Abstract
The invention discloses a manufacturing process for a sealing structure of an electric junction box. The manufacturing process for the sealing structure of the electric junction box comprises the steps that colloidal organic rubber and rubber curing accelerators are mixed and then put in a sealing groove of the electric junction box; (2) the electric junction box is heated and keeps at a constant temperature of 180+/-10 DEG C for 8+/-1 minutes; (3) the electric junction box is cooled. The manufacturing process for the sealing structure of the electric junction box can be applied to an waterproof and dustproof outer shell with the protection level of IP68, and is resistant to tearing, the explosion proof criteria requires that a sealing ring can not be taken out of the sealing groove, and the sealing ring is resistant to extremely high and extremely low temperatures (-60+180 DEG C), is much better than any other sealing ring on the aspect of materials, and has good pressing performance. The hardness of silica gel can be lowered to 20 shore A, is good in elasticity and is flattened after being compressed.
Description
Technical field
The present invention relates to a kind of manufacturing process of hermetically-sealed construction, specifically, relate to a kind of manufacturing process of hermetically-sealed construction of electric connection box.
Background technology
At present, known electrical terminal block is widely used in electronic equipment, because wire is through spool.And just adopt terminal box as excessive use at the joint area of wire (such as circuit is long, or spool wants corner), and spool is connected with terminal box, and the wire of spool the inside is linking up in terminal box, and it plays protection and the effect being connected to wire.
Current electric connection box comprises upper cartridge body and lower box body mostly, and the position that lower box body is connected with upper cartridge body arranges rubber seal and seals, to prevent liquid and dust and other antiknock device requirements.
The following several method of current existence:
1, flexible sealing ring, by elastic body moulding moulding, its material is natural rubber, acrylonitrile-butadiene rubber, silica gel etc., this sealing ring is successively opened, material that can be used according to sealing ring, adjust its hardness, then, by sealing ring indentation sealing groove, its shortcoming is: can without difficulty sealing ring be taken out or be dropped out.
2, the material compression molding of flexible artificial rubber line employing and above-mentioned or elastomer foam, it is cut Len req, is then pressed in seal groove, and its shortcoming is: can without difficulty sealing ring be taken out or be dropped out.Further, the boundary at this sealing ring two ends disconnects, and this may cause leaking, and maybe will force sealing ring two ends to be bonded together.
3, flexible sealing ring, passes through die cut by artificial rubber sheet or artificial rubber foam, forms the same shape of seal groove of placing with them.Sealing ring is continual, and its shortcoming is: can without difficulty sealing ring be taken out or be dropped out.
Summary of the invention
The present invention has overcome shortcoming of the prior art, a kind of manufacturing process of hermetically-sealed construction of electric connection box is provided, can be used for waterproof and the dust cover of degree of protection IP68, and sealing ring has been not disconnect, in some level of protections, the packing ring of disconnection is unallowed.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:
A manufacturing process for the hermetically-sealed construction of electric connection box, is characterized in that, comprises the following steps:
1), by gluey organic rubber, after Cure of Rubber promoter is mixed, put into the seal groove of electric connection box;
2) electric connection box is heated;
3) cooling.
Further, the temperature of described heating is 180 ± 10 ℃ of constant temperature, 8 ± 1 minutes time.
Further, in the mixture of gluey organic rubber and Cure of Rubber promoter, also added toner.
Further, the mass percent of described organic rubber is 95-99%, and the mass percent of described Cure of Rubber promoter is 0.5-2.5%, and the mass percent of described toner is 0.5-2.5%.
Further, the mass percent of described organic rubber is 99%, and the mass percent of described Cure of Rubber promoter is 0.5, and the mass percent of described toner is 0.5%.
Further, the vulcanizer that described electric connection box is put into preheating heats.
Compared with prior art, the invention has the beneficial effects as follows:
The manufacturing process of the hermetically-sealed construction of a kind of electric connection box of the present invention, can be used for waterproof and the dust cover of degree of protection IP68, anti-tearing can not be taken out sealing ring from seal groove, this is that explosion-proof criteria is desired, in addition sealing ring can be resistance to very high and low-down temperature (60+180 ℃, more much better than other any sealing ring materials, and there is good compression, because silica gel hardness is adjustable down to 20shore A, extraordinary elasticity, after compression, silica gel flattens.
Accompanying drawing explanation
Accompanying drawing is used to provide a further understanding of the present invention, for explaining the present invention, is not construed as limiting the invention together with embodiments of the present invention, in the accompanying drawings:
Fig. 1 is the schematic diagram of the hermetically-sealed construction of a kind of electric connection box of the present invention.
1---electric connection box; 2---seal groove;
