Description

  The present invention relates to a direct-mounted lighting fixture that is directly attached to a ceiling surface of a house or the like by connecting and fixing an adapter to a hooking ceiling body.

  As an example of a conventional lighting fixture, there is one in which a connector connected to the tip of a lead wire is attached to an adapter (see, for example, Patent Document 1).

JP 2008-47360 A (FIG. 1, paragraph number 0021)

However, in the conventional lighting fixture disclosed in Patent Document 1, the lead wire drawn out from the connector is drawn out downward in the same axial and reverse direction as the insertion direction of the connector.
Therefore, in the lighting apparatus of Patent Document 1, when the lead wire is pulled out in a direction perpendicular to the insertion direction of the connector, even if the lead wire is bent in a direction perpendicular to the connector drawing portion, at least the diameter of the lead wire is equal to Protruding from the connector body was a factor that hindered thinning.

On the other hand, there has also been proposed a lighting fixture in which the lead wire is drawn out in a direction perpendicular to the insertion direction of the connector and the lead wire is regulated by the connector cover. In such a lighting fixture, the lighting fixture is applied to the lead wire. Tension is transmitted directly to the connector cover.
Therefore, in such a lighting fixture, it is necessary to firmly fix the connector cover, which may cause an increase in the size of the connector.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a lighting apparatus that can be thinned and that can simplify the fixing of the connector cover and reduce the size of the connector.

  The luminaire according to the present invention is a luminaire having a connector for electrically connecting to an adapter for mechanically and electrically connecting and holding the fixture body by being connected and fixed to the hooking sealing body, A connector body made of an insulating material, a contact terminal having a quick-connection terminal portion built in the connector body, and a connector cover that covers the rear end side of the connector and prevents the contact terminal from coming off, The connector body is characterized in that an electric wire insertion hole for connecting the lead wire to the quick connection terminal portion is arranged in a direction orthogonal to the insertion direction of the connector.

In the present invention, an electric wire insertion hole for connecting a lead wire to the quick connection terminal portion is formed in the connector body in a direction orthogonal to the insertion direction of the connector.
As a result, in the present invention, the lead wire is pulled out through the independently formed wire insertion hole without contacting the connector cover, so that the tension applied to the lead wire is applied to the inner surface of the wire insertion hole. As a result, the tension applied to the lead wire is not transmitted to the connector cover.
Therefore, in the present invention, it is not necessary to firmly fix the connector cover, so that the connector can be reduced in size and the entire thickness can be reduced.

  The lighting fixture according to the present invention is characterized in that, in the lighting fixture described above, the outer surface of the connector protruding from the connector main body of the wire insertion hole also serves as a stopper for limiting the insertion depth of the connector.

In the present invention, since the connector is L-shaped by the outer surface protruding from the connector main body of the electric wire insertion hole, the outer surface is inserted into the adapter when inserted to be electrically connected to the adapter. Insertion is stopped at the contacted position.
Thereby, in this invention, the outer surface of an electric wire insertion hole functions as a stopper of the insertion direction of a connector.
Therefore, in the present invention, the insertion depth of the connector into the adapter can be easily set by the outer surface of the wire insertion hole. In addition, the lead wire can be moved away from the rear end side of the connector to the front end side, and a knob allowance for attaching and detaching the connector can be secured.

  In the lighting fixture according to the present invention, in the lighting fixture, the quick connection terminal portion of the contact terminal includes a conductive portion to which a core wire of the lead wire is pressed and a locking portion to press the core wire, and the conductive The portion is arranged on the front end side of the connector, and the locking portion is arranged on the rear end side of the connector, respectively.

In the present invention, the contact terminal has a conductive portion and a locking portion in the quick connection terminal portion, the conductive portion is disposed on the distal end side of the connector, and the locking portion is disposed on the rear end side of the connector.
Thereby, in this invention, the shape of a contact terminal can be made into the simple shape rich in versatility.
Therefore, in the present invention, the type of the contact terminal can be single. In addition, since the developed shape of the contact terminals is close to a rectangle and the yield is good, efficient production can be performed.

In the present invention, the conductive portion to which the core wire of the lead wire is pressed is disposed on the distal end side of the connector.
Thereby, in this invention, an electric wire insertion hole is arrange | positioned in the position close | similar to an adapter.
Therefore, in the present invention, by securing the distance of the lead wire from the lamp, the influence of heat, ultraviolet rays, etc. on the lead wire can be reduced.

  In the lighting fixture according to the present invention, in the lighting fixture, the connector has a retaining lock portion from the adapter, and a release lever that is pressed against the connector main body side to release the lock has a surface with the wire insertion hole. It is provided on the surface opposite to the above.

In the present invention, the release lever is unlocked by the retaining lock portion by picking it with a finger or the like and pressing it against the connector body side. At this time, since the release lever is provided on the surface opposite to the surface having the wire insertion hole, the release operation is performed by grasping the release lever and the surface on the wire insertion hole side with a finger.
Thereby, in this invention, the knob margin at the time of cancellation | release operation of a cancellation | release lever is ensured.
Therefore, in this invention, the operativity of cancellation | release operation by a cancellation | release lever can be improved.

  In the lighting fixture according to the present invention, in the lighting fixture, the connector cover is integrally formed by a hinge on a surface having the wire insertion hole, and the hinge has a convex shape on a surface having the wire insertion hole. It is arranged so that it may be arranged.

In the present invention, the hinge is formed in a convex shape on the surface with the wire insertion hole.
Thereby, in this invention, when attaching / detaching a connector, a finger | toe can be hooked on a convex-shaped part.
Therefore, in the present invention, it is easy to pick when the connector is attached or detached, and the attachment / detachment operability can be improved. In addition, since the connector main body and the connector cover are integrated at the time of molding, the number of parts can be reduced and the number of assembly steps can be reduced.

According to the lighting fixture of the present invention, the connector has an electric wire insertion hole for connecting a lead wire to the quick connection terminal portion in the connector main body arranged in a direction orthogonal to the insertion direction of the connector.
Thereby, according to the lighting fixture of this invention, it has the effect that it can reduce in thickness while simplifying fixation of a connector cover and a connector.
