Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flat cable, a ribbon electric wire, an FPC (Flexible P
The present invention relates to a flat wiring material connector for electrically connecting a flat wiring material such as a rinted circuit to a circuit board or the like.

[0002]

2. Description of the Related Art Conventionally, a connector (first connector) for a board, in which a plurality of terminals are accommodated in parallel, is mounted on a circuit board, and a mating connector (a first connector) is attached to an end portion of a flat wiring material such as a flat cable. A flat wiring material connector in which a flat wiring material is connected to a circuit board by mounting a second connector) and fitting both connectors together is generally known.

In such a flat wiring member connector, the flat wiring member has a terminal portion treated so that a conductor is exposed to the outside.
It is supported on a plate-like support member provided on the connector. Then, when the two connectors are fitted together, the terminal portion of the flat wiring material is inserted into the board connector together with the support member, and the terminals are pressed into contact with the respective conductors. And the pattern on the circuit board are electrically connected.

The housing of each connector is provided with a locking portion, and when both connectors are completely engaged, the locking portions engage with each other to lock both connectors. It has become so.

[0005]

In the structure of such a conventional connector for flat wiring members, the insertion depth when the two connectors are fitted (the insertion depth of the flat wiring member (support member) with respect to the first connector). The change in the fitting force, that is, the fitting force characteristic is a two-stage peak type characteristic as shown in FIG. That is, when both connectors start to be fitted, first, the terminal comes into pressure contact with the conductor portion of the flat wiring material, so that the fitting force sharply increases and an initial peak (shown in the drawing) occurs, and the fitting force is slightly reduced. After that, when the locking portions of both connectors are engaged with each other, the fitting force increases again, and a second peak (shown in the figure) occurs.

Therefore, there is a poor fitting feeling called a so-called two-stage feeling in which a position having a large fitting force is generated twice independently as the two connectors are fitted. It may be misunderstood that the two connectors are completely fitted at the peak position. In such a case, there is a problem that the two connectors are in an incompletely fitted state, which may cause disconnection or the like later.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and eliminates a so-called two-stage feeling of poor fitting feeling, so that connectors can be more securely fitted. It is intended to be.

[0008]

In order to solve the above-mentioned problems, a flat wiring member according to the present invention comprises a first connector for accommodating a terminal and a second connector mounted on an end portion of the flat wiring member.
The flat wiring member is inserted into the first connector by fitting the two connectors, and the terminal is pressed into contact with the conductor portion of the flat wiring member, and the engaging portions formed on both connectors are engaged with each other. In a flat wiring connector that locks both connectors together, the peak of the fitting force of both connectors due to the terminal being pressed against the conductor portion and the peak of the same fitting force due to the engagement of the locking portions, Each connector is formed so as to occur at substantially the same position at the insertion depth position of the flat wiring member with respect to the first connector (claim 1).

According to such a connector for a flat wiring member, only one peak of the fitting force generated when the two connectors are fitted, or two peaks are generated continuously even if there are two peaks. . Therefore, if the two connectors are normally fitted, the peak of these fitting forces can be perceived as one, and so-called two-stage feeling can be eliminated. In addition, as described above, the phrase “occurs at the same position at the insertion depth position of the flat wiring member with respect to the first connector” as described above means that there is only one peak of the fitting force generated when both connectors are fitted. Or a position where two peaks occur continuously even if there are two peaks.

As a specific configuration, for example, a plate-shaped support member is provided on the second connector, and a terminal portion of the flat wiring member is supported on the support member. In the connector of the type in which the wiring member is inserted into the first connector, the distal end portion of the support member in the insertion direction is such that the terminal is not pressed against the conductor portion until a predetermined insertion depth position of the support member. It is preferable to form a thin plate portion having a smaller wall thickness than the rear portion thereof (claim 2).

According to this structure, at the initial stage of connector fitting, the terminal is in a non-pressed state with respect to the conductor portion, and when the terminal reaches a predetermined insertion depth position, the terminal is in a press-contact state with the conductor portion. Therefore, the peak of the fitting force due to the terminal being pressed against the conductor portion occurs at a position where the flat wiring member is inserted deeper. As a result, the peak of the fitting force of the two connectors due to the terminal being pressed against the conductor portion and the peak of the same fitting force due to the engagement of the locking portions occur at a position (insertion depth position) closer to each other. It will be.

Insert each into 6B. At this time, the guide 66 of the holder 50b is inserted into the guide grooves 28 formed in the insertion ports 26A and 26B.
The connector C22 is inserted into the outlets 26A and 26A while guiding along
6B.

By doing so, the structure shown in FIGS.
(B) → As shown in FIGS. 5 (b) and 12 (c), the housing 50a (body portion 52) of each connector C22 fits into the hood 27 of the connector C14. Also,
As the connector C22 is inserted, the pair of locking pieces 40 in the connector C14 are pushed out to the locking portions 60a formed in the holder 50b, and the holder 50b is
22, the hooks 40a of the locking pieces 40 are engaged with the locking portions 60a of the holder 50b, respectively. It will be locked. The locking portion 60a of the holder 50b is formed in a substantially trapezoidal shape in a plan view that tapers from the base end portion to the tip end portion. Therefore, the lock state is a so-called semi-lock state, and the connector C22 Is pulled in the pulling-out direction with a certain force or more, the locked state is released and the connector C22 can be removed from the connector C14.

When the connector C22 is fitted to the connector C14 in this manner, the exposed portion of the conductor 2 of the cable 17 and the holder 50b are connected to the connection portion 2 of the connector C14.
1A and 21B, respectively, and more specifically, the conductor 2 and the like are inserted between the connecting flexure piece 24a and the bottom 24d of each terminal 24, and each terminal 2 is connected to each conductor 2 of the cable 17.

Is connected to the circuit of the circuit board P of the CD player 14 via the terminal 24, and the cable 15 of the CD player 14 connected to the rear side of the connector C14.
And the corresponding ones of the conductors 2 of the cable 17 are relay-connected by the terminals 24.

By connecting the cables 15, 17, and 19 to the connectors of the players and the like arranged vertically next to each other, each player 1 is connected to the main board 12.
4, 16, and 18 can be connected in a chain.

As described above, in this audio unit, the main board 12 and the players 14, 16, and 18 arranged vertically are electrically connected in a chain by the cable 15 and the like provided on each player 14. As described above, the cables 15, 17, 19 of the respective players 14 and the like are provided.

Connectors C12, C14, C16, and C18 are provided, and as a result, the connection work of the cable 15 and the like can be performed in a divided manner. Alternatively, the cables 15, 17, and 19 can be easily connected to the players 14 and the like. That is, according to this configuration, the connection work of the cable 15 and the like can be performed in a divided manner, for example, after connecting the connector C22 on the one side of the cable 15 and the like, and then connecting the connector C22 on the other side. ,
The operating force required for one connection operation of the connector C22 is reduced. Therefore, even when the number of the conductors 2 in the cable 15 or the like is extremely large, the cable 15 or the like can be easily and securely connected by performing the connection work by dividing in this manner.

Moreover, in this audio unit, the connector C22 and the connectors C12, C14, C16, C1
8 and the connector C22 as described above.
Since the thin plate portion 60b is formed at the distal end portion (the distal end portion of the mating surface 60) of the holder 50b, the poor fitting feeling referred to as a so-called two-stage feeling as in the related art is eliminated. There is an effect that the connectors can be connected more reliably. That is, in the connector C22, the thin plate portion 6 is attached to the tip of the holder 50b.
As a result, the connector C22 and the connector C14 are in the initial stage of fitting with each other as shown in FIGS.
As shown in (a), even if the distal end portion of the connector C22 is inserted into the connector C14, since the plate thickness of the holder 50b is thin, the connecting flexure piece 24a is connected to the conductor 2 of the cable 17.
Is not pressed, and the connection bending piece 24a is pressed against the conductor 2 only when the holder 50b is further inserted into the connector C14 from this state. Therefore, the fitting force characteristics between the connector C22 and the connector C14 are as shown in FIG.
As shown in FIG. 5, the peak of the fitting force (shown in the figure) due to the connection bending piece 24a being pressed against the conductor 2 occurs at a position where the cable 17 (holder 50b) is inserted deeper into the connector C14. As a result, the peak of the fitting force and the peak (in the figure) of the fitting force due to the engagement of the locking piece 40 (the hook 40a) with the holder 50b (the locking portion 60a) are as shown in FIG. Holder 50
It occurs almost continuously with the insertion of b. Thus, if the connectors C22 and C14 are normally fitted to each other, the peak of the fitting force can be perceived as one, and the poor fitting feeling called the so-called two-stage feeling is reduced. Will be resolved. Therefore, as in the prior art, the operator can use both connectors C22 and C22 at the first peak position.
It is not misunderstood that the connector 14 has been completely fitted, so that the connectors can be securely connected to each other.

In this embodiment, the holder 50b
The thin plate portion 60b is formed at the distal end of the connecting piece, and in the fitting force characteristic, the peak position of the fitting force due to the press-contact of the connecting flexure piece 24a to the conductor 2 and the fitting due to the engagement of the locking piece 40 with the holder 50b. Although the peak position of the resultant force is made to approach, for example, instead of providing the thin plate portion 60b in the holder 50b, the connecting flexure piece 24a of each terminal 24 is provided on the back side of the connector C14, so that the both peak positions can be adjusted. You may make it approach.

In each of the above embodiments, the present invention is applied to an electrical connection structure of a vehicle audio unit. However, the present invention is of course applicable to other electrical connection structures of an electric unit and the like. is there.

In the above embodiment, the flat cables 15, 17, and 19 are used as the flat wiring material. However, the flat wiring material is not limited to the flat cable, but may be a ribbon electric wire, a flexible printed cable (FPC), or the like.
Other flat wiring materials such as ircuit) may be used.

In a flat wiring material connector in which a flat wiring material is inserted into the first connector and brought into contact with the terminal, a peak of a fitting force between the two connectors due to the terminal being pressed against a conductor portion of the flat wiring material;
Each connector is configured such that the peak of the same fitting force due to the engagement of the locking portions occurs at substantially the same position at the insertion depth position of the flat wiring member (second connector) with respect to the first connector. When the two connectors are normally fitted with each other, the peak of these fitting forces can be sensed as one, so that the poor feeling of fitting called the so-called two-step feeling is improved. Can be eliminated. Therefore, it is possible to effectively prevent the two connectors from being in an incompletely fitted state due to the worker erroneously setting the peak position of the fitting force, and as a result, the connectors can be more reliably connected to each other. become.
