Abstract
The utility model relates to a step-type sealed cable connector, belonging to the field of communication equipment. The connector comprises a sealing ring, a connecting nut and a joint, wherein the inner wall of the connecting nut is equipped with a step-shaped groove, the sealing ring is arranged on the inner wall of the connecting nut, and the sealing ring is matched with the step-shaped groove of the connecting nut; and the joint is connected with the connecting nut. According to the step-type sealed cable connector, the step is added to the sealing ring so that the sealing ring can be located, and the sealing ring has good sealing effect due to double pressures of the connecting nut and a cable; and a thermal shrinkable sleeve tube is omitted, so that installation is very convenient.
Description
Technical field
The invention belongs to domain of communication equipment, be specifically related to a kind of steps type seal cable connector.
Background technology
Now, connector has a wide range of applications at communication field, and the existing a super gentle 1/2 helical form cable connector that is applied to communication field was introduced China by U.S. Andrew before 10 years.This cable connector, so far still also using, shortcoming is that in use sealing ring can be moved, between the crust of cable and attaching nut, exist gap can not well play sealing function, and this cable connector has a heat-shrinkable T bush, must carry hair dryer heat-shrinkable T bush is shunk and installs, install very trouble.
Summary of the invention
The invention provides a kind of steps type seal cable connector, having increased step on sealing ring makes sealing ring to locate, thereby the dual-pressure that makes sealing ring be subject to attaching nut and cable plays sealing function, saved heat-shrinkable T bush simultaneously, make install very convenient.
Technical solution of the present invention is as follows:
A kind of steps type seal cable connector, is characterized in that, comprises sealing ring, attaching nut and joint; Described attaching nut's inwall is provided with a circle step groove, and described sealing ring is arranged on attaching nut's inwall, and sealing ring and attaching nut's step groove is suitable; Described joint is connected with the attaching nut.
Described steps type seal cable connector further designs and is, sealing ring lower surface and attaching nut's step groove is suitable, and the sealing ring upper surface is connected with cable sheath.
Described steps type seal cable connector further designs and is, the cross section of sealing ring is the step bulge-structure.
Described steps type seal cable connector further design is, sealing ring employing silicon rubber material.
beneficial effect of the present invention:
1. steps type seal cable connector of the present invention, has increased step and make sealing ring to locate on sealing ring, thereby the dual-pressure that makes sealing ring be subject to attaching nut and cable plays sealing function, good airproof performance.
2. the present invention has saved heat-shrinkable T bush simultaneously, make install very convenient.
The accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram that steps type seal cable connector of the present invention is connected with cable.
Fig. 2 is the ring structure schematic diagram.
The structural scheme of mechanism that Fig. 3 is joint.
In figure: the 1-sealing ring; 11-sealing ring upper surface; 12-sealing ring lower surface; 2-attaching nut; 21-step groove; The 3-cable sheath; The 4-joint.
Embodiment
As illustrated in fig. 1 and 2, steps type seal cable connector of the present invention, comprise sealing ring 1, attaching nut 2 and joint 4; Attaching nut 2 inwall is provided with a circle step groove 21, and described sealing ring 1 is arranged on attaching nut 2 inwall, and sealing ring 1 is suitable with attaching nut 2 step groove 21; Described joint 4 is connected with attaching nut 2.Described sealing ring lower surface 12 is suitable with attaching nut 2 step groove 21, and sealing ring upper surface 11 is connected with cable sheath 3.
As shown in Figure 3, be the structural representation of joint 4, joint 4 links together with attaching nut 2, during connection, joint 4 and attaching nut's 2 use spanners is wrenched.
Sealing ring 1 of the present invention, be arranged to the step bulge-structure, when connecting, sealing ring upper surface 11 closely is connected with cable sheath 3, sealing ring lower surface 12 is suitable with attaching nut 2 step groove 21, closely connects, and sealing ring 1 has been subject to from cable sheath 3 and attaching nut's 2 left and right and upper and lower pressure, make the sealing property of sealing ring 1 greatly promote, make cable very tight with being connected of connector.
Steps type seal connector of the present invention, increased step and make sealing ring 1 to locate on sealing ring 1, thereby the dual-pressure that makes sealing ring 1 be subject to attaching nut 2 and cable plays sealing function, good airproof performance, the present invention has saved heat-shrinkable T bush simultaneously, make install very convenient.
