9,11,10 and

12,14,13 are staggered to form four groups of holding wire A respectively, so every group of holding wire A corresponding connector SMT welding foot 21 ' becomes stagger mode, finished product assembling back is difficult for detecting and can influencing high-frequency test, and can cause the assembling difficulty because of the problem of two row SMT welding foot coplane degrees, the rosin joint phenomenon usually takes place, the fraction defective height, processing cost is promoted, the front row also can be lived and can't detect and keep in repair by shelves in the Reflow Soldering processing procedure simultaneously, quality can not get ensureing, is unfavorable for manufacturing.

The utility model content

The utility model is at the existing disappearance of above-mentioned prior art, and main purpose is to provide a kind of Miniature HDMI connector, and it is easy to processing, helps improving working (machining) efficiency and quality.

For realizing above-mentioned purpose, the utility model is taked following technical scheme:

A kind of Miniature HDMI connector, comprise insulating base frame, first row's conducting terminal, second arranges conducting terminal and is coated on the outer shielding case of insulating base frame, described insulating base frame comprises main body and the tongue piece that extends forward along main body, described first row's conducting terminal and second row's conducting terminal are fixedly arranged on the main body respectively, and this first row conducting terminal, the contact site of the second row conducting terminal front side is corresponding respectively be arranged at tongue piece on, lower surface, this first row conducting terminal, the extension of second row's conducting terminal rear side is bent to form the welding foot position, described first row's conducting terminal, each welding foot position of second row's conducting terminal is staggered in together and forms side by side a row respectively.

Described first row's conducting terminal, second row's conducting terminal are formed with four groups of signal terminals each other, and each welding foot position system is arranged in together continuously in every group of signal terminal.

The main body afterbody of described insulating base frame is provided with a plurality of fixing caulking grooves of extension that are used for first row's conducting terminal.

Described shielding case front end both sides are respectively extended vertical position welding pin always downwards, and both sides, described shielding case rear end are bent with a SMT welding foot downwards.

The utility model advantage is to utilize first row's terminal, second row's terminal extension form of scattering to enlarge the PIN distance, make each welding foot bit interleave of two rows terminal form a row, help when so assembling adjusting, product also is easy to processing, and avoided traditional coplane degree and Reflow Soldering processing procedure to bring the problem that detects and keep in repair difficulty, improved working (machining) efficiency and quality effectively because of two row's welding foots.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

See also Fig. 3 to shown in Figure 5, a kind of Miniature HDMI connector, comprise insulating base frame 10, first row's conducting terminal 20, second arranges conducting terminal 30 and is coated on insulating base frame 10 shielding case 40 outward, described insulating base frame 10 comprises main body 13 and the tongue piece 12 that extends forward along main body 13, described first row's conducting terminal 20 and second row's conducting terminal 30 are fixedly arranged on respectively on the main body 13, and this first row conducting terminal 20, the contact site 21 of second row's conducting terminal, 30 front sides, 22 corresponding respectively be arranged at tongue piece 12 on, lower surface, this first row conducting terminal 20, the extension of second row's conducting terminal, 30 rear sides is bent to form welding foot position 221,321, described first row's conducting terminal 20, each welding foot position 221 of second row's conducting terminal 30,321 are staggered in together and form side by side a row respectively.
