Description
Technical field
The utility model relates to lead storage battery technical fields, more particularly to a kind of accumulator terminal.
Background technique
Lead storage battery terminal part, since terminal material is different with battery cover material, the coefficient of expansion is different, by environment
Temperature influences, and junction is also easy to produce micro gap, and due to acid solution capillary phenomenon, cell cover is gone up in seeping from gap slowly, produces
It is raw to climb acid or leakage, it causes battery terminal and binding post to corrode, pollutes ambient enviroment, corrode vehicle body when serious, it is hidden to generate safety
Suffer from.On the other hand, newel post's (connecting column) and connection sheet (substrate) can generate displacement or loosening when locking screw, and poor contact is caused to produce
Raw battery quality problem, so that return of goods rate be caused to rise.
For example, the Chinese utility model patent that Authorization Notice No. is CN206758547U discloses a kind of accumulator terminal,
It is made of the copper core of copper sheet and column structure, it is in first that step is successively decreased that the lateral wall of copper core is successively arranged outer diameter from top to bottom
Step, second step and third step, and the upper surface center setting of copper core is perpendicular to the threaded hole of upper surface；Copper sheet
One end is equipped with welding hole with the major diameter fit of third step, and the upper surface of copper sheet is vertical with the outer diameter face of second step is affixed simultaneously
By being welded and fixed, the other end of copper sheet is equipped with horn-like pole column hole, and the inclined surface bottom end of pole column hole is equipped with welds with battery electrode column
Connect fixed extension boss.
Authorization Notice No., which discloses one kind for the Chinese utility model patent of CN204905346U, to be prevented twisting lead-acid accumulator
Terminal, including substrate and connecting column, the connecting column include the base portion mutually welded with substrate and the head for connecting with external connection
Portion, the diameter on head are greater than the diameter of base portion, and the substrate is equipped with the pilot hole matched with the base portion, the pilot hole
Periphery have several notches.
Currently, changing material by optimization terminal structure, increases the modes such as auxiliary material, do not solve this thoroughly and ask
Topic.As country reinforces environmental requirement, it is desirable that battery effect on environment is smaller, and the service life is longer, it is desirable that terminal sealing effect
Fruit is more preferable, while can facilitate production, promotes battery production efficiency, reduces the overall cost of production and improves product quality.
Utility model content
The utility model is directed to the deficiencies in the prior art, provides a kind of accumulator terminal, can effectively prevent
It rotates in use between substrate and connecting column, to influence battery quality.
A kind of accumulator terminal, including substrate and connecting column, the connecting column include the base portion mutually welded with substrate and
For connecting the head of external connection, the diameter on head is greater than the diameter of base portion, and the substrate is equipped with the cooperated with the base portion
One pilot hole, the periphery of first pilot hole are equipped with positioning protrusion, correspondingly, the outer peripheral surface of the base portion be equipped with it is described fixed
The positioning groove of position male cooperation.
The length that the positioning protrusion protrudes into the first pilot hole is 0.5~1.1mm, and width is 1.4~1.9mm, thickness and institute
The thickness for stating substrate is identical.
The head outer peripheral surface is evenly distributed with multiple vertical straight knurling.Pass through the head outer peripheral surface increasing in connecting column
Add vertical straight knurling, the bond strength between terminal and sealant can be increased, reduces connecting column in use and send out
The raw possibility loosened, while the case where climbing sour leakage generation can also be reduced.The straight knurling is located at the lower part on the head
1/3~1/2.The quantity of the straight knurling is 5~20.The width of the straight knurling is 0.35~1.1mm.
The substrate has the second pilot hole connecting with battery post, first pilot hole and the second pilot hole point
Set on the both ends of substrate, the substrate is equipped between the first pilot hole and the second pilot hole to be passed through in assembling for sealant
Through-hole.The setting of the through-hole penetrates on the downside of substrate convenient for sealant when assembling, avoids due among terminal and cell through lid
The terminal for lacking glue and generating climbs sour problem.
The utility model accumulator terminal is matched by being arranged between the first pilot hole of substrate and the base portion of connecting column
The positioning protrusion and positioning groove of conjunction, to make after welding between substrate and connecting column, connecting column is not easy in use
Counter substrate is subjected to displacement or loosens, and reduces the battery quality problem that poor contact generates.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model accumulator terminal.
Fig. 2 is the structural schematic diagram of connecting column.
Fig. 3 is the structural schematic diagram of substrate.
Specific embodiment
As shown in Figures 1 to 3, a kind of accumulator terminal, including substrate 1 and connecting column 2.Connecting column 2 includes welding with 1 phase of substrate
The base portion 21 connect and the head 22 for connecting external connection, the diameter on head 22 are greater than the diameter of base portion 21, substrate 1 be equipped with
The periphery of the first pilot hole 11 that base portion 21 cooperates, the first pilot hole 11 is equipped with positioning protrusion 12, correspondingly, the periphery of base portion 21
Face is equipped with the positioning groove 23 cooperated with positioning protrusion 12.Pass through the base portion 21 of the first pilot hole 11 and connecting column 2 in substrate 1
Between the positioning protrusion 12 and positioning groove 23 matched is set, thus make between substrate 1 and connecting column 2 weld after, using
