Description

一种检查5芯电缆通路、断路及短路情况的便携式仪器A portable instrument for checking 5-core cables for path, break and short circuits

技术领域technical field

本实用新型属于电缆状态检查装置技术领域,特别是在航天静力试验中,对大量使用的5芯电缆有使用前检查的要求,对5芯电缆通路、断路及短路情况进行检查的仪器。The utility model belongs to the technical field of cable state inspection devices, in particular to an instrument for checking the path, disconnection and short circuit of 5-core cables which are required to be inspected before use in aerospace static tests.

背景技术Background technique

在火箭型号产品的静力学试验中,大量使用5芯电缆在传感器和测量端之间传送信号,如传送力传感器、位移传感器信号等。信号传送线路的通畅与否直接影响到型号产品静力学试验的成功,因此,静力学试验规程中规定:在试验前必须检查所使用的各型电缆通路、断路及短路情况。In the static test of rocket type products, a large number of 5-core cables are used to transmit signals between the sensor and the measuring end, such as transmitting force sensor, displacement sensor signals, etc. The smoothness of the signal transmission line directly affects the success of the static test of the model product. Therefore, the static test procedure stipulates that the passage, open circuit and short circuit of each type of cable used must be checked before the test.

由于火箭型号产品体积较大、5芯电缆的一端已经固定在试验厂房等一些因素,5芯电缆的检查工作通常在试验现场进行,这就需要检查工具具有便携性。通常的检查方法是:将万用表拨到导线通断档位,用表笔测量电缆中某根芯线的通断情况,然后对电缆采取这一方法逐芯线进行检查。但是这种方式较慢,不能直接检查出电缆各芯线之间的短路情况,另外由于万用表的表笔较粗,而所使用的5芯电缆的插头较小,各芯线对应的插针间距窄,检查时操作起来较为不便。当试验使用大量的5芯电缆时,检查工作量大,仅检查工作就耗用大量的时间,进而耽误了试验的进程。Due to some factors such as the large size of the rocket model and the fact that one end of the 5-core cable has been fixed in the test plant, the inspection of the 5-core cable is usually carried out at the test site, which requires the inspection tool to be portable. The usual inspection method is: turn the multimeter to the on-off position of the wire, measure the on-off situation of a certain core wire in the cable with a test pen, and then use this method to check the cable one by one. But this method is slow, and the short circuit between the core wires of the cable cannot be directly checked. In addition, because the pen of the multimeter is relatively thick, and the plug of the 5-core cable used is small, the pin spacing corresponding to each core wire is narrow. , It is more inconvenient to operate during inspection. When a large number of 5-core cables are used in the test, the inspection workload is heavy, and only the inspection work consumes a lot of time, thereby delaying the test process.

因此,要求有一种便携性强、能减小检查时间、易于操作、显示直观的仪器,来进行5芯电缆的检查工作。Therefore, an instrument with strong portability, reduced inspection time, easy operation, and intuitive display is required to inspect the 5-core cable.

When a certain core wire of the cable is connected, press the corresponding contact, the circuit circuit works normally, and only the corresponding light-emitting diode is on; when a certain core wire of the cable is disconnected, press the corresponding contact, the circuit circuit does not work normally, The corresponding light-emitting diodes are not on; when several core wires of the cable are short-circuited, press the contact corresponding to one of the cores, and the light-emitting diodes corresponding to the short-circuited cores are on; when two core wires of the cable are in sequence When it is wrong, press the contact corresponding to one of the cores, the light-emitting diode corresponding to the wrong core is on, and the light-emitting diode corresponding to itself is not on.

依据上述原理,本实用新型如图1所示,包括触点按钮组2、5芯电缆插座甲组3、指示用的发光二级管组4、内置电池充电口5、5芯电缆插座乙组6组成;其中,5芯电缆插座甲组3、5芯电缆插座乙组6为对应设置的两组插座组,上面均包含有3个和待检查5芯电缆1的插头匹配的插座;5芯电缆插座甲组3的每个插座的芯均经过发光二级管组4连接内置电池充电口5内的电源;对应地,5芯电缆插座乙组6的每个插座的芯均经过触点按钮组2连接内置电池充电口5内电源的另一极,5芯电缆插座甲组3、5芯电缆插座乙组6上对应的一组插座的芯连接同一根5芯电缆1的两端。Based on the above principles, the utility model is shown in Figure 1, which includes a contact button group 2, a 5-core cable socket group A 3, a light-emitting diode group 4 for indication, a built-in battery charging port 5, and a 5-core cable socket group B 6 components; Among them, the 5-core cable socket group A 3, the 5-core cable socket group B 6 are two sets of socket groups correspondingly set, all of which contain 3 sockets that match the plug of the 5-core cable 1 to be checked; 5-core The core of each socket of the cable socket group A 3 is connected to the power supply in the built-in battery charging port 5 through the light-emitting diode group 4; correspondingly, the core of each socket of the 5-core cable socket group B 6 passes through the contact button Group 2 is connected to the other pole of the power supply in the built-in battery charging port 5, and the cores of the corresponding group of sockets on the 5-core cable socket group A 3 and the 5-core cable socket B group 6 are connected to the two ends of the same 5-core cable 1.

为便于操作,5芯电缆插座甲组3、5芯电缆插座乙组6在便携式仪器上下对称设置,5芯电缆插座甲组3、5芯电缆插座乙组6之间的便携式仪器的一面作为操作面板,相对应的触点按钮组2的按钮和发光二级管组4的指示灯在操作面板上对称设置。For easy operation, the 5-core cable socket group A 3 and the 5-core cable socket group B 6 are arranged symmetrically up and down on the portable instrument, and the side of the portable instrument between the 5-core cable socket group A 3 and the 5-core cable socket group B 6 is used as the operation The panel, the buttons of the corresponding contact button group 2 and the indicator lights of the light-emitting diode group 4 are arranged symmetrically on the operation panel.

图2是内部电路原理图,其标注定义与图1相同。以此图为例,当触动触点按钮组2的A触点时。如果A触点对应的芯线通路,则A触点所在的电路回路导通,电流将流经发光二极管B,使其发光;如果A触点对应的芯线断路,则A触点所在的电路回路不导通,发光二极管B不亮;如果A触点对应的芯线和其它芯线短路,不但发光二极管B亮,其他发光二极管也亮,从而得知那几条芯线短路。Figure 2 is a schematic diagram of the internal circuit, and its label definitions are the same as those in Figure 1. Take this picture as an example, when contact A of contact button group 2 is touched. If the core wire corresponding to the A contact is open, the circuit where the A contact is located is turned on, and the current will flow through the light-emitting diode B to make it glow; if the core wire corresponding to the A contact is disconnected, the circuit where the A contact is located If the circuit is not conducting, LED B is not bright; if the core wire corresponding to A contact is short-circuited with other core wires, not only LED B is on, but also other LEDs are on, so it is known that those core wires are short-circuited.

检查时,5芯电缆1根据其插头的不同分别连接在5芯电缆插座甲组3中的某个插座和5芯电缆插座乙组6对应的插座上;分别触动触点按钮组2的每个触点,根据指示用的发光二级管组4的亮灭情况来判断对应芯线的通路断路和短路情况。During inspection, the 5-core cable 1 is connected to a certain socket in Group A 3 of the 5-core cable socket and the corresponding socket in Group B 6 of the 5-core cable socket according to the different plugs; touch each button of the contact button group 2 respectively.
