Accompanying drawing 2 is the three-dimensional exploded schematic view of the utility model;

Accompanying drawing 3 is a schematic view of another perspective of Fig. 2 .

Detailed ways:

Below in conjunction with accompanying drawing, the utility model is further described:

As shown in accompanying drawings 1 to 3, the utility model mainly includes a first insulating body 1, a second insulating body 2 and a casing 3. The first insulating body 1 is formed with two USB interfaces 12, and the two USB interfaces 12 Corresponding terminals are implanted inside; a MINDIN interface 22 is molded on the second insulating body 2, and corresponding terminals are implanted in the MIN DIN interface 22.

In the utility model, the first insulating body 1 and the second insulating body 2 are stacked, and a semi-closed slot 11 is provided on the stacking surface of the first insulating body 1, while the stacking surface of the second insulating body 2 There is a buckle part 21 that matches the slot 11 of the first insulating body 1, and the buckle part 21 is inserted into the slot 11 to realize positioning and hooking, so that the two insulating bodies are combined into a whole; then the shell 3 wraps the second An insulating main body 1 and a second insulating main body 2 strengthen the connection between the two insulating main bodies, and have the functions of protection and connection.

In this embodiment, the slot 11 of the first insulating body 1 is configured in an inverted "eight" shape, and the left and right inner surfaces of the slot 11 are relatively obliquely retracted; the left and right sides of the corresponding buckle part 21 of the second insulating body 2 are inclined Expanding outward, the buckle portion 21 is matched and inserted into the slot 11 , and is positioned by the inner bottom of the slot 11 . The structure realizes the buckle connection, and the assembly is convenient and fast, and after the buckle is inserted, the inverted "eight" structural design is used to realize the hooking of the two insulating bodies without separation. When assembling, the buckle part 21 of the second insulating body 2 is inserted from front to back, and the depth of its insertion into the slot 11 is limited by the inner bottom of the slot 11, that is, the rear end of the buckle part 21 is in contact with the inner bottom of the slot 11 after being inserted. The end supports the top, and the front end of the second insulating body 2 is just flush with the front end of the first insulating body 1 .

Of course, in the present utility model, the slot 11 and the buckle part 21 can also be designed as a "T" shape, a "Y" shape or a "C" shape, etc., which can be plugged in and hooked up, and a combined structure can also be obtained. body.
