the reinforcing sheet body deviates from one side of the bottom adhesive film is provided with a rectangular limiting boss, and the reinforcing sheet body faces one side of the bottom adhesive film and is provided with a plurality of L-shaped dispensing grooves.
Preferably, at least one side edge of the reinforcing sheet body is provided with a limiting outer edge part.
Preferably, four corner ends of the rectangular limiting boss are respectively provided with an R corner.
Preferably, the four corners of the reinforcing sheet body are respectively provided with a chamfer, and two sides of the extending wall of the limiting outer edge part are respectively provided with a chamfer.
Preferably, the protruding size of the rectangular limiting boss is 0.06 +/-0.01 mm.
Preferably, the depth of the L-shaped glue dispensing groove is 0.05 +/-0.02 mm.
The beneficial effects of the utility model are mainly embodied in that:
1. the positive and negative complementary shape design of the boss and the glue groove is adopted, the difficulty of double-sided etching is reduced, the requirement of node-free forming is met, and the circuit board cannot be damaged.
2. The flexible circuit board mounting and dismounting device can realize carrying limit and assembling limit, meets the requirements of loading position precision and matching precision, is particularly suitable for being used in a narrow space, and realizes auxiliary support and matching and fixing of the FPC flexible circuit board.

Detailed Description
The utility model provides a no node reinforcement piece for electronic product. The technical solution of the present invention will be described in detail below with reference to the accompanying drawings so as to be easier to understand and grasp.
A no node reinforcement piece for electronic product, as shown in fig. 1 to 4, including the mucosa at the bottom 1, and the main part 2 of the piece that bonds on the mucosa at the bottom 1, be equipped with in the main part of the piece and be a plurality of reinforcement piece vacancies 3 of matrix arrangement, be equipped with the reinforcement piece body 4 that bonds on the mucosa at the bottom 1 in arbitrary reinforcement piece vacancy 3, possess isolation gap 5 between the outline of reinforcement piece body 4 and the reinforcement piece vacancy, one side that reinforcement piece body 4 deviates from the mucosa at the bottom 1 is equipped with the spacing boss 6 of rectangle, one side that reinforcement piece body 4 moves towards the mucosa at the bottom 1 is equipped with a plurality of L type point and glues groove 7.
The specific implementation process and principle description are as follows:
this no node reinforcement piece is two-sided etching shaping, two-sided etching belongs to prior art, no longer gives details here, it needs to explain, at first carry out the outer contour part etching shaping of L type point glue groove 7 and reinforcement lamellar body 4 in L type point glue groove 7 one side in the present case, then carry out end mucosa 1 to L type point glue groove 7 one side and paste, carry out the periphery of the spacing boss 6 of rectangle at last and etch to make the outer contour of reinforcement lamellar body 4 pierce through, thereby form no node outer contour, reinforcement lamellar body 4 independently bonds on end mucosa 1. The double-sided etching is similar to the conventional double-sided etching process. The scheme adopts a positive and negative complementary shape design, so that the traditional double-sided etching process can be simplified.
When specifically using, the fixed demand of carrying on of reinforcement lamellar body is satisfied through L type point gluey groove 7, and the spacing boss 6 of rectangle does benefit to and carries out spacing cooperation with the joint end of FPC flexible line way board, designs fretwork groove or cushion cap at the joint end of FPC flexible line way board promptly to realize and spacing cooperation between the spacing boss 6 of rectangle, improved and carried stability, reduced the space demand.
In one embodiment, at least one side edge of the reinforcing sheet 4 is provided with a limiting outer edge 8.
Specifically, the reinforcing sheet 4 is disposed in a narrow space, and the reinforcing sheet 4 is easily displaced when being fixedly connected, so that the loading of other structural members is affected, and the reinforcing sheet 4 can be limited in position by the design of the limiting outer edge portion 8, and has a foolproof function, i.e., the position of the rectangular limiting boss 6 can be ensured by being carried in a fixed direction.
This embodiment can be optimized, and four angle ends of this spacing boss 8 of rectangle are equipped with the R angle respectively. It can provide certain ground cooperation tolerance, because the spacing boss 8 of rectangle belongs to little protruding structure, and the counterpoint requirement is higher during its cooperation, adopts the R angle design, can improve great ground tolerance, satisfies the butt joint demand.
In addition, four corners of the reinforcing sheet body are respectively provided with a chamfer, and two sides of the extension wall of the limiting outer edge part are respectively provided with a chamfer. The periphery of whole reinforcement lamellar body does not have the acute angle promptly, can prevent to produce the accidental injury condition to operating personnel and appear.
Finally, in the scheme, the protruding size of the rectangular limiting boss 6 is 0.06 +/-0.01 mm. The depth of the L-shaped dispensing groove 7 is 0.05 +/-0.02 mm. The requirement of narrow space of electronic products is met, the etching cost is low, and materials are saved.
Can discover through the above description, the utility model is used for the no node reinforcement piece of electronic product adopts the positive and negative reinforcement shape design in boss and gluey groove, has reduced the two-sided etching degree of difficulty, satisfies no node shaping demand, can not produce the damage to the circuit board. The flexible circuit board mounting and dismounting device can realize carrying limit and assembling limit, meets the requirements of loading position precision and matching precision, is particularly suitable for being used in a narrow space, and realizes auxiliary support and matching and fixing of the FPC flexible circuit board.
The above technical solutions of the present invention have been fully described, and it should be noted that the present invention is not limited by the above description, and all technical solutions formed by equivalent transformation or equivalent transformation adopted by the spirit of the present invention in the aspects of structure, method or function by those of ordinary skill in the art all fall within the protection scope of the present invention.
