Description

Technical Field

[0001] The invention belongs to the technical field of electrical detection, and in particular relates to an auxiliary tooling for electrical detection of a missile. Background Art

[0002] Missile electrical testing is a key link in the trial production process. Before leaving the factory, it is necessary to conduct electrical testing to confirm that the product is in normal condition. At present, missile electrical testing includes two parts: static resistance testing and dynamic performance testing. For safety reasons, static resistance testing is generally performed first, and dynamic performance testing is performed after the state is normal. The traditional testing process is: 1) Connect the missile and the test instrument through a static test cable, and then measure the specific resistance of the corresponding terminal; 2) Select the corresponding dynamic test cable, confirm the open circuit and short circuit of the corresponding ignition channel, connect the missile and the test equipment through the test cable, and then test the dynamic performance of the product. This method results in a large number of cables in the electrical testing process of the missile, which makes it difficult to manage the test cables. For missiles with the same interface model but different terminal definitions, there are certain safety hazards in the dynamic testing process when the test cable is selected incorrectly; 3) Static testing requires measuring the resistance of the ignition channel, and the dynamic testing process requires short-circuiting the ignition channel, resulting in the need to distinguish between static testing and dynamic testing of the cables connected to the missile. Summary of the invention

[0003] In order to overcome the deficiencies of the prior art, the present invention provides a missile electrical detection auxiliary tooling, which uses a transfer cable to connect the product to be tested with the input interface, the input interface, the output interface, the short-circuit interface and the switch assembly are connected by wires inside the box, and the output interface is connected to the detection instrument or equipment through a transfer cable, thereby forming a physical connection between the detection instrument or equipment and the missile interface. By controlling the corresponding switch state in the knob switch assembly, the on-off control of the corresponding terminal of the missile to the detection instrument or equipment can be realized, and the on-off control of the corresponding terminal of the missile to the short-circuit interface can be realized, thereby achieving short-circuit control of the corresponding terminal of the missile. The device is simple and practical, and has broad application prospects and promotion value in missile electrical detection.

[0009] By controlling the on / off status of each knob switch in the knob switch array to access the output interface, electrical testing can be completed in conjunction with corresponding testing instruments or equipment.

[0010] By controlling the on-off state of each knob switch in the knob switch array, the specific terminals of the input interface connected to the No. 1 short-circuit interface and the No. 2 short-circuit interface are selected, thereby realizing short-circuit protection for the missile-related terminals.

[0011] Preferably, when the missile electrical detection auxiliary tooling is in use and the number of missile interface terminals exceeds 100, the No. 1 adapter cable is prepared as a "one-to-many type", in which the interface model at one end matches the missile interface, and the model of each branch interface at the multiple ends needs to match the input interface of the auxiliary tooling; the No. 2 adapter cable is prepared as a "one-to-many type", in which the interface model at one end matches the detection instrument or equipment interface, and the model of each branch interface at the multiple ends needs to match the output interface of the auxiliary tooling.

[0021] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0022] The technical problem to be solved by the present invention is: how to provide a missile electrical detection auxiliary tooling.

[0023] In order to solve the above technical problems, the present invention provides a missile electrical detection auxiliary tooling, comprising: a tooling box 1, a knob switch array 2, an input interface 3, an output interface 4, a No. 1 short-circuit interface 5, a No. 2 short-circuit interface 6, a No. 1 adapter cable 7 and a No. 2 adapter cable 8;

[0024] The tooling box 1 is a mounting body for the knob switch array 2, the input interface 3, the output interface 4, the No. 1 short-circuit interface 5 and the No. 2 short-circuit interface 6, and is used for the installation and fixation of various components;

[0025] The input interface 3, the knob switch array 2, the No. 1 short-circuit interface 5, the No. 2 short-circuit interface 6 and the output interface 4 are connected inside the tooling box 1 through wires; the missile is physically connected to the input interface 3 through the No. 1 adapter cable 7; the detection instrument or equipment is connected to the output interface 4 through the No. 2 adapter cable 8 to achieve the physical connection between the detection instrument or equipment and the input interface 3, and finally the connection between the missile and the detection instrument or equipment is achieved.

[0026] The rotary switch array 2 includes 100 rotary switches, which are distributed in a 10x10 array, numbered 1 to 100. Each rotary switch is in an independent state. The model of each switch is a five-pin four-gear model, wherein the common pin is connected to the corresponding terminal of the input interface 3, and the first three of the remaining four pins are connected to the corresponding terminal of the output interface 4, the No. 1 short-circuit interface 5, and the No. 2 short-circuit interface 6, respectively, and the fourth pin is not connected at all.

[0027] The input interface 3 and the output interface 4 are both electrical connectors of model J30J-100ZKP;

[0028] No. 1 short-circuit interface 5 and No. 2 short-circuit interface 6 are both banana sockets;

[0029] One end of the No. 1 adapter cable 7 is an electrical connector of model J30J-100TJL, and the model of the other end needs to match the interface of the missile to be tested;

[0030] One end of the No. 2 transfer cable 8 is an electrical connector of model J30J-100TJL, and the model of the other end needs to match the interface of the detection instrument or equipment.

[0031] The input interface 3 is selected to be connected to the output interface 4 by controlling the on / off state of each knob switch in the knob switch array 2, and the electrical test is completed by cooperating with corresponding testing instruments or equipment.

[0032] The specific terminals of the input interface 3 connected to the No. 1 short-circuit interface 5 and the No. 2 short-circuit interface 6 are selected by controlling the on-off state of each knob switch in the knob switch array 2, thereby realizing short-circuit protection for the missile-related terminals.

[0033] Among them, if the number of missile interface terminals exceeds 100 during use, the No. 1 adapter cable 7 can be prepared as a "one-to-multiple type", in which the interface model at one end matches the missile interface, and each branch interface model at the multiple ends needs to match the auxiliary tooling input interface 3. The No. 2 adapter cable 8 also needs to be prepared as a "one-to-multiple type", in which the interface model at one end matches the detection instrument or equipment interface, and each branch interface model at the multiple ends needs to match the auxiliary tooling output interface 4.

[0034] Example:

[0035] (1) Static resistance detection:

[0036] 1) Check the number of missile interface terminals and select auxiliary tooling;

[0037] a) If the number of auxiliary tooling interface terminals does not exceed the number, a single auxiliary tooling can be used directly;

[0038] b) If the number of auxiliary tooling interface terminals exceeds the limit, select the corresponding number of auxiliary tooling based on the actual situation.

[0039] 2) Confirm that each knob switch in the knob switch array is in the first gear, that is, each terminal of the input interface is connected to the corresponding terminal of the output interface;

[0040] 3) Use No. 1 adapter cable to connect the missile to be tested, and use No. 2 adapter cable to connect the static resistance detection instrument or equipment. If the cable is a one-to-many type, pay attention to the terminal number when connecting;

[0041] 4) The static resistance detection instrument or equipment is used to detect the static resistance of the missile, and then the data is recorded and retained.

[0042] The interface of a certain type of missile is J30J-144TJL, and the static resistance value test is carried out on it as the product to be tested. The example is as follows:

[0043] 1) It can be seen from the interface model of the product to be tested that two auxiliary toolings are required to be used together;

[0044] 2) Confirm that each rotary switch in the rotary switch array connects each terminal of the input interface to the corresponding terminal of the output interface;

[0045] 3) Use the one-to-two adapter cable No. 1 and No. 2 to connect the product to be tested and the testing instrument or equipment. Auxiliary tooling 1 corresponds to terminals 1 to 100 of the product to be tested, and terminals 1 to 44 of auxiliary tooling 2 correspond to terminals 101 to 144 of the product to be tested;

[0046] 4) The static resistance detection instrument or equipment is used to detect the static resistance of the missile, and then the data is recorded and retained.

[0047] (2) Dynamic performance testing:

[0048] After the static resistance test is qualified, the dynamic performance test of the missile power-on is required to ensure that the product power-on, control, communication, execution and other functions are normal. During the power-on test, the ignition of the electric pyrotechnics needs to be short-circuited. Generally, missiles include ground ignition and on-missile ignition. During the short-circuit protection process, they need to be short-circuited according to their categories.

[0049] 1) Check the number of missile interface terminals and select auxiliary tooling;

[0050] a) If the number of auxiliary tooling interface terminals does not exceed the number, a single auxiliary tooling can be used directly;

[0051] b) If the number of auxiliary tooling interface terminals exceeds the limit, select the corresponding number of auxiliary tooling based on the actual situation.

[0052] 2) Use the test leads to connect the No. 1 short-circuit interface and No. 2 short-circuit interface of each auxiliary tool with the same name (this step is not required for a single auxiliary tool);

[0053] 3) Confirm that each knob switch in the knob switch array is in the first gear, that is, each terminal of the input interface is connected to the corresponding terminal of the output interface;

[0054] 4) According to the actual situation of the missile, sort out the ground ignition and the corresponding terminals of the ignition ground, and control the corresponding knob switch to put it in the second or third gear;

[0055] 5) According to the actual situation of the missile, sort out the corresponding terminals of the missile ignition and ignition ground, and control the corresponding knob switch to put it in the third gear or the second gear (to clearly require that the ground and the missile ignition share the same ground, the two ignition short circuits use different gears);

[0056] 6) Use No. 1 adapter cable to connect the missile to be tested, and use No. 2 adapter cable to connect the static performance test instrument or equipment. If the cable is a one-to-many type, pay attention to the terminal number when connecting;

[0057] 7) Complete dynamic performance testing of the missile through dynamic performance testing instruments or equipment, and then complete and retain the data.

[0058] The interface of a certain type of missile is J30J-144TJL. The terminals corresponding to ground ignition and ignition ground are 15, 16, 33, 34, 65, and 66 respectively. The terminals corresponding to missile ignition and ignition ground are 89, 90, 121, 122, 139, and 140 respectively. The dynamic performance test is carried out on it as the product to be tested. The example is as follows:

[0059] 1) It can be seen from the interface model of the product to be tested that two auxiliary toolings are required to be used together;

[0060] 2) Use the test lead to connect the No. 1 short-circuit interface and No. 2 short-circuit interface of the two auxiliary tools with the same name;

[0061] 3) Confirm that each knob switch in the knob switch array is in the first gear, that is, each terminal of the input interface is connected to the corresponding terminal of the output interface;

[0062] 4) Control the knob switches numbered 15, 16, 33, 34, 65, and 66 on the auxiliary tooling 1 to the second gear;

[0063] 5) Control the knob switches with serial numbers 89 and 90 on the auxiliary tooling 1 to set them to the third gear, and control the knob switches with serial numbers 21, 22, 39, and 40 on the auxiliary tooling 2 to set them to the third gear;

[0064] 6) Use the one-to-two adapter cable No. 1 and No. 2 to connect the product to be tested and the testing instrument or equipment. Auxiliary tooling 1 corresponds to terminals 1 to 100 of the product to be tested, and terminals 1 to 44 of auxiliary tooling 2 correspond to terminals 101 to 144 of the product to be tested;

[0065] 7) Complete dynamic performance testing of the missile through dynamic performance testing instruments or equipment, and then complete and retain the data.

[0066] The present invention has the following technical features:

[0067] (1) The tooling can realize the physical connection between different missiles and detection instruments or equipment by replacing the No. 1 adapter cable and No. 2 adapter cable of the corresponding interface model. The on-off status of each terminal is controlled by the knob switch array, which is universal for missile electrical detection.

[0068] (2) The tooling controls the short-circuit state of the corresponding terminal of the connected missile through a knob switch, and can implement short-circuit protection for the corresponding channel during the detection process; by setting two short-circuit interfaces, short-circuit protection in two states can be implemented.

[0069] (3) The tooling is designed to split the No. 1 adapter cable and the No. 2 adapter cable into multiple types, and then use the test lead wiring to connect the corresponding No. 1 short-circuit interface and No. 2 short-circuit interface with the same name, so that multiple auxiliary tooling can be used together, which has strong scalability.

[0070] (4) The tooling is connected to the missile and the auxiliary tooling via No. 1 adapter cable. The tooling can be used as a short-circuit protection plug by controlling the corresponding knob switch.

[0071] Therefore, compared with the prior art, the tooling can achieve the following technical effects:

[0072] (1) The tooling can be used for static resistance testing of missiles, as well as dynamic performance testing.

[0073] (2) The tooling can control the on / off status of each switch in the knob switch array, so that the corresponding terminals of the missile are in a short-circuit protection state during the dynamic performance inspection process.

[0074] (3) The tooling effectively reduces the number of cables in the missile electrical inspection process. Missiles with the same interface model can use the same adapter cable, making the corresponding cables universal.

[0075] (4) The tool can be equipped with a multi-point cable, test lead wiring, and used in conjunction with multiple tools to perform electrical testing on missiles whose terminals are much larger than the number of tool interface terminals.
