Technical Field
[0001] This utility model relates to the field of board-end connectors, and in particular to a structurally enhanced board-end connector. Background Technology
[0002] Electronic connectors, also known as circuit connectors or electrical connectors, are conductor devices that bridge two conductors in a circuit, allowing current or signals to flow from one conductor to the other. An electronic connector is an electrical system that provides a separable interface for connecting two electronic systems. Simply put, a connector is a component used to complete the electrical connection between circuits or electronic devices; it is the bridge between the two. Examples include power plugs / sockets, IC sockets, telephone line plugs, etc.
[0003] Electronic connectors are widely used in various electrical circuits to connect or disconnect current or signals. This connection can be temporary and easily plugged in and out, or it can be a permanent connection between electrical equipment or wires. Electronic connectors are generally divided into two categories: female connectors and male connectors. Female connectors and male connectors are used in sets to connect and connect the circuit to achieve data transmission. Board-end connectors are a type of female connector.
[0004] Current board-end connectors typically consist of an insulating body, multiple terminals, and two retaining plates. The terminals are housed within the insulating body, which has protrusions on both sides. The retaining plates have slots for mounting the two plates onto the left and right sides of the insulating body. The protrusions engage with the slots to secure the connector. While this structure is simple, it lacks robustness. During use, lateral forces can cause the protrusions to detach from the slots, leading to loosening of the retaining plates. This can result in deformation or even breakage of the terminal solder joints, damaging the product, causing poor contact, unstable signal transmission, and disrupting normal operation. This results in a poor user experience, generally lower product quality, and a lack of competitiveness, failing to meet current needs. Therefore, it is necessary to research a new technical solution to improve current board-end connectors. Utility Model Content
[0005] In view of this, the present invention addresses the deficiencies of the existing technology and its main objective is to provide a structurally enhanced board-end connector. This effectively solves the problems of existing board-end connectors, such as insufficient structural stability, easy detachment of the protrusion from the slot when subjected to lateral external forces during use, resulting in loosening of the fixing piece, deformation or even breakage of the terminal solder joint, damage to the product, poor contact, unstable signal transmission, affecting normal product operation, poor user experience, and generally low product quality, making the product less competitive.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A structurally reinforced board-end connector includes an insulating body, multiple terminals, and two fixing plates. The insulating body has a forward-facing insertion cavity. Positioning grooves are provided on both sides of the insulating body. Each positioning groove includes a mounting groove and multiple through grooves. These through grooves are arranged side-by-side and spaced apart below the mounting groove and all communicate with it. A positioning block is provided between two adjacent through grooves. The upper end of the positioning block has guide angles on both its front and rear sides for guiding the fixing plates during installation. This ensures that the fixing plates are properly inserted into the positioning grooves. Even if the fixing plates are slightly tilted during insertion, they can still be guided and effectively inserted into place, preventing product damage caused by incorrect insertion. Installation is convenient. It is quick and convenient for production; the multiple terminals are set in the insulating body, the contact parts of the multiple terminals extend into the insertion cavity, and the welding parts of the multiple terminals extend out of the insulating body; the two fixing pieces are respectively set in the corresponding positioning grooves, each fixing piece includes a main body and multiple positioning parts extending downward from the main body. The main body is set in the mounting groove, and the multiple positioning parts are respectively set in the corresponding through grooves. Each positioning part has locking points on the front and rear sides. The locking points abut against the inner wall of the through groove. The interference fit between the locking points and the through groove can effectively enhance the stability of the connection structure between the fixing piece and the insulating body, generate a stable holding force after assembly, prevent loosening and failure, and improve product quality.
[0008] As a preferred embodiment, the terminal includes the contact portion, the fixing portion, and the welding portion integrally formed and connected in sequence. The fixing portion is embedded in the insulating body, and fixing protrusions are provided on the left and right sides of the fixing portion. The two fixing protrusions are embedded in the insulating body, which effectively enhances the stability of the connection structure between the terminal and the insulating body, generates a stable holding force, and prevents loosening and failure.
[0009] As a preferred embodiment, the fixing protrusion has a triangular structure, which further enhances the stability of the connection structure between the terminal and the insulating body.
[0010] As a preferred option, the terminal has a Z-shaped structure, which meets the user's design requirements for a horizontal mounting plate.
[0011] As a preferred embodiment, two locking points are provided on the front and rear sides of the positioning part to further enhance the stability of the connection structure between the fixing piece and the insulating body. The locking points can also be configured in other numbers.
[0012] As a preferred embodiment, the bottom surfaces of the multiple positioning parts are flush with the bottom surfaces of the multiple terminal welding parts. After the product is welded to the PCB board, the multiple positioning parts and the PCB board form a stable structure, and the multiple terminal welding parts and the PCB board form a stable structure, simultaneously generating a stable holding force. This prevents the product from easily loosening in harsh vibration environments, which could lead to functional failure and greatly improves the quality of the product.
[0013] As a preferred embodiment, each fixing piece includes three positioning parts, all of which extend downward from the main body. Each positioning groove includes three through grooves, and the three positioning parts are respectively disposed in the corresponding through grooves. The cooperation between the positioning grooves and the three positioning parts can form a very stable connection structure.
[0014] As a preferred embodiment, the rear side of the insulating body is provided with multiple limiting grooves. The multiple terminals are respectively set in the corresponding limiting grooves to cooperate in limiting the position, which can protect the correct position of the terminals, prevent the welding part of the terminals from being skewed to the left or right, thus preventing welding defects, ensuring the welding quality of the terminals, and bringing convenience to production.
[0015] As a preferred embodiment, a guide groove is provided on the inner wall of the insertion cavity. This guide groove is used to guide and cooperate with the external connector, making the mating of the external connector and the board-end connector smoother, facilitating and speeding up assembly, and effectively enhancing the stability of the connection structure.
[0016] As a preferred embodiment, a guide block is provided on the inner wall of the insertion cavity. The guide block is used to guide and cooperate with the external connector, making the mating of the external connector and the board end connector smoother, facilitating and speeding up assembly, and effectively enhancing the stability of the connection structure.
[0017] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:
[0018] By providing positioning grooves on both sides of the insulating body, each positioning groove includes a mounting groove and multiple through grooves. These through grooves are arranged side-by-side and spaced apart below the mounting groove, all communicating with it. A positioning block is provided between adjacent through grooves. The upper end of each positioning block has guide angles on its front and rear sides for guiding the fixing pieces during installation. Two fixing pieces are respectively placed in their corresponding positioning grooves. Each fixing piece includes a main body and multiple positioning parts extending downwards from the main body. The main body is located in the mounting groove, and the multiple positioning parts are respectively located in their corresponding through grooves. Each positioning part has locking points on its front and rear sides, which abut against the inner wall of the through groove. This board-end connector structure effectively enhances the connection between the insulating body and the two fixing pieces. Stability: Because the fixing plates are inserted into the positioning slots from top to bottom, and the positioning parts of the two fixing plates are soldered to the PCB board, as are the soldering parts of multiple terminals, the product has better holding force. The overall connection structure with the PCB board is firm and reliable. Even under lateral external forces during use, the two fixing plates are not easy to loosen, preventing deformation or breakage of the terminal soldering parts, preventing product damage, ensuring good contact connection, improving signal transmission stability, ensuring normal product operation, improving user experience, improving product quality, and making the product more competitive. The guide angle setting allows the fixing plates to be inserted well into the positioning slots during assembly, making installation convenient and quick, bringing convenience to production and meeting current needs.
