Detailed Description
The plastic shell assembly inner rivet 8 comprises a limiting platform 1, a barb 2, a plastic shell I3, a plastic shell II 4, an inner rivet hole 5, an inner rivet assembly surface 6 and a shell assembly surface 7.
As shown in fig. 1 and 2, the integral structure comprises an inner rivet and a shell, wherein the inner rivet is composed of a limiting platform 1 and barbs 2, the barbs 2 are positioned on two sides of the limiting platform 1, the shell is composed of a first plastic shell 3, an inner rivet assembling surface 6, a shell assembling surface 7 and a second plastic shell 4, inner rivet holes 5 are arranged in the first plastic shell 3 and the second plastic shell 4, and the inner rivet assembling surface 6 of the inner rivet hole 5 is lower than the shell assembling surface 7 of the shell.
As shown in fig. 3, the barb 2 opens toward the stopper 1. The barb 2 is configured to facilitate connection with the first plastic shell 3 and the second plastic shell 4.
As shown in figure 4, the diameter a of the barbs 2 is 2.5mm to 4mm and the tip angle e of the barbs is 40 DEG to 90 deg.
Preferred embodiment(s) of the invention
The diameter a of the barb 2 is 3.5mm, and if the diameter is too small, the barb strength is insufficient; too large a diameter takes up more space inside the housing.
The barb closed angle e is 60 degrees, the closed angle is too small, the inner rivet is easy to fall off after being assembled, the closed angle is too large, the assembly guide is insufficient, and the inner rivet is difficult to assemble.
As shown in FIG. 4, the length b of both sides of the female rivet is 5mm to 10mm, and the number of barbs 2 of both sides is 3 to 6. The number of barbs 2 on both sides may be the same or different, e.g., 3 barbs on one side and 4 barbs on the other side.
Preferred embodiment(s) of the invention
The length b of one side of the inner rivet is 7mm, and if the length of one side of the inner rivet is too short, no sufficient space is provided for arranging barbs; if the length is too long, the inner rivet is not easy to be formed and will occupy more space for assembling the inner part of the housing
The number of barbs on two sides is preferably 4, and the number of barbs is less, so that the inner rivet does not have enough holding force after being assembled; the number of barbs is large, so that the inner rivet is not easy to assemble
As shown in FIG. 4, the height c of the position limiting table 1 is 1mm to 3mm, and the diameter d of the position limiting table 1 is 4mm to 10 mm.
Preferred embodiment(s) of the invention
The height c of the limiting table is 2mm, and the limiting table is small in height, so that the strength of the limiting table is insufficient, and the limiting table is easy to break or deform after assembly; too great a height wastes raw material for the inner rivets and takes up more space for the internal assembly of the housing.
The diameter d of the limiting table is 6mm, and the limiting function cannot be realized if the diameter of the limiting table is smaller; the larger diameter wastes raw material for the inner rivet and takes up more space for the inner assembly of the housing.
As shown in fig. 2, the inner rivet hole 5 diameter f is smaller than the barb 2 diameter a by a value of 0.2mm to 0.5 mm. The interference between the barb 2 and the inner rivet hole 5 after the inner rivet is assembled is ensured.
The height g of the inner rivet mounting face 6 to the housing mounting face 7 is 0.5mm to 2 mm.
Examples
As shown in fig. 5, in order to pre-install the inner rivet 8, one end of the inner rivet 8 is fitted into the inner rivet hole 5 of the first plastic housing 3;
as shown in fig. 6, after the inner rivet 8 is preassembled, the limiting table 1 is contacted with the inner rivet assembling surface 6 at the moment;
as shown in fig. 7, before the housing is assembled, the other side of the inner rivet 8 is assembled into the inner rivet hole 8 of the second plastic housing 4;
as shown in fig. 8, after the housing is assembled, the plastic housing one 3 is contacted with the housing assembling surface 7 of the plastic housing two 4, and the number of the inner rivets for assembling in the plastic housing is 4 to 10.
