Embodiment Construction
[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0018] see Figure 1-3 , an embodiment provided by the present invention: a ventilation and heat dissipation type electromagnetic switch protective case, including an upper cover plate 1, the bottom end of the upper cover plate 1 is fixedly connected with a second silicone pad 15, and the left side of the upper cover plate 1 There is a switch reserved slot 14, and the first slider 17 is fixedly connected to both sides of the bottom end of the upper cover plate...

The invention discloses a ventilation and heat dissipation type electromagnetic switch protection shell which comprises an upper cover plate, a second silica gel pad is fixedly connected to the bottomend of the upper cover plate, a switch reserved groove is formed in the left side of the upper cover plate, and first sliding blocks are fixedly connected to the bottom ends of the two sides, symmetrical about a center shaft, of the upper cover plate; and a second sliding groove is formed in the top end of the right side of a middle coaming, the inner wall of the second sliding groove abuts against the surface of the first sliding block, a first groove is formed in the left side of the top end of the first sliding block, a first toggle switch is inserted into the top end of the right side ofthe middle coaming, and the surface of the first toggle switch is sleeved with a first spring. By arranging the first toggle switch, the first groove, the second sliding groove and the first sliding block, the problem that maintenance and detachment are complex is solved; the surface area is increased through the cooling fins to accelerate heat dissipation; and the air circulation speed is increased through the first silica gel pad, and the problem that the heat dissipation effect is poor is solved.
Description
technical field [0001] The invention relates to the technical field of electromagnetic switch accessories, in particular to a ventilation and heat dissipation type electromagnetic switch protective case. Background technique [0002] Electromagnetic switches are widely used in various industries, and the most common ones are contactors in the industrial field. The movable iron core pushes or pulls the switch contacts to close, thereby turning on the controlled circuit. [0003] The existing electromagnetic switch protective shells are all welded by the outer shell and the bottom electrode. The protective shell is an integral structure, which is troublesome to repair and disassemble, and there is no auxiliary heat dissipation structure. The ventilation and heat dissipation effect of the protective shell is poor, and the temperature of the internal parts of the electromagnetic switch is too high. , easily damaged, so there is an urgent need for a ventilation and heat dissipati...
