The front surface of the testing joint-changeable testing device is provided with a testing socket which is engaged with the testing joint of an object which is tested. The back surface of the testing joint-changeable testing device is provided with a row needle used for being inserted into the row needle seat of the testing device. The pattern assembly is provided with a plurality of screw holes, and the testing pattern assembly is fixed on the testing device by the screw holes. The testing device can select the suitable testing pattern assembly according to the requirements of different joints which are tested. The testing pattern assembly can be arranged on a connecting socket which is reserved by the testing device in advance, and the pattern assembly is fixed on the testing device.

Description

Joint-changeable testing device

The utility model is the proving installation about a kind of replaceable test splice, particularly can answer various different test splice demands about a kind of, and the testing tool of random replacing test splice module.

Known proving installation is when being connected test with determinand, often because determinand joint and proving installation joint different, and need are made the conversion equipment between a determinand and proving installation joint in addition, the user needs how time-consuming looking on the different X-overs thus, and this conversion equipment is not only changed difficult when dismounting, it is big to take up room, line impedance increases, and when changing different determinand, more want spended time reconfiguring at line, inconvenience when all shortcomings not only are increased in test, and more need expend a large amount of manpowers in the conversion of keeping various different joints and maintenance, above-mentioned every shortcoming all can obtain suitable solution on the utility model.

The purpose of this utility model is promptly providing a kind of can the utilization easily to change the testing tool that the test splice module reaches the replacing test splice, this instrument can be equipped with different types of joint module, test splice according to different determinands needs, select suitable joint module, it is installed on the panel of instrument, the determinand joint can directly be inserted on the test bench of this module, the tester not only need not to make in addition the test web member, and owing to need not wiring between determinand and testing tool, so line impedance is low, the loss minimum, the accuracy of corresponding resulting test data and fiduciary level all can improve greatly, save the space in addition, the joint module is changed easily, is convenient to eliminate trade-in, testing cost is cheap and can utilize and design connection mode in advance, contacting reliably etc., all is that the utility model is better than known emphasis.

The utility model is realized by following scheme, in device, be provided with the test splice module, it can comply with different joint demands to be measured, be made into the different modules of several piece, be provided with at test module rear side and connect row's pin, be used for being connected, comprise the fixed screw group in addition with row's needle socket in the proving installation, be used for the test module is fixed on the proving installation, and the circulation of high electric current between conducting determinand and the proving installation.

In order further to understand feature of the present utility model and technology contents, can consult following about detailed description of the present utility model and accompanying drawing.

Description of drawings:

Fig. 1 is that known power supply testing device uses the enforcement illustration;

Fig. 2 is proving installation of the present utility model and test splice module conversion synoptic diagram;

Fig. 3 A is a changeable type test splice module front view of the present utility model;

Fig. 3 B is a changeable type test splice module rear view of the present utility model;

Fig. 4 is that changeable type test splice module of the present utility model is used in the use embodiment on the proving installation.

Shown in Figure 1, for known proving installation uses embodiment; The test mode of commonly using is to make a joint conversion web member 11 earlier, then the joint to be measured 12 of determinand 14 is received on the joint conversion web member 11, relative line relation between all joints to be measured 12 and the test splice 15 of proving installation 13, all on joint bridgeware 11, connect in advance in advance, again the connecting line between each web member and testing tool is connected one by one, so test connected mode, line impedance height between not only time-consuming but also determinand and power supply testing device, measured data accuracy and fiduciary level all reduce greatly; Test splice 15 is using the phenomenons such as producing loose contact that also can wear out long afterwards in addition, when changing test splice 15, general way is earlier panel to be taken apart then from the rear of panel the instrument internal circuit to be removed the test splice that renews again in advance, program is quite miscellaneous, simultaneously whenever changing when surveying new determinand, whole web member and connecting line need to do again configuration again again, various web member can take many spaces when collecting too, from the above, known test mode also has the improved shortcoming of many needs.

Shown in Fig. 2,3A, the 3B, be proving installation of the present utility model and the conversion of test splice module synoptic diagram, test splice module front view and rear view; Characteristics of the present utility model are known proving installation input adapter to be designed to various test splice module 21, the front of this test splice module 21 is test jack 31, can engage with the test splice 12 of determinand, in addition 32 on row's pin at its back side can be inserted on the row-needle receptacle 26 on the joint module inner panel 24 on the testing tool 22, and this test splice module 21 is fixed on the panel of testing tool 22 with screw 25, in addition, screw 25 this can also as connect and conducting determinand and proving installation between the logical usefulness of high-current flow, when our determinand has different joints to be measured, we only need to select suitable test splice module 21, and original test splice module 21 pulled down, change the test splice module 21 of new selection into, can carry out next testing procedure immediately, in the linking of testing process, do not have any interruption, the test web member, connecting lines etc. do not need to make again more yet, and the accuracy of test data and reliability also can improve accordingly greatly, on manpower and cost, also can obtain effective control, when changing old test splice module 21, also no longer need to finish in the future through complicated demounting procedure.

Shown in Figure 4, for illustration is implemented in the use that changeable type test splice module of the present utility model is used on the proving installation; By we can recognize fully that the utility model can improve known proving installation really in practicality in the diagram, the test web member 21 that wherein has a replaceable test splice module on the testing tool 22, this web member simply is easy to do, make fully at the joint of determinand 14, determinand 14 as shown in the figure is the power supply unit in the PC, so its joint is several row's adapters, the joint web member made at this power supply unit can connect its joint easily, do not take up space fully and can not waste the time of other wiring.
