Description

Technical Field

[0001] The utility model relates to the technical field of wire fixing structures, in particular to a wire fixing structure for a hardware circuit. Background Technique

[0002] In a hardware circuit, a wire fixing structure usually refers to a component used to fix and connect electronic components, circuit boards or wires. The main objectives of such a structural design are to ensure the reliability of electrical connections and provide mechanical stability at the same time.

[0003] In the prior art, a pin-type chip is fused with the pads on a circuit board through its pins. However, when the pin-type chip needs to be replaced due to damage, it is not easy to connect and disconnect the circuit for the chip soldered on the circuit board. Therefore, a wire fixing structure for a hardware circuit is proposed to solve the above problems. Content of the Utility Model

[0004] (1) Technical Problems to be Solved

[0005] In view of the deficiencies of the prior art, the utility model provides a wire fixing structure for a hardware circuit, which has the advantages of being convenient for connecting and disconnecting the circuits of a circuit board and a pin-type chip, etc., and solves the problem that in the prior art, a pin-type chip is fused with the pads on a circuit board through its pins, but when the pin-type chip needs to be replaced due to damage, it is not easy to connect and disconnect the circuit for the chip soldered on the circuit board.

[0006] (2) Technical Solutions

[0007] The technical solution for the utility model to solve the above technical problems is as follows: A wire fixing structure for a hardware circuit includes a printed circuit board, a pin-type chip and a rectangular shell. The pin-type chip includes first pins. Second pins which are symmetrically distributed left and right and extend to both sides thereof are embedded in the rectangular shell. One ends of the second pins far away from the rectangular shell are soldered to the printed circuit board and electrically connected. A placement block which extends above the rectangular shell and is adapted to the pin-type chip is slidably connected inside the rectangular shell. Insertion grooves which are longitudinally equidistantly distributed and are adapted to the first pins are formed on both the left and right sides of the placement block. Limiting grooves which are symmetrically distributed front and back are formed on the top of the pin-type chip. L-shaped pressing plates which are symmetrically distributed front and back and are adapted to the limiting grooves are spring-hinged on the top of the rectangular shell. Elasticity components which are longitudinally equidistantly distributed and extend into the placement block are arranged on the bottom wall of the inner cavity of the rectangular shell. Contact components which are located inside the rectangular shell and are adapted to both the insertion grooves and the first pins are arranged on the opposite sides of the second pins.

[0008] The beneficial effects of the utility model are as follows:

[0009] The fixed-line structure used in this hardware circuit places the pin-type chip on the top of the placement block, and inserts the first pins of the pin-type chip into the insertion slots on the left and right sides of the placement block. Then, press down the pin-type chip so that it moves downward together with the placement block, thereby causing the elastic component to undergo elastic deformation, making the L-shaped pressing plate rotate towards its opposite side. Then, release the pressure on the pin-type chip, and the elastic component restores its elastic deformation. Its elastic force drives the pin-type chip and the placement block to move upward until the L-shaped pressing plate snaps into the limiting slot on the top of the pin-type chip, thus limiting the pin-type chip. During the above process, when pressing down the pin-type chip, the first pins contact the contact component until the pin-type chip is completely limited. The contact component always contacts the first pins, that is, the circuit connection between the pin-type chip and the printed circuit board is completed. When it is necessary to disconnect the circuit connection between the pin-type chip and the printed circuit board, make the L-shaped pressing plate rotate towards its opposite side, and then separate the L-shaped pressing plate from the limiting slot on the top of the pin-type chip, thereby releasing the limitation on the pin-type chip, making the elastic component restore its elastic deformation, making the placement block drive the pin-type chip to move upward, and at the same time, the contact component and the first pins are separated, and the pin-type chip can be removed from the top of the placement block. It has the advantages of facilitating the connection and disconnection of the circuit between the printed circuit board and the pin-type chip.

[0010] On the basis of the above technical solution, the present utility model can be further improved as follows.

[0011] Further, the elastic component includes a top rod and a first spring. The bottom wall of the inner cavity of the rectangular shell is fixedly connected with top rods arranged longitudinally at equal distances and extending into the placement block, and first springs located in the placement block are arranged on the tops of the top rods.

[0012] The beneficial effect of adopting the above further solution is that the pin-type chip is placed on the top of the placement block, and the first pins of the pin-type chip are inserted into the insertion slots on the left and right sides of the placement block. Then, press down the pin-type chip so that it moves downward together with the placement block, thereby causing the first spring to undergo elastic deformation, making the L-shaped pressing plate rotate towards its opposite side. Then, release the pressure on the pin-type chip, and the first spring restores its elastic deformation. Its elastic force drives the pin-type chip and the placement block to move upward until the L-shaped pressing plate snaps into the limiting slot on the top of the pin-type chip, thus limiting the pin-type chip.

[0013] Further, the contact component includes a copper connection seat, a second spring, a movable seat, and a spherical contact. Copper connection seats located inside the rectangular shell are fixedly connected to the opposite sides of the second pins. Second springs are fixedly connected to the opposite sides of the copper connection seats. Movable seats slidably connected to the rectangular shell are fixedly connected to the opposite sides of the second springs. Spherical contacts extending into the rectangular shell and adapted to the insertion slots and the first pins are movably connected to the opposite sides of the movable seats.

[0014] The beneficial effect of adopting the above further solution is that the pin-type chip is placed on the top of the placement block, and the first pins of the pin-type chip are inserted into the insertion slots on the left and right sides of the placement block. Then, the pin-type chip is pressed downward so that it and the placement block move downward simultaneously. During this process, the first pins move downward, and thus the first pins come into contact with the spherical contacts. As the first pins move downward, they drive the spherical contacts to move within the movable seat until the pin-type chip is limited. Due to the elastic force of the second spring, the spherical contacts always contact the first pins, enabling the electrical connection between the pin-type chip and the printed circuit board.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] In the embodiment, by Figures 1-4Provided is a wire fixing structure for a hardware circuit. The utility model includes a printed circuit board 1, a pin-type chip 2 and a rectangular shell 3. The pin-type chip 2 includes a first pin 4. Inside the rectangular shell 3, second pins 5 which are symmetrically distributed left and right and extend to both sides thereof are embedded. One end of each second pin 5 far from the rectangular shell 3 is welded to the printed circuit board 1 and electrically connected. A placing block 6 which extends above the rectangular shell 3 and is adapted to the pin-type chip 2 is slidably connected inside the rectangular shell 3. Insertion grooves 7 which are longitudinally equidistantly distributed and adapted to the first pins 4 are formed on both the left and right sides of the placing block 6. Limiting grooves 8 which are symmetrically distributed front and back are formed at the top of the pin-type chip 2. L-shaped pressing plates 9 which are symmetrically distributed front and back and adapted to the limiting grooves 8 are spring-hinged to the top of the rectangular shell 3. Elastic force components 10 which are longitudinally equidistantly distributed and extend into the placing block 6 are arranged on the inner cavity bottom wall of the rectangular shell 3. Contact components 11 which are located inside the rectangular shell 3 and are adapted to both the insertion grooves 7 and the first pins 4 are arranged on the opposite sides of the second pins 5;

[0022] The elastic force components 10 include ejector rods 101 and first springs 102. Ejector rods 101 which are longitudinally equidistantly distributed and extend into the placing block 6 are fixedly connected to the inner cavity bottom wall of the rectangular shell 3. First springs 102 which are located inside the placing block 6 are arranged at the tops of the ejector rods 101;

[0023] Place the pin-type chip 2 on the top of the placing block 6, and insert the first pins 4 of the pin-type chip 2 into the insertion grooves 7 on both the left and right sides of the placing block 6. Then press the pin-type chip 2 downward so that it and the placing block 6 move downward simultaneously, thereby causing the first springs 102 to undergo elastic deformation, causing the L-shaped pressing plates 9 to rotate toward their opposite sides. Then release the pressing of the pin-type chip 2, and the first springs 102 recover elastic deformation. Their elastic force drives the pin-type chip 2 and the placing block 6 to move upward until the L-shaped pressing plates 9 are snapped into the limiting grooves 8 at the top of the pin-type chip 2, and then the pin-type chip 2 can be limited;

[0024] The contact components 11 include copper connecting seats 111, second springs 112, movable seats 113 and spherical contacts 114. Copper connecting seats 111 which are located inside the rectangular shell 3 are fixedly connected to the opposite sides of the second pins 5. Second springs 112 are fixedly connected to the opposite sides of the copper connecting seats 111. Movable seats 113 which are slidably connected to the rectangular shell 3 are fixedly connected to the opposite sides of the second springs 112. Spherical contacts 114 which extend into the rectangular shell 3 and are adapted to both the insertion grooves 7 and the first pins 4 are movably connected to the opposite sides of the movable seats 113;

[0025] Place the pin-type chip 2 on top of the bearing block 6, and insert all the first pins 4 of the pin-type chip 2 into the insertion slots 7 on the left and right sides of the bearing block 6. Then, press down on the pin-type chip 2 so that it and the bearing block 6 move downward simultaneously. During this process, the first pins 4 move downward, and thus the first pins 4 come into contact with the spherical contacts 114. As the first pins 4 move downward, they drive the spherical contacts 114 to move within the movable seat 113 until the pin-type chip 2 is limited. Due to the elastic force of the second spring 112, the spherical contacts 114 always remain in contact with the first pins 4, enabling the electrical connection between the pin-type chip 2 and the printed circuit board 1.

[0026] Working principle:

[0027] Step 1: Place the pin-type chip 2 on top of the bearing block 6, and insert all the first pins 4 of the pin-type chip 2 into the insertion slots 7 on the left and right sides of the bearing block 6. Then, press down on the pin-type chip 2 so that it and the bearing block 6 move downward simultaneously. During this process, the first pins 4 move downward, and thus the first pins 4 come into contact with the spherical contacts 114. As the first pins 4 move downward, they drive the spherical contacts 114 to move within the movable seat 113, and at the same time, the first spring 102 undergoes elastic deformation.

[0028] Step 2: Rotate the L-shaped pressing plate 9 towards its opposite side, and then release the pressure on the pin-type chip 2. The first spring 102 resumes its elastic deformation, and its elastic force drives the pin-type chip 2 and the bearing block 6 to move upward until the L-shaped pressing plate 9 is caught in the limiting slot 8 at the top of the pin-type chip 2, thereby limiting the pin-type chip 2. Due to the elastic force of the second spring 112, the spherical contacts 114 always remain in contact with the first pins 4, enabling the electrical connection between the pin-type chip 2 and the printed circuit board 1, that is, the electrical connection between the pin-type chip 2 and the printed circuit board 1 is completed.

[0029] Step 3: When it is necessary to disconnect the electrical connection between the pin-type chip 2 and the printed circuit board 1, rotate the L-shaped pressing plate 9 towards its opposite side, and then separate the L-shaped pressing plate 9 from the limiting slot 8 at the top of the pin-type chip 2, thereby releasing the limitation on the pin-type chip 2, enabling the first spring 102 to resume its elastic deformation, causing the bearing block 6 to drive the pin-type chip 2 to move upward, and at the same time, both the spherical contacts 114 and the first pins 4 are separated, and then the pin-type chip 2 can be removed from the top of the bearing block 6.
