As an example, the female contact module body 211 is a PCB, that is, the metal elastic pieces 212 with the same serial numbers on both sides are electrically connected through a circuit on the PCB, and one end of the PCB, which is away from the metal elastic pieces 212, is provided with a plurality of welding holes to realize welding between the PCB and an external circuit. Since the principle and the manufacturing method of the PCB panel are well known to those skilled in the art, it is not expanded in detail.

As shown in fig. 7 to 9, as an example, the metal dome 212 includes a first section 212a, a second section 212b and a third section 212c connected in sequence, one side of the first section 212a, which is not connected to the second section 212b, is connected to the female contact module body 211 (e.g., soldered to a PCB), and a middle portion of the first section 212a has a concave portion (not shown) recessed inward, so that flexibility of the metal dome can be improved. And in a further example, the width of the side of the second segment 212b connected with the third segment 212c is smaller than the width of the side connected with the first segment 212 a; the third segment 212c includes a bending portion 2121 bent inward (i.e., the direction in which the two sets of metal elastic pieces 212 approach each other), and a tail portion 2122 connected to the bending portion 2121 and tilted outward (i.e., the direction in which the two sets of metal elastic pieces 212 move away from each other) (and the tail portion 2122 can be bent slightly inward again), where the bending portion 2121 is a contact point with the conductive strip 112, i.e., when the conductive strip 112 is inserted between the two sets of metal elastic pieces 212, the bending point of the bending portion 2121 is attached to the surface of the conductive strip 112 (see fig. 6 again). Through the design, the electric connection between the conductive bar 112 and the metal elastic sheet 212 can be ensured, and meanwhile, the tail end of the metal elastic sheet 212 can be prevented from scratching and abrading the conductive bar 112 in the process that the male-end plug 1 is inserted into the female-end socket 2. It should be noted that the "first section", "second section" and "third section" are merely distinguished for convenience of description, and the three sections are not strictly divided in entity but are integrally connected and preferably integrally formed.

As an example, a single set of metal strips 212 includes 5 metal strips 212 and 5 conductive strips 112, the metal strips 212 in the same set are uniformly spaced, and the conductive strips 112 are uniformly spaced corresponding to the metal strips 212, that is, the distance between the conductive strips 112 is the same as the distance between the metal strips 212. The distance may be designed according to the overall size of the connector, and since the widths of the metal elastic pieces 212 are different, it can be understood that the distance between the center lines of two adjacent metal elastic pieces 212 is the same as the distance between two adjacent conductive strips 112, for example, within 2 mm. The conductive strips 112 include, but are not limited to, copper strips, which may be disposed on the male contact module body 111 by plating or directly in the form of conductive wires. The metal spring 212 is made of a metal material with good elasticity, including but not limited to copper or copper alloy.

Preferably, the steps 131 and the latches 242 are both multiple, and the multiple steps 131 and the latches 242 are distributed at intervals inside the corresponding housing. Of course, in other examples, in a case that the outer injection-molded housing 24 does not extend to the periphery of the inner housing 23, or in a case that the outer injection-molded housing 24 and the inner housing 23 are flush with each other, the buckle 242 may be correspondingly disposed on the inner circumference of the inner housing 23, which is not limited in this embodiment.

As an example, as shown in fig. 11, the connector further includes a silicone ring 3, and the silicone ring 3 is sleeved on the circumferential direction of the outer injection-molded part housing 24 and is adjacent to the opening of the outer injection-molded part housing 24. The opening of silica gel circle 3 is interfered with female end socket 2, and when inserting public end plug 1 in female end socket 2, silica gel circle 3 can be stopped the water that stain hinders on public end plug 1 and get off to avoid having water stain entering female end socket, play waterproof role.

As an example, as shown in fig. 12, a buffer structure 241 is further disposed on the outer side of the outer injection-molded housing 24 along the circumferential direction, which can play a certain role in protecting the connector, for example, when the connector falls, the buffer structure 241 first contacts the ground to play a certain role in buffer protection.

As an example, the male housing 13 is a soft plastic housing, while the inner housing 23 of the female socket 2 is an injection molded housing, while the inner housing 23 is also preferably an injection molded part.

The manufacturing process of the male plug 1 may be welding the male contact module 11 and the male wire 12, and then performing an injection molding process on the welded structure to prepare the male housing 13 on the surface, or sleeving the pre-prepared male housing 13 on the welded structure surface, which is not strictly limited in this embodiment.

The manufacturing process of the female terminal socket 2 may be that the female terminal contact module 21 and the female terminal wire 22 are welded, and then the inner housing 23 and the outer injection molding housing 24 are formed through an injection molding process in sequence, or the inner housing 23 and the outer injection molding housing 24 which are prepared in advance are sequentially sleeved on a structural surface obtained after welding, and in this embodiment, strict limitation is not imposed.
