[0011] Furthermore, the front and rear ends of the wiring board protrude from the first contact spring and the sixth contact spring respectively.

[0012] Furthermore, stepped grooves are respectively provided at the front and rear ends of the wiring board.

[0013] A connector hermaphroditic connection structure includes a first electrical connector and a second electrical connector that are plugged into each other, the first electrical connector and the second electrical connector both use the above-mentioned electrical connector (the structure of the electrical connector is not repeated here), and the second electrical connector is symmetrical with the center of the first electrical connector or the second electrical connector is formed by rotating the first electrical connector 180 degrees around a horizontal axis.

[0030] like Figures 1 to 3 As shown, an electrical connector provided by an embodiment of the present invention includes a wiring board 100, on which a first spring group and a second spring group are provided, the first spring group is inclined to the left side of the wiring board 100, and the second spring group is inclined to the right side of the wiring board 100, the first spring group includes a first contact spring 110, a second contact spring 120 and a third contact spring 130 arranged in sequence front and back, the second spring group includes a fourth contact spring 140, a fifth contact spring 150 and a sixth contact spring 160 arranged in sequence front and back, the fourth contact spring 140 is located between the first contact spring 110 and the second contact spring 120, the fifth contact spring 150 is located between the second contact spring 120 and the third contact spring 130, and the sixth contact spring 160 is located behind the third contact spring 130.

[0031] In one embodiment, in the front-to-back direction of the wiring board 100, the width of the first contact spring 110 is the same as the width of the second contact spring 120, and the width of the third contact spring 130 is twice the width of the first contact spring 110. By making the width of the third contact spring 130 twice the width of the first contact spring 110, the contact area can be increased, thereby making the connection of the electrical connector more reliable.

[0032] In one embodiment, the width of the fourth contact spring 140 is equal to the width of the third contact spring 130, and the width of the fifth contact spring 150 is the same as the width of the sixth contact spring 160, and both are equal to the width of the first contact spring 110. By making the width of the fourth contact spring 140 equal to the width of the third contact spring 130, the widths of the two electrical connectors correspond when plugged together.

[0033] In one embodiment, the right side of the terminal block 100 is provided with a first contact platform 210, a second contact platform 220 and a third contact platform 230, the first contact platform 210 corresponds to the first contact spring piece 110 in upper and lower parts and has the same width, the second contact platform 220 corresponds to the second contact spring piece 120 in upper and lower parts and has the same width, and the third contact platform 230 corresponds to the third contact spring piece 130 in upper and lower parts and has the same width.

[0034] In one embodiment, the first contact platform 210, the second contact platform 220 and the third contact platform 230 all include an inclined surface and a vertical surface, and a transition section is provided between the inclined surface and the vertical surface. The inclined surface can fit more closely with the contact spring of another electrical connector, thereby ensuring the contact effect.

[0035] In one embodiment, an L-shaped pressing plate 600 is provided on the left side of the wiring board 100. In the front-to-back direction, the length of the L-shaped pressing plate 600 is equal to the sum of the lengths of the first spring group and the second spring group.

[0036] In one embodiment, the front and rear ends of the wiring board 100 protrude from the first contact spring 110 and the sixth contact spring 160 respectively, so that the front and rear ends of the wiring board 100 can protect all the contact springs and prevent the front and rear components from interfering with the contact springs and causing damage.

[0037] In one embodiment, the front and rear ends of the wiring board 100 are respectively provided with stepped grooves, and the stepped grooves facilitate the clamping of the wiring board 100 and the electrical connector housing.

[0038] like Figures 4 to 7 As shown, a connector hermaphroditic connection structure provided by an embodiment of the present invention comprises a first electrical connector (an electrical connector located at the bottom) and a second electrical connector (an electrical connector located at the top) which are plugged into each other. Both the first electrical connector and the second electrical connector are electrical connectors as in the above embodiment. Figure 4 and Figure 5 As shown, the second electrical connector and the first electrical connector are plugged into the same side. Figure 6 and Figure 7 As shown, the second electrical connector and the first electrical connector are plugged in opposite sides.

[0039] In one embodiment, when the second electrical connector is inserted on the same side as the first electrical connector, the first contact spring 110, the second contact spring 120, and the third contact spring 130 of the first electrical connector are all located in the L-shaped pressure plate 600 of the second electrical connector, and the L-shaped pressure plate 600 horizontally squeezes the ends of the first contact spring 110, the second contact spring 120, and the third contact spring 130 of the first connector.

[0040] In combination with the above embodiments, the use principle and working process of the hermaphroditic connector structure provided by the embodiment of the present invention are as follows:

[0041] When two electrical connectors need to be electrically connected, there is no need to distinguish between the front and back sides, and the second electrical connector can be inserted on the opposite side or the same side as the first electrical connector. When the second electrical connector is inserted on the opposite side to the first electrical connector, the first contact spring 110, the second contact spring 120 and the third contact spring 130 of the second electrical connector are respectively in contact with the first contact platform 210, the second contact platform 220 and the third contact platform 230 of the first electrical connector, and at the same time, the first contact spring 110, the second contact spring 120 and the third contact spring 130 of the first electrical connector are respectively in contact with the first contact platform 210, the second contact platform 220 and the third contact platform 230 of the second electrical connector, thereby realizing reverse side insertion. At this time, the first contact spring 110, the second contact spring 120 and the third contact spring 130 of the first electrical connector are tightly fitted under the tight pressing action of the first contact platform 210, the second contact platform 220 and the third contact platform 230 of the second electrical connector and will expand outward. In order to prevent the first contact spring 110, the second contact spring 120 and the third contact spring 130 of the first electrical connector from being plastically deformed, the second electrical connector is inserted on the same side as the first electrical connector, so that the first contact spring 110, the second contact spring 120 and the third contact spring 130 of the first electrical connector enter the L-shaped pressure plate 600 of the second electrical connector. At this time, the sixth contact spring 160, the fifth contact spring 150 and the fourth contact spring 140 of the second electrical connector are in contact with the first contact platform 210, the second contact platform 220 and the third contact platform 230 of the first electrical connector respectively, and the fourth contact spring 140, the fifth contact spring 150 of the first electrical connector are in contact with the first contact platform 210, the second contact platform 220 and the third contact platform 230 of the first electrical connector respectively. The sixth contact spring 160 contacts the third contact platform 230, the second contact platform 220 and the first contact platform 210 of the second electrical connector respectively, so that no matter the two electrical connectors are inserted on the same side or the opposite side, they can form six groups of contacts after insertion, and the left and right sides of the terminal block 100 are subjected to balanced forces to avoid the terminal block 100 being subjected to force on only one side, which can improve the connection stability of the electrical connector as a whole, and the L-shaped pressure plate 600 of the second electrical connector will reversely squeeze the ends of the first contact spring 110, the second contact spring 120 and the third contact spring 130 of the first electrical connector to return them to their original positions to avoid plastic deformation, thereby improving the service life of the electrical connector.

[0042] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
