Description

本实用新型是一种改进的插片式保险丝装置，它可在保险丝本体发生熔断时，自动给出熔断显示，具体地说，可自动发出亮光显示。The utility model is an improved plug-in type fuse device, which can automatically display a fuse display when the fuse body is blown, specifically, can automatically emit a bright light display.

现有的插片式或类似形式的保险丝装置，如图4所示：其构成只是在第一、第二两插片11、12之间设置一保险丝本体13而已，因此，当工作中不巧其保险丝熔断时，没有任何措施发出已熔断的指示。而在实际应用中，一般汽车或其他电气设备的配电盘上，往往设置有十几个以上的插片式保险丝装置，为了确知是哪个保险丝发生熔断，即使是专业技术人员，也只能对众多保险丝装置进行逐一检测，耗时费事，所以已有的这种保险丝装置在使用上极为不便，尤其是对于普通的电气设备使用者或汽车驾驶人员来说，在发生这种情况时更容易束手无策，至少会带来很大困扰。鉴于已有技术的上述缺点，本实用新型提出一种便于使用的改良式插片型保险丝装置。Existing blade-type or similar fuse device, as shown in Figure 4: its composition is only a fuse body 13 is set between the first and second two blades 11,12, therefore, when the work unfortunately When its fuse blows, there is nothing to indicate that it has blown. However, in practical applications, more than a dozen plug-in fuse devices are often arranged on the switchboard of general automobiles or other electrical equipment. It is time-consuming and troublesome to detect the fuse devices one by one, so the existing fuse devices are extremely inconvenient to use, especially for ordinary electrical equipment users or car drivers, it is easier to be at a loss when this happens, At least it will cause a lot of trouble. In view of the above-mentioned shortcomings of the prior art, the utility model proposes an improved plug-in type fuse device that is easy to use.

本实用新型的目的是提供一种使用便利的改良插片式保险丝装置，它可在使用过程发生保险丝熔断的情况时，自动发出亮光显示，从而可以立即得知是某一部位或一设备专用的插片式保险丝本体已熔断损坏，随即可以准确地更换新保险丝，而不需耗时费力地逐一检测每个保险丝装置。The purpose of this utility model is to provide an improved plug-in type fuse device that is convenient to use, which can automatically emit bright light when the fuse is blown during use, so that it can be immediately known that it is dedicated to a certain part or a device The blade fuse body has been blown and damaged, and the new fuse can be replaced accurately without the need for time-consuming and laborious testing of each fuse unit one by one.

如图1所示，本实用新型用于汽车或其他类似电气设备上的插片式保险丝装置1，主要的改进之处，是在插片式保险丝主座10内的第一、第二两插片11、12之间的上部，装设一上原保险丝本体13并联的发光二极管14或灯泡14’（如图3所示）作为熔断发光显示元件。如果此保险丝装置，采用并联的灯泡14’，用于汽车上时，如图3所示，应该与汽车电瓶的电压（一般为12V）相适应，根据电路的额定功率而选用高欧姆数的高阻抗灯泡，使其在原保险丝本体13未熔断之前，因高阻抗的作用，而不致自由发亮。同理，用于其他电器上时，也应作同样的考虑。如果并联的显示元件采用发光二极管14时，则该发光二极管14是由两只发光二极管14a、14b以相反方向并联而成一整体（如图2所示），这样，在使用上就不具方向性，可以和现有的插片式保险丝装置（图4所示）一样，随意插装使用。同时，在该二单元发光二极管14a、14b组成的发光显示二极管上，还应串联一阻抗电阻15，以使之与汽车或其他类似电气设备的电压相适应，使二极管不致被烧毁损坏。图2、图3中的部件3，表示上述保险丝装置所用之处的电器，如音响装置、马达、喇叭、灯泡等。As shown in Fig. 1, the utility model is used in a plug-in type fuse device 1 on automobiles or other similar electrical equipment. On the top between the sheets 11 and 12, a light-emitting diode 14 or a light bulb 14' (as shown in FIG. 3 ) connected in parallel with a Uehara fuse body 13 is installed as a fuse light-emitting display element. If this fuse device adopts parallel bulbs 14', when it is used in a car, as shown in Figure 3, it should be compatible with the voltage of the car battery (generally 12V), and a high ohm number should be selected according to the rated power of the circuit. Impedance bulb, before the original fuse body 13 is not fused, because of the effect of high impedance, can not be free to shine. In the same way, the same consideration should be made when it is used in other electrical appliances. If the display elements in parallel use light emitting diodes 14, then the light emitting diodes 14 are formed by two light emitting diodes 14a, 14b connected in parallel in opposite directions to form a whole (as shown in Figure 2), so that there is no directionality in use, Like the existing blade-type fuse device (shown in Figure 4), it can be plugged and used at will. Simultaneously, on the light-emitting display diode that this two unit light-emitting diodes 14a, 14b form, also should connect an impedance resistance 15, make it adapt to the voltage of automobile or other similar electric equipments, make the diode unlikely be burned damage. Component 3 in Fig. 2 and Fig. 3 represents electrical appliances where the fuse device is used, such as audio devices, motors, speakers, light bulbs, etc.

另外，本实用新型的插片式保险丝1在装设两并联的发光二极管14a、14b时，可以将整体的二单元发光二极管14a、14b连同阻抗电阻15一起直接模制在主座10之上；还可以先将二单元发光二极管14a、14b与阻抗电阻15模制成单一发光二极管元件14（如图1所示），再连同第一插片11、第二插片12一起插装固定于主座10上。In addition, when the blade fuse 1 of the present invention is equipped with two parallel light-emitting diodes 14a, 14b, the integral two-unit light-emitting diodes 14a, 14b together with the impedance resistor 15 can be directly molded on the main base 10; It is also possible to first mold the two-unit light-emitting diodes 14a, 14b and the impedance resistor 15 into a single light-emitting diode element 14 (as shown in Figure 1), and then insert and fix it together with the first insert 11 and the second insert 12 on the main body Seat 10.

由上述可知，由于本实用新型的用于汽车或类似电气设备上的插片式保险丝装置，因具有发光二极管14或灯泡14’作为保险丝熔断显示元件，所以在使用中若保险丝本体发生熔断，会自动发亮指示，用以表示该片插片式保险丝业已超负荷熔断，从而确定该片必须更换，因此不需要逐一检测其他插片式保险丝装置，使用上极为便利实用。而且，本实用新型的改良型插片式保险式装置在插入与拔出的使用操作上，完一与现有插片式保险丝一样，不影响原使用人员的使用习惯，便于使用。As can be seen from the above, because the blade type fuse device used in automobiles or similar electrical equipment of the present utility model has a light emitting diode 14 or a bulb 14' as a fuse blown display element, if the fuse body is blown during use, it will The automatic lighting indicator is used to indicate that the blade fuse has been overloaded and blown, so as to determine that the blade must be replaced, so there is no need to check other blade fuse devices one by one, which is very convenient and practical to use. Moreover, the improved plug-in type safety device of the utility model is completely the same as the existing plug-in type fuse in the use operation of inserting and pulling out, does not affect the use habits of the original users, and is easy to use.
