Description

Connector

The utility model relates to a kind of connector, is meant the connector that a kind of card connector that is fit to have straight type terminal uses especially.

See also Fig. 1, it is that existing card connector is assemblied in the schematic diagram on the circuit board.Wherein, card connector 2,2 ' terminal 21,21 ' bending after be welded on the circuit board 1.But in fact the manufacturing technology difficulty of this class terminal is very big, and the terminal Chang Wufa after the bending reaches and aligns and the requirement of coplane, causes the empty weldering of terminal very high with the ratio of solder joint adhesion.Have, card connector is comparatively expensive again, must tear open and injures terminal when pulling out again easily if be welded with flaw, and manufacturing cost is increased.

A kind of method of improvement is to avoid directly terminal being welded on the circuit board, but card connector and circuit board are electrically connected by a connector, as shown in Figure 2, with connector 3,3 ' terminal pins 31,31 ' be welded in circuit board 1, connector 3,3 ' end face be provided with several jacks, for card connector 2,2 ' terminal 21,21 ' insertion.Therefore if there is the welding flaw only need change connector rather than card connector, connector comparatively cheapness can reduce cost.No. the 80207449th, relevant patent Taiwan, No. 81216447, No. 81217278, No. 82205600, No. 83202199, No. 83107162, No. the 4818239th, No. 83208140 patent application and the U.S., No. 4878856, No. 4810203, No. 5149276, No. 5176523, No. 5286207, No. 5290174, No. 5324204, No. 5334046 patent.

Yet this kind connector still has following shortcoming: as shown in Figure 2, connector terminal pins 31,31 ' extend to both sides add connector 3,3 ' be arranged side by side, so its area occupied is bigger, also is unfavorable for the arrangement of computer inner space.Have, connector 3,3 ' priority is placed on welding on the circuit board 1 again, and the placement program is two roads, so operation is comparatively loaded down with trivial details.In addition, connector 3,3 ' terminal pins have four rows, the row of two in the middle of it is subject to narrow space interval so inspect repair welding and be difficult for.

The purpose of this utility model is to provide a kind of connector, and its area occupied is less, is easy to inspect repair welding.

The purpose of this utility model is to realize like this, a kind of connector promptly is provided, be used to electrically connect circuit board and card connector, it comprises: at least one elongate body, an one side are offered several for the corresponding jack that inserts of the straight type terminal of above-mentioned card connector; Several are connected terminal, and correspondence is arranged in the above-mentioned jack and does electrically to contact with the card connector terminal of above-mentioned insertion jack one end, extends in the other end of the terminal pins of above-mentioned linking terminal by above-mentioned jack, is electrically connected with the foregoing circuit plate.

The advantage of the utility model connector is, its compact conformation takies less space, assembles easyly, inspects and repairs easily, and practicality is good.

Below in conjunction with accompanying drawing, embodiment of the present utility model is described, wherein:

Fig. 1 is assemblied in the schematic diagram of circuit board for existing card connector;

Fig. 2 is used in double-deck card connector schematic diagram for existing connector;

Fig. 3 is that first, second connector of the utility model merges user mode figure;

Fig. 4 is a double-deck card connector stereogram among Fig. 3;

Fig. 5 is first, second connector stereogram of the utility model;

Fig. 6 is integrated first, second connector user mode of the utility model figure.

Please consult Fig. 3 and Fig. 4 simultaneously, Fig. 3 is used in the end view of double-deck card connector for the utility model connector, Fig. 4 illustrates the stereogram of double-deck card connector among Fig. 3, and wherein,

connector

4,6 makes card connector 2,2 ' be electrically connected with circuit board 1.

See also Fig. 5, connector of the present utility model has two kinds of patterns, be respectively first connector 4 and second connector 6, first connector 4 has elongate body 42, two socket holes are offered in its side, are respectively odd number socket hole: first jack 441, the 3rd jack 443 ... and even numbers socket hole: second jack 442, the 4th jack 444 ...The linking terminal is set in above-mentioned jack, be connected terminal and in above-mentioned jack, extend corresponding terminal pins respectively, be respectively odd number row terminal pins: the first terminal pin 461, the 3rd terminal pins 463 ... and even numbers row terminal pins: second terminal pins 462, the 4th terminal pins 464 ... wherein the first terminal pin 461 is extended by first jack 441, second terminal pins 462 is extended by second jack 442, and the 3rd terminal pins 463 is extended by the 3rd jack 443 ...These terminal pins bend the back in the same way and are drawn by body 42 1 sides.As seen from Figure 5, even numbers row's terminal pins and odd number row terminal pins are staggered, because odd number row terminal pins all aligns odd number socket hole, therefore even numbers row terminal pins must be offset when extending, the spacing of supposing per two odd numbers row terminal pins is D, and then the side-play amount of relative its adjacent odd number row terminal pins of even numbers row terminal pins is D/2.

Second connector 6 also has an elongate body 62, is formed with depressed part 622 in body 62 bottom sides, and correspondence is held first connector 4.Body 62 side 621 above depressed part 622 is provided with two socket holes, be respectively odd number socket hole: first jack 641, the 3rd jack 643, and even numbers socket hole: second jack 642, the 4th jack 644 ... extending corresponding terminal pins respectively in the above-mentioned jack (does not show, because of the side 621 at the above-mentioned dorsad jack of the bearing of trend place of terminal pins is covered), be respectively odd number row's terminal pins and even numbers row terminal pins, arrangement mode as for terminal pins, spacings etc. are identical with the terminal pins of first connector 4, its explanation of Therefore, omited.

Each establishes a

lug

48,68 integratedly at the two ends of the first connector body 42 and the second connector body 62, in order to cooperate with bonding pad 5

body

42,62 is combined.As shown in Figure 3, first and

second connector

4,6 terminal pins are welded on the circuit board 1, and several jacks that its side is provided with can supply card connector 2,2 ' terminal 21,21 ' correspondence insertion, with the termination contact that is connected in the jack, make card connector 2,2 ' can electrically connect with circuit board 1.

Because jack is all towards card connector, so the terminal of card connector is straight type, do not need bending, makes simple and easy, with low cost.Because first,

second connector

4,6 abuts in together, therefore can reduce area occupied again, improve the utilance of computer inner space.First,

second connector

4,6 uses bonding pad 5 to link earlier before assembling, therefore the formality that when assembling connector is placed on the circuit board 1 only has together, can weld its terminal pins then, the terminal of parallel again insertion card connector, when saving the assembler, after first,

second connector

4,6 combinations, its terminal pins all stretches out, its solder joint obviously can be inspected, and repairs simpler and easy.

See also Fig. 6, the embodiment that its another kind that the utility model connector is shown changes, wherein the body of first, second connector is formed in one and makes, and therefore lug, bonding pad are not set.In addition, if card connector is individual layer (as only being provided with card connector 2), then in Fig. 3, only need to use first connector 4 to get final product, or cushion block is set below card connector 2 in addition increases its height, cooperate second connector 6 to use then, its occupation mode is flexible.
