US12276489 - Detonator connector having leg wire locking structure
The patent describes a detonator connector featuring a leg wire locking structure that enhances connection stability and reliability by securely fixing the position of leg wires or bus wires within a casing. It includes an upper and lower casing with an elastic locking panel that allows for easy manipulation while ensuring that the leg wire remains properly positioned during use.
Claim 1
- A detonator connector having a leg wire locking structure, the detonator connector comprising: a wiring bracket member made of a conductive material and formed with a plurality of wire fitting grooves into which a leg wire of a detonator or a bus wire is inserted; a lower casing member on which the wiring bracket member is positioned; an upper casing member for covering an upper part of the lower casing member; a casing locking part for fixing a position of the upper casing member is provided on front sides of the lower casing member and the upper casing member, wherein a leg wire position locking part for catching and fixing a position of the leg wire or the bus wire is positioned in an inside of the lower casing member, wherein the inside of the lower casing member further comprises a casing locking space part, wherein the casing locking part comprises: an elastic locking panel part elastically bent in forward and backward directions, provided with first locking catch jaws protruding from lower end sides thereof, and positioned on the front side of the upper casing member so as to be inserted into the casing locking space part, wherein the elastic locking panel part is provided with an unlocking handle part protruding from a front side thereof and enabling an operator to pull or push the elastic locking panel part by hand manipulation, wherein a first leg wire entrance positioned on the front side of the lower casing member and through which the leg wire passes is formed in a shape open to an upper side, and the unlocking handle part is provided with a locking stopper protrusion part protruding to be inserted into the first leg wire entrance at a front and allowing both sides thereof to be supported on inner surfaces of the first leg wire entrance, so as to guide forward and backward movement of the elastic locking panel part and restrict leftward and rightward movement of the elastic locking panel part. a wiring bracket member made of a conductive material and formed with a plurality of wire fitting grooves into which a leg wire of a detonator or a bus wire is inserted; a lower casing member on which the wiring bracket member is positioned; an upper casing member for covering an upper part of the lower casing member; a casing locking part for fixing a position of the upper casing member is provided on front sides of the lower casing member and the upper casing member, wherein a leg wire position locking part for catching and fixing a position of the leg wire or the bus wire is positioned in an inside of the lower casing member, wherein the inside of the lower casing member further comprises a casing locking space part, wherein the casing locking part comprises: an elastic locking panel part elastically bent in forward and backward directions, provided with first locking catch jaws protruding from lower end sides thereof, and positioned on the front side of the upper casing member so as to be inserted into the casing locking space part, an elastic locking panel part elastically bent in forward and backward directions, provided with first locking catch jaws protruding from lower end sides thereof, and positioned on the front side of the upper casing member so as to be inserted into the casing locking space part, wherein the elastic locking panel part is provided with an unlocking handle part protruding from a front side thereof and enabling an operator to pull or push the elastic locking panel part by hand manipulation, wherein a first leg wire entrance positioned on the front side of the lower casing member and through which the leg wire passes is formed in a shape open to an upper side, and the unlocking handle part is provided with a locking stopper protrusion part protruding to be inserted into the first leg wire entrance at a front and allowing both sides thereof to be supported on inner surfaces of the first leg wire entrance, so as to guide forward and backward movement of the elastic locking panel part and restrict leftward and rightward movement of the elastic locking panel part.
