When the conductive component 24 After being inserted into the wire connection hole 21 , the through hole 241 is linearly corresponding to the insertion hole 23 . The conductive elastic piece 25 is formed by bending another conductive piece into a substantially U shape, and a bent portion 251 is formed at one of the free ends to bend inward at an angle. The outer dimension of the conductive elastic piece 25 is smaller than that of the conductive component 24 Space size, but the width of the conductive elastic piece 25 is greater than the lateral width of the through hole 241 of the conductive component 24, therefore, after the conductive elastic piece 25 is placed in the inner space of the conductive component 24, the bent portion 251 is located at the corresponding through hole 241 Position; after the conductive elastic piece 25 and the conductive component 24 are combined, they are put into the wire connection hole 21 of the fixing seat 13 together, so that the through hole 241 corresponds to the insertion hole 23 in a straight line.
