Abstract

A detonator connector having a wire protection structure is proposed. The detonator connector includes a wiring bracket member made of a conductive material and provided with a plurality of wire fitting grooves into which a plurality of wires connecting a detonator and a blasting machine to each other is inserted, a lower casing member on which the wiring bracket member is positioned, and an upper casing member configured to cover an upper part of the lower casing member, wherein wire end insertion parts into which end sides of the wires are inserted are provided in an inside of the lower casing member, thereby greatly improving convenience in the work of connecting a blasting machine and a detonator to each other with the wire and reducing working time.

First claim

The invention claimed is:

1 . A detonator connector having a wire protection structure, the detonator connector comprising:
a wiring bracket member made of a conductive material and provided with a plurality of wire fitting grooves into which a plurality of wires are inserted; a lower casing member on which the wiring bracket member is positioned; and an upper casing member configured to cover an upper part of the lower casing member, wherein wire end insertion parts into which end sides of the wires are inserted are provided in an inside of the lower casing member, wherein the wire end insertion parts are positioned to enable vertically folded or vertically bent ends of the wires fitted to the wire fitting grooves of the wiring bracket member to be inserted, and the vertically folded or vertically bent ends side of the wire positioned inside of the lower casing member, wherein each wire end insertion part comprises: a wire protection partition wall part for surrounding a space in which the ends of the wires are inserted, wherein a first wire is fitted to any one side of the plurality of wire fitting grooves, and a second wire is fitted to another side of the plurality of wire fitting grooves, thereby wiring the first wire and the second wire to each other, and at least any one end of the first wire and the second wire is inserted into the wire end insertion parts.

2 . The detonator connector of claim 1 , wherein a plurality of side through holes through which the respective wires pass is positioned in both side parts of the lower casing member, and
an inner space of each wire end insertion part is divided by a space partition wall part, so as to be formed into a plurality of spaces corresponding to the plurality of side through holes.

3 . The detonator connector of claim 1 , wherein the wire protection partition wall part is formed with the insertion space having a size allowing a clearance space to be formed around an outer circumference of the end of each wire.

4 . The detonator connector of claim 1 , wherein the wire end insertion parts are positioned between respective side parts of the lower casing member and the wiring bracket member, and
the wire protection partition wall part comprises: a first wire protection partition wall positioned between a side part of the lower casing member and the wiring bracket member; and a pair of second wire protection partition walls having both ends thereof fixed to the side part and the first wire protection partition wall and spaced apart from each other, so as to form the space enabling the end of each wire to be inserted therein.

5 . The detonator connector of claim 4 , wherein the first wire protection partition wall is provided with a wire seating groove part on which each wire is seated.

6 . The detonator connector of claim 1 , further comprising:
a wire protection lubrication member positioned inside the wire end insertion parts to form an oil film by surrounding the end of each wire.

7 . The detonator connector of claim 6 , further comprising:
a terminal protection lubrication member for forming an oil film by surrounding an outer surface of the wiring bracket member.

8 . The detonator connector of claim 7 , wherein the wire protection lubrication member and the terminal protection lubrication member are grease.

9 . The detonator connector of claim 1 , wherein each wire comprises:
the first wire inserted into the inside of the lower casing member through a front wire entrance of the lower casing member; and the second wire inserted into the inside of the lower casing member by passing through a side part of the lower casing member, the wiring bracket member comprises: a first wire connection bracket part positioned to be spaced apart from any one side part of the lower casing member and to which any one of a positive pole (+) wire and a negative pole (−) wire of the second wire is fitted and connected; a second wire connection bracket part formed by being folded at a first end side of the first wire connection bracket part and to which any one of a positive pole (+) wire and a negative pole (−) wire of the first wire is fitted and connected; a third wire connection bracket part positioned to be spaced apart from the other side part of the lower casing member and to which the other of the positive pole (+) wire and the negative pole (−) wire of the second wire is fitted and connected; and a fourth wire connection bracket part formed by being bent at a second end side of the third bracket part and to which the other of the positive pole (+) wire and the negative pole (−) wire of the first wire is fitted and connected, and the respective wire end insertion parts are positioned between any one side part of both side parts of the lower casing member and the first wire connection bracket part, and between the other side part of the lower casing member and the third wire connection bracket part.
