[0012] Preferably, a connecting copper ring matching with the pin is arranged in the socket, and wiring heads are fixed on both the pin and the connecting copper ring.
[0013] Advantages of the utility model:
[0014] (1) The utility model provides an embodiment. By contacting the moving contact with the static contact, the moving contact and the static contact can be conducted, so that the indicator light can be powered on and can light up. By lighting up, it can be judged whether the pin is firmly connected to the socket. The insulating surface can prevent the pin from being conducted with the moving contact. The socket is provided with an indicator light and a battery. After the pin presses the insulating surface, the moving contact contacts the static contact, so that the battery is connected to the indicator light.
[0015] (2) In an embodiment of the utility model, the first conductive plate is an arc-shaped plate, which is convenient for subsequent deformation after being in close contact with the static contact. The length of the pin is such that the needle tip can push the moving contact into place after being inserted tightly. Pushing the moving contact into place means that the moving contact is in close contact with the static contact, causing the first conductive plate to deform.
[0016] (3) In an embodiment of the utility model, the material of the first conductive plate can be a metal with anti-fatigue ability, which can adapt to long-term deformation and avoid fracture.
[0017] The utility model can judge whether the pin is firmly connected to the socket through the indicator light. Description of the drawings

[0021] The following further describes the utility model with reference to the drawings.
[0022] Such as Figures 1 to 3, the present utility model provides an embodiment: a device capable of judging the firm connection between a pin and a socket. The socket 1 is provided with a sensing component inside, and through the sensing component, it is convenient to judge whether the pin 4 and the socket 1 are firmly connected subsequently; the sensing component includes a contact group, and the contact group includes a moving contact 21 connected inside the socket 1 via a spring 23, and a static contact 22 fixed inside the socket 1 and cooperating with the moving contact 21. By the contact of the moving contact 21 and the static contact 22, the moving contact 21 and the static contact 22 can be conducted, so that the indicator light 3 can be powered on and can light up. By the lighting of the indicator light, it can be judged that the pin 4 and the socket 1 are firmly connected; the moving contact 21 is provided with an insulating surface 24 for the pin 4 to contact, and through the insulating surface 24, it can be avoided that the pin 4 is conducted with the moving contact 21; the socket 1 is provided with an indicator light 3 and a battery. After the pin 4 presses the insulating surface 24, the moving contact 21 contacts the static contact 22, and the battery is connected to the indicator light 3.
[0023] After the pin 4 is inserted into the jack 101 of the socket 1, it presses the insulating surface 24 and drives the moving contact 21 to move. At this time, the spring 23 is compressed. When the pin 4 is pulled out, the spring 23 drives the moving contact 21 to move due to the reset effect, so as to disconnect the contact with the static contact 22.
[0024] In an embodiment of the present utility model, first conductive plates 26 are fixed on both sides of the spring 23 inside the socket 1, and the front convex part of the first conductive plate 26 is the static contact 22; a second conductive plate 25 is connected to the spring 23, and the convex parts at both ends of the second conductive plate 25 are the moving contacts 21; an insulating block 27 is fixed on the front side of the second conductive plate 25, and the insulating surface 24 is provided on the insulating block 27.
[0025] In an embodiment of the present utility model, the first conductive plate 26 is an arc-shaped plate, which is convenient for deforming after closely contacting the moving contact 21. The length of the pin 4 is such that the needle tip can push the moving contact 21 into place after being inserted tightly. Pushing the moving contact 21 into place means that the moving contact 21 closely contacts the static contact 22 to cause the first conductive plate 26 to deform.
[0026] In an embodiment of the present utility model, the material of the first conductive plate 26 can be a metal with strong anti-fatigue ability and good electrical conductivity, which can adapt to long-term deformation and avoid breakage.
[0027] In an embodiment of the present utility model, the insulating surface 24 is a groove matching the pin 4, which can better allow the pin 4 to press the insulating surface 24.
[0028] In an embodiment of the present utility model, the socket 1 is provided with a battery compartment 5 for placing a battery.
[0029] In an embodiment of the present utility model, the pin 4 is arranged on the plug 7.
[0030] In an embodiment of the present utility model, a connection copper ring 8 that cooperates with the pin 4 is provided inside the socket 1, and terminal heads 9 are fixed on both the pin 4 and the connection copper ring 8 for connecting external cable wiring.
[0031] In an embodiment of the present utility model, the number of the pins 4 is eight, and the number of the contact groups is eight. The eight contact groups and the battery as well as the indicator light 3 form a series circuit. That is, after all the stationary contacts 22 and the moving contacts 21 in the eight contact groups are in contact, the series circuit will form a path and the indicator light 3 will light up. If the indicator light 3 does not light up, it can be judged that the pin 4 is not firmly inserted into the socket 1.
[0032] In an embodiment of the present utility model, a resistor 10 is further connected in the series circuit to enable the indicator light 3 to work properly without being burned out.
[0033] In an embodiment of the present utility model, a power supply light 11 electrically connected to the battery is provided on the socket 1 for monitoring whether the battery has power. A parallel circuit is connected to the series circuit of the contact groups and the indicator light 3, and the power supply light 11 is connected to the parallel circuit, which can ensure that the power supply light 11 is always on after being powered on.
[0034] The above are only the preferred embodiments of the present utility model, and should not be construed as limitations to this application. Any equivalent changes and modifications made according to the scope of the patent application of the present utility model shall fall within the scope covered by the present utility model.
