Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a joint box, and more particularly to a joint box that electrically connects a plurality of electric wires to each other.

[Background technology] Generally, when connecting multiple electric wires, the ends of the wires are inserted into a ring sleeve, the ring sleeves are caulked to join the wires, and insulating tape is placed around the ring sleeve for insulation. Although winding is commonly used, it is a cumbersome process and, depending on how the ring sleeve is crimped, the electrical wire connection may become incomplete, which poses a safety problem. On the other hand, there is a device that fixes the connector on the base and connects the wires using the connector, but since the number of terminals on the connector is fixed, the number of wires to be connected is There is a problem that the number of terminals of the connector does not match, and terminals to which electric wires are not connected may remain, resulting in an uneconomical situation.

[Object of the Invention] The present invention has been made in view of the above points, and its main purpose is to provide a joint box in which electric wires are electrically connected using a connector. The purpose is to match the number of terminals of each connector to the number of wires to be connected so that there are no surplus terminals.

[Disclosure of the Invention] Hereinafter, embodiments of the present invention will be described based on the drawings. In the joint box according to the present invention, a plurality of locking members 2 are housed in a housing 1, and electric wires 4 each inserted through a plurality of insertion openings 3 opened at one end of the housing 1 are connected to the corresponding locking members 2.
a connector 5 for holding the electric wires 4 together and electrically connecting the electric wires 4 to each other, a base 6 to which the plurality of connectors 5 are fixed, and a cover 7 that engages the base 6 and covers the insertion opening 3 of the connector 5. A holding hole 8 into which a plurality of connectors 5 are inserted is formed in the base 6, and a holding member is provided in the holding hole 8 to press the connectors 5 from one end of the holding hole 8 to the other end in the width direction. 9 is disposed, and the connector 5 is sandwiched within the holding hole 8 between one side wall of the holding hole 8 and a pressing member 9.

As shown in FIGS. 3 and 4, the connector 5 is constructed by housing a plurality of locking members 2 in a housing 1 formed in a substantially hexahedral shape. A plurality of insertion openings 3 are opened corresponding to each locking member 2. Housing 1
A conductive member 12 is disposed inside the housing 1 along the inner peripheral surface of the housing 1, and a plurality of electric wires 4 each inserted through the insertion opening 3 are sandwiched between the locking member 2 and the conductive member 12. By doing so, the electric wires 4 are electrically connected by the conductive member 12. In the figure, 22 is a partition plate that partitions between adjacent locking members 2 and prevents the electric wires 4 from getting entangled;
is a cover plate that closes one side of the housing 1. Various types of connectors 5 configured in this manner are available, each having a different number of insertion ports 3.
As shown in FIG. 1, the connectors 5 having different numbers of insertion ports 3 are formed so that only the lengths of the sides of the insertion ports 3 in one direction substantially orthogonal to the mouth axis direction are different. Therefore, when a plurality of connectors 5 are arranged in a straight line along the direction in which sides of different lengths run, the side surfaces of the connectors 5 are arranged substantially flush. The connector 5 is disposed on a base 6, and the base 6 is formed into a shape in which approximately L-shaped legs extend downward at both ends of an elongated body. A holding hole 8 is opened upwardly in the upper surface of the body. The width of the holding hole 8 is larger than one side of the connector 5, and the holding hole 8 has an elongated opening so that a plurality of connectors 5 can be accommodated in the holding hole 8. As shown in FIG. 2, a cap screw 13 is inserted into one side wall in the width direction of the body of the base 6, and the tip of the cap screw 13 projects into the holding hole 8. A cap screw 13 protruding into the holding hole 8
A holding plate 14 is disposed at one end of the holding member 9, and the holding screw 13 and the holding plate 14 constitute a holding member 9. Here, the cap screw 13
When the holding hole 8 rotates, the holding plate 14 moves back and forth in the width direction within the holding hole 8 in accordance with the rotation.
Therefore, by rotating the cap screw 13 with the connector 5 inserted into the holding hole 8, the connector 5 can be held between the holding plate 14 and one side wall of the holding hole 8. In this way, a plurality of connectors 5 can be fixed at desired positions on the base 6, and a plurality of connectors 5 having different numbers of terminals, that is, numbers of insertion ports 3 can be arranged on one base 6. Accordingly, a joint box having a desired number of terminals can be constructed. Base 6
Connecting protrusions 16 each having an engagement hole 15 are provided at both ends of the body, and the engagement hole 15 is provided with a cover 7 whose lower surface is open in a larger area than the upper surface of the body of the base 6. An engagement piece 17 extending from the lower edge is inserted. A hook portion 18 is formed at the lower end of the engagement piece 17 , and this hook portion 18 engages with the periphery of the engagement hole 15 . There are long mounting holes 19 in the legs of the base 6.
is formed, and by inserting a fixing tool such as a screw through this attachment hole 19, the base 6 is fixed to a wall or the like. Since the attachment hole 19 is a long hole elongated in the width direction of the base 6, the position can be adjusted when the base 6 is attached to a wall or the like. In the above example, the connector 5 is housed on the top surface of the base 6, but the same effect can be achieved even if the holding hole 8 is opened to the side of the base 6. be.

The one shown in FIG. 5 is a second embodiment, in which a coiled presser spring 21 is used instead of the presser screw 13.
The presser spring 21 and the presser plate 14 constitute the presser member 9. This presser spring 21 presses the presser plate 14 from one side wall of the holding hole 8 toward the other side wall. Of course, the presser spring 21 may be a plate spring in addition to a coiled spring. Also, the 6th
As shown in the figure, the presser plate 14 and the presser spring 21, which is a leaf spring, may be integrally formed of elastic synthetic resin.

[Effects of the Invention] As described above, the present invention is a joint box in which a plurality of connectors for electrically connecting a plurality of electric wires inserted into a housing are arranged on a base. A holding hole into which a plurality of connectors are inserted is formed, and a holding member is provided in the holding hole to press the connectors from one end of the holding hole in the width direction to the other end, and the connector is held in one of the holding holes in the holding hole. In a joint box that uses connectors to electrically connect wires to each other because they are held between the side wall and the holding member, various connectors with different numbers of terminals are combined and arranged on one base. This has the advantage that the number of terminals of each connector can be matched with the number of wires to be connected, and the wires can be connected without leaving any terminals left over.
