Description

Technical Field

[0001] The utility model relates to the technical field of electrical appliances, in particular to a circuit connector which is convenient for assembly and disassembly. Background Art

[0002] Connectors build bridges of communication between blocked or isolated circuits in a circuit, thereby allowing current to flow and the circuit to achieve its intended function. An integrated circuit is a miniature electronic device or component that uses a certain process to interconnect the transistors, resistors, capacitors, inductors and other components and wiring required in a circuit, and is made on a small piece or several small pieces of semiconductor wafers or dielectric substrates, and then packaged in a tube shell to become a miniature structure with the required circuit function. Traditional integrated circuits (ICs) are generally connected to circuit boards by welding, but poor pin welding will result in bridging, cold welding and other undesirable phenomena, which seriously affects the welding quality of the conductive channel, makes the conduction unreliable, and the integrated circuit (IC) may be damaged due to poor control of the welding temperature. The welding method is not conducive to repair and replacement.

[0003] An existing patent (publication number: CN217983730U) discloses an integrated circuit IC connector that is easy to assemble and disassemble. The mounting plate is removed from the surface of the mounting box by screws, and the damaged circuit device is taken out from the inside of the mounting box and replaced with a new one; then the user rotates the lead screw, and the lead screw rotates to engage the thread groove of the moving block, so that the moving block drives the supporting block to move up and down inside the limit groove to adjust the height of the circuit device.

[0004] However, the above technical solution still has certain defects. When a damaged circuit device needs to be replaced, the staff needs to successively unscrew the screws at the four corners of the mounting plate, remove it, and then replace it with a new circuit device. The disassembly or installation process is rather cumbersome, time-consuming and labor-intensive. Therefore, a circuit connector that is easy to disassemble and assemble is proposed.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0027] The following describes an embodiment of the utility model based on its overall structure.

[0028] A circuit connector that is easy to assemble and disassemble, such as Figure 1-6 As shown, it includes a base body 100, and bolts 110 are threadedly engaged at the four corners of the bottom of the base body 100. A mounting box 120 is fixedly installed on the upper surface of the base body 100. A mounting plate 130 is provided on the front side of the mounting box 120. The mounting plate 130 is fixedly connected to the mounting box 120 through a clamping assembly 300. An adjustment assembly 200 is provided inside the mounting box 120; the clamping assembly 300 includes a clamping slot 310 opened at the four corners of the front side of the mounting box 120, and an active chamber 320 is opened on one side of the inner cavity of the clamping slot 310. A trapezoidal block 330 is slidably connected inside the movable chamber 320, a spring 340 is fixedly installed between one side of the trapezoidal block 330 and the inner wall of the movable chamber 320, a connecting column 350 is fixedly installed on one side of the spring 340 of the trapezoidal block 330, the other end of the connecting column 350 extends through to the outside of the installation box 120, L-shaped rods 370 are fixedly installed at the four corners of the back side of the installation plate 130, the L-shaped rod 370 matches the slot 310, and a pull rod 360 is fixedly installed at one end of the connecting column 350 located on the outside of the installation box 120.

[0029] The operator picks up the mounting plate 130 and aligns the L-shaped rod 370 with the slot 310, and then pushes it in. As the L-shaped rod 370 is pushed in, the trapezoidal block 330 is squeezed to move into the active chamber 320, thereby squeezing the spring 340. When the L-shaped rod 370 is fully inserted to the bottom of the inner cavity of the slot 310, the trapezoidal block 330 loses its squeezing force, and the elastic force of the spring 340 itself is used to push the trapezoidal block 330 to reset and move to the back of the L-shaped rod 370 to complete the fixed limit, so that the mounting plate 130 is fixed to the mounting box 120 and the installation is completed. When the damaged circuit board 160 needs to be replaced, the pull rod 360 is pulled to drive the trapezoidal block 330 to move into the active chamber 320, thereby releasing the limit on the L-shaped rod 370, and then the mounting plate 130 is removed, which is convenient for replacement and maintenance.

[0030] Please refer to Figure 1 , Figure 2 and Figure 6As shown, a wiring slot 140 is provided on the front side of the installation box 120, a threaded hole is provided on the top of the installation box 120, and a limiting device 150 is provided in the threaded hole. The limiting device 150 includes a threaded rod 151, a rotating block 152 is fixedly installed on the top of the threaded rod 151, a pressure plate 153 is fixedly connected to the bottom of the threaded rod 151, and an insulating layer 154 is fixedly connected to the bottom of the pressure plate 153. Slide grooves are provided on both sides of the inner cavity of the installation box 120, and a slider 180 is slidably connected in the slide groove, a circuit board 160 is fixedly installed on one side of the slider 180, and a contact 170 is provided on the top of the circuit board 160.

[0031] During operation, the user passes the lead wire through the wiring slot 140 into the interior of the installation box 120, and places it on the contact 170 on the top of the circuit board 160, and then rotates the threaded rod 151. The threaded rod 151 rotates the thread to engage the threaded hole and moves downward, driving the pressure plate 153 to move downward, so that the insulating layer 154 presses the lead wire on the contact 170 on the top of the circuit board 160. When disassembly is required, the threaded rod 151 is rotated in the opposite direction to drive the insulating layer 154 away from the circuit board 160, so that the lead wire can be quickly installed and removed from the surface of the circuit board 160, changing the welding connection method and facilitating the replacement of the lead wire.

[0032] Please refer to Figure 2 and Figure 5 As shown, adjustment chambers are provided on both sides of the inner cavity of the installation box 120, and a connecting hole is provided in the middle of the top of the adjustment chamber, the bottom of the adjustment chamber is connected to a screw rod 210 through a bearing, and pulleys are fixedly sleeved on the bottom ends of the outer sides of the two groups of screw rods 210, and the two groups of pulleys are connected through a belt 230 for transmission, one group of screw rods 210 passes through the connecting hole and extends to the top of the installation box 120, a turning handle 250 is fixedly installed on the top of the screw rod 210, a sliding block 220 is threadedly connected to the outer side of the screw rod 210, and a support block 240 is fixedly connected to one side of the sliding block 220, and the support block 240 is arranged at the bottom of the circuit board 160.

[0033] The user rotates the handle 250 to drive the screw rod 210 to rotate, and the sliding block 220 and the supporting block 240 threadedly engaged therewith move up and down, thereby adjusting the height of the circuit board 160 according to the thickness of the circuit board 160 .

[0034] When in use, the operator picks up the mounting plate 130 and aligns the L-shaped rod 370 with the slot 310, and then pushes it in. As the L-shaped rod 370 is pushed in, the trapezoidal block 330 is squeezed to move into the active chamber 320, thereby squeezing the spring 340. When the L-shaped rod 370 is fully inserted to the bottom of the inner cavity of the slot 310, the trapezoidal block 330 loses its squeezing force, and the elastic force of the spring 340 itself is used to push the trapezoidal block 330 to reset and move to the back of the L-shaped rod 370 to complete the fixed limit, so that the mounting plate 130 and the mounting box 120 are fixed and the installation is completed. When the damaged circuit board 160 needs to be replaced, the pull rod 360 is pulled to drive the trapezoidal block 330 to move into the active chamber 320, thereby releasing the limit on the L-shaped rod 370, and then the mounting plate 130 is removed, which is convenient for replacement and maintenance. The parts not involved in the device are the same as the prior art or can be implemented using the prior art.
