The connecting shell 5 is provided with two, one end of the connecting shell 5 is provided with a butt joint part, and the two butt joint parts of the connecting shell 5 are respectively connected in the butt joint holes 3 at the left end and the right end of the main shell 1. Wherein, the outer side of the butt joint part on the connecting shell 5 is provided with an external thread matched with the internal thread in the butt joint hole 3, so that the butt joint part of the connecting shell 5 is detachably connected in the butt joint hole 3 at the end part of the main shell 1 through the thread.
A through groove into which the cable 6 is inserted is provided in the connection housing 5, and the end of the cable 6 is inserted into and inserted into the connection housing 5 through the through groove. The inner conductor 2 of the cable 6 extends outside the butt section of the connection housing 5. When the connection housing 5 is mounted at the end of the main housing 1, the inner conductor 7 of the cable 6 in the connection housing 5 extends into the insertion hole 4 of the adjacent inner conductor 2 through the mating hole 3 of the main housing 1. In this way, the inner conductors 7 in the two connection housings 5 are connected to the inner conductor 2 of the main housing 1, so that the interconnection of the inner conductors 7 of the two cables 6 is achieved.
When the two connection housings 5 are connected to the left and right ends of the main housing 1, respectively, the cables 6 in the two connection housings 5 are disposed coaxially with the main housing 1, and the inner conductors 7 of the cables 6 are aligned with the inner conductors 2 of the main housing 1. In addition, the inner diameter of the insertion holes 4 at the two ends of the inner conductor 2 is equal to the outer diameter of the inner conductor 7 of the cable 6, so that when the inner conductor 7 of the cable 6 extends into the insertion hole 4 of the inner conductor 2, the inner conductor 7 of the cable 6 is in close contact with the inner conductor 2 of the main shell 1, and the connection performance is ensured.
