Background technology
Electric energy meter is a kind of instrument of often using in the power technology field, in order to guarantee the use of correct safety, guarantees the accuracy of electric energy metrical, need require electric energy meter is examined and determine according to rules, will carry out the operation of acquisition pulse signal in verification process.But because the taps connection terminal model of using in the pulse signal acquisition process is a lot, the diversified in specifications of each producer causes, so in verification process, need to carry out distribution for the connection terminal of two ends different model, method commonly used at present is that cable is broken the back rewiring, complex operation in the wiring process, influenced work efficiency, and because wiring is provisional, can be because the effective shielding of wiring loose contact or shortage causes the reduction of burst transmissions quality.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides simple in structure, easy and simple to handle and connects the firm polylinker termination that electric energy meter detects that is used for.
The technical scheme that the utility model is taked is:
A kind of polylinker termination that is used for the electric energy meter detection, it is characterized in that: comprise housing, two line select switches and two groups of cables, each line select switch all with one group of cable being inlaid on the housing of contraposition mutually, the stationary contact of two line select switches interconnects, the moving contact of each line select switch all can be done the circumference rotation and contact with the end of every cable of space in one group of cable, and the other end of cable is equipped with connection terminal.
And, on housing, also be embedded with and the moving contact of each line select switch Slave line of contraposition mutually.
And described line select switch is a knob switch.
Advantage of the present utility model and good effect are:
The utility model is simple in structure, easy and simple to handle, two line select switches and two groups of cables are being inlaid on the housing of contraposition mutually, every cable outboard end in every group of cable all is equipped with the connection terminal of various models, the connection terminal of different model has made things convenient for the tester to connect different equipment with the acquisition pulse signal like this, has solved in the prior art because low, the ropy problem of burst transmissions of work efficiency that frequent wiring causes.And, on housing, also being embedded with Slave line, this cable can more be installed the connection terminal of different model according to the needs of difference calibrating object, has expanded the scope of application of device greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of enclosure interior.
Embodiment
Below in conjunction with embodiment, the utility model is further specified, following embodiment is illustrative, is not determinate, can not limit protection domain of the present utility model with following embodiment.
A kind of polylinker termination that is used for the electric energy meter detection, shown in Fig. 1～2, innovation of the present utility model is: comprise housing 1, two line select switches 2 and two groups of cables 8, each line select switch all with one group of cable being inlaid on the housing of contraposition mutually, the stationary contact 4 of two line select switches interconnects, the moving contact 5 of each line select switch all can be done the circumference rotation and contact with the end of every cable of space in one group of cable, and the other end of cable is equipped with connection terminal.The syndeton of cable and housing is: an end of cable is inlaid on the housing, and its end that puts in the housing installs sheet metal 7, and the other end of this cable is installed connection terminal.
In the present embodiment, line select switch is a knob switch, and the turning axle that this knob switch stretches in the housing is a stationary contact, and the fork that is fixed on the turning axle is a moving contact.With the knob switch in left side mutually one group of cable of contraposition comprise four cables, the outboard end of this cable is installed sea salt five hole connection terminals respectively, is thought to reach five hole connection terminals, raise into five hole connection terminals and BNC connection terminal, with the knob switch on right side mutually one group of cable of contraposition comprise two cables, the outboard end of this cable is installed BNC connection terminal and double end crocodile clip connection terminal respectively.The contraposition of every side knob switch homogeneous phase be provided with Slave line so that the function of expanding unit, above-mentioned various connection terminals are all bought from the market, also can adopt other connection terminal commonly used.
Because connection terminal is a double wire system, reach five hole connection terminals and double end crocodile clip connection terminal is an example with the think of in scheming, the cable that connects these two connection terminals is made of two leads, the end that every lead stretches in the housing all installs a sheet metal, these two sheet metals contact with two contacts 6 on the knob switch fork, two contacts are connected with contact on another rotary switch fork by connecting line 3, other connection terminal and Slave line all adopt double wire system, its structure and with the way of contact of the fork of rotary switch and think of to reach five hole connection terminals identical with double end crocodile connection terminal.
The course of work of the present utility model is:
The tester is torqued into scale 2 with the left side knob switch, this moment, the fork of knob switch was communicated with sea salt five hole connection terminals, the tester is connected equipment on the sea salt five hole connection terminals, the tester is torqued into scale 2 with the right side knob switch, this moment, the fork of knob switch was communicated with double end crocodile clip connection terminal, the tester is connected equipment on the double end crocodile clip connection terminal, finish wiring after, the tester promptly can begin the acquisition pulse signal.
The utility model is simple in structure, easy and simple to handle, two line select switches and two groups of cables are being inlaid on the housing of contraposition mutually, the connection terminal of different model has made things convenient for the tester to connect different equipment with the acquisition pulse signal, has solved in the prior art because low, the ropy problem of burst transmissions of work efficiency that frequent wiring causes.And, on housing, also being embedded with Slave line, this cable can more be installed the connection terminal of different model according to the needs of difference calibrating object, has expanded the scope of application of device greatly.
