Description

Technical Field

[0001] The utility model relates to the technical field of switches, in particular to a dust-proof and heat-dissipating switch. Background Art

[0002] Chinese patent CN217470001U provides a switch with a dustproof and heat dissipation mechanism, which blocks the port with a dust shield to prevent dust in the air from entering the interior of the switch through the port. Through a locking component and a limit component, the dust shield can be retracted into the mounting base when the port needs to be used, without affecting the use of the port.

[0003] However, there is no positioning mechanism in the switch port, and the connector terminal is easy to loosen and fall off after being connected to the port, resulting in poor connection stability. Moreover, when the switch is running for a long time, the stability of the terminal plugged in the port is high, and the heat dissipation effect of the terminal in the port is not good. Therefore, it is necessary to design a switch with stable terminal connection and dust-proof heat dissipation. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] In view of the shortcomings of the prior art, the utility model provides a dustproof and heat-dissipating switch, which has the advantages of high connection stability and good thermal conductivity and heat dissipation effect. It solves the problem that there is no positioning mechanism in the existing switch port, the connector terminal is easy to loosen and fall off after being connected to the port, the connection stability is poor, and when the switch is running for a long time, the terminal plugged in the port is relatively stable and the heat dissipation effect of the terminal in the port is poor.

[0006] (II) Technical solution

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a dustproof and heat-dissipating switch, comprising a switch body, a connector movably connected to the right side of the switch body, a terminal fixedly arranged on the left side of the connector, a port opened on the right side of the switch body, the side surface of the terminal adapted to the inside of the port, a heat-conducting block movably plugged into the right side of the top of the switch body, a heat sink fixedly arranged on the top of the heat-conducting block, the bottom of the heat-conducting block movably connected to the top of the terminal, an insert block fixedly arranged on the bottom of the heat-conducting block, and the bottom of the insert block movably plugged into the top of the terminal.

[0008] Preferably, a square groove is provided on the right side of the top of the switch body, and springs are fixedly installed on the front and rear sides of the bottom of the heat sink, and the bottom ends of the two springs are respectively fixedly connected to the front and rear sides of the bottom wall of the square groove, and the lower surface of the heat sink is adapted to the interior of the square groove. Through the expansion and contraction of the spring, when the left terminal of the connector is plugged into the port, the bottom of the heat conductive block contacts the top of the terminal, so that the heat of the terminal is transferred to the heat conductive block, and the heat is dissipated by the heat conductive block on the heat conductive block. When the connector is pulled out, the height of the heat sink drops, so that the heat conductive block moves down to block the interface to prevent dust from entering the interface.

[0009] Preferably, a through groove is formed on the inner bottom wall of the square groove, and the through groove is connected to the inner top wall of the port. The side surface of the heat conductive block is matched with the interior of the through groove. The heat conductive block moves up and down in the through groove, which facilitates the plugging and heat dissipation of the terminal in the port and the dust prevention of the port.

[0010] Preferably, slots are provided at the top of the terminal and the inner bottom wall of the port, and the plug block is adapted to the inside of the slot. The plug block under the thermal conductive block cooperates with the slot on the terminal, so that the terminal in the port is fixed after plugging in to prevent the connector from loosening and falling off after plugging in. The plug block under the thermal conductive block cooperates with the slot on the inner bottom wall of the port, so that the thermal conductive block can easily shield the port from dust.

[0011] Compared with the prior art, the present invention provides a dust-proof and heat-dissipating switch having the following features:

[0012] Beneficial effects:

[0013] 1. The dustproof and heat-dissipating switch is provided with a heat-conducting block, a heat sink, an insert block and a spring. The heat sink is moved upward so that two springs are stretched, so that the heat-conducting block is moved upward out of the port. Then the terminal of the connector is inserted into the port. Through the restoring action of the two springs, the bottom of the heat-conducting block contacts the top of the terminal, so that the heat of the terminal is transferred to the heat-conducting block, and the heat sink on the heat-conducting block dissipates the heat. The insert block under the heat-conducting block cooperates with the slot on the terminal, so that the terminal in the port is fixed after being plugged in, and the connector is prevented from loosening and falling off after being plugged in, thereby facilitating the plugging, positioning and heat dissipation operations of the terminal in the switch port.

[0014] 2. The switch with dustproof and heat dissipation is provided with a slot, and the heat sink is moved upward, so that the two springs are stretched, so that the plug under the heat conductive block is moved upward out of the slot on the terminal, and the connector can be pulled out to the right. Through the restoring effect of the two springs, the heat conductive block is lowered into the port, so that the plug under the heat conductive block is matched with the slot on the bottom wall of the port. At this time, the heat conductive block shields the port from dust, preventing dust pollution caused by exposure when the port is not plugged in, thereby facilitating the dustproof operation of the switch port.
