Specifically, the protective cover main body 110 is formed with an accommodating groove 111 for accommodating the mobile terminal. By putting the mobile terminal into the accommodating groove, the protective cover main body 110 can be made of materials such as silica gel, plastic, and leather. It plays a protective role and reduces the risk of damage to the shell and camera of the mobile terminal when the mobile terminal is bumped or dropped. In addition, the main body 110 of the protective case can be in any color or pattern to meet the needs of different users, and there is no specific limitation. In addition, one or more camera holes (not shown in the figure) can also be set on the protective cover main body 110. The number of camera holes is determined by the number of cameras of the mobile terminal, and the position and shape of the camera holes are related to the number of cameras of the mobile terminal.

Specifically, unlike the solution of electrically connecting the USB interface and the USB connector 141 as shown in FIG. 2 , it is also possible to use a spring-type probe (pogo pin) or conductive card slot scheme. The spring-type probe is formed by three basic parts of needle tube, spring and needle shaft after being riveted and pre-pressed by precision instruments. Wherein, the spring is located in the internal structure formed by the needle tube and the needle shaft, and can move freely. At the same time, the needle shaft can move up and down along the side wall of the needle tube. In actual application, when the needle shaft is far away from the conductive groove, the needle shaft is at the farthest end of the needle tube, the spring is not compressed or the amount of compression is very small, and at least one of the upper or lower ends of the spring is not in contact with the lower wall of the needle tube or the needle tube. When the upper wall of the shaft is in contact, the circuit of the spring-type probe is not conducted, and the electrical connection cannot be realized; when the needle shaft is close to the conductive groove and the spring is gradually compressed, when the compression of the spring is large enough, the upper and lower ends of the spring are respectively in contact with the needle tube. The lower wall is in contact with the upper wall of the needle shaft, and the spring-type probe conducts with the circuit of the conductive card slot to realize electrical connection. Preferably, the surface of the spring probe can be plated with gold, which can better improve its anti-corrosion function, mechanical performance, electrical performance and the like. Preferably, the surface of the spring can also be plated with gold, which can better improve its electrical conductivity. The needle point of the needle shaft can be a pointed needle, a grasping needle, a round needle, a knife-shaped needle, etc.

Specifically, one of the first contact end and the second contact end 241 is a conductive slot, and the other is a spring-type probe. When the first contact end of the mobile terminal is a spring-type probe, correspondingly, the circuit assembly The second contact end of 240 is a conductive card slot. The quantity and shape of the spring-type probes and the conductive slots need to match, for example, as shown in FIG. When the number is 4, correspondingly, the number of conductive card slots of the mobile terminal is also 4. When the spring-type probes are fixed in the conductive card slots, two of the spring-type probes are electrically connected to the conductive card slots. To realize the transmission of current, the other two are electrically connected to realize the transmission of data, which can realize the transmission of electric energy and transmission signal to the circuit component 240 by the mobile terminal through the spring probe. The mobile terminal is equipped with control software. When the user uses the control software to turn on the light When functioning, the mobile terminal transmits the control signal to the control board 243 through the spring probe, and the control board 243 receives the control signal and turns on or stops the output current to the light source 231 according to the control signal, so as to control the light source 231 to light up or go out. In this way, the use of the USB interface of the mobile terminal itself will not be affected by the electrical connection of the spring-type probe and the conductive card slot, which is more convenient. At the same time, the spring-type probe and the conductive card slot are applied to the mobile terminal. In electrical connection with the circuit assembly 240 as a connector, the weight and appearance of the connector can be reduced, making it more refined and beautiful.

As can be seen from the above, the present invention provides a protective cover and a method for supplementing light by using the protective cover. The protective cover includes: a main body of the protective cover, on which is formed an accommodating groove for accommodating a mobile terminal; a cover plate, a cover plate It is used to cover the surface of the screen of the mobile terminal; the light-emitting component is located on the cover plate and is used to provide supplementary light for the screen of the mobile terminal. The light-emitting component includes a plurality of light-emitting light sources and lamp beads covered on the light-emitting light source; circuit The component and the circuit component are respectively electrically connected to the mobile terminal and the light emitting component, so that the mobile terminal controls the light emitting component to turn on and off. The light-emitting component is controlled by the mobile terminal, which solves the problem in the prior art that the protective cover has a single function and cannot supplement the light of the mobile terminal, and improves user experience.
