1. because the existence of spacing protruding muscle, magnetic reed switch and second pencil are controllable in the downthehole position of encapsulating, can be as required lightly look for accurate both in the downthehole position of encapsulating in the operation process, improve the uniformity of product, make in each proximity switch the distance difference between magnetic reed switch and the shell outer wall at very little within range, the response scope is bigger, the inductive distance of product is unanimous, the outward appearance of product is more unanimous, pleasing to the eye.
2. The cross section is in a cross shape, four positioning insertion areas are formed, the positioning insertion areas selectively corresponding to the insertion positions of the reed switches can be selected according to customer requirements and product performance parameters, the effect of the application range of product design is improved, the variability of the overall design scheme of a client can be matched, and the success rate of the design scheme is improved.
3. The plastic body of the proximity switch is reserved with a glue-retarding opening with the height of 2 mm-3 mm and a rectangular cross section, and the proximity switch has the main functions of: one, the cooperation different electric wire external diameters provide bigger space. Secondly, when the reed switch and the electric wire are inserted into the body, the epoxy resin liquid level pre-filled in the body can rise, the square hole can delay the rising speed of the epoxy resin, and the bad phenomenon that glue overflows the body is reduced.
4. The design method is used for solving the defects of the existing approach switch plastic shell (body), the existing approach switch production process is to pour a small amount of epoxy resin into a body hole in advance, then a reed pipe assembly welded with a reed pipe and a wire harness is inserted into the hole, the epoxy resin in the hole can rise to the position of the hole opening, but the phenomena of insufficient glue or overflow of the glue exist, the glue needs to be reworked for glue supplement or the loss of poor appearance scrapping and the like in a large proportion, the design of the glue overflow groove is increased, the glue which can overflow originally is guided into the glue overflow groove through the glue guide groove, the problems are solved completely, and the purposes of reducing the loss and improving the production efficiency are effectively achieved.
