Abstract
The utility model discloses an economic type terminal block row for tests. The terminal block row comprises a basic body (1) and an electricity conducting part. It is characterized in such a way that the electricity conducting part comprises a long electricity conducting piece (1), a short electricity conducting piece (2), a sliding component, a testing insertion tube (4), and a wire connection component. The sliding component consists of an upper sliding block (5), a lower sliding block (6), and a sliding block screw (7). The upper sliding block (5) and the lower sliding block (6) are provided with protruding tables (8). The terminal block row of the utility model overcomes the problem that when a terminal block row screws tight a sliding block, the sliding block is prone to come off an electricity conducting piece to further cause poor contact and to pose accidents. The terminal block row of the utility model also has the features of simple manufacturing art and is low costing to make as well.
Description
Technical field
The present invention relates to a kind of low voltage switchgear and control appliance ancillary apparatus, economical test connection terminal board for especially a kind of testing current of using for secondary equipment in power system wiring.
Background technology
In electrical fitting field, prototype version connecting terminal block is to realize one of very important parts of electrical connection, and existing prototype version connecting terminal block mainly contains two kinds of structures:
1, its current-carrying part is made up of bulk metal external member and slide unit, metal external member has comprised conducting strip, test cartridge and connecting part, this structure is on-off circuit effectively, complete testing current, and there is higher fail safe, it is high that but metal external member processing technology requires, and causes its cost of manufacture very high;
2, current-carrying part is by being made up of long conducting strip, short conducting strip, slide unit, test insertion tube, connecting part, slide unit is made up of upper and lower slide block and screw, but its test insertion tube is not insulated part and surrounds and fix, and exist while firmly tightening screw, top shoe and sliding block easily rotate dislocation along the direction of tightening, cause loose contact between top shoe and sliding block and conducting strip, have potential safety hazard.
Utility model content
For above-mentioned deficiency, it is a kind of with low cost that the utility model provides, and ensure the Economy Test connecting terminal block of safety in utilization.
The utility model is to realize by such technical scheme: a kind of economical test connection terminal board, is made up of matrix (1) and conductive component.
Conductive component is made up of long conducting strip (2), short conducting strip (3), slide unit, test insertion tube (4), connecting part, and is fixed in matrix (1).
Slide unit is made up of top shoe (5), sliding block (6) and slide block screw (7), on top shoe (5), sliding block (6), is provided with boss (8).
Long conducting strip (5), short conducting strip (6) are provided with slide block slot (13), and described slide unit slides in slide block slot (13).
Connecting part is made up of the pressing line frame (9) and the line pressing bolt (10) that are socketed on long conducting strip (2) and short conducting strip (3).
Test insertion tube (4) is fixed in the circular hole (11) of matrix inside, is connected with short conducting strip (3) with long conducting strip (2) by screw thread.
On short conducting strip, be provided with a square hole (12), as the patchhole of bridgeware, bridgeware can be by two or more terminal short circuits after inserting.
Owing to having adopted said structure, the beneficial effects of the utility model are as follows:
1,, in the time tightening slide block screw (7), boss (8) is inconsistent with slide block slot (13), effectively prevents that slider part from rotating dislocation along the direction of tightening, and skids off slide block slot (13);
2, test insertion tube (4) is fixed in the inner circular hole (11) of matrix (1), be connected by screw thread with short conducting strip (3) with long conducting strip (2), make conducting strip firmly be fixed on matrix (1) inside, the phenomenon that conducting strip (2,3) screws out can not occur.

Embodiment
In order to be more expressly understood the purpose of this utility model, technical scheme and beneficial effect, below in conjunction with accompanying drawing, the utility model is described further, but protection range of the present utility model is not limited in following examples.
As depicted in figs. 1 and 2, a kind of economical test connection terminal board, comprise matrix (1) and conductive component, it is characterized in that: described conductive component is made up of long conducting strip (2), short conducting strip (3), slide unit, test insertion tube (4), connecting part, described slide unit is made up of top shoe (5), sliding block (6) and slide block screw (7).
As shown in Figure 1, Figure 2 and Figure 3, described test insertion tube (4) is fixed in the inner circular hole (11) of matrix (1), is connected with short conducting strip (3) with long conducting strip (2) by screw thread.
As shown in Figure 1, Figure 4 and Figure 5, described long conducting strip (2), short conducting strip (3) are provided with slide block slot (13), and described slide unit slides in slide block slot.
As shown in Figure 2, described connecting part is made up of the pressing line frame (9) and the line pressing bolt (10) that are socketed on long conducting strip (2) and short conducting strip (3).
As shown in Figure 6 and Figure 7, on described top shoe (5), sliding block (6), be provided with boss (8).
In the time of needs making current, make slider part in position shown in Fig. 1, tighten slide block screw (7), top shoe (5), sliding block (6) are clamped described long conducting strip (2), short conducting strip (3), because top shoe (5), sliding block (6) are provided with boss (8), it is inconsistent with the slide block slot (13) that long conducting strip (2), short conducting strip (3) arrange, and slide block can not be skidded off, and ensures safe and reliable.
In the time of needs turn-off current, unscrew slide block screw (7), make sliding block (6) because Action of Gravity Field moves downward, overall slide unit is mobile along the slide block slot (13) in long conducting strip (2), in the time that slide unit and short conducting strip (3) do not come in contact, electric current disconnects.
