The base 12 is in a cylindrical shape as a whole, and the first connecting part 13 and the second connecting part 14 are respectively integrally formed at both ends of the base 12. The first connecting part 13 and the second connecting part 14 are both in the shape of rectangular plates, and the length direction of the first connecting part 13 and the second connecting part 14 is parallel to the length direction of the base 12. The plate surface of the first connecting part 13 and the plate surface of the second connecting part 14 are parallel to each other, and the connecting holes 11 are respectively located at the ends of the first connecting part 13 and the second connecting part 14 away from the base 12. The first connecting part 13 is arranged on the end surface of the base 12, and the side of the first connecting part 13 away from its own connecting hole 11 is located on the diameter of the end surface; the end of the second connecting part 14 away from its own connecting hole 11 is arranged on the outer wall of the base 12, and is located at the end of the base 12 away from the first connecting part 13.
[0032] refer to Figure 2 and Figure 3 The housing 2 includes an integrally formed mounting plate 23 and a connecting pipe 24, and the housing 2 is made of insulating material, and in this embodiment, a plastic material is used. The mounting plate 23 is in the shape of a diamond plate as a whole, and the surface of the mounting plate 23 is perpendicular to the length direction of the substrate 12. The mounting holes 21 are respectively provided at both ends of the length direction of the mounting plate 23. A screw sleeve 22 is provided in the mounting hole 21, and the screw sleeve 22 and the mounting plate 23 are connected by interference fit, so that the screw sleeve 22 can be stably arranged in the mounting hole 21. The connecting pipe 24 is in the shape of a cylindrical tube as a whole, and the length direction of the connecting pipe 24 is perpendicular to the surface of the mounting plate 23, and the center of the mounting plate 23 is located on the axis of the connecting pipe 24. The connecting pipe 24 is close to the second connecting portion 14 and the relatively arranged clamping arms 25, and the two clamping arms 25 are both located on the length direction surface where the first connecting portion 13 is located. A clamping portion 251 is relatively extended from one end of the clamping arm 25 away from the first connection portion 13. When the connection terminal 1 is located in the connection tube, the clamping portion 251 can abut against the end surface of the base 12 close to the second connection portion 14. Two grooves 26 are cut on the connection tube 24 based on the same side of the two clamping arms 25, and a clearance groove 27 for the second connection portion 14 is cut on the other same side of the two clamping arms 25. Both the groove 26 and the clearance groove 27 are open toward the second connection portion 14, so that the connection terminal 1 can be installed in the housing 2 by opening the connection tube 24, and the connection terminal 1 can be prevented from rotating in the housing 2 to the greatest extent.
