Abstract

The utility model discloses an inlaying grafting concatenation needle. A cuboid needle body is provided with a transition part and a faucet part, wherein the faucet part extends outwards from the needle body to form a notch which is in a similar round shape. Because the diagonal-position dimension of the similar round shape is less than the diagonal-position dimension of a square under the condition of same area, the difficulty of the spacing control of PCB plates is reduced, and meanwhile, the inlaying grafting process is caused to be more convenient.

Description

The continuous pin of pegging graft

Technical field

The utility model relates to the used continuous pin of grafting of grafting pin on a kind of electronic product, concretely, relates to the continuous pin of a kind of grafting.

Background technology

The continuous pin of pegging graft is mainly used in pegs graft to the pin of communications connector, the logical number device of mobile phone, computer CPU, employed in the market is that otch is square continuous pin mostly, because the chamfering otch is square, in the grafting process, client's printed circuit board (PCB) (PCB) plate hole spacing is required unusual strictness, the spacing of this strictness is bigger to the manufacture difficulty of pcb board, pcb board spacing in the market generally requires in 0.08 scope, and the spacing of low this scope is made then the certain difficulty degree; Also have on the market by manual pegging graft and finish, but, be difficult to adapt to industrialization demands because manual efficient is lower.

The utility model content

The purpose of this utility model provides the continuous pin of a kind of grafting, because under the same area situation, the diagonal-size of similar round is wanted the square diagonal-size of small offence, thereby reduces the difficulty of pcb board spacing control, also makes the grafting process more convenient simultaneously.

In order to reach above-mentioned technique effect, the utility model provides following technical proposals:

The continuous pin of a kind of grafting is provided with a transition part and a socket portion on a cuboid needle body, described socket portion is stretched out by needle body and forms a kerf, and described otch is a similar round.

Further, described cuboid needle body surface is provided with a plurality of projections, as is symmetrical cross projection, or beats wing type projection, or arrow type projection.

Further, described cuboid needle body surface is provided with annular knurl, also can be the profile of tooth lines.

Effect of the present utility model is: because the otch of socket portion is a similar round, under same area situation, the diagonal-size of similar round is wanted the square diagonal-size of small offence like this, thereby reduces the difficulty of pcb board spacing control, also makes the grafting process more convenient simultaneously.Use the contact pin machine of the utility model product can reach about 180 products assembling in one minute, and common artificial, prestissimo was 30 in one minute, and operating efficiency has improved 6 times, therefore, and relatively with the manual efficient that also improved greatly.

Fig. 3 is the utility model cuboid needle body socket portion schematic diagram;

Fig. 4 partly plays circle back socket portion schematic diagram for the utility model cuboid needle body.

Fig. 5 partly plays socket portion schematic diagram behind the wing for the utility model cuboid needle body.

Embodiment

Now the utility model execution mode is described further in conjunction with embodiment:

As Fig. 1, Fig. 2, shown in Figure 3, the continuous pin of pegging graft is: be provided with a transition part 2 and a socket portion 3 on a cuboid needle body 1, socket portion 3 is stretched out by needle body 1 and forms a kerf 5.As shown in Figure 2, the otch 5 of continuous pin is square in the prior art, has certain corner angle.As shown in Figure 3, the otch 6 of the continuous pin of the utility model is a similar round, and all the other sides of socket portion 3 are just comparatively slick and sly with being connected of otch 6 like this, thereby do not have corner angle to occur.As Fig. 4, shown in Figure 5, pin can also carry out some improvement according to concrete production technology needs continuously, for example, cuboid needle body 1 is beaten circle, perhaps with 1 dozen of wing of cuboid needle body, promptly extends outward projection 7 on cuboid needle body 1.Can certainly press annular knurl 4 in the subregion of cuboid needle body 1 or be pressed into profile of tooth.

Thus, all improvement in the prior art scope to cuboid needle body 1 all drop within the utility model protection range.

Claims (3)

1, the continuous pin of a kind of grafting is provided with a transition part and a socket portion on a cuboid needle body, described socket portion is stretched out by needle body and forms a kerf, and it is characterized in that: described otch is a similar round.

2, the continuous pin of grafting according to claim 1 is characterized in that: described cuboid needle body surface is provided with a plurality of projections.

3, the continuous pin of grafting according to claim 1 is characterized in that: described cuboid needle body surface is provided with annular knurl.
