Selection and application range of dc socket

The dc socket is one of the very wide range of electronic components used in our daily lives. Its models and specifications are diverse and are mainly divided into two types of packages. One is SMT chip package and the other is DIP plug-in package. Conventional DC socket center pins are 0.5mm, 0.7mm, 1.0mm, 1.1mm, 1.3mm, 1.65mm, 2.0mm, 2.5mm, 3.0mm, etc., and can also be divided into 2.0dc socket, 2.5dc socket, 3.0dc socket Wait. Faced with products with many models and specifications, are you very distressed about the selection of dc sockets? If you are not familiar with the product, the selection of dc sockets will be more difficult. At this time, I suggest that you can consult relevant technical personnel . Usually when we replace dc sockets, we should try our best to choose products of the same specifications and models to avoid inapplicability. Let me briefly introduce you to the application of dc sockets and related product knowledge!

　　 One. The application range of dc socket is:

　　(1) Household appliances: induction cooker, rice cooker, electric fan, television, computer, microwave oven, etc.

　　 (2) Digital products: digital cameras, digital video cameras, etc.

　　(3) Audio-visual products: MP3, MP4, DVD, audio, etc.

　　(4) Medical equipment: sphygmomanometer, clinical thermometer, hospital call system, etc.

　　(5) Security products: video intercoms, monitors, etc.

　　(6) Fitness equipment: running machine, massage chair, etc.

　　 2. The structure of the dc socket:

　　Dc socket is mainly composed of fork-shaped contact shrapnel, longitudinal socket directional keyway, insulating base, horizontal socket, etc. Two fork-shaped contact shrapnels are positioned at the center of the base, arranged in vertical and horizontal directions and are not connected to each other. One end of the fork-shaped contact spring is a wiring port. The top surface of the base cylinder of the socket is used to connect the input power cord. One end of the fork-shaped contact spring of the dc socket is composed of two elastic arms interconnected by the base.

　　 Three. Purchase and use of dc socket:

(1) First of all, when we select the dc socket, we must check whether the flame retardant level of the dc socket material is up to the standard. If the material of the socket is not flame-retardant, it will cause heat accumulation when it encounters a short circuit or overcurrent during use. Cause a fire. Secondly, it is recommended not to buy some porous dc sockets, because these porous sockets have very strict requirements for work. If there is a mistake or misuse, it is very likely that accidents such as electric shock will occur during use, so choose the porous socket It must be carefully considered.

　　(2) When purchasing a dc socket, we usually pay attention to whether the rated voltage and rated current of the product are up to standard. If these parameters of the dc socket are not up to standard, the power of the electrical equipment will be too large or the load capacity of the power cord will be insufficient, resulting in heat buildup and fire. Therefore, when purchasing, pay attention to whether the rated current of the dc socket meets the standard.

　　(3) The plug and converter terminal of the rewirable dc socket must be screw clamp type terminals. The purpose of this is to prevent the power cord from being pulled out by accidental pulling. Only by forming an integral non-rewirable plug can the socket be allowed to be welded. Nowadays, the plug type of the dc socket is mostly flat, and the two poles of the socket are grounded, which is also called a three-pole plug. If it is a cylindrical plug of a dc socket, it is recommended that you do not choose it. This product does not meet the use standard.

The above is the introduction about the selection, structure, purchase and precautions of dc socket! Commonly used models on the market are: dc socket DC-005, DC-050, DC-044E, DC-022B, DC-025W , DC-005C, DC-062, DC-062, DC-008, DC-005D, DC-008, etc. If you don't understand anything about the selection of dc sockets, I suggest you communicate with our customer service staff in time to avoid unnecessary losses due to improper selection.
