(Embodiment 1)
As shown in FIG. 1, the table tap of this embodiment has a pair of plug blade insertion ports 1 arranged in the longitudinal direction of the housing 2, and a plurality of sets (three sets in the figure) of the blade insertion ports 1 are housings. 2 are juxtaposed in the longitudinal direction. Further, in the width direction of the housing 2, a plurality of sets (two sets in the figure) of the blade insertion ports 1 are arranged in parallel. In short, in this embodiment, a plurality of sets (six sets in the figure) of the blade insertion ports 1 are arranged in the longitudinal direction of the housing 2 so as to form a plurality of rows in the width direction of the housing 2. Hereinafter, a portion provided with a plurality of sets of plug blade insertion ports 1 arranged in a line along the longitudinal direction of the housing 2 is defined as a functional surface 20 in the housing 2. That is, in FIG. 1, since two rows of plug blade insertion ports 1 are provided in the width direction of the housing 2, the housing 2 has two functional surfaces 20 in the width direction.

  By the way, this embodiment differs in the shape of the housing 2 from the conventional structure. Specifically, the housing 2 is formed in a box shape by combining a base 22 including a rectangular bottom surface 21 and a cover 23 including a functional surface 20 and accommodating a conductive member 6 described later. The shape of the base 22 is the same as that of the conventional configuration, but is different from the conventional configuration in that one of the functional surfaces 20 of the cover 23 is inclined so as to approach the bottom surface 21 toward one end in the width direction of the housing 2. ing. That is, the two functional surfaces 20 are not flush with each other, and the cross section perpendicular to the longitudinal direction of the housing 2 has a pentagonal shape as shown in the side view of FIG.

  By inclining at least one of the functional surfaces 20 as described above, the dimension in the width direction of the housing 2 can be reduced as compared with the case where the functional surface 20 is not inclined. As a result, a plurality of sets of plug blade insertion ports 1 are juxtaposed in the longitudinal direction of the housing 2 so that each pair of plug blade insertion ports 1 is aligned in the longitudinal direction of the housing 2. Even if a configuration in which a plurality of sets are arranged in parallel in the width direction of 2 is employed, the dimension in the width direction of the housing 2 can be made relatively small.

  As shown in FIG. 2, the conductive member 6 includes a blade receiving spring 60 and a terminal portion 61 to which the power cord 7 is connected, and is long in the longitudinal direction of the housing 2 and in the width direction of the housing 2. The terminal 61 and the blade receiving spring 60 are electrically connected by the connecting piece 63. As shown in FIG. 3, the connecting pieces 63 are connected so that the blade receiving springs 60 adjacent in the width direction of the housing 2 have the same polarity, and alternately have different polarities in the longitudinal direction of the housing 2. The connection piece 62 is connected to the terminal portion 61. The conductive member 6 is a set of two, and as shown in FIG. 4, the connecting pieces 62 are arranged in parallel. In this configuration, the connecting piece 62 and the connecting piece 63 are extended to increase the blade receiving spring 60, thereby increasing the length of the housing 2 in the longitudinal direction and the width direction without increasing the number of conductive members 6 accommodated in the housing 2. It is possible to add more mouths.

  Each blade receiving spring 60 has a pair of spring pieces opposed to each other, one end portions of both spring pieces are connected continuously and integrally, and the other end portion (hereinafter referred to as an introduction portion) of both spring pieces is between. Restoring force is generated in the direction approaching each other. The plug blade is inserted from the introduction portion toward one end portion of the spring piece in a direction orthogonal to the functional surface 20. In the present embodiment, since the two functional surfaces 20 intersect with each other, the direction of the introduction portion of the blade receiving spring 60 is different for each functional surface 20. Therefore, as shown in FIG. 4, by bending the connecting piece 63 to the same angle as the intersection angle of the functional surface 20, the blade receiving springs 60 adjacent in the width direction of the housing 2 are inclined with respect to each other by the intersection angle of the functional surface 20. The blade receiving springs 60 are each directed toward the introduction portion in a direction perpendicular to the functional surface 20.

  The case where an AC adapter is connected to the table tap of this embodiment will be described below with reference to FIGS. The AC adapter 3 is assumed to be a general one having an adapter main body 32 in which a pair of plug blades 30 project and a connection cord 31 is introduced in a direction orthogonal to the pair of plug blades 30.

  In the present embodiment, a plurality of sets of plug blade insertion ports 1 adjacent to each other in the longitudinal direction of the housing 2 are inserted into the plug blade insertion ports 1 adjacent to the adapter main body 32 when the AC adapters 3 are connected to the respective plug blade insertion ports 1. Arranged at a pitch P 1 that does not interfere with the mouth 1. For example, in the present embodiment, assuming that the AC adapter 3 for charging the mobile phone is connected, a pitch P1 of 41 mm is adopted, so that it is provided at both ends in the longitudinal direction of the housing 2 as shown in FIG. Even if the AC adapter 3 for charging the mobile phone is connected to each pair of plug blade insertion openings 1, a general plug 33 is inserted into the pair of plug blade insertion openings 1 provided at the center in the longitudinal direction of the housing 2. Can be connected. That is, four AC adapters 3 and two plugs can be simultaneously connected to the table tap of the present embodiment.

  In addition, as shown in FIG. 6, when the housing 2 is placed on a suitable table A such as a counter and a table tap is used so that the bottom surface 21 faces down, the AC adapter 3 is inclined with respect to the bottom surface 21. By connecting to the pair of plug blade insertion openings 1 provided on the functional surface 20, the protruding direction of the connection cord 31 can be directed to the table A side, so that the table tap including the AC adapter 3 on the table A The occupied area can be made relatively small. Furthermore, the dimension in the direction perpendicular to the bottom surface 21 of the table tap including the AC adapter 3 is also relatively small.

  The housing 2 includes a heat-resistant portion 24 of a thermosetting synthetic resin molded product having heat resistance and an impact-resistant portion 25 of a thermoplastic synthetic resin molded product having impact resistance. The heat-resistant portion 24 is exposed around each set of plug blade insertion openings 1 on the functional surface 20.

Are arranged at a pitch P2 that does not interfere. For example, in the case shown in FIG. 7, a pitch P2 of 29 mm is adopted.

  On the other hand, as shown in FIG. 8, it is easy to increase the pitch P <b> 3 of a plurality of sets of plug blade insertion ports 1 adjacent to each other in the longitudinal direction of the housing 2. With this table tap, even if it is larger than the AC adapter 3 for charging a mobile phone, it can be connected without interfering with the adjacent plug blade insertion opening 1.

  The power cord 7 is introduced into the housing 2 at one end in the longitudinal direction of the housing 2 as in the conventional configuration, and a bushing 27 is provided at a portion of the housing 2 where the power cord 7 is introduced. ing. At the one end portion where the bushing 27 in the longitudinal direction of the housing 2 is provided, since the terminal portion 61 is provided in the housing 2, each plug blade insertion port 1 is arranged away from one end edge in the longitudinal direction of the housing 2. The

Meanwhile, strip of the present embodiment, as shown in FIGS. 9 and 10, or may be formed by continuous form across the heat unit 24 into a plurality of sets of blade insertion slots 1.

According to this configuration, the uneven shape in the heat-resistant portion 24 can be reduced, and the shock-resistant portion 25 only needs to be formed with one large opening 26 that exposes the heat-resistant portion 24. Both shapes with the part 25 can be simplified. Moreover, since this configuration has taken a relatively large opening 26 of the impact portion 25, the material used for the impact portion 25 may turn less.
