Description

Technical Field

[0001] The utility model relates to the technical field of USB, in particular to a single-row upright connector which is easy to position. Background Art

[0002] With the development of science and technology, more and more electronic and electrical equipment appear in people's daily life, especially in electronic equipment. Almost all kinds of electronic equipment need connectors, such as the most common USB connector. Nowadays, the most commonly used connectors are mostly horizontal, but a problem that people often encounter in the process of using such connectors is that the plug-in and unplug space is inconvenient. In some places, the plug-in and unplug space reserved for connectors is relatively small, and there is not enough space for horizontal placement of connectors. At this time, many people think of changing the horizontal vertical connector to a vertical one, which can well solve the problem of insufficient component placement space, that is, the connector plug end is horizontal with the transmission line, and meet the needs of electronic signal transmission in special occasions.

[0003] After searching, the Chinese publication number is: CN208849100U discloses an upright connector that supports high-frequency transmission and occupies a small space on the PCB board. The utility model discloses an upright connector that supports high-frequency transmission and occupies a small space on the PCB board. The utility model adopts an insertion port that is 180 degrees to the soldering tin foot and can stand vertically on the interface soldered on the PCBA, thereby solving the problems of plug-in and unplugging and board layout space limitations in a small space. Through structural optimization, the minimum terminal bending structure and the design of double-row symmetrical wide and narrow PINs are used to obtain more excellent transmission and anti-interference performance. The innovative pin symmetrical arrangement and distribution structure (two rows of SMT feet) is conducive to the distribution of pads and meets the process of SMT patch reflow soldering. The design of double-row symmetrical SMD pins can be simple on the single-sided wiring of the PCB board and is conducive to the application of ultra-thin products. The MID-plate is extended to the outer shell welding foot and the SMD board design is adopted to obtain better high-frequency characteristic impedance. The design adopts a symmetrical and movable positioning and fixing shielding shell, which can solve the problem of inconvenience in checking coplanarity in the process and better shielding effect after board welding.

[0004] However, since most SMT components require delicate installation, workers need to undergo a long period of training and practice before they can start working. This will result in a long training cycle for the workers, which can easily lead to an imbalance between staff turnover and staff replenishment. Most single-row upright SMT components lack small holes for installation in comparison with the PCB board, so it is easy to cause errors in the installation position of the SMT components during installation, resulting in positional deviation. In view of this, we propose a single-row upright connector that is easy to position. Utility Model Content

[0029] Embodiment 2

[0030] See also Figure 4-Figure 6On the basis of the first embodiment, the utility model provides a technical solution: preferably, a limiting mechanism 11 is provided on the right surface of the rib 7, the limiting mechanism 11 includes a limiting groove 111, the right surface of the rib 7 is provided with a limiting groove 111, the inner surface of the limiting groove 111 is fixedly connected with a baffle 112, the front surface of the baffle 112 is rotatably connected with a stop plate 113, the left surface of the stop plate 113 is fixedly connected with a connecting block 14, the inner surface of the limiting groove 111 is penetrated by an elastic slide bar 15 and is slidably connected with the elastic slide bar 15, and the elastic slide bar 15 is hinged to one end of the bracket 16, The connecting block 14 is hinged to the other end of the bracket 16, and the elastic slide bar 15 is composed of a spring and a slide bar. The slide bar is fixed to one end of the spring, and the other end of the spring is fixed to the inner surface of the limiting groove 111. The elasticity of the spring supports the abutment plate 113, so that the upper end of the abutment plate 113 always has an outward force. When the single-row upright SMT is installed on the PCB board, the friction between the SMT and the PCB board can be effectively increased. Before the single-row upright SMT is not soldered, the single-row upright SMT can also be kept at the installation point without deviation, so that workers can It is more convenient to install. One end of the butt plate 113 is rotatably connected to the baffle 112, and the other end of the butt plate 113 is provided with a slide groove 17 in a linear array. The inner surface of the slide groove 17 is slidably connected with a butt block 18, and the lower surface of the butt block 18 is fixedly connected with an elastic telescopic rod 19. The elastic telescopic rod 19 passes through the inner surface of the slide groove 17 and is slidably connected with the slide groove 17. The elastic telescopic rod 19 is composed of a spring and a telescopic rod. One end of the spring is fixedly connected to the butt block 18, and the other end is fixedly connected to the telescopic rod. Through the elasticity of the spring, the butt block 18 always maintains a force protruding outward, and at the same time When the butt block 18 and the slide groove 17 have a certain gap, the friction between the butt plate 113 and the PCB board is increased, and the SMT is more stable. The upper and lower ends of the butt plate 113 are rounded, and the upper surface shape of the butt block 18 is rounded. The arc of the rounded corner of the butt block 18 is the same as the arc of the rounded corner of the butt plate 113. By setting the butt plate 113 and the butt block 18 to be rounded, when the worker finds that the installation position of the SMT is wrong, the SMT can be removed from the PCB board by pulling upward without affecting the PCB board and the SMT, thereby increasing the installation fault tolerance.

[0031] In this embodiment, the arrangement of the abutment plate 113, the abutment block 18, the elastic telescopic rod 19, the bracket 16 and the elastic slide bar 15 can increase the friction between the single-row upright SMT and the PCB board when the single-row upright SMT is installed on the PCB board, and can stably fix the SMT on the PCB board without soldering, which is convenient for workers to solder.

[0032] Working principle: when the single-row upright SMT is installed on the PCB board, after the positioning rod 10 and the rib 7 are aligned with the installation position of the PCB board, the single-row upright SMT is installed on the PCB board. When the originally inclined abutment plate 113 contacts the installation opening or the installation body on the PCB board, the abutment plate 113 is squeezed by the installation opening or the installation body, and the elastic slide bar 15 is retracted into the limiting groove 111 through the transmission of the bracket 16 and the connecting block 14. At the same time, the elastic slide bar 15 pushes the abutment plate 113 outward through its own elasticity. The elasticity of the elastic slide bar 15 increases the friction force with the installation opening or the installation body of the PCB board. At the same time, the gap between the slide groove 17 and the abutment block 18 further increases the friction force with the installation opening or the installation body, and the elastic telescopic rod 19 makes the abutment block 18 always contact with the surface of the installation opening or the installation body, thereby effectively ensuring that the single-row upright SMT is more stable after installation.
