Description

The present invention relates to a branch connector for underline connection.

This is related to the improvement of the underline connecting equipment for which the applicant has obtained a patent right, and the underline connecting equipment must be stripped of the insulation of the underline when branching the underline to the main line. If the main line is larger than the applicable size that the underline connecting equipment can handle, there is a problem that the main line is limited in size because there is a risk that the main line may be laterally shifted during tightening. .
Japanese Patent No. 2909060

The present invention has been made in order to solve the problems described in the background art, and it is possible to connect the underline connecting branch connector that can be connected without peeling off the underline insulation coating and can expand the applicable size of the main line. It is for the purpose of provision.

The underline connecting branch connector of the present invention is provided with a trapezoidal groove that communicates in the lateral direction on the lower side of the front part of the main body upper member made of an insulator, with a gap in the length direction at the bottom of the groove, A notch groove is provided in which a main line lateral slip prevention fitting with a needle-like projection protruding downward can be fitted and removed, and a bolt hole with a screw is provided at the rear end of the main body upper member, and left and right of the bolt hole. A guide pin hole is provided, and on the front upper side of the main body lower member made of an insulator, a concave groove communicating in the lateral direction is provided at a position facing the trapezoidal groove of the main body upper member, and immediately below the concave groove, A through-hole for inserting the underline is provided in parallel with the concave groove, and a needle electrode provided with a needle-like protrusion projecting up and down at a position facing the cut groove at the bottom of the concave groove is the through-hole. A needle electrode insertion hole that can be moved up and down is provided. An insertion hole through which the main body fastening bolt is inserted is provided at a position facing the bolt hole of the main body upper member, and a guide pin that advances and retreats in the guide pin hole is provided at a position facing the guide pin hole of the upper body member. It is characterized by being.

Since the present invention is configured as described above, the following effects can be obtained.
(1) Since the needle electrode pierces the conductors of the main line and the underline at the same time and electrically connects them, it is not necessary to strip the insulator of the underline.
(2) The main line lateral deviation prevention metal fitting can pierce the main line and prevent the main line lateral deviation.
(3) The applicable size of the main line can be expanded.

For the purpose of providing a connector for connecting the underline with which the insulation of the underline can be omitted and the main line can be prevented from shifting laterally, the main line lateral slip prevention metal fitting with a needle-like protrusion protruding downward and the needle-shaped protruding vertically This was achieved by using a needle electrode with protrusions.

An embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 to 2, a trapezoidal groove 1 communicating in the lateral direction is provided on the lower side of the front portion of the main body upper member A made of an insulator such as polyacetal, and the bottom of the groove 1 is longitudinally connected. Bolts provided with cut grooves 3 and 3, which can be fitted to and detached from the main line lateral displacement prevention metal fitting 2 with needle-like protrusions protruding downward, with a gap between them, and a screw is engraved at the rear end of the upper body member A A hole 4 is provided, and guide pin holes 5 and 5 are provided on the left and right sides of the bolt hole 4.

On the front upper side of the lower body member B made of an insulator such as polyacetal, as shown in FIG. 1, a concave groove 6 communicating in the lateral direction is provided at a position facing the trapezoidal groove 1 of the upper body member A. A through-hole 7 for inserting the underline b is provided immediately below the groove 6 in parallel with the groove 6 and protrudes vertically at a position facing the cut grooves 3 and 3 at the bottom of the groove 6. Needle electrode insertion holes 9, 9 in which the needle electrode 8 having the needle-like projections can be moved up and down to the through hole 7 are provided.

As shown in FIG. 1, a screw that is screwed into the screw of the bolt hole 4 of the main body upper member A is provided at the rear end portion of the main body lower member B at a position facing the bolt hole 4 of the main body upper member A. An insertion hole 11 through which a body fastening bolt 10 made of an insulator such as a polycarbonate (hereinafter abbreviated as PC) is inserted is provided at a position facing the guide pin holes 5 and 5 of the body upper member A. Guide pins 12, 12 made of an insulator such as a PC that advances and retreats in the guide pin holes 5, 5 are provided.

In FIG. 1, reference numeral 13 denotes a screw hole for the underline temporary fixing bolt 14 made of an insulator such as a PC for fixing the underline b.

In implementation, if the size of the main line a is not large, it is not necessary to fit the main line lateral slip prevention metal fitting 2 to the main body upper member A, and the underline b is inserted into the through hole 7 of the main body lower member B and pulled. After the underline b is fixed by the underline temporary fixing bolt 14 and the needle electrode 8 is mounted in the needle electrode insertion holes 9 and 9, the main body upper member A is temporarily connected by the main body tightening bolt 10 to When the trapezoidal groove 1 is hung on the main line a and the main body fastening bolt 10 is tightened, the main line a and the pull-up line b are electrically connected via the needle electrode 8 as shown in FIG.

When the size of the main line a is large, when the main line lateral deviation prevention metal fitting 2 is fitted to the main body upper member A and the same procedure is repeated, as shown in FIG. 3B, the main line a and the pulling line b Are electrically connected via the needle electrode 8. In FIG. 3B, 15 is a spacer for preventing overtightening.

In addition, if a waterproof material such as a silicon compound is applied to the trapezoidal groove 1 of the main body upper member A, the concave groove 6 of the main body lower member B, and the through hole 7, the connecting portion may be finished in a watertight structure. It is preferable because it is possible.

Since it is not necessary to strip the insulation of the underline, and because it can be applied to multi-size main lines by using main line lateral slip prevention metal fittings, it can economically handle uninterruptible work requiring urgent.
