External device-to-external device connector for wireless communication devices

An external device-to-external device connector for a wireless communication base station, wherein the external device-to-external device connector is configured to electrically connect two spaced external devices together, and comprises:

• two interface members, each of which comprises an inner contact part, an insulating layer and an outer housing sequentially from inside to outside in the radial direction, wherein the outer housing of the interface member comprises a coupling member connecting portion and an external device connecting portion that are connected with each other, and the external device connecting portion is configured to be connected to an external device;
• and
• a coupling member, configured to connect the two interface members together and comprising an inner conductor part, an insulation part, two outer conductor parts, and an outer housing sequentially from inside to outside in a radial direction, wherein the inner conductor part receives and holds the ends of inner contact parts of the two interface members at both ends, and the insulation part is configured to space the inner conductor part from the outer conductor part, the ends of the two outer conductor parts are received and held in the coupling member connecting portion of the outer housing of the interface member, and the outer housing is configured to hold the two outer conductor parts and the insulating part;
• wherein the inner conductor part and the insulation part of the coupling member are held together by the concave-convex fitting parts opposite to each other, and there is a first gap between the concave-convex fitting part of the inner conductor part and that of the insulation part, which allows the inner conductor part to have radial displacement relative to the insulation part;
• or, the outer housing and the insulating part of the coupling member are held together by the concave-convex fitting parts opposite to each other, and there is a second gap between the concave-convex fitting part of the outer housing and that of the insulating part of the coupling member, which allows radial displacement of the insulating part relative to the outer housing of the coupling member.
