Abstract
The utility model discloses a terminal row test connecting head comprising a plug head used for connecting with a terminal row, one end of the plug head is provided with an outer screw thread, the other end is connected with a sleeve tube into which a test plug head can be plugged, an insulation layer is sleeved on the outer side of the sleeve tube, and an electric conduction inner container is arranged in the sleeve tube. According to the terminal row test connecting head, an analog quantity can be input into a protection device when a terminal row connecting wire is not opened, and therefore work efficiency and security are improved.
Description
Technical field
The utility model relates to a kind of Power tabs, particularly a kind of terminal board test joint.
Background technology
The secondary line terminal board of relay-set is divided into testing terminal row and non-test terminal board, Figure 2 shows that testing terminal row, Figure 3 shows that non-test terminal board, Figure 4 shows that existing test plug 6.On existing testing terminal row 1, be directly provided with test socket 2 as shown in Figure 2, cable core 3 is directly connected on testing terminal row 1.And on non-test terminal board 4 as shown in Figure 3, cable core 3 is to be also directly connected on non-test terminal board, but do not test socket on non-test terminal board 4, only has a screw 5, it is originally used for installing short-circuit piece (not shown in Fig. 3), cannot insert test plug, and traditional way is that cable core 3 is pulled down from terminal board, be clipped on cable core 3 and pass into analog quantity with test clamp, the very inconvenient certain risk that also has is debugged in maintenance.
Utility model content
In view of the problems referred to above that prior art exists, the purpose of this utility model be to provide a kind of can be in the situation that not opening terminal row wiring by analog input to the terminal board test joint in protective device.
To achieve these goals, the terminal board test joint that the utility model provides, comprise the plug for splicing ear row, one end of described plug has external screw thread, the other end is connected with a sleeve pipe plugging for confession test plug, described outside of sleeve is arranged with insulating barrier, is provided with conduction inner bag in described sleeve pipe.
As preferably, described conduction inner bag is copper inner bag.
Be compared to prior art, adopt terminal board test joint of the present utility model can be in the situation that not opening terminal row wiring by analog input in protective device, improved operating efficiency and fail safe.
Brief description of the drawings
Fig. 1 is the structural representation (wherein showing test plug) of terminal board test joint of the present utility model.
Fig. 2 is existing testing terminal row's structural representation.
Fig. 3 is the structural representation of existing non-test terminal board.
Fig. 4 is the structural representation of existing test plug.
Embodiment
Below in conjunction with accompanying drawing, structure of the present utility model is further described in detail.
As shown in Figure 1, the terminal board test joint that the utility model provides, comprise the plug 10 for splicing ear row, one end of described plug 10 has external screw thread, the other end is connected with a sleeve pipe 11 plugging for confession test plug 6, described sleeve pipe 11 outsides are arranged with insulating barrier 13, are provided with conduction inner bag 12 in described sleeve pipe 11.As shown in Figure 2, Figure 3 and Figure 4, on existing testing terminal row 1, there is test socket 2, can directly plug for test plug 6.But on existing non-test terminal board 4, do not establish jack, and be only provided with for the screw 5 that short-circuit piece is installed, therefore can adopt the external screw thread of one end of the plug 10 of terminal board test joint of the present utility model to be directly threaded onto screw 5, can fix short-circuit piece simultaneously.In addition, the sleeve pipe 11 of the other end setting by plug 10 can form jack, and the insulating barrier 13 in sleeve pipe 11 outsides can ensure fail safe, and conduction inner bag 12 ensures to conduct unimpeded.So far, when operation, only need existing test plug 6 to insert in the sleeve pipe 11 on plug 10, can be in the situation that not opening terminal row wiring by analog input in protective device, improved operating efficiency and ensured fail safe.
In addition, in the utility model, as preferably, described conduction inner bag 12 is copper inner bag.
Certainly, the above is the preferred implementation of utility model, should be understood that; for those skilled in the art; not departing under the prerequisite of the utility model principle, can also make some improvements and modifications, these improvements and modifications are also considered as protection range of the present utility model.
Claims (2)
1. terminal board test joint, is characterized in that, comprises the plug for splicing ear row, one end of described plug has external screw thread, the other end is connected with a sleeve pipe plugging for confession test plug, and described outside of sleeve is arranged with insulating barrier, is provided with conduction inner bag in described sleeve pipe.
2. terminal board test joint as claimed in claim 1, is characterized in that, described conduction inner bag is copper inner bag.
