Description
Technical Field
The invention relates to the field of electronic manufacturing equipment, in particular to a manufacturing method of a type-c female seat.
Background
In 12 months in 2013, a USB3.0 promotion team publishes a rendering map of a next-generation USB type-c connector, the type-c connector adopts a two-sided symmetrical design, the problem that a USB interface is always inserted inaccurately, which puzzles users for many years, is solved, and meanwhile, the type-c connector is thinner, has higher transmission speed, stronger power transmission and other characteristics, and has higher performance.
Since the release of the type-c connector, the characteristics of the type-c connector have made it the first choice interface for various new electronic terminal devices, the type-c female socket, as the interface mounted on the electronic device, generally includes a base body and a shell, the base body is embedded with an upper row of terminals and a lower row of terminals, and the front edge of the upper and lower surfaces of the base body is exposed, the terminals are composed of a plurality of (at most 12) pins (pins) side by side, and according to the arrangement mode of the pins on the terminals, the two different layout modes of the upper and lower pin row mirror symmetry layout and the upper and lower pin row staggered layout can be divided; the manufacturing precision requirement of the staggered layout form of the upper row of needles and the lower row of needles is low, the upper limit of the density of the needles is lower than that of the mirror symmetry layout form of the upper row of needles and the lower row of needles, and the main purposes of the two layout forms are distinguished: the staggered arrangement of the upper and lower rows of needles is mainly used for middle and low-grade electronic equipment, and the mirror-symmetrical arrangement of the upper and lower rows of needles is mainly used for high-grade electronic equipment.
Chinese publication No.: CN109301566A, discloses a usb type-c female seat module formed by one-time injection molding and a manufacturing method thereof, the abstract content: the usb type-c female socket module comprises an insulation body, an integrated terminal group and a clamping hook piece; the clamping hook piece is fixed together relative to the integrated terminal group through the material belt and is fixed on the insulating body through injection molding. Through adopting integral type terminal group, the relative integral type terminal group of cooperation trip piece is in the same place and injection moulding fixes on insulator simultaneously through the material area is fixed for this product can adopt one shot injection moulding preparation to accomplish, has replaced the mode of traditional many times shaping and assembly, makes insulator simple structure, effectively improves production preparation efficiency, has reduced the cost of product, and does benefit to and guarantees the product quality, makes things convenient for production.
The invention actually solves the problem of complicated production process of staggered arrangement of upper and lower rows of pins, and does not have good guidance function on the production process of complicated mirror-image symmetrical arrangement of the upper and lower rows of pins, because the pins are flat and can only swing longitudinally, the staggered arrangement of the upper and lower rows of pins is realized, and only one pin is arranged in a longitudinal column, so that the upper and lower rows of pins can not be contacted with each other actually even if the upper and lower rows of pins are injected simultaneously.
Because high-grade electronic equipment has high requirements on parts, most of the female seats adopt mirror symmetry layout of an upper pin row and a lower pin row, and the existing female seats adopting mirror symmetry layout of the upper pin row and the lower pin row generally adopt the following two production modes:
1. the upper and lower needles are respectively formed by punching, then the upper and lower needles are required to be respectively subjected to pre-injection molding and injection molding, and then the upper and lower needles are combined together for final injection molding.
2. The upper and lower needle of arranging is respectively through stamping forming, then go up the needle of arranging, the needle of arranging all need be respectively to carry out the preliminary moulding plastics and the shaping is moulded plastics, later with last needle of arranging and the mode combination of arranging the needle down through mechanical fastening together, this technology relates to four kinds of different injection moulding and two kinds of different stamping processes altogether, need use four sets of different injection moulding moulds and two sets of different stamping die, compare last technology, this method is simple relatively, and the cost is also lower, but the phenomenon of collapsing the needle, withdraw of the needle can appear in the product, influence the yields.
Therefore, a production method capable of effectively simplifying the mirror-symmetric layout of the upper and lower pin rows and the type-c female socket is urgently needed in the industry at present.
