Description
Technical field
The present invention relates to a kind of portable electric attachment means.
Background technology
Electric car is liked with its energy-conserving and environment-protective, convenient advantage of going on a journey by people, with the increase of electric car quantity,
The demand of charging pile for electric vehicle also increases year by year.
Charging pile needs to carry out voltage-withstand test and system test before dispatching from the factory, and is needed during test on disposable measurement charging pile
The Current Voltage of 13 points, wherein the Current Voltage of 12 points is measured from the terminal block screw on pcb board, another
The Current Voltage of point is measured from the lock-screw of pcb board.The structure of pcb board is as shown in figure 1, have joint Terminal on pcb board 1
12 terminal block screws 13 are arranged at intervals with seat 11, union end stroma 11, the corner of pcb board offers screw hole 14, peace
Pcb board is fixed in the main body of charging pile by lock-screw during dress.During test, wherein ten two points of Current Voltage is from 12
Measured on terminal block screw, the Current Voltage of another point is measured from the lock-screw of union end stroma side, 12
Terminal block screw and one of lock-screw constitute 13 calibrating terminals to be tested.Test side commonly used in the prior art
Method is to clamp each calibrating terminal respectively using crocodile clip, and crocodile clip is connected by lead with test device.This method is not only imitated
Rate is relatively low, and due to smooth at the top of screw cap, is available for the area clamped small, and easily folder collapses crocodile clip, and then influences test effect
Rate and production efficiency.Also someone is tested using gantry frame structure in the prior art, during test, and charging pile is put into portal frame
On base platform, the crossbeam of portal frame is provided with quick-speed jigs, and the quick-speed jigs first line of a couplet is connected to 13 elastic probes, puts down quick
Fixture, 13 probes are just press respectively against on each calibrating terminal, realize that conductive contact coordinates.Although this method of testing can
OK, but there are problems, such as test needs charging pile being carried on portal frame base every time, it is not only bothersome laborious, and
In handling process, easily cause surface tear, fall the problems such as painting.
Summary problem, needs a kind of portable electric attachment means badly, it is possible to increase testing efficiency in the prior art.Such as award
A kind of notification number test fixture disclosed in CN102818917B Chinese invention patent is weighed, the test fixture is included by two pieces of phases
The connecting plate and a reciprocating mechanism with hook of the mainboard composition connected, reciprocating mechanism are arranged with by two
The guide pillar of back-moving spring is arranged on connecting plate, and one is rotatablely equipped with connecting plate is used for linking up with the buckle matched,
When reciprocating mechanism is moved down, hook is mounted with buckle coordinates the positioning for realizing reciprocating mechanism, and buckle is rotated with hanging
Hook departs from, and reciprocating mechanism resets in the presence of back-moving spring.Reciprocating mechanism includes the pressing plate with external interface
With the needle plate being connected on the downside of pressing plate, the probe on needle plate electrically connects the electric signal on calibrating terminal with external interface.Should
Test fixture in use, by connecting plate inserting to tested terminal bottom, press down on hook on pressing plate, reciprocating mechanism with
It is clasped, the probe on needle plate and tested terminal good contact.The test fixture is although portable, but the test fixture needs
The connecting plate for being provided for being connected with terminal to be tested is not only needed, and is also needed to reciprocating mechanism by being cased with spring
Guide upright post be arranged on connecting plate on, in addition it is also necessary on reciprocating mechanism set hook, on connecting plate be rotatablely installed card
Button and the connecting rod for pulling buckle to rotate, the structure in turn resulting in the test fixture are complex.
