Technical Field

[0001] The utility model relates to the field of a proximity sensor, and mainly to the application of a sensing end reinforcement structure of the proximity sensor. Background Art

[0002] As technology and the times progress at an increasingly rapid pace, many manufacturing operations have gradually been improved to automated control. Since automated control relies heavily on sensors to meet the needs of different purposes, proximity switches are the most widely used type.

[0003] However, such proximity switches are subject to wear, impact, debris, acid, alkali, torque, etc. due to long-term operation in different processing environments. If the material of the proximity switch is not durable or strong enough, its replacement cycle is usually more frequent. If it is consumed for a long time, the cost of related maintenance or replacement is also considerable.

[0004] Therefore, the protection and durability of the proximity switch structures currently available on the market have not reached an ideal state, so it is necessary to further improve them. Therefore, based on the concept of continuous product improvement and innovation, the inventor has been engaged in professional practical experience in this field for many years, and has actively and attentively researched and thought about it. After countless actual designs and practices, the present invention has produced a sensing end reinforcement structure of a proximity sensor. Utility Model Content

[0005] The main purpose of the utility model is to provide a proximity sensor sensing end strengthening structure that strengthens the tightness and strength of the housing. To achieve the above purpose, the proximity sensor sensing end strengthening structure of the utility model includes: a housing, a sensing module component is disposed inside the housing, a sensing coil is disposed at the front end of the sensing module component, and a transmission wire is electrically connected to the rear end of the sensing module component.

[0006] The housing is bonded to a stainless steel sheet at the front end by an adhesive, so that one side edge of the sensing module assembly can be closely attached to an inner wall of the housing to be fixed, further enhancing the tightness and strength of the housing.

[0007] Another object of the present invention is to make the shell material of copper or stainless steel.

[0008] The structure of the utility model mainly uses a relatively hard metal to form the shell. In addition, a stainless steel sheet is also used at the front end of the shell with a special adhesive, so that the front end of the shell and the stainless steel sheet are firmly and tightly fitted, and the overall strength can be enhanced to effectively avoid damage during work detection.

[0024] The following is a detailed description of the structure and function of the present invention by using a preferred embodiment with accompanying drawings to increase the understanding of the present invention; the present invention is a proximity sensor sensing end reinforcement structure, and the proximity sensor is generally divided into embedded type and exposed type, please refer to Figure 1 to Figure 6 The main structure is composed of: a shell 10, in which a sensing component 20 is encapsulated and arranged. A sensing coil 21 is arranged at the front end of the sensing module 20, and a transmission wire 22 is electrically connected to the rear end of the sensing module 20. The sensing module 20 is usually also electrically connected to some parts such as a circuit board, but this part is a common design in this field, so it is not elaborated.

[0025] The shell 10 has an adhesive 40 evenly applied to the connection between an inner wall 11 of the shell 10 and a stainless steel sheet 30 at the front end, so that a side edge 201 of the sensing module 20 can be closely attached to the inner wall 11 of the shell 10 and fixed, further enhancing the tightness and strength of the shell 10.

[0026] In summary, the proximity sensor of the present invention uses a stainless steel or copper shell 10, and the inner wall 11 of the shell 10 can effectively protect the sensing module 20 therein, and the stainless steel sheet 30 can be further sealed with the shell 10 through the adhesive 40, so it can perform detection work under wear, impact, spark, acid, alkali, and torque environments. The stainless steel sheet 30 can also effectively ensure that the sensing coil 21 can have a certain degree of resistance even if it is affected by the external force environment, so the durability of the proximity sensor can be effectively improved.
