CN201527977U - Junction box of crystalline silicon solar cell component - Google Patents

Abstract

The utility model discloses a junction box of a crystalline silicon solar cell component, which comprises a box body and a box cover, wherein a plurality of clamping grooves is arranged on the upper end surface of the box body, a clamping hook matched with the clamping grooves is arranged on the box cover, the front surface of the clamping hook is provided with a raised clamping sign, and the raised clamping sign is right entirely exposed out of the clamping groove after the box cover is covered tightly. As the raised clamping sign is arranged on the clamping hook, and not until the raised clamping sign is right entirely exposed to the clamping groove, can the box cover be fastened, the judgment is simple, accurate, fast and convenient, and the phenomenon that the defective products generated due to the unfastened cover is avoided. The junction box has simple structure, practicability and low cost.

Description

A kind of crystal silicon solar battery component terminal box

Technical field

The utility model relates to a kind of crystal silicon solar battery component terminal box is installed.

Background technology

In the production of crystal silicon solar battery component, the installation terminal box is the indispensable operation during it is produced, and needs silica gel is stamped in the terminal box bottom, and bonds on the notacoria of the assembly back side, need lead-in wire is inserted the binding post chucking of terminal box after silica gel is cured, and cover tight lid.In the practical operation of carrying out the hamper lid, the workshop of battery component is generally directly pressed tight with hand, or the press device of simplicity of design.But the method for these two kinds of hamper lids, any not situation of tight lid of lid that all often occurs, owing to there is not any sign reminds people not cover tight lid, just carried out next step operation, cause terminal box not reach the purpose of dustproof and waterproof, cause the generation of bad product, bring massive losses for producer and user.

Summary of the invention

The utility model solves the above-mentioned problems in the prior art exactly, and a kind of crystal silicon solar battery component terminal box is provided, and uses this terminal box in crystal silicon solar battery component, makes people can judge very accurately whether lid has covered tightly.

For addressing the above problem, technical solution of the present utility model is: a kind of crystal silicon solar battery component terminal box, it comprises box body and lid, the box body upper surface is provided with a plurality of draw-in grooves, lid be provided with box body on the grab that is complementary of draw-in groove, the front of grab is provided with projection chucking sign, and after the lid lid was tight, the projection chucking sign on the grab was just in time all exposed draw-in groove.

Projection chucking on the above-mentioned described grab is designated the isosceles triangle of projection.

Because the utility model is provided with projection chucking sign on grab, have only projection chucking sign all to expose draw-in groove, indicate that just lid has covered tightly.So, in the process of hamper lid, no matter directly press tight with hand, perhaps the press device of simplicity of design is pushed, all expose draw-in groove as long as see the projection chucking sign on the grab, just represent lid by compressing, judgement is simple, accurate, quick, convenient, and having avoided has to cover the generation that does not tightly cause bad product because of lid.The utility model is simple in structure, practical, cost is low.

Description of drawings

Fig. 1 covers front view when tight fully for the utility model lid;

Fig. 2 covers vertical view when tight fully for the utility model lid;

Fig. 3 does not cover front view when tight fully for the utility model lid.

Embodiment

The utility model will be further described below in conjunction with accompanying drawing:

As Fig. 1, Fig. 2 and shown in Figure 3, present embodiment comprises box body 2 and lid 1, box body 2 upper surfaces are provided with a plurality of draw-in grooves 5, lid 2 be provided with box body 2 on the grab 4 that is complementary of draw-in groove 5, the front of grab 4 is provided with the isosceles triangle 3 of projection, after lid 1 lid was tight, the isosceles triangle 3 of the projection on the grab 4 just in time all exposed draw-in groove 5, position as shown in Figure 2.As shown in Figure 3, see the part of the isosceles triangle 3 of projection, what promptly see is isosceles trapezoid, and promptly Tu Qi isosceles triangle 3 is imperfect, proves that lid 1 and base 2 do not tighten fully.

Be appreciated that, the foregoing description of the present utility model combines concrete projection chucking sign, yet those skilled in the art can adopt difform projection chucking sign that the chucking of the projection in the foregoing description sign is replaced under general plotting of the present utility model, and finish corresponding function.

Claims (2)

1. crystal silicon solar battery component terminal box, it is characterized in that: it comprises box body (2) and lid (1), box body (2) upper surface is provided with a plurality of draw-in grooves (5), lid (2) be provided with box body (2) on the grab (4) that is complementary of draw-in groove (5), the front of grab (4) is provided with projection chucking sign, after lid (1) lid was tight, the projection chucking sign on the grab (4) was just in time all exposed draw-in groove (5).

2. crystal silicon solar battery component terminal box according to claim 1 is characterized in that: the projection chucking on the described grab (4) is designated the isosceles triangle (3) of projection.
