Description

  The present invention relates to a cable connector for connecting, for example, a very thin coaxial cable.

  A coaxial cable is generally configured by arranging a core wire as a conductive path and a shield wire (also referred to as a shield layer) in a single electric wire. Specifically, a core wire is arranged on the central axis, and an insulator, a net-like shield wire, and a covering insulator that are concentric with the core wire are arranged in the radial direction from the axis. In a connector used to connect such a coaxial cable to an electronic device, the core wire is connected to a contact (see, for example, Patent Document 1), and the shield wire is connected to a ground member.

The connector used for such a coaxial cable has a holding member made of an insulating material for holding the contact, a metal shell member attached so as to cover the upper and lower bottoms of the holding member, and a mating connector. The lock portion that holds the lock and the ground member described above are mainly configured. For example, the ground member is formed in a metal plate shape connected to the shielded wires of coaxial cables arranged on the same plane, and is connected to the shell member.
Japanese Patent Laid-Open No. 2005-5102

  However, in such a conventional connector, since the lock portion and the shell member are separately formed, it is necessary to assemble the lock portion and the shell member separately, which increases the number of assembly steps and increases the cost. It was a cause. Further, when the lock portion is attached to the connector as a separate body, there is a problem that a space for providing the lock portion is increased and the entire connector is also increased. Furthermore, there is a case where the lock portion is not electrically connected to the shell member, and there is a possibility that the non-grounded lock portion becomes an antenna against signal noise or the like.

  The present invention has been made in view of such a problem, and provides a cable connector that reduces the manufacturing cost by reducing the number of parts and secures a transmission path for a ground signal and improves electrical performance. Objective.

  In order to solve the above-described problems, the cable connector according to the present invention includes a first insulating coating (for example, the inner peripheral side insulating coating 4 in the embodiment), a shield wire, and a second insulating coating (for example, in the embodiment) around the core wire. A cable connector (for example, a plug connector P in the embodiment) that is attached to an end of a coaxial cable that is formed by being surrounded by the outer peripheral insulating coating 6) and that is fitted and connected to a mating connector (for example, the receptacle connector R in the embodiment). A holding member made of an insulating material having a main body (e.g., the base portion 14 in the embodiment) and a guide protrusion that extends forward from the front end of the main body and guides fitting and detachment with the mating connector; Covers the contact held by the holding member and the lower and upper bottom surfaces facing each other in the main body of the holding member. The first and second shell members made of metal are provided, the core wire of the coaxial cable is electrically connected to the contacts, and the shield wire is electrically connected to the first and second shell members. The plate part (for example, the 1st ground terminal 31 in an embodiment) where it was constituted so that the 1st shell member was connected so that the lower bottom face of the guide projection part might be covered from the tip part of the 1st shell member And a side wall portion that is integrally connected from the plate portion and extends upward and embedded in the guide projection portion, and is integrally connected from the upper end of the side wall portion and protrudes from the upper bottom surface of the guide projection portion to lock the mating connector. And a lock portion for holding.

  In the cable connector configured as described above, the mating connector includes a mating contact that contacts the contact when the cable connector is mated and connected to the mating connector, and a mating mating portion that mates with the guide protrusion. (For example, the receptacle-side space 52 in the embodiment) and a mating holding member made of an insulating material that holds the mating contact, and a metal shield member provided so as to cover the mating holding member When the cable connector is fitted and connected to the mating connector, the first shell member is preferably configured to first contact the shield member via the lock portion.

  Moreover, it is preferable that a plate part is comprised as a connection terminal for a ground connection connected with a shield member, when a cable connector is fittingly connected with the other party connector.

  Furthermore, it is preferable that a locked portion that engages with the lock portion (for example, the lock engagement hole 65 in the embodiment) is formed integrally with the shield member.

  In addition, a plurality of coaxial cables are arranged on the same plane to form a cable assembly, and the cable assembly includes metal ground bars that are electrically connected to the shield wires of the plurality of coaxial cables, respectively. In addition, it is preferable that a contact portion (for example, the contact piece 45 in the embodiment) that contacts the ground bar in an elastically deformed state is formed on the second shell member.

  According to the cable connector according to the present invention, by integrally forming the lock portion and the shell member (second shell member), the lock portion can be grounded via the first and second shell members. The generation of noise can be prevented and the electrical performance can be improved. Further, by integrally forming the lock portion and the shell member (second shell member), the number of parts can be reduced and the number of assembly steps can be reduced, so that the manufacturing cost can be reduced.

  In addition, when the mating contact with the mating contact is configured, the cable connector lock portion is configured to first contact the shield member of the mating connector, so that the metal portion of the cable connector is first mated with the mating connector. Therefore, it is possible to release static electricity or the like to the ground side when fitting and connecting to the mating connector.

  Furthermore, when the plate part is configured as a connection terminal for ground connection that connects to the shield member of the mating connector, when the cable connector is fitted and connected to the mating connector, the plate part becomes the shield member together with the lock part. By contacting, the ground signal transmission path can be increased when the mating connector is fitted and connected, and the electrical performance is further improved.

  Further, since the locked portion that engages with the lock portion is formed integrally with the shield member, static electricity or the like can be released to the ground side when the lock portion is engaged with the locked portion.

  Further, since the second shell member is formed with a contact portion that contacts the ground bar in an elastically deformed state, the ground bar can be connected to the shield wire and the first shell member with a simple configuration without using solder or the like. Can be electrically connected to the second shell member, and the number of assembling steps can be further reduced.
