Description

Power indicator light, power indicator module and power distribution unit

technical field

The invention relates to power distribution technology, more specifically, the invention relates to a pluggable power indicator light, a power indicator module and a power distribution unit using the power indicator light.

Background technique

The power indicator lights of general electrical products work intermittently. However, the power indicator light applied to the power distribution unit (PDU: power distribution unit) is a long-term, continuous, non-intermittent power-on and working power indicator light, and its technical performance indicators and safety test requirements are more stringent and demanding , because PDU products are usually special safety products used in data center computer rooms to provide power distribution and connection for various electronic and electrical equipment in the cabinet.

As an electrical product, absolute fault-free is unscientific and does not exist. Although the power indicators of PDU products have very high reliability, there are still some phenomena and possibilities of failure and damage. Once the power indicator light of the PDU product fails or is damaged and cannot be displayed normally, although the power output of the PDU will not be affected, the power indicator function will be lost, and the result of visual inspection is a failure. Because the power indicator lights on the existing PDU products are fixed inside the PDU, if you want to repair the power indicator light, you must first cut off the power, and then remove the LED indicator light from the PDU. Replace with new indicator light. Obviously, the equipment in the data center computer room cannot be powered off at will, so the repair and replacement of the power indicator lights on the existing PDU products are very inconvenient, and it will also affect the continuous operation of the electrical equipment.

The other side of the upper housing 41 is provided with a mounting hole 45 for installing the overload protection module 50, and an oblique notch 46 is provided on the upper surface of the upper housing 41 along the upper edge of the mounting hole 45, so that the overload protection module 50 out of the mounting hole.

Specifically as shown in Figure 7, the barrel 43 includes a barrel wall 431 and a barrel bottom 432 extending downward from the upper surface of the upper casing 41, and a protrusion 433 is formed on the inner side of the barrel wall 431, and the protrusion 433 is located on the barrel wall. 431 at the position corresponding to the buckle protrusion 113 on the shell of the power indicator light 100 . When the power indicator light 100 is put into the barrel 43 , the buckle protrusion 113 is locked with the protrusion 433 on the barrel wall 431 , thereby fixing the power indicator light 100 in the barrel 43 . The two pins 34 and 35 of the power indicator light 100 pass through the two through holes 434 provided on the barrel bottom 432 of the barrel 43, and then respectively connect with the power pins 80 and 70 positioned at the bottom of the lower housing 42. . The specific structure and electrical connection of the power pins 80 and 70 will be described in detail later. When the power indicator lamp 100 needs to be repaired or replaced, it is only necessary to apply a certain upward force to the oblique cutout 131 on the power indicator lamp housing from the oblique cutout 46 on the upper housing 41 (see FIG. 8 ) , the buckle protrusion 113 can be released from the protrusion 433 on the barrel 43, so that the power indicator light can be taken out.

Referring again to FIG. 6 and FIG. 7 , the overload protection module 50 includes a bracket 51 and a fuse 52 installed at the lower part of the bracket 51 . The bracket 51 is installed in the mounting hole 45 formed on the upper housing 41, and a guide block 53 is formed on one side of the bracket 51, which cooperates with the guide groove 47 formed on the mounting hole 45, so that the bracket 51 can be mounted from the mounting hole 45. Slide in and out of the case. Moreover, the lower end of the guide block 53 is formed with a limit block (not shown) whose width is larger than that of the guide groove 47, so as to ensure that the bracket 51 will not fall off. In addition, an oblique cut 46 is formed on the other side of the installation hole 45 opposite to the guide groove 47 for pulling out the bracket 51 . The fuse 52 can be, for example, a fuse with a glass or ceramic shell, and its two ends are respectively plugged into the power pins 60 and 70 located at the bottom of the lower housing 42 .

As shown in Figure 7, the power supply pin 60 includes a horizontal support 62 positioned at the bottom of the lower housing, a terminal 61 extending downward from the side of the horizontal support 62 and extending out of the lower housing, and a connecting terminal 61 extending from the side of the horizontal support 62. Two clips 63 protrude upward from the upper surface, and the two clips 63 are oppositely arranged to form an elastic clip for clamping one end of the fuse 52 to form an electrical connection. Similarly, the power pin 70 has a structure similar to that of the power pin 60, which includes a horizontal support 72 positioned at the bottom of the lower housing, a terminal 71 extending downward from the side of the horizontal support 72 and extending out of the lower housing, and Two clamping pieces 73 protrude upward from the upper surface of the horizontal support 72 , and the two clamping pieces 73 are arranged oppositely to form elastic clips for clamping the other end of the fuse 52 to form an electrical connection. Through such a structural design, the fuse 52 installed on the lower part of the bracket 51 can be positioned and electrically connected by the clamping of the two power supply pins 60 and 70, and when the fuse fails or is damaged and needs to be repaired or replaced, it can be opened from the oblique cutout 46. Apply a certain upward force to the bracket 51, and the fuse 52 can be driven by the bracket 51 to break away from the clamping of the two power supply pins 60 and 70, and pulled out from the mounting hole 45, so that the fuse can be removed for replacement. On the contrary, push the bracket 51 and the fuse 52 along the installation hole 45, so that the two ends of the fuse 52 are inserted into the two clips of the power pins 60 and 70, so as to position and form an electrical connection.

In addition, as shown in FIG. 7 , on the side of the horizontal support 72 of the power supply pin 70 opposite to the connection terminal, a downwardly bent folding ear 74 is punched out, and the folding ear 74 corresponds to the protruding pin 35 of the power indicator light 100 , so that the pin 35 is inserted into the horizontal support 72 and abuts against the folding ear 74 to form an electrical contact. Similarly, the power supply pin 80 includes a horizontal support 82 positioned at the bottom of the lower housing, a terminal 81 extending downward from one side of the horizontal support 82 and extending out of the lower housing, and punched on the other side of the horizontal support 82. A folded ear 83 bent downward is formed, and the folded ear 83 corresponds to the protruding pin 34 of the power indicator light 100 , so that the pin 34 is inserted into the horizontal support 82 and abuts against the folded ear 83 to form an electrical contact.
