Abstract
Provided by the utility model is a detection device for a power plug. The detection device comprises a test machine and also a contact switch. The test machine comprises a testing socket and a control circuit board; the contact switch is arranged on the testing socket and is connected with the control circuit; and when a plug to be tested is completely inserted into the testing socket, the plug to be tested presses the contact switch to get the contact switch conducted. According to the utility model, under the condition that the structure and performance of a conventional testing device remain unchanged and undamaged, the contact switch is additionally arranged so that glue-punching unqualified products are easily detected, the quality problem difficult to find is effectively solved at a low cost, and the product quality is improved.
Description
Technical field
The utility model relates to the detection technique field of wire harness, relates in particular to a kind of bad pick-up unit that needs the attaching plug female of injection molding.
Background technology
The current attaching plug for needing injection molding, particularly female have a kind of commonplace bad phenomenon " rushing glue ".And the defective products that this bad phenomenon causes is difficult to be found in existing detection method and equipment, will be likely that defective products flows out like this, thereby causes very serious quality problem.
In the product test process adopting at present, as long as plug is inserted to test jack, then start test machine and test.Specification product are distinguished as shown in Figure 1 and Figure 2 with the design sketch that the substandard product that rushes glue inserts after test jack.From the test schematic diagram (Fig. 1) of specification product, can see that qualified plug 2 has contacted completely with test jack 1, at this moment testing conductive performance is qualified.From rushing test schematic diagram (Fig. 2 of the substandard product of glue, in figure, plug 3 is for rushing the defective female of glue, wherein black part is divided and is represented to enter the plastic cement in plug hole) can see that the plug 3 that rushes glue can not completely contact and put in place with test jack 1, but partially conductive position contacts, at this moment testing conductive performance is also qualified.So just there is the phenomenon that defective products may flow out as non-defective unit.Thereby, be necessary to propose a solution, to reduce the outflow of defective products.
Summary of the invention
The purpose of this utility model is to provide a kind of pick-up unit of attaching plug, effectively detects the defective products that has " rushing glue " phenomenon, stops this defective products and comes into the market, and effectively improves product quality.
The purpose of this utility model is achieved through the following technical solutions:
A pick-up unit for attaching plug, comprises test machine, and this test machine comprises test jack and control circuit board; This pick-up unit also comprises contact switch, and this contact switch is located in described test jack and with control circuit board and is connected, and when plug to be measured inserts test jack completely, plug to be measured is depressed contact switch and made its connection.
Wherein, described test machine also comprises alarm unit, is connected with control circuit board, at plug to be measured, inserts test jack and contact switch access failure alarm.
Wherein, the size of described contact switch and structure and test jack are suitable.
Compared with prior art, the utility model embodiment has following beneficial effect:
The utility model is not in the situation that changing and destroy existing testing apparatus structure and performance, by increasing by a contact switch, detect easily the defective products that rushes glue, with very little cost, effectively solve indiscoverable quality problem, improved the quality of product.
Accompanying drawing explanation
Fig. 1 is the test schematic diagram of specification product in prior art.
Fig. 2 is the test schematic diagram that has the substandard product of " rushing glue " phenomenon in prior art.
Fig. 3 is the test schematic diagram of specification product in the utility model embodiment.
Fig. 4 is the test schematic diagram that has the substandard product of " rushing glue " phenomenon in the utility model embodiment.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
In the present embodiment, for the pick-up unit of attaching plug, comprise test machine, in the test jack of test machine, have additional contact switch, the model of contact switch, size can freely be selected according to the size of test jack, shape and installation site.Contact switch is connected with the control circuit of test machine, and when contact switch is connected, the product of test is only qualified product, otherwise test machine reports to the police to be shown as substandard product.
As shown in Figure 3, if plug to be measured is specification product, when test, plug 2 to be measured will be depressed contact switch 4 and make its position A connection, and test machine is not reported to the police, and at this moment plug 2 to be measured is exactly not rush glue.As shown in Figure 4, if plug to be measured rushes glue, when test, plug 3 to be measured, owing to can not being inserted into position completely, connects its position A so can not depress contact switch 4, and while at this moment testing, test machine will be reported to the police, and shows that this product is defective products.So just can detect easily the defective products that rushes glue.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
