Abstract

PROBLEM TO BE SOLVED: To prevent an electrically loose connection due to external drawing force, while securing good electric connection between a tape wire and a connector terminal. SOLUTION: In connecting a tape wire 2 and a connector terminal 3 by a clamping process, connecting pieces 32 of the connector terminal 3 are so made to pinch flat type conductors 21-24 penetrating an insulating tape 25 of the tape wire 2 and curling. Here, reinforcing member pinching pieces 33 behind the connecting pieces 32 pinch the insulating tape 25 and a reinforcing tape 26 hugging from both sides, so that an external force is loaded on the tape wires 2 of the reinforcing member pinching pieces 33 and the reinforcing tape 26, even if the external drawing force is loaded on the tape wire 2. Thus, the external force will hardly act on the clamped part of the tape wire 2 of the connecting pieces 32 and, therefore, electrically loose connection due to deformation or damage (such as breaking of wire) of the clamped part is prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape wire with terminals having connector terminals connected to both sides of a tape wire (for example, FFC; flexible flat cable, etc.) in a longitudinal direction, for example, used for wiring of vehicles and the like, and the terminals. The present invention relates to a wire harness using a tape wire with a wire.

[0002]

2. Description of the Related Art Conventionally, this kind of tape wire with terminals 10
Reference numeral 0 denotes a configuration in which connector terminals 102 are respectively crimp-connected to both sides in the longitudinal direction of the tape electric wire 101 as shown in FIG. The connector terminals 102 of the tape wire 100 with terminals are inserted into the connector housing 103 to form a wire harness 105 in which connectors 104 are respectively connected to both sides of the tape wire 101 in the longitudinal direction. This wire harness 105 is used for wiring such as a car roof and a door.

A tape electric wire 101 is a flexible flat conductor cable, and a plurality of rectangular conductors 101a arranged in parallel.
(For example, aluminum wire or copper wire) with insulating tape 10
1b is laminated from above and below to form a laminated structure. The connection between the tape electric wire 101 and the connector terminal 102 is made such that each of the connecting holding pieces 102a (hereinafter simply referred to as connection pieces) of the connector terminal 102 penetrate the insulating tape 101b and hold the rectangular conductor 101a from both sides. It is curled and connected to the rectangular conductor 101a.

[0004]

In the above-mentioned conventional wire harness 105, a tape electric wire 1 as shown by an arrow X is used.
01, when a pull-out external force is generated, the pull-out external force is applied to the connector housing 103 and the connector terminal 102.
At the same time, it acts also at the crimping portion between each connecting piece 102a of the connector terminal 102 and the tape wire 101. Due to this external force, there is a problem that the tape wire 101 in the crimped portion may be deformed or damaged (such as disconnection), thereby causing a poor electrical connection.

In this case, it is conceivable to reinforce the caulked portion between each connection piece 102a of the connector terminal 102 and the tape wire 101 by, for example, increasing the thickness of the tape wire 101. However, the degree of caulking tends to be reduced by the thickness of the caulked portion. When the crimping degree of the crimping portion is reduced, the contact pressure of the crimping portion is reduced, and there is a possibility that a poor electrical connection occurs in the crimping portion.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems, and prevents the occurrence of a poor electrical connection due to the external force of pulling out a tape wire while securing a good electrical connection between the tape wire and a connector terminal. It is an object of the present invention to provide a terminal-attached tape electric wire and a wire harness.

[0007]

A tape wire with terminals according to the present invention is a tape wire with terminals in which a connector terminal is connected to a longitudinal end of the tape wire. The connector terminal is provided with a connecting clip for electrically connecting the connector terminal to the conductor portion of the tape wire, and a reinforcing member clip is provided at the rear of the connecting clip of the connector terminal. Is provided, and the connecting clip is crimped to be electrically connected to the conductor portion of the tape wire, and the reinforcing member clip is crimped to clamp the tape wire and the reinforcing member. It is characterized by the following. In this case, the tape electric wire is a flexible flat cable (for example, FFC; including a flexible flat cable) in which a plurality of conductor wires arranged in parallel are covered with a flexible insulating material. Preferably, in the wire harness of the present invention, the connector terminal of the tape wire with terminal according to claim 1 is inserted into the connector housing.

According to these configurations, the connecting terminal of the connector terminal is crimped to penetrate the tape wire, and the reinforcing member connected to the rear of the connecting terminal of the connector terminal is provided. Even if external force acts on the tape wire, the external force acts on the portion where the reinforcing member sandwiches the tape wire and the reinforcing member because the holding piece is crimped to hold the tape wire and the reinforcing member. By doing so, an external force is less likely to act on the electrical connection portion of the connector terminal, and the occurrence of electrical connection failure due to deformation or breakage (such as disconnection) of the caulked portion is prevented. That is, good electrical connection between the tape wire and the connector terminal is ensured regardless of the external force.

Preferably, the reinforcing member of the terminal-attached tape electric wire of the present invention has a pinching projecting portion projecting from the main body portion continuous in the width direction of the tape electric wire to the connector terminal side according to each connector terminal. The reinforcing member sandwiching piece penetrates the tape wire and sandwiches the tape wire and the holding protrusion.

[0010] With this configuration, the reinforcing member holding piece only needs to penetrate the tape wire, and does not need to penetrate the reinforcing member. Therefore, the force required for caulking is small, and it becomes easier to clamp the reinforcing member clamping piece to the tape wire and the clamping projection.

Further, preferably, the reinforcing member in the tape wire with terminals of the present invention is constituted by a reinforcing tape, and the reinforcing tape is attached to a predetermined portion on the tape wire.

With this configuration, the portion where the reinforcing tape is stuck to the tape wire becomes a rigid portion, so that the operability when manually or automatically inserting the connector terminal into the connector housing is improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of a tape wire with terminal and a wire harness to which the present invention is applied will be described below with reference to the drawings.

FIG. 1 is a perspective view showing the configuration of a tape wire with terminals and a wire harness according to an embodiment of the present invention. In FIG. 1, a tape wire 1 with terminals is configured such that connector terminals 3 are connected to both longitudinal sides of a tape wire 2. The connector terminals 3 of the tape wire 1 with terminals are inserted into the connector housing 4 to form a wire harness 10 in which the connectors 5 are respectively connected to both sides of the tape wire 2 in the longitudinal direction.

As shown in FIGS. 1 and 2, the tape electric wire 2 is made of rectangular conductors 21 to 24 (for example, having a conductive cross-sectional area of 0.3 mm ²⁾ as four thin circuit conductors such as an aluminum wire or a copper wire. ) Are arranged side by side in parallel, and the insulating tape 25
Are pasted together. A reinforcing tape 2 having a predetermined length substantially the same as the width of the tape wire 2 is provided at an appropriate position on the tape wire 2.
6 is pasted. The reinforcing tape 26 is made of, for example, a PET film (polyethylene terephthalate film, also known as polyester) having a thickness of 188 μm.

As shown in FIG. 2, the connector terminal 3 is electrically connected to a mating connector terminal (not shown).
For example, a connection terminal portion 31 capable of fitting connection and the like and a bottom wall 34 extending rearward from the connection terminal portion 31 are provided so as to face each other from both sides of an intermediate portion of the bottom wall 34. And a connecting member 32 (hereinafter, referred to as a connecting member) that stands up, and a reinforcing member holding member 33 that is connected to a rear portion of the bottom wall 34. As shown in FIG. 4, the connector terminal 3 is configured such that the connection piece 32 penetrates through the insulating tape 25 of the tape electric wire 2, and
Are curled from both sides so that they can be held together. The distal end portion 32a and the bottom portion 32b of the curled connection piece 32 are sandwiched between the rectangular conductors 21 to 24, respectively, so that the connector terminal 3 is connected to the rectangular conductor 2
1 to 24, respectively. At this time, the reinforcing member sandwiching piece 33 is simultaneously connected to the insulating tape 25 and the reinforcing tape 26 of the tape electric wire 2 by a crimping machine (pressing machine) as shown in FIGS. 1 and 3. Are crimped so as to penetrate them together and embrace them from both sides.

Here, the production of the tape wire with terminal 1 is as follows.
First, as shown in FIG. 2, a reinforcing tape 26 coated with a thermoplastic adhesive on one side is positioned on the tape wire 2 and then bonded and fixed on the tape wire 2 by a hot press (not shown). The positioning of the reinforcing tape 26 on the tape electric wire 2 is such that the end surface of the reinforcing tape 26 is positioned at a predetermined distance Y from the end surface of the tape electric wire 2. At this time, the end face of the reinforcing tape 26 is located between the caulking position of the connecting piece 32 of the connector terminal 3 and the caulking position of the reinforcing member sandwiching piece 33. In addition, reinforcement tape 2
The reason why the reinforcing tape 26 is not attached to the connection piece caulking position of the tape wire 2 is that the reinforcing tape 26 is affixed to the connection piece caulking position of the tape wire 2.
When the reinforcing tape 26 is sandwiched together with 6, the degree of crimping is reduced by the thickness of the crimped portion, and the contact pressure of the crimped portion (the contact pressure of the connection piece 32 with each of the rectangular conductors 21 to 24) is reduced. This is because Similarly, when the thickness of the crimped portion of the connection piece 32 is increased, if the resin material such as the reinforcing tape 26 is softened by the heat generated in the crimped portion, the thickness of the crimped portion is increased. The tightened portion is loosened, the contact pressure of the swaged portion is reduced, and the contact resistance (fusing resistance) of the swaged portion is increased, so that more heat is generated.

Next, as shown in FIG. 4, the connecting pieces 32 are respectively crimped to the rectangular conductors 21 to 24 of the tape electric wire 2 by a crimping machine to make electrical connection, and reinforced as shown in FIG. The member sandwiching piece 32 penetrates through the tape electric wire 2 and the reinforcing tape 26 and is embraced from both sides to be mechanically fixed. Thereby, the tape wire with terminal 1 is completed.

Thereafter, locking lances (not shown) of the connector terminals 3 of the tape wire 1 with terminals are sequentially inserted into and engaged with stepped locking portions (not shown) in the connector housing 4, respectively. In this way, the connector terminals 3 of the tape wire with terminals 1 are sequentially inserted into the connector housing 4 respectively. When this terminal is inserted, the tape wire 2
In contrast, since the portion to which the reinforcing tape 26 is attached is a rigid portion, there is an effect that the workability of the manual or automatic terminal insertion operation is improved. As described above, the wire harness 10 is manufactured.

As a result, even if a pull-out force is generated in the tape wire 2, the external force is uniformly dispersed throughout the tape wire 2 by the portion where the reinforcing tape 26 is bonded, and the flat conductors 21 to 24 and the connector terminals 3 No external force acts on the caulked portion where the connection piece 32 is electrically connected. For this reason, it is possible to prevent the occurrence of electrical connection failure due to deformation or breakage (such as disconnection) of the caulked portion.

In this embodiment, the connecting pieces 32 of the connector terminal 3 are electrically connected to the rectangular conductors 21 to 24, respectively, and at the same time, the reinforcing member sandwiching piece 33 behind the connecting pieces 32 is a tape electric wire. After being penetrated through the insulating tape 25 and the reinforcing tape 26 of FIG. 2, it is mechanically fixed so as to embrace it from both sides, but as shown in FIG. Through the insulation tape 25 and the tape wire 2 and the reinforcing tape 2
It is also possible to adopt a configuration in which the pinching projection 27a of 7 is held and mechanically fixed from both sides. The pinching protrusions 27a of the reinforcing tape 27 are arranged at the pitch of the connector terminals 3,
That is, it is provided at a caulking position of each reinforcing member sandwiching piece 33. Also in this case, similarly to the present embodiment, the tape wire 2
The connector terminal 3 is crimped to a to form a tape wire 1a with a terminal, and the connector terminal 3 of the tape wire 1a with a terminal is inserted into the connector housing 4 to form a wire harness 10a. With this configuration, even if the pull-out external force acts on the tape electric wire 2 in the direction of the arrow X, the external force is applied to all the holding portions of the reinforcing member sandwiching piece 33 between the tape electric wire 2 and the reinforcing tape 26, so that the external force is applied. The external force hardly acts on the crimped portion of the connection piece 32 to the tape wire 2, so that it is possible to prevent the occurrence of electrical connection failure due to deformation or breakage (such as disconnection) of the crimped portion. It is. Moreover, each reinforcing member sandwiching piece 3
3 does not need to penetrate the reinforcing tape 26 of the above-described embodiment, and accordingly, the force required for clamping (caulking) is reduced, and the tape wire 2 and the clamping protrusion 27a of the reinforcing member clamping piece 33 are reduced. Can be easily carried out.

In the present embodiment, the tape electric wire 2 is
Although the four rectangular conductors 21 to 24 arranged in parallel are bonded with the insulating tape 25 from above and below, the present invention is not limited to this, and an insulating resin material (for example, PV
C; polyvinyl chloride, PE; polyethylene, etc.). Further, the number of rectangular conductors may be one or plural.

Further, in this embodiment, the connector terminals 3
The connection between the rectangular conductors 21 to 24 was performed by crimping (caulking). However, the connection is not limited to this, and the connection between the connector terminal 3 and the rectangular conductors 21 to 24 was performed by solder welding, resistance welding, and super welding, respectively. It may be performed by sonic welding or the like.

Further, in the present embodiment, the rectangular conductors 21 to 24 having a rectangular cross section are used as the parallel wiring of the tape electric wire 2. However, the present invention is not limited to this, and a conductor having a circular cross section or an elliptical cross section may be used. .

[0025]

As described above, according to the first and fourth aspects of the present invention, the connecting terminal of the connector terminal is crimped to penetrate and hold the tape wire, and the connecting terminal of the connector terminal is connected. Since the reinforcing member sandwiching piece continuously provided at the rear of the piece is crimped to hold the tape wire and the reinforcing member, it is possible to secure a good electrical connection between the tape wire and the connector terminal, and Even when an external force acts on the taper wire and the reinforcing member of the reinforcing member, the external force acts on the holding portion between the reinforcing member and the reinforcing member, so that the external force hardly acts on the electrical connection portion of the connector terminal. It is possible to prevent the occurrence of electrical connection failure due to deformation or breakage (such as disconnection) of the semiconductor device.

According to the second aspect of the present invention, since the reinforcing member holding piece does not need to penetrate the reinforcing member, the reinforcing member holding piece can be easily held between the tape wire and the holding projection. it can.

Further, according to the third aspect, since the portion where the reinforcing tape is stuck to the tape electric wire is a rigid portion, the workability when manually or automatically inserting the connector terminal into the connector housing is provided. Can be improved.
