Description
One, technical field: the utility model relates to a kind of jointing device of electric parameter measurement, particularly relates to a kind of conversion connector that has fusing safety.
Two, background technology: well-known, on modern communication, network and various propulsion system such as locomotive, naval vessel, tank, in the reserve energy of battlebus, all have accumulator or battery pack, its internal resistance is very little, be generally several milliohms, promptly 0.001 ohmage magnitude can not adopt common multimeter directly to measure, and can not use general measurement mark pen or chuck, because of its contact resistance often greater than accumulator internal resistance, thereby the accuracy that influence is measured.In order to guarantee the measuring accuracy of accumulator internal resistance, the technician finds out employing 4 line system measuring methods, effectively eliminates the adverse effect that lead resistance and joint contact resistance bring the vehicle battery internal resistance measurement.The principle that 4 line systems are measured is still according to Ohm law formula: R=V/I, and physical circuit comprises an infusion circuit and a measurement loop, injects a steady current I at infusion circuit
z, measure the pressure drop V of electric current I z on accumulator internal resistance by measuring the loop
r, can calculate internal resistance r by Ohm law.
Referring to Figure of description, Figure 14: four-wire system accumulator internal resistance metering circuit schematic diagram, r is the internal resistance of tested accumulator among the figure, also has accumulator electromotive force E in this circuit simultaneously, generally represents the summation of various additional resistances such as slotted line resistance and contact resistance on each branch road with R.R is distributed in infusion circuit and measures in the loop, and 4 R among the figure are generally unequal, uncertain.But as long as keep injection current I
zInvariable (I
zBe designed to constant current source), then the existence of two R in the infusion circuit does not influence current precision, and voltage table is the high resistant instrument, and it is minimum to measure electric current, and the existence of measuring two R in the loop does not influence the voltage measurement precision yet, thereby has guaranteed the measuring accuracy of r.
The essence of 4 line system measuring methods is that the voltage that the measurement steady current produces on r-E branch road between two convergence points utilizes Ohm law to obtain r then.Here two keys that the meeting node is a problem, any additional resistance therebetween all influences measuring accuracy, it is that convergence point is forward as much as possible that additional resistance is reduced to the effective ways that can ignore degree, and this i.e. measurement of 4 line systems can not be reduced to the reason place of multimeter two-wire system.In the accumulator internal resistance measuring process, often adopt the low-resistance compressing piece at present, reduce damping contact pin with bolt and be fastened on the battery post, reach the purpose of eliminating contact resistance, need frequent dismounting, labour intensity is big, and efficient is low, and the crimping consistance is poor.The patent No. is a kind of accumulator internal resistance measurement conversion connector of 03245618.2, contain the low-resistance compressing piece, on each pole of single accumulator or battery pack, give dress low-resistance compressing piece with fastener, at two pin plugs or the two pin hole sockets of the terminal fixedly connected umbilical connector of each low-resistance compressing piece, short circuit connects between described two pin plugs or the two pin hole sockets.It is simple in structure that accumulator internal resistance is measured conversion connector, cost is low, can disposablely give being contained on each pole of accumulator, reduce internal resistance measurement labour intensity greatly, but because two syringe needles or pin hole socket directly are connected with the low-resistance compressing piece, there is not locking device, because accumulator internal resistance is extremely low, any short-circuit between conductors all can produce very big short-circuit current, is easy to burn slotted line or checkout equipment, even cause accumulator or battery pack to damage, there is potential safety hazard.
Three, utility model content:
The purpose of this utility model:, design a kind of conversion connector that has fusing safety at the problem that background technology exists.
The technical scheme that the utility model adopted: a kind of conversion connector that has fusing safety, contain the low-resistance compressing piece, fuse, one end of this conversion connector gives dress low-resistance compressing piece with fastener, the other end is the umbilical connector that has two syringe needles or two pin holes, be connected with two fuses respectively between two syringe needles of low-resistance compressing piece and umbilical connector or the two pin hole sockets, described two fuse one terminal shortcircuits are connected on the low-resistance compressing piece.
Described conversion connector; fuse is fixed on the back up pad; be connected with two syringe needles or the two pin hole sockets of low damping brace and umbilical connector respectively again; perhaps fuse is installed in the protection tube that plastic tube or other materials make, and is connected with two syringe needles or the two pin hole sockets of low-resistance compressing piece and umbilical connector respectively by lead again.
Described conversion connector, back up pad are printed circuit board, or are general rigid insulation plate.
Described conversion connector, two fuses are parallel to be fixed on the back up pad, or forms an angle respectively and be fixed on the back up pad, or is separately fixed on two back up pads, or is separately fixed on two support bars.
Described conversion connector, two fuses are parallel to be installed in the protection tube that plastic tube or other materials make, and perhaps two fuses are installed in respectively in the protection tube that two plastic tubes or other materials make.
Useful good effect of the present utility model:
1. have the conversion connector of fusing safety, simple in structure, cost is low, and high safety can prevent to cause because of short-circuit current is excessive the damage of measuring equipment or accumulator and battery pack, is easy to promotion and implementation.
2. this conversion connector is very easy to use, quick, satisfy the 4-2 line conversion of 4 line system measurement requirement simultaneously, can effectively eliminate the influence that contact resistance is measured accumulator internal resistance, simplified operation steps, shorten the accumulator internal resistance Measuring Time greatly, significantly improve work efficiency and measuring accuracy.
