Abstract
The utility model relates to an explosion-proof adapter for a cable with a rubber protective layer, and comprises a rubber bushing, a bushing core and the sealed heads at the two ends of the bushing; wherein a joint between the sealed heads and the bushing is a cylinder, the part from the outer flange of the bushing to the other end of the sealed heads is round platform-shaped. The inner wall of the part met by the sealed head and a cable is designed with orbicular seal rings in parallel. The inner diameter of the orbicular seal ring is smaller than the diameter of the cable. The utility model improves the waterproof performance, saves labor in connection and installation, and makes the laying of the cable smoother.
Description
The utility model relates to a kind of rubber cover Seal of Cables formula Explosion proof joint that is used for.
Junction in the rubber cover power cable laying task of down-hole, mine between cable; consideration for explosion-proof security; the traditional metal anti-explosion cable terminal box of general use; its structure is the embedded potted component of metal shell; need the termination of stube cable in box, to connect by binding post; this equipment heaviness is difficult for the cost height is installed.Also has the explosion-proof three-way connection of a kind of rubber cover cable (patent No.: 92219366.5 in addition; patentee: Liu Peili); it is made up of sleeve pipe, end socket and inner core; it is in " lotus root shape " inner core that cable embeds the cross section by the fixedly connected back of lead tieing; inner core is placed in the sleeve pipe, and the sleeve pipe two ends is fixed by end socket.End socket is fixed with the effective fluid sealant of cover.This Explosion proof joint also can be two logical forms.The Explosion proof joint of this form, the water-tight after the connection is not ideal enough, and its profile is not sufficiently oily, and is blocked easily in cable laying, produces inconvenience.
The purpose of this utility model is that a kind of waterproof sealing performance of design is good, lays the rubber cover cable Explosion proof joint of flexible structure easily.
A kind of Explosion proof joint of rubber cover cable, it comprises the end socket at sleeve pipe, the inner core in the sleeve pipe and the sleeve pipe two ends of elastomeric material, is characterized in: end socket and sleeve pipe junction are cylinder, the other end from the sleeve pipe outer rim to end socket is a truncated conical shape.
The Explosion proof joint of aforesaid rubber cover cable, end socket and cable contact, and parallel design has annular seal ring on the inwall of part, and the internal diameter of annular seal ring is little than cable size.
Owing to after the utility model adopted the ring-shaped continuous sealing ring, improved water resistance, and laborsaving convenience during connection, in addition, the tapered profile of joint makes laying of cable more smooth.
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing:
Fig. 1 is the structural representation of the utility model rubber cover cable Explosion proof joint connection status.
Fig. 2 is the structural representation of the connection status of three-way explosion-proof joint.
Fig. 3 is the structural representation of the rubber cover cable Explosion proof joint among the embodiment 3.
In the embodiment shown in fig. 1, inner core 3 has the groove that rhombus is not sealed in four cross sections, and cable 5 places in the groove respectively after being connected by terminal 6.Inner core 3 is placed in the sleeve pipe 2, and the two ends of sleeve pipe 2 are by end socket 1 sealing, and cable 5 passes from the endoporus of end socket 1.End socket 1 is a cylinder with sleeve pipe 2 connecting portions, is truncated conical shape from sleeve pipe 2 outer rims to end socket 1 other end and cable junction, with the design of cable connecting part inwall parallel annular seal ring 4 is arranged on the end socket, and the internal diameter of annular seal ring 4 is little than cable size.
In the embodiment shown in Figure 2, Explosion proof joint is a three-port structure, its inner core 3 is positioned at the person in charge 2.1 of sleeve pipe 2, the cable 5.1 that enters from sleeve pipe 2 arms 2.2 be responsible for the rhombus groove that is placed in after cable 5.2 in 2.1 is connected by terminal 6 on the inner core 3 in, do not hold at the person in charge of sleeve pipe and arm and all to be with end socket 1, with the design of cable connecting part inwall parallel annular seal ring 4 is arranged on the end socket 1, the internal diameter of annular seal ring 4 is little than cable size.Bigger on the person in charge, less on the arm, end socket 1 is a cylinder with the connecting portion of sleeve pipe 2, from sleeve pipe 2 outer rims to end socket 1 other end and the cable junction be truncated conical shape.
In the embodiment shown in fig. 3, inner core 3 has the groove that rhombus is not sealed in four cross sections, and cable 5 places in the groove respectively after being connected by terminal 6.Inner core 3 is placed in the sleeve pipe 2, and the two ends of sleeve pipe 2 are by end socket 1 sealing, and cable 5 passes from the endoporus of end socket 1.End socket 1 is a cylinder with sleeve pipe 2 connecting portions, is truncated conical shape from sleeve pipe 2 outer rims to end socket 1 other end with the cable junction, is provided with " O " RunddichtringO at cable 5 and sleeve pipe 2 contacts site.
