In table taps, an arc may be generated when the blade of the insertion plug is inserted into or removed from the blade holder spring, and heat may be generated at the contact between the blade and the blade holder spring, so the blade The inner peripheral surface of the case in which the receiving spring is housed is required to have heat resistance and tracking resistance. Further, since the table tap is used in a movable manner, it may be dropped or collided with other objects, so the outer circumferential surface of the case is required to have impact resistance. By the way, since it is difficult to satisfy heat resistance, tracking resistance, and impact resistance with the same material, conventional materials with heat resistance and tracking resistance (
- The inner case is made of a thermosetting synthetic resin), a conductor with a blade receiving spring is disposed inside the inner case, and the outer periphery of the inner case is made of impact-resistant material ( Generally, the outer shell is made of thermoplastic synthetic resin). An example of this table tap is shown in FIGS. 3 and 4. This table tap has an inner case 10 made of a material with excellent heat resistance and tracking resistance, and an inner case 10 made of a relatively soft material with excellent impact resistance. It has an outer shell 20 that encloses the case 10, and a portion of the inner case 10 where the blade insertion opening 11 is provided is exposed at key points of the outer shell 20. An external electric wire 30 is drawn out from the outer shell 20, and a plug 31 is connected to the other end of the external electric wire 30. As shown in FIG. 4, the inner case 10 includes a pair of conductors 3.
2. Assemble the body 12 to which 32 is attached and the cover 13 to be fitted onto the body 12 using a connecting tool 1 such as screws or rivets.
It is formed by joining at 4. Inner case 10
Projections 15 are formed at two locations on the top surface and one location on the front surface of the outer peripheral surface of the projector.
A pair of plug blade insertion openings 11 are opened at each of the openings 5. The double-groove electric body 32.32 disposed inside the inner case 10 is formed in a shape having a blade receiving spring 33 at a portion corresponding to each blade insertion opening 11, and has an external electric wire attached to one end by crimping. A wire connecting portion 34 to which the wire 30 is connected is formed. In addition, claw pieces 35, 35 are formed by cutting and raising in the middle part of each conductor 32 in the longitudinal direction, and the double groove electric body 3232 has these claw pieces 35, 35 formed in the locking hole 17 provided in the body 12. Reference numeral 19 in FIG. 0, which is fixed to the body 12 by press-fitting into the body 17, is a partition wall that isolates both groove electric bodies 32 and 32 from each other within the body 12. Then, the body to which the conductor 32 is fixed as described above]2
When the cover 13 is placed on the body 12 and the cover 13 are connected using the connector 14, the wire connection portion 34 formed at one end of the conductor 32 protrudes from one end of the inner case 1O, and is connected to the outside. The electric wire 30 is connected to the electric wire connection part 3 in this state.
4 is connected by caulking. Further, the outer shell 20 is formed by secondary molding on the outer periphery of the inner case 10 after connecting the external electric wire 30 as described above, and wraps substantially the entire periphery except for the surface of the protrusion 15. The wire connection portion 34 and the split portion of the external wire 30 are also covered with the outer shell 20.

Here, the mold for forming the outer shell 20 that covers the inner case 1O by secondary molding requires a large capital investment compared to a normal mold, and the external design has to be changed. It is also difficult from a cost standpoint. The present invention has been made in view of the above-mentioned problems, and its purpose is to provide an inner case and an outer shell that covers the inner case, which is easy to manufacture and which can easily accommodate design changes. It is possible to provide table taps.

Therefore, the present invention provides a table tap that includes a pair of conductors having a blade receiving spring, an inner case in which these conductors are housed, and an outer shell that covers substantially the entire outer surface of the inner case. The shell is divided into a plurality of parts and integrally includes a locking part that is hooked and locked to the inner case, and is attached to the outer surface of the inner case by this locking part. There is. [Function] According to the present invention, since the outer shell can be formed separately from the inner case, in other words, when forming the outer shell as a molded product, it is not a secondary molded product for the inner case, but a normal molding. Since it can be formed as a product, it does not require a mold for secondary molding. [Example] The present invention will be described below based on an illustrated example. In FIG. 1, the inner case 10 and the conductor 32 are constructed in the same manner as in the conventional example, but here they are made of thermoplastic synthetic resin. The outer shell 20 is made up of a body 21 and a cover 22 like the inner case 10, and is hooked and locked in locking recesses 18 formed on both sides of the body 12 and cover 13 in the inner case 10. The hook 25 is integrally provided with a plurality of hooks 25. In the figure, 23 is an opening for exposing the protrusion 15 of the inner case 10 to the outside, and 24 is an opening for sandwiching a cord bushing 39 placed over the end of the power cord 30. Then, a body 21 and a cover 22 which are the outer shell 20
is formed separately from the inner case 10, that is, not as a secondary molded product, but as a normal molded product, and the conductor 3
2. The inner case 10 is assembled with the power cord 30 stored inside and the power cord 30 is connected to the conductor 32, and the hook 25 is hooked into the locking recess 18 and locked By doing so, it is attached to the outer surface of the inner case 10. FIG. 2 shows an example in which a locking recess 18 into which a hook 25 of a cover 22 is locked is provided in the projecting base portion 15.
