[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bolted connector suitably used for a wire harness for automobiles and the like, and more particularly to a bolted connector for connecting a connector having a tab-shaped male terminal guide plate. It was done.

[0002]

2. Description of the Related Art Recently, multi-pole connectors having more than 20 poles have been provided, and when these multi-pole large connectors are fitted together, a very strong coupling force is required, and connection by manual work is not possible. It is possible. Therefore, as shown in FIG. 3, the male connector 1 is provided with a bolt receiving portion 1a, while the female connector 2 is provided with a bolt hole 2a, and the bolt 3 is tightened through the bolt hole 2a to the bolt receiving portion 1a using an impact wrench. A bolted connector is provided that ensures a secure fit.

[0003] Further, in a connector fitted with each other,
When a tab-shaped male terminal is used for one of the male connectors, the male terminal is protected from being deformed by an external force acting on the male terminal, and the male terminal is guided at the time of fitting with the female connector. As shown, the male terminal protection plate 5 is mounted inside the male connector 4, and the male terminals are exposed through guide holes 5a formed in the male terminal protection plate 5.

[0004]

When the male terminal protection plate 5 shown in FIG. 4 is applied to the bolted connector shown in FIG. 3, the male terminal protection plate is in a stable state because the opening area of the fitting hole is large. The male terminal protection plate is attached to the bolted connector because it is difficult to attach the bolt terminal and the bolt receiving portion 1a protrudes from the fitting hole, so that the shape of the male terminal protection plate becomes complicated. Not. For this reason, in this type of bolted connector, a rib is provided to prevent deformation of the male terminal, but high density cannot be achieved due to the installation space of the rib,
This hinders multipolarization.

Further, when attaching the separate male terminal protection plate, the male terminal protection plate must be made thin, so that a large-sized connector for a multipolar connector may be warped or deformed at the time of forming the plate. There is a disadvantage that the male terminal is easily exposed when the plate is pressed, and the protective function of the male terminal cannot be exhibited.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problem, and in a bolt-tightened connector having a large fitting opening and a tab-shaped male terminal mounted thereon, a male terminal protection plate portion is provided integrally with the connector housing. By eliminating the conventional ribs for preventing stiffness, it is possible to increase the density of the connector, and improve the strength of the male terminal protection plate itself so that the male terminals are not easily exposed,
The purpose is to ensure protection of the male terminal.

[0007]

That is, in the present invention, a male terminal protection plate portion having a male terminal guide hole and a bolt hole is integrally formed at an intermediate position in an outer housing of a male connector. A male terminal is mounted in the housing from one end side, and an inner housing provided with a bolt receiving portion is slidably inserted from the one end side, while a female connector is inserted from the other end side of the outer housing and a male connector is inserted from the female connector side. A bolt-tightened connector having a configuration in which the inner housing is moved and tightened by tightening a bolt to the bolt receiving portion through the bolt hole of the terminal protection plate portion, and the male terminal is connected to the female terminal through the male terminal guide hole. Is provided.

[0008]

As described above, since the male terminal protection plate is formed integrally with the outer housing, the male terminal protects the male terminal and guides the male terminal when the connector is fitted even in a bolt-tight connector having a large fitting port. A protection plate can be installed. In addition, since the male terminal is guided by the guide hole provided in the male terminal protection plate when the connector is fitted, the alignment of the male terminal can be corrected, and the male terminal can always be fitted at the correct position.

As is apparent from the above description, in the bolted connector according to the present invention, the male connector is divided into an outer housing and an inner housing, and a male terminal guide hole and a bolt hole are formed in the outer housing. While the terminal protection plate portion is integrally formed, the male terminal is mounted on the inner housing from one end side in the outer housing, so that the male terminal protection plate portion can be installed in a bolted connector having a large fitting opening. I can do it. The male terminal protection plate portion is integrally formed with the outer housing and has an entire periphery continuous with the inner wall of the outer housing, so that the male terminal protection plate portion has a strength and is not easily deformed by an external force. In addition, since the male terminal protruding from the inner housing is not exposed from the male terminal protection plate portion and is housed in the outer housing before fitting with the female connector, it is possible to prevent deformation of the male terminal due to external force. I can do it.

Since the male terminal protection plate portion is provided as described above, the conventionally provided rib for preventing stiffening is not required, so that the terminals can be mounted at high density inside the connector.

Furthermore, since the male connector is divided into an outer housing and an inner housing, only the inner housing having the male terminal mounted thereon can be mounted on the junction block together with the female connector and mounted, and generalization of parts can be achieved. And so on.
