Description
Technical field
The utility model relates to mining field of connectors, especially a kind of mine explosion-suppression cable connector.
Background technology
The jockey of mine explosion-suppression cable connector is used for realizing by cable socket part, cable plug part and middle contact pin the electric power input of mining equipment.Existing mine explosion-suppression cable connector has the following disadvantages in making and using: 1, cable and pin connectors part need to realize insulation by the embedding insulating material when making, and it is complex operation not only, and the Embedding Material that adopts causes cost to increase; 2, be shaped with glue filling opening on the sidewall of the tubular shell of plug portion, Embedding Material solidifies rear and shell sticks together and can not split, and causes whole plugs and sockets part to reuse, and use cost increases.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of reasonable in design, simple in structure, easy to manufacture, insulation effect is good and the mine explosion-suppression cable connector that can reduce production costs.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of mine explosion-suppression cable connector, comprise socket, plug and contact pin, the coaxial installation of socket and plug, the two ends of contact pin are inserted into respectively in the Plug pin patch bay of socket and plug, plug is mainly by tubular shell, pin insulator and Plug pin patch bay consist of, pin insulator is coaxial to be inserted in the tubular shell, three Plug pin patch bay are installed on the pin insulator, it is characterized in that: the insulation back partition frame that is used for holding out against Plug pin patch bay of the coaxial plug-in mounting of tubular shell that is positioned at the pin insulator rear end, one of the coaxial plug-in mounting of tubular shell that is positioned at insulation back partition frame rear end is used for holding out against the metal partition pincers of insulation back partition frame, and the rear end that metal partition clamps is coaxial to arrange a cable enclasp device.
And described insulation back partition frame and metal partition pincers are all made vertically be used to the cable-through hole that installs cable.
And, a built-in axial metal guide pillar on the described pin insulator, the rear end of this metal guide pillar is connected with the front end of metal partition pincers, and a ground wire plug-in opening is made in the rear end of metal partition pincers.
And branch sleeve of the coaxial installation in described tubular shell rear end, the front end of this branch sleeve hold out against metal partition pincers, the coaxial installing cables enclasp device in the rear end of this branch sleeve.
Advantage of the present utility model and beneficial effect are:
1, pin insulator rear end successively coaxial installing insulating back partition frame, metal partition pincers and cable enclasp device in this connector, this structure has played the effect that compresses Plug pin patch bay, therefore during the mounting cable connector without encapsulating, not only saving of work and time, be convenient for changing, and can also reduce production costs.
2, since this connector in manufacture process without encapsulating, need not make glue filling opening on the sidewall of its tubular shell, so this cable connector can reuse not only, but also play the effect of saving use cost.
3, the boss height at pin insulator rear portion (being axial length) increases, and has guaranteed that Plug pin patch bay and cable joint part satisfies electric clearance and creepage distance requirement under the respective level to shell; Plug portion can connect use, satisfies mining field requirement.
4, the utility model be a kind of reasonable in design, simple in structure, manufacture easy, practical mine explosion-suppression cable connector, this connector improves insulator structure, therefore can be without the embedding insulating cement when mounting cable, its course of processing is time saving and energy saving, thereby has played the effect of enhancing productivity, reducing production costs.

Embodiment
The utility model is described in further detail below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection range of the present utility model with this.
A kind of mine explosion-suppression cable connector comprises socket 1, plug and contact pin 8, the coaxial installation of socket and plug, and the two ends of contact pin are inserted into respectively in the Plug pin patch bay of socket and plug.Because socket and contact pin belong to known technology, therefore no longer its structure is given unnecessary details with connection.Plug mainly is comprised of tubular shell 2, pin insulator 7 and Plug pin patch bay 5, and pin insulator is coaxial to be inserted in the tubular shell, three Plug pin patch bay of uniform installation on the pin insulator.
Innovative point of the present utility model is: the sidewall of tubular shell is closed structure, does not have glue filling opening on it.Be positioned at an insulation of the coaxial plug-in mounting of the tubular shell back partition frame 9 of pin insulator rear end, this insulation back partition frame is used for holding out against Plug pin patch bay, makes vertically a cable-through hole 12 that is used for installing cable on this insulation back partition frame.
Be positioned at metal partition pincers 10 of the coaxial plug-in mounting of tubular shell of the back partition frame rear end of insulating, these metal partition pincers are used for holding out against the insulation back partition frame, and these metal partition pincers are uniform vertically makes three for the cable-through holes 13 that install cable.
A built-in axial metal guide pillar 6 is the copper post in the present embodiment on the pin insulator, and the rear end of this metal guide pillar is connected with the front end of metal partition pincers, and a ground wire plug-in opening 11 that is used for the plug-in mounting ground wire is made in the rear end of metal partition pincers.
