The connecting portions 47 and 48 are formed in the shape of an elongated substantially rectangular plate 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 in the plate groove 31A provided in the support wall 38, the groove 31, and the outer upper surface portion 32. Metal can also be used for the conduction plate 60, but any member having conductivity may 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 in front view. The conduction plate 60 includes a groove 62 at the upper end thereof. The groove portion 62 is recessed downward from a position corresponding to the groove 31 at the upper end portion of the conduction plate 60 in a substantially U-shape, and the position slightly above the inner surface of the groove 31 is the bottom portion. Since both corners on the upper side of the groove 62 have an arcuate taper, it is easy to draw the wiring C1 into the inside of the groove 62. The groove width (length in the left-right direction) of the groove portion 62 is separated by a width smaller than the diameter of the wiring C1, but for example, even if the diameter of the bundle of the conducting wires 102A excluding the coating 102B of the wiring C1 is substantially the same. good. Further, the groove width of the groove portion 62 is the same from top to bottom, but for example, the width may be gradually narrowed from top to bottom.

An example of a wiring connection method using the electro tap 1 will be described with reference to FIGS. 1 to 8. Here, as shown in FIG. 11 (1), the most basic connection form for connecting the wiring A1 and the wiring C1 will be described as an example. As shown in FIGS. 3 and 8, the wiring A1 is a general one in which the periphery of the conductor 101A is covered with a coating 101B. The wiring C1 is a general one in which the circumference of the conductor 102A is covered with the 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 portion of the wiring A1 on the protrusion 26, it is possible to prevent the wiring A1 from protruding to the outside of the electro tap 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 to the outside of the electro tap 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 the arrow P1 in the drawing to close the first lid portion 6. When the first lid portion 6 is rotated by approximately 90 ° with respect to the first base portion 5, as shown in FIG. 6, the locking frame portion 25 of the first lid portion 6 becomes substantially horizontal and the upper end thereof becomes substantially horizontal. 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 in the central portion 212 of the first base portion 5. On the other hand, by pressing 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 members, the first lid portion 6 and the first base portion 5 are relative to each other. Easy to apply force. At this time, the coating 101B of the wiring A1 is tightened by the inner edge portion of the groove portion 52 and is torn, 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 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 portion 8 is rotated with respect to the second base portion 7 in the direction of arrow P2 in FIG. 5 to close the second lid portion 8. Similar to the first holding portion 2, when the second lid portion 8 is rotated by approximately 90 ° with respect to the second base portion 7, the locking frame portion 45 of the second lid portion 8 becomes substantially horizontal and at the same time. The upper end thereof 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 toward the second base portion 7, 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 in the central portion 312 of the second base portion 7. On the other hand, by pressing from above, the wiring C1 is pushed downward along the groove portion 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 members, the second lid portion 8 and the second base portion 7 are relative to each other. Easy to apply force. At this time, the coating 102B of the wiring C1 is tightened by the inner edge portion of the groove portion 62 and is torn, so that the conduction plate 60 comes into contact with the conducting wire 102A of the wiring C1. Then, as shown in FIG. 7, when the locking frame portion 45 slides down the peripheral surface of the conical portion 39, the bottom portion of the conical portion 39 is locked inside the locking frame portion 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 continuity plate 50 is in contact with the conductor 101A of the wiring A1, and the continuity plate 60 is in contact with the conductor 102A of the wiring C1. Further, at the separated connecting surfaces 15 and 35, which are the mating surfaces of the first holding portion 2 and the second holding portion 3, the connecting surface 51 of the conduction plate 50 and the connecting surface 61 of the continuity plate 60 come into contact with each other. It constitutes one conductive member (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 coating 101B is broken, so that the conducting wire 101A and the inner edge portion of the groove portion 52 are in contact with each other. Since the conduction plate 50 is arranged so as to be orthogonal to the wiring A1, at the portion where the conducting wire 101A and the inner edge portion of the groove portion 52 come into contact with each other, a substantially ring-shaped cut end of the cut coating 101B is formed. However, the conductive plate 50 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. As a result, even if the wiring A1 is pulled forward, it is possible to prevent the wiring A1 from being pulled out. This also applies to the wiring C1 inside the second holding portion 3.

A method of disconnecting the wirings A1 and C1 in the electro tap 1 will be described with reference to FIGS. 2 and 11. After connecting the wiring A1 and the wiring C1, for example, in a limited narrow space, the wiring A1 and the C1 are once connected for the purpose of ensuring workability such as handling other wiring and connecting the other wiring. You may want to cancel it. In the case of a generally well-known electro tap, for example, it is necessary to pry open the closed electro tap with a tool or the like, remove the wiring A1 and the wiring C1 from the electro tap, and disconnect the connection. On the other hand, in the electro tap 1 of the present embodiment, as shown in FIG. 11 (2), the first holding portion 2 that holds the wiring A1 and the second holding portion 3 that holds the wiring C1 are separated from each other. As a result, the connection between the wirings A1 and C1 can be easily disconnected without prying open the electro tap 1 with a tool or the like. In that case, by twisting the first holding portion 2 and the second holding portion 3 in opposite directions, for example, the convex portion 16 and the concave portion 17, the convex portion 36 and the concave portion 37 are elastically deformed. There will be a gap. Therefore, by separating the first holding portion 2 and the second holding portion 3 as they are, the first holding portion 2 and the second holding portion 3 can be easily separated.

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. As a result, the first holding portion 2 can function as a connection terminal for the wiring A1, and the second holding portion 3 can function as a connection terminal for the wiring C1. Further, as shown in FIG. 11 (1), when the wiring A1 and the wiring C1 are reconnected, the convex portion 16 and the concave portion 17 provided on the separated connection surface 15 of the first holding portion 2 and the second holding portion 3 are further connected. The convex portion 36 and the concave portion 37 provided on the separation connection surface 35 of the above may be engaged with each other again (see FIG. 3). At this time, since the electro tap 1 returns to the original state, the continuity plate 50 is formed inside the electro tap 1 on the separated connecting 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 above and the connection surface 61 of the continuity 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 electro tap 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 connected to the convex portion 16 and the concave portion 17 provided on the separation connecting surface 15 of the first holding portion 2 made of resin. Since the structure is adopted in which the convex portion 36 and the concave portion 37 provided on the separated connecting surface 35 of the second holding portion 3 are engaged with each other, when a force such as a twist is applied to the connecting portion, the convex portion 16 and the concave portion 37 and the concave portion 37 are engaged with each other. Since the concave portion 17, the convex portion 36 and the concave portion 37 are each elastically deformed, the first holding portion 2 and the second holding portion 3 are likely to come off at the connecting portion. Therefore, in the present embodiment, the protective cover 70 can be attached so as to cover the electro tap 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 a substantially 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 a direction in which they are connected to each other. A shape that can cover the electro tap 1 so as to wrap around from the upper side to the lower side is preferable. The material of the protective cover 70 may be any material, as long as it has a certain degree of hardness, and may be formed of, for example, a flexible material such as rubber or resin. The protective cover 70 includes a side wall portion 71, a first side wall portion 72, a second side wall portion 73, locking portions 74, 75 and the like. The side wall portion 71 is formed in a substantially rectangular plate shape extending in the left-right direction in a plan view. The first side wall portion 72 and the second side wall portion 73 extend downward from the left and right end portions of the side wall portion 71, respectively, and are formed in a substantially rectangular plate shape extending in the vertical direction in the side view. The locking portion 74 extends inward (to the left) from the lower end of the first side wall portion 72 at a substantially right angle. The locking portion 75 extends inward (to the right) from the lower end of the second side wall portion 73 at a substantially right angle. The tips of the locking portions 74 and 75 are separated from each other with a predetermined gap.

For example, the operator puts his finger on the locking portions 74 and 75 of the protective cover 70 and spreads the inside in a V shape so that the first holding portion 2 of the outer surface of the closed electro tap 1 is formed. The central portion in the front-rear direction and the central portion in the front-rear direction of the second holding portion 3 are fitted inward so as to cover the central portion in the front-rear direction from the outside. At this time, the inner surface of the first side wall portion 72 comes into contact with the outer portion on the side opposite to the side that is separately connected to the second holding portion 3 of the first holding portion 2. The inner surface of the second side wall portion 73 comes into contact with the outer portion on the side opposite to the side that is separately connected to the first holding portion 2 of the second holding portion 3. Therefore, due to the elastic return force of the protective cover 70, the first side wall portion 72 and the second side wall portion 73 have the separate connection surface 15 and the separate connection surface 35 with respect to the first holding portion 2 and the second holding portion 3. Are in contact with each other in the directions of contact with each other, so that the first holding portion 2 and the second holding portion 3 can be integrally and firmly held. As a result, 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 can be prevented from coming off.

Further, on the outer side 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 to the left side, but the protective cover 70 is provided. 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 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 to the right side, but the protective cover 70 Since the second side wall portion 73 is arranged between the connecting portions 47 and 48, it 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 urged in close contact with each other in a well-balanced manner with respect to the first holding portion 2 and the second holding portion 3, so that the first holding portion 2 can be urged. And the second holding portion 3 can be held more integrally and firmly.

Further, in the protective cover 70 attached to the electro tap 1, the locking portions 74 and 75 are in close contact with the side surface portions on the bottom side of each of the first holding portion 2 and the second holding portion 3. As a result, the first holding portion 2 and the second holding portion 3 can be surrounded from the surroundings and held inward, so that the first holding portion 2 and the second holding portion 3 can be held more stably, 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 electro tap 1 in a state where the wirings A1 and C1 are held from the outside. As a result, the protective cover 70 can be freely attached to and detached from the electro tap 1 in which the wirings A1 and C1 are held. Therefore, for example, as described later, the holding portion on the other side to separate and connect the electro tap 1 is separated. The protective cover 70 can be easily attached without being affected by the wiring already connected even after the connection is changed.

With reference to FIGS. 13 to 16, an example of a working method in which the product wirings C4 and C5 are connected to the vehicle wiring A3 by using the electro taps 150 and 250 will be described. As shown in FIG. 13, the vehicle wiring A3 is, for example, wiring extending from an automobile ECU (not shown). 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 in a dark place in the passenger compartment of an automobile, for example, specifically, an ECU or the like located under the instrument panel, under the driver's seat, or behind the rear seat. It is often located at the installation location of the control unit, etc.

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 the vehicle wiring 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 in the same manner as in the above connection method. The product wiring C5 is connected to the other vehicle wiring A5 by using the electro tap 250. Since the electro taps 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 electro tap 150, for example, the first holding portion 152 holds the vehicle wiring A4 and the second holding portion 253 holds the product wiring C4, but the holding wiring may be reversed. In the electro tap 250, for example, the first holding portion 252 holds the vehicle wiring A5 and the second holding portion 203 holds the product wiring C5, but the holding wiring may be reversed.

Inside the electrotap 150, the conductor of the vehicle wiring A4 (not shown) comes into contact with the conduction plate 50 (see FIG. 1) in the first holding portion 152, and the conductor of the product wiring C4 is in the second holding portion 253. Contact the conduction plate 60 (see FIG. 1). The vehicle wiring A4 and the product wiring C4 are electrically connected by the contact between the connection surface 51 of the continuity plate 50 and the connection surface 61 of the continuity plate 60. On the other hand, similarly inside the electrotap 250, the conductor of the vehicle wiring A5 is in contact with the conduction plate 50 (see FIG. 1) in the second holding portion 202, and the conductor of the product wiring C5 is in the second holding portion 203. Contact the conduction plate 60 (see FIG. 1). The vehicle wiring A5 and the product wiring C5 are electrically connected by the contact between the connection surface 51 of the continuity plate 50 and the connection surface 61 of the continuity plate 60. Although not shown, by attaching the above protective covers 70 (see FIGS. 9 and 10) to the electro taps 150 and 250, even if a force such as a twist is applied to the connection portion, the first holding portion 152 , 252 and the second holding portions 153, 253 can be prevented from being separated.

By the way, even in such a connection form, after connecting the product wirings C4 and C5 to the vehicle wirings A4 and A5, for example, the reason is that the product wirings C4 and C5 are erroneously connected, and the external product 80 is inspected, repaired or replaced. As a result, there is a case where it is desired to remove the external product 80 and reconnect the vehicle wirings A4 and A5 to the original state. If connected using a well-known electro-tap, the operator would, for example, sneak into the feet of the driver's seat, lie on his back, and put his hand in the dark space under the steering wheel. In an unstable posture, it is necessary to pry open the two tightly closed electro taps with a tool or the like and remove the two electro taps from the vehicle wirings A4 and A5, which makes the work extremely difficult.

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 will work with the soldering iron in one hand in the above-mentioned unreasonable posture. In that case, it is assumed that the worker looks up at the vehicle wirings A4 and A5 to be reconnected from below and solders them above the face, for example, in a posture of sneaking into the feet of the driver's seat and facing. In that case, in order to ensure safety, it is necessary to work carefully and carefully, for example, by using a protective mask that can cover the face. In addition, it is conceivable to reconnect the vehicle wiring A4 and A5 by making a giboshi, but as mentioned above, the giboshi is groped for the vehicle wiring A4 and A5 on the back side under the driver's seat. It is extremely difficult to make without skilled skills.

Therefore, the electrotap 150 of the present embodiment can be separated into the first holding portion 152 and the second holding portion 253, and the electrotap 250 can be separated into the first holding portion 252 and the second holding portion 203. That is, as shown in FIG. 15, the electro tap 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 electro tap 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 accustomed to 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 a closed state, and the second is connected to the end of the product wiring C4. The holding portions 253 are connected to each other in a closed state. On the other hand, the first holding portion 252 is connected to the end of the vehicle wiring A5 in a closed state, and the second holding portion 203 is connected to the end of the product wiring C5 in a closed state. As a result, the first holding portion 152 serves as a connection terminal for the vehicle wiring A4, the second holding portion 253 serves as a connecting terminal for the product wiring C4, and the first holding portion 252 serves as a connecting terminal for the vehicle wiring A5. The holding portion 203 functions as a connection terminal for the product wiring C5. Since each end of the wiring A4, A5, C4, C5 is 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, it is general. It can exhibit the same function as a well-known electric terminal.

Then, 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 for holding the end portion of the vehicle wiring A4 and a second holding portion 152 for holding the end portion of the vehicle wiring A5. (1) The holding portions 252 may be connected to each other. Here, as shown in FIGS. 1 and 2, the convex portion 16 and the concave portion 17 provided on the separate connection surface 15 of the first holding portion 252 of the electro tap 150 and the separate connection surface 35 of the second holding portion 203. The convex portion 36 and the concave portion 37 provided have the same shape as each other. Therefore, in order to interconnect the first holding portion 152 of the electro tap 150 and the first holding portion 252 of the electro tap 250, for example, the first holding portion 252 is moved above and below the first holding portion 152. Just turn it over and place it. As a result, the concave portion 17 provided on the separated connection surface 15 of the first holding portion 252 is made to face the convex portion 16 provided on the separated connecting surface 15 of the first holding portion 152, and the first holding portion 152 is formed. Since the convex portion 16 provided on the separate connection surface 15 of the first holding portion 252 can be made to face the concave portion 17 provided on the separate connection surface 15, each can be engaged with each other. As a result, as shown in FIG. 16, since the first holding portion 152 and the first holding portion 252 can be connected, a new electro tap 350 is configured. Although not shown, inside the electrotap 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 continuity plate arranged on the separation connection surface 15 of the second holding portion 202. The connecting surfaces 51 of 50 come into contact with each other. As a result, the respective conductors of the vehicle wirings A4 and A5 are electrically reconnected via the two conduction plates 50, 50.

As described above, since the electro tap 1 of the present embodiment can easily connect and separate the wirings, the wirings can be easily returned to the original original state without any extra work and trouble. be able to. In addition, since the separation and connection can be repeated as many times as necessary, the wiring work can be easily performed, and the cost of parts for soldering, giboshi connection, etc. can be saved.

In the connection mode shown in FIG. 14, for example, the vehicle wiring A5 may be held by the second holding portion 253 of the electro tap 250, and the product wiring C5 may be held by the first holding portion 252 of the electro tap 250. When the vehicle wiring A4 and A5 are reconnected in this connection form, the first holding portion 152 of the electro tap 150 that holds the vehicle wiring A4 and the second holding portion 253 of the electro tap 250 that holds the vehicle wiring A5 are connected. Just connect. In this case, it can be connected to the first holding portion 152 as it is without changing the posture of the second holding portion 253.

17 to 19, another method of using the electro tap 1 using the holder 400 will be described. As described above, the electro tap 1 can be separated into a first holding portion 2 and a second holding portion 3. Using such an electro tap 1, for example, as shown in FIG. 17, a holder 400 capable of accommodating an electrical component 500 is sandwiched and connected between the first holding portion 2 and the second holding portion 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, for example, in a substantially rectangular parallelepiped shape, and the upper surface 410 thereof is provided with a storage recess 405 having a substantially rectangular shape in a plan view, which is recessed downward. The electrical component 500 is detachably attached to 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 are, for example, a separated connection surface 15 (see FIG. 2) of the first holding portion 2 of the electro tap 1 and a separated connecting surface 35 of the second holding portion 3 (see FIG. 2). Each of them has substantially the same length as the length in the anteroposterior direction (see FIG. 2). The connection surface 422 of the conduction portion 421 connected to the first terminal (not shown) of the electrical component 500 is exposed and provided at the substantially central portion of the left side surface 411 of the holder 400 in the front-rear direction. The conductive 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. The convex portion 451 and the concave portion 452 can be engaged with the concave portion 17 and the convex portion 16 provided on the separation connecting surface 15 of the first holding portion 2 shown in FIG. 2, for example.

On the other hand, the connection surface 432 of the conduction portion 431 connected to the second terminal side (not shown) of the electrical component 500 is exposed and provided at the substantially central portion of the right side surface 412 of the holder 400 in the front-rear direction. The conductive 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. 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 connecting surface 35 of the second holding portion 3 shown in FIG. 2, for example.

-When using a fuse as an electrical component 500-
For example, as shown in FIGS. 17 and 20, the electro tap 1 connecting 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 inserted between them. Connect the mounted holder 400. In addition, in FIG. 20, in order to show the internal structure and the connecting portion in an easy-to-understand manner, the first holding portion 2 and the second holding portion 3 are shown in an open state. In this case, the wiring A6 is made 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 separate connection surface 15 of the first holding portion 2. A fuse can be easily connected between and C6. As a result, the electro tap 1 containing a fuse can be easily manufactured. Since the fuse can be easily connected between the first holding portion 2 and the second holding portion 3, for example, it is possible to prevent a current exceeding the rating 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 rating from flowing through the wiring A6 or the wiring C6 in the event of a short circuit. Further, in the case of a short circuit, it is only necessary to replace the electrical component 500 mounted on the holder 400, so that 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 containing a fuse, extra wiring for connecting the fuse is not required, so that the number of parts and the cost of parts can be reduced. Further, since it is only necessary to connect the holder 400 to which the electrical component 500 is mounted between the first holding portion 2 and the second holding portion 3, a new wiring for connecting the fuse to one of the wirings is attached. It is possible to eliminate troublesome work such as.

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

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

Further, in the present embodiment, the holder 400 to which the electrical component 500 which is a fuse or the diode can be detachably mounted has been described. For example, the electrical component 500 is placed between the first holding portion 2 and the second holding portion 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. And the recess 462 may be provided. In that case, a fuse or a diode can be directly sandwiched and connected between the first holding portion 2 and the second holding portion 3.

As described above, the electro tap 1 of the present embodiment sandwiches and holds the wirings A1 and C1, respectively, and tightens the wirings A1 and C1 by the force when sandwiching the wirings A1 and C1, respectively, and the wiring A1. This is a wiring connection member that electrically connects the wirings A1 and C1 by electrically connecting the conduction plate 50 and the continuity plate 60, which are in contact with the conductors 101A and 102A in the coatings 101B and 102B of C1. .. The electro tap 1 can be separated and connected to the first holding portion 2 that sandwiches and holds the wiring A1 and the second holding portion 3 that sandwiches and holds the wiring C1. When the first holding portion 2 and the second holding portion 3 are connected to each other, the conduction plate 50 provided in the first holding portion 2 and the continuity plate 60 provided in the second holding portion 3 are electrically connected to each other. By connecting, the wiring A1 and the wiring C1 are electrically connected. In this way, the electro tap 1 can separate the first holding portion 2 that holds the wiring A1 and the second holding portion 3 that holds the wiring C1 from each other, so that it is necessary to remove the wirings A1 and C2 from the electro tap 1. There is no. Therefore, it is possible to facilitate work while diving in a narrow space, especially in a dark place in a vehicle interior, and even to work by groping. Then, by reconnecting the first holding portion 2 and the second holding portion 3 after separation, 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. Wiring A1 and wiring C1 can be electrically reconnected. Therefore, the first holding portion 2 can function as a terminal connected to the wiring A1, and the second holding portion 3 can function as a terminal connected to the wiring C1. Therefore, it is possible to eliminate the troublesome work of using a tool, such as re-soldering the wirings A1 and C1 or making a giboshi and reconnecting them.

Below, eight modification examples of the modification of the electro tap 1 of the above embodiment will be described in order. The parts having a common structure will be described using the same reference numerals.

The first modification will be described with reference to FIG. 21. The electrotap 101, which is a first modification, is a modification of the portion of the electrotap 1 (see FIG. 1) of the above embodiment that is separated and connected to the first holding portion 2 and the second holding portion 3.

They are provided one by one (see Fig. 2). On the other hand, the separated connection surface 15 of the first holding portion 122 of the second modification is provided with two convex portions 160, and the separated connecting surface 35 of the second holding portion 132 has two convex portions 160. Two recesses 370 are provided to correspond. The shape of the convex portion 160 and the concave portion 370 may be, for example, a shape 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 separated connection surface 15 to a position separated from the lower end by a predetermined distance.
