Description
Technical Field
The invention relates to a self-buckling structure, in particular to a connector mounting self-buckling structure.
Background
The self-buckling structure is a convenient, quick and economical product assembling method, because the combined part of the buckling positions is formed simultaneously when producing a finished product, other locking accessories such as screws, mesons and the like do not need to be matched during assembling, and only two buckling positions which need to be combined are matched and buckled mutually.
When the product is buckled and assembled, the upper cover is cracked when four corners are pressed down in the assembling process because the external supporting force is too large (the position of the upper cover is the position of the injection molding combination line), so that the reject ratio is 6%; in the pressing process, because the corner is excessive in the middle, one corner of the product is not pressed into the product to be clamped and deformed, and the reject ratio is 2%.

The invention aims to provide a connector mounting self-buckling structure, wherein the risk of cracking of an upper cover when four corners are pressed downwards in the assembling process is avoided, and the phenomenon that one corner is not pressed in and is deformed by being clamped is avoided.
The technical purpose of the invention is realized by the following technical scheme:
a connector-mounting self-clinching structure comprising:
the upper cover is provided with a bayonet on the periphery of the opening of the upper cover;
the outer peripheral side of the opening of the lower shell is provided with a clamping block which is matched with the bayonet to realize buckling connection, and the outer surface of the clamping block is an arc surface.
Preferably, the bottom of the fixture block is set to be a horizontal plane.
Preferably, the upper cover comprises a first cover body, a circle of stop block horizontally extends outwards from the opening end face of the first cover body, a circle of surrounding shell is vertically extended downwards from the stop block, and the bayonet is arranged on the surrounding shell.
Preferably, the outer side wall of the first cover body is provided with a reinforcing rib extending to the stopper.
Preferably, a sealing ring for sealing a gap between the upper end surface of the lower shell and the lower end surface of the stop block is arranged between the upper end surface of the lower shell and the lower end surface of the stop block.
Preferably, the upper end face of the lower shell is provided with a circle of sealing groove, and the sealing ring is accommodated in the sealing groove and can be abutted against the lower end face of the stop block.
Preferably, the opposite sides of the lower shell extend outwards and horizontally to form a mounting block, and the mounting block is provided with a mounting hole.
The invention has the following beneficial effects:
when the product is buckled and assembled, the upper cover is clamped downwards by the attached arc surface, the excessive external supporting force caused by excessive clamping of the corner does not exist, the risk of cracking of the upper cover when four corners are pressed downwards in the assembling process does not exist, and the yield is 100% in the actual production;
in the pressing process, because no corner transition exists in the middle, the phenomenon that one corner is not pressed into the product and is clamped and deformed is avoided, and the yield is 100% in actual production.
Drawings
Fig. 1 is a schematic structural view showing an appearance of a connector mounting self-locking structure according to an embodiment of the present invention;
FIG. 2 is a schematic view of the connector shown in FIG. 1 with the cover removed from the self-clinching structure;

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
It should be noted that all the directional indicators (such as up, down, left, right, front, and rear …) in the embodiment of the present invention are only used to explain the relative position relationship between the components, the movement situation, etc. in a specific posture (as shown in the drawing), and if the specific posture is changed, the directional indicator is changed accordingly. Furthermore, the terms "mounted," "disposed," "provided," "connected," and "sleeved" are to be construed broadly. For example, it may be a fixed connection, a removable connection, or a unitary construction; can be a mechanical connection, or an electrical connection; may be directly connected, or indirectly connected through intervening media, or may be in internal communication between two devices, elements or components. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art as appropriate.
Referring to fig. 1, 2 and 3, the present invention provides a connector mounting self-locking structure, including an upper cover 10 and a lower shell 20, wherein a plurality of bayonets 11 are disposed on an outer peripheral side of an opening of the upper cover 10, a locking block 21 is disposed on an outer peripheral side of an opening of the lower shell 20, the locking block 21 is engaged with the bayonets 11 to realize locking, an outer surface of the locking block 21 is an arc surface 211 with a size of R10, and a bottom of the locking block 21 is a horizontal surface 212. When the product is buckled and assembled, the arc surface 211 attached to the upper cover 10 is clamped downwards, the excessive external supporting force caused by excessive clamping of the corner does not exist, the risk of cracking of the upper cover when four corners are pressed downwards in the assembling process does not exist, and the yield is 100% in actual production; in the pressing process, because no corner transition exists in the middle, the phenomenon that one corner is not pressed into the product and is clamped and deformed is avoided, and the yield is 100% in actual production.
The upper cover 10 comprises a first cover body 12, a circle of stop block 13 is horizontally extended outwards from the opening end face of the first cover body 12, the stop block 13 vertically extends downwards to form a circle to surround the shell 14, the bayonet 11 is arranged on the surrounding shell 14, the outer side wall of the first cover body 12 is provided with a reinforcing rib 15 extending to the stop block 13, the strength and the rigidity of the upper cover 10 can be enhanced through the reinforcing rib 15, and under the condition that the wall thickness of the first cover body 12 is not increased, the material consumption is saved, the weight is reduced, and the cost is reduced.
