Abstract
The present invention relates to a boss having a self-hook, the boss having a self-hook formed in the second component to be coupled to the hole formed in the first component, in order to join the two components, one side of the second component A boss formed to protrude from and coupled through the hole; And a hook protruding from the side surface of the boss to press the area of the surface opposite to the contact surface of the first component to be in close contact with the second component. Accordingly, even in a narrow work space, two different parts may be brought into close contact with each other to allow fusion.
Description
The present invention relates to a boss with a self hook. More specifically, the present invention relates to a boss having a self-hook which allows fusion by contacting two parts without using fixtures such as jigs in the process of joining two parts to make one part.
In order to complete a part having a predetermined shape among the parts constituting the automobile, one part is often manufactured in a state where parts of the parts overlap each other. At this time, the overlapped portions are joined by applying heat or pressure.

In order to solve this problem, a tapping screw may be used in a narrow space, but it is difficult to solve a problem in which weight and cost increase due to the use of the tapping screw.
The present invention is to solve the above-mentioned problems of the prior art, an object of the present invention to provide a boss having a self-hook capable of thermally bonding two different parts in a narrow working space without a separate fixing mechanism. It is done.
According to the present invention, in order to join the two parts, a boss having a self-hook formed in the second part to be coupled to a hole formed in the first part, protruding from one side of the second part A boss coupled through the hole; It is achieved by a boss having a self-hook comprising a hook protruding from the side of the boss to press a region of the surface opposite to the contact surface of the first component to be in close contact with the second component. do.
Here, the first component may include a coupling groove formed to fix the hook in an area where one end of the hook is pressed.
And, the hook is characterized in that it is formed inclined in the opposite direction of the direction in which the boss is inserted.
The first component and the second component may be fused by applying heat to the tip of the boss while the boss is coupled to the hole.
On the other hand, the boss may further include a fat groove formed on one side of the lower.
In addition, the first component may further include a filling part formed at an edge of the hole of the surface on which the coupling groove is formed so as to prevent the melt formed by the heat applied to the tip of the boss from invading the fat loss groove.
The boss having a self-hook according to an embodiment of the present invention having the configuration as described above allows two different parts to be in close contact with each other even in a narrow work space. Accordingly, the quality of the two different parts can be improved by preventing the joints and the step caused by the gap after joining in advance.
In addition, since the temporary assembly can be performed without using a jig before welding, assembling convenience can be ensured.
In addition, since the pressing process of the jig is not required during welding, the cycle time and the cost of equipment investment are reduced.
