Description

Technical Field

[0001] The utility model relates to a connecting wire component, in particular to a plastic shell. Background Art

[0002] Connectors have a wide range of applications, spanning various industries and fields, and are an indispensable part of modern society. They utilize the transmission principle of electrical signals along the wire to transmit data and power. Connectors typically consist of two parts: a connector and a conductor. The connector consists of a male and female end, connecting the cable to the device. The design and manufacturing quality of the connector can also affect transmission performance.

[0003] The connector includes a plastic shell and a wire clamp. The plastic shell includes a main body and a transparent part. The transparent part is used to display the working status of the internal electrical components and is also convenient for the external display of the internal indicator light. The existing fixing method between the main body and the transparent part is mostly fastened by multiple fasteners, and the clamping and fixing operation of the wire clamp also requires the use of fasteners. For plastic shells with compact structure, small size and thin wall thickness, more fasteners and threaded hole structures for fasteners will greatly occupy the internal space of the plastic shell, thereby reducing the convenience of internal installation of electrical components. In addition, the design structure with more threaded holes will greatly increase the mold production cost of the plastic shell and the design cost of the manual structure design. Therefore, based on the above problems, this improvement was born. Utility Model Content

[0004] The purpose of the utility model is to provide a plastic shell, which reduces the amount of fasteners used, thereby improving the convenience of subsequent installation of electrical components and reducing the production cost of the product, making it more practical.

[0006] By adopting this technical solution, a fastener is threadedly connected to the main body to synchronously apply torque to the wire clamp and the fixing assembly. The fastener drives the wire clamp toward the clamping channel, allowing the wire clamp to clamp the wire passing through the clamping channel and further secure the wire. The fixing assembly, in turn, drives the transparent portion, under the action of the matching structure, to limit the transparent portion to the first position, so that the transparent portion covers the installation opening, thereby simultaneously achieving the tightening operation of the transparent portion and the wire clamp. This structure reduces the number of fasteners used, thereby improving the convenience of subsequent electrical component installation and reducing the production cost of the product, making it more practical.

[0008] By adopting the above technical solution, the slide rail and the slide groove cooperate to realize the sliding of the transparent part so that it switches between the first position and the second position, thereby being driven by the fastener to achieve the purpose of covering the installation opening.

[0009] It is further configured as follows: a resisting surface is formed between the main body and the transparent part and is arranged around the outer periphery of the installation opening. The resisting surface is arranged at an angle so that the transparent part can press against each other along the sliding direction.

[0010] By adopting the above technical solution, the inclined opposing surfaces change the direction of force, so that the transparent part and the main body can be more tightly pressed together during the sliding process, thereby improving the sealing of the assembly.

[0011] It is further configured as follows: the fixing assembly includes a fixing frame and an embedding groove formed on the main body and the transparent part and for the fixing frame to be embedded in; the fastener passes through the fixing frame; and an extrusion structure is provided between the fixing frame and the embedding groove.

[0012] By adopting the above technical solution, the fastener passes through the fixing frame to drive the fixing frame to be inserted into the two embedding grooves, and the position of the fixing frame is positioned by the provided embedding grooves, ensuring that the fixing frame applies a stable pressing and fixing force to the transparent part to drive the transparent part to fix it in the first position.

[0013] It is further configured as follows: two fixing feet are formed on the fixing frame and are respectively inserted into the embedding grooves; the extrusion structure includes extrusion inclined surfaces formed on the two fixing feet and symmetrically arranged along the insertion direction of the fixing feet; and matching inclined surfaces are formed on the two embedding grooves and match the extrusion inclined surfaces; the extrusion inclined surfaces are gradually expanded along the symmetrical direction.

[0014] By adopting the above technical solution, the structure enables the fixing assembly to drive the transparent part to fix it in the first position, and at the same time, can apply a clamping and fixing extrusion force to both the transparent part and the main body to improve the tightness of the assembly of the two.

[0015] It is further configured as follows: comprising a through hole formed on the fixing frame for the fastener to pass through, the through hole and the fastener abutting against each other to form a sealing surface, and a sealing member for sealing the fastener and the main body is connected to the fixing frame.

[0016] By adopting the above technical solution, the sealing surface cooperates with the sealing member to achieve sealing between the fastener and the main body, which is used to isolate the installation cavity from the outside world to ensure the sealing of this position.

[0017] It is further configured as follows: the sealing member is an elastic sealing sleeve sleeved on the fastener, and two ends of the sealing sleeve respectively abut against the fixing frame and the main body.

[0018] By adopting the above technical solution, the sealing sleeve cooperates with the sealing surface to achieve the sealing function, which has a simple structure, is easy to install and has low cost.

[0019] In summary, the present invention has the following beneficial effects: the present invention reduces the amount of fasteners used, thereby improving the convenience of subsequent installation of electrical components and reducing the production cost of the product, making it more practical.
