Embodiment

The utility model is further described with reference to specific embodiment and accompanying drawing.

A kind of thermometric c-type switchgear wire clamp as shown in Figure 1, Figure 2, described in Fig. 3, it includes the fixed plate 1 with groove 2, The fixed plate 1 is extended with location division 10 along in the setting direction of groove 2, has positioning hole on the location division 10；

The two side of groove 2 in the relative c-type structure in position, and be provided with the groove 2 respectively with the two side position of groove 2 The first briquetting 3, the second briquetting 4 relative and at least one wire to be connected can be pressed on the two side of groove 2 are put, this first Briquetting 3, the pivot joint connection of the second briquetting 4, have in fixed plate 1 through the first briquetting 3, the second briquetting 4 pivot joint medium position and Can be by first briquetting 3, the locking positioning of the second briquetting 4 in the bolt and nut 5 in the fixed plate 1.

Positioning hole on the utility model location division 10 includes circular hole and oval elongated hole, is used as connecting ear, suitable for each The equipment connection such as kind switch, bus bar, isolation switch, fuse switch, wherein, oval elongated hole is used for Primary Location and can fitted Answering property adjustment position, and circular hole coordinates oval elongated hole finally to be positioned.For being directed to separated time in this c-type switchgear wire clamp Draw, primary structure can use following scheme：

Scheme one, the first briquetting 3, there is the spacing C relative with the c-type locations of structures of the two side of groove 2 on the second briquetting 4 Type groove；

There is the spacing C-shaped channel relative with the c-type locations of structures of the side wall of groove 2 one in scheme two, the first briquetting 3, second There is the spacing arc block being engaged with the c-type structure of 2 another side wall of groove on briquetting 4；

There is the spacing arc block being engaged with the c-type structure of the side wall of groove 2 one, the second pressure in scheme three, the first briquetting 3 There is the spacing C-shaped channel relative with the c-type locations of structures of 2 another side wall of groove on block 4.

Three scheme can carry out classification making and apply according to specific wiring requirements, wherein, 2 liang of spacing C-shaped channel and groove Formed between the c-type structure of side wall and treat the locking positioning of connecting wire, and matching somebody with somebody between spacing arc block and the side wall of groove 2 Close, the first briquetting 3, the second briquetting 4 of different size can be used in the fixed plate 1 with identical groove 2, passes through spacing arc Block carries out auxiliary positioning.In order to ensure to treat the stabilization of connecting wire, fixedly positioning, in the c-type structure of the two side of groove 2 With some anti-sliding ribs set along its length；Equally have in spacing C-shaped channel it is some set along its length it is anti- Sliding rib.

The both sides of fixed plate 1 are removably connected with temperature measuring unit 6, and the temperature measuring unit 6 includes the thermometric with assembling circular hole Cylinder 61, it is snug fit at the alarm column 63 being connected by compression spring in the assembling circular hole and with the thermometric cylinder 61, is located at In the thermometric cylinder 61 and for the flexure strip 67 being limited in alarm column 63 in assembling circular hole and on the flexure strip 67 and For releasing the temperature measuring element 68 spacing to alarm column 63 of flexure strip 67 when detecting conductor temperature to be connected and reaching setting value.

Specifically, it is in swallow-tailed stopper slot that the both sides of fixed plate 1 have section along the setting direction of groove 2, and in thermometric list The limited block 64 that can be slidably matched with stopper slot is provided with first 6 side walls, detachably connecting between temperature measuring unit 6 and fixed plate 1 Connect and be connected by the limited block 64 and stopper slot, during cooperation, between the limited block 64 and the stopper slot can interference fits, with Ensure connective stability between the two.Certainly, in practical application, the section of the stopper slot, which is formed, is not limited in dovetail shaped, In every case cross sectional shape is in the structure that upper end port is narrow, lower end base is wide, while limited block 64 is slidably matched therewith, with spacing Groove notch is realized to spacing connection between the two.

Being provided with thermometric cylinder 61 with assembling circular hole has the assembling square hole to occur simultaneously, and has in assembling circular hole one end fits The sealing base 62 of compression spring is positioned, the sealing base 62 is extended with extending seat 66 along assembling square hole, the extending seat 66 Portion has via 65, and the one end of flexure strip 67 is fixed on the extending seat 66, the other end is bent and passes through via 65 and alarm column 63 The limiting stand of end coordinates spacing.

In order to ensure that alarm column 63 smoothly assembles in assembling circular hole, that is, the stop because of flexure strip 67 is avoided to cause alarm column 63 assemblings are difficult, and this example has the end of alarm column 63 tapered transitional for extending to limiting stand position.

Finally, there is guide ring 69, the guide ring 69 is positioned at assembling circular hole and assembling square hole on the port of thermometric cylinder 61 On, and the guide ring 69 is located on alarm column 63 with respect to slip cap.Here for ensure guide ring 69, sealing base 62 respectively with dress With the stable assembling between circular hole, assembling square hole, ring 69 can be directed to, the design of sealing base 62 periphery is in certain bevel angle Degree so that be oriented to during assembling, be finally reached elastic conjunction and realize the stability entirely assembled and fixing.

The technical scheme provided above the utility model embodiment is described in detail, used herein specifically Individual example is set forth to the principle and embodiment of the utility model embodiment, and the explanation of above example is only applicable to help Assistant solves the principle of the utility model embodiment；Meanwhile for those of ordinary skill in the art, implement according to the utility model Example, the there will be changes in embodiment and application, in summary, this specification content should not be construed as To limitation of the present utility model.
