Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector having a coaxial terminal.

[0002]

2. Description of the Related Art Conventionally, a multi-pole type connector having a normal terminal and a coaxial terminal has a coaxial terminal attached to a coaxial wire and a normal terminal attached to a normal wire, and these terminals are assembled to a connector housing. . When a large number of terminals are usually provided, they may be divided into a plurality of sets, each of which is accommodated in a block housing, and then each of the block housings is fitted to a connector housing to be assembled. I have. However, since the coaxial terminal may have a relatively large shielding metal shell in some cases, the coaxial terminal is directly inserted into the connector housing without using a block housing.

[0003]

However, as described above, when a large number of terminals including a coaxial terminal are mounted on the connector housing, the coaxial terminal is directly mounted on the connector housing without using a block housing. The workability is poor because it is necessary to assemble each terminal to the connector housing separately. In addition, the work of attaching wires to each terminal,
The work of assembling each terminal to the connector housing
Since each process is performed in a separate process, it is necessary to temporarily store each terminal to which the electric wire is attached. However, since the coaxial terminal is exposed without being housed in the block housing, it is stored and transported. In such a case, there is a possibility that deformation due to external force may occur due to being pinched. In particular, when the coaxial terminal has a large-sized shielding metal shell, the coaxial terminal is more susceptible to an external force, and thus is likely to be deformed. If the deformation is large, the connection between the coaxial terminal and the terminal of the mating connector may be difficult to be performed, or a connection failure may be caused, thereby lowering connection reliability.

[0004] It is an object of the present invention to improve the connection reliability by eliminating the deformation of the coaxial terminal due to the external force, and to assemble the coaxial terminal and the normal terminal into the connector housing when the multi-pole type is used. It is an object of the present invention to provide a connector having a coaxial terminal capable of increasing the power.

[0005]

In order to achieve the above object, the connector of the present invention accommodates a coaxial terminal in a coaxial block housing and fits the coaxial block housing to the connector housing. .

According to the above, since the coaxial terminal is accommodated in the coaxial block housing for protection, it is possible to prevent the coaxial terminal from being deformed by an external force when the coaxial terminal is stored or transported. You. Therefore, connection reliability is improved.

When the present invention is applied to a multi-pole type connector having a coaxial terminal and a normal terminal, the coaxial block housing accommodating the coaxial terminal is fitted into the connector housing together with the normal block housing accommodating the normal terminal. Is preferred. In this way, both terminals are simultaneously fitted into the connector housing via the coaxial block housing and the normal block housing to prevent the deformation of the coaxial terminal and the normal terminal due to external force, thereby improving the connection reliability. It becomes possible to assemble. Therefore, workability in the case of a multi-pole type connector is improved.

Further, in the connector of the present invention, if a terminal lance for holding the coaxial terminal housed therein is formed in the coaxial block housing assembled to the connector housing, even if a tensile force is applied to the coaxial terminal, The coaxial terminal is held in the coaxial block housing by the terminal lance and does not come out of the housing.

Further, in this connector, when the coaxial block housing is fitted to the connector housing, the surface on which the terminal lance is formed and the surface on the opposite side thereof come into contact with each other, thereby restricting the displacement of the terminal lance. Preferably, a surface is formed. With this configuration, when the coaxial block housing is fitted to the connector housing,
Since the displacement of the terminal lance can be regulated by the regulating surface provided in the connector housing, the function of holding the coaxial terminal by this terminal lance is reliably exerted, and this coaxial terminal is more reliably pulled out of the coaxial block housing by the tensile force. Is prevented.

[0010] Preferably, the connector housing and the coaxial block housing are provided with retaining means for retaining both of them. According to this configuration, when the coaxial block housing is fitted to the connector housing, the coaxial block housing is securely held in the fitted state by the retaining means without falling out.
