Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application] The present invention relates to a flat cable connector. More specifically, the present invention relates to a connector for branching or connecting flat cables in wiring systems for electrical equipment in intelligent buildings and the like.

[Background of the invention] In order to respond to the needs of a highly informed society in response to technological advances and social movements, various systems such as telecommunications, office automation, and building automation are integrated into buildings. Intelligent buildings have been put into practical use from the concept of organically making buildings intelligent.

Among the various methods of wiring systems for office buildings, there is a method that uses flat cables that can be laid under the carpets of building floors, that is, undercarpet cables.

Traditionally, this method involves an undercarpet cable placed under the carpet and a cable that rises up from the cable and connects to the ground floor in the office.
Clip terminals and interface connectors were used for undercarpet cables to connect input and output cables of AFI devices and the like.

However, when using Clip Terminal, O
When adding, moving, or changing equipment A, it is necessary to change the wiring of the undercarpet cable each time.

Furthermore, when using an interface connector, if you leave the connector that connects to the device uninserted, the opening of the insertion part is open, making it easy for dust and liquid to enter. Poor contact may cause problems with the pond.

Additionally, connecting the interface connector to the end of the undercarpet cable has the additional disadvantage that the cable cannot be extended from the end of the cable.

[Object of the Invention] In view of the many problems described above that need to be solved, the object of the present invention is to route a flat cable under a carpet and then place it at any location on the cable. The purpose of the present invention is to provide a flat cable connector that can be used for flat cables.

Another object of the invention is to move various 0Afi devices after installing undercarpet cables, and to lay out equipment indoors. - To provide a flat cable connector that can easily change the connection between these devices and the cable.

A further object of the invention is to provide a flat cable connector that allows the extension of a wired flat cable.

Another object of the present invention is to provide a flat cable connector that can prevent the intrusion of dust and other substances by blocking the opening of the connector that connects the flat cable and the input/output cable of the 011 device. be.

[Configuration of the Invention] Preferred embodiments of the present invention are described with reference to the accompanying drawings.
Explain to phase.

First, as shown in FIG. 1, the flat cable connector 10 of the present invention includes a substrate 12 fixed on a flat surface of the floor, and a housing 14 attached on the substrate 12. As shown in FIGS. 4 and 5, a plurality of contact members 1G are installed on the substrate 12 and assembled into an insulating block 18.

The contact member 1G is a pressure welding terminal 20 with both ends upright.
．． 21, undercarpet gape C
This allows the end of the cable to be inserted and the conductor of the cable to be crimped. F in the middle part of contact member 1G
P C (rfcxibla Printad C1rc
uit) The top is formed in a shape suitable for forming a connecting portion 22 into which one end of the cable F is inserted and its conductor is press-contacted.

Insulating block 17 for incorporating contact member 16 1
8 has an opening 24 into which the connecting portion 22 of the FPC cable F is inserted, and the press-connecting terminals 20, 21 of the undercarpet cable C are exposed outward from both ends thereof, as shown in FIG.

The insulating block 18 incorporating the contact member 1G is fixed to the substrate 12 by suitable fixing means, such as screw rivets.

A housing 14 mounted on the substrate 12 extends from one end of the substrate 12 to the contact member 1, as shown in FIG.
6, an upright wall 32 that stands upright from inside the flat ceiling 28; An arcuate cover portion 34 forms an arc from the top to the other end of the substrate 12.

An interface connector 30 is fixed to the inner surface of an upright wall 32 of the housing 14, and an opening 3G for accessing the interface connector 30 is formed in the upright wall 32. During this time [0A via 3G]
The connector attached to the end of the input/output cable connected to the FFFI device or the like is inserted into the socket of the interface connector 30 and connected.

A rotatable cover 38 is attached to the arcuate cover portion 34 so as to rotate around a shaft member 40 to open and close, so that the rotatable cover 38 can cover the entire surface of the flat ceiling 28 from the upright wall portion 32 of the housing 14. be.

Therefore, when there is no need to connect a 2R connector with r = t to the end of the input/output cable of an 0Afi device, etc., to the interface connector 30, the rotatable cover 38 is rotated around the shaft member 40. It can be placed in the closed position as shown in Figure 1.

In order to connect the undercarpet cable C to the pressure welding terminals 20 and 21 of the contact member 1G disposed inside the housing 14, an opening 42 for inserting the undercarpet 1 to the cable C is provided in the lower part of the housing 14. be.

[Operations and Effects of the Invention] As described above in detail, the flat cable connector 10 of the present invention has a coffin structure, so that one side of the undercarpet cable C (M of the undercarpet cable C; After connecting the pressure welding terminal 20 and wiring the cable C, the other terminal 21 can be used to extend the cable C as necessary for moving the AlfiRα. 1G is provided with pressure contact terminals 20 and 21 at both ends, so the connector 10 can be connected to a desired portion of the cable C.

According to this invention, the connecting portion 22 at the center of the contacts 1 to 16 and the interface connector 30 fixed to the upright wall portion 32 of the housing 14 are connected by the F'pc cable F. Since the connection between the N device and the connector 10 can be made freely via the ;I connector of each cable of the OAR device, changes in the layout of the device can be easily carried out.

In particular, the connector 10 of the present invention has a rotatable cover 3.
8, so if the interface connector 30 and the O1L device are not connected, rotate this rotatable cover 38 around the shaft member 40 to open the opening 32 of the interface connector 30. Since the temperature can be closed, dust and dirt can be prevented from entering the opening 32.
