Board to board connector

The present invention provides a board-to-board connector, in particular, the plug connector can be inserted obliquely into the corresponding fitting portion of the socket connector, and the body is pressed down to make the buckle portion buckle. Don't get stuck in the buckle groove of the buckle part, and then block the block into the limit groove to make the horizontal limit block, so that the assembly is simple and the cost is lower.

According to the rapid development of electronic technology and multimedia information, electronic devices such as computers, notebook computers, tablet computers, and mobile devices (MIDs) have become commonplace in all corners of society, and tend to be light, thin, short, and small. Easy to carry and speed up in computing and transmission speed. Therefore, in order to reduce the size of various electronic devices, electronic components with different functions inside the electronic device need to be small and precise, and the overall structural strength needs to be strengthened to meet the current situation. development trend.

Moreover, in order to provide sufficient brightness and illumination effect of the electronic device, the human eye can clearly see the image displayed on the screen, and the manufacturer introduces the light guide plate and the light source technology inside the body or the screen, and develops a light-emitting diode. The backlight module of the body (LED) enables the light generated by the light-emitting diode to be projected onto the screen to form a backlight effect, and the backlight module generally integrates a plurality of light-emitting diodes on the back plate to form an LED. a light bar, and the plurality of through holes separated by a distance from the back plate and the corresponding protrusions on the inner substrate of the body are respectively engaged with each other, and then two adjacent The LED strips are electrically connected in series by means of connectors on the ends of the backboard, and the length of the assembly of the LED strips can be expanded according to the requirements of the structural design.

However, as the display screen size of the electronic device tends to be thinner and narrower, the space for the installation and utilization of the LED light bar of the backlight module tends to be narrower, and the two phases are opposite each other. The adjacent LED strips are more difficult to connect and fix the connectors to each other, and the general LED strips usually use the board-to-board connectors, the wire-to-board connectors or the circuit terminal connectors to be mated, and The pulse width modulation signal transmitted by the controller of the driving circuit drives the light emitting diode through the circuit of the connector and the back board to obtain the desired color and brightness, but the LED light bar has a space position limitation, Most of the board-to-board connectors can only be docked by horizontal plugging or vertical pressing, or they can be docked by small angle oblique insertion, so the direction of board-to-board connector insertion and removal will be limited. Restrictions, but because today's electronic devices are demanding modular production and capacity requirements, such board-to-board connector assembly processes are difficult and time-consuming, resulting in large assembly costs. Raise, that is yet to be studied are anxious to engage in this industry, where the direction of improvement.

Therefore, in view of the above-mentioned problems and shortcomings, the new creators have collected such relevant materials through various evaluations and considerations, and have used the trial and modification of many years of R&D experience in this industry to design such board-to-board connections. The new type of device was born.

The main purpose of the present invention is that the socket connector has a plurality of conductive terminals positioned on the front abutting portion of the base, and a fitting portion is disposed adjacent to the butting portion on the two sides of the base, and two sides of the front side of the butt portion There is a buckle portion with a buckle groove and a limit slot longitudinally disposed at a position behind the buckle portion. When the plug connector is inserted obliquely into the socket at the insertion portion at the front side of the side wall of the body When the corresponding fitting portion is connected to the connector, the body can be rotated to the horizontal position, and the buckle portions of the two side walls of the body are respectively engaged with the buckles of the fastening portion by the buckles, and The longitudinal blocking block on the buckle portion extends into the limiting slot to block the horizontal direction, and the abutting portion of the base is embedded in the recessed space between the front bottom surface of the main body and the two side walls. After that, the plurality of docking terminals positioned inside the body can be electrically connected to the conductive terminals, thereby achieving the advantages of simple assembly, improved production efficiency, and lower cost.

The second purpose of the creation is that when the plug connector is docked on the socket connector, the blocking block of the buckle portion can be inserted into the limiting slot of the base with the body rotating downward, and blocked. The block is limited to the horizontal limit blocking position in the limiting slot to prevent the socket connector and the plug connector from being improperly detached by the external force, and the docking portion of the body and the base can be properly translated after being butted. Margin, even if the displacement between the plug connector and the socket connector is small, it can maintain a good electrical connection effect.

Another purpose of the present invention is that the socket connector and the plug connector are respectively applied to the surface of the circuit board of the adjacent LED strip of the backlight module, and the LED strip is further mounted on the substrate inside the body of the electronic device. After the plug connector is mated to the socket connector of the circuit board at a large angle obliquely with the other circuit board, the other circuit board can be abutted on the surface of the substrate, and the positioning posts of the substrate are respectively passed through the other In the limiting hole of a circuit board, in order to facilitate the assembly of the plurality of LED light strips on the substrate at appropriate positions, it is possible to effectively save the assembly of the LED light strips according to the requirements of modular production and productivity. Working hours make the cost of overall assembly even lower.
