Description
Technical Field
The present disclosure relates to electrical connectors, and particularly to a connector for a substrate and a combination thereof.
Background
The related art refers to chinese patent No. CN201410658030.1, which discloses an electrical connector for connecting to a substrate, the electrical connector having a housing and a plurality of terminals held in the housing. The housing has: a bottom wall facing the mounting object surface and extending in the longitudinal direction; a protruding wall portion protruding upward from the bottom wall, and a side wall rising upward from the bottom wall. The space between the protruding wall portion and the side wall is formed as a receiving recess portion for receiving the fitting portion of the mating connector. The terminal is held by the housing by being integrally molded with the housing. The terminal has: a held portion held by the housing; and an elastic arm portion which is located on the protruding wall portion side and is formed with a contact portion. The elastic arm portion is formed to extend upward from the base portion along the protruding wall portion via a curved transition portion, and is elastically displaceable in a width direction perpendicular to the longitudinal direction. The base portion connects the held portion to an elastic arm portion at a position close to the bottom wall in the up-down direction, the contact portion for contacting with a mating terminal of a mating connector is formed on an upper end side of the elastic arm portion,
the protruding wall portion of the housing includes: a plurality of strip wall portions formed to be arranged at intervals in the longitudinal direction and to extend in the up-down direction; and a displacement tolerance recess formed so as to be recessed between adjacent strip wall portions in the longitudinal direction from a position of a side surface of the strip wall portion extending in the vertical direction, the displacement tolerance recess being capable of tolerance for elastic displacement of the elastic arm portion of the terminal, the held portion having an inner leg portion and an outer leg portion, the outer leg portion being held by the housing by being integrally formed with the housing, the base portion being located outside the displacement tolerance recess in a state of being incapable of displacement. The bottom wall has a hole penetrating in the vertical direction at a terminal position in the longitudinal direction, and the displacement allowing recess communicates with the hole.
The mating connector to be mated with the electric connector has: a synthetic resin case formed into a substantially rectangular parallelepiped shape; and a plurality of metal terminals arranged and held in the housing in the longitudinal direction of the housing, wherein the plurality of terminals of the mating connector are each of a fixed structure and cannot be elastically deformed.
In the prior art, such connectors for substrates are also designed in a customary manner in the industry, that is, terminals at the ends (female ends) of the electrical connectors are designed to be elastic structures, and terminals of the mating connectors (male ends) are designed to be fixed structures that cannot be deformed. However, since the terminal structure of the electrical connector end (female end) is relatively complex, a lot of molding process considerations need to be made when the terminal is integrally molded with the housing, for example, since the free end of the elastic arm portion of the terminal of the electrical connector end (female end) is upwardly shaped like an upright cantilever, in order to prevent the free end of the elastic arm portion from being bumped and deformed when being mated with a mating connector, a protective structure is generally formed at a corresponding position above the protruding wall portion. Thus further increasing the difficulty of the molding process. Even so, when the male end and the female end are butted, the elastic arm part is still possibly damaged.
In addition, in order to ensure that the two rows of elastic arm portions have enough elastic deformation space, a sufficiently wide displacement tolerance recess is provided; meanwhile, in order to ensure that the two opposite elastic arm parts are not overlapped with each other, a partition wall part with enough thickness is arranged between the two opposite elastic arm parts, so that the width dimension of the whole electric connector end (female end) becomes difficult to control. And the miniaturization cannot be achieved.
Therefore, it is necessary to design a new connector for a substrate and a combination thereof to solve the above technical problems.

Referring to fig. 6 to 8, the male insulator 21 is formed with a relief hole 210 along the vertical direction at the position of each elastic section 2203. The relief holes 210 are partially formed on the inner surface of the side wall 212, and partially formed on the bottom wall 211 adjacent to the side wall 212. The fixing section 2201 is partially embedded in the side wall 212, and partially protrudes into the relief hole 210. The elastic section 2203 is suspended in the relief hole 210. The resilient segments 2203 are resiliently deformable in the width direction within the relief holes 210 without contacting the female insulator 21 when the male connector 2 is mated with the female connector (shown in connection with fig. 6, 7, 8, 10). In this design, the elastic section 2203 is formed with a contact portion 2204 by bending, and the contact portion 2204 protrudes out of the surface of the side wall 212 for effectively contacting with the female terminal 12. Of course, the contact portion 2204 may be a convex hull structure.
In another embodiment, the female connector 1 may be designed into a single-row female terminal 12, i.e. the island wall 114 is removed, and the shielding member 13 is removed, in this embodiment, two contact pieces 1201 of each female terminal 12 are respectively fixed in two corresponding side walls 112 and correspondingly exposed from the inner side surfaces of the side walls 112, and the bottom wall 111, two side walls 112 and two end walls 113 jointly enclose a mating recess 10 for the male connector 2 that is opened upwards. Of course, the male connector 2 mated with the female connector 1 in the present embodiment needs to be correspondingly adjusted, that is, the male connector 2 is also designed into a single row of male terminals 22 and a single side wall 212 structure. The design purpose can also be realized.
Referring to fig. 8 to 10, when the male connector 2 is mated with the female connector 1. The U-shaped terminal portions 220 of the male connector 2 are inserted into the U-shaped contact arms 120 of the female connector 1 correspondingly. This ensures that neither the male terminal 22 nor the female terminal 12 are deformed by insertion (i.e., irreversibly deformed). In addition, the female terminal 12 with a complex structure is designed into a fixed structure, and the male terminal 22 with a simple structure is designed into an elastic structure, which is more beneficial to injection molding. The elastic section 2203 of the male terminal 22 can meet the process and functional requirements by only designing one relief hole 210 corresponding to the position of the male insulator 21. The design is simple, the manufacturing procedure is simple, and the butt joint performance is stable.
