Description

Technical Field

[0001] This utility model belongs to the field of BMS board technology, and in particular relates to a BMS board anti-loosening wire clip device. Background Technology

[0002] BMS is a magnetic semiconductor material with a unique electronic band structure: the valence band top and conduction band bottom are 100% spin-polarized, and their spin polarization directions are opposite. It is often used in the manufacture of circuit boards.

[0003] The utility model with announcement number CN222073463U discloses a circuit board with an improved wire structure, including a circuit board body. The circuit board body includes a first substrate, an insulating film, a second substrate, a moisture-proof coating, and a wear-resistant coating. The insulating film is fixedly connected to the bottom end of the first substrate, and the second substrate is fixedly connected to the bottom end of the insulating film. The top end of the first substrate is coated with a moisture-proof coating, and the top end of the moisture-proof coating is coated with a wear-resistant coating. Thermal paste layers are fixedly connected to both sides of the bottom end of the circuit board body, and heat dissipation fins are fixedly connected to the bottom end of the thermal paste layers. A wire management mechanism is connected to one side of the top end of the circuit board body.

[0004] The aforementioned application document uses a double-layer substrate design to allow for more complex wiring, and the surface moisture-proof and wear-resistant coatings improve the protection of the wires. The circuit board also has good heat dissipation performance. However, its effect on limiting the wires is poor, and the wires are prone to loosening and falling off during use. Therefore, it needs to be improved. Utility Model Content

[0005] The purpose of this invention is to provide a BMS board anti-loosening wire clip device, which solves the existing problems.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a BMS board anti-loosening wire clip device, comprising a base plate. The top of the base plate has positioning holes, through holes, heat dissipation holes, and heat dissipation grooves. The bottom of the base plate has an elastic strip and a thermal paste layer. Heat dissipation fins are fixedly connected to the bottom of the thermal paste layer. The top of the base plate has contacts and an anti-loosening clip mechanism. The anti-loosening clip mechanism includes a clip base fixedly connected to the top of the base plate. A sliding rod is slidably connected through the top of the clip base. A circular block is fixedly connected to the top of the sliding rod. The surface of the sliding rod... A return spring is fitted onto the slide rod. A pressure plate is fixedly connected to the bottom of the slide rod. A groove is provided on the side of the pressure plate. A compression spring is installed inside the groove. A locking block is elastically connected inside the groove through the compression spring. A locking groove is provided on the inner side wall of the locking seat. An air chamber is fixedly connected inside the locking seat. An air bag is provided at one end of the air chamber. A piston rod is slidably connected to the piston at the other end of the air chamber. A push plate is fixedly connected to the end of the piston rod away from the air chamber. An anti-bounce mechanism is provided on the top of the pressure plate.

[0007] Furthermore, the number of card holders corresponds to the number of contacts, and the card holders are located directly above the contacts. During installation, the wires are connected to the contacts.

[0008] Furthermore, the two ends of the return spring abut against the bottom of the circular block and the top of the card holder, respectively, and the return spring is compressed when the circular block moves downward.

[0009] Furthermore, the end of the card block away from the compression spring abuts against the inner wall of the card seat, and the compression spring is initially in a compressed state.

[0010] Furthermore, the longitudinal length of the slot is equal to that of the groove, and the front-to-back width of the slot is greater than that of the groove, so that the front-to-back width of the push plate prevents it from entering the groove.

[0011] Furthermore, the anti-kick mechanism includes a connecting rod and a rubber block. One end of the connecting rod is fixedly connected to the top of the pressure plate, and the other end of the connecting rod has an opening groove. A telescopic spring is installed inside the opening groove, and an arc-shaped block is elastically connected inside the opening groove through the telescopic spring. The rubber block is fixedly connected to the inner side wall of the card seat.

[0012] Furthermore, the end of the arc-shaped block away from the telescopic spring is close to the rubber block, and the rubber block is generally semi-cylindrical. When the arc-shaped block moves with the connecting rod, the end away from the telescopic spring will contact the rubber block.

[0013] This utility model has the following beneficial effects: 1. This utility model has an anti-loosening buckle mechanism, so that when it is necessary to install the wire, the wire can be inserted into the card holder, and then the pressing block drives the sliding rod and pressure plate to move downward. The downward movement of the pressure plate will press the wire to make it in close contact with the contact point, and the card block will automatically lock into the card slot to fix the position of the pressure plate, thereby preventing the wire and the contact point from loosening and falling off.

[0014] 2. This utility model has an anti-bounce mechanism, which achieves the effect of pressing the airbag to push the push plate to push the block away from the slot, and the return spring rebounding to drive the round block and slide rod to move upward and restore. It also has a damping effect through the cooperation of components such as connecting rod, arc block, and rubber block to prevent the slide rod and round block from bouncing up and down.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-6 This utility model relates to a BMS board anti-loosening wire clip device, comprising a base plate 1. The top of the base plate 1 has a positioning hole 2, a through hole 3, a heat dissipation hole 4, and a heat dissipation groove 5. The bottom of the base plate 1 has an elastic strip 6 and a thermal paste layer 7. Heat dissipation fins 8 are fixedly connected to the bottom of the thermal paste layer 7. The top of the base plate 1 has a contact point 9 and an anti-loosening clip mechanism 10. The anti-loosening clip mechanism 10 includes a clip seat 101, which is fixedly connected to the top of the base plate 1. A slide rod 102 is slidably connected through the top of the clip seat 101. A round block 103 is fixedly connected to the top of the slide rod 102. A return spring 1013 is sleeved on the surface of the slide rod 102. A pressure plate 104 is fixedly connected to the bottom of 102. A groove 105 is provided on the side of the pressure plate 104. A compression spring 106 is provided inside the groove 105. A locking block 107 is elastically connected inside the groove 105 through the compression spring 106. A locking groove 108 is provided on the inner side wall of the locking seat 101. An air chamber 109 is fixedly connected inside the locking seat 101. An air bag 1010 is provided at one end of the air chamber 109. A piston rod 1011 is slidably connected to the piston inside the other end of the air chamber 109. A push plate 1012 is fixedly connected to the end of the piston rod 1011 away from the air chamber 109. An anti-bounce mechanism 11 is provided on the top of the pressure plate 104.

[0021] As shown in the figure, the number of card holders 101 corresponds to the number of contacts 9, and the card holders 101 are located directly above the contacts 9. During installation, the wires are connected to the contacts 9.

[0022] As shown in the figure, the two ends of the return spring 1013 abut against the bottom of the circular block 103 and the top of the card holder 101, respectively. When the circular block 103 moves downward, the return spring 1013 will be compressed.

[0023] As shown in the figure, the end of the card block 107 away from the compression spring 106 abuts against the inner wall of the card seat 101, and the compression spring 106 is initially in a compressed state.

[0024] As shown in the figure, the longitudinal length of the slot 108 is equal to that of the groove 105, and the front-to-back width of the slot 108 is greater than that of the groove 105. The front-to-back width of the push plate 1012 prevents it from entering the groove 105.

[0025] As shown in the figure, the anti-bullet movement mechanism 11 includes a connecting rod 111 and a rubber block 115. One end of the connecting rod 111 is fixedly connected to the top of the pressure plate 104, and the other end of the connecting rod 111 has an opening groove 112. A telescopic spring 113 is installed inside the opening groove 112, and an arc-shaped block 114 is elastically connected inside the opening groove 112 through the telescopic spring 113. The rubber block 115 is fixedly connected to the inner side wall of the card seat 101.

[0026] As shown in the figure, the end of the arc-shaped block 114 away from the telescopic spring 113 is close to the rubber block 115. The rubber block 115 is semi-cylindrical in shape. When the arc-shaped block 114 moves with the connecting rod 111, the end away from the telescopic spring 113 will contact the rubber block 115.

[0027] A specific application of this embodiment is as follows: When it is necessary to connect the wire to the contact 9 on the substrate 1, the wire is inserted into the card holder 101, the pressing block 103 drives the slide rod 102 to move downward, the slide rod 102 moves downward and drives the pressure plate 104 to move downward, the pressure plate 104 presses the wire, and when the pressure plate 104 moves downward and the groove 105 coincides with the card slot 108, the compression spring 106 rebounds and drives the card block 107 to engage with the card slot 108. Inside 08, the position of the pressure plate 104 is fixed to prevent the wire and contact 9 from loosening and falling off. When it is necessary to remove the wire, press the airbags 1010 on both sides. The airbags 1010 are compressed, and the air pressure inside them enters the pressure chamber 109, pushing the piston rod 1011 to move out of the pressure chamber 109. The movement of the piston rod 1011 to the outside of the pressure chamber 109 will drive the push plate 1012 to move. The movement of the push plate 1012 will push the locking block 107 back into the groove 105. At this time, the return spring 1013 drives the slide rod 102, pressure plate 104 and round block 103 to bounce upwards and return to their original positions, releasing the airbag 1010. The airbag 1010 rebounds, and the air pressure returns from the air pressure chamber 109 to the airbag 1010. The piston rod 1011 drives the push plate 1012 to move in the opposite direction and return to its original position. As the pressure plate 104 moves downwards, it drives the connecting rod 111 to move downwards. As the connecting rod 111 moves downwards, it causes the arc surface of the arc block 114 to contact the rubber block 115. At this time, the arc surface of the arc block 114 is squeezed and will retract into the opening groove 112, so that it will not squeeze the rubber block 115 too much and generate a large resistance. Then the extension spring 113 drives the return to its original position. As the slide rod 102, pressure plate 104 and round block 103 bounce upwards and return to their original positions, the straight surface of the arc block 114 will squeeze the rubber block 115 and generate a large resistance, thereby preventing the slide rod 102 and round block 103 from bouncing up and down.
