Description
Technical field
The invention belongs to electrical equipment technical field more particularly to a kind of terminal blocks for preventing wiring loosening from falling, and are applicable in
In each connecting terminal of electric system.
Background technique
Terminal block is that multiple or multiple groups mutually insulated the terminals of carrying form and are used to fix the insulation position of supporter.End
The effect of son row is exactly the connection of equipment and screen external equipment in shielding, and plays the role of transmission.
Existing terminal block pattern is one section of sheet metal being enclosed in inside ambroin, and both ends have hole can be inserted to lead
Line has screw for tightening or loosening, and when wiring accesses terminal block, circuit is connected.
The terminal block of existing original basis there are the shortcomings that it is as follows:
The existing not set anti-loosening dropping device of terminal block, there are connecting terminals to lead to contact not since vibration causes easily to loosen
It is good, single patch is easy to appear under harsh conditions and drops out connecting groove, is caused other circuits short-circuit, is caused unit trip or kindling etc.
Situation, security risk are larger.
Summary of the invention
The present invention is directed to the above-mentioned prior art, and existing terminal loosens because shaking pigtail splice in actual use
It falls, and causes various electrical equipment secondary circuits because terminal loosening can not be connected and circuit the end of a thread drops out and causes the short circuit of other circuits
Or the problems such as ground connection, and propose a kind of terminal block for preventing wiring loosening from falling.It is simple its purpose is to provide a kind of structure,
Design is reasonable, the terminal block that wiring loosening can be effectively prevent to fall.
The technical solution adopted by the present invention to solve the technical problems is:
The terminal block that wiring loosening is fallen is prevented, including terminal block: installing an external fastening devices additional on the top of terminal block, tightly
It is fixedly mounted with and is set to the insulation rectangular plastic materials and parts that internal reservation has line channel and fixing bolt；The external fastening devices include tight
Fixing bolt, compress gasket, limit fastener and hold-down bolt, clamp device are connected in terminal block；Limit fastener is by compress gasket
It is connected on the line channel of internal reservation；Terminal block is internally connected with upper and lower ends connection sheet；Fixation is connected in terminal block
Buckle A and fixed card buckle B.
The fastening bolt is located at the both ends of clamp device, for external fastening devices are fixedly connected in terminal block.
The compress gasket, for compressing cable after conducting wire passes through, passes through in the state of bouncing is protruded outward after compression
Hold-down bolt is fastened again.
The fixed card buckle A and fixed card buckle B is located on rear side of terminal block for the connection between track, this buckle shape
Consistent with track pattern, when use, will snap connection in orbit.
The upper and lower ends connection sheet is connected to inside terminal block Inner plastic part, and effect is that two cables connect connection up and down
Head, as upper and lower two cable insertion end row, fastening bolt can fasten cable, and upper and lower ends cable can be led at this time
It is logical.
Lead is penetrated in reserved line channel mouth on the external fastening devices, inside external fastening devices
In reserved line channel, it is fastened and fixed the bolt of lead and then is adjusted line-spacing, by external fastening bolt after adjustment
Fastening, and hold-down bolt is adjusted, so that lead is carried out secondary fixation.
The present invention has the following advantages and beneficial effects:
The present invention installs an external fastening devices additional by the top of the terminal block in original basis, so as to prevent wiring loosening
It falls, improves safety coefficient.Avoid various electrical equipment secondary circuits because terminal loosening can not be connected and circuit the end of a thread drops out and draws
The generation for the problems such as sending out the short circuit of other circuits or ground connection.Due to having installed external fastening devices additional in the present invention, there is structure
Simply, operation is simple, designs reasonable distinguishing feature, and the safety coefficient of production operation can be made to be significantly improved,
Certain guaranteeing role is played to the personal safety of operating personnel.
Detailed description of the invention
Understand for the ease of those of ordinary skill in the art and implement the present invention, with reference to the accompanying drawing and specific embodiment
The present invention is described in further detail, and the following examples are intended to illustrate the invention, it is to be understood that protection model of the invention
It encloses and is not limited by the specific implementation.
Fig. 1 is overall structure diagram of the invention.
In figure: terminal block 1, external fastening devices 2, fastening bolt 3, compress gasket 4, limit fastener 5, hold-down bolt 6, Gu
Surely A7, fixed card buckle B8, the bolt 9 of anchor leg, upper and lower ends connection sheet 10, lead 11 are buckled.
Specific embodiment
The present invention is a kind of terminal block for preventing wiring loosening from falling, as shown in Figure 1, Fig. 1 is overall structure of the invention
Schematic diagram.An external fastening devices 2 are installed additional by the top of the terminal block 1 in original basis, so that realizing prevents wiring loosening
It falls, improves safety coefficient.
The structure of clamp device 2 of the present invention is the insulation rectangle plastics for being reserved with line channel and fixing bolt
Part.Wherein external fastening devices 2 include fastening bolt 3, compress gasket 4, limit fastener 5 and hold-down bolt 6.
The fastening bolt 3 is located at the both ends of clamp device 2, for fixing external fastening devices 2.Fastening bolt 3 can be with
Terminal block main body is attached, and external fastening devices 2 can be fixed in terminal block in this way.By compress gasket 4, limit fastener 5,
Hold-down bolt 6 forms the main clamp device in 2 inner passage of external fastening devices, and compress gasket 4 is fixed on inside by limit fastener 5
On line channel, cable is compressed after conducting wire passes through in the state of bouncing is protruded outward, passes through compression after compression by compress gasket
Bolt 6 is fastened again.
The fixed card buckle A7 and fixed card buckle B8 is located on rear side of terminal block for the connection between track, this snap-type
Shape is consistent with track pattern, and buckle can be directly anchored on track when in use.
The specific structure of the upper and lower ends connection sheet 10 is: upper and lower ends connection sheet 10 is connected to terminal block Inner plastic
Inside part, effect is upper and lower two cable connectors of connection, and as upper and lower two cable insertion end row, fastening bolt 9 can be incited somebody to action
Cable fastening, upper and lower ends cable can be connected at this time.
The present invention in the specific implementation, first before lead 11 does not access terminal block 1, is first stayed line channel mouth to penetrate
In internal reservation line channel on external fastening devices 2, then access in terminal block 1.It is fastened and fixed after the bolt 9 of lead,
It is adjusted line-spacing again, fastens external fastening bolt 3 after adjustment, and adjust hold-down bolt 6, to play lead 11
Carry out the effect of secondary fixation.
