Description

A kind of automobile lamp mould group test fixture

Technical field

The utility model relates to test fixture structures, and in particular to a kind of test fixture of automobile lamp mould group.

Background technique

The car light mould group of automobile generally all can include the lamp group of several different function such as high beam, dipped headlight and clearance light, It before factory, needs to test each lamp group, to ensure that it being capable of normal luminous.There are two current test indexs, and one Be test voltage be 13.5 V when, respectively by each lamp group access test circuit in, it is desirable that each lamp group can normal luminous, Second is that requiring under 16V test voltage, series connection enters the test resistance of 260 Ω in test circuit, requires distance light at this time Lamp and dipped headlight cannot be lit, and two test car light mould groups up to standard are qualified product, filter out the lamp group that cannot be shone It eliminates, to ensure product quality of dispatching from the factory.Need to so carry out whether having under the different situations such as test resistance under different test voltages Multiple groups test experiments.Each lamp group both ends of car light mould group are connected separately with two conducting wires, at present when testing, respectively It goes to be attached respectively with the conducting wire at one of lamp group both ends with the cathode power supply line of test power supply and anode power cord, check Whether it works normally, and inspection removes power supply line from this group of lamp after finishing a lamp group, then removes connection another set lamp, It repeats repeatedly, until completing the test experiments of each lamp group.But aforesaid operations due to one group of lamp of every test just It needs to carry out conducting wire and tests the connection of power supply operation, the intricate operation and inconvenient for operation, so usually having worker such as to remove Conducting wire note is mixed or test leakage tries the case where certain organizes lamp generation, the accuracy of test result is influenced, influences the quality of factory car light, So needing a kind of test fixture easy to operate to detect to the car light mould group before factory.

Utility model content

The purpose of the utility model is to provide a kind of automobile lamp mould group test fixture, the test fixture structure operation is simple It is convenient, it is not easy to wrong survey, test leakage situation occur, significantly reduce labor intensity, and accuracy rate is high.

To achieve the goals above, the utility model adopts the following technical scheme:

A kind of automobile lamp mould group test fixture, including shell are set on the housing there are three sub switch is turned round, from shell Cathode power supply line, anode power cord are drawn in side, and the first p-wire, the second p-wire, third test are drawn in the other side of shell Line and public p-wire, the anode power cord are connect in shell with the public p-wire, and described first turns round sub switch End of incoming cables is connected with cathode power supply line, and the first leading-out terminal of the first torsion sub switch is directly connected with the first p-wire, and first turns round son Second leading-out terminal of switch is connected through conducting wire with the end of incoming cables of the second torsional angle, and the first leading-out terminal of the second torsion sub switch is straight through conducting wire It connects the end of incoming cables for turning round sub switch with third to be connected, the second leading-out terminal of the second torsion sub switch is connected with the test resistance of 260 Ω, surveys The end of incoming cables that examination resistance and third turn round sub switch is connected, the first leading-out terminal of third torsion sub switch directly with third p-wire phase Even, third turns round the second leading-out terminal and the 4th p-wire line of sub switch, and first p-wire, the second p-wire, third are surveyed Examination line and public p-wire are connected with test plug respectively when in use.

Preferably, the cathode power supply line and anode power cord are connected with the anode and cathode of variable power supply respectively, described Variable power supply provides 13.5V and 16V voltage.

In above-mentioned technical proposal, positive and negative anodes are directly connect with variable power supply, save the operation of replacement power supply, convenient and efficient； And this test fixture is utilized, only needs that the high beam, dipped headlight and clearance light of car light mould group are disposably respectively connected to test work Then test experiments can be fully completed by dress by controlling 3 torsion sub switchs, complete a test with regard to needing to tear open without every Dress recombination circuit, it is convenient and efficient, and test leakage or wrong survey phenomenon are less likely to occur, it is greatly saved manpower and material resources.
