Abstract
The utility model relates to an instrument clamping apparatus used for a test board. The instrument clamping apparatus used for the test board comprises a test board front panel and a test board bottom panel. The instrument clamping apparatus used for the test board is characterized in that a connecting terminal is fixed on the back surface of the test board bottom panel; spring probes which are consistent with instrument connectors in terms of quantity are fixedly connected with the connecting terminal; internal ends of the spring probes are connected with a probe fixing circuit board; the probe fixing circuit board is fixedly installed on the connecting terminal; and buckles are arranged on the test board front panel. The instrument clamping apparatus used for the test board is advantageous in that: through a clamping mode of a spring probe structure, connection directions do not need to be corrected during the clamping of the instrument; only the instrument needs to be aligned with a concave pit in the front panel and then be pressed into the concave pit; the clamping speed is fast; the connection is in place; a contact type substitutes a plug-in type; problems of labor consuming when instruments are clamped by connectors and the instruments are pulled out from the connectors in the prior art are avoided; and the service life is simultaneously substantially raised.
Description
Technical field
This patent belongs to the instrument detection technique field of farm machinery, particularly relates to a kind of test board instrument chucking device.
Background technology
Agricultural machinery instrument need to carry out functional test when producing on test board.In agricultural machinery instrument test board, being installed of instrument is often identical with actual agricultural machinery mounting means at present, adopts and patches the 26 needle connectors connections that fastness is very strong.When 26 needle connectors connect, need to first determine closure, then wire harness terminal adapter female end firmly be inserted to Instrument connection device male end.Once and insert to throw off effort more, the work efficiency while having caused Meter Test is low.In addition the plug number of times connecting line that too much also easily comes off.
Summary of the invention
This patent provides a kind of test board instrument chucking device for solving the technical matters existing in known technology, and this device can conveniently be realized being installed of instrument.
A kind of test board instrument chucking device, comprise test board front panel and test board base plate, it is characterized in that: the back side of test board base plate is fixed with splicing ear, on splicing ear, be fixedly connected with the spring probe that quantity is consistent with instrument connector quantity, the inner of spring probe is connected with probe fixing circuit board, probe fixing circuit board be fixedly mounted with splicing ear on, test board front panel is provided with pit, the edge of pit is provided with buckle.
Advantage and good effect that this patent has are:
Because this patent adopts technique scheme, by the mode that is installed of spring probe structure, while being installed instrument, without correcting closure, as long as instrument alignment guide is pressed into, the speed that is installed is fast, and connection puts in place.With contact, substituted plug-in type, the problem of effort while having avoided instrument of the prior art and connector are installed and extract also improves serviceable life simultaneously greatly.

Fig. 1 is the structural representation of this patent;
In figure: 1, instrument connector; 2, instrument; 3, test board front panel; 4, test board base plate; 5, splicing ear; 6, probe fixing circuit board; 7, spring probe; 8, control panel; 9, buckle.
Embodiment
For further understanding innovation and creation content, the Characteristic of this patent, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
As shown in Figure 1,
A kind of test board instrument chucking device, comprise test board front panel 3 and test board base plate 4, test board front panel 3 is provided with a pit, the size and dimension of pit is consistent with tested instrument 2, the back side of test board base plate is fixed with splicing ear 5, on splicing ear, be fixedly connected with the spring probe 7 that quantity is consistent with instrument connector quantity, the distribution of spring probe 7 also distributes consistent with the instrument connector 1 in instrument, the inner of spring probe is connected with probe fixing circuit board 6, probe fixing circuit board be fixedly mounted with splicing ear on
In order to prevent that instrument is pressed onto a rear instrument and ejects under the effect of spring probe elastic force, buckle 9 is installed on test board front panel.
The operating principle of this patent is:
The formed guide rail guiding of the pit of instrument 2 on test board front panel 3 is accurately pressed into, 26 pin instrument connectors 1 of instrument 2 accurately push splicing ear 5, because the distribution of spring probe on splicing ear is consistent with the distribution of instrument connector in instrument, so when instrument is pressed into, instrument connector is just in time aimed at the probe in splicing ear hole.Because spring probe has elasticity, thus instrument connector after spring probe is compressed to a segment distance, instrument connector fully contacts with probe.Spring probe 7 is welded on probe fixing circuit board 6, and probe fixing circuit board 6 is together fixed on test board base plate 4 with splicing ear 5.The end of spring probe 7 is connected on control panel 8 by line, thereby has realized the electrical connection to Meter Test.After being pressed into, instrument is stuck with buckle instrument.After having tested, unclamp buckle, instrument ejects voluntarily.
Although by reference to the accompanying drawings the preferred embodiment of this patent is described above; but this patent is not limited to above-mentioned embodiment; above-mentioned embodiment is only schematic; be not restrictive; those of ordinary skill in the art is under the enlightenment of this patent; not departing from the scope situation that this patent aim and claim protect, can also make a lot of forms, within these all belong to the protection domain of this patent.
