The conduction plate 50 has a substantially rectangular plate shape when viewed from the front. The conduction plate 50 has a groove portion 52 at the upper end. The groove portion 52 is recessed downward in a substantially U shape from a position corresponding to the groove 11 in the upper end portion of the conduction plate 50, and a position slightly above the inner surface of the groove 11 is a bottom portion. Since both corners on the upper side of the groove 52 are arcuately tapered, the wiring A1 can be easily drawn into the inside of the groove 52. The groove widths (lengths in the left-right direction) of the groove portions 52 are separated by a width smaller than the diameter of the wiring A1. However, for example, even if the bundle width of the conductor wires 101A excluding the coating 101B of the wiring A1 is made substantially the same. Good. Further, the groove width of the groove portion 52 is the same width from the top to the bottom, but the width may be gradually narrowed from the top to the bottom, for example.

Further, the recess 17 on the first base portion 5 side and the recess 37 on the second base portion 7 side have the same groove shape. Since the convex portion 16 and the concave portion 37 and the convex portion 36 and the concave portion 17 are in a relationship such as the convex portion and the concave portion of the LEGO (registered trademark) block, they are integrated by engaging with each other. Thereby, the first holding part 2 and the second holding part 3 are held in a state of being connected to each other.

-Structure of the second lid 8-
The second lid portion 8 is connected to the left side portion of the second base portion 7 via a pair of connecting portions 47 and 48 described below, and is provided so as to be openable and closable on the upper surface of the second base portion 7. ing.

The outer upper surface portion 43 is a surface that comes into contact with the outer upper surface portion 32 of the second base portion 7 when the second lid portion 8 is superposed on the second base portion 7. An insertion groove 44 is provided in a portion of the outer upper surface portion 43 corresponding to the central portion 322. The insertion groove 44 is formed in a substantially rectangular shape extending in the left-right direction in plan view along the inner surface of the groove 41. When the second lid portion 8 is overlapped with the second base portion 7, the upper portion of the conduction plate 60 fixed to the plate groove 31A of the second base portion 7 is inserted into the insertion groove 44. Further, a locking wall portion 49 that closes the front end side of the groove 41 is provided between the front end portion of the inner upper surface portion 42 and the front end portion of the outer upper surface portion 43. The upper end portion of the locking wall portion 49 is formed in a semi-circular shape and corresponds to the shape of the groove 31 of the second base portion 7. For example, the locking wall portion 49 can lock the end of the wiring C2 so that the wiring C2 arranged in the groove 41 does not protrude outside the electrotap 1.

A mating surface 401 is provided on the right side surface of the second lid portion 8. The mating surface 401 is a plane parallel to the vertical direction. The mating surface 401 becomes substantially flush with the separating/connecting surface 35 of the second base portion 7 when the second lid portion 8 is superposed on the second base portion 7, and thus is substantially flush with the first holding portion. It faces the mating surface 201 of the first lid part 6 of No. 2. In the portion of the mating surface 401 corresponding to the central portion 322, the above-described insertion groove 44 is formed in a cut shape from the upper end of the mating surface 401 to the substantially middle position. A locking frame portion 45 is provided on the left side surface of the second lid portion 8 so as to project upward. The locking frame portion 45 is formed in a substantially inverted U shape when viewed from the left side. As will be described later, when the second lid portion 8 is superposed on the second base portion 7, the locking frame portion 45 is provided with a conical portion 39 provided on the right side surface of the support wall 38 of the second base portion 7. It contacts the peripheral surface and slides downward. When the locking frame part 45 slides down on the peripheral surface of the conical part 39, the bottom part of the conical part 39 is locked inside the locking frame part 45. As a result, the second lid portion 8 is closed and fixed to the second base portion 7.

The pair of connecting portions 47, 48 is provided between the right end portion of the inner upper surface portion 33 of the second base portion 7 and the left end portion of the inner upper surface portion 42 of the second lid portion 8, and the second base portion 7 is provided. And the second lid portion 8 are connected so as to be bendable in a hinge shape.

The connecting portions 47 and 48 are formed in an elongated substantially rectangular plate shape extending in the left-right direction, and are formed thin enough to be bendable. The above-mentioned locking frame portion 45 is arranged between the connecting portions 47 and 48, and the support wall 38 is arranged so as to face the locking frame portion 45.

The conduction plate 60 is inserted and fixed from above into the support wall 38, the groove 31, and the plate groove 31A provided in the outer upper surface portion 32. The conduction plate 60 can also be made of metal, but any member having conductivity can be used. For example, the plate may be formed of a conductive resin, or the surface may be covered with the conductive resin. The conduction plate 60 has a substantially rectangular plate shape when viewed from the front. The conduction plate 60 has a groove portion 62 at the upper end. The groove portion 62 is recessed in a substantially U-shape downward from a position corresponding to the groove 31 on the upper end portion of the conduction plate 60, and a position slightly above the inner surface of the groove 31 is a bottom portion. Since both corners on the upper side of the groove 62 are arcuately tapered, the wiring C1 can be easily drawn into the inside of the groove 62. The groove widths (lengths in the left-right direction) of the groove portions 62 are separated from each other by a width smaller than the diameter of the wiring C1. Good. Further, the groove width of the groove portion 62 is the same width from the top to the bottom, but the width may be gradually narrowed from the top to the bottom, for example.

An example of a wiring connecting method using the electrotap 1 will be described with reference to FIGS. Here, as shown in FIG. 11A, the most basic connection form for connecting the wiring A1 and the wiring C1 will be described as an example. Note that, as shown in FIGS. 3 and 8, the wiring A1 is a general wiring in which the periphery of the conductive wire 101A is covered with a coating 101B. The wiring C1 is a general one in which the periphery of the conductive wire 102A is covered with a coating 102B.

First, as shown in FIG. 3, the wiring A1 is arranged inside the groove 21 of the first lid portion 6 of the first holding portion 2. At this time, by hooking the end of the wiring A1 on the protrusion 26, the wiring A1 can be prevented from protruding to the outside of the electrotap 1. On the other hand, the wiring C1 is arranged inside the groove 41 of the second lid portion 8 of the second holding portion 3. At this time, by hooking the end portion of the wiring C1 on the locking wall portion 49, it is possible to prevent the wiring C2 from protruding outside the electrotap 1. In this state, the wirings A1 and C1 are arranged substantially parallel to each other.

Next, as shown in FIGS. 5 and 6, the first lid portion 6 is rotated with respect to the first base portion 5 in the direction of arrow P1 in the figure to close it. When the first lid portion 6 is rotated about 90° with respect to the first base portion 5, the locking frame portion 25 of the first lid portion 6 becomes substantially horizontal and its upper end as shown in FIG. The portion contacts the peripheral surface of the conical portion 19 provided on the left side surface of the support wall 18 of the first base portion 5. Further, when the first lid portion 6 is rotated toward the first base portion 5, the upper end portion of the locking frame portion 25 slides downward on the peripheral surface of the conical portion 19. The wiring A1 arranged in the groove 21 is inserted inside the groove portion 52 of the conduction plate 50. Then, the central portion 222 of the first lid portion 6 and the central portion 212 of the first base portion 5 are sandwiched by pliers or the like, and the central portion 222 of the first lid portion 6 is placed on the central portion 212 of the first base portion 5. By pressing the wiring A1 from above, the wiring A1 is pushed downward along the groove 52 (see FIG. 7). Here, since the central portion 222 of the first lid portion 6 and the central portion 212 of the first base portion 5 are the thickest portions among the respective members, the first lid portion 6 and the first base portion 5 are Easy to apply force. At this time, the covering 101B of the wiring A1 is tightened by the inner edge of the groove 52 and is broken, so that the conduction plate 50 comes into contact with the conducting wire 101A of the wiring A1. Then, when the locking frame portion 25 slides down on the peripheral surface of the conical portion 19, the bottom portion of the conical portion 19 is locked inside the locking frame portion 25. As a result, the first lid portion 6 is closed and firmly fixed to the first base portion 5, and the wiring A1 is held.

On the other hand, the second lid part 8 is rotated with respect to the second base part 7 in the arrow P2 direction in FIG. Similar to the first holding portion 2, when the second lid portion 8 is rotated about 90° with respect to the second base portion 7, the locking frame portion 45 of the second lid portion 8 becomes substantially horizontal and The upper end portion contacts the peripheral surface of the conical portion 39 provided on the right side surface of the support wall 38 of the second base portion 7. Further, when the second lid portion 8 is rotated to the second base portion 7 side, the upper end portion of the locking frame portion 45 slides downward on the peripheral surface of the conical portion 39. The wiring C1 arranged in the groove 41 is inserted inside the groove portion 62 of the conduction plate 60. Then, the central portion 322 of the second lid portion 8 and the central portion 312 of the second base portion 7 are sandwiched by pliers or the like, and the central portion 322 of the second lid portion 8 is placed on the central portion 312 of the second base portion 7. By pressing the wiring C1 from above, the wiring C1 is pushed downward along the groove 62. Here, since the central portion 322 of the second lid portion 8 and the central portion 312 of the second base portion 7 are the thickest portions among the respective members, the central portion 322 is different from the second lid portion 8 and the second base portion 7. Easy to apply force. At this time, the coating 102B of the wiring C1 is tightened by the inner edge portion of the groove 62 and is broken, so that the conduction plate 60 contacts the conductive wire 102A of the wiring C1. Then, as shown in FIG. 7, when the locking frame part 45 slides down on the peripheral surface of the conical part 39, the bottom part of the conical part 39 is locked inside the locking frame part 45. As a result, the second lid portion 8 is closed and firmly fixed to the second base portion 7, and the wiring C1 is held.

In this way, as shown in FIGS. 7 and 8, the wiring A1 is held by the first holding portion 2 and the wiring C1 is held by the second holding portion 3. In this state, the conduction plate 50 is in contact with the conductor wire 101A of the wiring A1, and the conduction plate 60 is in contact with the conductor wire 102A of the wiring C1. Further, in the separate connection surfaces 15 and 35, which are the mating surfaces of the first holding portion 2 and the second holding portion 3, the connection surface 51 of the conduction plate 50 and the connection surface 61 of the conduction plate 60 contact each other, One conductive member is configured (see FIGS. 1, 3, and 7). As a result, the wirings A1 and C1 are electrically connected to each other via the conduction plates 50 and 60.

Further, inside the first holding portion 2, the wiring A1 is inserted inside the groove portion 52 of the conduction plate 50 and the cover 101B is broken, so that the conductor wire 101A and the inner edge portion of the groove portion 52 are in contact with each other. Further, since the conduction plate 50 is arranged so as to be orthogonal to the wiring A1, the substantially ring-shaped cut end of the cut coating 101B is formed at the portion where the conductive wire 101A and the inner edge portion of the groove portion 52 are in contact with each other. However, it is in a state of being locked and sandwiched from both sides in the front-rear direction with respect to the inner edge portion of the groove portion 52 of the conduction plate 50. Thereby, even if the wiring A1 is pulled forward, the wiring A1 can be prevented from being pulled out to the outside. This also applies to the wiring C1 inside the second holding unit 3.

A method of disconnecting the wirings A1 and C1 in the electrotap 1 will be described with reference to FIGS. After the wiring A1 and the wiring C1 are connected, the wiring A1 and the wiring C1 are temporarily connected in order to secure workability such as routing of another wiring and connection of another wiring in a limited narrow space. You may want to cancel. In the case of a general well-known electrotap, for example, it is necessary to pry open a closed electrotap with a tool or the like to disconnect the wiring A1 and the wiring C1 from the electrotap to release the connection. On the other hand, in the electrotap 1 of the present embodiment, as shown in FIG. 11(2), the first holding portion 2 holding the wiring A1 and the second holding portion 3 holding the wiring C1 are separated from each other. As a result, the connection between the wirings A1 and C1 can be easily released without prying the electrotap 1 with a tool or the like. In that case, the convex portions 16 and the concave portions 17, and the convex portions 36 and the concave portions 37 are elastically deformed respectively by twisting the first holding portion 2 and the second holding portion 3 in directions opposite to each other. There is a gap. Therefore, the first holding part 2 and the second holding part 3 can be easily separated by pulling apart the first holding part 2 and the second holding part 3 as they are.

By separating the first holding portion 2 and the second holding portion 3 from each other, the first holding portion 2 is connected to the end portion of the wiring A1, and the second holding portion 3 is connected to the end portion of the wiring C1. It becomes a state. Accordingly, the first holding unit 2 can function as the connection terminal of the wiring A1, and the second holding unit 3 can function as the connection terminal of the wiring C1. Further, as shown in FIG. 11A, when the wiring A1 and the wiring C1 are reconnected, the convex portion 16 and the concave portion 17 provided on the separation connection surface 15 of the first holding portion 2 and the second holding portion 3 are provided. The convex portion 36 and the concave portion 37 provided on the separating and connecting surface 35 may be engaged again with each other (see FIG. 3). At this time, since the electrotap 1 returns to the original state, the conduction plate 50 is provided inside the electrotap 1 at the separate connection surfaces 15 and 35 which are mating surfaces of the first holding portion 2 and the second holding portion 3, respectively. The connection surface 51 and the connection surface 61 of the conduction plate 60 are in contact with each other. As a result, the wirings A1 and C1 are electrically connected to each other again via the conduction plates 50 and 60.

The protective cover 70 of the electrotap 1 will be described with reference to FIGS. 9 and 10. As described above, in the present embodiment, the connection between the first holding portion 2 and the second holding portion 3 is made by connecting the convex portion 16 and the concave portion 17 provided on the separation connection surface 15 of the first holding portion 2 formed of resin. Since the structure in which the convex portion 36 and the concave portion 37 provided on the separated connection surface 35 of the second holding portion 3 are engaged with each other is adopted, when a force such as a twist is applied to the connection portion, the convex portion 16 and Since the concave portion 17, the convex portion 36, and the concave portion 37 are elastically deformed respectively, the first holding portion 2 and the second holding portion 3 are easily separated from each other at the connecting portion. Therefore, in the present embodiment, the protective cover 70 may be attached so as to cover the electrotap 1 in a state where the wirings A2 and C2 are held and connected to each other from the outside.

The protective cover 70 is formed, for example, in an inverted U-shape in cross section, but may have any shape as long as it can hold the first holding portion 2 and the second holding portion 3 in the direction in which they are connected to each other. A shape that can cover the electrotap 1 from the upper side to the lower side is preferable. Although the protective cover 70 may be made of any material, it may be made of a material such as rubber or resin having flexibility, as long as it has a certain degree of hardness. The protective cover 70 includes a lateral wall portion 71, a first side wall portion 72, a second side wall portion 73, locking portions 74, 75 and the like. The lateral wall portion 71 is formed in a substantially rectangular plate shape extending in the left-right direction in plan view. The first side wall portion 72 and the second side wall portion 73 are formed in a substantially rectangular plate shape that extends downward from both left and right ends of the lateral wall portion 71 and extends in the vertical direction in side view. The locking portion 74 extends substantially inward from the lower end of the first side wall portion 72 toward the inside (left side). The locking portion 75 extends inwardly (rightward) from the lower end portion of the second side wall portion 73 at a substantially right angle. The respective tip portions of the locking portions 74 and 75 are separated by a predetermined gap.

For example, the operator puts his/her finger on the locking portions 74, 75 of the protective cover 70 and spreads the inside in a V shape, so that the first holding portion 2 of the outer side surface of the electrotap 1 in the closed state. The center portion in the front-rear direction and the center portion in the front-rear direction of the second holding portion 3 are fitted from the outside so as to cover the inside. At this time, the inner surface of the first side wall portion 72 comes into contact with the outer side portion of the first holding portion 2 opposite to the side where the second holding portion 3 is separated and connected. The inner surface of the second side wall portion 73 comes into contact with the outer side portion of the second holding portion 3 opposite to the side where the first holding portion 2 is separated and connected. Therefore, the elastic return force of the protective cover 70 causes the first side wall portion 72 and the second side wall portion 73 to separate the separation connecting surface 15 and the separation connecting surface 35 from the first holding portion 2 and the second holding portion 3. Contact each other in the directions in which they contact each other, so that the first holding portion 2 and the second holding portion 3 can be firmly held integrally. Thereby, even if a force such as a twist is applied to the connecting portion between the first holding portion 2 and the second holding portion 3, it is possible to prevent the connecting portion from coming off easily.

Further, in the outer portion of the first holding portion 2 opposite to the second holding portion 3 side, the connecting portions 27 and 28 are bent in half and project leftward, but the protective cover 70 has Since the first side wall portion 72 is arranged between the connecting portions 27 and 28, the first side wall portion 72 can be brought into close contact with the outer side surface (locking frame portion 25) of the first holding portion 2. On the other hand, on the outer side of the second holding part 3 opposite to the first holding part 2 side, the connecting parts 47 and 48 are bent in half and project rightward, but the protective cover 70 has Since the second side wall portion 73 is arranged between the connecting portions 47 and 48, the second side wall portion 73 can be brought into close contact with the outer surface (locking frame portion 45) of the second holding portion 3. As a result, the first side wall portion 72 and the second side wall portion 73 can be biased to the first holding portion 2 and the second holding portion 3 in close contact with each other in a well-balanced manner in a well-balanced manner. And the 2nd holding part 3 can be hold|maintained more firmly firmly.

Further, in the protective cover 70 attached to the electrotap 1, the locking portions 74 and 75 are in close contact with the side surface portions on the bottom side of the first holding portion 2 and the second holding portion 3, respectively. Thereby, the first holding portion 2 and the second holding portion 3 can be surrounded and held inside, so that the first holding portion 2 and the second holding portion 3 can be held more stably and integrally and firmly.

Further, since the protective cover 70 is formed in a substantially inverted U shape in cross section, it can be attached so as to cover the electrotap 1 in a state of holding the wirings A1 and C1 from the outside. As a result, the protective cover 70 can be freely attached to and detached from the electrotap 1 in the state where the wirings A1 and C1 are held. For example, as will be described later, the electrotap 1 is separated and the holding portion on the other side to which the electrotap 1 is connected is connected. Even after the connection is changed, the protective cover 70 can be easily attached without being affected by the wiring already connected.

With reference to FIGS. 13 to 16, an example of a work method for connecting the product wirings C4 and C5 to the vehicle wiring A3 using the electrotap 150 and 250 will be described. As shown in FIG. 13, the vehicle wiring A3 is, for example, a wiring extending from an ECU (not shown) of an automobile. The product wirings C4 and C5 are, for example, two wirings extending from the external product 80. The external product 80 is, for example, an audio system, a car navigation system, a liquid crystal display, or the like. The vehicle wiring A3 is often arranged, for example, in a dark place in the interior of the automobile, and specifically, such as ECUs under the instrument panel, under the driver's seat, and under the rear of the rear seat. It is often placed at the installation location of the control unit.

As shown in FIG. 13, first, the planned connection portion of the vehicle wiring A3 is cut with scissors or the like. Then, the vehicle wiring A3 is separated into vehicle wirings A4 and A5 at the cut portion. Then, as shown in FIG. 14, the product wiring C4 is connected to one of the vehicle wirings A4 by using the electro-tap 150 as in the connection method described above. The product wiring C5 is connected to the other vehicle wiring A5 using the electrotap 250. Since the electro-tap 150 and 250 are the same as the electro-tap 1 described above, the internal structure will be described with reference to FIG. In the electrotap 150, for example, the first holding unit 152 holds the vehicle wiring A4 and the second holding unit 253 holds the product wiring C4, but the wirings held may be reversed. In the electrotap 250, for example, the first holding unit 252 holds the vehicle wiring A5 and the second holding unit 203 holds the product wiring C5, but the holding wirings may be reversed.

Inside the electro-tap 150, the conductor wire (not shown) of the vehicle wiring A4 contacts the conduction plate 50 (see FIG. 1) in the first holding portion 152, and the conductor wire of the product wiring C4 is inside the second holding portion 253. Of the conductive plate 60 (see FIG. 1). When the connection surface 51 of the conduction plate 50 and the connection surface 61 of the conduction plate 60 contact each other, the vehicle wiring A4 and the product wiring C4 are electrically connected. On the other hand, similarly, inside the electro tap 250, the conductor wire of the vehicle wiring A5 contacts the conduction plate 50 (see FIG. 1) in the second holding portion 202, and the conductor wire of the product wiring C5 is in the second holding portion 203. Of the conductive plate 60 (see FIG. 1). When the connection surface 51 of the conduction plate 50 and the connection surface 61 of the conduction plate 60 contact each other, the vehicle wiring A5 and the product wiring C5 are electrically connected. Although not shown, by attaching the above-mentioned protective covers 70 (see FIGS. 9 and 10) to the electro-tap 150 and 250, respectively, even if a force such as a twist is applied to the connection portion, the first holding portion 152 is provided. , 252 and the second holding portions 153, 253 can be prevented from being separated.

Even in such a connection mode, after the product wirings C4 and C5 are connected to the vehicle wirings A4 and A5, for example, the product wirings C4 and C5 are erroneously connected, and the external product 80 is inspected, repaired, replaced, or the like. In some cases, the external product 80 may be removed and the vehicle wirings A4 and A5 may be reconnected to the original state. If a general well-known electro-tap is used for connection, the worker, for example, sneaks his upper body under the feet of the driver's seat, lays on his back, and puts his hand in the dark space below the steering wheel. The work is extremely difficult because it is necessary to pry open with a tool or the like and to remove the two electro taps from the vehicle wirings A4 and A5 while groping for the two firmly closed electro taps in an unstable posture.

Further, it is conceivable to pry open the two electro taps, remove the product wirings C4 and C5 from the vehicle wirings A4 and A5, and then reconnect the vehicle wirings A4 and A5 with solder or the like. When connecting with solder, the worker must carry out the work while holding the soldering iron in one hand in the above-mentioned unreasonable posture. In that case, it is assumed that the worker looks up from below the vehicle wirings A4 and A5 to be reconnected and solders above the face, for example, in a posture in which he/she dips under the feet of the driver's seat and turns. In that case, in order to ensure safety, it is necessary to work carefully and carefully, for example, using a protective mask that can cover the face. In addition, it is possible to reconnect the vehicle wirings A4 and A5 by making a bullet and the like, but as described above, the vehicle wirings A4 and A5 on the back side under the driver's seat are groped in a groping state. It is extremely difficult to make without skilled skills.

Therefore, the electrotap 150 of the present embodiment can be separated into the first holding part 152 and the second holding part 253, and the electrotap 250 can be separated into the first holding part 252 and the second holding part 203. That is, as shown in FIG. 15, the electrotap 150 can be easily separated into a first holding portion 152 that holds the vehicle wiring A4 and a second holding portion 253 that holds the product wiring C4. On the other hand, the electrotap 250 can be easily separated into a first holding portion 252 that holds the vehicle wiring A5 and a second holding portion 253 that holds the product wiring C5. As a result, even a person who is not familiar with the wiring connection work using the electro-tap can easily remove the product wirings C4 and C5 from the vehicle wirings A4 and A5.

When the product wirings C4 and C5 are removed from the vehicle wirings A4 and A5, the first holding portion 152 is connected to the end of the vehicle wiring A4 in the closed state, and the second end is connected to the end of the product wiring C4. The holding portions 253 are connected in a closed state. On the other hand, the first holding portion 252 is connected to the end of the vehicle wiring A5 in the closed state, and the second holding portion 203 is connected to the end of the product wiring C5 in the closed state. Thus, the first holding portion 152 serves as a connection terminal for the vehicle wiring A4, the second holding portion 253 serves as a connection terminal for the product wiring C4, and the first holding portion 252 serves as a connection terminal for the vehicle wiring A5. The holding portion 203 functions as a connection terminal for the product wiring C5. Since the respective ends of the wirings A4, A5, C4, C5 are covered and protected by the first holding portion 152, the second holding portion 253, the first holding portion 252, and the second holding portion 203, The same function as a well-known electric terminal can be exhibited.

When it is desired to reconnect the vehicle wirings A4 and A5 to the original state, as shown in FIG. 16, a first holding portion 152 that holds the end portion of the vehicle wiring A4 and a first holding portion 152 that holds the end portion of the vehicle wiring A5. The one holding portion 252 may be connected to each other. Here, as shown in FIGS. 1 and 2, the projection 16 and the recess 17 provided on the separation connection surface 15 of the first holding portion 252 of the electrotap 150 and the separation connection surface 35 of the second holding portion 203 are provided. The convex portion 36 and the concave portion 37 provided have the same shape. Therefore, in order to connect the first holding part 152 of the electrotap 150 and the first holding part 252 of the electrotap 250 to each other, for example, the first holding part 252 is placed above and below the first holding part 252. Turn it over and place it. As a result, the concave portion 17 provided on the separating/connecting surface 15 of the first holding portion 252 is made to face the convex portion 16 provided on the separating/connecting surface 15 of the first holding portion 152, and Since the convex portion 16 provided on the separation connecting surface 15 of the first holding portion 252 can be made to face the concave portion 17 provided on the separation connecting surface 15, they can be engaged with each other. With this, as shown in FIG. 16, the first holding unit 152 and the first holding unit 252 can be connected, and thus a new electrotap 350 is configured. Although not shown, inside the electro-tap 350, the connection surface 51 of the conduction plate 50 arranged on the separation connection surface 15 of the first holding portion 152 and the conduction plate arranged on the separation connection surface 15 of the second holding portion 202. The connection surface 51 of 50 contacts each other. As a result, the conductors of the vehicle wirings A4 and A5 are electrically reconnected via the two conduction plates 50, 50.

As described above, in the electrotap 1 of the present embodiment, the wirings can be easily connected and separated from each other, so that the wirings can be easily returned to the original state without any extra work. be able to. Further, since the separation and connection can be repeated any number of times, the wiring work can be easily performed, and the cost of parts such as soldering and gibbous connection can be saved.

In the connection configuration shown in FIG. 14, for example, the vehicle wiring A5 may be held in the second holding portion 253 of the electrotap 250 and the product wiring C5 may be held in the first holding portion 252 of the electrotap 250. When reconnecting the vehicle wirings A4 and A5 in this connection form, the first holding portion 152 of the electrotap 150 holding the vehicle wiring A4 and the second holding portion 253 of the electrotap 250 holding the vehicle wiring A5 are connected. Just connect. In this case, the second holding portion 253 can be directly connected to the first holding portion 152 without changing the posture of the second holding portion 253.

Another usage of the electrotap 1 using the holder 400 will be described with reference to FIGS. 17 to 19. As described above, the electrotap 1 can be separated into the first holding portion 2 and the second holding portion 3. By using such an electro tap 1, for example, as shown in FIG. 17, a holder 400 capable of accommodating the electrical component 500 is sandwiched and connected between the first holding part 2 and the second holding part 3. You can also The electrical component 500 is, for example, a diode, a fuse, or the like.

The structure of the holder 400 will be described. As shown in FIG. 19, the holder 400 is formed in, for example, a substantially rectangular parallelepiped shape, and an upper surface 410 thereof is provided with a storage recess 405 that is recessed downward and has a substantially rectangular shape in a plan view. The electrical component 500 is detachably mounted in the storage recess 405. The holder 400 includes a left side surface 411 and a right side surface 412. The left side surface 411 and the right side surface 412 have a substantially rectangular shape, and for example, the separation connection surface 15 (see FIG. 2) of the first holding portion 2 of the electrotap 1 and the separation connection surface 35 of the second holding portion 3 ( (See FIG. 2) and the length in the front-rear direction is substantially the same. A connection surface 422 of the conducting portion 421, which is connected to the first terminal (not shown) of the electrical component 500, is provided at an approximately central portion of the left side surface 411 of the holder 400 in the front-rear direction. The conducting portion 421 is a conductive member. A convex portion 451 is provided on the rear side of the left side surface 411, and a concave portion 452 is provided on the front side thereof. The convex portion 451 and the concave portion 452 can be engaged with, for example, the concave portion 17 and the convex portion 16 provided on the separation connection surface 15 of the first holding unit 2 shown in FIG.

On the other hand, a connecting surface 432 of the conducting portion 431 connected to the second terminal side (not shown) of the electrical component 500 is exposed at a substantially central portion of the right side surface 412 of the holder 400 in the front-rear direction. The conducting portion 431 is a conductive member. A concave portion 462 is provided on the rear side of the right side surface 412, and a convex portion 461 is provided on the front side thereof. The convex portion 461 and the concave portion 462 can be engaged with the convex portion 36 and the concave portion 37 provided on the separation connection surface 35 of the second holding portion 3 shown in FIG. 2, for example.

-When a fuse is used as the electrical component 500-
For example, as shown in FIGS. 17 and 20, the electrotap 1 that connects the wirings A6 and C6 is separated into a first holding portion 2 and a second holding portion 3, and an electrical component 500, which is a fuse, is provided between them. The mounted holder 400 is connected. Note that, in FIG. 20, the first holding portion 2 and the second holding portion 3 are illustrated in an open state in order to make the internal structure and the connecting portion easy to see. In this case, by engaging the convex portion 451 and the concave portion 452 provided on the left side surface 411 of the holder 400 with the concave portion 17 and the convex portion 16 provided on the separation connection surface 15 of the first holding portion 2, the wiring A6 is obtained. A fuse can be easily connected between C6 and C6. As a result, the electrotap 1 with a fuse can be easily manufactured. Since a fuse can be easily connected between the first holding unit 2 and the second holding unit 3, for example, it is possible to prevent a current higher than the rated value from flowing between the wirings A6 and C6. Further, since the fuse can be arranged between the first holding portion 2 and the second holding portion 3, it is possible to prevent a current exceeding the rated value from flowing through the wiring A6 or the wiring C6 when a short circuit occurs. Further, when a short circuit occurs, it is only necessary to replace the electrical component 500 mounted on the holder 400, so that a troublesome work such as connecting a new wiring for connecting a new fuse can be eliminated. Further, since it can be handled as an electro-tap 1 with a fuse, no extra wiring or the like for connecting the fuse is required, so that the number of parts and the parts cost can be reduced. Further, since it is only necessary to connect the holder 400 on which the electrical component 500 is mounted between the first holding portion 2 and the second holding portion 3, a new wiring for connecting a fuse is attached to one wiring. No need for troublesome work.

-When a diode is used as the electrical component 500-
For example, there is a case where there is only one courtesy wiring connected to an ECU of an automobile or the like, and the product wiring of a courtesy device (not shown) attached to each of the four vehicle doors is branched from the one wiring. .. In this case, as shown in FIG. 18, it is necessary to dispose a diode for flowing a current from the product wiring C7 side to the courtesy wiring A7 side between the courtesy wiring A7 and the product wiring C7 in each door. In this case, for example, by connecting the holder 400 mounted in the storage recess 405 with the diode as the electric component 500 between the first holding portion 2 and the second holding portion 3 of the electrotap 1, the diode-equipped electrotap is provided. 1 can be easily manufactured. By connecting the electro-tap 1 incorporating such a diode between the courtesy wiring A7 and the product wiring C7, for example, the courtesy devices provided on the four vehicle doors are not electrically connected to each other. Can be dealt with. As a result, the ECU can receive the signals output from the courtesy devices provided on the vehicle doors, respectively, and thus can accurately recognize which vehicle door is open.

In the present embodiment, there is only one courtesy wiring connected to the ECU of the automobile, etc., and the product wiring of the courtesy device (not shown) that is branched from one and attached to each of the four vehicle doors is provided. When connecting, the electrical component 500, which is a diode, is attached to the holder 400, and the example in which the holder 400 is connected between the courtesy wiring A7 and the product wiring C7 has been described, but the type of wiring is not limited and other than this. It goes without saying that the holder 400 having the electrical component 500, which is a diode, can be connected between the wirings of the above type.

Further, in the present embodiment, the holder 400 to which the electric component 500, which is a fuse or a diode, can be removably mounted has been described. However, for example, the electric component 500 may be provided between the first holding unit 2 and the second holding unit 3. It may be directly sandwiched and connected. In that case, the convex portion 451 and the concave portion 452 provided on the left side surface 411 of the holder 400 are provided on one side surface of the electrical component 500, and the convex portion 461 provided on the right side surface 412 of the holder 400 is provided on the opposite side surface. The recess 462 may be provided. In that case, the fuse or the diode can be directly sandwiched between the first holding portion 2 and the second holding portion 3 to be connected.

As described above, in the electrotap 1 of the present embodiment, the wirings A1 and C1 are sandwiched and held, and the wirings A1 and C1 are clamped by the force when the wirings A1 and C1 are sandwiched, respectively. Is a wiring connecting member that electrically connects the wirings A1 and C1 by electrically connecting the conductive plate 50 and the conductive plate 60 that are in contact with the conductive wires 101A and 102A in the coatings 101B and 102B of C1 and C1, respectively. .. The electrotap 1 can be separated and connected to the first holding part 2 that holds the wiring A1 in between and the second holding part 3 that holds the wiring C1 in between. When the first holding unit 2 and the second holding unit 3 are connected to each other, the conduction plate 50 provided on the first holding unit 2 and the conduction plate 60 provided on the second holding unit 3 are electrically connected to each other. By connecting, the wiring A1 and the wiring C1 are electrically connected. In this way, the electrotap 1 can separate the first holding part 2 holding the wiring A1 and the second holding part 3 holding the wiring C1 from each other, and therefore it is necessary to remove the wirings A1 and C2 from the electrotap 1. There is no. Therefore, it is possible to facilitate the work while diving in a narrow place, particularly in the dark place of the vehicle interior, and to perform the work by groping. Then, by reconnecting the separated first holding unit 2 and second holding unit 3, the conduction plate 50 connected to the conductor 101A of the wiring A1 and the conduction plate 60 connected to the conductor 102A of the wiring C1 are electrically connected. Since they are electrically connected, the wiring A1 and the wiring C1 can be electrically reconnected. Therefore, the first holding unit 2 can function as a terminal connected to the wiring A1, and the second holding unit 3 can function as a terminal connected to the wiring C1. Therefore, it is possible to completely eliminate the troublesome work of using the tool such as reattaching the wirings A1 and C1 with solder, forming a pit and reconnecting.

It should be noted that the present invention is not limited to the above-described embodiment, and various modifications can be made. In the following, eight modified examples in which the electrotap 1 of the above embodiment is modified will be sequentially described. It should be noted that portions having the same structure will be described using the same reference numerals.

A first modification will be described with reference to FIG. The electrotap 101 which is the first modification is a modification of the part of the electrotap 1 (see FIG. 1) of the above embodiment, which is separately connected to the first holding part 2 and the second holding part 3. The electrotap 101 can be separately connected to the first holding part 121 and the second holding part 131. The separation connecting surface 15 of the first holding portion 2 of the above embodiment is provided with one convex portion 16 and one concave portion 17, and the separation connecting surface 35 of the second holding portion 3 is provided with a convex portion 36 and a concave portion 37.

On the other hand, two protrusions 16 and two recesses 17 are provided on the separation connection surface 15 of the first holding portion 121 of the first modification, and the separation connection surface 35 of the second holding portion 131 has a protrusion portion. Two 36 and two recesses 37 are provided. In detail, in the separated connection surface 15, a set of the convex portion 16 and the recess portion 17 is provided in each of the regions of the conduction plate 50 on the front side and the rear side of the connection surface 51. Further, in each area, the convex portion 16 is arranged on the connection surface 51 side. On the other hand, in the separated connection surface 35, a pair of the projections 36 and the recesses 37 are provided in each of the regions of the conduction plate 60 on the front side and the rear side of the connection surface 61. Further, in each region, the recess 37 is arranged on the connection surface 61 side.

Then, the two convex portions 16 and the two concave portions 17 provided on the separating/connecting surface 15 and the two concave portions 37 and the two convex portions 36 provided on the separating/connecting surface 35 are engaged with each other. The one holding part 121 and the second holding part 131 can be connected to each other. In the first modified example, the number of the convex portions 16 and 36 and the concave portions 17 and 37 that connect the separating and connecting surfaces 15 and 35 is larger than that in the above-described embodiment, so that the first holding portion 121 and the second holding portion 131 are included. Can be firmly connected. Further, in the separate connection surfaces 15 and 35, the convex portion 16 and the concave portion 37 engage with each other and the convex portion 36 and the concave portion 37 engage with each other on the front side and the rear side with the connection surfaces 51 and 61 as a boundary. 35 can be fixed in good balance. As described above, since the electrotap 101 of the first modified example can be separately connected to the first holding part 121 and the second holding part 131 as in the above-described embodiment, the same effect as that of the above-described embodiment can be obtained. Obtainable. In addition, in the first modified example, two protrusions 16 and two recesses 17 are provided on the separation/connection surface 15, and two protrusions 36 and two recesses 37 are provided on the separation/connection surface 35. You may provide one or more. Further, one or a plurality of protrusions 16 may be provided on the separation/connection surface 15, and one or a plurality of recesses 37 may be provided on the separation/connection surface 35. The protective cover 70 shown in FIG. 9 may be attached to the electrotap 101 in which the first holding part 121 and the second holding part 131 are connected.

A second modification will be described with reference to FIG. The electrotap 102 which is the second modification is also a modification of the part of the electrotap 1 (see FIG. 1) of the above embodiment, which is separately connected to the first holding part 2 and the second holding part 3. The electrotap 102 can be separately connected to the first holding part 122 and the second holding part 132. The separation connecting surface 15 of the first holding portion 2 of the above embodiment is provided with one convex portion 16 and one concave portion 17, and the separation connecting surface 35 of the second holding portion 3 is provided with a convex portion 36 and a concave portion 37. They are provided one by one (see FIG. 2). On the other hand, the separation connection surface 15 of the first holding portion 122 of the second modified example is provided with the two convex portions 160, and the separation connection surface 35 of the second holding portion 132 is provided with the two projection portions 160. Correspondingly, two recesses 370 are provided. The shapes of the convex portion 160 and the concave portion 370 may be, for example, shapes that can be slidably inserted and fixed in the vertical direction. Further, the convex portion 160 has a height from the upper end of the separation connection surface 15 to a position separated from the lower end by a predetermined distance. Therefore, the bottom surface of the convex portion 160 is arranged at a position higher than the lower end of the separation connection surface 15 by a predetermined distance. The concave portion 370 also has a height from the upper end of the separation connection surface 35 to a position separated from the lower end by a predetermined distance. Therefore, the bottom surface 370A is formed in the lower portion of the recess 370. The bottom surface 370A is arranged at a position higher than the lower end of the separation connection surface 35 by a predetermined distance.

Then, for example, the two protrusions 160 provided on the separating/connecting surface 15 are slid and inserted into the two recesses 370 provided on the separating/connecting surface 35 from above. Then, since the bottom surface of each convex portion 160 contacts the bottom surface 370A of each concave portion 370, the two convex portions 160 engage with the two concave portions 370. In this state, by closing the second lid part 8 of the second holding part 132 with respect to the second base part 7, the outer upper surface part 43 of the second lid part 8 causes the outer upper surface part 32 of the second base part 7.
