Abstract
The utility model discloses an electric joint waterproof sealer, wherein the sealer comprises a left-end locking nut, a reducing base, a sealing member, a reducing head and a right-end locking nutfrom left to right. When the lengths of the reducing base and the reducing head arenot so long, the sealer is assembled with the left-end locking nut, the reducing base, the sealing member, the reducing head and the right-end locking nut from left to right. The interiors of the reducing base and the reducing head are hollow cavities; the reducing base and the reducing head, the left-end locking nut and the reducing base as well as the reducing head and the right-end locking nut are respectively connected by threads; and the sealing member is positioned between the reducing base and the reducing head. Through the structure design of the reducing head and the reducing base, the technical problems of great difference of the volumes of a wiring harness and a joint and connection errors caused by shaking the wiring harness can be effectively solved. Through the combination of the reducing head and the reducing base, the cavity needed by the joint is formed,and the sealing of the cavity is completed so as to solve the problem of the waterproofing of the joint; and through the end sealing sheath of the reducing head and the reducing base and the locking nut, the sealing of the wiring harness and the end sealing of the cavity is solved.
Description
Technical field
The present invention relates to a kind of sealing device, relate in particular to a kind of sealer that electrical connector is played fixing and waterproof sealing function.
Background technology
Fast development and the range of application of industry, civil electrical product increasingly extensive; The adaptable environment for use condition of product has also been proposed increasingly high requirement; As by indoor to outdoor, conventional environment is to particular surroundings, the condition conversion of non-tight to sealing, high sealing etc.Existing market is badly in need of will only adapting to the multiple electrical connector of indoor use; As: network interface joint, video line joint, power lug etc. do one general, succinct, convenient; The protective treatment that cost performance is high again directly applies to outdoor or particular surroundings, and its degree of protection should be not less than IP66.
Existing such outdoor water-proof seal nipple product, not only structure is complicated, and cost is very high, and all is specificity, can not adapt to the demand of multiple joint, different environment for use conditions.
Summary of the invention
To the deficiency that existing market product practical application exists, the present invention provide a kind of simple in structure, with low cost, cost performance is high, reliability is high, the sealing of highly versatile, reinforce multipurpose joint waterproof sealing device.
Said sealer comprises left end locking nut, reducing seat, seal, reducing head and right-hand member locking nut from left to right.When reducing seat and reducing head length degree deficiency, said sealer is pressed left end locking nut, reducing seat, seal, adapter, seal, reducing head and the assembling of right-hand member locking nut from left to right.Said reducing seat, reducing head inside all are cavity.The reducing seat is respectively with the right-hand member locking nut with reducing seat, reducing head with reducing head, left end locking nut and is threaded.Left end locking nut and reducing seat, reducing head are respectively with the right-hand member locking nut that internal thread is connected or external screw thread connects; Seal is between reducing seat and reducing head.Through the structural design of reducing head and reducing seat, the volume great disparity difference, the wire harness that effectively solve wire harness and joint rock the technical problem that causes wiring faults.Through the combination of reducing head and reducing seat, constitute the required cavity of joint and accomplish the cavity sealing, solved the problem of joint waterproofing; Through the end sealing shroud and the locking nut of reducing head and reducing seat, the sealing of wire harness and the end sealing of cavity have been solved.Add and take over, can effectively expand the length and the width of reducing head and reducing seat, can hold the joint of particular length and width.
The turnover wire harness termination of reducing head, reducing seat can be single head, also can be double end or bull.During wiring; The space is limited often, and many different wire harness often need be together adjacent, if every wire harness disposes the waterproof sealing device separately; Occupation space is too big, and can be arranged in wire harness in the waterproof sealing device of band double end, bull reducing head and reducing seat this moment.In addition, during wiring, tend to run into the situation that circuit m road (m is more than or equal to 1) is divided into/synthesizes n road (n is more than or equal to 1), adopt single head, double end, bull structure, can guarantee the waterproof sealing of this type bifurcated line.
It is single head that the turnover wire harness termination of reducing head, reducing seat is at least, and turnover wire harness termination is that the above electrical connector waterproof sealing device locking nut position in the axial direction of double end is a coplane radially, or radially differs 1～2 level.
Double end or bull electrical connector waterproof sealing device locking nut position in the axial direction are coplanes radially, or radially differ 1～2 level.Radially during coplane, possibly cause difficult installation because of the steric requirements restriction, adopt locking nut radially to differ the waterproof sealing device of 1～2 level this moment, just can adapt to the installation of small space.
During use, choose overall dimension and cavity size suitable reducing head, reducing seat, add that seal combination gets final product.The reducer union outlet divides single head, double end, bull, and line outlet adds two ends locking nut screwing sealing with sealing shroud.When single seal nipple cavity length is not enough, can select supporting adapter lengthening for use.Said adapter is between reducing head, reducing seat; And said reducing head, reducing seat, adapter are that standard six square chi are very little, all can tighten with hand or spanner during use.
The present invention is particularly useful for the fixing and waterproof protective of video transmission product jointing under the outdoor mounted condition, can eliminate product and under outdoor severe environmental conditions, use the structure bad connection fault that very easily occurs, and guarantees the serviceability of product.
