Detailed Description

The principles and spirit of the present invention will be described with reference to a number of exemplary embodiments shown in the drawings. It should be understood that these embodiments are described only to enable those skilled in the art to better understand and to implement the present invention, and are not intended to limit the scope of the present invention in any way.

Referring to fig. 1-2, an embodiment of the present invention provides an apparatus for rapidly changing functions of relays of different items based on an NI HIL rack, including a tool box 1, where the tool box 1 includes a plurality of relays 2 therein, and the relays 2 are used for each item of a BMS test. Each relay 2 is connected with a controlled lead 3, a male head 6 is arranged on the controlled lead 3 and led out to the outside of the tool box 1, and the two ends of each relay are NI HIL rack simulation high-voltage structure leads 5. Still include the relay control pin of a plurality of BMS in the frock box 1, the relay control pin of every BMS uses female head 4.

In this embodiment, the public head 6 that relay 2 controlled lead wire 3 adopted is the public head of banana head, and correspondingly, female head 4 that the relay control pin of BMS used is the female head of banana head. Through the mode that the banana head is drawn forth relay control pin, can reduce the change to whole NI HIL rack wiring structure, have certain effect to keeping NI HIL rack wholeness, security, stability. Meanwhile, the banana head has the characteristics of quick, real-time and durable plugging. When BMS test items changed, can be quick extract the public head 6 that corresponds the controlled lead wire of original relay to the public head 6 of hanging outside the frock box that will satisfy the condition of having drawn forth inserts the banana head female head of frock box 1 panel, realizes test items's fast switch-over.

For example, when the male head of the 1 banana head of BMS relay control pin in the item 1 is the control pin of the heating relay, and the 2 banana heads of the relay control pin are the main positive relay control pin, the male head of the 1 banana head of the pin is inserted into the high-voltage structure of the rack and is consistent with the control pin of the 1 relay used as the heating relay, and the banana head of the 2 banana heads of the pin is inserted into the high-voltage structure of the rack and is consistent with the control pin of the 2 relay used as the main positive relay. After switching items, when the relay 1 in the high-voltage structure on the rack is used as a main positive relay, the BMS relay control pin 2 is only required to be inserted into the banana head of the control pin of the relay 1 again.

In this embodiment, the lead wire adopted by the male head 6 is the spring lead wire 7, which can be freely stretched to change the length, so as to more flexibly adjust the plugging position of the male head 6. And the spring lead 7 is provided with a spring plastic pipe, so that the protection effect is achieved, and when the tool box is suspended, the pin is prevented from being touched by mistake.

The tooling box 1 further comprises a line concentration structure 8, and the line concentration structure 8 is used for regulating all lead wires corresponding to the relay control pins. In this embodiment, the line concentration structure 8 is an opening formed in the tool box 1, and the opening is directly formed in the tool box 1, so that a line concentration part does not need to be separately arranged, and the integrity of the whole device is improved. The opening is preferably arranged on the side edge of the tooling box 1, so that the lead cannot shield the shell panel of the tooling box 1, and the male head 6 is also convenient to suspend.

Be equipped with the female first jack 9 that corresponds with the female head of banana head on the shell panel of industrial box 1, make things convenient for the tester to observe.

In this scheme, with public first one end of spring banana head and relay and receive the contact of control pin (female head), control relay work. When changing the relay function, only need with banana head male plug insert the banana head female head connect can to the relay function of different projects under the same BMS platform of quick change.

The present invention has been described in detail with reference to specific embodiments, which are provided to assist in understanding the core concepts of the present invention. It should be understood that any obvious modifications, equivalents and other improvements made by those skilled in the art without departing from the spirit of the present invention are intended to be included within the scope of the present invention.
