Detailed description of the invention
The present invention is better understood with by following description in any way, is shown below with reference to attached drawing with unrestricted
It is illustrated terminal block according to the present invention.
Fig. 1 is the exploded view of terminal block according to the present invention.
Fig. 2 is the sectional view of the terminal block of Fig. 1.
Fig. 3 is the perspective view of the terminal block of Fig. 1.
Fig. 4 is the perspective view of the connecting band in another application similar to the terminal block of Fig. 1.
Specific embodiment
As shown in figure 1, grounding terminals block 1 according to the present invention includes conductive connecting strap 10, for being fastened on conductive supporting
Clamping piece 20, pinching screw 30 and conductive protection foot 40 on guide rail 2.
Conductive connecting strap 10 includes the first hole 11 with the tapping for determining diameter D.
Clamping piece 20 includes the second hole 21, and the diameter D ' of the tapping in second hole is less than or equal to the first hole of connecting band 10
The diameter D of 11 tapping.
In addition, as shown in Figure 2, clamping piece 20 includes the hook 22 for being intended to contact with the lower part 2a of supporting guide 2.
For protecting foot 40, it is inserted into the shell 23 of clamping piece 20 and aims to ensure that and supporting guide 2
The electrical contact of top 2b.
In addition, protection foot 40 includes the channel 41 for pinching screw 30, which ensure that including connecting band 10, clamping piece
20 and protection foot 40 component combination (cohesion).
As a result, pinching screw 30 be intended to sequentially pass through connecting band 10 the first hole 11, protect foot 40 channel 41 and
Second hole 21 of clamping piece 20.
Pinching screw 30 includes head 31, and the diameter on the head is greater than the diameter D of the tapping in the first hole 11 of connecting band 10,
So that the head can bear against the connecting band 10.
As shown in Figure 1 to Figure 3, bushing 35 can be inserted between screw head 31 and connecting band 10, so as in pinching screw 30
Fastening during protect connecting band 10.
This bushing 35 can also have the function of keeping the fastening of screw 30.
In addition, pinching screw 30 includes first part 32 and second part 33.
First part 32 extends determining length l from screw head 31.
This first part 32 preferably has smooth surface.
The diameter d of this first part 32 is less than the diameter D of the tapping in the first hole 11 of connecting band 10.
Second part 33 extends to the end opposite with screw head 31 of screw 30 from first part 32.
The diameter d ' of the screw thread of second part 33 is substantially equal to the diameter D ' of the tapping in the second hole 21 of clamping piece 20.
The total length L of pinching screw 30, which is greater than, to be separated in the first hole 11 with connecting band 10 and by the second hole 21 and clamping piece
20 separated distances.
The length l of first part 32 determines which is the tapping in the second hole 21 of clamping piece 20 in this way
With when being threadedly engaged of second part 33 of pinching screw 30, and then make connecting band 10 the first hole 11 tapping in face of clamp spiral shell
The first part 32 of nail 30.
As a result, during a kind of method for installing grounding terminals block 1, user executes first step, and first step includes will
The screw thread of the second part 33 of pinching screw 30 is screwed in the tapping in the first hole 11 of connecting band 10, until the of connecting band 10
Until the tapping in one hole 11 faces the first part 32 of pinching screw 30.
In the second step, the screw thread of the second part 33 of pinching screw 30 is screwed to the second hole of clamping piece 20 by user
In 21 tapping.
First embodiment according to the present invention, once first step complete just executable second step, or according to the
Two embodiments, second step can partly execute while first step terminates.
In fact, this identical screw thread of second part 33 and attacking for the second hole 21 of clamping piece 20 when pinching screw 30
When silk cooperation, the screw thread of the second part 33 of pinching screw 30 can cooperate with the tapping in the first hole 11 of connecting band 10.
However, as long as translational motion of the clamping piece 20 on pinching screw is free, the second part of pinching screw 30
32 screw thread simultaneously with this cooperation of the tapping in the second hole 21 of the tapping and clamping piece 20 in the first hole 11 of connecting band 10 just
It is possible.
From at the time of clamping piece 20 applies on the direction of connecting band 10 and reacts on the supporting force of supporting guide 2,
This translational motion is no longer free.
Therefore, in this second embodiment, when the application of clamping piece 20 reacts on the supporting force of supporting guide 2,
The first part 32 of pinching screw 30 must face the first hole 11 of connecting band 10.
When terminal block 1 is mounted on supporting guide 2 not yet and when terminal block 1 is already installed on supporting guide 2,
The installation method can be performed.
Finally, as Fig. 4 is shown, (it is equal to used in the grounding terminals block 1 in connection terminal block using connecting band 10
Connecting band) it is possible.
In this case, the tapping in the first hole 11 of connecting band 10 is intended to and the screw thread for the terminal 51 for connecting current divider 50
Cooperation.
Although the present invention has been combined specific embodiment, example is described, it is evident that it is not to appoint
Where formula limits and including all technically equivalent ones of described device and the combination of these devices.
The surface of the first part 32 of pinching screw is not necessarily smooth as a result, but it can have permission pinching screw
Institute (free to slide for translation and rotation) free to slide in the tapping in the first hole 11 of connecting band 10,30 first part 32
There are aspect and form of ownership.
