技术领域technical field
本实用新型涉及一种插头或插座，尤其涉及插头输入插片或插座输出接触片耦合位置的一种保护装置。The utility model relates to a plug or a socket, in particular to a protection device for the coupling position of a plug input insertion piece or a socket output contact piece.
背景技术Background technique
在日常生活中，经常会使用到插座或插头，众所周知，插座和插头都是用来连接用电器，插座与插头接触的部件通常由插座内的铜合金构成，用铜合金制成可容纳插头输入插片的带有弹性的接触片，而插头和插座的外部壳体采用塑料来绝缘。一般来说，插座安装在墙壁上，插头部分用于电器，或者，插头后面带一个移动的多孔输出的插座。在长期使用中，常会发生插座内部接触片失去弹性从而不能与插头保持良好接触、长期受潮湿影响或使用时负载超过插座的额定电流值等情况，这样，铜合金片就会产生高温，如果高温过大，就会熔化插座的绝缘外壳进而引燃靠近插座的物质，从而引起火灾。同样，当插头的负载超过插座额定值时，插座的铜合金接触片会产生高温，此时插头火线L、零线N接触片也会产生高温，这样插头的绝缘外壳也会熔化，甚至引燃临近物质造成火灾，给人们带来人身伤害和财产损失。In daily life, sockets or plugs are often used. As we all know, sockets and plugs are used to connect electrical appliances. The parts in contact with the plug are usually made of copper alloy in the socket, which can accommodate the input of the plug. The inserts have elastic contact pieces, while the outer shells of the plugs and sockets are insulated with plastic. Generally speaking, the socket is installed on the wall, and the plug part is used for electrical appliances, or the socket with a movable multi-hole output behind the plug. In long-term use, it often happens that the internal contact piece of the socket loses its elasticity and cannot maintain good contact with the plug, is affected by humidity for a long time, or the load exceeds the rated current value of the socket during use, etc., so that the copper alloy sheet will generate high temperature. If the high temperature If it is too large, it will melt the insulating shell of the socket and ignite the material near the socket, causing a fire. Similarly, when the load of the plug exceeds the rated value of the socket, the copper alloy contact sheet of the socket will generate high temperature. At this time, the live wire L and the neutral wire N contact sheet of the plug will also generate high temperature, so that the insulating shell of the plug will also melt and even ignite. Adjacent substances cause fires, causing personal injury and property damage.

具体实施方式Detailed ways
为了更好地理解本实用新型的结构、功能和效果，现运用以下较佳实施例并结合附图进行详细说明。应当理解的是，示例的结构设计及以下描述本实用新型所结合的实施例并不旨在穷尽根据本实用新型的所有实施例。In order to better understand the structure, function and effect of the utility model, the following preferred embodiments are now used in detail with reference to the accompanying drawings. It should be understood that the exemplary structural designs and the following descriptions of the combined embodiments of the present invention are not intended to exhaust all embodiments according to the present invention.
首先参见图1A-1B、图3A-3B并结合图5，根据本实用新型的具有防火保护装置的插头可包括由上壳体1和下壳体2构成的绝缘壳体，控制电路板7放置于该绝缘壳体内并与相应控制机构电连接。复位按钮6突出于上壳体1外部并连接复位开关10(图5)以构成复位开关组件RESET。图释出的输入插片包括零线输入插片3、火线输入插片4，并且可选择地包括地线插片5。在图1A-1B示出的实施方式中，电连接至控制电路板7的热敏电阻9设置于零线输入插片3和火线输入插片4之间，以实时监测输入插片的温度并将温度信号传递给脱扣电路中。虽然在该实施方式中示出了位于输入插片之间的一个热敏电阻，但本领域技术人员应能理解的是，取决于实际需要，在输入插片的一个或多个侧面上设置一个或多个热敏电阻都是可能的。为了快速准确地监测输入插片的温度，可优选在热敏电阻9与零线输入插片3和火线输入插片4之间分别设置由导热材料制成的导温片8。然而，也可考虑将热敏电阻9直接设置为邻近输入插片。例如，如图3A-3B所示，提供两个热敏电阻9，从而省去了导温片的需要。First referring to Fig. 1A-1B, Fig. 3A-3B in combination with Fig. 5, the plug with fire protection device according to the utility model may include an insulating case composed of an upper case 1 and a lower case 2, and the control circuit board 7 is placed It is inside the insulating casing and is electrically connected with the corresponding control mechanism. The reset button 6 protrudes from the upper casing 1 and is connected with a reset switch 10 ( FIG. 5 ) to form a reset switch assembly RESET. The input inserts illustrated in the figure include a neutral line input insert 3 , a live line input insert 4 , and optionally include a ground line insert 5 . In the embodiment shown in FIGS. 1A-1B , the thermistor 9 electrically connected to the control circuit board 7 is arranged between the neutral line input insert 3 and the live line input insert 4 to monitor the temperature of the input insert in real time and Pass the temperature signal to the trip circuit. Although a thermistor located between the input tabs is shown in this embodiment, those skilled in the art should understand that, depending on actual needs, a thermistor is provided on one or more sides of the input tabs. or multiple thermistors are possible. In order to quickly and accurately monitor the temperature of the input inserts, it is preferable to arrange temperature conduction sheets 8 made of thermally conductive materials between the thermistor 9 and the neutral input inserts 3 and live line input inserts 4 . However, it is also conceivable to arrange the thermistor 9 directly adjacent to the input tab. For example, as shown in Figures 3A-3B, two thermistors 9 are provided, thereby eliminating the need for a thermal pad.
图2A-2B和图4A-4B示出了根据本实用新型的具有防火保护装置的插座。该插座同样由上壳体1和下壳体2构成绝缘壳体，并在其中设置与相应控制机构电连接的控制电路板7。输出接触片包括零线输出接触片30、火线输出接触片40，并可选择地包括地线接触片50。与上述插头的结构相似，在零线输出接触片30和火线输出接触片40之间设有热敏电阻9，并可根据实际需要在热敏电阻9与输出接触片之间提供导温片8(图2A-2B)或者不提供导温片(图4A-4B)。2A-2B and 4A-4B show a socket with a fire protection device according to the present invention. The socket is also composed of an upper shell 1 and a lower shell 2 to form an insulating shell, and a control circuit board 7 electrically connected to a corresponding control mechanism is arranged therein. The output contact pieces include a zero line output contact piece 30 , a live line output contact piece 40 , and optionally a ground line contact piece 50 . Similar to the structure of the above-mentioned plug, a thermistor 9 is provided between the zero line output contact piece 30 and the live line output contact piece 40, and a temperature conducting piece 8 can be provided between the thermistor 9 and the output contact piece according to actual needs (Figure 2A-2B) or not provide thermal pad (Figure 4A-4B).
在使用时，根据本实用新型的具有防火保护装置的插头或插座的原理相同，下面针对具有导温片的插座结合图5来详细描述温控监测过程。When in use, the principle of the plug or the socket with the fire protection device according to the present invention is the same, and the temperature control monitoring process will be described in detail below in conjunction with FIG. 5 for the socket with the heat conducting sheet.
正常使用情况下，插座的零线输出接触片3、火线输出接触片4的温度处于安全的温度范围内，导温片8的温度小于等于零线输出接触片3、火线输出接触片4的温度，因此热敏电阻9的温度小于预定温度值，阻值没有发生变化，热敏电阻9不会启动短路线圈SOL，线圈SOL没电插座可以继续使用。反之，当插座的零线输出接触片3和/或火线输出接触片4的温度高于安全温度范围时，导温片8的温度也会随之升高，进而热敏电阻9由于输出接触片的温度大于预定温度值而发生阻值的明显变化，短路线圈SOL得电，并切断复位开关10，从而断开了电路，使用户不能继续使用插座，只有将故障排除后，重新压下复位按钮6，才能继续使用。Under normal use, the temperature of the zero line output contact piece 3 and the live line output contact piece 4 of the socket is within a safe temperature range, and the temperature of the temperature conducting plate 8 is less than or equal to the temperature of the neutral line output contact piece 3 and the live line output contact piece 4. Therefore, the temperature of the thermistor 9 is less than the predetermined temperature value, and the resistance value does not change, the thermistor 9 will not start the short-circuit coil SOL, and the coil SOL can continue to be used without electricity. Conversely, when the temperature of the zero line output contact piece 3 and/or the live wire output contact piece 4 of the socket is higher than the safe temperature range, the temperature of the thermal conduction piece 8 will also increase thereupon, and then the thermistor 9 is due to the output contact piece If the temperature is higher than the predetermined temperature value and the resistance value changes significantly, the short-circuit coil SOL will be energized and the reset switch 10 will be cut off, thereby disconnecting the circuit, so that the user cannot continue to use the socket. Only after troubleshooting, press the reset button again 6, to continue to use.
本实用新型的技术内容及技术特点已揭示如上，然而本领域技术人员应能意识到的是，在本实用新型的创作思想下，可以对上述实施例进行各种结构性或逻辑性的变化和改进，但都属于本实用新型的保护范围。以上所描述的具体实施例并不旨在穷尽根据本实用新型的所有实施例。本实用新型的保护范围由权利要求所确定。The technical content and technical characteristics of the present utility model have been disclosed above, but those skilled in the art should be able to realize that, under the creative thinking of the present utility model, various structural or logical changes and modifications can be made to the above-mentioned embodiments. Improvements, but all belong to the protection scope of the present utility model. The specific embodiments described above are not intended to exhaust all embodiments according to the present invention. The protection scope of the utility model is determined by the claims.
