Technical Field

[0001] The utility model relates to the field of circuit protection and control device equipment, in particular to a control and protection switch. Background Art

[0002] The control and protection switch adopts a modular single product structure, integrating the main functions of traditional short-circuit devices (fuses), contactors, overload (or overcurrent, phase failure) protection relays, starters, isolators and residual current modules, etc. It can connect, carry and disconnect circuits under specified abnormal conditions. The switch needs to be regularly inspected and maintained to ensure the good use of the switch;

[0003] After searching, a Chinese patent disclosed a control and protection switch (CN209447711U). This patented technology is that when the control and protection elements in the base are working, the internal and external fans are turned on to cooperate with the heat dissipation pipe to dissipate the internal heat. Due to the existence of the internal and external fans, the overall structure is not easy to disassemble, which is not conducive to the regular maintenance and repair of the control and protection switch.

[0004] Therefore, a control and protection switch is proposed to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a residual current module and a control and protection switch for controlling and protecting switches in order to solve the above problems, thereby improving the problem that the existing structure is not easy to disassemble.

[0006] The utility model achieves the above-mentioned purpose through the following technical scheme. A control and protection switch includes: a base plate, a shell is arranged on the top of the base plate; a connecting mechanism; wherein the connecting mechanism includes two clamping mechanisms arranged on the surface of the base plate and symmetrically distributed, and the clamping mechanisms are used to connect the base plate and the shell; the connecting mechanism also includes a ventilation mechanism arranged on the surface of the clamping mechanism, and the ventilation mechanism is used to ventilate the inside of the shell.

[0007] Preferably, the clamping mechanism comprises two connection blocks fixedly connected to the top of the bottom plate, one side of the connection block is fixedly connected to a slider, and one side of the slider is embedded with an adsorption block.

[0008] Preferably, two slide grooves are provided on both sides of the shell, and a clamping groove is provided on the inner wall of the slide groove. The slide groove and the clamping groove are distributed in an L shape, and a magnet is embedded and installed on the inner wall of the clamping groove.

[0009] Preferably, a through slot communicating with the card slot is provided inside the shell.

[0010] Preferably, a ventilation groove is provided on the surface of the connecting block, and a first dustproof net is fixedly connected to the inner wall of the ventilation groove.

[0012] Preferably, grooves are provided on both sides of the shell, and the inner walls of the grooves are provided with ventilation holes that are evenly distributed and communicated with the interior of the shell.

[0013] Preferably, the ventilation holes and the ventilation holes are distributed alternately.

[0014] The beneficial effects of the utility model are:

[0015] 1. The clamping mechanism can realize the rapid separation of the shell and the base. When disassembling, it is necessary to push the shell with force to overcome the suction force of the magnet on the adsorption block, thereby driving the slider to move from the inside of the card slot to the inside of the slide slot, and then the shell and the base can be quickly separated along the slide slot, so as to facilitate the staff to carry out inspection and maintenance. When installing, it is only necessary to align the slider with the slide slot and move the shell so that the slider is inserted into the card slot.

DETAILED DESCRIPTION

[0023] 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. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] When implementing: Figure 1-5 As shown, a control and protection switch comprises: a base plate 1, a shell 101 is arranged on the top of the base plate 1; a connecting mechanism 2; wherein the connecting mechanism 2 comprises two clamping mechanisms 21 arranged on the surface of the base plate 1 and symmetrically distributed, and the clamping mechanisms 21 are used to connect the base plate 1 and the shell 101; the connecting mechanism 2 also comprises a ventilation mechanism 22 arranged on the surface of the clamping mechanism 21, and the ventilation mechanism 22 is used to ventilate the inside of the shell 101.

[0025] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the clamping mechanism 21 includes two connecting blocks 2105 fixedly connected to the top of the bottom plate 1, a slider 2106 is fixedly connected to one side of the connecting block 2105, an adsorption block 2109 is embedded and installed on one side of the slider 2106, two slide grooves 2101 are provided on both sides of the shell 101, a clamping groove 2102 is provided on the inner wall of the slide groove 2101, the slide groove 2101 and the clamping groove 2102 are distributed in an L shape, a magnet 2103 is embedded and installed on the inner wall of the clamping groove 2102, a through groove 2104 connected to the clamping groove 2102 is provided inside the shell 101, a ventilation groove 2108 is provided on the surface of the connecting block 2105, and a first dustproof net 2107 is fixedly connected to the inner wall of the ventilation groove 2108;

[0026] During installation, align the slide groove 2101 on the housing 101 with the slider 2106 and insert it. After the slide groove 2101 is inserted into place, when the housing 101 is moved, the slider 2106 slides into the inside of the slot 2102, thereby preventing the slider 2106 from being separated from the housing 101. The adsorption block 2109 is an iron material component, and the magnet 2103 can generate an adsorption force on the adsorption block 2109 under the suction force of the magnet 2103, thereby strengthening the connection effect between the two and preventing the natural falling off.

[0027] After being installed in place, the through slot 2104 can be connected to the ventilation slot 2108, so that the air inside the housing 101 can be ensured through the ventilation slot 2108 and the through slot 2104, and the heat generated during use can be dissipated therethrough, without the need for a fan, thereby reducing the use cost;

[0028] When disassembling, it is only necessary to move the shell 101 with force to drive the slider 2106 to separate from the slot 2102, and then slide out through the slide slot 2101 to complete the disassembly. The operation is simple and the shell 101 can be quickly installed and disassembled, which effectively improves the efficiency of inspection and maintenance.

[0029] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the ventilation mechanism 22 includes a connecting plate 2203 fixedly connected between two connecting blocks 2105 on the same side, the surface of the connecting plate 2203 is provided with evenly distributed ventilation holes 2204, the inner wall of the ventilation hole 2204 is fixedly connected with a second dustproof net 2205, and grooves 2201 are provided on both sides of the housing 101, and the ventilation holes 2202 of the groove 2201 are staggered with the ventilation holes 2204;

[0030] After installation, the air holes 2202 and the ventilation holes 2204 are staggered and connected by the grooves 2201. The adjacent air holes 2202 and ventilation holes 2204 are connected in an approximately Z-shaped manner, making it difficult for dust to enter the interior of the shell 101 through the air holes 2202 and the ventilation holes 2204. The ventilation and heat exchange effects inside the shell 101 are enhanced through the cooperation of the air holes 2202, the grooves 2201 and the ventilation holes 2204.

[0031] When the utility model is in use, the shell 101 and the base plate 1 can be quickly installed and disassembled under the action of the snap-in mechanism 21, and the through groove 2104 can be connected with the ventilation groove 2108, so that the air inside the shell 101 can be ensured through the ventilation groove 2108 and the through groove 2104, and the heat generated during use can be dissipated therethrough, without the need for a fan, thereby reducing the cost of use. The setting of the ventilation mechanism 22 can enhance the heat exchange effect inside the shell 101, and the setting of the first dustproof net 2107 and the second dustproof net 2205 can further prevent dust from entering the interior of the shell 101.

[0032] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
