Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a safety structure for connectors. Background Technology

[0002] In fields such as electronic equipment, power systems, and communication engineering, connectors are core components for achieving circuit conductivity, and their safety and stability directly determine the operational reliability of the entire system. Connectors typically consist of a fixed part, a mating part, conductive elements, and an insulating shell, transmitting current or signals through mating and unmating. In critical scenarios such as industrial control, automotive electronics, and medical devices, connectors not only need to ensure stable conductivity with low contact resistance but also must withstand the effects of complex environmental factors such as vibration, impact, dust, and moisture. Traditional connectors rely solely on simple fixation at both ends for their conductive pins, lacking effective support in the middle. When equipment is in a vibrating environment, the conductive pins are prone to shaking or bending, leading to poor contact with the metal housing. This manifests as signal transmission interruption, increased contact resistance, and even arcing, potentially causing equipment shutdown or fire in severe cases. Furthermore, traditional connector housings are often open or have simple snap-fit ​​structures, making it difficult to effectively prevent external dust and moisture. In humid environments, moisture can easily penetrate the connector, causing corrosion of metal components and a decline in insulation performance.

[0003] Traditional connectors have crude mating and positioning structures. Most rely solely on the dimensional fit between the insert and the housing for positioning, lacking guiding and supporting mechanisms. This makes them prone to misalignment during mating, causing the insert to bend or the housing to deform. Although some connectors have locking devices, the locking strength is insufficient, and they are easily disengaged under vibration or external pulling force. Utility Model Content

[0004] This invention solves the problems in related technologies and proposes a safety structure for connectors.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: A safety structure for a connector includes a fixing part and a plugging part. The fixing part includes a main shell part and an outer ring plate.

The plugging part is plugged and fixed in the main shell part, and a plurality of metal sleeves that cooperate with the conductive plug rods are fixedly installed in the plugging part. Protective covers are also sleeved and fixed on the outer sides of the plugging part and the main shell part.

[0006] As a preferred embodiment, the reinforcing seat includes a ring seat and a supporting corner plate. The ring seat is disposed on the inner side of the rear end face of the main shell, and the supporting corner plate is evenly disposed on the outer side of the ring seat. The ring seat, the supporting corner plate and the main shell are integrally formed.

[0007] As a preferred embodiment, the support frame includes an upright plate and an arc-shaped support plate that is fitted onto the conductive plug rod. The upright plate is fixedly installed on the inner side of the main shell, and the arc-shaped support plate is fixedly installed on one end of the upright plate.

[0008] As a preferred embodiment, the insertion part includes an outer cover plate and a core block, the core block being installed on the inner side of the outer cover plate, and the core block being integrally formed with the outer cover plate.

[0009] As a preferred embodiment, the outer cover plate is symmetrically provided with elastic retaining plates on both sides, the elastic retaining plates are integrally formed with the outer cover plate, and the outer side surface of the main shell is provided with a retaining groove corresponding to the elastic retaining plates.

[0010] As a preferred embodiment, the insert block is provided with a positioning groove corresponding to the upright plate, and an auxiliary inclined surface is provided at the inner end of the positioning groove.

[0011] As a preferred embodiment, the protective cover includes an outer cover plate and a curved plate, wherein the curved plate is installed at the upper and lower ends of the outer cover plate, and the curved plate is integrally formed with the outer cover plate.

[0012] Compared with existing technologies, the beneficial effects of this utility model are as follows: This application effectively supports the conductive plug rod through the reinforcing base and support frame, and the cooperation between the elastic retaining plate and the slot makes the connection of each component of the connector more secure, reducing contact problems caused by loosening or shaking, and improving the stability and reliability of the connector.

The main housing portion 11 and the outer ring plate 12 are preferably made of high-strength engineering plastics, such as polycarbonate (PC) or polyamide (PA), which have good mechanical and insulating properties, ensuring the structural strength and safety of the fixing portion 1. The conductive plug 2 is made of high-purity copper, such as T2 copper, which has good electrical and thermal conductivity. The metal casing 6 is made of copper, such as brass, to ensure good contact conductivity with the conductive plug 2. The reinforcing base 3 and support frame 4 can be made of the same engineering plastic as the main housing portion 11, manufactured using an integrated molding process to ensure structural stability.

The outer cover plate 71 can prevent external dust, moisture, etc. from entering the connector. The bent plate 72 is installed at both the upper and lower ends of the outer cover plate 71, which can further enhance the protective effect, prevent dust and moisture from entering from the upper and lower ends, provide comprehensive protection for the connector, and extend the service life of the connector.

[0026] In this embodiment, during actual installation, the conductive plug 2 is evenly installed in the main housing 11, and the reinforcing base 3 and support frame 4 are installed simultaneously. This ensures that the ring seat 31 and support corner plate 32 of the reinforcing base 3, and the upright plate 41 and arc-shaped support plate 42 of the support frame 4 are tightly connected to the main housing 11, providing good support for the conductive plug 2. The metal sleeve 6 is fixedly installed in the plug block 52, and then the plug block 52 and the outer cover plate 51 are integrally formed to create the plug-in part 5.
