Description

Technical Field

[0001] This utility model relates to the technical field of connectors, and in particular to a novel through-wall connector. Background Technology

[0002] Connectors, also known domestically as plugs, sockets, or connectors, generally refer to electrical connectors. They are devices that connect two active devices to transmit current or signals.

[0003] While the existing connectors can meet the usage requirements, they still have certain structural shortcomings. Please refer to the attached instruction manual. Figure 1 An existing through-wall connector shown includes a housing A1, multiple terminals A2 inserted into the housing, multiple bolts A3, and multiple bottom covers A4. The lower ends of the multiple bolts pass through the through holes on the multiple terminals and extend downwards. The multiple bottom covers are disposed above the multiple bolts and snap into the housing to prevent the bolts from coming off. Since there are multiple bottom covers, they need to be installed one by one during assembly, which makes the connector assembly time-consuming and inefficient. Utility Model Content

[0004] In order to overcome the existing technical defects, the purpose of this utility model is to provide a new type of through-wall connector to solve the above-mentioned technical problems.

[0005] The technical solution adopted by this utility model to solve the technical problem is as follows:

[0006] According to one aspect of this utility model, a novel through-wall connector is designed, comprising: a housing, multiple terminals, multiple bolts, and a cover plate. The housing is provided with a connection hole and multiple insertion holes for inserting the screw heads of the bolts and restricting their rotation. The multiple terminals are respectively inserted into the housing through mounting holes at the left end of the housing, and the right ends of the terminals extend to the lower or right side of the insertion holes. The lower ends of the multiple bolts pass through the through holes at the right ends of the multiple terminals and extend downwards. The screw heads of the bolts are placed in the insertion holes. The bottom of the cover plate is provided with a buckle. When the buckle is inserted into the connection hole and engages with the buckle groove on the side wall of the connection hole, the cover plate blocks all insertion holes.

[0007] By adopting the above technical solution, a cover plate that can block all insertion holes is set, and a buckle that engages with the inner wall of the connection hole is set on the cover plate. When the cover plate is engaged with the buckle and the buckle, the cover plate can block all insertion holes and prevent the bolts from coming off. Compared with the connection structure that uses multiple bottom covers to engage with the housing to restrict the bolts, this connector is simpler to assemble, saves time, and can improve assembly efficiency.

[0008] To better address the aforementioned technical deficiencies, this utility model also offers a superior technical solution:

[0009] In some embodiments, each of the insertion holes has a first welding protrusion on its upper periphery that contacts the cover plate. In existing connectors, after the bottom cover and housing are snapped together, adhesive is applied to the periphery of the bottom cover to strengthen the connection. Multiple bottom covers require multiple applications of adhesive, impacting production efficiency. Furthermore, adhesive leakage during application can easily cause product contamination, requiring rework or rendering the product unusable. This technology addresses this by providing a first welding protrusion on the upper periphery of the insertion hole in the housing that contacts the cover plate. After the cover plate is attached to the housing, multiple first welding protrusions can be welded to the cover plate simultaneously using ultrasonic welding equipment. Using laser welding not only improves the connection strength but also increases production efficiency.

[0010] In some embodiments, each of the connecting holes is provided with a second welding protrusion in the shape of a U-shape that contacts the cover plate, and the two ends of the second welding protrusion are connected to the first welding protrusion.

[0011] In some embodiments, the first welding protrusion is a quadrilateral, hexagonal, or circular structure.

[0012] In some embodiments, each insertion hole has a connecting hole on its left and right sides, and the number of clips is the same as the number of connecting holes. This provides a more secure fixation for the cover plate. Attached Figure Description

After the cover plate 4 is snapped into the housing 1, the second welding protrusion 15 contacts the cover plate 4.

[0031] The first welding protrusion 14 and the second welding protrusion 15 contact the cover plate 4 to facilitate subsequent welding of the two together using ultrasonic welding equipment.

[0032] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
