[0002] The board-to-board connector is the connector product with the strongest transmission capacity among all connector product types. The traditional board-to-board connector is a pair, namely a male connector and a female connector that matches the male connector. The male connector and the female connector are respectively installed on the circuit board and combined by a tight fit method. However, the connection method between the male end and the female end of the existing board-to-board connector on the market adopts elastic contact between the male end housing and the armor on the central island of the female end, and the current-carrying capacity of this contact method is limited.

[0003] Therefore, it is necessary to design a board-to-board connector with more stable contact. Summary of the Utility Model

Detailed implementation manners

[0022] In order to make the above - mentioned objects, features and advantages of the present utility model more obvious and understandable, the following detailed description of the specific implementation manners of the present utility model will be given with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific implementations disclosed below.

[0023] The embodiment of the present application provides a board - to - board male seat connector and a connector assembly, which solve the technical problem in the prior art that there is only one pair of elastic contact points between the male end and the female end of the board - to - board connector, resulting in limited current - carrying capacity.

[0024] As Figures 1 to 3 shown, this is the first embodiment of the present application: A board - to - board male seat connector 1, which includes a longitudinally extended male - end insulating seat body 10 and two rows of male seat terminals 120 fixed on the male - end insulating seat body 10. The male - end insulating seat body 10 includes a pair of longitudinally extended male seat side walls 101, a pair of transversely extended male seat end walls 102 and a male seat slot 103 between the pair of male seat side walls 101 and the pair of male seat end walls 102. The two rows of male seat terminals 120 are arranged on the male seat side walls 101. Further in detail, each male seat terminal 120 includes a contact part 1201 exposed in the male seat slot 103 and a welding part 1202 extending out of the insulating seat body. A pair of male seat armors 110 are provided on the male seat end walls 102. Specifically, as Figure 2:The male seat armor 110 includes a fastening portion 111 and a first contact portion 112. The fastening portion 111 semi-surrounds the male seat end wall 102. The first contact portion 112 extends downward from the end of the fastening portion 111 and is bent. The first contact portion 112 includes a pair of first elastic contacts 1106 protruding into the male seat slot 103. Adding a pair of elastic contacts to the male seat connector can increase the current-carrying area, improve the contact reliability during power-on, enhance the current-carrying capacity, and reduce the temperature rise.

[0025] Specifically refer to Figure 1 and Figure 2 Near the positions of the two male seat end walls 102, there is a pair of card slots 1021. The fastening portion 111 includes a side plate 1101 and a top plate 1102 surrounding the male seat end wall 102. A bottom plate 1103 extends downward from the top plate 1102 and is bent outward. The bottom plate 1103 includes an opening portion 1104 in the middle and overlapping portions 1105 on both sides of the opening portion 1104. The first elastic contact 1106 is formed by bending upward from the inner port of the opening portion 1104 and is placed in the card slot 1021. The overlapping portions 1105 are adaptively clamped on both sides of the bottom of the card slot 1021.

[0026] Further refer to Figure 1 The length of the overlapping portion 1105 is greater than the length of the fastening portion 111. Appropriately extending the length of the overlapping portion 1105 can more stably fix the male seat armor 110 on the male end insulating seat body 10 and enhance the stability of the board-to-board connector.

[0027] As Figure 3 shown, on the outer side of the male seat end wall 102, there is a protruding engaging protrusion 1020, and on the inner wall of the side plate 1101, there is an inwardly recessed groove 11010. The engaging protrusion 1020 is engaged in the groove 11010. This setting is to stably install the male seat armor 110 on the male seat end wall 102 and further enhance the stability.

[0028] As a preferred way, the fastening portion 111 and the first contact portion 112 are of an integral structure. Using an integral design can increase the current-carrying area.

[0029] As Figures 4 - 7The second embodiment of the present application is shown. In this embodiment, a connector assembly is provided, which includes the board-to-board male connector 1 described in the first embodiment and a female connector 2 matingly connected thereto. The female connector 2 includes a longitudinally elongated female terminal insulating housing 20, two rows of female seat terminals 220 fixed on the female terminal insulating housing 20, and a pair of female seat armors 230 installed at the longitudinal two ends of the female terminal insulating housing 20. A central island portion 201 extending longitudinally is provided inside the female terminal insulating housing 20. A pair of middle island armors 210 are provided at both ends of the central island portion 201. The side wall of the connecting portion 211 of the middle island armor 210 is in contact with the first elastic contact 1106 in the male seat slot 103.

[0030] Further referring to Figure 6 , the middle island armor 210 includes a connecting portion 211 and a second contact portion 212. The connecting portion 211 wraps around both ends of the central island portion 201. The second contact portion 212 extends outward from one end of the connecting portion 211 and is bent upward. It includes a pair of second elastic contacts 2120 protruding inward. The second elastic contacts 2120 are in contact with the side plate 1101 of the male seat armor 110.

[0031] As Figure 7 shown, through the contact between the first elastic contact 1106 in the male seat slot 103 and the side wall of the connecting portion 211 of the middle island armor 210, and the contact between the second elastic contacts 2120 and the side plate 1101 of the fastening portion 111 on the male seat armor 110, a double elastic contact design between the male and female seats of the board-to-board connector is realized, which increases the contact reliability during power-on, improves the current-carrying capacity, and reduces the temperature rise.

[0032] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, 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, it should be considered as the scope described in this specification.

[0033] The above-described embodiments only express the implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
