Therefore, when connecting the connecting connector to the fixed connector, the base end side connecting portion of the connecting connector is connected to the fixed connecting portion of the fixed connector. At this time, the distal end of the fixed pin of the fixed connector is connected to the proximal end of the connection pin of the connection connector. For this reason, the cable of this connection connector is connected to the fixed wiring portion.

In this state, when the next connector is connected to the first connector already connected, the proximal connector of the next connector is connected to the distal connector of the first connector. At this time, the distal end of the connection pin of the first connection connector is connected to the base end of the connection pin of the next connection connector. Therefore, the cable of the next connector is connected to the fixed wiring portion.

In this manner, another connecting connector can be connected to the connecting connector one after another. The cables of the connected connectors are all connected to the fixed wiring portion.

Further, the connector with a cable according to claim 2 is

As shown in FIG. 1, the connecting connector 16 includes a proximal connecting portion 26 connected to the fixed connecting portion 18 and a distal connecting portion 28 formed on the opposite side to the base connecting portion 26. A connection pin 30 connected to the fixed pin 24 of the fixed coupling portion 18;
30 and a cable 32 connected thereto. And FIG.
As shown in FIG.
Are formed by interposing the cable 32 and assembling it with the main body 34 on which the is formed. The material of the connecting connector 16 is the same as that of the fixed connector 14. The main body 34 and the base end connecting portion 26 are desirably made of a synthetic resin. ), And the surface is desirably plated with a noble metal such as copper or silver.

The proximal coupling portion 26 is shaped and sized to be fitted into and fixed to the fixed coupling portion 18 of the fixed connector 14. That is, the base-side coupling portion 26 and the fixed coupling portion 18 can be fixed by fitting each other in a male and female shape (irregular shape). As shown in FIG. 4, a claw 26a for engaging with the main body 34 of the connecting connector 16 is formed on the base end side connecting portion 26 opposite to the fixed connecting portion 18. This nail 26a
The main body 34 and the base-side coupling portion 26 are combined and integrated by locking the engaging holes (not shown) of the main body 34 facing each other. Further, a base portion 30a, which is a base portion of the connection pin 30, is provided at each position of the base side coupling portion 26 facing the fixing pin 24. The proximal-side coupling portion 26 and the proximal-side portion 30a of the connection pin 30 are integrally formed by, for example, a molding method. Then, the base side connecting portion 26 is fitted into the fixed connecting portion 18 and connected thereto, so that the connection pin
The proximal end portion 30a of 30 is connected to the distal end portion 24b of the fixing pin 24.

The distal connecting portion 28 is a rectangular recess formed facing the opposite side of the proximal connecting portion 26. here,
The distal end side connection portion 28 has the same shape and size as the fixed connection portion 18. Therefore, as shown in FIGS. 1 and 2, it is possible to connect the proximal-side connecting portion 26 of the other connecting connector 16 to the distal-side connecting portion 28 of the connecting connector 16, and a plurality of connecting connectors 16. 16 can be connected consecutively. Further, at a position facing the proximal end portion 30a of the connection pin 30 of the main body 34, a distal end portion 30 which is a distal end of the connection pin 30 is provided.
b is provided. Tip portion 30b of this connection pin 30
Is exposed inside the distal-end-side connecting portion 28. Note that the main body 34 and the distal end portion 30b of the connection pin 30 are integrally formed by, for example, a molding method.

Further, as shown in FIG. 4, the opposing portions of the proximal end portion 30a and the distal end portion 30b of the connection pin 30 have a bifurcated pointed shape. For this reason, when connecting the proximal-side connecting portion 26 to the main body 34, the cable 32 is sandwiched between the proximal-side portion 30a and the distal-side portion 30b of the connection pin 30 and pressed against each other, so that these proximal-side portions 30a The opposing portion of the front end portion 30b breaks the vinyl coating of the cable 32 and comes into contact with the inner cable core 36 to conduct electricity. As a result, the base end portion 30a and the distal end portion 30b of the connection pin 30 conduct, and the connection pin 30 and the cable 32 are connected. Moreover, the cable 32 is fixed to the connecting connector 16 so as not to easily fall off.

Further, both sides of the main body 34, that is, a fixed connector
On both surfaces continuous with the surface having the 14 locking holes 20, locking claws 40 constituting a locking mechanism 38 together with the locking holes 20 are provided. As shown in FIG. 5, a through hole is formed in a base end portion 40a of the locking claw 40, and the locking claw 40 is rotatably attached to the main body 34 by a locking pin 42. Then, the tip 40b of the locking claw 40
Has a shape bent toward the locking hole 20.
Accordingly, the distal end portion 40b of the locking claw 40 is locked in the locking hole 20 while the connecting connector 16 is connected to the fixed connector 14, whereby the connecting connector 16 is locked with respect to the fixed connector 14. Also, by releasing the locking of the locking claw 40,
The connection connector 16 can be detached from the fixed connector 14.

Further, a connecting portion on the tip side of the locking claw 40 of the main body 34
A locking hole 44 is formed on the 28 side. This locking hole 44
Has the same shape and size as the locking hole 20 of the fixed connector 14. Therefore, when another connecting connector 16 is connected to this connecting connector 16, the locking claw 40 is locked in the locking hole 44, and the connecting connectors 16 can be locked by the lock mechanism 38.

The procedure for using the above-described connector with cable 10 will be described below.

As shown in FIG. 1, the proximal connector 26 of the connecting connector 16 is fitted into the fixed connector 18 of the fixed connector 14 fixed to the fixed wiring portion 12. At this time, fixed connector 14
Of the fixing pin 24 and the connecting pin of the connector 16
The base 30 is connected to the base portion 30a. Thereby, the wiring pattern 12b of the fixed wiring portion 12 and the cable 32 are conducted.

Then, the locking claw 40 of the connecting connector 16 is locked in the locking hole 20 of the fixed connector 14. As a result, even if the connecting connector 16 is pulled as it is,
The connection can be strengthened without falling off.

Further, as shown in FIG. 2, a proximal-side connecting portion 26 of another connecting connector 16 can be fitted into a distal-side connecting portion 28 of this connecting connector 16. With this insertion,
The connection pins 30 of each connection connector 16 are connected. For this reason, the wiring pattern 12b of the fixed wiring portion 12 and the cables 32 of each connection connector 16 are conducted.

Then, the locking claws 40 of the newly connected connector 16 are engaged with the locking holes 44 of the already connected connector 16.
To lock. Thus, even if the connecting connector 16 is pulled as it is, it does not come off, and the connection can be strengthened.

As described above, the proximal connecting portion 26 of the other connecting connector 16 is connected to the distal connecting portion 28 of the connecting connector 16,
By connecting another connecting connector 16 to this connecting connector 16 one after another, a plurality of connecting connectors 16 can be connected to one fixed connector 14 continuously.
Then, by transmitting a signal from the fixed wiring unit 12 in this state, the same signal can be transmitted to all the connected cables 32.

On the other hand, when removing the connecting connector 16,
The locking claw 40 may be removed from the locking holes 20, 44, and the coupling connector 16 may be pulled.

As described above, according to the connector with cable 10 of the present embodiment, the connecting connectors 16 can be connected one after another to the fixed connecting portions 18 of the fixed connector 14 fixed to the fixed wiring portion 12, so that the fixed wiring When a plurality of cables 32 are connected to the unit 12, only one fixed connector 14 needs to be attached to the fixed wiring unit 12. For this reason, the space required for mounting the fixed connector 14 on the fixed wiring portion 12 can be reduced to the size of one fixed connector 14, and the mounting space can be made more efficient. In addition, since the fixed connecting portion 18 of the fixed connector 14 faces the outside of the fixed wiring portion 12, even if a plurality of connecting connectors 16 are connected, the vertical interval of the fixed wiring portion 12 is kept higher than the height of one fixed connector 14. It can be minimized and minimized. As a result, the fixed wiring section 12 can be reduced in size and weight.

The connector 10 with a cable according to the present embodiment
According to the above, since the lock mechanism 38 is provided, each connector
Connection between 14, 16 can be ensured. Particularly, when a large number of connection connectors 16 are connected, a large load is generated at the connection portion between the connectors 14 and 16, and the contact resistance between the connection pins 30 and the fixed pins 24 tends to vary, but the locking mechanism 38 By locking the contact, stable contact resistance can be maintained. Thereby, the contact reliability can be improved, and the reliability of signal transmission from the fixed wiring section 12 to each cable 32 can be improved.

Further, since the locking claw 40 and the locking holes 20 and 44 are used as the locking mechanism 38, it is possible to securely lock and release the locking with a simple structure. Also, locking claw
Since the lock is completed by fitting the 40 into the locking holes 20, 44, the user can easily understand whether or not the lock mechanism 38 is in the locked state. Therefore, the operability is good.

In the connecting connector 16 of the present embodiment,
When connecting the main body 34 and the
Since the cable 32 is sandwiched between the distal end portion 30b and the proximal end portion 30a of the 30 for conduction, the connection between the cable 32 and the connection connector 16 can be easily performed.

The above embodiment is an example of a preferred embodiment of the present invention, but the present invention is not limited to this, and various modifications can be made without departing from the spirit of the present invention. For example, in the above-described embodiment, since the fixed coupling portion 18 of the fixed connector 14 is directed to the outside of the fixed wiring portion 12, the connection direction of the connection connector 16 is directed to the outside of the fixed wiring portion 12, but this is not a limitation. Instead, as shown in FIG. 6, the connecting direction of the connecting connector 16 may be directed to the vertical direction of the fixed wiring portion 12 with the fixed connecting portion 18 of the fixed connector 14 facing the vertical direction of the fixed wiring portion 12. In this case, for example, another member is arranged outside the fixed wiring portion 12 and the connecting connector 16
Can be connected in the vertical direction of the fixed wiring portion 12 even when the connection cannot be continuously performed.

In each of the embodiments described above, the lock mechanism 38 is provided. However, the present invention is not limited to this, and the lock mechanism 38 may not be provided. In particular, when the number of the connection connectors 16 is small, a load is hardly generated at the connection portion between the connectors 14 and 16, so that even if the lock mechanism 38 is not provided, the contact resistance does not easily vary.

[0037]

As described above, according to the connector with a cable according to the present invention, when a plurality of cables are connected to the fixed wiring portion, only one fixed connector needs to be attached to the fixed wiring portion. For this reason, the space required to mount the fixed connector on the fixed wiring portion can be reduced to the size of one fixed connector, and the mounting space can be made more efficient. In addition, since the fixed connecting portion of the fixed connector faces the outside of the fixed wiring portion, even if a plurality of connecting connectors are connected, the vertical spacing of the fixed wiring portion is suppressed to the height of one fixed connector and minimized. Can be achieved. Thereby, the size and weight of the fixed wiring portion can be reduced.

According to the connector with the cable according to the second aspect of the present invention, the connecting portion between the fixed connecting portion and the proximal connecting portion, and the connecting portion between the proximal connecting portion and the distal connecting portion are formed. ,
Since the respective lock mechanisms are formed, when the connectors are connected to each other, the lock mechanisms operate to ensure the connection between the connectors. In addition, when a large number of connectors are connected, a large load is applied to the connecting portions of the connectors, and the contact resistance between the connection pins and the fixed pins is likely to vary. Resistance can be maintained. Thereby, the contact reliability can be improved, and the reliability of signal transmission from the fixed wiring portion to each cable can be improved.
