Phoenix connection terminal is made of two parts, one is to press the wire tightly, and then to the other part, which is welded to the PCB board. This is connected with the mechanical principle of the bottom, and the anti vibration design ensures the long-term air tight connection of the product and the service reliability of the finished product.

插座两端可加装配耳，装配耳在很大程度上可以保护接片并且可以防止接片排列位置不佳，接线端子同时这种插座设计可以保证插座可以正确的插进母体。

The two ends of the socket can be equipped with matching ears, which can protect the connector to a great extent and prevent the connector from being arranged in a bad position. At the same time, the wiring terminal can ensure that the socket can be inserted into the matrix correctly.

插座也可以有装配扣位和锁定扣位。装配扣位可以起到更加稳固地固定到PCB板上，锁定扣位可以在安装完成后锁定母体和插座。

The socket can also have assembly buckle and locking buckle. The assembly buckle can be more firmly fixed to the PCB board, and the locking buckle can lock the matrix and socket after the installation.

各种各样的插座设计可以搭配不同母体的插入方法，比如说：水平、垂直或倾斜向印刷电路板等，可以根据客户的要求选择不同的方式。既可以选择公制线规也可以选择标准线规，是市场上销量好的端子类型。

A variety of socket design can be combined with different matrix insertion methods, such as: horizontal, vertical or inclined to the printed circuit board, etc. different methods can be selected according to the requirements of customers. You can choose either metric wire gauge or standard wire gauge. It is a type of terminal with good sales in the market.

菲尼克斯接线端子箱内部设计安装有一个单相三孔220V，16A电源插座和一个维修照明灯，以方便用户在日常检查维护时使用。另外，电路中还设计安装有单极断路器开关，用来保护整个电路的安 全正常运行。同时还设计安装有转换开关，用户可根据现场实际运行情况需要，对箱体内加热器可任意转换手动、自动控制方式。

The internal design of Phoenix terminal box is equipped with a single-phase three hole 220V, 16a power socket and a maintenance lamp, so as to facilitate the use of users in daily inspection and maintenance. In addition, a single pole circuit breaker switch is designed and installed in the circuit to protect the safe and normal operation of the whole circuit. At the same time, a change-over switch is designed and installed, so that the user can change the manual and automatic control mode of the heater in the box according to the actual operation needs.
