Description

Technical Field

[0001] The utility model relates to the technical field of electric connectors, in particular to an electric connector with a positioning structure. Background Art

[0002] Electrical connectors can be quickly plugged in and used. They are currently widely used in electronic products, especially computers, communication equipment, etc., and are used in combination with motherboards. For wire-welding electrical connectors, it is very unstable to use only the pin end for welding, and the pin position cannot be properly positioned, which cannot be ignored for some precision circuit devices. In addition, the spacing between the solder pins extending from the terminals is small, and solder often sticks to each other, resulting in a short circuit between the terminals, making welding difficult and productivity low. In addition, in traditional wire-welding electrical connectors, the solder pins extending from the terminals are usually suspended and extended, lacking positioning, and are easily bent and deformed during the welding process, affecting production and resulting in a high rate of product defects.

[0003] Chinese patent CN206727360U discloses an electrical connector with precise positioning of welding feet. The electrical connector achieves precise positioning of the male and female heads by inserting the pin into the female core seat through the first pin hole and then inserting the positioning piece into the welding seat. However, in actual operation, since the first pin hole and the pin are both arranged inside the female head and the male head, it is relatively troublesome to align the male and female heads. At the same time, the male and female heads are relatively fixed by rotating the thread, but this method often requires manual tightening with the help of tools. Manual tightening alone can easily cause the male and female heads to loosen after long-term use, resulting in inconvenience in use. Utility Model Content

[0023] When the male connector 1 and the female connector 2 need to be plugged together, the operator can quickly position the male connector 1 and the female connector 2 through the first positioning mechanism 41. The second positioning mechanism 42 can facilitate the operator to quickly identify the front and back sides of the male connector 1 to prevent the male connector 1 and the female connector 2 from being plugged in incorrectly. After the male connector 1 and the female connector 2 are connected, the sealing device 5 can be used to effectively improve the sealing between the connection between the male connector 1 and the female connector 2, and effectively isolate the external water vapor and dust. The fixing module 3 can facilitate the operator to quickly connect the male connector 1 and the female connector 2 to prevent the male connector 1 and the female connector 2 from loosening due to external force after long-term use, thereby causing the connection between the male connector 1 and the female connector 2 to loosen.

[0024] See also Figure 3 and Figure 5 As shown, the fixing module 3 includes a first fixing device 31 and a second fixing device 32 , and the first fixing device 31 and the second fixing device 32 are arranged on the upper and lower sides of the female connector 2 .

[0025] By providing the first fixing device 31 and the second fixing device 32 , the upper and lower sides of the male connector 1 and the female connector 2 can be fixed, thereby preventing the male connector 1 and the female connector 2 from being disconnected due to external force.

[0027] When the male head 1 and the female head 2 need to be fixed, the flip plate 313 is pressed downward and flipped until the first barb 314 and the second barb 315 are engaged and engaged. When the flip plate 313 rotates, the fixing mechanism 312 is driven away from one side of the female head 2 to fix it, thereby achieving rapid fixation of the male head 1 and the female head 2. Compared with the rotational fixation of traditional threads, this fixing method is convenient and fast, and is not easy to loosen.

[0028] See also Figure 4As shown, the fixing mechanism 312 includes a fixing ring 3121 and a third barb 3122 ; the third barb 3122 is disposed on the male head 1 ; and the fixing ring 3121 is rotatably disposed on the flip plate 313 .

[0029] When the fixing mechanism 312 is needed to fix the male head 1 and the female head 2, the fixing ring 3121 is put on the third barb 3122 away from the flip plate 313, and the flip plate 313 is pressed until the second barb 315 is matched and fixed with the first barb 314. When the flip plate 313 is flipped downward, the flip plate 313 drives the fixing ring 3121 to move toward the third barb 3122 until the fixing ring 3121 is matched and locked with the third barb 3122, thereby realizing that the fixing mechanism 312 fixes the male head 1 and the female head 2.
