DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] Refer to Figure 1As shown in the figure, the present utility model provides a technical solution: a circuit connector with high safety, including a connector body 1, and a protection device 2 is provided on the surface of the connector body 1. By setting the protection device 2, the effect of blocking the connection holes of the connector body 1 is achieved. When the connector body 1 is placed or not in use, since the connection holes of the connector body 1 are exposed to the air, dust or sundries from the outside will accumulate in the inner cavity of the connection holes of the connector body 1, resulting in poor contact and damage of the connector body 1 during use, thus improving the safety of the device. Adjusting devices 3 are provided on both sides of the connector body 1. By setting the adjusting devices 3, the effect of guiding the position during the installation of the connector body 1 and electronic components is achieved, avoiding the situation of contact point extrusion and bending damage during the installation process of the connector body 1 by the user, and improving the efficiency of the device.

[0029] Specifically, the following describes the specific settings and functions of its protection device 2 and adjusting device 3.

[0030] Refer to Figure 2 and Figure 3As shown, in this embodiment: the protective device 2 includes a U-shaped frame 201, the U-shaped frame 201 is fixedly connected to the surface of the connector body 1, the inner surface of the U-shaped frame 201 is fixedly connected to a long rod 202, the arc surface of the long rod 202 is rotatably connected to a rotating plate 203, one side of the rotating plate 203 is fixedly connected to a protective plate 204, the arc surface of the long rod 202 is sleeved with two torsion springs 208, and the two ends of the torsion spring 208 are respectively fixedly connected to the rotating plate 203 and the U-shaped frame 201. The torsion spring 208 drives the rotating plate 203 to rotate on the arc surface of the long rod 202, and the rotating plate 203 drives the protective plate 204 to rotate and fit with the surface of the connector body 1 and maintain a certain position state, thereby avoiding the protective plate 204 from opening during the carrying and movement of the connector body 1, thereby improving the stability of the device. A short rod 205 is fixedly connected to one side of the U-shaped frame 201, and a slide plate 206 is slidably connected to the arc surface of the short rod 205. A limiting rod 207 is fixedly connected to one side of the slide plate 206, and a limiting groove is provided on the side wall of the protective plate 204. The protective plate 204 drives the rotating plate 203 to rotate on the arc surface of the long rod 202, pushing the slide plate 206 to slide on the arc surface of the short rod 205. The slide plate 206 drives the limiting rod 207 to move until it is inserted into the limiting groove of the protective plate 204, thereby achieving the effect of limiting the position of the protective plate 204 and avoiding the automatic closing of the connector body 1 during use. The arc surface of the short rod 205 is covered with a spring 209, and the two ends of the spring 209 are respectively fixedly connected to the slide plate 206 and the U-shaped frame 201. The protective plate 204 is squeezed with the limiting rod 207, and the limiting rod 207 drives the slide plate 206 to slide on the arc surface of the short rod 205. At this time, the spring 209 is in a stretched state, until the limiting groove of the protective plate 204 is aligned with the position of the limiting rod 207, the elastic force of the spring 209 drives the slide plate 206 to slide on the arc surface of the short rod 205, and the slide plate 206 drives the limiting rod 207 to move and automatically insert into the limiting groove of the protective plate 204, thereby improving the quickness of the device. The size of the limiting rod 207 is adapted to the size of the limiting groove of the protective plate 204, and the end of the short rod 205 away from the U-shaped frame 201 is fixedly connected with a stopper 210. When the slide plate 206 is pulled to slide on the arc surface of the short rod 205, the slide plate 206 contacts the stopper 210, thereby preventing the user from pulling the slide plate 206 with too much force and causing it to be separated from the arc surface of the short rod 205, thereby improving the stability of the device.

[0031] Reference Figure 4As shown in the figure, specifically, the adjusting device 3 includes two semi-circular blocks 31, both of which are fixedly connected to both sides of the connector body 1. A screw rod 32 is threadedly inserted into the semi-circular block 31. One end of the screw rod 32 is rotatably connected to a guiding plate 33. A soft pad 34 is fixedly connected to the end of the guiding plate 33 away from the screw rod 32. A handle 35 is fixedly connected to the end of the screw rod 32 away from the guiding plate 33. An installation plate 36 is slidably inserted into the semi-circular block 31. One side of the installation plate 36 is fixedly connected to the guiding plate 33. Rotating the handle 35 drives the screw rod 32 to rotate within the semi-circular block 31. The screw rod 32 drives the guiding plate 33 to move. The guiding plate 33 drives the soft pad 34 to move. The guiding plate 33 drives the installation plate 36 to slide within the semi-circular plate, avoiding the situation where the guiding plate 33 rotates along with the rotation of the screw rod 32.

[0032] Working principle: When the staff needs to protect the connection holes of the connector body 1, by pulling the sliding plate 206 to slide on the arc surface of the short rod 205, the sliding plate 206 drives the limiting rod 207 to move until the limiting rod 207 disengages from the inner surface of the limiting groove of the protection plate 204. The torsion of the torsion spring 208 drives the rotating plate 203 to rotate on the arc surface of the long rod 202. The rotating plate 203 drives the protection plate 204 to move until the protection plate 204 automatically fits against the surface of the connector body 1, achieving the effect of covering the connection holes of the connector body 1. This avoids the situation where when the connector body 1 is placed or not in use, since the connection holes of the connector body 1 are exposed to the air, dust or debris from the outside will accumulate in the inner cavity of the connection holes of the connector body 1, resulting in poor contact and damage during the use of the connector body 1, improving the safety of the device.

[0033] When the staff needs to guide the position during the installation process of the connector body 1 and components, by rotating the handle 35, the screw rod 32 is driven to rotate within the semi-circular block 31. The screw rod 32 drives the guiding plate 33 to move. The guiding plate 33 drives the soft pad 34 to move. The guiding plate 33 drives the installation plate 36 to slide within the semi-circular plate, avoiding the situation where the guiding plate 33 rotates along with the rotation of the screw rod 32, achieving the effect of guiding the position during the installation process of the connector body 1 and electronic components, and avoiding the situation where the contacts are squeezed and bent and damaged during the installation process of the user, improving the speed of the device.
