[0017] The following combines the drawings to elaborate in detail on the preferred embodiment of the present utility model, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present utility model.

[0018] Referring to the attached Figures 1-3 As shown, a novel photoelectric switch decoder in this embodiment includes a housing 1 and a body 2.

A plurality of countersunk holes 17 are provided on the bottom 12, and countersunk screws are provided in the countersunk holes 17.

[0019] By providing a number of countersunk holes 17 on the bottom 12, countersunk screws pass through the countersunk holes 17 to connect the countersunk screws to the production equipment, and then the body 2 is snap-fitted inside the housing 1. A complete photoelectric switch decoder is formed. This structure omits the bracket, reducing the installation cost. Since the connection of the countersunk screws has the advantages of being fast, time-saving and labor-saving, it is convenient to operate and use.

[0020] The present utility model is further configured as follows: the body 2 includes a glass cover 21, an electrical part 22, a number of clamping rods 23 and a number of conductive contacts 24. The glass cover 21 and the number of conductive contacts 24 are respectively connected to the upper end and the lower end of the electrical part 22, and the number of clamping rods 23 are connected to the side of the electrical part 22; vertical grooves 14, horizontal grooves 15 and clamping grooves 16 are provided on the side wall 11, and the vertical grooves 14, horizontal grooves 15 and clamping grooves 16 are connected end to end in sequence; the clamping rods 23 enter from the vertical grooves 14, pass through the horizontal grooves 15 until they are clamped in the clamping grooves 16; a number of elastic contacts are provided on the bottom 12, and the elastic contacts abut against the conductive contacts 24 and exert a reaction force on the conductive contacts 24.

[0021] The glass cover 21 covers the top of the housing 1. During the process of the electrical part 22 extending into the housing 1, the clamping rods 23 enter from the vertical grooves 14, pass through the horizontal grooves 15 until they enter the clamping grooves 16. At this time, a number of elastic contacts on the bottom 12 abut against the conductive contacts 24 at the lower end of the electrical part 22 and exert a reaction force on the conductive contacts 24. The electrical part 22 is pushed upward by the conductive contacts 24 until the clamping rods 23 abut against the top of the clamping grooves 16. The snap-fitting structure composed of the vertical grooves 14, horizontal grooves 15 and clamping grooves 16 is quick to install or disassemble and convenient to use. When used in combination with the installation structure composed of the countersunk holes 17 and countersunk screws, the installation efficiency is improved.

[0022] The present utility model is further configured as follows: the vertical groove 14 extends downward from the top of the side wall 11, the horizontal groove 15 is horizontally arranged, and the clamping groove 16 extends upward from one end of the horizontal groove 15. The present utility model is not limited to this, and other structures that can realize inserting the body 2 into the housing 1 are applicable to the present utility model.

[0023] The present utility model is further configured as follows: a number of accommodating grooves 18 are provided on the bottom 12, springs 6 are inserted into the accommodating grooves 18, conductive sheets 5 are connected to the tops of the springs 6, and cable wires are connected to the conductive sheets 5; the springs 6 push the conductive sheets 5 to abut against the conductive contacts 24. The elastic contacts formed by the springs 6 and the conductive sheets 5 abut against the conductive contacts 24, having the characteristic of good elasticity, which is convenient to push the electrical part 22 connected to the conductive contacts 24 and the clamping rods 23 connected to the electrical part 22 upward until the clamping rods 23 abut against the top of the clamping grooves 16.

[0024] To prevent the conductive sheet 5 from shifting, the present utility model is further configured as follows: an installation groove 3 is provided on the bottom 12, and a lining sheet 4 is clamped in the installation groove 3; the conductive sheet 5 is wrapped around a section of the lining sheet 4. The setting direction of the lining sheet 4 is the same as the rotation direction of the conductive contact 24 in the housing 1. The conductive contact 24 slides along the lining sheet 4 until it abuts against the conductive sheet 5.

[0025] The present utility model is further configured as follows: the lining sheet 4 is in an annular shape, and the lining sheet 4 at the position of the conductive sheet 5 is higher than the lining sheet 4 at the installation groove 3. The spring 6 not only lifts the conductive sheet 5 but also lifts the lining sheet 4. Due to the limitation of the installation groove 3, continuous protrusions and depressions are formed on the lining sheet 4. When the latch 23 enters the bottom end of the vertical groove 14, the conductive contact 24 just abuts against the depression. When the latch 23 enters the horizontal groove 15, the conductive contact 24 slides on the lining sheet 4.
