Description

Proximity sensor terminal bending structure

The present invention is a proximity sensor terminal bending structure, which is designed such that the proximity sensor and the back end cladding layer are designed to be perpendicular to each other, and the two are closely combined and fixed, and the wire is disposed inside and the structure can prevent damage. Can be replaced by fiber optic material, the overall structure is used in a narrower working environment.

With the advancement of technology and the times, manufacturing and production are gradually relying on automated machinery or automated production lines. The most important sensing components can provide functions such as inspection, good product screening, mobile positioning, etc., and then meet the needs of different purposes. There are also a variety of different types to choose from. The common types are generally divided into photoelectric type, which uses signal beam penetration, concealing and reflection signal feedback. Inductive and capacitive systems transmit signals through the transmission line to the mechanical control. The terminal or signal receiving end, so the durability of the transmission line terminal and its protection structure are more important; however, in the prior art terminal, in the case of a narrower working environment, although the bending angle can be matched to the installation, Close to the internal structure of the sensor and the transmission line, please refer to Figure 5, because the design of the transmission wire has its minimum bending radius. After long-term vertical bending angle, the transmission line may be poorly connected or the internal circuit board may be short-circuited. The problem is that the number of replacements is increased and the cost is increased. In order to effectively improve the use period, further improvement is needed.

In view of the above various situations and problems, the creators have accumulated years of experience in the development of related industries and have devoted themselves to the lack of the above-mentioned conventional structures, creating a proximity sensor terminal bend that is more in line with the needs of modern users. Folded structure.

The invention is a bending structure of a proximity sensor terminal, and a main circuit board is connected inside the casing to connect the front end circuit board, and an iron powder core is arranged in front of the front end circuit board, and the iron powder core is covered with a rubber head, and the rear end a recess and one or more recessed grooves are provided, and the recessed groove is communicated with the recessed groove and is provided with a transparent or translucent material cover, and a rear cover is provided with a cladding layer; the transmission line is connected to the rear of the main circuit board, There are more than one metal core wire group inside the transmission line; the front end of the casing joint is embedded at the rear of the casing, the cladding layer is covered under the rear end of the casing, a part of the transmission line, and more than one slit is provided.

After the main circuit board of the creation is connected with the transmission line, the plastic material of the cladding is used to heat and press the injection molding machine, and the casing and the transmission line are positioned by the mold, so that the plastic material coated with the liquid is filled in the casing. The connection position with the housing joint allows the housing to be tightly coupled with the housing joint; and the rear end is formed at a vertical angle, the internal structure retaining a portion of the space for the metal core group to be placed therein, in accordance with the strength of the external structure, The internal wire can maintain a good angle and can be replaced with a fiber material to avoid damage caused by excessive bending or to cause poor connection of the internal circuit board, thereby protecting the overall structure and reducing the overall volume, making the configuration more flexible and convenient.

The outer side of the iron powder core 161 is covered with a rubber head 12, and a groove 132 and one or more slots are provided at the rear end. 133, the recess 133 is communicated with the recess 132 and is provided with a transparent or translucent material cover 15 , and a lower end of the rear end is provided with a cladding layer 13; the transmission line 14 is connected to the rear of the main circuit board 16 , and the transmission line 14 is internally One or more metal core sets 141 are provided; the front end of the shell joint 111 is embedded behind the casing 11, and the cladding layer 13 is covered under the rear end of the casing 11, a part of the transmission line 14, and more than one is provided. The groove 131 is cut.

Referring to the drawings in the first to third A drawings, the present invention is connected to the sensor terminal bending structure, and the transmission line 14 connected under the rear end of the housing 11 is connected above the metal core group 141 disposed inside. At the portion of the main circuit board 16, the metal core group 141 has a curved shape, and when the cladding layer 13 is formed by injection molding (referring to a processing method such as heating, pressurization, mold matching, etc.), a space is provided inside to transmit the transmission line 14. Tightly configured, and the bending angle of the transmission line 14 is the bending radius of the wire, and the transmission line 14 can also be replaced with a fiber material to make the near The sensor 1 can have the characteristics of optical fiber transmission. If external force is applied to the outside of the cladding layer 13, the cladding layer 13 can protect the internal transmission line 14 from being connected to the main circuit board 16 without causing damage due to external force. A groove 132 and a recess 133 are further disposed behind the cover layer 13. The central recess 132 is provided with a light-emitting diode 151, and the periphery is also provided with a plurality of recesses 133, the recess 132 and the recessed groove. 133 is in communication, and the number of the recessed grooves 133 can also be changed before production, so that the light source generated by the light-emitting diode 151 can be used to determine whether the function is functioning normally; for example, as shown in the fourth to fourth A drawings As shown in the figure, the production machine environment and its proximity sensor 1 application shown in the figure are an embodiment, a production machine 2, when the object 23 (refers to the finished product, semi-finished products, parts, components, etc.) After the workstation is manufactured, it is transported by the transport rail 24, and the proximity sensor 1 is mounted on the fixing member 241 above the transport rail 24. The upper and lower ends of the fixing member 241 have a structure 242 of the production machine 2, and when the object 23 moves To the proximity sensor 1, after the sensing is performed, the information is transmitted by using the transmission line 14. The signal processing terminal 22 to the control terminal 21 performs planning and management related information. If the conventional proximity sensor 3 in the prior art FIG. 5 is installed here, the overall length is greater than the distance unit A, and if it is forcibly installed, it is used. The transmission line 31 must be bent. After long-term use, the conventional transmission line 31 is liable to be damaged. For example, the vertical angle design of the cladding layer 13 can be installed in the narrow space of the distance A, and It is necessary to bend the transmission line 14, which is superior in durability; in summary, it has been specifically reduced and structurally protected; however, as described above, only the proximity sensor terminal of the present invention is bent.
