In addition, in some other embodiments, referring to fig. 15, a second slot 3300 for mating and inserting with the alignment guide protrusion 410 is opened inside the first female seat 3000 and the second female seat 4000, and the second slot 3300 is disposed above the first slot 3100; specifically, when the adapter 1000 is plugged into the second female socket 4000, the guiding portion 110 of the housing 100 and the plug connector of the connector 200 are butted against the second female socket 4000, the guiding portion 110 guides the plugging between the plug connector of the connector 200 and the first slot 3100 of the second female socket 4000, and when the plug connector of the connector 200 is plugged into the first slot 3100, the contact terminal 3200 is in contact with the upper terminal 221 and the lower terminal 222, so that the electrical conduction is realized.

The test adapter of this embodiment is through adopting the adapter 1000 of the above-mentioned first aspect embodiment, effectively improve test adapter 2000's plug life-span, satisfy its better electrical performance requirement, and simultaneously, be connected with other adapter 1000 through first female seat 3000, provide reliable connected mode, make test adapter 2000 connect convenient and fast more, and make and have good combination effect between test adapter 1000 and the test equipment.

A patch cord 5000 according to a third aspect of the present invention will be described below with reference to fig. 16 and 17.

Referring to fig. 16 and 17, the patch cord 5000 according to the third embodiment of the present invention includes the patch plug 1000 and the wire 6000 according to the first embodiment, one end of the wire 6000 is connected to the circuit board 300, and the other end extends outward and extends out of the housing 100; specifically, in the present embodiment, the wire 6000 may be a flat cable; the flat cable uses copper or aluminum as a conductor, so that signal transmission is realized.

Through adopting the adapter 1000 of above-mentioned first aspect embodiment, effectively improve the plug life-span of patch cord 5000, satisfy its better electrical performance requirement, simultaneously, be connected formation patch cord 5000 through wire material 6000 and adapter 1000, another adapter 1000 or test equipment can be connected to patch cord 5000 outwards stretching one end to improve patch cord 5000's commonality.

While embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that: various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
