Mini USB plug improvement of connector structure

[technical field]

The utility model relates to a kind of Mini USB plug improvement of connector structure, refers to the pin connector structure on a kind of MiniUSB of being applied to transmission line especially.

[background technology]

As shown in Figure 1, be the in-built schematic diagram of a kind of known connector, this connector is the pattern of Mini USB, and it comprises that a connector joint 1a and is electrically connected at the transmission line 2a of this joint 1a rear end; This joint 1a has an insulating base frame 10a, be provided with a plurality of terminal 11a in insulating base frame 10a, these terminals 11a end is extended by insulating base frame 10a rear end, and further be welded in copper foil circuit 120a place on the circuit board 12a, link by the copper foil circuit 120a of this circuit board 12a and the line stamen 20a welding of transmission line 2a then.After waiting, outside this insulating base frame 10a, coat layer of metal housing 13a again, and outside circuit board 12a, coat an insulation crust 14a who is connected between metal shell 13a and the transmission line 2a again, use forming a connector person.

But in the above-mentioned connector, owing to must pass through circuit board 12a again between the line stamen 20a of its terminal 11a and transmission line 2a as electric connection, so its cost height and manufacture process are comparatively numerous and diverse, the copper foil circuit 120a that also makes circuit board 12a easily because of the insulation crust 14a that is subjected to moulding under HTHP, cause the copper foil circuit 120a of circuit board 12a to come off, cause problems such as short circuit and no signal, off-line problem between transmission line 2a and circuit board 12a is also arranged simultaneously easily, and the electronic building brick on the circuit board 12a also damages to some extent because of HTHP easily.

Because the above-mentioned known problem that produces, creator of the present utility model satisfy be engaged in the sector for many years experience, and in line with excelsior spirit, the active research improvement has the generation of the utility model " Mini USB plug improvement of connector structure " then.

[utility model content]

A purpose of the present utility model is to provide a kind of Mini USB plug improvement of connector structure, mainly comprise insulating base frame, terminal group and metal shell, wherein insulating base system and terminal group one injection molding, make the insulating base frame front side be formed with a Plug Division, the contact jaw of terminal front end promptly is arranged in the place, Plug Division, the insulating base frame rear side then is formed with a backstop, the weldering tail end of terminal rear end is extended back from backstop, and between Plug Division and backstop, protrude out a middle block that is provided with at interval with backstop, in addition, the metal-back system is coated on the insulating base frame outside, and make the backstop of insulating base frame, middle block and metal shell inside are arranged with a confined space, install connection for electronic building brick.So when covering at metal shell on the insulating base frame, can make in electronic building brick is hidden in by coating fully.

By this, electronic building brick can be hidden in the confined space by coating fully, penetrates when coating an insulation crust when follow-up, can avoid thus electronic building brick in penetrating the coating process, be subjected to HTHP influence and damage.
