Abstract

The utility model provides an electronic component installation positioning comb, which comprises a comb handle and comb teeth, wherein the quantity of the comb teeth is more than the quantity of welding pins in one row of welding pins of an electronic component to be installed; a distance alpha between every two comb teeth is equal to the distance between every two welding pins of the electronic component; and the shape of a top end of each comb tooth is a leftward or rightward hook shape in the horizontal direction, an L-shaped comb groove is formed between every two adjacent comb teeth, the width b of an inlet of the L-shaped comb groove is more than that of each welding pin, the height c of the bottom of the L-shaped comb groove is higher than the thickness of each welding pin, so the welding pins can be easily guided into the comb groove. The positioning comb can simultaneously adjust the positions of slope welding pins, so the welding pins can be aligned to a welding disc hole. The positioning comb has a simple structure and is convenient to operate, and the assembling efficiency of the long row multi-welding-pin long-pin component can be effectively improved.

Description

The long pin electronic devices and components of a kind of many legs installing and locating comb

Technical field

The utility model belongs to the electronic devices and components assembly tooling.Be specifically related to a kind of frock that the long pin components and parts of many legs is navigated to fast the corresponding card address of printed board.

Background technology

The use of electronic component in electron trade of long leg (20-40mm), many legs (greater than 20 pin) is very common; Before welding; Need the welding foot of this type components and parts be inserted into printed wiring board (PCB) and go up in the corresponding installing hole, just can carry out follow-up welding job.Because the welding foot of this class component is longer, the rigidity of leg is poor, and under various internal stresss, external force effect, welding foot very easily produces deformation, and single in addition pin number is more, and in installation process, leg is difficult to aim at simultaneously the corresponding welding hole of installing, and causes the assembling difficulty.

Existing assembly method is will not have the leg of alignment receptacles to introduce one by one in the installing hole with tweezers, very time-consuming, the effort that operates, inefficiency.

Summary of the invention

In order to solve an above difficult problem, to raise the efficiency, the utility model proposes a kind of location comb of installing to the electronic devices and components of long leg, many legs.

The technical scheme of the utility model is following:

The electronic devices and components installing and locating comb that the utility model proposes comprises comb handle and broach, and the number of teeth of said broach is greater than the leg quantity of row's leg of the electronic devices and components that are mounted; Spacing a between the said broach equals the leg spacing of electronic devices and components; The end shape of said broach is unified to the left or to the right hook-shaped of level; Between broach, form L shaped comb groove; The entrance width b of L shaped comb groove is greater than the width of leg, and the bottom land height c of L shaped comb groove can easily import in the comb groove welding foot greater than the thickness of leg.

The locate mode of this location comb is following:

X, promptly locatees the directions X of welding foot by the A limit in the comb groove to: leg.

Y is between: the bottom land height c that utilizes the location comb is than leg thickness gapped (like 0.1mm); When 5～8 ° of location comb plane inclinations; In the horizontal direction; The gap does not just exist between location comb groove and the leg thickness, and the location comb just can be clamped in each leg in the groove, accomplishes welding foot Y direction location (as illustrating 2 with shown in Figure 3).

Because the spacing between the broach is corresponding consistent with the leg spacing, can adjust crooked leg from left and right directions like this, aim at the pad jack.Simultaneously, the end shape of said broach is unified to the left or to the right hook-shaped of level, can adjust the position all around of crooked leg so simultaneously, makes it aim at the pad hole.

Visible by technique scheme, the location comb of the utility model design is simple in structure, easy to operate; Can adjust the position of crooked leg simultaneously, make it aim at the pad hole, so just avoid transferring with pin ground of pin of tweezers; Can assemble fast, enhance productivity more than 5 times.

Description of drawings

Fig. 1 is the structural representation of location comb;

Fig. 2 is that leg imports the sketch map in the comb groove;

Fig. 3 is that the sketch map when passing through comb groove clamping leg is combed in the location.

Embodiment

Further specify the structure of the utility model below in conjunction with accompanying drawing:

Referring to Fig. 1, Fig. 2 and Fig. 3, the location comb includes comb handle 1 and broach 2, and the spacing a of broach 2 sets according to the spacing of the leg 4 of electronic devices and components, and is consistent with each other, and the quantity of broach will be wanted many one at least more than the quantity of leg.The end shape of broach is similar to hook; Hook is the unified outer to the left or to the right bending of level; Between broach, form L shaped comb groove 3, the entrance width b=leg width+0.15mm of L shaped comb groove, the bottom land height c=leg thickness e+0.10mm of L shaped comb groove; Since gapped between leg width, thickness and size b, the c, make leg can be easy to import in the comb groove.

When assembling, will locate the root importing of comb earlier from leg, the modification of this position leg is minimum, can easily leg be imported in the comb groove of location comb; The location comb slides to the 5-7mm place, tip position of leg down, and the sloped position comb is all clamped the leg in the groove again; Each leg that the location comb is clamped is aimed at its corresponding welded and installed hole, can leg be inserted in the welding hole.

Claims

1. the long pin electronic devices and components of leg more than kind installing and locating is combed, and it comprises comb handle and broach, it is characterized in that: the number of teeth of said broach is greater than the leg quantity of row's leg of the electronic devices and components that are mounted; Spacing a between the said broach equals the leg spacing of electronic devices and components; The end shape of said broach is unified to the left or to the right hook-shaped of level; Between broach, form L shaped comb groove; The entrance width b of L shaped comb groove is greater than the width of leg, and the bottom land height c of L shaped comb groove can easily import in the comb groove welding foot greater than the thickness of leg.

2. the long pin electronic devices and components of many legs according to claim 1 installing and locating comb is characterized in that said b=leg width+0.15mm, c=leg thickness+0.10mm.
