Abstract

The utility model relates to the printed circuit board (PCB) industry, in particular to telescopic electricity shielding edgings which comprise a first steel plate (1) and a second steel plate (2). A fixture clamping point (5) is arranged at one end of the first steel plate (1), holes (4) are arranged on two sides of the first steel plate (1) in the length direction, sliding chutes (3) corresponding to the holes (4) are arranged on two sides of the second steel plate (2) in the length direction, the first steel plate (1) and the second steel plate (2) are connected by a screwing component (6) through the holes (4) and the sliding chutes (3) and move along the direction of the sliding chutes (3) through adjustment of the screwing component (6), and therefore, the whole length is adjusted. The electricity shielding edgings have the advantages that operation is simple, cost is low, length of the electricity shielding edgings can be adjusted freely according to length of a PCB, the electricity shielding edgings can be recycled, and materials can be saved.

Description

The electric edge strip of a kind of telescopic retaining

Technical field

The utility model relates to the printed electronic circuit board industry, is specifically related to the electric edge strip of a kind of telescopic retaining that uses in a kind of printed circuit board electroplating process.

Background technology

In printed electronic circuit board industry electroplating process, can use the retaining electricity edge strip of different size; Specifically need decide according to the physical length of wiring board, the main purpose of keeping off electric edge strip is " fringing effect " that prevents in the electroplating process, and the plank copper facing of avoiding flying clinging to both sides is thick partially or uneven; And general PCB producer adopts double face copper to carry out cutting to make the electric edge strip of retaining in the prior art; Its thickness general requirement is greater than 1.0mm, and length then needs to be processed into the size that different size requires according to the length of wiring board, and not only usage quantity is very big for the retaining electricity edge strip of this routine; And its length specification is more; Access times are limited, the cost waste more greatly, also is unfavorable for environmental protection, and the thickness of the electric edge strip of this conventional retaining also can receive certain restriction, approaches excessively like thickness and is prone to bending; And the blocked up problem such as can occur being prone to come off of thickness can not play effects such as good protection and support.

The utility model content

In order to solve the problem of above-mentioned proposition, this practicality is adopted provides a kind of length, electric edge strip of reusable scalable retaining that can come to adjust arbitrarily the electric edge strip of retaining according to the length of plank, uses following technical scheme:

The electric edge strip of a kind of telescopic retaining; Comprise first steel plate and second steel plate; Said first steel plate, one end is provided with anchor clamps folder point; Wherein be provided with the hole along the said first steel plate length direction both sides, be provided with and the corresponding chute in hole along the said second steel plate length direction, two sides, the parts of screwing are connected first steel plate through hole, chute with second steel plate.

Preferably, the equal diameters of the width of said chute and the said parts of screwing.

Preferably, said hole is a screw hole, and quantity is individual, is square or rectangular and arranges.

Preferably, the said parts of screwing are screw or screw, and quantity is 4, matches with the hole.

Preferably, said chute quantity is bar, is arranged parallel to each other.

Preferably, the material of said first steel plate and second steel plate is 316 or 304 stainless steels, and thickness is 1mm.

The utlity model has following beneficial effect:

1, has easy to operately, can come the length of the electric edge strip of adjustment retaining arbitrarily according to the length of wiring board;

2, cost low, reusable, and can economical with materials.

Description of drawings

Fig. 1 is the plat of the utility model;

Fig. 2 is the stereographic map of the utility model.

The practical implementation instance

To combine accompanying drawing and embodiment to come the utility model is done further detailed explanation below.

Embodiment:

Embodiment:

With reference to Fig. 1, shown in Figure 2; The utility model provides a kind of telescopic retaining electric edge strip; Comprise that first steel plate 1 and second steel plate, 2, the first steel plates, 1 one ends are provided with anchor clamps folder point 5, are provided with hole 4 along first steel plate, 1 length direction both sides; Be provided with and hole 4 corresponding chutes 3 along second steel plate, 2 length directions, two sides, the parts 6 of screwing are connected first steel plate 1 through hole 4, chute 3 with second steel plate 2.The material of first steel plate 1 and second steel plate 2 is 316 or 304 stainless steels, and thickness is 1mm; Hole 4 is a screw hole, and quantity is 4, is square or rectangular and arranges; The parts 6 of screwing are screw or screw, and quantity is 4, matches with hole 4; Chute (3) quantity is 2, is arranged parallel to each other.

Realize through following operation that specifically 4 parts 6 of screwing screw in chutes 3 through 4 holes 4, and first steel plate 1 is connected with second steel plate 2; Through the adjustment parts 6 of screwing; Can reach first steel plate 1 or second steel plate 2 are moved along groove 3 directions, thereby reach the total length of regulating first steel plate 1 and second steel plate 2, thereby satisfy the processing request of the wiring board of different lengths; In order to make the parts 6 of screwing to screw in chute 3, the width of chute 3 and the equal diameters of screwing parts 6 are set.

First steel plate 1 of the utility model and the length of second steel plate 2 can be decided according to wiring board dimensions or equipment making ability, and as the length of two steel plates is all processed 15 inches, the length of chute is processed about 14 inches; Then this combination just can be adjusted its length arbitrarily between 16～28 inches, and existing is that example is explained its concrete implementation procedure with 20 inches specifications of plank length, when flying after crust overworks wiring board; The electric edge strip of retaining is drawn close a plate at edge; Fly to cling to the anchor clamps folder point 5 of an end of clamp A steel plate, unclamp the parts 61,62,63,64 of screwing, first steel plate 1 or second steel plate 2 can be free to slide along chute 3; It is 10 inches that adjustment makes first steel plate 1, second steel plate, 22 coincidence zones; Even its total length is 20 inches, the parts 61,62,63,64 of will screwing are at last screwed complete operation.

The foregoing description is the utility model preferred implementation; But the embodiment of the utility model is not restricted to the described embodiments; The inflation method of other different size specification circuit card is so similar; And other any do not deviate from change, the modification done under spirit and the principle of the utility model, substitutes, combination, simplify, and all should be the substitute mode of equivalence, is included within the protection domain of the utility model.
