Abstract
The utility model relates to a network terminal resistor module which consists of a resistor, a resistor connecting plug, a shell, connecting sheets and connecting bolts. The resistor and the resistor connecting plug are arranged in the shell; the resistor is communicated with the resistor connecting plug; the connecting sheets are arranged at the two ends of the shell; and the connecting sheets are provided with the connecting bolts. The network terminal resistor module has simple mounting, in-place plugging and reasonable and compact structure, does not generate short circuit and virtual connection phenomena and can ensure the normal running of network equipment.
Description
Technical field:
The utility model relates to a kind of network terminal resistive module, particularly a kind of DeviceNet network terminal resistive module.
Background technology:
In the network communication process, it is very little even do not have that signal runs into cable resistance suddenly in line end, and signal will cause reflection in this place.The principle of sort signal reflection enters another kind of medium to light from a kind of medium and will cause that reflection is similar.Eliminate the method for this reflection, just must make the impedance of cable continuous at terminal resistance onesize of terminal cross-over connection of cable with the characteristic impedance of cable.Because the transmission of signal on cable be two-way, therefore, but at onesize terminal resistance of other end cross-over connection of communication cable.In existing DeviceNet network communication process, usually employing respectively adds a Device Net plug special at the two ends of backbone network, 121 ohm resistance are linked to each other with the white signal line with the blueness of Device Net netting twine by plug, to reach the effect of the signal reflex of elimination in telecommunication cable.
It is loaded down with trivial details that but prior art resistance is installed connection, is easy to generate short circuit and virtual connection phenomenon, causes network failure, influences the network equipment and normally move; Loosely organized, not compact.
Summary of the invention:
Goal of the invention:
The purpose of this utility model is to provide that a kind of installation is simple, pegging graft puts in place, can not produce short circuit and virtual connection phenomenon, can ensure that the network equipment normally moves, rational in infrastructure, compact network terminal resistive module.
For achieving the above object, the utility model is taked following design: this network terminal resistive module, form by resistance, resistance attachment plug, housing, brace, connecting bolt, described resistance and described resistance attachment plug are installed in the described housing, described resistance is connected with described resistance attachment plug, described brace is installed on the housing two ends, and on described brace, disposes described connecting bolt.
Because the utility model adopts above technical scheme, network terminal resistance is by simply being inserted in resistance attachment plug existing cable erector on the cable, use connecting bolt fastening again, just can closely be connected with network by cable connector, thereby the diminished reflex signal makes network communication normal to the influence of communication line.
Because the utility model adopts above technical scheme, reached install simple, pegging graft puts in place, can not produce short circuit and virtual connection phenomenon, can ensure that the network equipment normally moves, rational in infrastructure, compact purpose.
Description of drawings:
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model structural representation
Embodiment:
As shown in Figure 1, this network terminal resistive module of the utility model, form by resistance 1, resistance attachment plug 2, housing 3, brace 4, connecting bolt 5, described resistance 1 and described resistance attachment plug 2 are installed in the described housing 3, described resistance 1 is connected with described resistance attachment plug 2, described brace 4 is installed on housing 3 two ends, and on described brace 4, disposes described connecting bolt 5.
Because the utility model adopts above technical scheme, network terminal resistance 1 is by simply being inserted in resistance attachment plug 2 existing cable erector on the cable, be fastened on the cable erector with connecting bolt 5 again, just can closely be connected with network by cable connector, thereby the diminished reflex signal makes network communication normal to the influence of communication line.
Below only be an embodiment of the present utility model, any based on equivalents of the present utility model all within protection range of the present utility model.
