汉英对照:
Chinese-English Translation:

2芯是走模拟电话信号(即是现在市话使用模式),4芯是走数字电话信号;4芯电话线,多用于现在办公系统线路布线使用:就像网线一样八芯 ,实际用四芯,备用2芯;四芯电话线也是一样的道理,用2芯备用2芯。

2-core is to use analog telephone signal (that is, the use mode of current local telephone), 4-core is to use digital telephone signal; 4-core telephone line is mostly used for office system line wiring: just like the network cable, 8-core is used, 4-core is used, 2-core is used; 4-core telephone line is the same principle, 2-core is used, 2-core is used.

电话线常见规格有二芯和四芯,线径分别有 0.4 和 0.5,若干地区有 0.8 和 1.0。除了二芯和四芯之外,还有四、六、八、十芯。从电话、宽带使用方面考虑,4 芯用得较多。

The common specifications of telephone lines are two core and four core, with diameters of 0.4 and 0.5 respectively, and 0.8 and 1.0 in some areas. In addition to two and four cores, there are four, six, eight and ten cores. Considering the use of telephone and broadband, 4-core is used more.

四芯的线路,可以用模拟电话机,但数字机,必须是四芯的。四芯电话线,不只是和二芯电话线少二芯而已,它们在应用上是有区别的,如果只是普通的电话机,普通的模拟电话,二芯是没得问题的,但是如果是数字电话机则必须是四芯电话机;而且四芯线,必须是按照固定的顺序来连接才可以的;也就是讲四芯的,可以当二芯使用,但是如果是二芯线,用在数字电话机上,则会没得声音,根本无法工作的。摘机会没有声音的。

Four core line, can use analog telephone, but digital machine, must be four core. Four core telephone lines are different from two core telephone lines in application. If they are only ordinary telephones and ordinary analog telephones, two core telephone lines are OK. But if they are digital telephones, they must be four core telephones. Moreover, four core telephone lines must be connected in a fixed order. In other words, four core telephone lines can be used as four core telephone lines Two core is used, but if it is a two core cable, it will not work if it is used in a digital telephone. There is no sound.

2 芯是走模拟电话信号(即是现在市话使用模式),4 芯是走数字电话信号;家里装潢布线一般是排 2 条网线,一条网络一条电话(费用相差的不多)。通电话传输只需要 2 条电话线,也就是中间 2 芯,按标准接线顺序,通常使用红色和绿色的作为。电话传输,黄色和黑色用于反极传输。

2-core is to take analog telephone signal (that is, the current mode of local telephone use), 4-core is to take digital telephone signal; home decoration wiring is generally arranged with 2 network cables, one network and one telephone (the cost difference is not much). Only two telephone lines are needed for telephone transmission, that is, two cores in the middle. According to the standard wiring sequence, the red and green ones are usually used. Telephone transmission, yellow and black for reverse transmission.

4 芯电话线,多用于现在办公系统线路布线使用:就像网线一样八芯 ,实际用四芯,备用 2 芯;四芯电话线也是一样的道理,用 2 芯备用 2 芯。在现代办公通信中,很多进口通信终端都是 4 芯电话线,只有在综合布线时,考虑用户 2-5 年的发展情况来布线,才能解决用户的实际需求。

The 4-core telephone line is mostly used for office system wiring: just like the network line, the 8-core telephone line is actually used with 4-core and standby with 2-core; the 4-core telephone line is also used with 2-core and standby with 2-core. In modern office communication, many imported communication terminals are 4-core telephone lines. Only when considering the development of users in 2-5 years, can the actual needs of users be solved.

电话线两芯和四芯的区别

The difference between two core and four core telephone lines

电话线一般分为 2 芯,4 芯,(4 芯适用于公司或部分集团电话使用),6 芯(6 芯适用于数字电话使用)。两芯标准的电话水晶头是 RJ32。分别称为 A 线、B 线,没有正负极的区别。

Telephone lines are generally divided into 2-core, 4-core (4-core is suitable for company or part of group telephone) and 6-core (6-core is suitable for digital telephone). The two core standard telephone crystal head is rj32. They are called a line and B line respectively, and there is no difference between positive and negative poles.

至于听筒的四芯线,通过一个线圈或者集成电路出来之后,到听筒就需要四根线,两根由 MIC 用,另外两根受话器用。一般买两芯的双绞线,有条件的可以考虑上 4 芯。

As for the four core wire of the handset, after it comes out through a coil or integrated circuit, it needs four wires to reach the handset. Two wires are used by mic and the other two wires are used by receiver. Generally buy two core twisted pair, conditional can consider on 4 core.

2 芯是走模拟电话信号(即是现在市话使用模式),4 芯是走数字电话信号;家里装潢布线一般是排 2 条网线,一条网络一条电话(费用相差的不多)。通电话传输只需要 2 条电话线,也就是中间 2 芯,按标准接线顺序,通常使用红色和绿色的作为。电话传输,黄色和黑色用于反极传输。

The four core telephone line is mostly used for office system wiring: just like the network line, eight cores are used, four cores are used in practice, and two cores are reserved; the same is true for the four core telephone line, two cores are used, and two cores are reserved. In modern office communication, many imported communication terminals are 4-core telephone lines. Only when considering the development of users in 2-5 years, can the actual needs of users be solved.

电话线水晶头接法/电话线接法

Connection of telephone line with crystal head

电话线水晶头接法 两种方法:1.A 头:黑,绿,红,黄;B 头:黑,绿,红,黄。2.A 头:黑,绿,红,黄;B 头:黄,红,绿,黑。两种接法都可以,电话线的两根线是交流的,电话里面有整流器,也就是说不管这两根线你怎么接,电话都会自动整流成直流。如果是 4 根的就 1 组 1 对 4 芯的话:中国制式的是用 23,也就是中间两根网线接 1236 电话线是 45。

There are two ways to connect the crystal head of telephone line: 1. Head a: black, green, red and yellow; head B: black, green, red and yellow. 2. Head a: black, green, red, yellow; head B: yellow, red, green, black. Both methods are OK. The two lines of the telephone line are AC, and there is a rectifier in the telephone. That is to say, no matter how you connect the two lines, the telephone will automatically be rectified into DC. If it’s a group of four, one pair of four cores: the Chinese standard uses 23, that is, the middle two network cables connect to 1236, and the telephone line is 45.

二芯电话线水晶头接法 将两芯电话线的一端口,剥开最外层绝缘层约 0.5 厘米,露出两根细的电话线内芯,请不要去除内芯上的绝缘层,将内芯插入到两芯水晶头中间的两个槽位,然后将卡线钳套入,并上下夹紧,这时两根内芯线,应该已经与水晶头内部的两根金属片子完全连接在一起。二芯电话线连接时可以不分顺序,只要是通的就可以了四芯专用话机电话线必须按顺序来连接。

Two core telephone line crystal head connection method: peel off the outermost insulating layer of one end of two core telephone line about 0.5cm to expose two thin inner cores of telephone line. Please do not remove the insulating layer on the inner core, Insert the inner core into the two slots in the middle of the two crystal heads, then insert the clamp clamp and clamp it up and down. At this time, the two inner core wires should have been completely connected with the two metal pieces inside the crystal head. Two core telephone lines can be connected in any order as long as they are connected. Four core telephone lines must be connected in order.

四芯电话线水晶头接法 电话线水晶头接法四条内芯在水晶头内的排列顺序(可通过色彩来分辨)在两真个接法上恰好相反,好比两水晶头背对着自己,在第一个水晶头上的内芯排列顺序是从上到下为黄/绿/红/黑,则在第二个水晶头上应该是从上到下黄/绿/红/黑。 四芯线顺序: 黑、红、绿、黄 两端是直线连接方式。中间两根为信号线,两边的为数据线。

The arrangement order of the four inner cores in the crystal head (which can be distinguished by color) is just the opposite in the two connection methods. For example, the two crystal heads are facing away from themselves. The arrangement order of the inner cores on the first crystal head is yellow / Green / red / black from top to bottom, while that on the second crystal head should be yellow / Green / red / black from top to bottom. Four core wire sequence: black, red, green, yellow, both ends are linear connection. The middle two are signal lines and the two sides are data lines.

大对数电缆:大对数线缆的施工首先要知道主色和副色(白、红、黑、黄、紫;蓝、橙、绿、棕、灰),然后按顺序打线就行了。100 对缆分四扎,每扎里应该都有以白、红、黑、黄、紫为主的线对,具体可以这样分:白蓝、白橙、白绿、白棕、白灰(这是第一组一般先打这几对线)接着是红蓝、红橙、红绿、红棕、红灰;再接着是用的 110 的配线架,电话打线以后接电话模块的 2/3 就对了。

Large logarithmic cable: the construction of large logarithmic cable should first know the main color and secondary color (white, red, black, yellow, purple; blue, orange, green, brown, gray), and then wire in sequence. 100 pairs of cables are divided into four bundles, each bundle should have white, red, black, yellow and purple pairs, which can be divided as follows: white blue, white orange, white green, white brown and white gray (this is the first group to play these pairs of cables first), then red blue, red orange, red green, red brown and red gray; then the 110 distribution frame is used, and the two thirds of the telephone module is right after the telephone is wired.
