The utility model relates to a kind of electronic building bricks, and in particular to a kind of connector water-proof rubber piece, and for forming The particular manufacturing craft of the rubber parts.

Background technique

Existing general connector water-proof rubber piece, primary structure is as depicted in figs. 1 and 2, has the vertical cloth of one The pars contractilis 1 set has at the edge of pars contractilis 1 for installing the horizontally disposed end face 2 combined.Its shape side is for guiding And appearance considers, there is chamfer design.The design of above-mentioned shape side in die molding process, leading to die workpiece, there are wedge angles Phenomenon, as shown in Figure 3 and Figure 4, for forming the first type face 11 of pars contractilis and for forming end face on water-proof rubber piece mold The position on shape side of 12 junction of second type face will form wedge angle（Acute angle）, the structure of these wedge angles is on the one hand in manufacture mould It is big that difficulty is formed during tool, is easily damaged in bruting process, is influenced yield.On the other hand it is molded in high speed quantity-produced And ejection（Demoulding）In the process, these acute angles are easy to influence the quality conformance and mold of product by rubber parts attrition Service life.

Designer is based on being engaged in such product design manufacture practical experience and professional knowledge abundant for many years, and cooperates scientific principle Utilization, be actively subject to research and innovation, the structure of connector water-proof rubber piece improved, while improving corresponding molding Mold, to improve die life, Improving The Quality of Products.By constantly studying, designing, and sample and improvement are studied repeatedly Afterwards, the utility model having practical value is created finally.

Summary of the invention

Goal of the invention：In order to overcome the deficiencies in the prior art, the utility model provides a kind of connector waterproof Rubber parts.

Technical solution：In order to solve the above technical problems, connector water-proof rubber piece provided by the utility model, has one The pars contractilis of body, the edge of the pars contractilis have for installing the end face combined, have between the end face and pars contractilis flat Face structure.

Specifically, the height of the planar structure is 0.15mm ~ 0.3mm, and seal rubber part shape makes a variation not under this shape Greatly, it will not influence the integral sealing of connector, and Male/female connector changes less slotting force value.

Specifically, the pars contractilis has bellows-like structure.

Specifically, the end face and planar structure are perpendicular.

The utility model provides particular manufacturing craft for forming above-mentioned connector water-proof rubber piece simultaneously, including be used at First type face of type pars contractilis, the second type face for forming end face and the third type face for molding flat structure, it is described The both ends in third type face are connect with the first type face and second type face respectively.

Specifically, the height in third type face is 0.15mm ~ 0.3mm.

Specifically, third type face and second type face are perpendicular.

Using the improved product structure of the utility model, planar structure, plane are increased newly in the outer edge of water-proof rubber piece Size is about 0.15mm ~ 0.3mm, and the variation of seal rubber part shape less, will not influence the integral sealing of connector under this shape, And Male/female connector changes less slotting force value.And the original wedge angle of intermediate location is modified to prosposition by corresponding mould structure, In terms of mold production, the mold production stability that can significantly improve.

Beneficial effect：The utility model optimizes rubber parts local shape under the premise of not influencing on properties of product, reduces The angular shape of rubber mold shaping workpiece reaches and improves die life, the effect of Improving The Quality of Products.

Specific embodiment

The general connector of the present embodiment with water-proof rubber piece referring to figs. 5 and 6 shown in, there is arranging vertically for one Pars contractilis 1 has for installing the horizontally disposed end face 2 combined at the edge of pars contractilis 1, has between end face 2 and pars contractilis 1 There is vertical planar structure 3.The height of the planar structure is 0.15mm ~ 0.3mm, this shape/thickness is to seal rubber part shape Variation less, will not influence the integral sealing of connector, and Male/female connector is in tolerance interval the variation of slotting force value.It stretches The outer profile bellows-like structure in contracting portion 1, it is ensured that connector installation and and using when in occur in various modifications are still able to maintain The sealing in portion, end face 2 are used for Matching installation surface, the same Contact Seal ring of action principle.Planar structure 3 and end face 2 with it is perpendicular,

Particular manufacturing craft for forming above-mentioned connector water-proof rubber piece is as shown in Figure 7 and Figure 8 including sequentially connected First type face 11, third type face 13 and second type face 12, wherein the first type face 11 is used for forming pars contractilis 1, second type face 12 In molding end face 2, third type face 13 is used for molding flat structure 3, and third type face 13 is mutually perpendicular to second type face 12.Meet and adds The convenience and demoulding/ejection lower resistance of work.

The revealed dilatation structure for connecing device water-proof rubber piece and using corrugated tube shape of the present embodiment, it is preferred that emphasis is end Face（Faying face is installed）With the plane Transition Design of deformation position, the elastic water-proof sealing of connector is realized in this field, More implementation patterns can be presented in pars contractilis, and at this, then it will not go into details.

The utility model provides a kind of mentality of designing and method for connecing device water-proof rubber piece, implements the technical side There are many method and approach of case, and the above is only the preferred embodiment of the utility model, it is noted that this technology is led For the those of ordinary skill in domain, without departing from the principle of this utility model, several improvements and modifications can also be made, These improvements and modifications also should be regarded as the protection scope of the utility model.Each component part being not known in the present embodiment is available The prior art is realized.
