Description
Technical Field
The invention relates to the technical field of electric connector manufacturing, in particular to an IO connector female socket with high insertion and assembly stability.
Background
At present, the information industry is developed at a high speed, the electronic technology is continuously improved, the updating speed of electronic products is accelerated, and new electronic products are continuously emerged. This makes the use of IO electrical connectors as a base electronic component more and more frequent. I represents in (input), O represents out (output), and I/O represents input/output interface on the computer. The IO electric connector is used for supporting transmission of high-speed serial differential signals, and meanwhile, high density, high mechanical robustness and easy assembly are combined with excellent shielding performance and signal integrity. The IO electrical connectors are mounted around the wafer system and employ a differential pair configuration.
The IO connector female socket and the IO connector male socket are mutually inserted and matched to cooperatively execute a transmission process of a signal. In the prior art, an IO connector female socket includes an outer housing and a socket tongue. The socket tongue is built in and fixed in the outer shell and comprises an upper terminal group, a lower terminal group and an insulating plastic body. The upper terminal group and the lower terminal group are inserted and fixed in the insulating plastic body. The upper terminal group comprises a plurality of upper-row signal terminals which are all communicated with the PCB. The lower terminal group comprises a lower row of signal terminals and a ground terminal which are both communicated with the PCB. The number of the ground terminals is at least 2, and the ground terminals are arranged side by side with the lower row of the signal terminals. In order to ensure the stability of the posture of the female IO connector receptacle after being inserted into the male IO connector receptacle, a conventional method is to symmetrically provide left and right limiting grooves on the left and right side walls of the insulating plastic body, and correspondingly, the left and right side walls of the male IO connector receptacle are symmetrically provided with left and right extending elastic arms adapted to the left and right limiting grooves and right extending elastic arms adapted to the right limiting grooves. After the IO connector female seat and the IO connector male seat are mutually inserted and matched, the left extending elastic arm and the right limiting groove are respectively and positively arranged in the left limiting groove and the right limiting groove to realize the locking of the axial relative displacement motion of the left extending elastic arm and the right extending elastic arm. However, the left limiting groove and the right limiting groove are directly formed on the insulating plastic body. Because the insulating plastic body is formed by plastic injection molding, the structural strength of the insulating plastic body is weak, namely the structural strength of the left limiting groove and the right limiting groove is limited, so that the insertion and matching binding force and the stability between the IO connector male seat and the IO connector female seat are limited inevitably, and the subsequent phenomenon of breaking away is easy to occur due to the action of an exciting force; moreover, the insulating plastic body has poor self wear resistance, and after the male seat of the IO connector and the female seat of the IO connector are inserted and pulled for several times, the left limiting groove and the right limiting groove are easily worn, so that the insertion and matching precision between the male seat of the IO connector and the female seat of the IO connector is inevitably influenced, and the normal execution of a signal transmission process is further influenced (the phenomenon of poor contact is easily caused); in addition, the wiring terminal is independently formed in the insulating plastic body, the binding force between the wiring terminal and the insulating plastic body is weaker, and the phenomena of position change and movement are very easy to occur under the action of external force, so that the grounding stability of the male seat of the IO connector is influenced. Thus, a skilled person is urgently needed to solve the above problems.
Disclosure of Invention
Therefore, in view of the above-mentioned problems and drawbacks, the present invention provides a method for manufacturing a female IO connector with high insertion stability, which comprises collecting relevant data, evaluating and considering the data, and performing experiments and modifications by a technician engaged in the industry for years.
In order to solve the technical problem, the invention relates to an IO connector female seat with high insertion and matching stability, which is inserted and matched with an IO connector male seat. The high-insertion-stability IO connector female seat comprises an outer metal shell and a socket tongue. The socket tongue is internally arranged and fixed in the outer metal shell and comprises an upper terminal group, a lower terminal group and a secondary floating insulating plastic body. The upper terminal group and the lower terminal group are embedded in the secondary Moliding insulating plastic body. The upper terminal group comprises an upper row of signal terminal units and an upper primary floating insulating plastic body. The upper row of signal terminal units are embedded in the upper primary Moliding insulating plastic body. The upper row signal terminal unit is composed of a plurality of upper row signal terminals which are arranged side by side along the left-right direction in sequence and are all communicated with the PCB. The lower terminal group comprises a lower row of signal terminal units and a lower arranged primary Moliding insulating plastic body. The lower row of signal terminal units are embedded in the primary Moliding insulating plastic body arranged below. The lower-row signal terminal unit is composed of a plurality of lower-row signal terminals which are arranged side by side along the left-right direction in sequence and are communicated with the PCB. In addition, the socket tongue further comprises an auxiliary reinforcement unit. The auxiliary reinforcement unit is embedded in the secondary Moliding insulating plastic body and clamped between the upper terminal group and the lower terminal group. The auxiliary reinforcement unit is composed of a left-placed metal auxiliary reinforcement and a right-placed metal auxiliary reinforcement which are symmetrically arranged along the left-right direction. The left metal auxiliary reinforcing part is composed of a left flat insertion reinforcing section, a left arc bending transition section and a left flat grounding terminal section in sequence. When the lower sliding insulating plastic body is injection molded, the left horizontal grounding terminal is embedded in the lower sliding insulating plastic body and is communicated with the PCB. After the secondary Moliding insulating plastic body is injection molded, the left-placed flat insertion reinforcing section and the left-placed arc-shaped bending transition section are embedded in the secondary Moliding insulating plastic body. The right metal auxiliary reinforcing part is composed of a right horizontal insertion reinforcing section, a right arc bending transition section and a right horizontal grounding terminal section in sequence. When the lower Moliding insulating plastic body is injection molded, the right horizontal grounding terminal is embedded in the lower Moliding insulating plastic body and is communicated with the PCB. After the secondary Moliding insulating plastic body is injection molded, the right-placed flat insertion reinforcing section and the right-placed arc-shaped bending transition section are embedded in the secondary Moliding insulating plastic body. The left horizontal insertion reinforcing section and the right horizontal insertion reinforcing section are respectively connected with the ground through the left horizontal grounding terminal section and the right horizontal grounding terminal section in a one-to-one correspondence mode. A left-mounted locking groove extends rightwards from the left side wall of the left-mounted flat insertion reinforcing section. A right-positioned locking groove extends leftwards from the right side wall of the right-positioned horizontally-arranged insertion reinforcing section. After the left metal auxiliary reinforcing part and the right metal auxiliary reinforcing part are embedded in the secondary Moliding insulating plastic body, the left locking groove and the right locking groove are exposed out of the secondary Moliding insulating plastic body.
As a further improvement of the technical scheme of the invention, in the process of injection molding the Moliding insulating plastic body at the lower part, a left clamping arm, a right clamping arm, a left limiting column and a right limiting column are respectively molded on the Moliding insulating plastic body, correspondingly, in the process of injection molding the Moliding insulating plastic body at the upper part, a left clamping notch matched with the left clamping arm, a right clamping notch matched with the right clamping arm, a left limiting hole matched with the left limiting column and a right limiting hole matched with the right limiting column are respectively molded on the Moliding insulating plastic body at the upper part.
As a further improvement of the technical scheme of the invention, at least one left limiting notch extends leftwards from the right side wall of the left flat insertion reinforcing section, and correspondingly, left limiting bulges matched with the left limiting notches in number, shape and position extend leftwards from the left side wall of the left buckling arm. At least one right position limiting notch extends rightwards from the left side wall of the right position flat insertion reinforcing section, and correspondingly, right position limiting bulges matched with the number, the shape and the position of the right position limiting notches extend rightwards continuously from the right side wall of the right position buckling arm. When the left horizontal grounding terminal section is embedded in place by the Moliding insulating plastic body at the lower part, the left limiting bulge is arranged in the left limiting notch. When the right horizontal grounding terminal section is embedded in place by the Moliding insulating plastic body at the lower part, the right limiting bulge is just arranged in the right limiting notch.
Compared with the IO connector female socket with the traditional design structure, in the technical scheme disclosed by the invention, the left-placed metal auxiliary reinforcing piece and the right-placed metal auxiliary reinforcing piece are respectively arranged on two sides of the socket tongue, and the left-placed horizontal insertion reinforcing section and the right-placed horizontal insertion reinforcing section are respectively provided with the left-placed locking groove and the right-placed locking groove in a one-to-one correspondence manner. The left metal auxiliary reinforcing piece and the right metal auxiliary reinforcing piece have high structural strength, so that when the IO connector female seat and the IO connector male seat are inserted and matched in place, the left locking groove and the right locking groove cooperatively act to limit axial displacement movement of the IO connector male seat, good insertion and matching stability of the IO connector female seat relative to the IO connector male seat is ensured, and the phenomenon that the IO connector female seat is disconnected relative to the IO connector male seat due to excitation force or accidental touch force in practical application is avoided. Because the left metal auxiliary reinforcing part and the right metal auxiliary reinforcing part have higher wear-resisting strength, when the inserting and matching operation of the IO connector female seat and the IO connector male seat is executed, the inserting and matching force directly acts on the left metal auxiliary reinforcing part and the right metal auxiliary reinforcing part instead of the secondary Moliding insulating plastic body with extremely weak abrasion resistance, so that the frequency of executing the repeated inserting and pulling action of the IO connector female seat relative to the IO connector male seat is greatly promoted, higher inserting and matching precision between the IO connector male seat and the IO connector female seat is ensured, and the normal execution of a signal transmission process is ensured.
In addition, in the technical scheme, the left horizontal grounding terminal section and the right horizontal grounding terminal section are used for realizing the grounding function of the IO connector together, the left horizontal grounding terminal section and the right horizontal grounding terminal section are respectively formed by directly extending the left horizontal insertion enhancing section and the right horizontal insertion enhancing section which play the insertion enhancing role in a one-to-one correspondence mode, an organic stress body is formed between the left horizontal grounding terminal section and the left horizontal insertion enhancing section through the transition connection function of the left arc-shaped bending transition section, and an organic stress body is formed between the right horizontal grounding terminal section and the right horizontal insertion enhancing section through the transition connection function of the right arc-shaped bending transition section. After the IO connector female socket is formed, the left-side flat-placed grounding terminal section not only receives the bonding force of the primary Moliding insulating plastic body, but also receives the acting force from the left-side flat-placed insertion reinforcing section embedded in the secondary Moliding insulating plastic body. The right horizontal grounding terminal section not only receives the bonding force of the primary Moliding insulating plastic body, but also receives the acting force from the right horizontal insertion reinforcing section embedded in the secondary Moliding insulating plastic body, so that the bonding strength of the left horizontal grounding terminal section and the right horizontal grounding terminal section in the IO connector female seat after molding is effectively improved, the phenomenon of relative position change caused by external force action subsequently is avoided, and the grounding stability of the IO connector male seat is further ensured.

Detailed Description
In the description of the present invention, it is to be understood that the terms "rear", "front", "upper", "lower", "front", "rear", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience in describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.
As is known, the female IO connector socket and the male IO connector socket are mutually plugged and cooperate to realize signal transmission.
In the following, the contents of the present invention are further described in detail with reference to specific embodiments, and fig. 1 and fig. 2 respectively show a schematic perspective view and an explosion view of a female seat of an IO connector with high insertion stability in the present invention, and it can be known that the female seat mainly comprises an outer metal housing 1 and a socket tongue 2. When the socket tongue 2 is formed, the whole socket tongue is inserted into the outer metal shell 1.
As shown in fig. 3 and 4, the socket tongue 2 is mainly composed of an upper terminal group 21, a lower terminal group 22, and a secondary floating insulating plastic body 23. Wherein, the upper terminal group 21 and the lower terminal group 22 are embedded in the secondary Moliding insulating plastic body 23. As shown in fig. 5, the upper terminal group 21 includes an upper row of signal terminal units 211 and a primary attaching insulating plastic body 212. The upper row signal terminal unit 211 is embedded in the upper primary moving insulating plastic body 212. The upper row signal terminal unit 211 is composed of a plurality of upper row signal terminals 2111 which are arranged side by side in order along the left-right direction and are all electrically connected to the PCB board. As shown in fig. 6, the lower terminal group 22 includes a lower row of signal terminal units 221 and a lower-mounted primary Moliding insulating plastic body 222. The lower row signal terminal unit 221 is embedded in the lower primary floating insulating plastic body 222. The lower signal terminal unit 221 includes a plurality of lower signal terminals 2211 that are arranged side by side in the left-right direction and electrically connected to the PCB. The upper row signal terminal 2111 and the lower row signal terminal 2211 are opposed to each other in the vertical direction, and in practical use of the IO connector female socket, the two terminals execute signal transmission processes independently of each other.
Furthermore, as shown in fig. 3 and 4, an auxiliary reinforcement unit 24 is further added in the socket tongue 2 to ensure good insertion stability between the female IO connector seat and the male IO connector seat. Specific embodiments are recommended as follows: the auxiliary reinforcement unit 24 is directly embedded in the secondary Moliding insulating plastic body 23 and is sandwiched between the upper terminal group 21 and the lower terminal group 22. As shown in fig. 7, the auxiliary reinforcement unit 24 is constituted by left-hand metallic auxiliary reinforcements 241 and right-hand metallic auxiliary reinforcements 242 which are symmetrically disposed in the left-right direction. As shown in fig. 10 and 11, the left-disposed metal auxiliary reinforcement 241 is composed of a left-disposed flat insertion reinforcement section 2411, a left-disposed curved bent transition section 2412, and a left-disposed flat ground terminal section 2413 in this order. As shown in fig. 12 and 13, the right metal auxiliary reinforcement 242 is composed of a right horizontally disposed insertion reinforcement section 2421, a right arcuately bent transition section 2422 and a right horizontally disposed ground terminal section 2423 in sequence. As shown in fig. 14, 15 and 16, after the next injection molding of the floating insulating plastic body 222, the left-disposed horizontal ground terminal segment 2413 is embedded therein and conducted with the PCB. After the secondary Moliding insulating plastic body 23 is injection molded, the left-disposed flat insertion enhancement section 2411 and the left-disposed arc-shaped bending transition section 2412 are both embedded therein. When the bottom mounted floating insulating plastic body 222 is injection molded, the right mounted horizontal ground terminal 2423 is embedded therein and is electrically connected to the PCB. After the secondary Moliding insulating plastic body 23 is injection molded, the right horizontally disposed insertion enhancement section 2421 and the right arcuately bent transition section 2422 are both embedded therein. The left-side horizontally-disposed insertion enhancement section 2411 and the right-side horizontally-disposed insertion enhancement section 2421 are respectively connected to ground via the left-side horizontally-disposed ground terminal section 2413 and the right-side horizontally-disposed ground terminal section 2423 in a one-to-one correspondence manner. A left locking groove 24111 extends rightward from the left side wall of the left flat insertion enhancement section 2411. A right locking groove 24211 extends leftwards from the right side wall of the right horizontal insertion reinforcing section 2421. Thus, on the one hand, after the left metal auxiliary reinforcement 241 and the right metal auxiliary reinforcement 242 are embedded in the secondary Moliding insulating plastic body 23, the left locking groove 24111 and the right locking groove 24211 are both exposed outside the secondary Moliding insulating plastic body 23. When the female IO connector seat and the male IO connector seat are in the inserted and matched position, the left locking groove 24111 and the right locking groove 24211 cooperate to limit the axial displacement motion of the male IO connector seat, so that the female IO connector seat is ensured to have better insertion and matching stability relative to the male IO connector seat, and the phenomenon that the female IO connector seat is separated relative to the male IO connector seat due to excitation force or accidental touch force in practical application is avoided; on the other hand, the left metal auxiliary reinforcing part 241 and the right metal auxiliary reinforcing part 242 have higher wear resistance, so that the repeated plugging and unplugging actions of the IO connector female socket relative to the IO connector male socket are greatly promoted and executed, higher plugging and mating precision is guaranteed between the IO connector male socket and the IO connector female socket, and the signal transmission process is normally executed.
In addition, it should be noted that, in the above technical solution, the left and right horizontal ground terminal segments 2413 and 2423 are used to jointly implement the grounding function of the IO connector, and the left and right horizontal ground terminal segments 2413 and 2423 are respectively and correspondingly formed by directly extending the left and right horizontal insertion enhancement segments 2411 and 2421, which play a role in insertion enhancement, respectively, and the transition connection function of the left and right curved bending transition segments 2412 is used to form an organic stressed body between the left and right horizontal ground terminal segments 2413 and 2311, and the transition connection function of the right curved bending transition segment 2422 is used to form an organic stressed body between the right and right horizontal ground terminal segments 2423 and 2421. After the IO connector female housing is formed, the left-side flat ground terminal 2413 not only receives the bonding force of the primary Moliding insulating plastic body 222, but also receives the acting force from the left-side flat insertion reinforcing section 2411 embedded in the secondary Moliding insulating plastic body 23. The right-side horizontal grounding terminal segment 2421 not only receives the bonding force of the primary Moliding insulating plastic body 222, but also receives the acting force from the right-side horizontal insertion reinforcing segment 2421 embedded in the secondary Moliding insulating plastic body 23, so that the bonding strength of the left-side horizontal grounding terminal segment 2413 and the right-side horizontal grounding terminal segment 2423 in the IO connector female seat after molding is effectively improved, the phenomenon of relative position change caused by external force action subsequently is avoided, and the grounding stability of the IO connector male seat is further ensured.
The forming process steps of the socket tongue 2 are roughly as follows:
1) the molding of the upper terminal packet 21 is realized. Arranging a plurality of upper-row signal terminals 2111 in a first mold cavity in sequence, then injecting a large amount of molten plastic into the cavity, condensing and molding into the upper once-built Moliding insulating plastic body 212, wherein at the moment, each upper-row signal terminal 2111 is stably embedded in the upper once-built Moliding insulating plastic body 212;
2) the molding of the lower terminal packet 22 is achieved. Arranging a plurality of lower row signal terminals 2211, a left horizontal grounding terminal segment 2413 and a right horizontal grounding terminal segment 2423 in a second mold cavity in sequence, then injecting a large amount of molten plastic into the cavity, condensing and molding into a primary Moliding insulating plastic body 222, wherein at the moment, each lower row signal terminal 2211, each left horizontal grounding terminal segment 2413 and each right horizontal grounding terminal segment 2423 are stably embedded in the primary Moliding insulating plastic body 222;
3) the upper terminal packet 21 and the lower terminal packet 22 are assembled with each other. The upper terminal sub-group 21 and the lower terminal sub-group 22 are assembled into a whole to form a component;
4) final shaping of the socket tongue 2. And (3) placing the components into a third mold cavity, then injecting a large amount of molten plastic into the cavity, condensing and molding into a secondary Moliding insulating plastic body 23, wherein at the moment, the left-placed flat insertion reinforcing section 2411, the left-placed arc-shaped bending transition section 2412, the right-placed flat insertion reinforcing section 2421 and the right-placed arc-shaped bending transition section 2422 are stably embedded in the secondary Moliding insulating plastic body 23.
As shown in fig. 4, 8 and 9, in the process of performing injection molding on the primary Moliding insulating plastic body 222, a left-side snap arm 2221, a right-side snap arm 2222, a left-side limiting post 2223 and a right-side limiting post 2224 are respectively formed thereon, and correspondingly, in the process of performing injection molding on the primary Moliding insulating plastic body 212, a left-side snap notch 2121 adapted to the left-side snap arm 2221, a right-side snap notch 2122 adapted to the right-side snap arm 2222, a left-side limiting hole 2123 adapted to the left-side limiting post 2223 and a right-side limiting hole 2124 adapted to the right-side limiting post 2224 are respectively formed thereon. Therefore, on one hand, in the process of molding the secondary Moliding insulating plastic body 23, by adopting the technical scheme for setting, the upper terminal group 21 can be effectively ensured to have higher position precision and certain binding force relative to the lower terminal group 22, and the phenomenon that the upper terminal group and the lower terminal group are mutually separated due to the action of impact force in the process of injecting molten plastic is avoided; on the other hand, when the insertion and assembly operation is completed, the upper terminal group 21 and the lower terminal group 22 can have higher relative position accuracy, so that good alignment accuracy and respective relative position accuracy between the upper row signal terminals 2111 and the lower row signal terminals 2211 are ensured, and the stability and reliability of the conduction between the female IO connector seat and the male IO connector seat are ensured.
Fig. 17 shows an assembly diagram of the auxiliary reinforcement unit relative to the lower terminal group in the first embodiment of the IO connector female seat with high insertion and matching stability according to the present invention, and it can be seen that after the next molding of the Moliding insulating plastic body 222 is completed, the extended left-side latch arm 2221 and the extended right-side latch arm 2222 correspondingly abut against the right-side wall of the left-side planar insertion and matching reinforcement section 2411 and the left-side wall of the right-side planar insertion and matching reinforcement section 2421 one by one, so as to avoid the position change phenomenon of the right-side wall of the left-side planar insertion and matching reinforcement section 2411 and the right-side planar insertion and matching reinforcement section 2421 due to the impact force of the molten plastic in the subsequent injection molding process of the secondary Moliding insulating plastic body 23.
Fig. 18 shows an assembly diagram of an auxiliary reinforcement unit relative to a lower terminal group in a second embodiment of the female IO connector with high insertion stability according to the present invention, which is different from the first embodiment in that: at least one left position-limiting notch 24112 is extended leftwards from the right side wall of the left-side horizontally-arranged insertion-matching reinforcing section 2411, and correspondingly, left position-limiting protrusions 22211 matched with the left position-limiting notches 24112 in number, shape and position are extended leftwards from the left side wall of the left-side buckling arm 2221. At least one right position limiting notch 24212 extends rightwards from the left side wall of the right position flat insertion reinforcing section 2421, and correspondingly, right position limiting protrusions 22221 matched with the right position limiting notches 24212 in number, shape and position extend rightwards continuously from the right side wall of the right position buckling arm 2222. When the left-side horizontal ground terminal 2413 is placed under the primary sliding insulating plastic 222 and then inserted in place, the left-side position-limiting protrusion 22211 is placed in the left-side position-limiting notch 24112. When the right-side horizontal grounding terminal section 2423 is placed in the primary Moliding insulating plastic body 222, the right-side limiting protrusion 22221 is just placed in the right-side limiting notch 24212. Therefore, the limit value of the axial force that can be borne by the left-side horizontally-arranged insertion enhancement section 2411 and the right-side horizontally-arranged insertion enhancement section 2421 in the primary Moliding insulating plastic body 222 placed below can be further increased, and the deflection phenomenon caused by the lateral force acting on the left-side horizontally-arranged insertion enhancement section 2411 and the right-side horizontally-arranged insertion enhancement section 2421 can be effectively avoided, so that the IO connector male seat in the insertion and distribution state is finally ensured to have good grounding performance.
