Description

  The present invention relates to a plug unit including a plurality of predetermined standard plug connectors and a receptacle unit including a plurality of predetermined standard receptacle connectors.

  In portable terminal devices such as tablet PCs, there are an increasing number of cases where peripheral devices such as a keyboard and a mouse are docked. In such a case, in order to realize high-speed transmission, it is required to mount a docking connector having more contacts on the mobile terminal device and peripheral devices. For example, Patent Document 1 describes a docking connector that has a pair of connectors in which a large number of contacts are arranged, and docks one connector to the other connector.

A predetermined space is formed so that the plug connector 76b can move with respect to the front cover 79 (the rear cover 81 fixed to the front cover 79).

  A control portion 89a is provided between the outer wall portion of the plug connector 76a and the front cover 79 (the wall portion 88a formed on the −Y direction side of the opening portion 86a). FIG. 13 is a diagram illustrating a configuration of the control unit 89a. The control unit 89a is made of a conductive member, for example, metal, and four Z-side elastic portions 90a are formed on the + Z direction side of the control unit 89a as shown in FIG. In addition, four Z-side elastic portions 91a are formed on the −Z direction side of the control portion 89a. The control portion 89a is incorporated in the opening 86a, and the Z-side elastic portion 90a pushes the outer wall portion on the + Z direction side of the plug connector 76a in the −Z direction by elastic force. The outer wall portion on the + Z direction side of the plug connector 76a receives the elastic force of the Z-side elastic portion 90a. The Z-side elastic portion 91a pushes the outer wall portion on the −Z direction side of the plug connector 76a in the + Z direction by an elastic force. The outer wall portion on the −Z direction side of the plug connector 76a receives the elastic force of the Z-side elastic portion 91a.

  The controller 89a controls the position of the plug connector 76a in the Z direction with respect to the opening 86a using the elastic force of the Z-side elastic portions 90a and 91a. For example, when a force in the −Z direction is applied to the plug connector 76a, the Z side elastic portion 90a extends in the −Z direction, and the Z side elastic portion 91a contracts in the −Z direction. Accordingly, the plug connector 76a moves in the −Z direction within a predetermined space formed between the outer wall portion of the plug connector 76a and the wall portion 88a. When a force in the + Z direction is applied to the plug connector 76a, the Z side elastic portion 90a contracts in the + Z direction, and the Z side elastic portion 91a extends in the + Z direction.

The X-side elastic portion 93a pushes the outer wall portion on the −X direction side of the plug connector 76a in the + X direction by an elastic force. The outer wall portion on the −X direction side of the plug connector 76a receives the elastic force of the X-side elastic portion 93a.

  The controller 89a controls the position of the plug connector 76a in the X direction with respect to the opening 86a using the elastic force of the X-side elastic portions 92a and 93a. For example, when a force in the −X direction is applied to the plug connector 76a, the X side elastic portion 92a extends in the −X direction, and the X side elastic portion 93a contracts in the −X direction. Accordingly, the plug connector 76a moves in the −X direction within a predetermined space formed between the outer wall portion of the plug connector 76a and the wall portion 88a. When a force in the + X direction is applied to the plug connector 76a, the X-side elastic portion 92a contracts in the + X direction, and the X-side elastic portion 93a extends in the + X direction. Accordingly, the plug connector 76a moves in the + X direction within a predetermined space formed between the outer wall portion of the plug connector 76a and the wall portion 88a.

  Further, as shown in FIG. 13, four Y-side elastic portions 94a are formed on the + Y direction side of the control portion 89a. The control part 89a controls the attitude | position of the plug connector 76a with respect to the opening part 86a using the convex part 67a (refer FIG. 11) formed in the Y side elastic part 94a and the back cover 81.

  Next, the configuration of the plug connector 76b will be described. As shown in FIG. 11, the plug connector 76b is mounted on a circuit board 82b. The plug connector 76b includes a plurality of contacts and a plug shell 65b (see FIG. 9) (not shown). These configurations are the same as the configurations of the plurality of contacts 85a and 59a and the plug shell 65a, respectively, with the center line in the Y-axis direction of the plug docking connector 75 being axisymmetric. One end of a plurality of cables 83b is fixed to the + Z direction side of the circuit board 82b by soldering or the like. Each of the plurality of cables 83b is electrically connected to each of the plurality of contacts 85b disposed on the + Z direction side of the plug connector 76b.

  Here, the circuit boards 82a and 82b on which the plug connectors 76a and 76b are mounted hold one ends of the plurality of cables 83a and 83b because the ends of the plurality of cables 83a and 83b are fixed to the circuit boards 82a and 82b. Functions as a first holding unit. Details of the first holding unit will be described later.

  Next, the configuration of the rear cover 81 will be described. As shown in FIG. 9, the rear cover 81 is attached and fixed to the front cover 79, and supports the plug connectors 76a and 76b from the −Y direction side. On the −X direction side of the rear cover 81, as shown in FIG. 11, an opening 101 a for leading the cable 96 a is formed from the space formed between the front cover 79 and the rear cover 81 to the outside. ing.
