Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connection structure of a connector for branching a twisted pair wire used for a signal transmission bus line of an electric device such as an automobile.

[0002]

2. Description of the Related Art In recent years, signal transmission used for electric signals transmitted to a control printed circuit board on which electronic parts or ICs (integrated circuits) incorporated in an electric device of a vehicle such as a car navigation system are mounted. A twisted pair wire is used for the bus line for noise reduction.
Conventionally, in order to branch a twisted pair line for a trunk line as a bus line used for such an in-vehicle LAN (Local Area Network) into a twisted pair line for a branch line, a branch connection is made as shown in FIGS. Structures are known.

[0005] The branch structure shown in FIG. 15 has a branch wire twisted pair wire whose end is also exposed to a core wire 2a exposed by cutting and removing only the covering material at an intermediate position of the trunk twisted pair wire 2. The three core wires 3a are connected by caulking the intermediate joint terminal 41. The procedure for performing the branch connection will be described. First, the twist at the intermediate position of the trunk twisted pair wire 2 before connection is partially returned, and the insulating coating at that portion is removed. Then, the exposed core wires 2 of the twisted pair wire 2 for the trunk line and the twisted pair wire 3 for the branch line are respectively exposed.
After a and 3a are crimped and connected by the intermediate joint terminal 41, insulation protection is performed by wrapping an insulating tape (not shown) around the connection portion. After that, the connection is completed by untwisting.

A branch connection connector 51 shown in FIG. 16 is disclosed in Japanese Patent Laid-Open No. 4-342969. This forms a groove 53 for holding the trunk twisted pair wire 2 in the connecting connector main body 52, and the U-shaped terminal 5 connected to the base end of the branch twisted pair wire 3.
4 and 54 are rotatably supported on both sides of the connector main body so as to be orthogonal to the twisted pair wire 2 for the trunk line, and by rotating the U-shaped terminals 54 and 54,
The terminal inner peripheral edge of the V-shaped terminal 54 is cut into the covering material of the twisted pair wire 2 for the trunk line, and the core wire is brought into contact with the core wire to conduct branch connection.

[0005]

However, FIG.
In the case of a branch structure, the twist of the twisted pair wire for the trunk line is returned, the insulating coating on that part is removed, the insulating coating on the tip of the twisted pair wire for the branch line is removed, and each is crimped with an intermediate joint terminal and crimped Insulate with an insulating tape so that the twisted pair wires do not short-circuit, and return the twist. In such a process, there is a problem in that the number of connection steps is large, and the connection between the twisted pair wire for the trunk line and the twisted pair wire for the branch line cannot be easily and reliably performed.

In the case of the branch structure shown in FIG. 16, the covering material at the tip of the twisted pair wire for the branch line is peeled off in advance.
It is necessary to crimp the U-shaped terminal to the core wire, and the structure of the connector for connection is complicated, and the workability of connection cannot be said to be good. In addition, the width dimension of the connection connector body, that is, the length of the groove portion is one of the twist pitch of the twisted pair wire for the trunk line.
/ 2, and a connector having a different width must be newly prepared in order to apply to a connector having a different twist pitch. Furthermore, since the branch twisted pair wire can be branched and connected only in a direction perpendicular to the trunk twisted pair wire, there is a problem that it is necessary to devise connection and fixing in places where the wiring space for vehicles and the like is limited. there were.

SUMMARY OF THE INVENTION An object of the present invention is to provide a connection structure of a branch connector which has a simple structure and is capable of easily branch connection of a twisted pair wire for a trunk line and a twisted pair wire for a branch line.

[0008]

SUMMARY OF THE INVENTION In order to solve this problem, a connection structure for a branch connector according to the present invention is provided on an insulated connector main body which holds an intermediate position of a twisted pair wire for a trunk line and an end of the twisted pair wire for a branch line. A main line twisted pair line pressure contact portion and a branch line twisted pair line pressure contact portion whose pressure contact directions are opposed to each other are provided in connection with each other, and a pair of pressure contact terminals are provided in parallel inside the connector main body. At one end, a press-contact blade to which an intermediate position of the twisted pair wire for trunk is connected, and at the other end, a press-contact blade to be connected to an end of the twisted pair wire for branch wire, and the main wire twisted pair wire press-contact portion is used for main wire. A lid to which the twisted pair wire is fixedly attached and a lid to which the twisted pair wire for branch wire is fixedly attached are attached to the press-contact portion of the twisted pair wire for branch line. It is an Abstract that end in the middle of the main twisted pair line position and branch twisted pair line is electrically connected by.

According to the connection structure for a branch connector according to the present invention having the above structure, the insulating connector main body holding both twisted pair wires is provided with the pair of press contact terminals having the press contact blades. The connection can be made without exposing the core wire by stripping the covering material of the wire and the twisted pair wire for the branch wire. In addition, since the main wire twisted pair wire pressure contact portion and the branch wire twisted pair wire pressure contact portion whose pressure contact directions are opposed to each other are provided in a connected manner, when one of the twisted pair wires is press-connected to the other, the other twisted pair wire interferes. Workability is improved because it does not interfere.
Also, in the case of crimping connection, both twisted pair wire crimping parts,
By attaching a cover to which the twisted pair wire for trunk is fixed and a cover to be attached with the twisted pair wire for branch fixed, the workability of branch connection is improved.

Further, since the connector can be constituted by a connector body having a simple shape provided with a press contact terminal and a lid, manufacturing costs can be reduced. Further, with such a configuration, it can be used for other than the connection between the twisted pair wires. An electrical connection in which a trunk twisted pair wire or a branching twisted pair wire is connected to one press-connecting portion and a resistor or the like for setting a terminating resistance of the twisted pair wire is mounted to the other press-connecting portion, for example. By press-connecting the components, it is possible to easily add an element such as a terminating resistor to the twisted pair wire.

In this case, the connecting portion for connecting the main wire twisted pair wire pressure contact portion and the branch wire twisted pair wire pressure contact portion whose pressure contact directions are opposed to each other is orthogonal to the pressure contact direction and the main wire twisted pair wire pressure contact portion and the branch wire. If it is provided so as to be connected to the twisted pair wire press-connecting portion, the press-connecting work can be performed in a small press-connecting connection space, so that workability in a narrow wiring place is improved.

Further, if the connector body is constituted by a pair of divided bodies, it is possible to assemble the pressure contact terminal by mounting the pressure contact terminal therein without integrally forming the connector body with the pressure contact terminal provided inside. Since it becomes possible, replacement of the press contact blade after assembling can be performed.

If the connector body is provided with a fixing portion for fixing the twisted pair wire for the trunk line and the twisted pair wire for the branch line, the twisted pair wire can be temporarily fixed at the time of the press-connecting operation. The workability of the crimp connection is further improved. At this time, if a clamp portion that opens and closes resiliently is provided at the distal end portion of the fixing portion, the branch connector connected by pressure is connected to a fixing hole formed in another member where the wiring is arranged. It can be engaged and fixed. Furthermore, if the member for preventing detachment is attached to the end of the end of the twisted pair wire for branch line, detachment from the press contact portion is surely prevented even if the member is pulled.

Furthermore, a resistance element such as a chip resistor used as impedance matching when a twisted pair wire having a different circuit impedance is connected between a pair of press contact terminals provided in the connector body, and noise reduction in a transmission line of the twisted pair wire. If the configuration is such that the connection is made via an electric element such as a chip capacitor for such a purpose, it is possible to add such an electric element without adding a member or a mounting space for separately adding the electric element to the twisted pair circuit. can do.

According to the branch connector 1 or the branch connector 21 having such a configuration, it can be used for other than the connection between the twisted pair wires. For example, using the branch connector 21 of FIGS. 6 and 7, as shown in FIG. 8, the twisted pair wire 3 for the branch wire is connected to the press-contact portion 26 b to be press-connected, and the press-contact portion 26 a to be press-connected to the other.

Further, it is also possible to provide an electric element between a pair of press contact terminals provided on the above-mentioned connector main body and connect the press contact terminals via the electric element. As the electric element, for example, a resistance element such as a chip resistor used as impedance matching when a twisted pair wire having a different circuit impedance is connected, and a noise filter element such as a chip capacitor for reducing noise of a transmission line of the twisted pair wire are used. is there. In order to add such an element between the press-connecting terminals, before cutting the connector body from the carrier material 9 during the manufacturing process of the press-connecting terminals 4 and 5 as shown in FIG. It becomes possible by soldering or welding 31 and connecting between crimp terminals 4 and 5. If the electric element is connected between the press contact terminals and built into the connector body in this way, it is possible to add such an electric element to the circuit of the twisted pair wire without adding a member or a mounting space. can do.

As a preventive measure in the event that such a branch connector is subjected to a stress such that it is pulled after the crimping connection, a pull-out preventing member 32 is provided at the end of the end of the branch twisted pair wire 2 as shown in FIG. May be worn. The detachment from the press contact portion is reliably prevented. As the detachment preventing member 32, for example, a metal plate material is used, and a cut-and-raised piece 32a is formed to be bent substantially from the center thereof, and crimping pieces 32b are provided on the right and left by slightly bending inward.
The twisted pair wire for branch line 2 is placed on the placing portion 32c and fixed by crimping. After such a detachment preventing member 32 is crimped and fixed to the end of the twisted pair wire 3 for branch lines, for example, FIG.
As shown in (1), if the branch connector 1 is press-connected, it is possible to prevent the branch wire 1 from coming off from the press-contact portion even if stress is applied to pull the twisted pair wire 3 for branch lines.

In order to improve the workability of the crimp connection, a fixing portion 36a for fixing the twisted pair wire 2 for the trunk line and the twisted pair wire 3 for the branch line to the connector body 36 as shown in FIG. It is good to provide near. The fixing portion 36a is formed integrally with the connector main body 36, and fixes the twisted pair wire so that the twisted pair wire is elastically sandwiched between the fixing pieces 36b, 36b so that the twisted pair wire does not come off easily. Such a fixing part 36
If a is provided, the twisted pair wire can be temporarily fixed at the time of the press-connecting operation, so that the press-connecting operation is easy.

Further, in this case, as shown in FIG. 14 (a), clamp portions 36c, 36c which can be opened and closed resiliently may be provided at the tip of the fixed portion 36a. The clamp portion provided in this manner is easily fixed by engaging with a fixing hole 40a formed in another member 40 (for example, a body of an automobile, etc.) where the branch connector connected by pressure connection is arranged. Work can be done. In this case, as shown in FIG.
A clamp may be provided so that c is interchanged. The clamp can be more easily inserted into and engaged with the fixing hole 40a.

Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments at all, and it goes without saying that the present invention can be implemented in various modes without departing from the gist of the present invention. For example, a bifurcated locking piece for fixing the lid used for the pressure connection is provided in such a position at such a position, and the lid is not limited to such a shape, but is required. Any structure may be used as long as the cover can be easily attached to the connector body without being detached. Furthermore, it goes without saying that the connector main body and the lid body may not be formed as separate bodies, but may be formed integrally with a hinge-shaped connecting portion provided between both members.

[0036]

According to the connection structure of a branch connector according to the present invention, the insulating connector main body holding both twisted pair wires is provided with a pair of pressure contact terminals having pressure contact blades, so that the trunk twisted pair wire and the twisted pair wire for trunk line are provided. It can be connected without the need for a work process of exposing the core wire by peeling off the covering material of the twisted pair wire for branch line, and the twisted pair wire pressure contact portion for trunk line and the twisted pair wire pressure contact portion for branch line that are opposite in pressure contact direction are connected. Since the two twisted-pair wires are provided so as to be connected to each other, they do not interfere with each other when the one twisted-pair wire is pressed and connected, thereby improving workability.

At the time of press-connecting, a cover body to which a twisted pair wire for a trunk line is attached and a cover body to which a twisted pair wire for a branch line is fixed are used for both twisted pair wire press-contact portions. Since the connection can be easily performed by attaching the branch connection, the workability of the branch connection is further improved. Also,
Since it is composed of the connector body and the lid having such a simple shape and provided with the press contact terminal, the number of parts is small and the manufacturing cost can be reduced.

Further, by adopting such a configuration, it can be used for other than branch connection between twisted pair wires. For example, one of the crimped connection parts is connected to the trunk twisted pair wire or the branch twisted pair wire, and the other crimped connection part is provided with a resistor for setting the terminating resistance of the twisted pair wire or a capacitor for noise suppression. These elements can be easily added to the twisted pair circuit by connecting the elements mounted for pressure contact by pressure contact.

In this case, the connecting portion for connecting the main wire twisted pair wire pressure contact portion and the branch wire twisted pair wire pressure contact portion whose pressure contact directions are opposed to each other is perpendicular to the direction of pressure contact with the main wire twisted pair wire pressure contact portion and the branch wire. If it is formed so as to be connected to the twisted pair wire press-connecting portion, the press-connecting work can be performed in a small working space for press-connecting, so that workability in a narrow wiring place is improved.

Further, if the connector main body is constituted by a pair of divided bodies, it is possible to assemble the pressure contact terminal by mounting the pressure contact terminal inside the connector main body without integrally forming the connector main body with the pressure contact terminal provided inside. Since it becomes possible, replacement of the press contact blade after assembling can be performed.

If the connector body is provided with a fixing portion for fixing the twisted pair wire for the trunk line and the twisted pair wire for the branch line, the twisted pair wire can be temporarily fixed at the time of the press-connecting operation. The workability of the crimp connection is further improved. At this time, if a clamp portion is provided at the distal end of the fixing portion so as to be engaged with a fixing hole formed in another member where the press-connecting branch connector is arranged, the branch connector is provided. It can be fixed to other members. Further, if a member for preventing detachment is attached to the end of the end of the twisted pair wire for branch line, detachment from the press contact portion is prevented even if the member is pulled.

Further, a resistance element such as a chip resistor used as impedance matching when a twisted pair wire having a different circuit impedance is connected between a pair of press contact terminals provided in the connector body, and noise reduction of a transmission line of the twisted pair wire. For example, if a configuration is adopted in which an electrical element such as a noise filter element such as a chip capacitor is interposed and connected, a member and a mounting space for separately adding such an electrical element to the circuit of the twisted pair wire Can be added without the need.
