Abstract
The utility model discloses a sealing device used for a sealable connector. The sealing device includes an elastic seal ring. A plastic framework used for fixing the elastic seal ring is arranged on an end face of the elastic seal ring. Injection holes used for connecting the elastic seal ring are arranged in the plastic framework. Bosses, which are spaced with the injection holes, are arranged on the plastic framework. Compared with the prior art, the sealing device used for the sealable connector has the following advantages: the sealing device is capable of realizing mechanical positioning of the seal ring by a connector sheath, preventing deformation, translocation and fall-off of the seal ring in a plug-in and plug-out process of the connector, and improving the airtightness and reliability between the seal ring and the connector.
Description
Technical field
The utility model relates to sealing device, is specifically related to a kind of sealing device for closed type connector.
Background technology
Vapour vehicle connector is mainly for realizing electrical connection or signal transmission, being mainly made up of socket jacket (material is plastics), socket (material is metal), plug boot (material is plastics), plug (material is metal).Connector is electrically connected or signal transmits inserting to be connected to realize by the assembly of socket jacket and socket and the assembly of plug boot and plug in use.Connector is by whether waterproof and dustproof can be divided into closed type connector and non-tight type connector.Wherein closed type connector can be realized waterproof and dustproof function because of it, is therefore applicable to automobile engine nacelle, chassis etc. to the higher position of connector waterproof and dustproof performance requirement.The difference of closed type connector and non-tight type connector is its waterproof and dustproof ability.Action principle is, at socket jacket and plug boot cooperation place, sealing ring (elastomeric material) is set, and at each line outlet of socket jacket and plug boot, seal plug (elastomeric material) is set.Sealing ring and seal plug and sheath and electric wire form interference fit, socket jacket and plug are expanded to internal cavities and outside isolated the opening after cover coordinates, make in cavity for being electrically connected or the socket of signal transmission and plug are not subject to the impact of outside atmosphere moisture content and dust.Seal plug is the interference fit of realization and sheath and electric wire after linking together mechanically with plug or socket in the prior art, therefore reliable operation.And sealing ring is by being connected inserting with plug boot (or socket jacket) after the assembling of interference mode and socket jacket (or plug boot) again, in plug process sealing ring yielding, be shifted, come off, can cause seal failure.
Utility model content
Sealing ring for closed type connector in prior art is yielding in plug process, be shifted, come off, thereby causes the technical problem of seal failure, and the utility model provides a kind of sealing device for closed type connector, realizes the reliable connection of sealing ring.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of sealing device for closed type connector, it comprises elastic seal ring, on an end face of described elastic seal ring, be provided with the plastic skeleton for fixing elastic seal ring, on described plastic skeleton, be provided with the injecting hole for being connected with elastic seal ring, on plastic skeleton, be arranged at intervals with boss with injecting hole.
For realizing being uniformly distributed of injection molding material between elastic seal ring and plastic skeleton, and meet the stress equalization between boss and hole clipping, described boss and injecting hole interval also evenly arrange.
Compared with prior art, the utility model has following advantage: can realize the machinery location of connector protective sleeve to sealing ring, prevent sealed ring deformation, transposition in connector plugging process, come off, improve sealing and reliability between sealing ring and connector.

Fig. 2 is the structural representation of the utility model plastic skeleton and sealing ring combination.
Fig. 3 is the profile of Fig. 2 along center line.
Fig. 4 is the structural representation of the utility model plastic skeleton and sealing ring and connector protective sleeve assembling.
Embodiment
As shown in Figure 1, Figure 2 and Figure 3, the present embodiment is for the sealing device of closed type connector, it comprises elastic seal ring 2, on an end face of described elastic seal ring, be provided with the plastic skeleton 1 for fixing elastic seal ring, on described plastic skeleton, be provided with the injecting hole 4 for being connected with elastic seal ring, on plastic skeleton, be arranged at intervals with boss 6 with injecting hole.
Preferably for realizing being uniformly distributed of injection molding material between elastic seal ring and plastic skeleton, and meet the stress equalization between boss and hole clipping as of the present utility model, described boss and injecting hole interval are also uniformly distributed setting.
Manufacture method of the present utility model is: first, use injection moulding process to produce plastic skeleton, then plastic skeleton is put into injection mold and carry out the production of sealing ring, the elastomeric material of sealing ring this when body formed elastomeric material inject injecting hole and connect as one with plastic skeleton, the injecting hole designing on plastic skeleton is with the reliable connection of guarantee skeleton and sealing ring elastomeric material body.
Using method of the present utility model is: as shown in Figure 4, on connector protective sleeve 3, the position corresponding with boss is provided with hole clipping 5, fasten and realize being fixedly connected with between plastic skeleton and connector protective sleeve by boss and hole clipping, thereby realize being fixedly connected with between elastic seal ring and connector protective sleeve.
Claims (2)
1. the sealing device for closed type connector, it is characterized in that: it comprises elastic seal ring (2), on an end face of described elastic seal ring, be provided with the plastic skeleton (1) for fixing elastic seal ring, on described plastic skeleton, be provided with the injecting hole (4) for being connected with elastic seal ring, on plastic skeleton, be arranged at intervals with boss (6) with injecting hole.
2. the sealing device for closed type connector according to claim 1, is characterized in that: described boss and injecting hole interval also evenly arrange.
