Description

Video connector with pin solder joint inspection hole {VIDEO CONNECTOR WITH PIN SOLDER JOINT INSPECTION HOLES}

The present invention relates to the structure of a video connector. More specifically, the present invention is a solder joint between the pin and the circuit board of the connector, so that the operator on the production line can easily and quickly inspect the soldering state of the joint between each pin and the circuit board. It relates to the structure of the DisplayPort connector that is completely exposed through the inspection hole.

DisplayPort (DP) is a set of connector specifications jointly developed by a personal computer and chip manufacturer. The DP specification is recognized as a digital video interface standard by the Video Electronics Standards Association (VESA) and can be used without certification or royalty. These interface standards mainly apply to the transmission of video signals between a video source (eg, a computer) and a display device, but also support audio, Universal Serial Bus (USB), and other types of data. The DP interface standard is designed to replace these conventional interface standards as Video Graphics Array (VGA), Digital Visual Interface (DVI), and FPD-Link (or Low-Voltage Differential Signaling (LVDS)), and can be used with active or passive adapters. It is backward compatible with HDMI (High-Definition Multimedia Interface), DVI and other conventional interface standards. In particular, the Mini DisplayPort (Mini DP) connector is currently widely used to connect desktop and laptop computers, typically having a Mini DP interface, to a conventional analog VGA display or display device having the same interface as the projector has. Equipment manufacturers mainly use Mini DP connectors to help increase the flexibility of use of the end product and promote Mini DP as a high-performance digital display interface. In general, there is a market demand for a specific product or device because a product or device has the specific characteristics required. The Mini DP connector is preferred by equipment manufacturers and the general public because it makes the cable adapter smaller, more energy efficient, less expensive, and more reliable. Therefore, Mini DP connectors not only energize the connector industry, but also create new market opportunities.

Since the adapter can be integrated into the Mini DP connector and thus can be provided between the corresponding computer and display device, this convenient design makes it easier to apply the adapter to a wider variety of conventional computer and display devices; In other words, the adapter integrated into the Mini DP connector can be adapted to a wider variety of connection environments than conventionally allowed. The Mini DP connector can also be embedded in a laptop computer or extension station to serve as a connection interface. In summary, the Mini DP connector is easily adaptable to many conventional interface standards due to the following features:

1. The Mini DP connector supports a 20-pin DP interface and can therefore be used for a number of compatible electronic devices. This undoubtedly expands the service of the connector provider and creates more development opportunities for the connector business.

2. The Mini DP connector supports a maximum bandwidth of 10.8 Gbps, as well as a transmission interface using 8-bit to 10-bit color pixels. These two functions can meet the needs of most consumers who want to use high-speed networks in their daily lives.

3. The Mini DP connector is hot-pluggable. That is, with the aid of appropriate software, a Mini DP connector, or more specifically a hot pluggable peripheral with a connector installed, does not need to cut off the power supply to the device and consequently the device or peripheral will be burned. It may be connected to and disconnected from a device (eg, a computer) during operation. Being hot pluggable also means that the Mini DP connector can detect and use new devices at once. Undoubtedly, the above-described features also make the Mini DP connector very flexible to use and very convenient to use.

In addition, the high adaptability and consequent convenience of the Mini DP connector creates a wide range of equipment upgrade possibilities for the general public as well as equipment manufacturers. In this respect and inspired by it, the inventors of the present invention believe that, since the purchase of equipment manufacturers should lead to more demand in the future, DP connector designers and manufacturers are not only effective in meeting a single order and their sales, but also in the future. We believe that attention should be paid to the adaptability of the DP connector in equipment upgrades. Therefore, major connector design and manufacturing companies have an important problem to improve the adaptability, yield, and upgradeability of the DP connector, and the same problem is solved by the present invention.

In view of the shortcomings of the conventional DP connector's complex manufacturing process, the inventors of the present invention have spent years of practical experience in the development, design, and manufacturing of various video connectors in extensive research, continuous improvement, and repeated testing. And finally succeeded in designing a video connector with pin solder joint inspection holes. The pin solder joint inspection hole allows the video connector manufacturer to quickly and easily inspect the soldering condition of the joint between the video connector's circuit board and each pin, so that each pin is connected by a video connector (e.g. , Computer and display device) is intended to ensure that it is properly connected and maintained to the circuit board to produce an optimal video transmission effect.

Pin solder joint inspection holes are formed in each of the upper side and the bottom side of the insulating plastic body. The front insertion hole, the pin solder joint inspection hole, and the rear insertion hole communicate individually with the positioning space. Each of the upper side and the lower side of the circuit board is provided with a plurality of pin contacts adjacent to the front edge of the circuit board. The pin contacts are electrically connected to the circuit on the circuit board. The contact terminal at the rear end of each pin is soldered to the corresponding pin contact. Once the contact terminals at the rear end of the pins are soldered to the respective pin contacts, the circuit board and the pins together form a configuration that matches the positioning space. This allows the circuit board and the pins soldered thereto to pass through the rear insertion hole until the circuit board is firmly positioned within the positioning space, and the contact terminals at the front end of each pin are positioned and engaged in the corresponding pin engagement groove.

In addition, an engaging hook adjacent to the front end is provided on the upper side of each elastic engaging member to protrude. When a video connector is plugged into or connected to a corresponding video connector socket, the mating hook is electrically connected in a fixed manner in which the video connector and video connector socket can reliably transmit video signals to each other, and not easily separated from each other. Each and securely hooked or mated to a corresponding mating part in the video connector socket to ensure that it does not cause an interruption in signal transmission when shaken.

Another object of the present invention is to provide the above-described video connector having the following additional features: On the upper side of each elastic coupling member, a release key adjacent to the rear end is provided protruding. When it is required to unplug or disconnect the video connector from the video connector socket, the user only needs to press the release key to push the release key toward the rear end of the video connector, and the mating hooks each have a corresponding It will be released from the mating portion to allow the video connector to be disconnected from the video connector socket.
