Description

Technical Field

[0001] The utility model relates to the technical field of electronic device accessories, in particular to a data cable connector. Background Art

[0002] For the Lightning plug dedicated to power banks, in order to achieve the automatic wake-up function, when the plug is not inserted into the mobile phone, the CC line should remain suspended and not be occupied (there is a 5.1K pull-down on the CC line or a pull-down inside the chip). If the CC line is not suspended, it will cause the power bank to not wake up and charge the mobile phone after the power bank goes into sleep when the mobile phone is plugged in again. The Lightning plug dedicated to power banks connects the 5.1K pull-down line or the chip ground on the CC line to the outer shell. When the plug is not inserted into the mobile phone, the outer shell is suspended and the CC pin is also suspended. When the plug is inserted into the mobile phone, the outer shell is conducted to GND through the female socket of the mobile phone, and the CC line is connected to GND through the outer shell and the female socket of the mobile phone, waking up the power bank to charge the mobile phone and achieving the automatic wake-up function.

[0003] To achieve the above function, the outer shell of the Lightning plug must be well connected to the PCB circuit. The existing technology is to apply solder paste on the pads on both sides of the PCB. After passing through the furnace, the solder paste solidifies and piles up to a certain height. The thickness of the solder paste on the PCB board is greater than the thickness of the inner wall of the outer shell. After the PCB board is inserted into the outer shell, the solder paste deforms under force and generates a certain bonding force with the inner wall of the outer shell. Through this bonding force, the PCB pads are electrically connected to the inner wall of the outer shell.

[0004] The disadvantages of this technology are as follows:

[0005] 1. To ensure good connection between the PCB pads and the outer shell, the height of the solder paste must be within the required range. If the height of the solder paste is not well controlled, it will cause functional hidden dangers in the product;

[0006] 2. For the qualified products after production and testing of the Lightning plug, during the wire processing and production, due to the mold tolerance, the outer shell will be extruded by the mold, causing the solder paste on the PCB pads to be pressed down and not rebound, resulting in a smaller bonding force between the solder paste and the outer shell, causing poor contact and functional hidden dangers;

[0007] 3. During use, if the outer shell of the plug is extruded and deformed, it is easy to cause poor contact between the outer shell and the PCB, resulting in functional hidden dangers. Summary of the Invention

[0008] The utility model provides a data cable connector to solve the above-mentioned existing technical problems.

[0009] The technical solution of the utility model is realized as follows:

[0010] A data cable connector includes a PCB board. A housing is sleeved on the PCB board. First connection parts for bearing solder and the inner wall of the housing are arranged at positions on the PCB board near both sides. A second connection part for bearing solder is also arranged on the PCB board. One end of the housing is connected to the PCB board through solder.

[0011] Further, the PCB board includes a wiring part and a gold finger mounting part. The first connection parts are arranged on both sides of the gold finger mounting part. The housing includes a fixing part and a potting part. Gold finger reserved openings are reserved on both sides of the fixing part.

[0012] Further, the wiring part and the gold finger mounting part are integrally arranged. A through injection port is formed on the gold finger mounting part.

[0013] Further, the gold finger mounting part is inserted and mounted in the fixing part. A gap is reserved between the wiring part and the inner wall of the potting part.

[0014] Further, the first connection parts are arranged on both sides of the gold finger mounting part. Solder for connecting the inner wall of the fixing part is arranged on the first connection parts.

[0015] Further, the position of the first connection parts is arranged on the surface of the gold finger mounting part at least in one direction.

[0016] Further, the position of the second connection part corresponds to the position of the potting part. Solder for connecting the wiring part and the potting part is arranged on the second connection part.

[0017] Further, the injection port is an opening with a corner.

[0018] Compared with the prior art, the utility model has the following beneficial effects:

[0019] In the utility model, by adding a second connection part for bearing solder at the position corresponding to the potting part of the housing on the wiring part of the PCB board, and placing solder on the second connection part to weld between the wiring part and the potting part, the connection stability between the housing and the PCB board is further improved. The solder on the second connection part fills the gap between the wiring part and the potting part, and at the same time overflows and surrounds a part of the potting part, forming a stable connection state with the potting part. Even if the housing is extruded and deformed during the production process, there will be no contact failure. It solves the problem that during the processing and production, due to the mold tolerance, the housing will be extruded by the mold, the solder on the PCB pad will not rebound after being pressed down, resulting in a smaller bonding force between the solder and the housing, causing contact failure and functional hidden dangers.

[0020] Moreover, this method does not have strict requirements for the solder height, so it can prevent the situation where functional hidden dangers occur in the product due to poor control of the solder height during the production process, solving the problem in the prior art that if the solder paste height between the PCB board and the housing is not well controlled, it will cause functional hidden dangers in the whole batch of products;

[0021] At the same time, during the use process, if the fixing part of the housing is squeezed and deformed, affecting the contact between the gold finger installation part and the housing, since the solder on the second connecting part firmly connects the encapsulation part and the wiring part, the deformation of the fixing part will not affect the overall function, solving the problem in the prior art that the housing of the connector is squeezed and deformed, resulting in poor contact between the housing and the PCB board and causing functional hidden dangers.
