The schematic structural diagram of the connector of this embodiment is shown in fig. 3, and the schematic explosion structural diagram of the connector of this embodiment is shown in fig. 4, which specifically includes: the device comprises a body 201, a dial handle 202, a first fixed terminal 203, a second fixed terminal 204 and a movable terminal 205; a first end of the first fixed terminal 203 and a first end of the second fixed terminal 204 are fixed inside the body 201, and a second end of the first fixed terminal 203 and a second end of the second fixed terminal 204 extend from the inside of the body 201 to the outside of the body 201; a first end of the movable terminal 205 is connected to a first end of the first fixed terminal 203; the body 201 is provided with an opening 206, the dial grip 202 being located at the opening 206 and part of the dial grip 202 being exposed out of the body 201 from the opening 206.

Specifically, when the dial 202 is pressed from the outside, the dial 202 retracts inside the body 201 and presses the movable terminal 205, and the second end of the movable terminal 205 is connected to the first end of the second fixed terminal 204; when the external pressure disappears, the second end of the movable terminal 205 is away from the first end of the second fixed terminal 204, the movable terminal 205 abuts against the dial grip 202, and part of the dial grip 202 is ejected out of the opening 206.

As shown in fig. 5, which is a partial schematic view of the connector of this embodiment disposed in an electronic device, the electronic device has a groove into which a stylus can be inserted, the connector of this embodiment is located on a sidewall of the groove, and a pull handle 202 of the connector protrudes from a surface of the sidewall, wherein a concave engaging portion 108 for fixing the stylus is located at a front end of the stylus. When a touch control pen is inserted into the groove from right to left, the right end of the shifting handle 202 always bears the force of the touch control pen, the shifting handle 202 converts the stress of the right end into downward pressure, the shifting handle 202 compresses downward, and the movable terminal 205 is pressed, so that the second end of the movable terminal 205 is connected with the first end of the second fixed terminal 204, the first fixed terminal 203 is connected with the second fixed terminal 204, and signals and current can be transmitted between the first fixed terminal 203 and the second fixed terminal 204; when the stylus 107 is pulled out of the groove and the engaging portion 108 at the front end of the stylus reaches the pulling handle 202, the pulling handle 202 is popped up to the engaging portion 108, when the user continues to pull the stylus 107 out of the groove, the left end of the pulling handle 202 is subjected to the force of the stylus 107, at the moment, the pulling handle 202 converts the force of the left end into downward pressure, and the pulling handle 202 compresses downward; when the stylus 207 is separated from the handle 202, the movable terminal 205 gradually returns to the uncompressed state, and at this time, the second end of the movable terminal 205 gradually moves away from the first end of the second fixed terminal 204, and the handle 202 returns to the original state under the support of the movable terminal 205, that is, the handle 202 is located at the opening 206 and a part of the handle 202 is exposed out of the body 201 from the opening 206.

In addition, the above description is only given by taking the stylus as an example, and in practical applications, the stylus may be other devices that can be inserted into the electronic device.

In the present embodiment, the dial 202 may be connected to the movable terminal 205, or may not be connected to the movable terminal 205, and may be provided according to actual needs, and the present embodiment is not particularly limited.

In the dial grip 202 disposed at the opening of the body 201 in this embodiment, no matter the direction of the external force applied to the dial grip 202, the dial grip 202 will retract into the body 201 under the action of the external force and press the movable terminal 205, so that the second end of the movable terminal 205 is connected to the first end of the second fixed terminal 204, and thus the first fixed terminal 203 is connected to the second fixed terminal 204, and the transmission of signals and current between the first fixed terminal 203 and the second fixed terminal 204 is realized. That is to say, the connector of the present embodiment can be converted into a downward pressure no matter which direction the lever 202 is subjected to, and therefore, the connector of the present application can withstand pressures in different directions, and can prevent the connector from being damaged when the connector needs to withstand forces in different directions.

In one embodiment, the handle 202 matches the size of the opening where the handle 202 may snap fit; when the dial 202 is not stressed, the dial 202 is clamped at the opening, when the dial 202 is squeezed by external force, the dial 202 can be retracted into the body 201, and when the dial 202 is supported by the movable terminal 205, the dial 202 can be restored to the original position.

In one embodiment, a slide way extending along the opening direction is disposed on the side wall of the opening, and the handle 202 is provided with a sliding portion slidably disposed in the slide way. Through the arrangement, the dial 202 can slide at the opening, so that the dial 202 can press the movable terminal 205.

A connection between the lever 202 and the movable terminal 205 is provided. In another embodiment, the paddle 202 may be integrally formed with the movable terminal 205.

In an embodiment, a limiting member extends from a surface of the latch away from the dial grip 202, the width of the limiting member is greater than the width of the latch, and under the action of the limiting member, when the positioning hole 208 of the movable terminal 205 is engaged with the latch 207, the movable terminal 205 is blocked from moving outward, so that the movable terminal 205 and the dial grip 202 can be further fixed, and the stability of connection between the movable terminal 205 and the dial grip 202 is improved.

In one embodiment, as shown in fig. 7, which is a schematic structural view of the movable terminal, the movable terminal 205 has an arcuate structure 209, and the arcuate structure 209 is proximate to the first end of the movable terminal 205. By providing the arcuate structure 209 so that the movable terminal 205 has a certain elasticity, the movable terminal 205 can be prevented from being deformed when being pressed. Specifically, the arcuate structure 209 may provide some elasticity to the movable terminal 205, which may prevent the movable terminal 205 from deforming when being pressed.

In one embodiment, the portion of the lever 202 exposed from the body 201 is arc-shaped. Through the arrangement, when the external structure pushes the dial grip 202 from left to right or from right to left, the arc-shaped structure can enable the external structure to push the dial grip 202 smoothly until the dial grip 202 is pressed into the body 201, so that the dial grip 202 is pushed into the body 201 more easily, and the difficulty of pushing the dial grip 202 into the body 201 is simplified.

Through the arrangement, the friction force between the dial handle 202 and an external structure is small, so that the dial handle 202 is pushed into the body 201 more easily, and the difficulty of pushing the dial handle 202 into the body 201 is further simplified.

In one embodiment, as shown in fig. 8, which is a schematic diagram of an exploded structure of the connector of this embodiment, the connector further includes a housing 210; the body 201 is provided with a connection groove in which a first end of the first fixed terminal 203, a first end of the second fixed terminal 204, and the movable terminal 205 are all disposed; the opening is arranged on the side wall of the connecting groove; the size of shell and the size of body 201 match, and the shell covers the spread groove. Specifically, the connecting grooves of the body 201 are used for accommodating each device, and after each device is placed according to a preset position, the connecting grooves are covered by the shell, so that each device is sealed inside the body 201, each device inside the connector is guaranteed not to be interfered by other elements, and the stability of the connector structure is improved.
