These connectors include sockets, connectors, pin rows, terminals, etc., which usually provide electrical connections and / or mechanical support, such as connecting electronic components (such as integrated circuit chips), transmitting signals, providing power, etc. These connectors play a vital role on printed circuit boards, allowing different electronic components to be connected to each other to form a complete circuit system.

[0003] Among them, it was found through searching that the utility model patent with patent application number CN201920449276.6 discloses a circuit connection board, a printed circuit board assembly and an electronic device, wherein the circuit connection board comprises: a substrate, which is a plate with a through hole, and the substrate comprises an upper surface and a lower surface arranged opposite to each other in its thickness direction; a plurality of conductive members, which are arranged on the substrate at intervals, each conductive member comprises a main body and two conducting parts respectively connected to the two ends of the main body, the conducting part is an elastic member, and the main body is embedded in the substrate, one of the conducting parts is exposed on the upper surface, and the other conducting part is exposed on the lower surface;

[0004] When this structure is in use, multiple conductive parts are arranged on the substrate, and the two conductive parts of each conductive part can be exposed from the upper and lower surfaces of the substrate respectively, so that electrical connection between two stacked circuit boards can be achieved. However, this structure is not easy to clamp and position the circuit boards when in use, which makes it easy for the circuit boards to be disconnected during conduction. Utility Model Content

The first stopper and the second stopper are displaced due to the traction force when the circuit board is plugged in. At the same time, the first stopper and the second stopper are reset by the elasticity of the second connector and the first connector itself, so as to realize the function of clamping and positioning the circuit board, and ensure the stability of the installation of the circuit board. Through the setting of the limiting groove and the first positioning groove, the first connector and the second connector can be installed on the protective shell and the bottom plate for positioning, and the stability of the installation of the first connector and the second connector can be ensured. When the second connector is installed in the first positioning groove, the cross bar can extend into the second positioning groove, so as to improve the stability of the structure during installation.

Through the corresponding coordination of various structures, the first stop block contacts the bottom of the circuit board, and the second stop block can contact the top of the circuit board. The first stop block and the second stop block are displaced due to the traction force when the circuit board is plugged in. At the same time, the elasticity of the second connecting member and the first connecting member itself drives the first stop block and the second stop block to reset, thereby realizing the function of clamping and positioning the circuit board and ensuring the stability of the circuit board installation.

[0016] By setting the limiting groove and the first positioning groove, the first connecting member and the second connecting member can be positioned when installed on the protective shell and the bottom plate, ensuring the stability of the installation of the first connecting member and the second connecting member. When the second connecting member is installed in the first positioning groove, the cross bar can extend into the second positioning groove, thereby improving the stability of the structure during installation.
