In some examples, the through holes are provided only in the thickness direction of the insulating plate 30, and the shape of the through holes may be any shape without being particularly limited. The through holes are provided at positions where the insulating plate 30 is located close to the nearest position or relatively close to the circuit board 10 to be grounded. In other examples, only the notch 302 is provided, and the notch is provided along the edge of the insulating plate 30, specifically at a position where the insulating plate 30 is close to the nearest edge of the circuit board 10 to be grounded. In still other examples, vias and notches 302 may be present at the same time, and separate grounding may be required at multiple locations on circuit board 10, and multiple electrical connectors 40 may be used, optionally positioned along vias or notches 302 depending on the particular location on circuit board 10 to which grounding is required.

In other embodiments, a receiving cavity is provided in the insulating plate 30 and the electrical connector 40 is provided in the receiving cavity.

In some examples, the insulating plate 30 is provided with a through hole for communicating the receiving cavity with the outside, and the electrical connector 40 is connected with the circuit board 10 and the grounding assembly 20 through the through hole to realize grounding of the circuit board 10. The effect is similar to the effect of providing the through hole or the notch 302 on the insulating plate 30 provided with the accommodating groove 301, and also aims to pertinently provide the electric connecting member 40, reduce the damage rate of the electric connecting member 40, and prolong the service life of the electric connecting member.

In some embodiments, as shown in fig. 2 and 3, the grounding assembly 20 includes a grounding spring 201, and the electrical connector 40 is electrically connected to the grounding spring 201 of the grounding assembly 20 for grounding the circuit board 10; electric connector 40 and ground connection shell fragment 201 are under connected state, ground connection shell fragment 201 is in deformation state, be in deformation state at ground connection shell fragment 201, can have a trend of kick-backing, this resilience force makes ground connection shell fragment 201 inseparabler with electric connector 40's contact, finally ground connection subassembly 20 and electric connector 40's connection performance is better, can effectively avoid the electric connector 40 and ground connection subassembly 20 between the connectivity relatively poor, the bad condition of contact that leads to.

In some embodiments, the insulating plate 30 may be made of a material having a certain hardness, such as PC.

In some embodiments, the electrical connector 40 has a certain hardness, and can deform the grounding elastic piece 201 by itself, and keep the grounding elastic piece 201 in a certain deformed state, at this time, the hardness of the material of the insulating plate 30 may not be specifically limited, and a material with a lower hardness, such as a PP material, may also be used, so as to improve the selectivity of the insulating plate 30. So as to realize the connection stability of the grounding elastic sheet 201 and the electric connector 40.

In other embodiments, the hardness of the electrical connector 40 itself is not enough to deform the grounding elastic sheet 201, or the grounding elastic sheet 201 cannot be kept in a certain deformation state, at this time, other auxiliary components are needed to apply force to the grounding elastic sheet 201, so that the grounding elastic sheet 201 is deformed and kept in a certain deformation state, and then the auxiliary components press a part of the electrical connector 40 in a position between the grounding elastic sheets 201, so as to achieve the connection stability between the grounding elastic sheet 201 and the electrical connector 40.

In a specific example, as shown in fig. 3, the insulating plate 30 includes a body and a support portion 303 from which the body protrudes, the electrical connector 40 includes a second connection end 402, the insulating plate 30 is configured to press the second connection end 402 to connect with the grounding elastic sheet 201 through the support portion 303, so that the grounding elastic sheet 201 maintains a deformed state, and the electrical connector 40 extends toward the support portion 303 of the insulating plate 30 and extends to an end surface of the support portion 303 away from the body, so that when the support portion 303 of the insulating plate 30 is connected with the grounding elastic sheet 201, a connection point between the support portion 303 and the grounding elastic sheet 201 is located between the support portion 303 and the grounding elastic sheet 201. Above-mentioned setting, electrical connector 40 is better with grounding component 20's connectivity, can effectively avoid contact failure, leads to the not good condition of ground connection performance.

In some embodiments, electrical connector 40 is an electrical connector, i.e., a sheet, such as a copper foil or other metal sheet. The electrical connection of the electrical connection sheet is better. On the other hand, the electrical connection sheet also has a function of assisting heat dissipation.

In some embodiments, the area of the insulating board 30 on which the electrical connection sheet is disposed is not less than 70% of the area of the side of the insulating board 30 away from the circuit board 10, and since the electrical connection sheet is usually made of metal foil, the heat dissipation performance of the electrical connection sheet is better than that of the insulating board 30, and when the area of the insulating board 30 on which the electrical connection sheet is disposed is not less than 70% of the area of the side of the insulating board 30 away from the circuit board 10, the heat dissipation performance of the electrical connection sheet can ensure the heat dissipation performance required by the nearby circuit. This setting can make the radiating effect of electric connection piece further improve.

In some of these examples, electrical connection 40 employs a copper foil. In a specific example, when a copper foil is used, the copper foil may be provided with a smaller size to achieve connection between the circuit board 10 and the ground assembly 20. In other examples, the copper foil may be sized larger so that the electrical connection between the circuit board 10 and the ground assembly 20 is maintained when the copper foil is locally damaged. Other metal foils may be used as electrical connections.

In other embodiments, electrical connections 40 may also employ electrical leads, and the like. In a specific example, the number of the electrical conductors is at least one, and in a case that the number of the electrical conductors is large, the electrical conductors can be mutually spare, so that when one or a part of the electrical conductors is damaged, the electrical connection between the circuit board 10 and the grounding assembly 20 can be maintained.
