Abstract

The utility model discloses a conduction testing device which comprises a device body. The device body is composed of upper and lower layers of flat plates which are parallelly arranged, and comprises a placement platform, which is used for placing a horn, at the upper layer and a testing platform at the lower layer. The center of the placement platform is provided with a circular through hole which is matched with the shape of the placed horn when testing is carried out. A number of metal needles which are electrically connected with a horn testing point are arranged on the testing platform which is at the position corresponding to the underneath of the through hole. A spring column which is used for enabling the placement platform to smoothly move up and down is arranged between the placement platform and the testing platform. According to the utility model, the provided conduction testing device has the advantages of simple structure and convenient use; the horn is placed on the placement platform and then is slightly pressed down, the horn testing point passes through the through hole and then is electrically connected with the metal needles on the testing platform; a control switch is turned on for testing; after testing is completed, a testing result displaying lamp is used to display testing results; whether a product is good or defective can be directly determined; the operation is simple and accurate; the cost is reduced; and the efficiency is improved.

Description

The continuity test device
Technical field
The utility model relates to a kind of continuity test device.
Background technology
Thereby electric automobile horn is to sound by the vibration of metallic membrane.Electric automobile horn is made up of iron core, magnetic coil, contact, armature, diaphragm etc.When the driver presses horn switch, electric current passes through coil through the contact, coil produces magnetic force and inhales lower armature, forces diaphragm to move, and armature moves the contact is disconnected, current interruptions, coil magnetic force disappears, and diaphragm sets back together with armature under self elasticity and spring leaf effect, and contact closure circuit is connected again, electric current produces magnetic force by the contact flowing through coil, repeats above-mentioned action.The diaphragm that circulates so repeatedly constantly vibrates, thereby sends sound equipment.Soundboard and diaphragm rigid attachment, can make the vibration smooth-going sound more melodious.
The terminal conduction property of car horn is very crucial to its function, finally leads the quality of product with directly influencing.The continuity test instrument is the very high portable tester of a kind of automaticity, is specifically designed to the electrical integrity test of device.Continuity test instrument built-in power can convert industrial voltage to safe voltage, and what reality was used is weak electricity measuring, and there is not safety problem in the user.
When loudspeaker being carried out the electrical integrity test, when electrical integrity is tested, need carry out circuit with tester is connected, electric circuit inspection point on the loudspeaker is generally very little, cause connecting difficulty, manually-operated is loaded down with trivial details, can not guarantee the connection accurately and reliably of test circuit, can't test out non-defective unit and defective products accurately, can cause very big influence to test result, and for the bigger loudspeaker of some sizes, because the quality of loudspeaker is less, easily be moved during test, be difficult to the location, can't guarantee the product quality of dispatching from the factory, the production cost height, efficient is low.
The utility model content
The utility model purpose: in order to overcome the deficiencies in the prior art, the technical solution adopted in the utility model is:
The continuity test device comprises apparatus main body, it is characterized in that: described apparatus main body is the two-layer slab construction up and down that be arranged in parallel, comprises the articles holding table that is used for the placement loudspeaker on upper strata and the test platform of lower floor; Place the through hole of the circle that shape matches when described articles holding table center is provided with and tests with loudspeaker, the test board of opposite position is provided with a plurality of metal needles that can be electrically connected with the loudspeaker test point under the described through hole.
Also comprise metal needle arrangement piece, described metal needle settles piece to fixedly connected with test platform by metal needle.
Be provided with between described articles holding table and the test platform for the spring stack of realizing that articles holding table steadily moves up and down.
Be vertically installed with a plurality of for the limited post that limits pan position under the articles holding table on the described test platform.
Described test platform is provided with gauge tap and test result display lamp.
Beneficial effect: the continuity test device that the utility model provides, simple in structure, easy to use, loudspeaker are positioned on the articles holding table, a little down press the loudspeaker test point and pass through hole and be electrically connected with metal needle on the test platform, opening gauge tap tests, test is finished by the test result display lamp and is shown test results, and directly judging product is non-defective unit or defective products, and it is simple and easy accurate to operate, reduce cost, improved efficient.
Description of drawings
Fig. 1 and Fig. 2 are structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further explanation.
As depicted in figs. 1 and 2, for a kind of continuity test device, comprise apparatus main body, it is characterized in that: described apparatus main body is the two-layer slab construction up and down that be arranged in parallel, comprises the articles holding table 1 that is used for the placement loudspeaker on upper strata and the test platform 2 of lower floor; Place the through hole 3 of the circle that shape matches when described articles holding table 1 center is provided with and tests with loudspeaker, the test board of opposite position is provided with a plurality of metal needles 4 that can be electrically connected with the loudspeaker test point under the described through hole 3.Also comprise metal needle arrangement piece 5, described metal needle 4 settles piece 5 to fixedly connected with test platform 2 by metal needle.Be provided with between described articles holding table 1 and the test platform 2 for the spring stack 6 of realizing that articles holding table steadily moves up and down.Be vertically installed with a plurality of for the limited post 7 that limits pan position under the articles holding table on the described test platform 2.Described test platform is provided with gauge tap 8 and test result display lamp 9.
Beneficial effect: the continuity test device that the utility model provides, simple in structure, easy to use, loudspeaker are positioned on the articles holding table 1, a little down press the loudspeaker test point and pass through hole 3 and be electrically connected with metal needle 4 on the test platform 2, opening gauge tap 8 tests, test is finished by test result display lamp 9 and is shown test results, and directly judging product is non-defective unit or defective products, and it is simple and easy accurate to operate, reduce cost, improved efficient.
The above only is preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
