Description

Connection device for electronic device

The utility model relates to a kind of connector of the electronic device that is used to peg graft, mainly be at existing connector, engaging between its terminal and pedestal manyly places with mechanical clamping drawing, or fix clamping in the mode of punching press, so not only easy part of damage, and processing trouble are a kind of connector of ad hoc meter, be convenient to combining between terminal and pedestal, and easy to process.

Use connector grafting electronic device very convenient, but still having, its structure needs improvements, as shown in Figure 6, it is a kind of existing connector construction, mainly be provided with a pedestal 40 with many slots arranged side by side 41, in pedestal 40, be inserted with terminal 50, terminal 50 mainly is to be provided with the arc surface 51 of bending on top to rabbet with printed circuit board (PCB), be provided with protruding grain 54 in pin 501 inboards, in terminal 50 inserts in slot 41, can press from both sides (not shown) by tweezer is pulled out by pin 501 terminal application of force P1, simultaneously impose a power P2 at pin 501 near pedestal 40 root edge portions again, dash and be provided with bending recess 52, so that it can temporarily be solidly plugged in the perforation of printed circuit board (PCB) on production line, but the structure of this kind connector because of before, back secondary application of force P1, P2, so procedure extremely bothers, last time application of force P1 fixed with pin 501 drawings of tweezer folder clamping terminal 50, all made the terminal 50 terminal catcher marks 53 that produce, so easy touching promptly fractures, Chang Yi is damaged.

As shown in Figure 7, it does not give fixing structure for a kind of the need again with tweezer folder drawing end pin, after terminal 70 inserts pedestal 60 inside, an indenture 61 is directly gone out to bestow a power P3 towards the tool (not shown) in both sides at pedestal 60, inboard at pedestal 60 sidewall indentures 61 is then gone out a protuberance 63 relatively, it is fixing to hold pin 62 to clip, end pin 62 ends still need dash and be provided with bending recess 64 to fix with printed circuit board (PCB), because of impacting the mode of pedestal 60 mounting board terminals 70, pedestal 60 is damaged and the increase substandard products, and also higher towards the manufacturing cost of tool, therefore this structure utmost point is waited to improve.

Main purpose of the present utility model is: a kind of electronic device connector is provided, it is provided with a plurality of through holes in the pedestal both sides, be provided with the bending protuberance at terminal with respect to the side through hole place, so in the time of in terminal inserts pedestal, this bending protuberance can embed in the side through hole and fix, all very convenient in assembling and making, also can find out whether really assembling location of terminal by the pedestal side.

Another purpose of the present utility model is: a kind of connector is provided, and it directly is provided with embedding in the terminal side of the pin of terminal and colludes, and makes to be difficult for dropping out after inserting printed circuit board (PCB), can exempt the existing substandard products that caused in the punching mode and the procedure of trouble.

A purpose more of the present utility model is: a kind of connector is provided, and it forms a tapered plane so that clamping face to be provided at the necking section on two-terminal top opposite side, can strengthen the clamping action to printed circuit board (PCB) really.

The connector that the utility model provides, mainly containing terminal and pedestal forms, wherein pedestal inside is provided with the inside groove of fixed terminal, end at inside groove then is formed with long and narrow pin groove, terminal upper portion forms the necking section to the inside gradually with the clamping printed circuit plate, then be provided with several protruding grains on pin, its key is:

The terminal middle position outwards is formed with the bending protuberance, and the opposite face in the terminal necking section forms tapered plane to contact really with the printed circuit plate; Pin one side directly is formed with block embedding colludes, and is located for being inserted on the printed circuit board (PCB).

The pedestal both sides are provided with through hole with respect to the position of terminal bending protuberance and head into fixing for the bending protuberance.

The following effect of the utility model tool:

1. be provided with through hole owing to the utility model in the pedestal both sides, the bending protuberance of mating terminals, can move certainly after terminal inserts pedestal fixes, and simultaneously protruding grain also can be strengthened the effect of firm terminal, and is not only firm and very convenient in assembling.

2. the utility model is exempted and the clamping facility to be set or towards tool, so can reduce manufacturing cost.

3. the utility model owing to needn't impact pedestal so can reduce spoilage, needn't dash behind the assembling terminal in addition again and establish the fixedly bending recess of usefulness, so very practical when assembling.

Further specify architectural feature of the present utility model and purpose below in conjunction with drawings and Examples.

Brief Description Of Drawings:

Fig. 1 is the section of structure of the utility model connector.

Fig. 2 is the terminal structure figure of the utility model connector.

Fig. 3 is the base structure figure of the utility model connector.

Fig. 4 is the end view of the utility model connector.

Fig. 5 is the combination schematic diagram of the embodiment of the utility model connector.

Fig. 6 is existing connector construction figure.

Fig. 7 is the structure chart of existing another kind of connector.

As shown in Figure 1, 2, connector of the present utility model is made up of terminal 10 and pedestal 20, wherein the structure of terminal 10 as shown in Figure 2, necking section 16 is formed to the inside gradually at these terminal 10 tops, and be provided with tapered plane 11 at opposite face, be formed with bending protuberance 12 laterally at center section part, being provided with several protruding these figure of grain 13(is example in these bending protuberance 12 lower ends with two), then be formed with pin 15 in its lower end, this pin 15 directly is formed with block embedding in a side and colludes 14.

As Fig. 1, shown in Figure 3, pedestal 20 is provided with the inside groove 201 that is provided with for terminal in inside, then is formed with long and narrow pin groove 22 at the end of inside groove 201, and the position of inserting back bending protuberances 12 with respect to terminal 10 in the pedestal both sides is provided with through hole 21.

As Fig. 1, Fig. 2, shown in Figure 3, terminal 10 can insert from inside groove 201 tops of pedestal 20, because bending protuberance 12 is a slick and sly body, so when its tenesmus, be subjected to the pushing and pressing of pedestal 20 inwalls promptly to be subjected to an elastic force effect to be contained in inside groove 201, when pin 15 inserts pin groove 22, fasten in the inside of pin groove 22 with protruding grain 13 on the one hand, bend 12 of protuberances again and can spring into through hole 21 and make terminal 10 be mounted on pedestal 20 inside, easy to operate.

As shown in Figure 4, behind the terminal 10 assembling location, can find out that whether bending protuberance 12 has blocked the setting position, is convenient to visual test by side opening 21 places by pedestal 20 outsides.

As shown in Figure 5, when the utility model inserts printed circuit board (PCB) 30 at the pin 15 that makes connector, be subjected to embedding to collude 14 support and to make admittedly that connector is unlikely to come off, interleave fashionablely from two-terminal 10 tops when another printed circuit plate 31 again, necking section 16 pushing and pressing can be made the very driving fit of pegging graft that fits of tapered plane 11 and printed circuit plate 31.
