The first board body 1111 is provided with a first fixing section 11111 and a first connecting section 11112. An insertion slot 11113 is formed at the end of the first connecting section 11112. The second board body 1112 is provided with a second fixing section 11121 and a second connecting section 11122. The second fixing section 11121 is fixedly connected to the first fixing section 11111. The first connecting section 11112 and the second connecting section 11122 are arranged corresponding to each other and an installation gap 11119 is formed therebetween. A plugging board 11123 is fixedly connected to the end of the second connecting section 11122. The plugging board 11123 is plugged and fixed in the insertion slot 11113.

[0042] The installation gap 11119 formed between the first connecting section 11112 and the second connecting section 11122 is used for installing an elastic contact member. One end of the plugging board 11123 is fixed to one end of the second connecting section 11122. The other end of the plugging board 11123 is plugged and fixed in the insertion slot. The first connecting section 11112 and the second connecting section 11122 can be fixed by the plugging board 11123, the distance between the first connecting section 11112 and the second connecting section 11122 can be restricted, and further the deformation of the installation gap 11119 can be prevented. The structure is simpler, and the contact effect between the elastic contact member installed on the first connecting section and the second connecting section and other mating terminals can be improved.

[0043] In one embodiment, a butt step 11124 is formed at the side end of the plugging board 11123 so that a plugging head 11125 is formed at its end. The plugging head 11125 is inserted and fixed in the insertion slot 11113. The volume of the end of the plugging board 11123 is reduced, which is convenient for plugging and improves the stability of plugging.

[0044] In one embodiment, the butt step 11124 abuts against the first connecting section 11112. A limiting block 11126 is arranged on the plugging head 11125.

The cross section of the abutting step 11124 abuts against the bottom of the first connecting section 11112. Arranging the abutting steps 11124 on both sides makes the plugging more stable when plugging, preventing deflection on the side without the abutting step 11124.

[0047] In some embodiments, limiting blocks 11126 are symmetrically arranged on both sides of the end of the plugging head 11125.

The cross sections of the two abutting steps 11124 both abut against the bottom surface of the first connecting section 11112, and the longitudinal sections of the two abutting steps 11124 abut against the two side walls of the plugging board 11123, improving the stability of the plugging head 11125 inserted into the plugging slot. Both of the two limiting blocks 11126 are extruded and deformed, and are extruded on the limiting notch 11114, fixing the plugging board 11123 and the first connecting section.
