Abstract

The utility model provides a USB plug connector comprising a conductive terminal group, a supporting body and a shielding shell. The supporting body comprises an insulation tongue sheet which is arranged inside the shielding shell. The conductive terminal group and the supporting body are molded into an integrated whole. The conductive terminal group and the supporting body are molded into the integrated whole so that the manual inserting of the conductive terminal group and the riveting process are not needed, and the assembling process is reduced. Therefore, manual costs are reduced and production efficiency is enhanced. Besides, damage to the PIN is not caused so that percent of pass of products is ensured.

Description

A kind of USB plug connector

Technical field

The utility model relates to electric connector field, relates in particular to a kind of USB plug connector.

Background technology

Existing USB plug electroconductive terminal for connector group and supportive body are all independent manufacturings, by manual operation, the conducting terminal assembly is inserted in supportive body, by fixture, its conducting end subgroup being carried out the fourth of the twelve Earthly Branches afterwards presses to be fixed on supportive body, can there be the problem that PIN power is not enough, lack PIN of moving back in the process of production conducting end subgroup, the phenomenons such as conducting terminal fractures also easily appear in installation process, and it is various to assemble operation, the problems such as production cost height; Traditional slotting PIN structure is higher due to mould die requirement on machining accuracy in mould later stage maintenance in addition, workpiece is less, be easy to cause the damage of workpiece, and die cost increases, the formed product rate is low.

The utility model content

In order to solve the problems of the prior art, the USB plug connector that the utility model provides a kind of conducting end subgroup and supportive body to be formed in one.

The utility model provides a kind of USB plug connector, comprise conducting end subgroup, supportive body and shield shell, described supportive body comprises the insulation tongue piece, and described insulation tongue piece is located in described shield shell, and described conducting end subgroup and described supportive body are formed in one.

As further improvement of the utility model, described conducting end subgroup comprises contact site and weld part, and it is surperficial that described contact site is exposed to described insulation tongue piece; Described supportive body also comprises insulating plug, and described weld part is placed in described insulating plug.

As further improvement of the utility model, described conducting end subgroup comprises an earth terminal, and the weld part of described earth terminal is electrically connected to described shield shell.

As further improvement of the utility model, described conducting end subgroup also comprises two signal terminals and a power supply terminal, and the weld part of described signal terminal is electrically connected to described holding wire, and the weld part of described power supply terminal is electrically connected to described power line.

As further improvement of the utility model, described shield shell is provided with inwardly protruded locating piece, and described insulation tongue piece is provided with the groove corresponding with described locating piece position, and described locating piece is stuck in described groove.

As further improvement of the utility model, described locating piece is located at described shield shell near described insulating plug one end.

As further improvement of the utility model, described locating piece is at least one.

As further improvement of the utility model, described locating piece is four.

The beneficial effects of the utility model are: conducting end subgroup and supportive body are one-body molded, do not need manually to insert the conducting end subgroup and carry out the fourth of the twelve Earthly Branches and press operation, reduced the operation of assembling, thereby reduced cost of labor, improved production efficiency, and can not damage PIN, guarantee product percent of pass.

Embodiment

1-conducting end subgroup 2-supportive body 3-shield shell 11-contact site 12-weld part 21-insulation tongue piece 22-insulating plug 31-locating piece 211-groove.

As Fig. 1 to as shown in 3, the utility model discloses a kind of USB plug connector, comprise conducting end subgroup 1, supportive body 2 and shield shell 3, described supportive body 2 comprises insulation tongue piece 21, described insulation tongue piece 21 is located in described shield shell 3, and described conducting end subgroup 1 is formed in one with described supportive body 2.

In the present embodiment, adopt Insert Molding(vertical forming) molding mode directly with conducting end subgroup 1 together with supportive body 2 is molded over, do not need manually to insert PIN, riveting operation, fundamentally reduce process flow for assembling; Reduce cost of labor, improved production efficiency; Traditional slotting PIN structure is higher due to mould die requirement on machining accuracy in mould later stage maintenance in addition, workpiece is less, be easy to cause the damage of workpiece, and die cost increases, defective products produces in formed product; And Insert Molding forming technique mould does not have PIN casement benevolence, so there is not the fragile problem of PIN pin, is difficult for causing the increase of later stage die cost, good stability in the mould procedure for producing, and fraction defective is less.

Described conducting end subgroup 1 comprises contact site 11 and weld part 12, and described contact site 11 is exposed to insulation tongue piece 21 surfaces; Described supportive body 2 also comprises insulating plug 22, and described weld part is placed in insulating plug 22.

Described conducting end subgroup 1 bag expands two signal terminals, a power supply terminal, an earth terminal, and the weld part of signal terminal is connected with holding wire, and the weld part of power supply terminal is connected with power line, and the weld part of earth terminal is electrically connected to shield shell 3.

Described shield shell 3 is provided with inwardly protruded locating piece 31, and described insulation tongue piece 21 is provided with the groove 211 corresponding with locating piece 31 positions, thereby locating piece 31 is stuck in groove 211 shield shell 3 and supportive body 2 are fixed.

Described locating piece 31 is located at shield shell 3 near insulating plug 22 1 ends, and in this embodiment, locating piece 31 is four, is symmetricly set on shield shell 3 both sides, and what engage like this is more firm, and shield shell 3 is not easy to get loose, and works more reliable.

Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection range of the present utility model.
