Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a flat cable connector used in an undercarpet wiring system.

[Conventional technology]

A conventional flat cable connector is shown in FIG. As shown in Figure 2, the flat cable 5
1, 52 in a T-type branch connection, connect the flat cable 51 on the main line side to the connector body 53,
A plug 54 is attached to the flat cable 52 on the branch side. The connector body 53 is fixed to the floor and has a blade holder (not shown) in the blade receiving hole 55. The insert 54 has a plug blade 56 .
The insertion tool 54 is held by the connector main body 53 by fitting the plug blade 56 into the plug blade receiver and by fitting the plug blade 56 into the plug blade receiver.
This is achieved by abutting the connector body 53 and the connector main body 53 on their opposing surfaces.

[The problem that the idea aims to solve]

However, the connector body 53 for flat cable
should be as thin as a carpet so as not to obstruct the floor surface. Therefore, there is a problem in that the area where the connector body 53 and the insert 54 are in contact with each other is small, and the connector body 53 is insufficiently able to hold the insert 54. The conditions of use on the floor are severe, and if the holding is unreliable in this way, the insert 54 may come off unexpectedly.

In addition, when drilling holes in the carpet during construction, the shape of the hole cannot be determined unless the insert 54 is inserted into the connector body 53, so it is necessary to insert the insert 54 into the connector body 53 first. ,
He used it as a ruler to make holes in the carpet. Therefore, the process of drilling holes in the carpet was complicated.

The purpose of this invention is to provide a flat cable connector that can securely hold the plug by the connector body and also facilitate drilling holes in the carpet during construction. be.

[Means to solve the problem]

The flat cable connector of this invention consists of a flat rectangular connector body that has a plug blade hole on the side and is installed on the floor, and an insert that has a plug blade that is inserted into the plug blade hole. and a pair of guide protrusions that protrude from both ends of the side surface of the connector body and engage the insert so that it can move in the insertion and removal direction, and the length of the guide protrusion and the length of the insert are equal. However, the connector body and the plug are approximately the same thickness as the carpet.

[Effect]

According to the configuration of this invention, since a pair of guide protrusions into which the insert fits are provided at both ends of the side surface of the connector main body, the contact area between the connector main body and the insert is increased. Therefore, even if the connector body and the plug are as thin as the carpet, the plug can be held securely. Furthermore, since the insert tool is guided by the guide protrusion when inserted, the plug blade and the plug blade receiving hole are prevented from being misaligned, and the insertion tool can be inserted smoothly.

Furthermore, since the length of the guide protrusion and the length of the insert are equal, when the insert is inserted, the entire insert fits between the pair of guide protrusions. Therefore, the shape of the hole to be drilled into the carpet during construction is determined by the connector body provided with the guide protrusion, and there is no need to go to the trouble of inserting an insert when drilling into the carpet during construction. It is possible to easily drill holes in the carpet by using only the connector body provided with the guide protrusion as a ruler.

〔Example〕

An embodiment of this invention will be explained based on FIG. FIG. 1 is an exploded perspective view of a flat cable connector according to an embodiment of this invention.

In Figure 1, 1 is the trunk side flat cable laid on the floor, and the connector body 2 is placed on top of it.
is placed and fixed to the floor. The connector main body 2 has a flat rectangular shape, and has a plug blade receiving hole 3 on the side.
A plug blade receiver (not shown) in the plug blade receiving hole 3 is connected to each conductor 1a of the flat cable 1. A pair of guide protrusions 5 into which the plug 4 is fitted are integrally formed at both ends of the side surface of the connector main body 2, and a pair of guide protrusions 5 into which the plug 4 is fitted are formed on the inner surface of one of the guide protrusions 5 along the insertion direction of the plug 4. A fitting groove 6 is provided.

The insert 4 is provided with a plug blade 7 that is inserted into the plug blade receiving hole 3, and a flat cable 8 on the branch side is connected thereto. The plug blade 7 may be pin-shaped. The insert 4 is integrally formed with a protrusion 9 on one side to prevent incorrect insertion, which fits into the fitting groove 6.

The connector main body 2 and the insert 4 are made to have the same thickness as a carpet (not shown), and the length of the guide protrusion 5 and the length of the insert 4 are made equal.

According to this embodiment, a pair of guide projections 5 for fitting the plug 4 are provided on both ends of the side surface of the connector body 2, so that the contact area between the connector body 2 and the plug 4 is increased. Therefore, even if the thickness of the connector body 2 and the plug 4 is as thin as a carpet, the plug 4 can be securely held. In other words, the plug 4 is prevented from swinging left and right or up and down or from falling out, and can withstand harsh conditions of use on a floor. In addition, since the plug 4 is guided by the guide projections 5 when it is inserted, the blades 7 and the blade receiving holes 3 are prevented from being misaligned, and the insertion operation is performed smoothly. In addition, since the contact area between the connector body 2 and the plug 4 is increased, it is easy to provide a structure that prevents the ingress of water and dust.

Furthermore, one guide protrusion 5 is provided with a fitting groove 6, and the insert tool 4 is provided with an incorrect insertion prevention protrusion 9, so that
The insertion tool 4 is not inserted upside down, and the polarity is not connected incorrectly.

Furthermore, since the length of the guide protrusion 5 and the length of the insert 4 are made equal, when the insert 4 is inserted, the entire insert 4 fits between the pair of guide protrusions 5. It's crowded. Therefore, the shape of the hole to be drilled in the carpet at the time of construction is determined by the connector body 2 provided with the guide protrusion 5, and there is no need to take the trouble to insert the insert tool 4 when drilling a hole in the carpet at the time of construction. Therefore, it is possible to easily drill holes in the carpet using only the connector main body 2 provided with the guide protrusion 5 as a ruler. Further, the overall size can be made equal to that of the conventional example shown in FIG. 2, and it can be fitted into the notch hole of the existing carpet without any gaps.

[Effect of idea]

The flat cable connector of this invention is provided with a pair of guide protrusions on both ends of the side surface of the connector body into which the plug fits, increasing the contact area between the connector body and the plug. Therefore, even if the thickness of the connector body and plug is as thin as the carpet,
The insert can be held securely. Furthermore, since the insert tool is guided by the guide projection when it is inserted, the plug blade and the plug blade receiving hole are prevented from being misaligned, and the insertion work is performed smoothly.

Furthermore, since the length of the guide protrusion and the length of the insert are equal, when the insert is inserted, the entire insert fits between the pair of guide protrusions. Therefore, the shape of the hole to be drilled in the carpet during construction is determined by the connector body provided with the guide protrusion, and there is no need to take the trouble to insert an insert when drilling holes in the carpet during construction. It is possible to easily drill holes in a carpet by using only the connector body provided with the guide protrusion as a ruler.
