Description
Technical field
The present invention relates to field of electrical components, more particularly to a kind of eccentric structure voltage probe.
Background technology
The interior voltage probe of current line in the industry is essentially all concentric pin.With the development of battery, have among battery pole ear
One recessed circle or through hole, its common diameter is 7mm, 8mm and 10mm, when carrying out probe voltage test, as shown in Figure 1,
If probe tip 100 typically, according to concentric pin design method, can cause product straight in recessed circle or the outer side test of through hole
Footpath size increase, it at the same time can cause the enlarged diameter of product plastics external piece, it will influence the final installation of product, make
With, while can also increase production cost.
The content of the invention
The present invention is to solve the above problems, provide a kind of eccentric structure voltage probe, and using off-center probe structure, reduction is visited
The profile main body of pin, it both can guarantee that end of probe voltage was directed to the test request of battery pole ear, and can meets product actual installation
Physical dimension requirement.
To reach above-mentioned purpose, the technical solution adopted by the present invention is：A kind of eccentric structure voltage probe, including main shaft,
Flexible member, insulation external piece, conductive component and probe bodies, main shaft inner hollow, its outside are followed successively by main shaft from front to back
Probe, flexible member, insulation external piece and conductive component；Probe bodies number is 2, and the probe of its front end passes through inside partially
The fixing groove of the heart is connected with probe rod in rear end, and two probe rods are spacing by the insulated slide part of front end, the insulation at middle part
Part and the insulating part of rear end are separate to be arranged on the inside of main shaft；Probe rod front end is provided with spacing protrusion, and spacing protrusion is exhausted
Edge sliding part inside front ends prop up insulated slide part, and the probe rod between insulated slide part and insulation locating part, which is provided with, resets bullet
Spring；Probe rod rear end, which is higher by insulating part, is provided with neck, and snap ring is connected with neck.
Further, conductive component include by the rear end of front end be connected in turn the first locking nut on main shaft, pad,
Waveform elastic part, conductive braided fabric line and the second locking nut.
Further, the insulate rear end of external piece is provided with fixed leading end, and its rear end end is external connection end, and external connection end passes through
Wire is connected with conductive braided fabric line.
Further, snap ring limitation probe front end exceeds main shaft probe.
Further, syringe needle and probe rod can also be integrally formed eccentric structure.
Operation principle and its advantage of the present invention are as follows：
External connection end is connected with current circuit, is charged by main shaft, and especially by main shaft probe for battery.
Probe is fixed on panel by insulation external piece, probe rod rear end connection voltage tester circuit, is examined by probe
Survey the voltage of battery.
Specifically, in the presence of contact, probe end motion backward, now probe rod promote insulated slide part to
End motion afterwards, then, main shaft probe contact battery, battery charging.
After battery charges electricity, main shaft probe leaves battery, because under normality, probe is exposed on the outside of main shaft, works as master
Axle probe leaves battery, and back-moving spring promotes the end motion forward of insulated slide part, so as to promote probe rod to think nose motion, when
When snap ring props up insulating part, probe contact battery, and main shaft probe does not contact, and carries out voltage detecting.
It is worth noting that, when probe and probe rod are designed using split, spacing protrusion can effectively prevent probe
Head comes off because of the effect of back-moving spring.
In summary, the invention has the advantages that：
Originally concentric voltage pin is changed to eccentric structure by the present invention, can be reduced the profile main body of probe, both be can guarantee that probe
Head voltage is directed to the test request of battery pole ear, and and can meets the physical dimension requirement of product actual installation
The also favourable saving product of the present invention uses space, increases utilization rate of equipment and installations, while the present invention designs conjunction in itself in structure
Reason, the design of split type and integral structure is carried out to voltage probe, it is ensured that while probe meets eccentric, probe rod is
Vertical.
