Description
Technical field
What is involved is a kind of upper cover plates of battery for a kind of lead-acid accumulator cover board of the utility model.
Background technique
Cover board is provided with above lead-acid accumulator, existing cover board is direct one piece of cover board, is provided with above just
Cathode and liquid injection hole in use, are especially filled due to being perfused with a large amount of acidic electrolysis bath inside lead-acid accumulator
In electric process, acidic liquid is readily volatilized and the loss from liquid injection port, be easy on lead-acid accumulator positive and negative electrode and
The conducting wire for connecting positive and negative electrode generates corrosion, influences the service life of lead-acid accumulator, so to design a kind of new cover board
Overcome drawbacks described above, meets actual use demand.
Utility model content
The utility model can be effectively prevent on existing cover board in view of this, provide a kind of lead-acid accumulator cover board
Positive and negative electrode and relevant conducting wire prematurely generate corrosion, have preferable using effect.
A kind of lead-acid accumulator of the utility model has the cover board of rectangle with cover board, and the both ends on surface are set respectively on the cover board
It is equipped with anode and cathode, liquid injection hole is provided between a positive electrode and a negative electrode, is provided with port lid on liquid injection hole, prevents electrolyte from spilling
Out；
It is provided with cylindrical boss on the anode and cathode, is provided with threaded hole, screw thread at the center of boss
Lower section inside hole is provided with threaded rod, and threaded rod protrudes into the lower section of cover board and is connected with corresponding electrode plate, and electrode plate is used for
Infiltration is in the electrolytic solution；Spiral is connected with electrode bolts above threaded hole, and electrode bolts are contacted with threaded rod, in electrode bolts
It is cased with connection strap, connection strap is the metal strip that both ends are each provided with threaded hole, and the other end of connection strap can be connected to another
On the opposite electrode of lead-acid accumulator.
The connection strap removes at threaded hole, is enclosed with insulating layer.
The insulating layer is electro-insulating rubber.
Rubber ring is additionally provided with above or below connection strap, to play the role of sealing and preload.
The head of the electrode bolts is arranged with insulation headgear, and insulation headgear is phenoplasts.
It is provided in the liquid injection hole and flows to downward check valve, come for further preventing electrolyte to sprinkle to shed.
The utility model structure is simple, is skillfully constructed, is easy to use, when in use by positive and negative anodes on multiple lead-acid accumulators
Electrode bolts unscrew, connection strap is connect respectively between the anode and cathode of adjacent lead-acid accumulator, formed series circuit,
Connect electrical equipment and switch, the utility model by the head of connection strap and electrode bolts be provided with insulating layer,
Insulate headgear, the phenomenon that not only preventing accidental shock, and due to strict package, effectively prevent moisture in air, volatilization
Corrosion of the acidic materials to the metal parts of electrode and connection strap, it is effectively anti-and due to being provided with check valve in liquid injection hole
Acidic electrolysis bath volatilization is stopped, and thereby has reduced the number of supplement electrolyte, reduced the corrosion of electrode, there is good make
With and promotion effect.
Detailed description of the invention
Below in conjunction with attached drawing, the utility model is described in further detail:
Fig. 1 is a kind of structural schematic diagram of lead-acid accumulator cover board of the utility model;
Fig. 2 is that a kind of plan structure of the lead-acid accumulator cover board of the utility model when two pieces of lead-acid accumulators connect is shown
It is intended to.
Specific embodiment
Referring to attached drawing 1-2, a kind of lead-acid accumulator has the cover board 9 of rectangle with cover board, at the both ends point of 9 upper surface of cover board

Only electrolyte spills；
It is provided with cylindrical boss on the anode 1 and cathode 2, is provided with threaded hole, spiral shell at the center of boss
Lower section inside pit is provided with threaded rod, and threaded rod protrudes into the lower section of cover board and is connected with corresponding electrode plate, and electrode plate is used
In the electrolytic solution in infiltration；Spiral is connected with electrode bolts 7 above threaded hole, and electrode bolts 7 are contacted with threaded rod, in electrode spiral shell
Connection strap 5 is cased on bolt 7, connection strap 5 is the metal strip that both ends are each provided with threaded hole, and the other end of connection strap 5 can connect
On the opposite electrode of another lead-acid accumulator.
The connection strap 5 removes at threaded hole, is enclosed with insulating layer.
The insulating layer is electro-insulating rubber.
Rubber ring 8 is additionally provided with above or below connection strap 5, to play the role of sealing and preload.
The head of the electrode bolts is arranged with insulation headgear, and insulation headgear is phenoplasts.
It is provided in the liquid injection hole 3 and flows to downward check valve 6, come for further preventing electrolyte to sprinkle to shed.
