Referring to
This embodiment sequentially connects the ground wires 22 in individual wires 2 on the connector in series, then adds the metal partition plate 3 to separate two adjacent groups of the wires 2 via the spacers 31 on the metal partition plate 3 and connect the spacers 31 to the ground wires 22, and separates any group of the wires 2 in a closed channel composed of the spacer 31 and the ground wire 22, such that signal dispersion is prevented on the wires 2, signal interference is avoided between the wires 2, and the stability of signal transmission is ensured.
Specifically, in this embodiment, the wire 2 comprises two signal wires 21 and two ground wires 22, the two signal wires 21 and the two ground wires 22 are separated by an insulating medium 23, and the two signal wires 21 are respectively connected to elastic pieces 24 that are connected to a PCB motherboard 5. The two signal wires 21 of the wire 2 are wrapped into a whole through the insulating medium 23, the two ground wires 22 are then arranged outside the insulating medium 23, the two ground wires 22 are stacked and distributed on both sides of the wire 2, and the wire 2 is mounted on the connector housing 1, and then the elastic pieces 24 are respectively connected to ends that are of the signal wires 21 and that extend out of the connector housing 1, to facilitate the connection between the connector and the PCB motherboard 5. Further, in this embodiment, the wires 2 are arranged in a straight line, two rows of the wires 2 are arranged on the connector housing 1, and the ground wires 22 in two adjacent groups of the wires 2 are connected in series; the metal partition plate 3 is then added, and a plurality of spacers 31 are arranged on the metal partition plate 3 in the length direction of the metal partition plate; after the metal partition plate 3 is mounted, the spacers 31 are respectively distributed between two adjacent wires 2 to separate the two adjacent wires 2; and meanwhile, the spacers 31 are further connected to the ground wires 22. In this way, the spacers 31 are conducted with the ground wires 22 during use to form a closed channel, and any of the wires 2 is distributed in a respective channel, such that signals can be enclosed in the channel, signal dispersion is effectively avoided on the signal wire 21, and therefore signal interference is avoided between adjacent wires 2, and the stability of signal transmission is ensured.
Further, the metal partition plate 3 is provided as a copper or stainless steel one-piece molded structure. It should be noted that, in order to ensure the metal partition plate is conducted with the ground wire 22 to form a closed channel, the partition plate is made of a metal material. As a preferred embodiment, a copper or stainless steel material may be adopted in this embodiment to facilitate production and ensure a more stable structure.
Further, the connector further comprises an insulating protective sleeve 4, and the insulating protective sleeve 4 covers ends of the wires 2. To improve the mounting performance in use, an insulating protective sleeve 4 can be added at ends of the wires 2 for insulation protection. In this embodiment, after the insulating protective sleeve 4 is added, the insulating protective sleeve 4 is first sleeved at the ends of the wires 2 when being mounted to wrap the wires 2, and in order to ensure the formation of the closed channel, the insulating protective sleeve 4 is then provided with a slot 41 for the spacer 31 to pass through. In this way, after the metal partition plate 3 is mounted on the insulating protective sleeve 4, the spacer 31 can correspondingly pass through the slot 41 to be conducted with the ground wire 22, which allows for a more stable and safer structure while preventing signal interference.
Further, the insulating protective sleeve 4 is provided as a plastic one-piece molded structure. The plastic material is of a certain elasticity, which allows the insulating protective sleeve 4 to be tightly wrapped outside the wire 2 and function as a buffer protection for the wire 2. Meanwhile, the plastic one-piece molding manufacturing process is simpler, and has a high manufacturing efficiency and a lower cost.
Further, one end of the metal partition plate 3 is provided with a pressing sheet 32 for pressing the insulating protective sleeve 4 against the connector housing 1, and the other end of the metal partition plate 3 is welded to the connector housing 1. It should be noted that, in order to prevent the insulating protective sleeve 4 from falling off from the connector, in this embodiment, a pressing sheet 32 is added at one end of the metal partition plate 3, and after the metal partition plate 3 is mounted in place, the pressing sheet 32 can apply a downward pressing force from one end of the insulating protective sleeve 4 to press the insulating protective sleeve 4 against the connector housing 1. Correspondingly, one end that is of the metal partition plate 3 and that is symmetrical to the pressing sheet 32 is welded on the connector housing 1 to fix the metal spacer 31, and effectively prevent the insulating protective sleeve 4 from falling off, thereby improving the structural stability.
