[0017] Furthermore, the connector 1 includes a first fuse 41 and a second fuse 42 that are disposed within the connector circuit 10 (FIGS. 2 to 4). The connector 1 also includes a bus bar 43 that is fixed to one end of each of the first fuse 41 and the second fuse 42 with a screw to electrically connect the one ends of the first fuse 41 and the second fuse 42 to each other (FIGS. 2 to 4).
[0018] The first fuse 41 and the second fuse 42 are formed in an axial shape with electrical connection portions at one end and the other end of the axial direction. The first fuse 41 and the second fuse 42 illustrated here are so-called tube fuses.
[0019] The first fuse 41 has a first terminal 41a at one end and a second terminal 41b at the other end (FIGS. 2 and 3). The first terminal 41a is formed in a flat plate shape and is physically and electrically connected to a base at one end of a tubular fuse body 41x. The first terminal 41a has a through hole 41c with a hole axis perpendicular to the axial direction of the first fuse 41 (FIG. 3). The second terminal 41b is formed in a flat plate shape on the same plane as the first terminal 41a and is physically and electrically connected to a base at the other end of the fuse body 41x. The second terminal 41b has a through hole 41d with a hole axis perpendicular to the axial direction of the first fuse 41 (FIG. 3). The through holes 41c and 41d have their hole axes oriented in the same direction.
[0020] The second fuse 42 has a first terminal portion 42a at one end and a second terminal portion 42b at the other end (FIGS. 2 and 3). The first terminal portion 42a is formed in a flat plate shape and is physically and electrically connected to a base at one end of a tubular fuse body 42x. The first terminal portion 42a has a through hole 42c with a hole axis perpendicular to the axial direction of the second fuse 42 (FIG. 3). The second terminal portion 42b is formed in a flat plate shape on the same plane as the first terminal portion 42a and is physically and electrically connected to a base at the other end of the fuse body 42x. The second terminal portion 42b has a through hole 42d with a hole axis perpendicular to the axial direction of the second fuse 42 (FIG. 3). The through holes 42c and 42d have their hole axes oriented in the same direction.
[0021] The first fuse 41 and the second fuse 42 may be the same component having the same shape and capacity, or may be different components having the same shape but different capacity.
[0022] Bus bar 43 is made of a conductive material such as metal. A first through hole 43a is formed in bus bar 43, which is arranged coaxially with through hole 41c at one end of first fuse 41, and a second through hole 43b is formed in bus bar 43, which is arranged coaxially with through hole 42c at one end of second fuse 42 (FIG. 3). Bus bar 43 shown here is, for example, a plate-shaped press-molded product using a metal plate as a base material.
[0023] The connector 1 includes a housing 50 in which the electric wire with a first terminal 11, the electric wire with a second terminal 12, the electric wire with a third terminal 13, the electric wire with a fourth terminal 14, the electric wire with a fifth terminal 15, the electric wire with a sixth terminal 16, the first fuse 41, the second fuse 42, and the bus bar 43 are accommodated in an accommodating chamber 50a, and a cover 60 that closes an opening 50b of the accommodating chamber 50a (FIGS. 1 to 4). In the housing 50, the first fuse 41 and the like are inserted into the accommodating chamber 50a through the opening 50b. The housing 50 and the cover 60 are molded from an insulating material such as synthetic resin. An annular packing 65 is provided between the housing 50 and the cover 60 to prevent liquids such as water from entering the accommodating chamber 50a through the gap between them (FIGS. 2 to 4).
[0024] Housing 50 has an annular side wall portion 51 and a blocking portion 52 that blocks an opening at one axial end of side wall portion 51 (FIGS. 1 to 4). In this housing 50, the space surrounded by side wall portion 51 and blocking portion 52 is used as storage chamber 50a, and the opening at the other axial end of side wall portion 51 is used as opening 50b of storage chamber 50a.
[0025] The first fuse 41 shown here is accommodated in the accommodation chamber 50a with its fuse body 41x facing the opening 50b (FIG. 3). The second fuse 42 shown here is accommodated in the accommodation chamber 50a with its fuse body 42x facing the bottom wall of the accommodation chamber 50a (FIG. 3). However, in the housing 50, the first fuse 41 may be accommodated in the accommodation chamber 50a with its fuse body 41x facing the bottom wall of the accommodation chamber 50a, and the second fuse 42 may be accommodated in the accommodation chamber 50a with its fuse body 42x facing the opening 50b. In the housing 50, the first fuse 41 and the second fuse 42 may be accommodated in the accommodation chamber 50a with their respective fuse bodies 41x and 42x facing the opening 50b, or the first fuse 41 and the second fuse 42 may be accommodated in the accommodation chamber 50a with their respective fuse bodies 41x and 42x facing the bottom wall of the accommodation chamber 50a.
[0026] The housing 50 has a cylindrical connector fitting portion 53 that protrudes from the blocking portion 52 to the outside of the accommodation chamber 50a and communicates its internal space with the accommodation chamber 50a (FIGS. 1, 3, and 4). The connector fitting portion 53 is fitted and connected to a mating connector. Thus, the first main terminal fitting 31 and the second main terminal fitting 33 are inserted into the accommodation chamber 50a from the opening 50b and accommodated in the internal space of the connector fitting portion 53.
[0027] The housing 50 has a first cylindrical portion 54a for drawing the third electric wire 23 out of the accommodating chamber 50a, a second cylindrical portion 54b for drawing the fourth electric wire 24 out of the accommodating chamber 50a, a third cylindrical portion 54c for drawing the fifth electric wire 25 out of the accommodating chamber 50a, and a fourth cylindrical portion 54d for drawing the sixth electric wire 26 out of the accommodating chamber 50a (FIGS. 1 to 4). In the housing 50, the first cylindrical portion 54a and the second cylindrical portion 54b, which are arranged side by side with the same cylindrical axis direction, protrude out of the accommodating chamber 50a from the side wall portion 51, and the third cylindrical portion 54c and the fourth cylindrical portion 54d, which are arranged side by side with the same cylindrical axis direction, protrude out of the accommodating chamber 50a from the side wall portion 51. In the first circuit 10A of the connector 1, the other ends of the third electric wire 23 and the fourth electric wire 24 drawn out from the first cylindrical portion 54a and the second cylindrical portion 54b to the outside of the accommodating chamber 50a are electrically connected to a first external electric device. In the second circuit 10B of the connector 1, the other ends of the fifth electric wire 25 and the sixth electric wire 26 drawn out from the third cylindrical portion 54c and the fourth cylindrical portion 54d to the outside of the accommodating chamber 50a are electrically connected to a second external electric device.
[0028] In this connector 1, the circuit configurations of the first circuit 10A and the second circuit 10B can be changed by changing the connection destinations of the first terminal fitting 32 of the electric wire with first terminal 11, the second terminal fitting 34 of the electric wire with second terminal 12, the third terminal fitting 35 of the electric wire with third terminal 13, the fourth terminal fitting 36 of the electric wire with fourth terminal 14, the fifth terminal fitting 37 of the electric wire with fifth terminal 15, and the sixth terminal fitting 38 of the electric wire with sixth terminal 16.
[0029] 2, the third terminal metal fitting 35 is electrically connected to the other end (second terminal portion 41b) of the first fuse 41 by screw fastening. In this circuit configuration of the first connection mode, the second terminal metal fitting 34 is electrically connected to one end (first terminal portion 42a) of the second fuse 42 by screw fastening, and the fifth terminal metal fitting 37 is electrically connected to the other end (second terminal portion 42b) of the second fuse 42 by screw fastening. In addition, in this circuit configuration of the first connection mode, the fourth terminal metal fitting 36 and the sixth terminal metal fitting 38 are electrically connected to the first terminal metal fitting 32 by screw fastening.
[0030] Specifically, the accommodating chamber 50a accommodates a first screw-locking structure 71 having a first male screw member 71A and a first female screw member 71B that fasten together one end (first terminal portion 41a) of the first fuse 41 and the bus bar 43, and a second screw-locking structure 72 having a second male screw member 72A and a second female screw member 72B that fasten together the other end (second terminal portion 41b) of the first fuse 41 and the third terminal fitting 35 (Figures 3 and 4). The accommodation chamber 50a accommodates a third screw structure 73 having a third male screw member 73A and a third female screw member 73B for fastening together one end (first terminal portion 42a) of the second fuse 42, the bus bar 43, and the second terminal fitting 34, and a fourth screw structure 74 having a fourth male screw member 74A and a fourth female screw member 74B for fastening together the other end (second terminal portion 42b) of the second fuse 42 and the fifth terminal fitting 37 (FIGS. 3 and 4). The accommodation chamber 50a accommodates a fifth screw structure 75 having a fifth male screw member 75A and a fifth female screw member 75B for fastening together the first terminal fitting 32, the fourth terminal fitting 36, and the sixth terminal fitting 38 (FIGS. 3 and 4).
[0031] In the connector 1 of this first connection form, a circuit configuration is constructed in which the electric wire with the first terminal 11, the electric wire with the fourth terminal 14, and the electric wire with the sixth terminal 16 form a negative circuit, and the electric wire with the second terminal 12, the electric wire with the third terminal 13, and the electric wire with the fifth terminal 15 form a positive circuit, forming a first circuit 10A and a second circuit 10B.
[0032] For convenience of explanation, the first connection mode will be used as a reference and changes from the first connection mode to other connection modes (second connection mode, third connection mode, fourth connection mode) will be explained.
[0033] In the accommodating chamber 50a, the first terminal fitting 32 of the electric wire with first terminal 11 can be replaced from the fifth screw structure 75 to the third screw structure 73. In addition, in this accommodating chamber 50a, the second terminal fitting 34 of the electric wire with second terminal 12 can be replaced from the third screw structure 73 to the fifth screw structure 75. In addition, in this accommodating chamber 50a, the third terminal fitting 35 of the electric wire with third terminal 13 can be replaced from the second screw structure 72 to the fifth screw structure 75. In addition, in this accommodating chamber 50a, the fourth terminal fitting 36 of the electric wire with fourth terminal 14 can be replaced from the fifth screw structure 75 to the second screw structure 72. In addition, in this accommodating chamber 50a, the fifth terminal fitting 37 of the electric wire with fifth terminal 15 can be replaced from the fourth screw structure 74 to the fifth screw structure 75. In addition, in the accommodating chamber 50a, the sixth terminal fitting 38 of the sixth terminal-attached electric wire 16 can be attached in a changeable manner from the fifth screw-fastening structure 75 to the fourth screw-fastening structure 74.
[0034] 5 in which the connection destinations of the target terminal fittings are changed from those of the first connection mode, a circuit configuration of a first circuit 10A and a second circuit 10B is constructed in which the electric wire with the first terminal 11, the electric wire with the fourth terminal 14, and the electric wire with the sixth terminal 16 form a positive circuit, and the electric wire with the second terminal 12, the electric wire with the third terminal 13, and the electric wire with the fifth terminal 15 form a negative circuit. In the circuit configuration of the second connection mode, the polarities of the first main terminal fitting 31 and the second main terminal fitting 33 are reversed, the polarities of the third electric wire 23 and the fourth electric wire 24 electrically connected to the first external electric device are reversed, and the polarities of the fifth electric wire 25 and the sixth electric wire 26 electrically connected to the second external electric device are reversed, compared to the circuit configuration of the first connection mode.
[0035] In addition, in the accommodating chamber 50a, the first terminal fitting 32 of the electric wire 11 with the first terminal can be replaced from the fifth screw structure 75 to the third screw structure 73, and the second terminal fitting 34 of the electric wire 12 with the second terminal can be replaced from the third screw structure 73 to the fifth screw structure 75.
[0036] 6 in which the connection destinations of the target terminal fittings are changed from those of the first connection mode, the first circuit 10A and the second circuit 10B are configured such that the electric wire with first terminal 11, the electric wire with third terminal 13, and the electric wire with fifth terminal 15 form a positive circuit, and the electric wire with second terminal 12, the electric wire with fourth terminal 14, and the electric wire with sixth terminal 16 form a negative circuit. In the circuit configuration of the third connection mode, the polarities of the first main terminal fitting 31 and the second main terminal fitting 33 are swapped with respect to the circuit configuration of the first connection mode.
[0037] In the accommodating chamber 50a, the third terminal fitting 35 of the electric wire with third terminal 13 can be replaced from the second screw structure 72 to the fifth screw structure 75. In the accommodating chamber 50a, the fourth terminal fitting 36 of the electric wire with fourth terminal 14 can be replaced from the fifth screw structure 75 to the second screw structure 72. In the accommodating chamber 50a, the fifth terminal fitting 37 of the electric wire with fifth terminal 15 can be replaced from the fourth screw structure 74 to the fifth screw structure 75. In the accommodating chamber 50a, the sixth terminal fitting 38 of the electric wire with sixth terminal 16 can be replaced from the fifth screw structure 75 to the fourth screw structure 74.
[0038] 7 in which the connection destinations of the target terminal fittings are changed from those of the first connection mode, the connector 1 has a circuit configuration of a first circuit 10A and a second circuit 10B in which the electric wire with the first terminal 11, the electric wire with the third terminal 13, and the electric wire with the fifth terminal 15 form a negative circuit, and the electric wire with the second terminal 12, the electric wire with the fourth terminal 14, and the electric wire with the sixth terminal 16 form a positive circuit. In the circuit configuration of the fourth connection mode, the polarities of the third electric wire 23 and the fourth electric wire 24 electrically connected to the first external electric device are swapped, and the polarities of the fifth electric wire 25 and the sixth electric wire 26 electrically connected to the second external electric device are swapped, compared to the circuit configuration of the first connection mode.
[0039] As described above, the connector 1 of this embodiment accommodates the first fuse 41 and the second fuse 42 in one housing 50, and compared to, for example, a case in which a connector for the first circuit and a connector for the second circuit are provided for each fuse, it is possible to reduce costs and improve the spatial efficiency of the connector installation location in the installation object or connection object. Furthermore, the connector 1 of this embodiment not only does this, but also employs a screw fastening structure for connecting the terminal fittings of each of the electric wires with terminals (the electric wire with the first terminal 11, the electric wire with the second terminal 12, the electric wire with the third terminal 13, the electric wire with the fourth terminal 14, the electric wire with the fifth terminal 15, and the electric wire with the sixth terminal 16), so that the circuit configuration of the first circuit 10A and the second circuit 10B can be easily changed by changing the connection destination of each of the terminal fittings. For example, in the above example, by changing the connection destination of the terminal fittings, it is possible to swap the polarity of the first main terminal fitting 31 and the second main terminal fitting 33, swap the polarity of the third electric wire 23 and the fourth electric wire 24 that are electrically connected to the first external electrical device, or swap the polarity of the fifth electric wire 25 and the sixth electric wire 26 that are electrically connected to the second external electrical device.
[0040] In addition, in this connector 1, for example, when either the first circuit 10A or the second circuit 10B is not required, by not assembling either the first fuse 41 or the second fuse 42 related to that unnecessary circuit, it is possible to form only the other circuit of the first circuit 10A or the second circuit 10B.
[0041] Furthermore, in this connector 1, as described above, by limiting the shapes (their size and through-hole pitch) of the first fuse 41 and the second fuse 42 to only one specification, it is possible to use the same component having the same shape and capacity for the first fuse 41 and the second fuse 42, or it is possible to use different components having the same shape but different capacity for the first fuse 41 and the second fuse 42.
[0042] In this way, the connector 1 of this embodiment can easily accommodate changes in circuit specifications. [Explanation of symbols]
