Raw safety in production failure.
Utility model content
The utility model is intended to provide a kind of electrode for cell connection sheet, to solve wiring boss on present cell connector
Easily loosening, the low problem of joint efficiency are connect with voltage acquisition line.
One of this programme electrode for cell connection sheet, including connection substrate and wiring boss, the connection substrate with
Wiring boss is made of conductive metal, and connects substrate and wiring boss and be integrally formed, and the wiring boss is to connection substrate
It is external stretch out, the linker on piece is equipped with several uniform circular holes of arrangement, is respectively connected with two electricity in each circular hole
Core contact pin, the wiring boss is interior to be equipped with semicircular arc-shaped groove, and one end of the groove extends to the edge of wiring boss, makes
Wiring boss edge forms the notch with groove perforation.
The working principle and beneficial effect of the utility model:
One end peeling of voltage acquisition line when in use, need to only be reconnected contact pin by the electrode connecting piece of the utility model
Afterwards, then by notch by contact pin it is put into groove, the two sides of pliers clamping recess is then used, thus by voltage acquisition line and connection
Piece closely connects.Using this practical electrode connecting piece, when being attached with voltage acquisition line, efficiency is very high, only needs
The contact pin for connecting voltage acquisition line is put into the two sides that groove borrows pliers clamping recess again, and compactness is very good,
It is not in conductive bad phenomenon.During entire assembly and connection, no electricity and high temperature, therefore also more secure and reliable.
Preferably, the other end of the groove is connected with more conductive fill lines.Due to being clamped to groove two sides
During, if active force is too small, it is possible that the case where holding inadequate consolidation influences so that occurring gap in groove
Electric conductivity.The effect of conductive fill line is, after contact pin is put into groove, conductive fill line is made to be evenly distributed on contact pin
Around, then clamp again, dynamics timely in this way is slightly smaller, also can because of a part of filling effect of the electric filling line around contact pin and
Connect even closer, electric conductivity is more preferable.
Preferably, the conductive fill line is copper wire, and the diameter of the copper wire is 0.1~0.5mm.The good conductivity of copper,
And plasticity is strong, and brass wire diameter is limited between 0.1~0.5mm, not only can guarantee that the conduction of copper wire is reliable, but also can guarantee filling
Effect it is more preferable.
Preferably, the wiring boss is equipped with the metal stator of two pieces of mirror symmetries, between two pieces of fixinig plates
Gap is formed, the gap is located at the end of groove one end, and gap is opposite with wiring boss.By the contact pin of voltage acquisition line
It being put into groove and after clamping, contact pin is loosened and is skidded off in order to prevent, in the extending direction of groove, two pieces of fixinig plates are set again,
Since there is metal stator ductility contact pin can be allowed to fix more firm by inwardly clamping two pieces of fixinig plates.
Preferably, the fixinig plate is copper sheet, and the inner wall of the copper sheet is equipped with several protrusions, and protrusion can increase friction
Power, and have the effect of increasing fastening.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of electrode for cell connection sheet of the utility model；
Fig. 2 is the structural schematic diagram of wiring boss in the utility model；
Fig. 3 is the structural schematic diagram of the utility model further groove.
Specific embodiment
Below by the further details of explanation of specific embodiment:
Appended drawing reference: connection substrate 1, wiring boss 2, circular hole 3, battery core contact pin 4, groove 5, conductive fill line 6, fixinig plate
7, protrusion 8.
As shown in Figure 1, Figure 2 and Figure 3, the utility model provides a kind of electrode for cell connection sheet, especially in
Lithium ion cylinder battery PACK, i.e. lithium battery combination.Electrode connecting piece includes connection substrate 1 and wiring boss 2, connects substrate
1 and wiring boss 2 be that conductive metallic material integrated molding is made, the preferred copper of conductive metal, but it is conductive to can also be other
Metal.Wiring boss 2 is stretched out to the outside of connection substrate 1, and for connecting voltage acquisition line, connection substrate 1 is equipped with two rows of equal
The circular hole 3 of even arrangement is connected with two battery core contact pin 4, battery core contact pin 4 and single battery cell in circular hole 3 by welding, and is flowed to
It connects on substrate 1, to form the series and parallel structure of lithium battery.One of semicircular arc-shaped groove 5 is provided in wiring boss 2,
For the contact pin for connecting voltage acquisition line to be put into wherein, one end of groove 5 stretches out wiring boss 2 and forms notch, is convenient in this way
The contact pin of voltage acquisition line can be horizontally inserted into groove 5.The other end of groove 5 is connected with more conductive fill lines 6, conductive fill
Line 6 is copper wire, and the diameter of copper wire is 0.1~0.5mm, and the present embodiment selects the copper wire of 0.3mm as conductive fill line 6.It is connecing
It is additionally provided with the metal stator 7 of two pieces of mirror symmetries on line boss 2, forms gap between two pieces of fixinig plates 7, is located at groove 5
The end of one end, and gap and wiring boss 2 are opposite, the contact pin convenient for voltage acquisition line can be inserted into groove 5 simultaneously and fix
In gap between piece 7, fixinig plate 7 is allowed to play the role of the contact pin that is fixedly clamped.Fixinig plate 7 selects copper sheet optimal, also can in this way
Certain electric action is played, contact pin, since fixinig plate 7 is copper sheet, has and prolongs in the gap location being put between two fixinig plates 7
Malleability can play the role of clamping contact pin, there are also several convex on the inner wall of copper sheet by inwardly clamping two fixinig plates 7
