Description

  The present invention relates to a battery terminal block that is attached to a battery and relays power supply from the battery.

  Conventionally, power supply from a battery in a vehicle to a load component in the vehicle is often performed via a battery terminal block that relays power supply from the battery (see, for example, Patent Documents 1 to 3).

  FIG. 6 shows a fuse unit as an example of a conventional battery terminal block. FIG. 7 shows a V51-V51 cross section in FIG.

  The fuse unit 5 is electrically connected to a rod-shaped electrode 62 protruding from the terminal mounting surface 61 in the battery 6. The electrical connection between the fuse unit 5 and the rod-shaped electrode 62 is made via the battery terminal 7 that is directly connected to the rod-shaped electrode 62. The battery terminal 7 is provided with terminal bolts 71 to which the fuse unit 5 is electrically connected and fixed.

  The fuse unit 5 includes a resin housing 51, a battery connection portion 52 connected to the terminal bolt 71 of the battery terminal 7, and four electric wire connection portions 531,. One end of each electric wire reaching each load component is electrically connected and fixed to each electric wire connection portion 531,. 6 and 7, one end of each of the three electric wires 81,..., 83 is electrically connected to three electric wire connection portions 532,. It is fixed together. And the battery connection part 52 and the three electric wire connection parts 531, ... 533 are connected via the two fusing parts 541 and 542 that are fused when a current exceeding a predetermined allowable current flows inside the housing 51. As a result, a fuse function is provided.

  The electric wires 81,..., 83 whose one ends are fixed to the electric wire connecting portions 532,... 534 of the fuse unit 5 are fixed to the fixing points in the vehicle via the cable clamps 91, 92. Here, in the example of FIG. 6, the two electric wires 82, 83 out of the three electric wires 81,..., 83 are gathered together via a cable clamp 92 at a fixed location relatively close to the fuse unit 5.

  Here, for example, the wires 81,..., 83 having one end fixed to the fuse unit 5 may resonate with respect to vibration or the like during traveling of the vehicle. Such resonance amplitude increases as the distance from the fuse unit 5 to the cable clamps 91 and 92 increases. And the larger the amplitude at the time of such resonance, the larger the load F51 that the fuse unit 5 receives from the electric wires 81,... 83, and as a result, the rod-shaped electrode 62 of the battery 6 is connected to the rod-shaped electrode 62 via the fuse unit 5. The applied load increases. In the example of FIGS. 6 and 7, the load load due to the longest electric wire 81 tends to be large. In addition, unlike these examples in FIGS. 6 and 7, there may be a case where a fixed location cannot be set in the first place on the route to the load component. In such a case, the amplitude at the time of resonance is further increased and the load is further increased. In view of the load resistance of the rod-shaped electrode 62 of the battery 6, it is desirable that the load applied to the rod-shaped electrode 62 is as small as possible.

  An object of the present invention is to provide a battery terminal block in which the load applied to the electrode of the battery is suppressed by paying attention to the above problems.

  According to the battery terminal block of the present invention, an intermediate portion from one end of the at least one electric wire on the electric wire connecting portion side to the load component is held by the electric wire holding portion provided in the housing. Thereby, in the electric wire, the length of the free electric wire portion that resonates when vibration is applied from the outside is shortened by the amount from the electric wire connecting portion to the electric wire holding portion of the housing. As a result, the resonance amplitude of the electric wire is suppressed. The load load due to the resonance of the electric wire is received by the electric wire holding portion and applied to the electrode of the battery via the battery terminal block of the present invention. Since the amplitude at the time of resonance in the electric wire is suppressed as described above, the load applied to the electrode of the battery is suppressed. Thus, according to the battery terminal block of the present invention, it is possible to suppress the load applied to the battery electrode.

It is more preferable that a pair of arm portions is configured by providing a slit, and the pair of arm portions are a pair of side wall portions facing each other with end edges facing each other across the slit.

  According to this more preferable battery terminal block, since the outer periphery of the electric wire is clamped and held by substantially the entire inner surface excluding the slit portion of the cylindrical electric wire holding portion, the electric wire can be held more firmly.

  Further, in the battery terminal block of the present invention, a component connection portion that is electrically connected to the battery connection portion and relayed to relay the delivery of the power to the load component is electrically connected and fixed. The relay component includes a resin-made second housing and a relay connection portion that is electrically connected to and fixed to the component connection portion, and the battery is connected to the housing as the wire connection portion. One or more first electric wire connecting portions electrically connected to the terminals are provided, and the second electric wires are electrically connected to the relay connecting portions as the electric wire connecting portions in the second housing of the relay component. When one or more connecting portions are provided, the electric wire holding portion holds the electric wires connected to at least one of the second electric wire connecting portions when the second electric wire connecting portion is one, and the second Electrical wire It is also preferable to retain the electric wire connection portion is connected to at least one of the second wire connecting portion in the case of a plurality.

  According to this suitable battery terminal block, the number of wire connection portions can be increased by providing the first wire connection portion and the second wire connection portion. And at least 1 electric wire connected to the 2nd electric wire connection part in which the distance from the electrode of a battery is long and the load load which acts on this electrode tends to become large is hold | maintained at an electric wire holding part.
