Abstract

PROBLEM TO BE SOLVED: To provide a compression electric wire connector in which a corrugated sleeve and a curved sleeve having compression holes arranged in parallel are housed in an insulator case, an electric wire terminal inserted through an aperture part is bent and formed while being inserted into the sleeves and a bent hole, by which the electric wire is prevented from coming off and rotating with the compression force, and which can be compressed easily and reliably by universal compressing plier usable for other works. SOLUTION: In a corrugated sleeve 3 housed in an insulation case 1, a bent hole 2 is formed in the deep part in common with the compression hole of a bent sleeve and an electric wire terminal part 8 to be inserted into is bent and formed along the hole, and even in the case a rotating impact is applied intensely to the electric wire, rotation of the electric wire is prevented. In the compression plier, compression walls are formed to make it easy to press the connector and an adjustable case is formed as to adjust the grip to be long and lessen the needed grasping power, and if unnecessary, the grip can be shortened and is made easy to be handled.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present application relates to a compression type electric wire connector used for branch connection work in electric wiring work.

[0002]

2. Description of the Related Art A conventional ring sleeve has a single hole,
Randomly mix a plurality of wire terminals into this, compress them with dedicated crimping pliers, and wrap them with insulating tape.In the case of a plug-in wire connector, connect each wire terminal to the conductive plate and spring piece. It was inserted between them, and was pressed by a weak spring piece that could be inserted with the pressing force of one wire, and the end of the wire was always damaged at the tip.

[0003]

In the above ring sleeve, a plurality of electric wire terminals are mixed in one hole, and therefore, the damage and the mixing of the electric wires caused by crushing the electric wires by crimping the terminals while the terminals are intricately mixed. There are many problems such as the difficulty of using large and dedicated crimping pliers, which requires a strong grip by pressing to a certain position regardless of the number of terminals, the troublesomeness of carrying, and the insulating work after connection. It was Since the plug-in type wire connector has a structure in which the conductive plate and the pressing pressure spring piece are connected by pushing open with one wire end, the pressing force of the spring piece and its spring body are inevitably weak.
After the connection, many connection bundles need to be forcedly pushed into the joint box having a small accommodation space, and there are many problems such that the connection function inevitably deteriorates due to the impact.

[0004]

As a means for solving the above-mentioned problems, a plurality of compression holes are arranged in parallel in a metal ring having excellent conductivity and durability to form a corrugated sleeve. Or, the sleeve is curved to form a curved sleeve, which is housed in the back of the opening of the insulating case, and the hole leading to the back is curved, and the compression tool is assembled from the compression tool inlet of the insulation case. When the electric wire end is inserted through the mouth opening of the plugged connector, the tip end is bent and inserted. The head of the compression tool and the compression projection are pinched by the compression part of the compression pliers, the adjustment case provided at the end of the handle is extended, and the compression end of the compression tool is compressed by the grip force of the hand. The compression groove is compressed so that the entire wire is compressed along the outer circumference of the wire end, and the wire end portion inserted into the curved hole is prevented from rotating and fixed.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION An insulating case is provided with opening portions for guiding wire ends one by one, and a space for accommodating a corrugated sleeve or a curved sleeve is provided in the inner portion thereof, and the space is common in the inner portion thereof. A curved hole is provided, and a mounting port that incorporates a compression tool that advances and presses toward the flat surface of the stored sleeve is provided.The compression tool is inserted into this, and when the wire end is inserted from the mouth opening part, it is guided to the curved hole. It bends and stops, and when this connector is pinched in the compression hole of the compression pliers and compressed until the hanging protrusion of the compression tool is hooked in the hanging hole, the entire circumference of the wire end is compressed into the compression hole and the bent wire end is bent. Is fixed and does not shake, maintaining a stable conductive state. If a curved sleeve is used, the curved portion of the wire end becomes longer, the degree of fixing is higher, and the connection is firm and there is no shaking.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings showing an embodiment of the present application, an arrow A is a connector. 1 is an insulating case,
A space for accommodating the corrugated sleeve 3 or the curved sleeve 4 is provided in the back of the mouth opening 11, a common curved hole 2 is provided in the back of the mouth, and a compression for pressing the flat surface of the corrugated sleeve 3 or the curved sleeve 4 is provided. The structure is provided with a compression tool inlet 24 for mounting the tool 5 and a compression projection 12. The curved hole 2 is a curved hole provided in the back portion common to the opening 11 of the insulating case 1, is formed to be thin toward the back, and is guided and curved when the electric wire terminal 8 is inserted, and the electric wire is also formed. If the terminal 8 is thick, it will be full and stop halfway, and if it is thin, it will be filled to the back and will be automatically adjusted, etc. It does not fall off easily before the wire is compressed, and after compression it is curved so as to prevent the rotation even when a strong force such as rotation of the wire end 8 is exerted from the outside. It is a thing. The corrugated sleeve 3 has a plurality of circular compression holes 13 formed therein by crushing the surface of the ring for the time being, and has a flat bottom portion, which is housed in the insulating case 1 and the compression tool 5 is commercially available. When pressed with pliers or the like, the compression end 6 at the tip is compressed into the compression groove 2
5 is compressed, the entire compression holes 13 are contracted, and almost the entire electric wire end 8 is strongly pressed and wrapped, so that a complete conductive effect is obtained. The curved sleeve 4 is formed by compressing the flat surface and the bottom surface for the time being to form the compression holes 13 therein, and further, the sleeve is curved. In addition to obtaining the same operation and effect as the corrugated sleeve 3, the curved sleeve 4 is straight. When the wire end 8 is inserted from the opening 11, not only the tip is bent, but also the part that enters the bending sleeve 4 is bent to enhance the fixing degree and further stabilize the conductive force.
In addition to compressing the entire compression groove 25, the compression tool 5 can perform various forms of compression by forming the compression end portion 6 into an arbitrary shape, and particularly the front end portion and the rear end portion of the sleeve can be compressed. When compressing deeply, the compressive force is concentrated at both ends even with a comparatively light compressive force, and the wire end is strongly compressed. 7 is an electric wire. 9
Is a hanging hole, which is a pair of left and right windows of the compressor inlet 24, and the latching projection 10 engages only when the compressor 5 is pressed to a certain position, so that the user can intuitively check the compression. Reference numeral 12 is a compression protrusion, and when the connector A is inserted into the compression portion 15 of the compression pliers 14, the head of one compression tool 5 and the compression protrusion 1 of the other
Only make contact with No. 2 and make it project so as to compress, and make it thick and strong to withstand the compressive force. The compressing portion 15 is a recess that compresses the connector A by sandwiching it, and since the commercially available pliers have a shallow depth, the compressing tool 5 and the compressing projection 12 may be insufficiently deep enough to be used for other purposes. In order to enable compression without hindering, the compression wall 16 is provided so that the compression wall 16 can be securely sandwiched. 17 is compression pliers 14
It is the pattern. Reference numeral 18 denotes a spring groove, which is provided with an elongated groove at the center of the end portion of the handle 17 of the compression pliers 14, into which an elongated curved stop spring 20 is fitted, and which is fitted with an adjusting case 22 so that The curved portion has a function of pushing up the inside of the adjustment case 22, and stops at an arbitrary position. Reference numeral 19 is an edge stop groove, and a stop spring groove 18
Elongated shallow grooves are provided on both sides of the handle, and the stop edge 21 provided at the tip of the adjustment case 22 enters the groove of this portion to allow movement therebetween, and prevents the handle 14 from being detached from the end. In this way, when the connector A is compressed in the adjustment case 22, the adjustment case 22 is fully extended to strengthen the lever by the grip force of the hand, so that the compression work can be easily performed with a light grip force. 22 can be reduced to facilitate portability and can be used for general work like other pliers. 23 is a support part. Reference numeral 24 denotes a compression tool inlet, which is a space for inserting and moving the compression tool 5 forward and backward. Reference numeral 25 is a compression groove, which is an elongated groove formed by equally compressing a ring of one hole to form the compression hole 13.

The use of the curved hole 2 is not limited to the corrugated sleeve 3 and the curved sleeve 4 in which a plurality of compression holes 13 are arranged in parallel, and also to a connector having a structure in which electric wire terminals such as a conventional plug-in type electric wire connector are inserted one by one. It can be applied.

If a hard resin material is used as the material of the compression tool 5, it is safe even if the head is exposed, and at the same time the conductors such as the corrugated sleeve 3 and the curved sleeve 4 are not damaged during compression. Not only can it be reliably compressed and mass-produced, it is also lightweight and easy to handle and easy to carry.

Regarding the compression pliers 14, the connector A is
It can be sufficiently compressed with commercially available pliers, but is further provided with a compression wall 16 and an adjustment case 22 in order to pinch easily and securely and to enable compression with a lighter gripping force.

[0010]

EFFECTS OF THE INVENTION A straight electric wire terminal 8 which is provided with a curved hole 2 in the back part common to the mouth opening 11 and is inserted is automatically curved while being guided to the curved hole 2, and before compression. Even when the wire end 8 is compressed, the wire end 8 does not swing even when a strong force for rotating the wire end 8 is applied, and a stable conductive effect can be obtained.

The compression hole 13 of the curved sleeve 4 is curved, and the straight electric wire terminal 8 to be inserted is curved while being inserted into this hole, and the electric wire terminal once inserted does not easily fall off. The electric wire terminal 8 inserted in 2 is formed into a long curved shape to further prevent the turning-off prevention.

The shape of the compression hole 13 is not limited to a circular shape, and any shape such as a square shape, a rhombus shape, an elliptical shape or the like can be applied. Even if the sleeve has the same wave shape on the front and back sides, the surface has a wave shape. It is effective to form the bottom surface into a flat surface.

Since the corrugated sleeve 3 and the curved sleeve 4 are metallic bodies, they do not loosen even after compression, and moreover, the outer circumference of the wire end 8 is wrapped in a circular shape and compressed so that the wire end 8 is not damaged and the contact area is Is wide, and therefore the conductive effect is high and stable.

Since the sleeve having the compression holes 13 arranged in parallel, such as the corrugated sleeve 3 and the curved sleeve 4, has a hole diameter slightly larger than that of the electric wire terminal 8, not only can the terminals be connected regardless of their thickness, but also the stranded wire with a weak waist can be used. It can be inserted without trouble, and can be connected to one connector A by being confused with a single wire.

A compression wall 16 is attached to the compression portion 15 of the compression pliers 14.
Since the adjustment case 22 is provided at the end of the handle 17 so that it can be expanded and contracted and is fixed at any position by the action of the stop spring 20, the length can be adjusted freely, and even if the pliers themselves are small, the connector A of the present application can be completely The pliers themselves are not specially designed and can be used for other work as well as ordinary pliers. It is also versatile.
