimping end 9 on the cable end is installed at the upper end of the fixed block 6. A conductive plate 11 is provided below the crimping end 9, and the front and rear sides of the conductive plate 11 are connected to each other through a built-in spring 12 and the fixed block 6, and a conductive spring 13 is fixedly connected to the middle part of the lower end of the conductive plate 11. The adjusting component 10 is a rod-shaped component with threads, and the middle part of the adjusting component 10 and the fixed block 6 are threaded.

[0044] When the connector is used, the end of the cable is inserted into the interior of the fixed block 6 through the front interface 4. At this time, the adjusting component 10 is rotated. After the adjusting component 10 is rotated, it can move downward. After the adjusting component 10 moves downward, it can push the wire pressing end 9, so that the wire pressing end 9 moves downward and applies pressure to the conductive plate 11. At this time, the conductive plate 11 is subjected to pressure and moves downward synchronously with the conductive spring piece 13. The contact between the conductive spring piece 13 and the end of the cable is utilized to connect the circuit. The adjusting component 10 is a rod-shaped component with threads. Therefore, the height of the wire pressing end 9 can be adjusted by rotating the adjusting component 10 forward or reversely, thereby changing the contact force of the conductive spring piece 13 on the end of the cable according to actual needs, thereby improving the electrical contact stability.

[0045] Embodiment 2: The technical content disclosed in this embodiment is a further improvement on the above embodiment 1. When the current of the existing connector is overloaded or too low during use, it is not convenient to automatically cut off the power, which may cause the connection to heat up seriously or even burn after the current is overloaded. When the current is too low, the supply voltage may be reduced to below the rated value due to the serious shortage of supply current, making the device unstable or even unable to work normally. In order to solve this technical problem, this embodiment discloses the following technical content, such as Figure 2 and Figure 5-Figure 10 As shown;

[0046] A power-off mechanism 14 for automatic protection in case of abnormal current is installed inside the conductive plate 11, and limiter components 15 for auxiliary compression of the cable ends after power failure are installed on the left and right sides of the conductive plate 11. The front and rear outer walls of the conductive plate 11 and the inner wall of the fixed block 6 fit each other, and the conductive plate 11 forms an elastic telescopic structure through the built-in spring 12 and the fixed block 6, and the conductive spring 13 is located in the middle of the lower end of the conductive plate 11. The power-off mechanism 14 includes a guide column 141, and the guide column 141 is installed through the middle part of the conductive plate 11. The middle part of the guide column 141 and the conductive spring sheet 13 are located on the same vertical straight line, and the upper end of the guide column 141 is fixedly connected with a clamping block 143 below the left and right sides. The upper end of the guide column 141 is connected to the inner top of the conductive plate 11 through an auxiliary spring 142, and a moving rod 144 is arranged below the clamping block 143. The moving rod 144 is provided with a pressure groove 145, and the moving rod 144 is connected to the inside of the conductive plate 11 through a reset spring 147. One end of the moving rod 144 extending out of the conductive plate 11 is fixedly connected with a magnetic metal block 146, and an electromagnet 148 is arranged on the outer side of the magnetic metal block 146, and the electromagnet 148 is fixedly installed in the middle of the front and rear sides of the fixed block 6. The guide column 141 forms an elastic telescopic structure through the auxiliary spring 142 and the conductive plate 11, and the clamping blocks 143 fixedly connected to the lower left and right sides of the upper end of the guide column 141 are set to an isosceles triangle structure. The moving rod 144 and the conductive plate 11 are slidably connected, and the longitudinal section of the pressure groove 145 in the middle of the moving rod 144 is set to a "V" shape. The limiting assembly 15 includes an adjusting frame 151, and the adjusting frame 151 is slidably installed inside the conductive plate 11. The sliding direction of the adjusting frame 151 is the front-to-back direction. The adjusting frame 151 is connected to the inside of the conductive plate 11 through a spring, and a vertical rod 152 is installed through the middle of the adjusting frame 151. The lower end of the vertical rod 152 is fixedly connected to an insulating pressure plate 153, and the vertical rod 152 is connected to the adjusting frame 151 through a clamping spring 154. The rear end of the adjusting frame 151 and the end of the moving rod 144 located inside the conductive plate 11 are fixedly connected to a linkage magnetic block 155 with opposite magnetic properties. A positioning block 156 is provided at the upper end of the vertical rod 152, and a guide groove 157 is provided in the middle of the positioning block 156. The positioning block 156 is fixedly installed on the top end of the inner part of the conductive plate 11. The vertical rod 152 and the adjustment frame 151 are slidably connected, and the upper end of the vertical rod 152 is set as a spherical structure. The spherical end above the vertical rod 152 fits in the middle of the guide groove 157 in the initial state, and the longitudinal section of the guide groove 157 is set as an arc structure.

[0047] When the connector is in normal use, the electromagnet 148 generates a magnetic attraction force on the magnetic metal block 146 at the end of the moving rod 144 after being energized. At this time, the moving rod 144 moves toward the outside of the conductive plate 11. After the moving rod 144 moves, the beveled edge of the pressure groove 145 on it squeezes the clamping block 143 below the upper end of the guide column 141. At this time, the clamping block 143 is subjected to force to move the guide column 141 upward. After the upward movement, the lower end of the guide column 141 releases the squeezing of the conductive spring 13, and the conductive spring 13 is reset and separated from the cable end. There is a short power outage in this process until the center line of the pressure groove 145 on the moving rod 144 and the center line of the clamping block 143 are located on the same vertical straight line, and the moving rod 144 is in a flat and stationary state. After the center lines of the pressure groove 145 and the clamping block 143 are located on the same vertical straight line, the guide column 141 is reset and rebounded under the action of the auxiliary spring 142. The reset guide column 141 squeezes the conductive spring sheet 13 again, and the conductive spring sheet 13 contacts the cable end again. After that, the circuit is always in a connected state to perform normal work. When the current is too large or too small, the excessive current will cause the magnetic force of the electromagnet 148 to increase, while the excessive current will cause the magnetic force of the electromagnet 148 to decrease. When the current is too large, the magnetic attraction of the electromagnet 148 to the magnetic metal block 146 at the end of the moving rod 144 becomes larger. At this time, the moving rod 144 continues to move toward the outside of the conductive plate 11. After the moving rod 144 moves, it can utilize the "V"-shaped pressure groove 14 5 pushes the clamping block 143 on the guide column 141, and the lower end of the guide column 141 that moves upward releases the squeeze on the conductive spring sheet 13, and the conductive spring sheet 13 is reset and separated from the cable end, and a power-off state is formed at this time. When the current is too small, the magnetic attraction force of the electromagnet 148 on the magnetic metal block 146 at the end of the moving rod 144 becomes smaller, and the moving rod 144 is reset for a distance under the action of the reset spring 147. At this time, the oblique edge of the pressure groove 145 on the reset moving rod 144 can also squeeze and push the clamping block 143, and the clamping block 143 that is pushed upward will also drive the guide column 141 to move upward, thereby releasing the squeeze on the conductive spring sheet 13, and then the conductive spring sheet 13 is reset and separated from the cable end to form a power-off state. In normal power-on use, after the moving rod 144 moves, when the center line of the pressure groove 145 thereon and the center line of the clamping block 143 are located on the same vertical straight line, the linkage magnetic block 155 on the moving rod 144 and the linkage magnetic block 155 on the adjusting frame 151 attract each other. Thereafter, after the current is abnormal, when the moving rod 144 moves, it can drive the adjusting frame 151 and the vertical rod 152 to move synchronously. After the adjusting frame 151 moves, the spherical end above the vertical rod 152 is squeezed by the arc-shaped guide groove 157. At this time, the vertical rod 152 is squeezed and drives the insulating pressing plate 153 to move downward synchronously. The insulating pressing plate 153 that has moved downward can press the end of the cable in the power-off state to ensure the stability of the cable, so that after the subsequent current returns to normal,The conductive spring 13 can contact and conduct electricity at the same position of the cable end.
