The connecting block inside the existing connecting terminal for the heater usually adopts copper and is cylindrical, the connecting block is easy to deform due to excessive force during installation, and the connecting block is slightly deformed due to overhigh temperature during heating, so that the service life is shortened.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a solve above-mentioned technical problem.
In order to achieve the above purpose, the technical scheme of the utility model is that: the utility model provides a binding post of loss of pressure prevention, includes ceramic body, still includes the terminal block, be provided with the rectangle passageway on the ceramic body terminal surface, the terminal block terminal surface is the rectangle, the terminal block sets up in the rectangle passageway, the terminal block terminal surface is provided with the wiring hole that runs through, the terminal block passes through the fix with screw in ceramic body is internal, the terminal block is the chromium steel.
Preferably, the top of the ceramic body is provided with a screw positioning hole, and the screw positioning hole is positioned above the rectangular channel.
Preferably, the number of the rectangular channels is two, the number of the screw positioning holes is four, the number of the screws is four, and one rectangular channel corresponds to two screw positioning holes.
Preferably, the middle of the top of the ceramic body is provided with a mounting hole.
Compared with the prior art, the beneficial effects of the utility model are that: compared with the traditional round structure, the wiring block with the rectangular channel and the rectangular channel is more uniform in stress and better in use effect, the wiring block made of chromium steel can not deform under the conditions of high temperature and large pressure, and the service life is longer.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
It should be noted that, if directional indications (such as upper, lower, left, right, front and rear … …) are involved in the embodiment of the present invention, the directional indications are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indications are changed accordingly.
In addition, if there is a description relating to "first", "second", etc. in the embodiments of the present invention, the description of "first", "second", etc. is for descriptive purposes only and is not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions in the embodiments may be combined with each other, but it must be based on the realization of those skilled in the art, and when the technical solutions are contradictory or cannot be realized, the combination of the technical solutions should not be considered to exist, and is not within the protection scope of the present invention.
As shown in fig. 1-3, the embodiment of the utility model provides a prevent binding post of pressure loss, including ceramic body 1, still include junction block 2, be provided with rectangle passageway 3 on the 1 terminal surface of ceramic body, 2 terminal surfaces of junction block are the rectangle, junction block 2 sets up in the rectangle passageway 3, 2 terminal surfaces of junction block are provided with the wiring hole 4 that runs through, junction block 2 passes through screw 5 to be fixed in the ceramic body 1, junction block 2 is the chromium steel. When using, the line and the power cord of product connect respectively 3 both ends of rectangle passageway compress tightly the line through screw 5 in the wiring hole 4, realize that the circuit switches on, because the line can generate heat when the circuit switch-on, the traditional junction block that adopts copper has good heat conductivity, can make the junction block of copper probably have the deformation influence and use wholly when screwing up screw 5. The lug 2 that adopts rectangle passageway 3 and rectangle compares in traditional circular structure atress more even, and the result of use is better, and the lug 2 that adopts chromium steel can make lug 2 can not warp under high temperature and big pressure condition, and life is more permanent.
In this embodiment, a screw positioning hole 6 is disposed at the top of the ceramic body 1, and the screw positioning hole 6 is located above the rectangular channel 3. The screw 5 is installed from the screw positioning hole 6, the screw 5 is a socket head cap screw, and a wire is pressed in the wiring hole 4 of the wiring block 2 by rotating the screw 5.
Preferably, the number of the rectangular channels 3 is two, the number of the screw positioning holes 6 is four, the number of the screws 5 is four, and one rectangular channel 3 corresponds to two screw positioning holes 6. The arrangement of the rectangular channel 3, the screws 5 and the screw positioning holes 6 is determined according to the requirements of products, and because the products have two wires, the products need to correspond to the two rectangular channels 3, the four screws 5 and the screw positioning holes 6, and two power lines need to be connected at the same time.
The middle of the top of the ceramic body 1 is provided with a mounting hole 7. The mounting holes 7 are used to fix the entire product in a specific position.
It is obvious that the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not limitations to the embodiments of the present invention.
