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 a plurality of 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 base 6 to which the plurality of connectors 5 are fixed, and a cover 7 that engages with the base 6 and covers the insertion opening 3 of the connector 5. The base 6 has a holding hole 8 into which a plurality of connectors 5 are inserted.
are formed, and a holding piece 10 having a hook 9 at the tip thereof extends from the opening edge of the holding hole 8 in correspondence with each connector 5 inserted into the holding hole 8,
This is characterized in that when the connectors 5 are inserted into the holding holes 8, hooks 9 are respectively engaged with the upper surfaces of the connectors 5 to prevent the connectors 5 from coming off.

As shown in FIGS. 2 and 3, the connector 5 is constructed by housing a plurality of locking members 2 in a housing 1 formed in a substantially hexahedral shape. An insertion port 3 opens corresponding to each locking member 2. A conductive member 12 is disposed in 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 connected between the locking member 2 and the conductive member 12. While being sandwiched, the electric wires 4 are electrically connected to each other by the conductive member 12. In the figure, 22 is a partition plate that separates adjacent locking members 2 and prevents the electric wires 4 from getting entangled, and 23 is a cover plate that closes one side of the housing 1. Various types of connectors 5 having different numbers of insertion ports 3 are available as the connectors 5 configured in this way, and as shown in FIG. They are formed so that only the lengths of the sides in one direction perpendicular to the axial 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, both side surfaces of the connectors 5 are arranged flush with each other. The connector 5 is disposed on a base 6, and the base 6 is formed into a shape in which a substantially L-shaped body extends downward from each end of a long and thin plate-like body. A holding hole 8 is opened upwardly on the upper surface of the body. The holding hole 8 has a width approximately equal to one side of the connector 5, and is opened in an elongated shape so that a plurality of connectors 5 can be accommodated at the same time. A plurality of holding pieces extend upward from both sides of the opening edge of the holding hole 8 in the width direction, and a hook 9 protrudes from each holding piece 10 in a direction that reduces the distance in the width direction of the holding hole 8. It is set up. The base 6 is made of an insulating and flexible material such as synthetic resin, and has a slit of a predetermined width along the opening edge of the holding hole 8. By providing this, spring properties are imparted to the holding piece 10, and the holding hole 8 of the connector 5 is
The holding piece 10 is bent when the connector 5 is inserted into the holding hole 8, and the holding piece 10 returns to its original position with the connector 5 completely inserted into the holding hole 8, and the hook 9 is inserted into the connector 5.
It is designed to be secured to the top surface of the In this way, a plurality of connectors 5 can be inserted into desired positions on the base 6, and by arranging a plurality of connectors 5 with different numbers of terminals on a single base 6, desired terminals can be inserted. It is possible to construct a joint box with numbers. The base 6 has connecting protrusions 1 each having engagement holes 15 at both ends of the body.
6 is provided protrudingly, and in this engagement hole 15 is a cover 7 whose lower surface is open in an area larger than the upper surface of the body of the base 6.
It is inserted into an engaging piece 17 extending from the lower end edge of. 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. Elongated attachment holes 19 are formed in the legs of the base 6, and by inserting a fixing device such as a screw through the attachment holes 19, the base 6 is fixed to a wall or the like. Since the attachment hole 19 is a long hole, the position of the base 6 can be adjusted when the base 6 is attached. In the above example, the connector 5 is housed in the holding hole 8 that opens upward, but the same effect can be obtained even if the holding hole 8 is opened to the side of the base 6. It is possible.

[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 is formed into which a plurality of connectors are inserted, and a holding piece having a hook at the tip extends from the opening edge of the holding hole in correspondence with each connector inserted into the holding hole. When a connector is inserted into a joint box, a hook is locked on the top surface of each connector to prevent the connector from coming off. Various connectors with different numbers of terminals can be combined and placed on one base, and the number of terminals on each connector can be matched to the number of wires to be connected, allowing connections between wires without leaving any terminals left over. This has the advantage that.
