DETAILED DESCRIPTION
[0038] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0039] As described in the background technology, during the assembly of a spacecraft, a large number of thermal control components such as heaters, thermistors, and thermocouples need to be pasted on the cabin. After pasting, the inspector needs to measure the internal resistance and insulation resistance of the thermal control component. During the measurement process, the position needs to be changed frequently. However, the traditional resistance measuring device is large in size and is very inconvenient to move.
[0040] To solve the above problems, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 After a thorough analysis of the usage scenarios of the assembled multimeter 140, combined with the actual situation of the measurement work, the operability of the device, the measurement accuracy and other factors, the utility model provides a portable resistance measuring device, including a left-hand glove 110, a right-hand glove 120, a wristband 130 and a multimeter 140. Among them, the left-hand glove 110 is worn on the left hand of the human body. The right-hand glove 120 is worn on the right hand of the human body. The wristband 130 is worn on the wrist of the left hand of the human body. A first electrical contact 111 is provided on the left-hand glove 110, and a second electrical contact 121 is provided on the right-hand glove 120. The multimeter 140 is detachably mounted on the wristband 130 to be worn on the wrist of the left hand of the human body. The positive pole of the multimeter 140 can be connected or disconnected with the first electrical contact 111 through the first connector 150. The negative pole of the multimeter 140 can be connected or disconnected with the second electrical contact 121 through the second connector 160.
[0041] Before measuring the thermal control element 200, a small multimeter 140 with high measurement accuracy is first worn on the wrist of the left hand of the human body through the wristband 130. Then, the left hand wears the left hand glove 110, and the right hand wears the right hand glove 120. After that, the positive pole of the multimeter 140 is connected to the first electrical contact 111 through the first connector 150, and the negative pole is connected to the second electrical contact 121 through the second connector 160. When measuring the internal resistance value of the thermal control element 200, the first electrical contact 111 is made to contact the lead at one end of the thermal control element 200, and the second electrical contact 121 is made to contact the lead at the other end of the thermal control element 200, and the displayed value of the multimeter 140 is read. When measuring the insulation resistance value of the thermal control element 200, the first contact is made to contact the lead at one end of the thermal control element 200, and the second electrical contact 121 is made to contact the insulating cabin, and the displayed value of the multimeter 140 is read. Compared with traditional resistance measuring devices, it has a wearable function, which is very flexible and convenient when the position is frequently transferred. Since the multimeter 140 can be worn on the wrist, the possibility of the multimeter 140 falling and damaging other components on the cabin is reduced. When transferring positions, the cables used by the portable resistance measuring device are stored in the left arm sleeve, chest and right arm sleeve of the work clothes, and are not easy to get hooked with the upper cabin components, thereby avoiding damage to the upper cabin components. Since it is easier to control the force when touching the leads with human hands than with clips, even if the tested leads are very thin, they are not easily damaged. On the whole, the measurement efficiency is greatly improved, and since the model main line is no longer occupied for a long time, the constraints on the assembly progress are avoided.
[0042] Preferably, if Figure 3 As shown, there are two first electrical contacts 111, which are respectively installed at the fingertips of the thumb cover and the index finger cover of the left hand glove 110. There are two second electrical contacts 121, which are respectively installed at the fingertips of the thumb cover and the index finger cover of the right hand glove 120. When measuring the internal resistance value of the thermal control element 200, as shown in FIG. Figure 1 As shown, the thumb and index finger of the left hand hold the lead at one end of the thermal control element 200, and the thumb and index finger of the right hand hold the lead at the other end of the thermal control element 200. When measuring the insulation resistance of the thermal control element 200, the thumb and index finger of the left hand hold the lead at one end of the thermal control element 200, and the index finger of the right hand presses on the insulating cabin. In this way, it is more conducive to controlling the force when contacting the lead to avoid damage to the lead. At the same time, good electrical contact is guaranteed.
[0043] Specifically, in the example, Figure 1 , Figure 2 and Figure 3As shown, the first connector 150 includes a first electrode female buckle 151 and a first electrode male buckle 152. The first electrode female buckle 151 is connected to the positive pole of the multimeter 140 through a lead wire. The first electrode male buckle 152 is fixedly installed on the back of the left-hand glove 110, and is connected to the first electrical contact 111 installed on the palm surface of the left-hand glove 110 through a lead wire covered with an insulating shell. The first electrode female buckle 151 and the first electrode male buckle 152 can be connected or disconnected to connect or disconnect the positive pole of the multimeter 140 with the first electrical contact 111. The snap button form is adopted to facilitate the electrical assembly and disassembly of the multimeter 140 and the left-hand glove 110. The second connector 160 includes a second electrode female buckle 161 and a second electrode male buckle 162. The second electrode female buckle 161 can be connected or disconnected with the negative pole of the multimeter 140. The second electrode male buckle 162 is fixedly mounted on the back of the right hand glove 120, and is connected to the second electrical contact 121 mounted on the palm surface of the right hand glove 120 through a lead wire covered with an insulating shell.

In this way, it is convenient to connect and disconnect the extended test line 170 with the multimeter 140. The extended test line 170 can be connected or disconnected with the second electrical contact 121 through the second electrode female buckle 161. During the use of the extended test line 170, it passes through the left arm sleeve, the chest and the right arm sleeve in turn to avoid the extended test line 170 from hooking with the upper cabin component, thereby avoiding damage to the upper cabin component.
