Description

  The present invention relates to a protector covering an outer periphery of an electronic device or the like.

  Conventionally, various electronic devices have been proposed (see Patent Document 1). Some electronic devices have a structure in which the outer periphery of the electronic device is covered with a shield shell (protector) in order to protect and shield the device. 8 to 12 show a conventional example of such a structure.

  8 to 12, the connector device 50 includes a first connector 51, a second connector 52 connected to the first connector 51 via an electric wire W, and a shield shell 60 that is a shield member covering the outer periphery thereof. And.

  The shield shell 60 includes a first lower shield shell member 61 and a first upper shield shell member 62 that cover the upper side of the first connector 51 and the electric wire W, and a second lower shield that covers the lower side of the second connector 52 and the electric wire W. A shell 63 member and a second upper shield shell member 64 are provided. These shield shell members 61 to 64 are each formed by press molding from a metal material such as an iron plate (SPCE).

  As shown in detail in FIG. 13, the second upper shield shell member 64 is formed with a notch 64 a. This notch 64a is formed because of the necessity for press working.

JP2013-12457A

  However, in the conventional example, each shield shell member 61 to 64 constituting the shield shell 60 is formed of a metal material such as an iron plate, so that the shield shell 60 is weighted. Thereby, the weight of the connector apparatus 50 which is an electronic device becomes heavy. Moreover, since each shield shell member 61-64 is formed by press work, since it receives restrictions on press work (drawing depth, drawing direction), the degree of freedom in shape is low. Furthermore, when forming the notch part 64a like the 2nd upper shield shell member 64, the notch part 64a invites reduction of a shield performance.

  Accordingly, the present invention has been made to solve the above-described problems, and an object of the present invention is to provide a protector capable of achieving weight reduction, improvement in shape freedom, and improvement in shielding performance.

The present invention is a protector for covering the outer periphery of an electronic device, a resin main body formed from a synthetic resin material, a conductive film layer formed from a conductive material and provided on the inner surface of the resin main body, A collar having a bolt insertion hole is embedded in the mounting portion of the resin main body, the collar is formed of a conductive material, protrudes from the surface of the resin main body, and is also formed on the inner surface of the collar. A protector in which the conductive coating layer is formed .

The resin main body is preferably formed from a colored synthetic resin material . Before Symbol electronic equipment, including the case of a connector device.

  According to the present invention, since the protector has the resin main body portion formed of the synthetic resin material, the weight can be reduced. Moreover, since the resin main body part of a protector can be produced by the injection molding of a synthetic resin whose shape restrictions are much smaller than that of press processing, the degree of freedom in shape is high. Furthermore, the necessity for forming a notch for the reason for injection molding is far less than that of press working, so that the shielding performance is improved. As described above, it is possible to reduce the weight, improve the degree of freedom in shape, and improve the shielding performance.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  1 to 7 show an embodiment of the present invention. As shown in FIGS. 1 to 3, a connector device 1 that is an electronic device includes a first connector 2, a second connector 10 connected to the first connector 2 via an electric wire W, a first connector 2, and an electric wire. W and a protector 20 that covers the outer periphery of the second connector 10.

  The first connector 2 includes a housing 3 having a connection opening 3a and a plurality of connection terminals 4 arranged in the connection opening 3a. An LA terminal (not shown) fixed to an electric wire (not shown) on one side is connected to each connection terminal 4 of the first connector 2 by screwing or the like.

  The second connector 10 includes a housing 11 having a plurality of connection openings 11a and a plurality of connection terminals 12 disposed in the connection openings 11a. An LA terminal (not shown) fixed to the other side electric wire (not shown) is connected to each connection terminal 12 of the second connector 10 by screwing or the like.

  The protector 20 includes a first lower protector member 21 and a first upper protector member 22 that cover the upper side of the first connector 2 and the electric wire W, a second lower protector member 23 that covers the lower side of the second connector 10 and the electric wire W, and And a second upper protector member 24.

  The first lower protector member 21 and the first upper protector member 22 cover the outer periphery excluding the connection opening 3 a of the first connector 2. The second lower protector member 23 and the second upper protector member 24 substantially cover the outer periphery excluding the connector fitting portion of the second connector 10.

  Next, the structure of each protector member 21-24 is demonstrated to the 2nd lower protector member 23 as an example. As shown in FIGS. 6A and 6B, the second lower protector member 23 includes a resin main body portion 25 formed of a synthetic resin material, and a conductive coating layer provided on the inner surface of the resin main body portion 25. 26 double-layer structure.

  The resin main body 25 is formed from a colored synthetic resin. The color of coloring is set to a color that can be distinguished from other connector devices 1. The conductive coating layer 26 is formed of a conductive metal material. The conductive coating layer 26 is formed by resin plating, vapor deposition, application of conductive paint, sputtering, or the like. The 2nd lower protector member 23 has the base protector part 23a and the inclination protector part 23b which inclines in the diagonal direction with respect to this base protector part 23a. Reinforcing ribs 23c are provided at the boundary between the base protector portion 23a and the inclined protector portion 23b. At a plurality of locations of the base protector portion 23a, mounting portions 23d are projected. As shown in detail in FIGS. 7A and 7B, a collar (spacer) 27 is embedded in each mounting portion 24d. The collar 27 is a ring shape made of a conductive metal, and the center hole is a bolt insertion hole 27a. A conductive coating layer 26 is also formed on the inner surface of the collar 27. The resin main body 25 side of the collar 27 protrudes from the surface of the resin main body 25 by d.

  In the second lower protector member 23, the mounting portion 23d is disposed on the mounted portion (not shown), and a bolt (not shown) is passed through the bolt insertion hole 27a from the resin main body 25 side to be mounted (not shown). It is fixed by screwing in. The conductive coating layer 26 is grounded using a collar 27, a bolt (not shown), a mounted portion (not shown), etc. as a ground path.

  As described above, each protector member 21 to 24 constituting the protector 20 has the resin main body portion 25 formed of a synthetic resin material and the conductive coating layer 26 provided on the inner surface of the resin main body portion 25. . Accordingly, the protector 20 protects the first connector 2 and the like by the strength of the resin main body 25 and shields electromagnetic waves from inside and outside by the conductive coating layer 26, and thus has a shielding performance.

  Since the protector 20 is formed by the resin main body 25 mainly formed of a synthetic resin material, the weight is reduced. Thereby, weight reduction of the connector apparatus 1 can be achieved. Further, the resin main body 25 can be manufactured by injection molding of a synthetic resin, which has much less shape restrictions than press processing, and thus has a high degree of freedom in shape. Furthermore, since the necessity of forming a notch for the reason for injection molding is far less than that of press working, the first connector 2 and the like can be covered with no gap as much as possible, and the shielding performance is improved. As described above, it is possible to reduce the weight of the protector 20, improve the degree of freedom in shape, and improve the shielding performance.

  In addition, since the resin main body portion 25 of the protector 20 is resin-molded, the edge processing that is necessary in the conventional example is unnecessary.

  The resin main body portion 25 is formed from a colored synthetic resin material, and the conductive coating layer 26 is provided on the inner surface of the resin main body portion 25. Therefore, it is possible to achieve both the identification function of the protector 20 and the shielding performance. When it is not necessary to provide an identification function, the conductive coating layer 26 may be provided on the outer surface of the resin main body 25, or the conductive coating layer 26 is provided on both the inner and outer surfaces of the resin main body 25. May be.

  A collar 27 having a bolt insertion hole 27 a is embedded in the mounting portion 23 d of each protector 20. Accordingly, it is possible to prevent the resin main body portion 25 from being cracked by a bolt fastening force or the like.

  The collar 27 is formed of a conductive material and protrudes from the surface on the resin main body 25 side. Therefore, it is possible to prevent a fastening force of a bolt (not shown) from acting on the resin main body portion 25. Further, since the fastened bolt (not shown) and the collar 27 are in reliable electrical contact, the bolt (not shown) and the collar 27 can be used as a ground path as in this embodiment.

  In this embodiment, the electronic device is the connector device 1, but it goes without saying that the present invention can be applied to an electronic device other than the connector device 1.
