Abstract
The invention discloses a lock bolt of an O-shaped seal ring of a connector, which is composed of a screw and a nut and is characterized in that a self-locking surface is arranged at the lower end of the nut, and the self-locking angle theta of the self-locking surface is no less than the critical self-locking angle between the O-shaped seal ring and the lock bolt. In the invention, a self-locking principle is adopted, a self-locking surface and a transition angle are designed on the lock bolt of the O-shaped seal ring of the traditional connector, so that when the connector is assembled and used, the O-shaped seal ring can be limited to only have radial deformation and axial displacement within the design range, thus the deformation space of the O-shaped seal ring is enlarged, thereby avoiding breakage of the O-shaped seal ring caused by oversize axial pressure in assembly, and effectively improving the seal reliability of the connector.
Description
Technical field the present invention relates to a kind of improvement of connector O RunddichtringO lock-screw, takes this lock-screw, can avoid the O RunddichtringO when assembling mechanical damage to take place, and makes the sealing property of connector product more reliable.
Background technology is present, because O RunddichtringO sealing has also comparative maturity of good seal performance and design parameter, therefore seals with the O RunddichtringO and is widely used.Yet, be assembled to the O RunddichtringO on the connector or in the use at connector, the O RunddichtringO deforms under the external force effect that lock-screw produces and makes the O RunddichtringO fracture phenomena occur through regular meeting, has influenced the sealing reliability of connector.
Summary of the invention is in order to solve the deficiency that above-mentioned connector O RunddichtringO exists in assembling, the object of the present invention is to provide a kind of connector O RunddichtringO lock-screw, by optimal design to the connector locking screw, when product assembles and use, guarantee that the O RunddichtringO only carries out radial deformation and axial displacement in scope of design, increase the deformation space of O RunddichtringO, thus avoid sealing ring when assembling since the axial compressive force that the lock-screw that is subjected to is granted excessive appearance rupture.
The objective of the invention is to adopt following technical scheme to realize:
A kind of connector O RunddichtringO lock-screw, described lock-screw comprises screw rod and nut, it is characterized in that: the lower end of described nut is provided with from locking face, and should be from locking face should be not less than the critical of O RunddichtringO and lock-screw from locking angle θ from the locking angle.
Described critical definite by the coefficient of friction of lock-screw and O RunddichtringO from the locking angle, guarantee when moving to a certain degree that O RunddichtringO and lock-screw form from locking face at contact-making surface with assurance O RunddichtringO, the O RunddichtringO no longer is moved.
Describedly be equipped with excessive fillet from the bottom surface of locking face and nut and the junction of side.
The present invention uses self-lock mechanism, and design has from locking face and excessive angle on traditional connector O RunddichtringO lock-screw.When connector assembles and use, the O RunddichtringO under the effect of lock-screw external force, deform and its deformation plance and lock-screw form self-locking from locking face, guarantee that the O RunddichtringO only carries out radial deformation and axial displacement in scope of design, increased the deformation space of O RunddichtringO, thereby avoided the O RunddichtringO when assembling owing to the excessive phenomenon of rupture that occurs of the axial compressive force that is subjected to, effectively improved the sealing reliability of connector.
Description of drawings Fig. 1 is a lock-screw structural front view of the present invention;
Fig. 2 is that the present invention is used for connector O RunddichtringO assembling schematic diagram;
Fig. 3 is a locking screw mounting hole front view on the connector shell.
Description of reference numerals
1-connector shell 2-O RunddichtringO 3-lock-screw 31-screw rod 32-nut 4-is from the excessive fillet 8-of locking face 5-housing seal face 6-axial locating surface 7-locking screw 9-housing installing hole
Embodiment is further described the specific embodiment of the present invention below in conjunction with drawings and Examples:
Fig. 1 is lock-screw 3 structural front view of the present invention, and lock-screw 3 comprises screw rod 31 and nut 32, and the lower end of nut 32 is provided with from locking face 4, and this is not less than the critical from the locking angle of O RunddichtringO 2 and lock-screw 3 from locking face 4 from locking angle θ.For fear of when assembling, damaging O RunddichtringO 2, be equipped with excessive fillet 7 from locking face 4 and the bottom surface of nut 32 and the junction of side.
As shown in Figure 2, during connector shell 1 assembling, earlier O RunddichtringO 2 is inserted in the lock-screw 3, locking screw 8 on lock-screw 3 screw rods 31 sees through housing installing hole 9 in the interference mode then, axial locating surface 6 by housing seal face 5 and lock-screw 3 is realized the axial location of lock-screws 3, and O RunddichtringO 2 is completely fixed on the lock-screw 3.
In the assembling process that connector uses, the axial float distance L by lock-screw 3 guarantees connector, and the assembling of lock-screw 3 is smooth and easy in use, realizes locking with the mounting screw of butt end product; After the client finishes the product assembling, O RunddichtringO 2 is owing to be subjected to the axial compressive force of lock-screw 3, its carry out after the strain with nut 32 on form self-lockings from locking face 4, the housing installing hole 9 circumference formation faces contact at connector shell 1 no longer moves axially O RunddichtringO 2.Thereby not only realized carrying out face seal and radial seal at housing installing hole 9 places, after guaranteeing that the client finishes the product assembling, housing installing hole 9 parts at connector shell 1 have remarkable sealing property, and because O RunddichtringO 2 has enough deformation spaces, make O RunddichtringO 2 when assembling, mechanical damage can not take place, make the sealing property of product have better reliability.
