Background
An electrical connector for circuit substrates, commonly referred to as a board-to-board electrical connector, is generally used to electrically connect two circuit substrates, and the board-to-board electrical connector generally includes a male electrical connector and a female electrical connector mated therewith. The related prior art can refer to the patent publication No. CN201060991Y of the invention in China.
In the board-to-board electrical connector disclosed in the prior art, the male end electrical connector includes a male end insulator made of plastic, a male terminal fixed on the male end insulator, and a male end fixing member, the male end insulator includes a bottom plate substantially in the shape of a rectangular parallelepiped plate, and a pair of long peripheral plates and a pair of short peripheral plates connected to each other and extending upward in the thickness direction of the bottom plate along the edge of the bottom plate, the male terminal is fixed on the long peripheral plates, and the male end fixing member is fixed on the short peripheral plates.
In addition, the female-end electrical connector comprises a female-end insulator made of plastic, a female terminal fixed on the female-end insulator and a female-end fixing piece, wherein the female-end insulator comprises a bottom wall in a shape of a rectangular plate, a pair of long peripheral walls and a pair of short peripheral walls which are formed by extending upwards along the edge of the bottom wall in the thickness direction of the bottom wall and are connected with each other, and an island part formed by extending upwards along the middle part of the bottom wall in the thickness direction of the bottom wall. The long peripheral wall, the short peripheral wall, the bottom wall and the island are encircled together to form an annular butt joint space. The female terminal is fixed on the long peripheral wall, at least part of the female terminal elastically protrudes into the butting space and is used for butting and contacting with the male terminal, and the female terminal fixing piece is fixed on the short peripheral wall.
The male end electric connector and the female end electric connector can be fixed to the corresponding circuit substrates through welding respectively. During butt joint, the male end electric connector is correspondingly inserted into the butt joint space of the female end electric connector, and signal transmission between the two circuit baseplates is realized through the electric contact of the male terminal and the female terminal. The male end fixing piece and the female end fixing piece realize buckle fixing through a buckle matching structure and are used for enhancing butt joint buckling force of the male end electric connector and the female end electric connector.
The electric connector in the prior art is generally used in the field of devices such as smart phones, notebook computers, digital cameras, unmanned aerial vehicles and the like, so that the electric connector is generally small in overall dimension, and particularly thin in thickness (for example, the thickness of the electric connector currently used for smart phones is even 0.4-0.5 mm). In some forms, a greater number of terminals are required, which results in a greater length than the thickness of the connector. Therefore, the overall flatness of the connector is difficult to control, and particularly, when the electrical connector is soldered to a corresponding circuit board, the electrical connector is partially or entirely heated by soldering to cause warpage deformation in the thickness direction of the circuit board, which affects the soldering stability between the terminals and the circuit board, and makes it easy to cause unstable connection between some of the terminals and the circuit board.
In some applications, it is necessary to shield the two rows of terminals located on the two long peripheral walls/long peripheral plates from each other to prevent crosstalk or interference between the two rows of terminals. Particularly in such a form with a small outer dimension, it is sometimes necessary to prevent signal crosstalk or interference.
In view of the above, there is a need to design a new electrical connector and its combination to overcome the above problems.

In the present invention, the abdicating space 2402 should be made as small as possible, and it is preferable that the female end butt-joint part 242 has no or only a small amount of elastic deformation space after the male end butt-joint part 142 and the female end butt-joint part 242 are matched and butted and fastened. In addition, the size of the docking space 2401 should be matched with the male end docking portion 142 as much as possible, and after the male end docking portion 142 is mated and docked with the female end docking portion 242, the male end docking portion 142 completely fills the docking space 2401 or fills the docking space 2401 as much as possible in the length direction of the female end electrical connector 2. With this design, the hole structure of the female metal piece 24 in the width direction of the female electrical connector 2 is reduced as much as possible, so as to achieve better shielding, isolating and grounding functions.
Referring to fig. 3 to 5, the present invention shows two forms of the female end joint part 242, and the structural differences are mainly: in one embodiment, the female end interface 242 is an upright cantilever-like structure, and in another embodiment, the female end interface 242 is an arc-shaped cantilever-like structure. The cantilever length of the female end interface 242 in both embodiments is different and can be selected according to the actual requirement. Of course, the actual shape of the female end interface 242 may be modified equivalently based on the embodiments of the present invention.
In another embodiment, the pair of female end docking portions 242 for docking with the male end docking portion 142 may be designed as only one, that is, a resilient female end docking portion 242 is correspondingly matched and snapped with the male end docking portion 142. At this time, one side of the one female terminal mating part 242 forms the mating space 2401, and the other side forms the relief space 2402.

In this embodiment, the female end mating portion 24 formed on the female end metal member 24 is in a vertical cantilever shape and has no elasticity in the length direction of the female end electrical connector 2, and at this time, female end insertion spaces (not shown) for the male end mating portion 14 to be inserted and elastically deformed are formed at both sides of the female end mating portion 24. And a male end abutting portion 142 formed on the male end metal piece 14 and having an upright cantilever shape and being elastically deformable in a length direction of the male end electrical connector 1, wherein a male end insertion space (not shown) into which the female end abutting portion 24 is inserted is formed at one side of the male end abutting portion 142. In such an embodiment, the number and location of the female 24 and male 14 end interfaces, and the size of the female and male insertion spaces follow the above design considerations.
In addition, in another embodiment, the male end interface portion 142 and the female end interface portion 242 can be designed to be elastic along the length direction. And the elastic male end butt-joint part 142 is matched and buckled with the elastic female end butt-joint part 242. For example, the embodiment may be a cantilever structure with the male end interface designed to resemble the shape of the female end interface.
Referring to fig. 5, after the male electrical connector 1 and the female electrical connector 2 are mated, in the mating direction, the male metal part 14 and the female metal part 24 are attached (only a gap caused by a process tolerance, an assembly tolerance, a mating tolerance, etc.) to ensure better shielding, isolating and grounding functions between the two rows of terminals. In addition, in the length direction of the male electrical connector 1 and/or the female electrical connector 2, the main body module composed of the male body 141 and the female body 241 extends over the entire length of one row of the male terminals 12 and/or one row of the female terminals 22, so as to ensure better shielding, isolating and grounding functions between the two rows of the terminals. In addition, in the mating direction, the main body module composed of the male end main body portion 141 and the female end main body portion 241 extends from the side of the male end bottom wall 111 close to the corresponding circuit board to the side of the female end bottom wall 214 close to the corresponding circuit board at the full height (only a gap caused by a process tolerance, an assembly tolerance, a mating tolerance, a floating section difference generated between the male end electrical connector 1 and the female end electrical connector 2 and the circuit board due to welding, and the like is left), so as to ensure better shielding, isolating and grounding functions between the two rows of terminals.
In addition, in another embodiment, the relative widths of the male end body portion 141 and the female end body portion 241 in the mating direction can be adjusted. For example, the width of the male end body 141 is increased to make the male end body 141 protrude into the male end plugging space 110, the width of the female end body 241 is decreased, a recess (not shown) for recessing the male end body 141 is dug at a position corresponding to the island 213, and the lengths of the male end mating part 142 and the female end mating part 242 are increased or decreased. It should be noted that the main body module composed of the male terminal main body 141 and the female terminal main body 241 has a sufficient extension width in the mating direction and a sufficient extension length in the length direction, so as to ensure a better shielding and isolating function between the two rows of terminals.
In addition, in another embodiment, the female electrical connector 2 may not have the island 213 structure, and in this embodiment, the female insulator 21 of the female electrical connector 2 only includes a pair of female sidewalls 211, a pair of female end walls 212, and a female bottom wall 214 under the pair of female sidewalls 211 and the pair of female end walls 212. The pair of female side walls 211, the pair of female end walls 212 and the female bottom wall 214 together form a rectangular female plug space 210 for receiving the male electrical connector 1. The female end metal piece 24 is fixedly disposed at the middle portion of the female end bottom wall 214 in the width direction of the female end electrical connector 2 and extends along the length direction of the female end electrical connector 1.
