Abstract

The utility model relates to a D-type connector, comprising a metal casing, a plastic cement casing, terminals and a back plastic cover. Terminal holes on the plastic casing are arranged in three rows in parallel, and the terminal holes are used for inserting a plurality of terminals. The utility model is characterized in that the back end of the terminal of the connector is provided with a rectangular adhesion portion and/or an electrically-conductive foot which is extended from the proper position of the adhesion portion vertically and downwards, and after the adhesion portion at the back end of the terminal is integrally combined, the shape that double rows are parallel is formed.

Description

D-type connector

The utility model relates to a kind of D connector, the D type electric connector that particularly a kind of its terminal is arranged by high density.In this D connector, its terminal rear end has an adhesive part and a conductive feet, and is double kenel arranged side by side after the entire combination; Can select to fix in the surface adhering mode or in the spot welding mode, make to link between this connector terminal and circuit board and fix, and can shorten overall structure occupied space on circuit board, and be convenient to the arrangement and the layout of the printed wire on the circuit board, to promote the service efficiency and the economic worth of product.

Press, present known high density D connector, the terminal 02 that wherein is installed in the plastic housing 01 as shown in Figure 1 is to settle in three rows mode arranged side by side, yet the arrangement in this terminal 02 and circuit board 03 junction of its correspondence also is the kenel (as shown in Figure 1) of three row's block forms.The shortcoming of above-mentioned known configurations mainly the printed wire on circuit board 03 031 arrangement with arrange very difficulty, because this known construction is with three rows fixedly kenel arranged side by side, wherein certainly will cause the position, hole in the first and the 3rd row's conductive feet hole 032 overlapping phenomenon to be arranged at longitudinal direction, thereby the printed circuit on circuit board 03 031 comparatively intensive and be difficult to the configuration, be easy to produce short circuit; Moreover, when terminal 02 rear end of this known connector is fixed on the circuit board 03 in three rows mode arranged side by side, will make the depth length increasing of this connector and occupy board area more, and can not meet the designing requirement of " short; little; light; thin " now, this known configurations and can't using 03 of terminal 02 and circuit board with the fixing kenel of surface adhering mode, because wherein the two row's conduction adhesive part 033(that arrange forward lapping on the circuit board 03 are shown in the dotted line among Fig. 1) after its adhesion, be easy to link to each other and can't use, thereby be unfavorable for the actual use of product.

For improving the structural shortcoming of above-mentioned known D connector, the utility model proposes a kind of improved D connector, it has can select to use some bar or surface adhering mode to fix, and can dwindle its depth length, and be easy to the effects such as route on its pairing printed circuit of arrangement.

Therefore, main purpose of the present utility model is providing a kind of D connector, and being arranged in of its terminal is three rows in the plastic housing, and rear end and circuit board junction are that two rows are arranged side by side, so that arrange the printed circuit on the circuit board.

Of the present utility model time a purpose is providing a kind of D connector, and it can dwindle the depth length of this connector.

A purpose more of the present utility model is providing a kind of D connector, and wherein the fixed form between terminal and circuit board may be selected to be the fixed form of spot welding or surface adhering.

For achieving the above object, the utility model is embodied as a kind of D connector, comprises metal-back, plastic housing, terminal and back vinyl cover, and wherein the system of the terminal hole on the plastic housing is highdensity three rows side by side, for a plurality of terminals of planting; It is characterized in that: the terminal rear end of this connector has the adhesive part of a rectangle and/or has extended a conductive feet vertically downward in the appropriate position of this adhesive part, and forms double kenel arranged side by side after the adhesive part entire combination of this terminal rear end.

In order making the purpose of this utility model, shape, structural feature and effect thereof there are further understanding and understanding, now are described in detail as follows for going up the embodiment conjunction with figs.:

Fig. 1 is the schematic perspective view of known high density D connector.

Fig. 2 is a unitary construction three-dimensional exploded view of the present utility model.

Fig. 3 is a side-looking flat assembly drawing of the present utility model.

Fig. 4 is the view plane schematic diagram of going up of the present utility model.

See also shown in accompanying drawing 2 and the accompanying drawing 3, D connector of the present utility model comprises metal-back 1, plastic housing 2, terminal 3 and back vinyl cover 4, and wherein the terminal hole on plastic housing 2 21 is to be three rows high density kenel arranged side by side, for a plurality of terminals 3 of planting; And have the adhesive part 31 of a rectangle in terminal 3 rear ends of this connector and/or extend a conductive feet 32 in the appropriate position of this adhesive part 31 vertically downward, and after adhesive part 31 entire combination of these terminal 3 rear ends, form double kenel arranged side by side.

Please cooperate Fig. 2 and shown in Figure 3 again, when the utility model assembling is used, the connected mode that 3 visual future of terminal wherein and circuit board are 5, and before assembling, promptly cut off conductive feet 32 or adhesive part 31 earlier, the terminal 3 that makes this connector with can at random select being connected of 5 of circuit boards in the surface adhering mode or with two kinds of kenels such as the spot welding mode are fixing, to increase its practicality; In addition, the utility model is owing to be to make the overall alignment of terminal 3 rear ends become double block form (as shown in Figure 4), thereby can shorten integrally-built depth length and space occupied on circuit board by more known three structures of arranging formulas, and, the layout of the printed wire 51 of the utility model on its corresponding circuit board 5 can not occur having the fixedly kenel and the printed circuit 51 that forward lap and can't be used in surface adhering to arrange difficult shortcoming as known three row's formulas.

In sum, D connector of the present utility model can have diversity really and select function of use, have again can reduce whole depth length and be convenient to arrange with the configuration circuit plate on the effect of printed circuit.

The foregoing description is only in order to illustrate a possible embodiments of the utility model D connector, for those of ordinary skill in the art, can partly carry out various equivalence variations to its detail structure or shape, but these variations all should be included in spirit of the present utility model and the scope.

Claims

1, a kind of D connector comprises metal-back, plastic housing, terminal and back vinyl cover, and wherein the system of the terminal hole on the plastic housing is highdensity three rows side by side, for a plurality of terminals of planting; It is characterized in that: the terminal rear end of this connector has the adhesive part of a rectangle and/or has extended a conductive feet vertically downward in the appropriate position of this adhesive part, and forms double kenel arranged side by side after the adhesive part entire combination of this terminal rear end.
