Embodiment 1
The shield connector 1 according to the present embodiment shown in FIGS. 1 and 2 is applied to, for example, a wire harness WH1 or the like used in an automobile or the like. The wire harness WH1 is, for example, a bundle of a plurality of wiring materials W used for power supply and signal communication for connection between devices mounted on a vehicle, and a plurality of wiring by connectors etc. The material W is connected to each device. The wire harness WH1 is electrically connected to the end of the wiring material W having electrical conductivity, the braided conductor B through which the wiring material W is inserted, and the end of the braided conductor B. And a shield connector 1 to be mounted. The wiring material W is formed of, for example, a metal rod, an electric wire, a wire bundle or the like. The metal rod is the one in which the outside of the conductive rod member is covered by the insulating covering portion. The electric wire is obtained by covering the outside of a conductor portion (core wire) made of a plurality of conductive metal wires with an insulating covering portion. The wire bundle is a bundle of the wires. The braided conductor B is a tubular conductor in which a plurality of braided wires are braided in a cross shape. The braided wire of the braided conductor B is formed of, for example, a conductive metal material such as copper or aluminum. The braided material B is inserted into the inside of the braided conductor B to shield an electromagnetic wave (electromagnetic force). The braided conductor B shields unnecessary electromagnetic waves (unnecessary electromagnetic waves) causing noise and the like to suppress noise. That is, the braided conductor B prevents the penetration of the electromagnetic wave into the wiring material W which is the noise reduction target portion and the leakage of the electromagnetic wave from the wiring material W which is the noise reduction target portion. As a result, the braided conductor B shields the electrical noise generated by the wiring material W, which is the noise reduction target area, and the electrical noise that affects the wiring material W, which is the noise reduction area. The shield connector 1 constitutes a shield circuit that shields noise by being electrically connected to the braided conductor B. The wire harness WH1 may further include a grommet, a protector, a fixture, an electrical connection box, and the like.

  The shield connector 1 of this embodiment typically uses a device such as an inverter as a connection partner D, and constitutes a connection device for a wiring material pair device that connects the wiring material W and the connection partner D. is there. The shield connector 1 is fastened to a housing of a device such as an inverter which is the connection partner D, and forms an electrical connection portion with the connection partner D. The shield connector 1 of the present embodiment has such a configuration, and by providing the press-fit structure portion 50, the improvement of the assemblability of each part is achieved. Hereinafter, each configuration of the shield connector 1 will be described in detail with reference to the respective drawings.

  Specifically, as shown in FIGS. 1 and 2, the shield connector 1 includes a housing 10, an inner cover 20, a packing 30, a shield shell 40, a press-fit structure 50, and an outer cover 60.

  The housing 10 accommodates and holds the terminal T provided at the end of the wiring material W. The terminal T is a metal fitting made of a conductive metal material. The terminal T is electrically connected to the end of the wiring material W. The terminal T is electrically connected to a counterpart terminal provided on the connection counterpart D to form an electrical connection portion. The terminal T is electrically connected to the other terminal by, for example, being fastened at the tip end with the other terminal by a bolt and bolted. The housing 10 includes a cylindrical portion (housing side cylindrical portion) 11 and a terminal holding portion 12. The housing 10 is integrally formed of a resin material having an insulating property as a whole including the cylindrical portion 11 and the terminal holding portion 12. The cylindrical portion 11 is a portion through which the wiring material W is inserted. The cylindrical portion 11 is formed in a cylindrical shape having a central axis along the axial direction X. Here, the cylindrical portion 11 is formed in a substantially elongated cylindrical shape. The cylindrical portion 11 is formed to extend along the axial direction X. The cylindrical portion 11 is open at one end in the axial direction X. The other end of the cylindrical portion 11 in the axial direction X is connected to the terminal holding portion 12 and is continuous with the terminal holding portion 12. In the cylindrical portion 11, the wiring material W is inserted from one end to the other end along the axial direction X (see also FIGS. 3 and 4). Here, in the cylindrical portion 11, two wiring materials W are inserted into the inside. The terminal holding portion 12 is a portion that holds the terminal T. Here, the terminal holding portion 12 holds the respective terminals T of the two wiring materials W, that is, a total of two terminals T. The terminal T extends in the thickness direction Z while being held by the terminal holding portion 12. The terminal holding portion 12 holds the terminal T in such a positional relationship that the tip of the terminal T is exposed to one side in the thickness direction Z. That is, the housing 10 holds the terminal T along the thickness direction Z in which the wiring material W is derived along the axial direction X and intersects the axial direction X. Further, the terminal holding portion 12 has an opening 12 a. The opening 12 a opens in a substantially rectangular shape on the side opposite to the tip end side of the terminal T along the thickness direction Z. The opening 12 a functions as, for example, an opening for work when fastening the terminal T.

  The inner cover 20 is a waterproof cover member that closes the opening 12 a provided in the housing 10 to be waterproof. The inner cover 20 is formed in a shape corresponding to the shape of the opening 12a. Here, the inner cover 20 is formed in a substantially rectangular plate shape in which the thickness direction Z is the thickness direction and the opening 12a can be closed. The inner cover 20 is formed of an insulating resin material. The inner cover 20 is fitted to the opening 12a and attached to the opening 12a, for example, after completion of the fastening operation of the terminal T through the opening 12a.

  The packing 30 is a sealing member for waterproofing formed in an annular shape. The packing 30 is formed of a resin material having an insulating property and a relatively high elasticity. The packing 30 is attached to the outer surface of the inner cover 20. The packing 30 is provided in the opening 12 a together with the inner cover 20. The packing 30 is interposed between the inner surface of the opening 12 a and the outer surface of the inner cover 20 in a state in which the inner cover 20 is fitted in the opening 12 a and closes the opening 12 a. In this state, the packing 30 contacts the inner surface of the opening 12 a and the outer surface of the inner cover 20. With this configuration, the packing 30 seals the gap between the inner surface of the opening 12 a and the outer surface of the inner cover 20.

  The shield shell 40 is a shield member which covers the outside of the housing 10 in a state in which the wiring material W is drawn out and holds the terminal T, and which shields electromagnetically. The shield shell 40 has a lower shell 41 as a first shell and an upper shell 42 as a second shell. The lower shell 41 and the upper shell 42 are formed of a conductive metal material. The lower shell 41 and the upper shell 42 are provided to face each other across the housing 10 in the thickness direction Z. The lower shell 41 and the upper shell 42 form a housing space portion 43 in the thickness direction Z (see also FIG. 4 and the like). The shield shell 40 accommodates the housing 10 in an accommodation space 43 formed between the lower shell 41 and the upper shell 42. That is, the shield shell 40 sandwiches the housing 10 from both sides by the lower shell 41 and the upper shell 42 and accommodates the housing 10 in the accommodation space portion 43. In other words, the lower shell 41 is located on one side of the housing 10 in the thickness direction Z, and covers a part of the housing 10 from one side in the thickness direction Z. The upper shell 42 is positioned on the other side of the housing 10 in the thickness direction Z, faces the lower shell 41, and covers a part of the housing 10 from the other side in the thickness direction Z. The lower shell 41 and the upper shell 42 sandwich the housing 10 between the lower shell 41 and the upper shell 42 and are fastened together by the connection partner D in a state where the housing 10 is accommodated in the accommodation space portion 43. As a result, in the shield shell 40, the relative positions of the lower shell 41 and the upper shell 42 with respect to the connection partner D are fixed. And the lower shell 41 and the upper shell 42 shield electromagnetic waves (electromagnetic force). The lower shell 41 and the upper shell 42 shield unnecessary electromagnetic waves (unnecessary electromagnetic waves) that cause noise and the like to suppress noise. That is, the lower shell 41 and the upper shell 42 prevent the penetration of the electromagnetic wave to the noise reduction target portion and the leakage of the electromagnetic wave from the noise reduction target portion. Here, the noise countermeasure target portion by the lower shell 41 and the upper shell 42 is typically the wiring material W or the terminal T in the housing 10. Thereby, the lower shell 41 and the upper shell 42 are the wiring material in the housing 10 that is the noise reduction target portion and the wiring material in the housing 10 that is the noise reduction target portion generated by the terminals T and the wiring members W. It shields electrical noise that affects W and terminals T.
