Description

Technical Field

[0001] This invention relates to the technical field of electrical connectors, and particularly to an improved structure of a vertical electrical connector. Background Technology

[0002] Electrical connectors are used to connect different electronic components or modules, enabling the transmission of electronic signals between them. An electrical connector mates with a counterpart connector, and signals are transmitted through contact between the terminals of the connector and the counterpart connector. Therefore, an electrical connection is formed only after mating is completed, and the mating of the electrical connector marks the initiation of signal transmission between electronic devices.

[0003] Existing electrical connectors typically connect to the device on one side and to a circuit board on the other. Because the soldering ends of existing terminals are often arranged at equal intervals due to the terminal design, this creates several problems when soldering the corresponding holes on the circuit board. In view of this, the inventors of this invention have painstakingly researched and finally completed the improved electrical connector structure of this invention to overcome the shortcomings of the prior art. Summary of the Invention

[0004] The main objective of this invention is to provide an improved structure for an electrical connector, wherein the solder ends of the terminals have a spacing setting, which provides advantages for internal wiring applications.

[0005] To achieve the above objectives, the present invention provides an improved electrical connector structure, characterized in that it comprises:

[0006] An insulating structure includes a base and a tongue plate, the tongue plate being disposed at the front end of the insulating structure;

[0007] A first terminal includes a mating portion, a fixing portion, and a welding portion. The fixing portion is coupled to the base of the insulating structure, the mating portion is disposed on the tongue plate, and the welding portion protrudes from the base and is available for welding.

The functional terminals of the soldered portion of the first terminal and the power terminals have a first distance, and the functional terminals of the soldered portion of the second terminal and the power terminals have a second distance. The first distance and the second distance are greater than the distances between other terminals.

[0019] The improved electrical connector structure, wherein: the first spacing is greater than the second spacing, and the second spacing is greater than the spacing between other terminals.

[0020] The improved electrical connector structure, wherein: the second spacing is greater than the first spacing, and the first spacing is greater than the spacing between other terminals.

[0021] The improved electrical connector structure further includes a circuit board having a plurality of solder holes arranged in a manner corresponding to the arrangement of the solder portions of the first terminal and the second terminal.

[0032] Figure 3 This is a schematic diagram of the terminal structure of the present invention. Figure 4 This is a schematic diagram of the terminal structure from another perspective of the present invention. Please also refer to [the document / reference]. Figure 3 and Figure 4 As shown in the figure, the first terminal 20 is attached to one side of the spacer 40, and the second terminal 30 is attached to the other side of the spacer 40. Each terminal row of the first terminal 20 includes a conventional signal terminal pair 20a, two functional terminals 20b respectively disposed on both sides of the conventional signal terminal pair 20a, two power terminals 20c respectively disposed outside the functional terminals 20b, two pairs of high-frequency signal terminal pairs 20d respectively disposed outside the power terminals 20c, and two ground terminals 20e respectively disposed outside the high-frequency signal terminals 20d. The functional terminals 20b and power terminals 20c of the solder portion 26 of the first terminal 20 have a first distance D1. Please refer to [link to relevant documentation]. Figure 4 As shown, by Figure 4In view, each terminal row in the second terminal 30 also includes a conventional signal terminal pair 30a, two functional terminals 30b respectively disposed on both sides of the conventional signal terminal pair 30a, two power terminals 30c respectively disposed outside the functional terminals 30b, two pairs of high-frequency signal terminal pairs 30d respectively disposed outside the power terminals 30c, and two ground terminals 30e respectively disposed outside the high-frequency signal terminals 30d.

[0033] Please also refer to Figure 3 and Figure 4 As shown, the first terminal 20 has a third distance D3 between the functional terminal 20b and the power terminal 20c of the fixing portion 24, similar to the first terminal 20. The second terminal 30 has a fourth distance D4 (not shown) between the functional terminal 30b and the power terminal 30c of the fixing portion 34. The first distance D1, second distance D2, third distance D3, and fourth distance D4 are mainly used to allow space for wiring on the corresponding circuit board 70. In one embodiment, the first distance D1 is greater than the second distance, and the second distance D2 is greater than the distance between other terminals. Alternatively, the second distance D2 is greater than the first distance D1, and the first distance D1 is greater than the distance between other terminals; this is not the case.

[0034] Figure 5 This is a schematic diagram of the terminal structure from another perspective of the present invention. This is a schematic diagram of the terminal arrangement from a rear view. Please refer to the following documents as well. Figures 1 to 4 As shown in the figure, the first terminal 20 has a first spacing D1, and the second terminal 30 has a second spacing D2. The first spacing D1 and the second spacing D2 are staggered relative to each other. Therefore, when the soldering parts 26 and 36 are soldered to the corresponding circuit boards, the clearance area can prevent crosstalk and other factors from occurring during wiring.

[0035] Please also refer to Figure 1 and Figure 2As shown, the first terminal 20 is attached to one side of the spacer 30, and the second terminal 20 is attached to the other side of the spacer 30, clamping the spacer 40 from above and below. The spacer 40 may be made of insulating material, but is not limited thereto.

The first insulating member 12 and the spacer 40 respectively cover the first terminal 20; the second insulating member 14 and the spacer 40 respectively cover the second terminal 30. The base 102 of the insulating structure 10 extends along the tongue plate 104 and has two protrusions 106. These protrusions 106 protrude from the metal housing 50 during installation. The two protrusions 106 of the insulating structure 10 correspond to the two protruding ribs 62 of the outer housing 60 during installation. The two protruding ribs 62 correspond to the protrusions 106 and abut against the protrusions 106 during installation.

[0036] Figure 6 This is a schematic diagram of the circuit board routing structure of the present invention. Please also refer to [other documents / references]. Figures 1 to 5 As shown, in one embodiment, it further includes a circuit board 70 having a plurality of solder holes 72, the solder holes 72 being arranged to correspond to the arrangement of solder portions 26, 36 of the first terminal 20 and the second terminal 30. Figure 6 As shown, the upper row of weld holes is numbered A1 to A12 from left to right, and the lower row of weld holes is numbered B1 to B12 from right to left. The upper row of weld holes A1 to A8 form one group, and A9 to A12 form another group. A8 and A9 are separated by a gap to allow the wiring of the lower row of weld holes to pass through. It should be noted that this invention is not limited to A1 to A8 forming one group and A9 to A12 forming another; it can also be A1 to A4 forming one group and A5 to A12 forming another group, with A4 and A9 forming the third group. The A5 holes are spaced apart to allow the lower row of weld holes to pass through. Similarly, for the purpose of routing, the lower row of weld holes is arranged in a way that avoids the space between B1 to B8 and B9 to B12, with a space between B8 and B9. Alternatively, B1 to B4 can be arranged in a group and B5 to B12 in a group, with a space between B4 and B5. As long as the space can be avoided to allow for smooth routing of the upper and lower rows of weld holes, this invention does not limit the arrangement of the upper and lower rows of weld holes.

[0037] The improved electrical connector structure of the present invention has a first distance between the functional terminal of the solder portion of the first terminal and the power terminal, and a second distance between the functional terminal of the solder portion of the second terminal and the power terminal. The first distance and the second distance are set to be greater than the distance between other terminals. This staggered arrangement allows the wiring on the circuit board side corresponding to these terminals to have a clearance effect, further avoiding crosstalk and other factors during wiring.
