DETAILED DESCRIPTION

[0022] In order to achieve the above-mentioned purpose and effect, the technical means and structures adopted by the present invention are described in detail with reference to the accompanying drawings for the features and functions of the preferred embodiments of the present invention.

[0023] like Figure 1-5 As shown, the present invention provides a quick connection device for a battery pack, comprising: A bottom plate 1, which is arranged on a battery rack of a battery pack, and a plurality of insulating columns 3 are arranged on the top of the bottom plate 1; A copper bar 2, which is arranged on an insulating column 3, and a plurality of wiring nuts 4 are evenly arranged at both ends of the copper bar 2; A quick connector 5, which is arranged on the copper bus 2 and is electrically connected to the copper bus 2; Side plates 6, which are arranged on the bottom plate 1 and located on both sides of the copper busbar 2 to shield both sides of the copper busbar; The front plate 7 is arranged on the bottom plate 1 and is located in front of the copper bus 2. The front plate 7 is close to the wiring nut 4. The front plate 7 is provided with a cable port for the wiring cables to enter and exit. The rear plate 8 is arranged on the bottom plate 1 and is located behind the copper bus 2. The rear plate 8 is provided with a power port for the battery cable to enter and exit; The top plate 9 is located above the copper bus 2 and is slidably connected to the side plate 6 .

[0024] The bottom plate 1 , the side plates 6 , the front plate 7 , the rear plate 8 and the top plate 9 enclose the copper busbar 2 in a working space to prevent workers from directly contacting the copper busbar 2 with their hands or objects.

[0025] In actual use, the staff needs to manually pull open the top plate 9 to expose the copper bar 2, and fix the discharger cable to the copper bar 2 through the quick connector 5. The battery cable is connected to the wiring nut 4 at one end, and the protection cable is connected to the wiring nut 4 at the other end. The protection cable extends into the working space through the power port on the rear plate 8, and the battery cable extends into the working space through the cable port on the front plate 7. After the discharger is connected, turn on the switch on the battery to supply power and discharge.

[0026] Specifically, the bottom plate 1 is made of insulating bakelite.

[0027] Specifically, the copper busbar 2 is also provided with bakelite, and the quick connector 5 is provided on the bakelite.

[0028] Specifically, four wiring nuts 4 are provided at each end, each of which is threadedly connected to the copper bus 2, and the connecting screw hole is an M8 screw hole.

[0029] Specifically, one end of the protection cable is connected to the wiring nut 4, and the other end is connected to the DC screen in the protection room, and is connected to the DC bus through the fuse and switch in the screen. There are two protection cables, and the extra wiring nut 4 is used as a spare or to replace the quick connector 5 to connect to the discharger.

[0030] In another embodiment, a slideway is provided at the upper end of the side plate 6, and sliders adapted to the slideway are provided at both ends of the top plate 9. The sliders extend into the slideway and are slidably connected to the slideway. The position of the top plate 9 is changed by sliding the sliders to realize the opening and closing of the working space. An electromagnet is provided at one end of the slideway, and the electromagnet is electrically connected to the battery. The slider is made of metal material that can be adsorbed by the electromagnet.

[0031] When the battery is in the starting state, the electromagnet is energized, and the slider is attracted to one end of the slide by the electromagnet, so that the top plate 9 closes the working space. At this time, the staff cannot directly open the top plate 9 to connect and remove wires. The staff needs to turn off the battery so that the electromagnet no longer attracts the slider before opening the top plate 9 to work. This prevents the staff from operating or foreign objects from entering the working space when the battery is running, thereby ensuring the safety of the device when in use.

[0032] Specifically, the device can be provided with multiple wiring nuts 4 on multiple devices which can be respectively connected to the positive and negative poles of the battery, so that the copper busbar carries positive or negative electricity. At this time, the positive and negative poles of the electromagnet on the device can be connected to the corresponding copper busbar 2, thereby reducing the wiring length of the electromagnet and improving safety.

[0033] In another embodiment, a sliding cover 10 is provided at one end of the front plate 7 close to the copper bus 2, and the sliding cover 10 is used to control the opening and closing of the cable port. Thus, the sliding cover 10 is used to close the cable port when no wiring is connected, so as to prevent foreign matter from entering the working space through the cable port.

[0034] Specifically, a power cover for controlling the opening and closing of the power port is provided on the rear plate 8 .

[0035] In another embodiment, the sliding cover 10 is slidably connected to the front plate 7, and the sliding cover 10 can slide vertically on the front plate 7. A sliding sleeve is provided on the top of the sliding cover 10, and a fixing column 11 slidably connected to the sliding sleeve is provided inside the sliding sleeve. A sliding groove 16 matching the fixing column 11 is provided on the front plate 7. The staff can slide one end of the fixing column 11 into the sliding groove 16 to achieve temporary fixation of the sliding cover 10.

[0036] Specifically, the sliding sleeve includes a first sliding sleeve 12 and a second sliding sleeve 13, and there is a certain interval between the first sliding sleeve 12 and the second sliding sleeve 13. The fixing column 11 is provided with a handle, and the handle is located between the first sliding sleeve 12 and the second sliding sleeve 13. Thus, the handle facilitates the operation of the fixing column 11 by the staff, and prevents the fixing column 11 from sliding off the first sliding sleeve 12 and the second sliding sleeve 13.

[0037] Specifically, a cross-section plate 14 is provided below the cable opening, and the cross-section plate 14 is used to support the sliding cover 10. Thus, when the sliding cover 10 closes the cable opening, the sliding cover 10 is supported by the cross-section plate 14, thereby improving the service life of the sliding cover.

[0038] Preferably, a tension spring is provided between the cross-section plate 14 and the sliding cover 10 to ensure that the sliding cover 10 is subjected to a force to move toward the cross-section plate 14 .

[0039] In another embodiment, a plurality of support plates 15 are vertically arranged below the sliding cover 10, the support plates 15 are located on both sides of the cable opening and are slidably connected to the front plate 7, so that the support plates 15 can slide horizontally on the front plate 7. Therefore, when cables are connected, the operator can slide the support plates 15 corresponding to the cable positions to the bottom of the sliding cover 10, and the other support plates 15 to both sides, so that the sliding cover 10 is supported by the support plates 15, so that the size of the cable opening is adapted to the cable.

[0040] In another embodiment, a temperature measuring device and an alarm unit are further included, wherein the temperature measuring device is disposed on the copper busbar 2, and the alarm unit is electrically connected or signal-connected to the temperature measuring device. The temperature of the copper busbar 2 is detected by the temperature measuring device, and the temperature measuring device sends the detection result to the alarm unit. When the temperature is abnormal, the alarm unit will sound an alarm to remind the staff.

[0041] Specifically, the temperature measuring device is a temperature measuring cable, and the temperature measuring cable is arranged on the back side of the copper bus 2 and close to the quick connector 5.

[0042] Specifically, the alarm unit includes a temperature alarm, an auxiliary power supply, a protective circuit breaker and a flame-retardant plastic distribution box. The temperature alarm, the auxiliary power supply and the protective circuit breaker are arranged in the flame-retardant plastic distribution box. The temperature alarm is electrically connected or signal-connected to the temperature measuring device, the auxiliary power supply is electrically connected to the temperature alarm, and the protective circuit breaker is used for fault isolation during short circuit. The staff can set the alarm temperature on the temperature alarm. When the temperature detected by the temperature measuring device exceeds the preset alarm temperature, the temperature alarm sounds an alarm to remind the staff that there may be poor contact at the wiring and timely intervention is required. When a short circuit occurs in the temperature alarm or the auxiliary power supply, the protective circuit breaker will trip to isolate the fault point, protect the battery pack, and improve safety.

[0043] Specifically, the positive and negative electrodes of the temperature alarm can be respectively connected to the corresponding copper busbars 2 connected to the positive and negative electrodes of the battery, and the copper busbars 2 are used to supply power to the temperature alarm.

[0044] Specifically, one or more heat dissipation holes are provided on the flame-retardant plastic distribution box to avoid heat accumulation in the box.

[0045] Specifically, the four sides of the flame-retardant plastic distribution box are equipped with knock-out cable entry holes to facilitate staff to choose the appropriate direction for cable entry.
