Abstract
The utility model discloses a self-riveting rivet. The self-riveting rivet is provided with a cap and a bore column, wherein the cap is fixedly arranged on one end face of the bore column, and the end, close to the cap, of the bore column is concave inwards in the circumferential direction of the lateral side to form an annular groove. According to the self-riveting rivet, the annular groove is formed in the bore column, part of a metal material enters the annular groove due to the squeezing of the lateral side of the metal material after the bore column of the rivet is placed into a hole of a metal part, and therefore, self-riveting of the rivet is achieved. The self-riveting rivet has the advantages of being simple and fast in installation and capable of avoiding fracture caused by impact and other negative phenomena.
Description
Technical field
The utility model relates to a kind of rivet, relates to a kind of from the riveted rivet specifically.
Background technique
At electronic components such as mobile phone, computers, especially in the processing procedure of multilayer circuit board, generally have fixedly connected between multilayer circuit board or other elements.At present, main Placement has two kinds, and the one, adopt laser beam welding, but laser beam welding equipment manufacturing cost costliness is very accurate to the weldment status requirement simultaneously, when therefore welding, must guarantee that the final position of weldment needs with laser beam the solder joint that impacts to be aimed at.Another kind is to utilize metal rivet processed to be arranged on the positioning hole, impacts rivet with red needle again, and the open-ended end that makes rivet is hit and is out of shape and opens and be pressed on the fixture, to form the rivet stationary state.But; during actual job; when rivet pipe portion opening end opens distortion being hit; powerful cracking takes place and produces a spot of conduction fracture detritus jointly in regular meeting, and drops on circuit board to be connected or other devices, causes short circuit; Given this shortcoming; there is part manufacturer to change metal rivet into plastic material, but the rivet poor ductility of plastic material, when impacting with red needle, breaks and cause to reach the riveted retention force that the virgin metal rivet has through regular meeting.In addition, above-mentioned two kinds of means of fixation are operated more loaded down with trivial detailsly, and installation efficiency is also lower.
Summary of the invention
In order to overcome above-mentioned defective, it is a kind of from the riveted rivet that the utility model provides, and not only installs simply, rapidly, and can not produce to break and wait other bad phenomenon to take place.
The utility model 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 its side, an end upper edge of the close described cap head of described Kong Zhu circumferentially concaves and forms an annular recess.
As further improvement of the utility model, described cap head has the columniform first cap head and the second cap head, and the described second cap head is between the described 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 further improvement of the utility model, the described first cap head is 0.15cm along the width of its axis, and the described second cap head is 0.30cm along the width of its axis.
As further improvement of the utility model, 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 further improvement of the utility model, 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 further improvement of the utility model, 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 further improvement of the utility model, the annular recess of described Kong Zhu is to being 0.05cm between the described cap head and along the width of its axis, and the annular recess of described Kong Zhu is 0.50cm to it away from the first end of described cap and along the width of its axis.
The beneficial effects of the utility model are: 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 the annular recess 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 the utility model cross-sectional view;
Fig. 2 uses the status architecture schematic representation for the utility model.
By reference to the accompanying drawings, make the following instructions:
1---cap head 11---, the first cap head
12---second cap head 2---Kong Zhu
21---annular recess
Embodiment
By reference to the accompanying drawings; the utility model is elaborated; but protection domain of the present utility model is not limited to following embodiment, and namely the simple equivalent of being done with the utility model claim and description in every case changes and modifies, and all still belongs within the utility model patent covering scope.
As shown in Figure 1, a kind of from the riveted rivet, this rivet has a cap head 1 and a 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: its side, an end upper edge of the close described cap head of described Kong Zhu circumferentially concaves and forms an annular recess 21.Like this, after this rivet is pressed in the metalwork hole, as shown in Figure 2, because the side effect of being squeezed in 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 the columniform first cap head 11 and the second cap head 12, and the described second cap head is between the described 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, the described first cap head is 0.15cm along the width of its axis, and the described 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 to being 0.05cm between the described cap head and along the width of its axis, and the annular recess of described Kong Zhu is 0.50cm to it away from the first end of described cap and along the width of its axis.
