Adjustable length power cord fixing buckle

The invention relates to an adjustable length power cord fixing buckle, in particular to a rigid connection with another electrical connection end by the external structure of the buckle power supply line.

Since the power has been widely spread through the application of transmission and distribution systems, the extension of the power line configuration has not been cut with our modern life, and the power will be extended by the efficient branch of the power line. The most effective way is to set the power supply at the terminal of the power line. The connector or the charging base provides the convenience of connecting power at any time by the connection structure of the power connector and the power receiving base, and the applications of the power connector and the power socket commonly used in daily life are, for example, plugs and sockets.

Conventional power connector and the application of the power socket, the common way is to align the two male and female seats with each other and apply the force of the pressing force, so that the male seat and the female seat can be connected by the plug and the connection can be completed. The pull-out action can easily achieve the purpose of power-on. However, although the method of plugging and unplugging the power connector and the power-on socket is convenient, the simple operation method also causes danger and inconvenience in use, for example. When the child is in a child's condition, the power cord is easily pulled by the young child, which may cause the power connector to be disconnected from the power supply seat and cause electric shock or sparking danger. In addition, in the case where the power cannot be interrupted, such as the hospital's life. In the case of machines, computer servers, defense computer equipment, ground or air transportation systems, if the power connector and the power supply stand off due to accidental force, the machine may not operate due to power interruption, which may cause unpredictable In view of this, in order to firmly connect the power cord power connector and the power socket, a power cord fixing buckle has been developed.

The conventional power cord fixing buckle has been widely used in the industry, such as the "Power Line Positioning Structure" of the Republic of China Patent No. 557096, and the "Clamping Frame for the Plug-in Power Input Block" of the Republic of China Patent Bulletin No. I232617 As shown in the figure, the application can be roughly divided into two types, one is for the power connector and the power connector docking, as shown in Figure 1, is a schematic diagram of the conventional power cord docking via the power connector, one of the power cord 10a and the other Two power cords 10b docked The power cable 10a is provided with a positioning portion 13 , and the connecting portion 21 of the fixing buckle 20 is connected to the positioning portion 13 , and a locking portion 22 is extended from the connecting portion 21 . After the power cord 10a is inserted into the power cord 10b, the latching portion 12 of the power cord 10b is fastened by the latching portion 22 of the securing buckle 20, wherein the clamping portion 12 is the power cord. The difference between the step 10b and the power connector 14 is that the power cord 10a can be firmly engaged with the power cord 10b by the snapping manner of the fixing buckle 20 without being accidentally pulled. The power cord 10a is detached from the power cord 10b.

Furthermore, another conventional power cord fixing buckle is used for the power connector and the power socket, as shown in FIG. 2, which is a schematic diagram of the docking of the power cord through the power connector and the power socket, wherein one power cord The front end of the 10 is provided with a power connector 14 , and the power connector 11 that is connected to the power connector 14 is provided with a positioning portion 13 . The connecting portion 21 of the fixing button 20 is connected to the positioning portion 13 , and the connecting portion 21 extends from the connecting portion 21 . After the power connector 14 is inserted into the power connector 14 , the latching portion 22 of the power cord 10 is fastened to the clamping portion 12 of the power cord 10 , wherein the clamping portion 12 is It is a recess on the power cord 10, and the conventional structure can be used to securely connect the power cord 10 to the power receiving base 11 by the snapping manner of the fixing buckle 20, without causing accidental pulling. The power cord 10 is easily detached from the power receiving base 11.

In summary, the conventional power cord fixing buckle can be applied to most power cord connection occasions. However, the application of the conventional power cord fixing buckle has a limitation of compatibility due to its structure, as in the foregoing conventional knowledge. Patent No. 557096 and No. I232617, wherein the fastening portion 22 of the fixing buckle 20 must correspond to the position of the clamping portion 12, which may be the practical application. The difference between the power cable 10 and the power connector 14 or the groove provided on the power cable 10, so that the length of the fixing buckle 20 is different, which results in the connection portion 21 to the buckle portion 22. The distance between the power cord 10 and the power connector 14 is limited, so that different length specifications are fixed. The buckle 20 can only correspond to the power connector 14 or the power cord 10 with the same physical specifications. It has become a long-term practice on the market, and the length of the fixing buckle 20 is numerous and inconsistent, resulting in the conventional power cord fixing buckle being unable to be fixed. Widely used in different specifications of power cords and power connectors, indirectly lost the intention to increase the fixed connection of the power cord, it is a shortcoming of the need to improve the fixed power cord fixed buckle.

The main purpose of the invention is to make up for the shortcomings of the conventional power cord fixing buckle structure, and to provide a wide range of power cord fixing buckles with different power cords and power connectors, and to increase the power cord fixing buckles. Application range.

In order to achieve the above object, the present invention utilizes a clamping portion of a fixed buckle to connect a power supply line to another power supply line or a power receiving base, and includes at least one of the power supply lines or the a fixing portion on the power receiving base, the fixing buckle has a connecting portion connected to the positioning portion, and the connecting portion extends a buckle portion fastened to the clamping portion, wherein the connecting portion and the card Between the buckle portions, at least one expansion member that changes the distance between the connection portion and the buckle portion is provided. The above is the basic structure of the present invention, wherein the extension member can be a spring member and the connection portion and the buckle portion The object is integrally formed, thereby achieving the purpose of changing the distance between the connecting portion and the hook portion.

According to the above technical solution, the length specification of the fixing buckle of the present invention can be adjusted according to different types of connection objects, and the distance between the connecting portion and the buckle portion is adjusted correspondingly, and the conventional method of fixing the buckle is achieved. Both the patent and the existing products can not be completed, so that the present invention can be applied to various connection objects of different specifications, so that the power cord fixing buckle can be widely used in various environments.
