Technical Field
The utility model belongs to the technical field of series battery group test technique and specifically relates to a series battery group pencil keysets.
Background
Series batteries are produced in order to obtain higher voltages from the batteries. The series battery pack is formed by connecting a plurality of batteries in series in practical application, and a battery pole is connected to the protection plate through a wire harness to form a controllable battery pack. And the series battery pack test needs to be connected with an equalizer to perform equalization maintenance on the battery pack. When the balancing instrument is used for carrying out balanced maintenance on the battery pack, the protection plate is detached, and the wiring harness connected with the battery pole is connected to the balancing instrument through the wiring harness adapter plate; and after the balance maintenance is finished, the protection plate is connected again.
At present, the protective plate interface of the battery pack produced by the main battery pack supplier is a single-row straight needle with the needle pitch of 2.0mm, and the wire harness interface connected with the protective plate interface is a single-row plug with the hole pitch of 2.0 mm. The single row plug rarely exceeds 16P, but the number of cells in a series battery pack often exceeds 16, and it is conventional practice to divide the series battery pack signal lines into two groups, each group of signal lines being connected to a single row plug. The problem of this solution is that two single row plugs with a hole pitch of 2.0mm are plugged together at a short distance, and the ends of the two plugs interfere with each other, so that the two plugs cannot be connected.

However, the problem of staggered insertion is easily caused due to the small distance (usually 2mm) between the pins of the single-row straight pins, which may cause the short circuit of the series battery pack to burn out, or may cause the wire harness to burn out, the wire harness adapter plate to burn out, and the balancing instrument to burn out, or even cause more danger.

The embodiments of the present invention have been presented for purposes of illustration and description, and are not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiment was chosen and described in order to best explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.
Example 1
A series battery harness patch panel 200, as shown in fig. 2, includes a first harness connection terminal 201, a second harness connection terminal 202 and a third harness connection terminal 203, wherein a distance exists between the second harness connection terminal and the third harness connection terminal. In this embodiment, a is 22, b is 13, and c is 9.
The first wiring harness connecting end is provided with 22 conductive contacts which are sequentially defined as 1-1, 1-2 and 1-3 … … 1-22;
the second wiring harness connecting end is provided with 13 conductive contacts which are sequentially defined as 2-1, 2-2 and 2-3 … … 2-13;
the third wiring harness connecting end is provided with 9 conductive contacts which are sequentially defined as 3-1, 3-2 and 3-3 … … 3-9;
the conductive contacts 1-1, 1-2 and 1-3 … … 1-13 are connected to 2-1, 2-2 and 2-3 … … 2-13 through conductors in sequence;
the conductive contacts 1-14, 1-15 … … 1-22, in turn, are connected to 3-1, 3-2, 3-3 … … 3-9 by conductors.
For matching with the battery pack end interface, the second harness connection end 202 and the third harness connection end 203 both adopt single-row straight needles with a pitch of 2.0 mm. The first harness connection end 201 can be freely selected, in this embodiment, the plug-in type PCB connection terminal 2EDGK 5.08mm (usually green) is selected, and the straight pin socket and the bent pin socket are all available, but a conductive contacts of the first harness connection end are required to be arranged in a row, and the distance between the adjacent conductive contacts is equal and is matched with the needle pitch of the socket. Of course, in terms of specification selection of the connection terminal, the second harness connection terminal 202 and the third harness connection terminal 203 may also select a single row of straight needles with a needle pitch of 2.54mm, or the single row of straight needles with the needle pitches of 2.0mm and 2.54mm may be simultaneously disposed on the harness patch panel; the first harness connection end 201 may also be selected from a straight pin socket or a bent pin socket with a 3.96mm pitch.
In actual use, as shown in fig. 3, the interface 101 of the equalizer is connected to the first harness connection end 201 through the first harness connection member 301, and further, the equalizer signal is connected to the first harness connection end 201 and the second harness connection end 202; the cell signal of the series battery pack 107 is connected to the second harness connection terminal 202/the third harness connection terminal 203 through the second harness connection member 302/the third harness connection member 303, respectively. Because the first wiring harness connecting end is connected with the second wiring harness connecting end and the third wiring harness connecting end through the conductive contacts and the conductors, the cell signal is equivalently connected with the signal of the equalizer, and the switching function is realized.
And a certain distance exists between the second wire harness connecting end and the third wire harness connecting end, so that a space is reserved for the end head of the needle seat, and the structural interference is avoided. Therefore, the "certain distance" is limited to ensure that the sockets connected to the second and third harness connection terminals 202 and 203 can be freely inserted and removed without structural interference.
In order to save space and keep the appearance neat and beautiful, the second harness connecting end 202 and the third harness connecting end 203 are arranged side by side and opposite to the first harness connecting end 201, as shown in fig. 2.
The wiring harness adapter plate is a circuit board, the conductive contacts are bonding pads distributed on the circuit, the single-row straight needles are correspondingly welded with the bonding pads on the circuit board, and conductors connected with the conductive contacts on the two sides are flying wires or wires printed in the circuit board, preferably the wires printed in the circuit board.
In the wiring operation, the series battery pack is connected to the second and third harness connection terminals 202 and 203 through the second and third harness connection members 302 and 303, respectively. Even if the number of conductive contacts of the second harness connection terminal 202 and the third harness connection terminal 203 changes, as long as the second harness connection member 302 and the third harness connection member 303 are inserted from the adjacent terminals and then expanded outward, referring to the corresponding relationship shown in fig. 3, the second harness connection terminal 202 is fully inserted from the top and the two pins are not fully inserted from the bottom, and when the first harness connection member 301 is connected to the first harness connection terminal 201, the third pin is inserted from the bottom of the first harness connection terminal 201. The problem of malposition plugging can not occur according to the standard connection.
Example 2
In order to ensure that the connection of the wire harness is correct and visually display whether the connection of the wire harness is correct, in this embodiment, on the basis of embodiment 1, a light-emitting indication unit and a light-emitting indication circuit 401 in which a resistor (1000 Ω) is connected in series are disposed between two adjacent conductive contacts of the first harness connection end 201, and the light-emitting indication unit may employ two light-emitting diodes connected end to end, as shown in fig. 4.
Meanwhile, every other light-emitting indicating circuit is connected with a bias resistor 402(200 omega) between two adjacent conductive contacts, and the bias resistor is used for biasing the voltage between the unconnected contact and the adjacent contact when the wire is broken so as to extinguish the light-emitting diode which is connected with the forward direction and accordingly clearly indicate the wire breaking problem. The working principle is as follows: when a voltage difference exists between two signals connected with the same bias unit, current flows through the bias unit, and if one wire of the wiring harness is disconnected, the voltage of the disconnected wire is biased to one side, so that the light-emitting diode with low voltage is not lighted.
If the polarity of the battery is connected reversely, the light emitting diode connected reversely is lightened, and the light emitting diode connected in the forward direction is not lightened, so that the reverse connection problem is clearly indicated. Because the red and yellow LED lamps have lower on-voltage, LED lamps of these two colors can be used for a wider range of battery voltages. The higher the power of the biasing unit resistor and the current-limiting resistor is, the higher the withstand voltage is, and the line sequence is not easy to burn under the condition of high voltage.
After the wiring is definitely not in a problem, the balancing instrument is connected to the wiring harness adapter plate 200, and the safe use of the balancing instrument is ensured.
It is obvious that the described embodiments are only some of the embodiments of the present invention, and not all of them. Based on the embodiments in the present disclosure, all other embodiments obtained by a person of ordinary skill in the art and related fields without creative efforts shall fall within the protection scope of the present disclosure.
