Description

If, the chinese utility model patent that the publication number is CN203553506U discloses a backplane connector (being equivalent to high-speed connector) that prevents signal crosstalk, this connector includes plastic part, metal support and a plurality of connection pieces of setting in the plastic part, and backplane connector still includes the shielding piece, has terminal and insulating piece, and in the insulating piece was inserted to the one end of terminal, the other end was connected with the plastic part, and the shielding piece setting is in the bottom of insulating piece. The connector ensures reliable contact in one direction by realizing connection through single-side contact when in use.

The connector further improves contact reliability with the mating contact in one direction by double-sided contact.
For another example, the chinese patent publication No. CN105977665B discloses a high-speed backplane receptacle connector having dual-contact differential signal terminals, the connector includes a plurality of pairs of differential signal terminals and a plurality of ground terminals, each differential signal terminal includes a first elastic contact arm and a second elastic contact arm, the first elastic contact arm forms a closed opening, the second elastic contact arm is located in the opening, the length of the first elastic contact arm is greater than that of the second elastic contact arm, and dual-contact connection is achieved through inner side surfaces of the first and second elastic contact arms and the mating contact member when the connector is in use. The connector improves signal transmission stability and contact reliability in one direction through a single-side multi-contact form.
For another example, a sheet-type contact, an electrical connector, and a printed board assembly disclosed in chinese patent application with application publication No. CN107104305A are disclosed, in which the sheet-type contact in the electrical connector includes a beam of a frame-shaped structure extending in the left-right direction, a press-fitting structure is provided on the lower side of the beam, the sheet-type contact is inserted into a slot of an insulator, conductive sheets are provided on the upper side of the beam and are oppositely disposed in the front-back direction and extend upward, the front portions of the conductive sheets oppositely disposed in the front-back direction are matched to form a contact portion of the contact, and an opening between the conductive sheets oppositely disposed in the front-back direction is matched. The connector further improves the signal transmission stability and the contact reliability in one direction by the form of double-sided multi-contacts.
In summary, the high-speed connector can elastically abut against the mating plug terminal in only one direction (e.g., left and right directions) by adopting the above-mentioned various contact forms. When the high-speed connector is in severe use environments such as high vibration, strong impact and the like, the contact element and the adaptive contact element in the high-speed connector are prone to shaking, the various contact elements cannot ensure that the other directions (such as the front and back directions) are elastically abutted against the adaptive contact element, the high-speed connector is easy to disengage from the adaptive contact element in the use process, and the contact reliability is low.

The jack contact piece can be abutted with the adaptive pin contact piece in multiple directions, and the contact reliability of the jack contact piece and the pin contact piece is enhanced. When the jack contact element is produced, the progressive die is firstly used for punch forming, then the bending forming is carried out, the distance between the contact cantilevers after the final forming is closer, and the distance is smaller than the unfolding size of the contact cantilevers. Therefore, two or more material belts are often required to be superposed and combined in the production of the jack contact element, so that the interference between parts before bending and forming is avoided; because the size is little, there is great degree of difficulty in the shaping of bending, and the part resilience after bending can't be avoided, size and part deflection volume after guaranteeing the shaping improve product contact reliability, must improve the mould precision to the manufacturing cost of mould has been increased, and then has increased the manufacturing cost of jack contact.

Detailed Description
The following further describes embodiments of the present invention with reference to the drawings.
The first embodiment of the high-speed connector of the present invention, as shown in fig. 2, includes a connector housing and a receptacle contact 21.
The connector housing comprises a shell and an insulator 22 clamped with the shell, a plurality of through holes penetrating through the shell are formed in the shell, mounting holes corresponding to the through holes one by one are formed in the insulator 22, and a jack contact piece 21 is correspondingly mounted in each mounting hole. As shown in fig. 3, the insulator 22 has barbs 24 thereon, and the housing has a locking groove 23 for engaging the barbs to fix the insulator 22 with the socket contact 21 mounted thereon to the housing.
As shown in fig. 5, the socket contact 21 includes a base 214, the base 214 is a plate-like structure, the plate-like base 214 is fixed on the insulator 22, and a side of the plate-like base 214 facing away from the housing has soldering pins 213 extending outward for soldering with a printed circuit board. The soldering leads 213 in this embodiment are in a plate-like structure and are integrated with the base 214 for easy stamping. Of course, in other embodiments, the soldering pin 213 and the base 214 may be in a separate structure, and the separate soldering pin 213 and the base 214 are fixed by soldering. The side of the base 214 facing away from the solder pins 213 has a socket contact section comprising a first pair of arms 211 and a second pair of arms 212 intersecting each other. The first and second pairs of cantilevers 211 and 212 each comprise two contact cantilevers 215, the four contact cantilevers 215 being arranged uniformly in the circumferential direction for enclosing a receptacle for plugging with an adapter pin, the inner sides of the contact cantilevers 215 having electrically conductive contact portions for electrically conductive contact with the adapter pin. The roots of the two contact cantilevers 215 of the first pair 211 and the two contact cantilevers 215 of the second pair 212 are integrally connected to form a fork structure.
As shown in fig. 6, the first cantilever pair 211 is a sheet-like structure with two coplanar contact cantilevers 215, and the root of the first cantilever pair 211 is integrally connected and coplanar with the base 214, so that the integrated first cantilever pair 211 and the base 214 are integrally formed through a stamping process; the first cantilever pair 211 has a slot 217 extending in the mating direction at a position where the two contact cantilevers 215 are integrally connected. As shown in fig. 7, the second pair of cantilevers 212 is a sheet-like structure with two contact cantilevers 215 coplanar so as to be integrally formed by a stamping process. The position where the two contact cantilevers 215 of the second pair of cantilevers 212 are connected is inserted into the slot 217 of the first pair of cantilevers 211, and the position where the two contact cantilevers 215 of the second pair of cantilevers 212 are integrally connected is inserted into the slot 217 of the first pair of cantilevers 211. The thickness of the insertion position of the second cantilever pair 212 and the insertion groove 217 is slightly larger than the width of the insertion groove 217, so that the tight fit of the first cantilever pair 211 and the second cantilever pair 212 is realized, the connection strength of the first cantilever pair 211 and the second cantilever pair 212 is enhanced, and the conductive contact of the first cantilever pair and the second cantilever pair is facilitated.

The protrusion 216 in this embodiment has one, but in other embodiments, the number of the protrusions may be multiple, or the protrusions are specifically protrusion segments extending along the plugging direction.
In this embodiment, the four contact cantilevers 215 are inwardly folded in the extending direction thereof, so that the end of the insertion hole surrounded by the four contact cantilevers 215 is a tapered structure, thereby enhancing the contact reliability with the mating pin. The conductive contact portions of the four contact cantilevers 215 that make conductive contact with the mating pin are lateral sides of the contact cantilevers 215 in the width direction. The contact cantilever 215 is subjected to a radial force applied by the pin when contacting the mating pin, and since the width of the contact cantilever 215 is much greater than its thickness, the lateral sides of the contact cantilever 215 in the width direction form conductive contact sites that enhance the compressive strength of the contact cantilever 215. The end of the four contact arms 215 facing away from the base 214 has radially outwardly inclined guide sections, each of which is enclosed in a flared configuration for guiding the mating pin into the receptacle.
In this embodiment, the insulator 22 is integrally formed by injection molding, and the socket contact 21 is placed in a mold before injection molding so that the insulator 22 and the socket contact 21 are fixed by injection molding, where the mold only performs a positioning function.

The socket contact 11 and the insulating base 12 in this embodiment are formed integrally by injection molding to form a pin member.
When the high-speed connector is used, the jack surrounded by each contact cantilever in the jack contact element of the high-speed connector 2 is inserted into the contact pin 111, the contact pin 111 is contacted with the side surface of each contact cantilever in the width direction, and each contact cantilever is elastically abutted to the contact pin 111 in multiple directions, so that the contact reliability of the high-speed connector and the contact pin is enhanced.
The second embodiment of the high-speed connector of the present invention is different from the first embodiment of the high-speed connector in that two contact cantilevers in the first and second cantilever pairs in the embodiment are both arranged in parallel, and compared to the first embodiment, the jack surrounded by the contact cantilevers in the embodiment does not form a necking structure, and the contact cantilever and the pin have small elastic abutting force and low contact reliability.
The third embodiment of the high-speed connector of the present invention is different from the first embodiment of the high-speed connector in that the position where the two contact cantilevers in the first cantilever pair are integrally connected is clamped by the two contact cantilevers of the second cantilever, so that the first and second cantilever pairs are fixed. In other embodiments, the location where the two contact cantilevers of the second cantilever pair are integrally connected is clamped by the two contact cantilevers of the first cantilever.
