[0002] A photoresistor is a resistor whose resistance value changes with the change of light intensity. The photoresistor in the prior art is composed of a photoresistor body and a plastic casing. A circular groove is arranged in the center of the side of the plastic casing. The photoresistor The main body is set in the groove, and then it is frozen in the groove with epoxy resin glue. This kind of photoresistor that is only solidified by epoxy resin glue has certain disadvantages: on the one hand, in the process of assembling the photoresistor, often When the groove of the plastic casing is filled with epoxy resin, it is easy to overflow the epoxy resin, which will affect the effect of resisting ultraviolet rays of the photosensitive resistor and reduce its sensitivity; The process is cumbersome and the scrap rate is high

Embodiment Construction
[0011] Such as figure 1 As shown in -2, a photoresistor with simple installation described in the embodiment of the present invention includes a resistor body 3 and a plastic casing 1, a circular groove 2 is provided at the center of the side of the plastic casing 1, and the groove 2 There are two shoulders 21 on the outer circumference, and the shoulders 21 and the groove 2 are integrated. The photoresistor body 3 is connected to the plastic casing 1 through the first contact surface 31 and the second contact surface 22 on the shoulder 21. socket.
[0012] The shape of the second contact surface 22 on the shoulder 21 is variable, and may be circular, rectangular, oval, etc., and the number of the shoulders 21 may be two or more.

The invention relates to a photoresistor with simple installation. The photoresistor comprises a resistor body and a plastic jacket. A circular groove is arranged in a center of a lateral surface of the plastic jacket. An outer lateral circumference of the groove is provided with two convex shoulders which are integrated with the groove. The photoresistor body is sleeved with the plastic jacket by a first contact surface of the resistor body and a second contact surface on the convex shoulders. The photoresistor with simple installation disclosed by the invention has the beneficial effects that: the outer lateral circumference of the groove of the plastic jacket is provided with the convex shoulders that enable the photoresistor to be sleeved with the plastic jacket with no need to take epoxy resin as a solidification glue, so as to enable that the photoresistor works more steadily; and is assembled more simply and practically and the cost of the photoresistor is reduced.
