Abstract
The invention discloses a plastic buckle connecting structure of an automobile ceiling lamp, which comprises a socket and a shell which are mutually clamped, wherein a group of clamping holes are formed in the shell, a group of buckles matched with the clamping holes are arranged on the socket, the clamping holes are square clamping holes, a connecting rib is arranged in the middle of the square clamping holes in the length direction, and a abdicating groove matched with the connecting rib is formed in the middle of each buckle. The invention can solve the problem that the position of the welding line is easy to crack when the clamping hole is injected, thereby improving the injection molding quality of the shell and being widely applied to the field of injection molding of automobile switch shells.
Description
Technical Field
The invention relates to the technical field of automobile switch processing, in particular to a plastic buckle connecting structure of an automobile ceiling lamp.
Background
Generally, the plastic buckle on the automobile ceiling lamp is simple in structure, a square fixing boss is adopted on the socket, and a square hole clamping hole is adopted on the shell, so that the connecting and fixing functions of the automobile ceiling lamp socket and the shell are realized. In the use, the square structure of the part clamping hole is found, and during injection molding, plastic fluid is gathered from the two sides of the clamping hole to the middle, so that the clamping hole structure is formed, a serious welding line can appear in the middle of the shell square hole during injection molding, and the assembly cannot be influenced by judging the size of the welding line by using no detection means in the production process. Therefore, in the product assembling process, the problem that the clamping holes of the shell are cracked at the position of the welding line often occurs, and the quality of the product is affected. Some clamping holes are not cracked in the assembling process, but are broken under the action of certain external force after being placed for a period of time or being assembled, so that the quality of the automobile dome lamp product is influenced.
Disclosure of Invention
The invention aims to provide a plastic buckle connecting structure of an automobile ceiling lamp, which solves the problems that the existing clamping hole is easy to crack and the clamping reliability is influenced.
The technical scheme adopted by the invention for solving the technical problems is as follows: the utility model provides an automobile ceiling lamp plastics buckle connection structure, includes socket and the shell of mutual joint, be provided with a set of card hole on the shell, be provided with a set of and block hole complex buckle on the socket, the card hole is square card hole, is provided with a splice bar in square card hole length direction's intermediate position, the intermediate position of buckle be provided with splice bar complex groove of stepping down.
In order to further reduce the deformation and cracking of the clamping hole, arc transition structures are arranged at four corners of the clamping hole.
Preferably, the width of the connecting rib is 0.8-1.2 mm.
Preferably, the thickness of the connecting rib is the same as that of the clamping hole.
The invention has the beneficial effects that: according to the invention, the connecting rib is additionally arranged at the middle position of the clamping hole, so that the problem that the shell is easy to crack at the position of the welding line can be well solved. Simultaneously, the circular arc transition structure in card hole can further avoid the card hole concentration of stress when moulding plastics, reduces the probability of card hole corner fracture to improve the quality and the qualification rate of shell.
The invention will be explained in more detail below with reference to the drawings and examples.
Drawings
Fig. 1 is a schematic perspective view of the housing of the present invention.
Fig. 2 is a schematic perspective view of the socket of the present invention.
Detailed Description
The embodiment, as shown in fig. 1, 2, a car dome lamp plastics buckle connection structure, socket 1 and shell 2 including mutual joint, be provided with a set of card hole 3 on the shell 2, be provided with a set of buckle 4 with card hole 3 complex on the socket 1, card hole 3 is square card hole, is provided with a splice bar 5 in square card hole length direction's intermediate position, the intermediate position of buckle 4 is provided with and connects 5 complex slots of stepping down 6 of muscle. The position of the connecting rib 5 coincides with the position of the welding line, and the welding line position forms a connecting rib 5 through the adjustment of the runner on the die, so that the problems of insufficient strength and easy cracking of the welding line position are solved. The four corners of the clamping hole 3 are provided with arc transition structures 31, so that the problem of cracking caused by stress concentration of a right-angle structure is avoided. Meanwhile, the width of the connecting rib 5 is preferably 0.8-1.2 mm, and the thickness of the connecting rib is the same as that of the clamping hole 3.
The invention is described above with reference to the accompanying drawings. It is to be understood that the specific implementations of the invention are not limited in this respect. Various insubstantial improvements are made by adopting the method conception and the technical scheme of the invention; the present invention is not limited to the above embodiments, and can be modified in various ways.
