Description
【Technical field】
The present invention relates to a kind of method of manufacture HDMI connection plugs.
【Background technology】
HDMI connection plugs are widely used at present., it is necessary to using tin in the production process of HDMI connection plugs
Naked twisted wire is welded with conducting terminal.Following several techniques be present in traditional soldering：
1st, using tin cream filling mode, the use of tin cream due to being limited by environment temperature and ingress of air time, because
This filling when, it is necessary to tin cream is filled on the weld part of conducting terminal now fill out it is current, but this technique still have it is as follows
The shortcomings that：A, moment heating occurs that tin is fried and easily causes short circuit；B, used tin cream is now squeezed to be collided, once collided
The stability and welding effect of later stage welding are influenced whether, therefore is entirely being added using the HDMI connection plugs for now squeezing current tin cream
Difficulty is deposited during work, can not also use vibration feeder to carry out feeding；C, the cost of tin cream is higher by the several times of solder；
2nd, by the way of tin in hot dipping.The shortcomings that following be present in this technique：A, tin amount is few；B, flux-free；C, tin
The temperature of secondary thawing must be more than 300 degree, are otherwise difficult liquefied, but more than 300 degree of high temperature can be inserted to HDMI connections
Plastic connector, the plastic cement part such as plastic cement wire rod of head produce damage；D, tin surfaces easily aoxidize, and dry joint situation easily occur；
3rd, by the way of hot pressing solder.The shortcomings that following be present in this technique：A, contact heating is because of destabilizing factor
Numerous, the weld part after the only solder surface thawing that hot pressing solder leans on conducting terminal links together.Heating-up temperature mistake
Low, weld part is connected unstable or incomplete with solder surface attachment, in whole process, easily occurs the feelings such as tin
Condition；Heating-up temperature is too high, can destroy the component ratio of solder itself so that the temperature of the secondary thawing of solder improves, and causes solder
The destabilizing factor of following process program increases.B, due to above mentioned problem, so hot pressing solder can only pass through simple concora crush side
Formula is pressed into column, and that outside wall surface that solder contacts with naked twisted wire is pressed into plane, and naked twisted wire is only and solder outer wall one during welding
Face contacts, and in welding, such welding easily the phenomenon of dry joint or open circuit or short circuit occurs, causes defective products repair rate high.
Therefore, the present invention is based on the insufficient and caused of the above.
【The content of the invention】
The present invention seeks to overcome the deficiencies in the prior art, there is provided a kind of method of manufacture HDMI connection plugs, the party
Method realizes that naked twisted wire is automatically imported in U-shaped solder, more stably ensures the complete liquid of solder and formed by being cold-pressed solder
360 ° of welding comprehensively, so as to which conducting terminal and naked twisted wire closely be welded together, avoid the occurrence of dry joint or open circuit or short circuit,
It under Long-term Vibration is also not in fall tin in the way of transport or in vibration feeder, it is ensured that Product jointing quality.
The present invention is achieved by the following technical solutions：
A kind of method of manufacture HDMI connection plugs, it is characterised in that：Comprise the following steps：

【Embodiment】
The invention will be further described below in conjunction with the accompanying drawings：
A kind of method of manufacture HDMI connection plugs, comprises the following steps：
A：By multiple conducting terminals 2 and the assembly connection of connector assembly 1, described conducting terminal 2 is provided with weld part 3, described
Weld part 3 include pad 31 and be respectively provided at the both sides of pad 31 and with pad 31 it is integrally formed weld the wing 32, the described weldering wing
32 surround U-shaped welding groove 33 with pad 31；
B：Under normal temperature state in the described welding groove 33 press-in solder 4, solder 4 during welding groove 33 be pressed into and
The cell wall 33a of welding groove 33 is closely connected, and the U-shaped holding tank 41 that can accommodate naked twisted wire 5 is formed on solder 4；
C：Naked twisted wire 5 is placed in holding tank 41, and ensures that the outer peripheral face of naked twisted wire 5 is less than the notch of holding tank 41.
D：Solder 4 is melted on automatic welding machine, so that the notch of the scolding tin closing holding tank 41 melted.
By above-mentioned steps A to step C, naked twisted wire 5 is presented by 4 three sides surrounded state of solder, outer due to naked twisted wire 5
Side face is less than the notch of holding tank 41, and therefore, when being welded on automatic welding device in step D, solder 4 melts and very
Easily close the notch of holding tank 41 and fill up holding tank 41 so that U-shaped solder 4 realizes 360 °, and welding, naked twisted wire 5 are complete comprehensively
Surround, so that naked twisted wire 5 tightly welds together with conducting terminal 2, be not in dry joint or open circuit, in transportation
In be also not in fall tin situation, substantially increase the quality of product.Moreover, solder 4 be pressed into welding groove 33 in and with weld part 3
The process of connection is the cold press operation under normal temperature state, will not destroy the structure proportion of solder 4 and scaling powder, it is ensured that follow-up
Firm welding when being welded on automatic welding device.
Described solder 4 is provided with the protuberance 42 for protruding from the weldering lateral wall of the wing 32, in welding, described protuberance 42
Melt and formed can fill up holding tank 41 the protuberance 42 of closure 44. protrude from weldering the wing 32 lateral wall, it can be ensured that
Melt during welding with enough scolding tin and fill up holding tank 41, so that U-shaped solder 4 realizes 360 ° of welding comprehensively, ensure
Naked twisted wire 5 is surrounded entirely.
The inwall of the described weldering wing 32 is provided with neck 34, and described solder 4 is provided with the raised line that can be engaged with neck 34
43.The raised line 43 engaged with neck 34 is formed when solder 4 is pressed into welding groove 33, on solder 4.Pass through neck 34 and raised line
43 cooperation so that solder 4 is connected to obtain more secure rigid with conducting terminal 2, is not in fall tin situation.
Fore-and-aft direction extension of the described neck 34 along welding groove 33, therefore, neck 34 is in the raised line 43 on solder 4
Now similar to the attachment structure of back-off, prevent the abjection out of U-shaped welding groove 33 of solder 4 from dropping, it is ensured that naked twisted wire 5 and conducting terminal 2
The fastness of connection.
The described weldering wing 32 is provided with up-narrow and down-wide open slot 35, described solder 4 shape when being pressed into welding groove 33
Into the embedded division 44 having in embedded open slot 35.During solder 4 is pressed into welding groove 33, solder just has partial portion insertion
Embedded division 44 is formed in open slot 35, because open slot 35 is up-narrow and down-wide shape, so the insertion opening of embedded division 44
It is difficult to take off again after groove 35, it is ensured that solder 4 is firmly connected with weld part 3, and then ensures that naked twisted wire 5 connects with conducting terminal 2
The fastness connect.
Multiple described conducting terminals 2 are in two rows and are equidistantly connected on connector assembly 1.
The above embodiment of the present invention is only intended to clearly illustrate example of the present invention, and is not to the present invention
All embodiments restriction.For those of ordinary skill in the field, it is all the spirit and principles in the present invention it
