Embodiment 1

[0070] For the processing technology of piercing HDMI electrical connector, see the attached figure 1 , which includes the following steps:

[0071] Stamping terminal processing, stamping and forming terminal 13, see attached Figures 19 to 23 , the front end of the terminal 13 is the electrical contact part 1, the middle part of the terminal 13 is the shaft 2, and the rear end of the terminal 13 is the electrical connection part 3, and the electrical connection part 3 is formed with three fangs 4 with staggered tips, and the fangs 4 are arranged on the terminal On the electrical connection part 3 of 13, the canines 4 punched out are in the shape of a pyramid, and the inner surface 5 of the canines 4 is formed with an arc surface, and the tips of the three canines 4 are respectively inclined to the outside. The direction of the inner surface 5 of the tooth 4 is the same, and is opposite to the direction of the inner surface 5 of the canine 4 located in the middle. The three c...

Embodiment 2

[0102] The processing technology of the puncture type HDMI electrical connector, this embodiment is to continue processing after completing the various processing steps of the first embodiment, and its various production steps are the same as the first embodiment, and this embodiment also includes the following steps:

[0103] In the plastic shell injection molding step, the outer iron shell 11 and the electrical connector assembly are placed in an injection mold, and a plastic shell is injected outside the outer iron shell 11 .

[0104] Since the puncture-type HDMI electrical connector of the present invention has made a huge breakthrough in thinning and miniaturization, the thickness of the electrical connector is far smaller than the minimum thickness defined by the micro HDMI electrical connector, so it can be electrically connected The outside of the connector is injection-molded with a housing, and the thickness of the electrical connector injected with the housing is sti...

Embodiment 3

[0107] piercing terminal, see attached Figures 19 to 26 The front end of the terminal 13 is an electrical contact part 1, the middle part of the terminal 13 is a shaft 2, and the rear end of the terminal 13 is an electrical connection part 3. At least two fangs 4 with staggered tips are formed on the electrical connection part 3. The fangs 4 are Pyramid shape, the inner surface 5 of the canine 4 is formed with an arc surface.

[0108] Three canines 4 are arranged on the electrical connection portion 3 of a terminal 13, wherein the direction of the inner surface 5 of the canine 4 at the front end and the rear end is the same, and the direction of the inner surface 5 of the canine 4 in the middle is opposite to that of the arc. The surface is formed on the upper end position of the inner side surface 5 of the canine 4 .

[0109] The three fangs 4 form a "V"-shaped or "U"-shaped core wire holder on the vertical projection plane, see attached Figure 23 . The front end of the ...

Abstract

The invention relates to an electric connector and the technical field of processing technique, in particular to a puncture type terminal, an electric connector and a manufacturing technique thereof; the processing technique comprises the processing of punching terminals, the processing of wire arrangement, the injection molding of an upper cover and a lower cover, puncture processing, removing strip material, assembling a front rubber core and an outer iron shell; wherein, the upper cover and the lower cover are respectively molding-injected at the middle and rear parts of the corresponding arrayed terminals; the processing technique solves the problem that the existing electric connector can not solve: the contact is unstable and poor, the electrical impedance is high and the electric connector can not be miniaturized; at least two tip teeth, the tip ends of which are distributed in a staggering way, are formed on the electrical connecting part of the puncture type terminal, and the tip tooth is a pyramid shape, and a cambered surface is formed on the inner side surface of the tip tooth; the tip tooth reduces the electrical impedance of the electric connector; the upper cover and the lower cover of the puncture type HDMI electric connector are respectively formed on the arrayed terminals, and the puncture type tip tooth is formed at the rear end of the terminal; the electric connector is more miniaturized and thinned, thus greatly improving the performance of the electric connector.

Description

Technical field: [0001] The invention relates to the technical field of electrical connectors and processing techniques thereof, and more specifically relates to piercing terminals, electrical connectors and production techniques thereof. Background technique: [0002] At present, there are types of electrical connectors such as HDMI, DVI, DisplayPort, VGA, Fi-X, etc. These electrical connectors play a pivotal role in electronic products. They are responsible for data transmission and signal transmission between electronic products, such as HDMI high Clear multimedia interface (full name High-DefinitionMultimedia Interface), HDMI high-definition multimedia interface can provide up to 10Gbps transmission rate, can transmit uncompressed and high-quality audio and video signals without conversion, suitable for digital home appliances such as high-definition digital TV, DVD Players, DVD recorders and other digital audio-visual products. [0003] At present, the connection metho...
