Abstract
The invention discloses a self-riveting rivet which is provided with a cap and a bore log. The cap is fixedly arranged on one end face of the bore log, and the lateral side of the upper edge of one end of the bore log close to the cap is recessed to form an annular groove. Since the bore log is provided with the annular groove, part of materials are extruded into the annular groove by the lateral side of a metal part after the bore log of the rivet is disposed into a hole of the metal part, and accordingly, self-riveting of the rivet is realized. The rivet is simple and quick to mount and free of cracking and other adverse problems caused by impact.
Description
Technical field
The present invention relates to a kind of rivet, relate to specifically a kind of from the riveted rivet.
Background technique
At electronic components such as mobile phone, computers, especially in the processing procedure of multilayer circuit board, generally have being fixedly connected with between multilayer circuit board or other elements.At present, main Placement has two kinds, and the one, adopt laser beam welding, but laser welding equipment involves great expense, the butt-welding fitting status requirement is very accurate simultaneously, when therefore welding, must guarantee that the final position of weldment needs with laser beam, the solder joint that impacts is aimed at.Another kind is to utilize the metal-made rivet to be arranged on positioning hole, then impacts rivet with red needle, makes the open-ended end of rivet be hit and be out of shape and open and be pressed on fixture, to form the rivet stationary state.But; during actual job; when rivet pipe section opening end opens distortion being hit; often powerful cracking can occur and produce jointly a small amount of conduction fracture detritus, and drop on circuit board to be connected or other devices, cause short circuit; Given this shortcoming; have part manufacturer to change metal rivet into plastic material, but the rivet poor ductility of plastic material often can be broken and cause reaching the riveted retention force that the virgin metal rivet has when impacting with red needle.In addition, above-mentioned two kinds of means of fixation operate more loaded down with trivial detailsly, and installation efficiency is also lower.
Summary of the invention
In order to overcome defects, the invention provides a kind ofly from the riveted rivet, not only install simply, rapidly, and can not produce to break and wait other bad phenomenon generations.
The present invention for the technological scheme that solves its technical problem and adopt is: a kind of from the riveted rivet, this rivet has a cap head and hole post two-part, described cap head is fixedly arranged on the end face of described Kong Zhu, and described Kong Zhu forms an annular recess near circumferentially concaving along its side on an end of described cap head.
As a further improvement on the present invention, described cap head has columniform the first cap head and the second cap head, and described the second cap head is between described the first cap head and Kong Zhu, and the diameter of the first cap head is greater than the diameter of the second cap head.
As a further improvement on the present invention, described the first cap head is 0.15cm along the width of its axis, and described the second cap head is 0.30cm along the width of its axis.
As a further improvement on the present invention, the described annular recess of described Kong Zhucong is diminished greatly by little the change gradually more gradually to the diameter away from the first end of described cap.
As a further improvement on the present invention, described Kong Zhu is identical with the diameter of described annular recess away from the diameter of an end face of described cap head.
As a further improvement on the present invention, the diameter at described annular recess place is 0.92cm, and the maximum diameter of described Kong Zhu is 1.0cm, and minimum diameter is 0.92cm.
As a further improvement on the present invention, the annular recess of described Kong Zhu is between described cap head and be 0.05cm along the width of its axis, and the annular recess of described Kong Zhu is to it away from the first end of described cap and be 0.50cm along the width of its axis.
The invention has the beneficial effects as follows: this rivet is because Kong Zhu is provided with annular recess, so after the Kong Zhu of this rivet inserts position, metalwork hole, because the extruding of metallic material side enters in annular recess the part material, thereby rivet realized from riveted.It is simple, quick that this rivet is installed, and can not produce to impact breaking and other bad phenomenon generations of causing.
Description of drawings
Fig. 1 is cross-sectional view of the present invention;
Fig. 2 is that the present invention uses the status architecture schematic diagram.
By reference to the accompanying drawings, make the following instructions:
1---cap head 11---first cap head
12---second cap head 2---Kong Zhu
21---annular recess
Embodiment
By reference to the accompanying drawings, the present invention is elaborated, but protection scope of the present invention is not limited to following embodiment, the simple equivalence of namely in every case being done with the present patent application the scope of the claims and description changes and modifies, within all still belonging to patent covering scope of the present invention.
As shown in Figure 1, a kind of from the riveted rivet, this rivet has a cap head 1 and hole post 2 two-part, and described cap head is fixedly arranged on the end face of described Kong Zhu, it is characterized in that: described Kong Zhu forms an annular recess 21 near circumferentially concaving along its side on an end of described cap head.Like this, after this rivet is pressed in the metalwork hole, as shown in Figure 2, the side effect of being squeezed due to the metalwork hole, the part material is pushed in the annular recess 21 that is injected on the rivet hole post, thereby reach the effect of fixing rivet, do not impact rivet and do not need to re-use red needle, install very convenient.
Preferably, described cap head has columniform the first cap head 11 and the second cap head 12, and described the second cap head is between described the first cap head and Kong Zhu, and the diameter of the first cap head is greater than the diameter of the second cap head.
Preferably, described the first cap head is 0.15cm along the width of its axis, and described the second cap head is 0.30cm along the width of its axis.
Preferably, the described annular recess of described Kong Zhucong is diminished greatly by little the change gradually more gradually to the diameter away from the first end of described cap.
Preferably, described Kong Zhu is identical with the diameter of described annular recess away from the diameter of an end face of described cap head.
Preferably, the diameter at described annular recess place is 0.92cm, and the maximum diameter of described Kong Zhu is 1.0cm, and minimum diameter is 0.92cm.
Preferably, the annular recess of described Kong Zhu is between described cap head and be 0.05cm along the width of its axis, and the annular recess of described Kong Zhu is to it away from the first end of described cap and be 0.50cm along the width of its axis.
