Description

Technical Field

[0001] The utility model relates to the technical field of an electric connector, in particular to a cable bidirectional assembly type plug electric connector. Background Art

[0002] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 , which represents the structure of the plug electrical connector of the prior art. The plug electrical connector is usually connected to multiple cables to transmit electronic signals. Generally speaking, the cables extend from the rear end of the plug electrical connector to the rear, but under certain space configuration requirements, the cables must extend from the side of the plug electrical connector, so that the cables and the plug electrical connector form an L-shaped configuration.

[0003] like Figure 1 and Figure 2 As shown, one end of a plurality of cables C is soldered to a soldering pad PD on a circuit board P, and the plurality of cables C extend to the left of the plug electrical connector E. The front shell H1 and the rear shell H2 of the plug electrical connector E are assembled to form a shell H so that the circuit board P is positioned in the shell H. A cable outlet H3 is formed on the left side of the shell H, and the plurality of cables C extend from the cable outlet H3 to the outside of the shell H.

[0004] like Figure 3 and Figure 4 As shown, a cable outlet H3 is formed on the right side of the housing H, and a plurality of cables C extend from the cable outlet H3 to the outside of the housing H, so that the plurality of cables C extend to the right of the plug electrical connector E.

[0005] In the above-mentioned prior art, for the plug electrical connector E with the cable C extending to the left, the cable outlet H3 is formed on the left side of the housing H, and for the plug electrical connector E with the cable C extending to the right, the cable outlet H3 is formed on the right side of the housing H. Since the housing H of different shapes must be used when the cable C extends to the left or right, two sets of molds must be made to correspond to the housings H of different shapes. This will increase the manufacturing cost of the plug electrical connector, and the housings H of different shapes will also increase the burden on component management. Utility Model Content
