Description

Technical Field

[0001] This invention relates to an electrical connector, and more particularly to an electrical connector that is both anti-reverse and grounded. Background Technology

[0002] In order to fix two connector bodies together, there are usually two methods: the first is to fix them by setting a snap-fit, and the second is to use injection molding.

[0003] The first method can be found in Chinese patent application number CN201220213207.3, which discloses an electrical connector including an insulating body, a terminal module housed within the insulating body, and a metal shell covering the outer perimeter of the insulating body. The terminal module includes several conductive terminals and a plastic block injection molded onto the conductive terminals. The insulating body includes a top wall and a bottom wall corresponding to the top wall. The top wall and the bottom wall are respectively provided with first retaining blocks. The plastic block is provided with several second retaining blocks on its upper and lower sides, which are engaged with the first retaining blocks. In the aforementioned structure, since both the first retaining blocks and the second retaining blocks are made of plastic, during the process of interlocking, the first retaining blocks and the second retaining blocks will have abutting force against each other until deformation and then interlocking. This will result in stress concentration, making it very easy for them to crack or break during repeated interlocking.

[0004] The second method can be found in Chinese patent application number CN201410730382.3, which discloses a USBTYPE-C connector, including an insulating body, a terminal module housed within the insulating body, and a metal shell covering the outer periphery of the insulating body. The terminal module includes multiple conductive terminals and a plastic block injection molded onto the multiple conductive terminals. The insulating body is then injection molded onto the plastic block, thereby fixing the insulating body and the plastic block.

[0005] With the development of connectors, the required transmission rate has increased from 480Mbps for USB 2.0 to 10Gbps for USB TYPE-C, and some products even require more than 15Gbps. Therefore, the optimization of high-frequency performance has become increasingly important. One method is to bridge the grounding terminals with a grounding plate to achieve a common ground and increase the grounding loop, thereby improving high-frequency performance. For example, Chinese patent application number CN201720476632.4 discloses an electrical connector including an insulating body, a grounding plate, a terminal module housed in the insulating body, and a metal shell covering the outer perimeter of the insulating body. The terminal module includes multiple conductive terminals and a plastic block injection molded on the multiple conductive terminals. The multiple conductive terminals include a grounding terminal, and the grounding plate is used to connect with the grounding terminal to achieve grounding.

[0006] In summary, those skilled in the art have adopted a singular approach to solving the numerous problems existing in current electrical connectors. For example, if two parts need to be fixed, they try to find a way to fix them; if a grounding loop needs to be added, they simply add a grounding plate. They lack the mindset and ability to integrate various technical means in the industry.

[0007] Therefore, it is necessary to design a new electrical connector to overcome the above problems. Summary of the Invention

[0024] Compared with the prior art, the present invention has the following beneficial effects: This invention abandons the conventional design thinking of those skilled in the art. It utilizes the fact that both the grounding component and the metal component are made of metal. The grounding component has an abutting part that abuts against the grounding terminal and an extension part that abuts against the metal component. The metal component has a blocking part that prevents the extension part from moving backward.

[0026] To facilitate a better understanding of the purpose, structure, features, and effects of this invention, the invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0027] To facilitate a better understanding of the technical solution of the present invention, the X-axis in the three-dimensional coordinate axes in the accompanying drawings is defined as a third direction, which is the front-back direction; the Y-axis is defined as a first direction, which is the left-right direction; and the Z-axis is defined as a second direction, which is the up-down direction.

[0028] like Figures 1 to 10 As shown, the electrical connector 1 of the present invention is used to mate with a mating connector (not shown) along the front-to-back direction. The electrical connector 1 includes an insulating body 11, a terminal module 12 assembled on the insulating body 11, a grounding member 13 fixed to the terminal module 12, and a metal member 14 fixed to the insulating body 11. In this embodiment, the insulating body 11 is injection molded onto the metal member 14; in other embodiments, the insulating body 11 is assembled onto the metal member 14.

[0029] like Figure 1 , Figures 7 to 8 As shown, the insulating body 11 has a front end face 111, a rear end face 112, a slot 113 recessed from the front end face 111, a receiving groove 114 recessed from the rear end face 112, two guide grooves 115 located on the left and right sides of the slot 113, upper and lower opposing wall portions 116 and bottom wall 117, and a first groove 118 recessed from the wall portion 116 along the vertical direction. The slot 113 and the receiving groove 114 are connected in the front-rear direction. The wall portion 116 and the bottom wall 117 are located above and below the slot 113 and the receiving groove 114, respectively. The terminal module 12 is received in the receiving groove 114, and the first groove 118 communicates with the receiving groove 114. The docking connector (not shown) is provided with a tongue plate (not shown) and guide portions (not shown) located on the left and right sides of the tongue plate (not shown). Two guide grooves 115 pass through the slot 113 in the left and right directions respectively. The guide grooves 115 are used to guide the guide portions (not shown) to dock, and the slot 113 is used to dock with the tongue plate (not shown). The height of the slot 113 along the vertical direction is less than the height of the guide groove 115, and the height of the tongue plate (not shown) is less than the height of the guide portion (not shown). This helps prevent misalignment when the electrical connector 1 and the mating connector (not shown) are mated. The center line L1 of the slot 113 is higher than the center line L2 of the guide groove 115, preventing the mating connector (not shown) from being inserted backwards into the electrical connector 1. The fact that the height of the slot 113 is less than the height of the guide groove 115 along the vertical direction, and that the center line L1 of the slot 113 is higher than the center line L2 of the guide groove 115, are both arranged together and cooperate with each other, which helps the electrical connector 1 and the mating connector (not shown) to accurately and correctly mate, further ensuring stable electrical contact between the two.

[0030] like Figure 1 , Figures 7 to 10 As shown, the terminal module 12 includes a plastic block 121 and a plurality of conductive terminals 122 fixed to the plastic block 121. The grounding member 13 is fixed to the plastic block 121. The grounding member 13 has a main body 131, a fixing groove 132 recessed from the main body 131 along the vertical direction, and a plurality of abutment portions 133 and a plurality of extension portions 134 connecting the main body 131. In other embodiments, the grounding member 13 has one abutment portion 133; in other embodiments, the grounding member 13 has one extension portion 134. The extension portion 134 extends from the main body 131 in the front-rear direction and is located on one side of the fixing groove 132. The extension portion 134 has an elastic portion 1341 connecting to the main body 131 and a stop portion 1342 connecting to the elastic portion 1341. A portion of the elastic portion 1341 is received in the first groove 118, which provides elastic deformation space for the elastic portion 1341.

[0031] like Figure 1 , Figure 4 , Figures 8 to 10As shown, the plastic block 121 includes a support portion 1211, multiple isolation portions 1212 connecting the front and rear ends of the support portion 1211, a receiving groove 1213 located between two adjacent isolation portions 1212 in the left-right direction, a side wall 1214 connecting the multiple isolation portions 1212, a fixing portion 1215 protruding upward from the support portion 1211, and a receiving groove 1216 recessed from the support portion 1211. The support portion 1211 abuts upward against the main body portion 131 to support the grounding member 13. Multiple isolation portions 1212 are arranged in a left-right direction. The multiple isolation portions 1212 connected to the rear end of the support portion 1211 are collectively connected to the sidewall 1214. In this embodiment, some of the isolation portions 1212 are recessed in a second groove 12121 along the vertical direction, and a portion of the elastic portion 1341 is received in the second groove 12121. The second groove 12121 provides elastic deformation space for the elastic portion 1341. In other embodiments, each isolation portion 1212 is recessed in the second groove 12121 along the vertical direction, and the elastic portion 1341... A portion of the elastic part 1341 is housed in the second groove 12121, which provides elastic deformation space for the elastic part 1341. In this embodiment, the receiving groove 1213 houses two abutting parts 133; in other embodiments, the receiving groove 1213 houses one abutting part 133. The anti-reverse part 1342 extends from the elastic part 1341 in the front-back direction, and when viewed from the top-bottom direction, the anti-reverse part 1342 and the side wall 1214 part 116 are partially projected to overlap. The side wall 1214 has an overpressure prevention function for the anti-reverse part 1342. The fixing part 1215 is fixed to the fixing groove 132, and the receiving groove 1216 surrounds the fixing part 1215. The receiving groove 1216 has an inner wall surface 12161 connected to the fixing part 1215, and the receiving groove 1216 is used to receive adhesive residue or impurities.

[0032] like Figure 1 , Figures 7 to 8 , Figure 10As shown, each conductive terminal 122 is provided with a contact portion 1221, a solder portion 1223, and a connecting portion 1222 connecting the contact portion 1221 and the solder portion 1223. The contact portion 1221 is exposed in the slot 113 and is used for electrical connection with the mating terminal of the mating connector (not shown). The connecting portion 1222 is fixed to the plastic block 121, and the solder portion 1223 is used for soldering to a circuit board (not shown). In this embodiment, the plurality of conductive terminals 122 include a plurality of signal terminals 122S and a plurality of ground terminals 122G arranged in the left-right direction. In other embodiments, the plurality of conductive terminals 122 include a plurality of signal terminals 122S and a ground terminal 122G arranged in the left-right direction. Viewed from top to bottom, the connecting portion 1222 of the signal terminal 122S is partially blocked by the isolation portion 1212, and the connecting portion 1222 of the ground terminal 122G is partially exposed in the receiving groove 1213.

[0033] like Figures 7 to 9 As shown, the abutting portion 133 abuts against the grounding terminal 122G, and the extension portion 134 abuts against the metal part 14, realizing that the grounding terminal 122G, the grounding part 13, and the metal part 14 are grounded together. Specifically, every two abutting portions 133 extend from the main body portion 131 along opposite sides in the front-rear direction and abut against the same grounding terminal 122G, and a single grounding loop is realized through the main body portion 131, which helps to increase the grounding effect of the grounding part 13 and the grounding terminal 122G. In this embodiment, the abutting portion 133 abuts downward against the grounding terminal 122G, and the extension portion 134 abuts upward against the metal part 14, which helps to partially cancel out the forces exerted on the main body portion 131 by the grounding terminal 122G and the metal part 14 in the up-down direction, making the grounding part 13 and the plastic block 121 more stable and less prone to loosening. In other embodiments, the abutting portion 133 abuts forward against the grounding terminal 122G, and the extension portion 134 abuts backward against the metal member 14. This facilitates the partial cancellation of the forces exerted on the main body portion 131 by the grounding terminal 122G and the metal member 14 along the front-back direction, making the grounding member 13 and the plastic block 121 more stable and less prone to loosening.

[0034] like Figures 1 to 2 , Figure 5 , Figures 8 to 9As shown, the metal part 14 has a plate portion 141, multiple protrusions 142 connecting the plate portion 141, two fastening grooves 143 recessed from the plate portion 141 in the vertical direction, and multiple positioning portions 144 bent downward from the plate portion 141. The wall portion 116 is injection molded onto the plate portion 141, and the thickness of the wall portion 116 is greater than the thickness of the plate portion 141. The wall portion 116 and the plate portion 141 are coplanar at the end away from the plastic block 121 in the vertical direction. The elastic portion 1341 elastically abuts against the plate portion 141 upward. The plate portion 141 is provided with a plurality of covering portions 1411 and a plurality of stopping portions 1412. In this embodiment, the stopping portion 1412 is a through hole that penetrates the covering portion 1411 in the vertical direction. The stopping portion 1412 communicates with the first groove 118 and accommodates the anti-retraction portion 1342. In other embodiments, the stopping portion 1412 is a protrusion that connects to the covering portion 1411. The stopping portion 1412 is located in the first groove 118. The covering portion 1411 is located between two adjacent protrusions 142. The stopping portion 1412 prevents the anti-retraction portion 1342 from moving backward, thereby preventing the plastic block 121 from exiting the insulating body 11. Specifically, the thickness of the stop portion 1412 in the vertical direction is greater than the thickness of the anti-reverse portion 1342. This ensures that even if the anti-reverse portion 1342 shifts in the vertical direction after being subjected to the abutment force of the stop portion 1412 during anti-reverse movement, it can still maintain contact with the stop portion 1412. The stop portion 1412 has a generally planar stop surface 14121, and the anti-reverse portion 1342 has a generally planar anti-reverse surface 13421. The stop surface 14121 prevents the anti-reverse surface 13421 from shifting backward, which helps to enhance the positive force of the anti-reverse portion 1342. This ensures that the stop surface 14121 abuts against the anti-reverse surface 13421 in the front-back direction during anti-reverse movement, and the extension portion 134 is less prone to kneeling.

[0035] like Figures 1 to 2 , Figure 7As shown, the protrusion 142 is embedded in the wall portion 116. The protrusion 142 has a first step portion 1421 and a second step portion 1422, which helps to increase the contact area between the protrusion 142 and the wall portion 116. The second step portion 1422 extends from the first step portion 1421 in the vertical direction near one end of the plastic block 121, preventing the first step portion 1421 from applying force alone and thus damaging the wall portion 116, which is beneficial for strengthening and fixing the metal part 14 to the wall portion 116. In other embodiments, the plate portion 141 is provided with a cover portion 1411 and a stop portion 1412. The two fastening grooves 143 are respectively located on the left and right sides of the plate portion 141. The fastening grooves 143 communicate with the guide groove 115 in the vertical direction. The mating connector (not shown) is provided with a locking portion (not shown) located on the guide portion (not shown). The fastening groove 143 is used to fasten with the locking portion (not shown). The positioning part 144 passes through the bottom wall 117 and is fixed to the locking part (not shown) in the vertical direction. In summary, the electrical connector 1 of the present invention has the following beneficial effects: 1. The stop portion 1412 and the anti-retraction portion 1342 are displaced backward to prevent the plastic block 121 from exiting the insulating body 11. Since both the grounding component 13 and the metal component 14 are made of metal, compared to the first and second holding blocks in the prior art, the stop portion 1412 and the anti-retraction portion 1342 in this application are less prone to breakage or damage during rearward displacement. The grounding component 13 is provided with an abutment portion 133 and an extension portion 134. The abutment portion 133 abuts against the grounding terminal 122G, and the extension portion 134 abuts against the metal component 14, thereby achieving… While the grounding terminal 122G, grounding component 13, and metal component 14 are grounded together, the extension 134 passes through the insulating body 11 and abuts against the metal component 14, which prevents the plastic block 121 from exiting the insulating body 11. This application breaks through the conventional fixing method of the insulating body 11 and the plastic block 121 in the prior art. It not only solves the problems existing in the prior art, but also realizes the common grounding and anti-backward function of the three through the extension 134 of the grounding component 13, which simplifies the manufacturing process of the grounding component 13 and reduces the production cost.

[0036] 2. Compared to the prior art, where it is difficult to observe the engagement of the first and second latching blocks, leading to inspectors failing to promptly detect the situation where the plastic block 121 and the insulating body 11 are prone to loosening, the blocking portion 1412 of this application is a through hole that accommodates the anti-retraction portion 1342. Inspectors can easily observe whether the anti-retraction portion 1342 is located within the blocking portion 1412, allowing for timely handling of any abnormalities. The elastic portion 1341 elastically abuts against the plate portion 141, achieving grounding while also limiting the elastic deformation range of the elastic portion 1341, which facilitates the accurate accommodation of the anti-retraction portion 1342 within the blocking portion 1412. The thickness of the blocking portion 1412 in the vertical direction is greater than the thickness of the anti-retraction portion 1342, ensuring that the anti-retraction portion 1342 is protected by the blocking portion 1412 during anti-retraction. Even after the contact force is applied, the stop part 1412 can still maintain good contact even if there is a vertical displacement. The stop part 1412 has a generally flat stop surface 14121, and the anti-reverse part 1342 has a generally flat anti-reverse surface 13421. This helps to enhance the positive force of the anti-reverse part 1342 and ensures that the stop surface 14121 abuts against the anti-reverse surface 13421 in the front-back direction when preventing the retraction. The extension part 134 is less likely to experience a kneeling phenomenon. The elastic part 1341 elastically abuts against the plate part 141 and can also provide a reaction force to the anti-reverse part 1342, further preventing the anti-reverse part 1342 from being excessively deformed after being subjected to the force applied by the stop part 1412 and thus avoiding a kneeling phenomenon. Ultimately, this ensures the stability of the stop part 1412 in preventing the anti-reverse part 1342 from moving backward.

[0037] 3. The wall portion 116 is injection molded onto the plate portion 141, which strengthens the structural strength of the wall portion 116. The thickness of the wall portion 116 in the vertical direction is greater than the thickness of the plate portion 141. While meeting the low height requirement of the electrical connector 1, this ensures a sufficiently large injection contact area between the wall portion 116 and the plate portion 141, further guaranteeing the robustness of the injection molding. The plate portion 141 has a through-hole 1412, which is a through hole and connects to the first groove 118. During injection molding, the wall portion 116 and the first groove 118 are respectively formed in the vertical direction. 8. Placing the mold core prevents molten plastic from flowing to the stop portion 1412 and blocking it, ensuring that the anti-reverse function of the stop portion 1412 is not affected. At the same time, since the second groove 12121 provides elastic deformation space for the elastic portion 1341, it helps to ensure that the elastic portion 1341 has sufficient arm length and free elastic deformation. Furthermore, it helps the extension portion 134 to abut against the plate portion 141 to have sufficient positive force and reduce the elastic fatigue of the elastic portion 1341. Ultimately, it ensures that the position of the stop portion 1412 in preventing the backward displacement of the anti-reverse portion 1342 remains stable.

[0038] 4. To achieve a flat and miniaturized connector design, the wall portion 116 along the vertical direction does not cover the plate portion 141. Instead, the wall portion 116 and the plate portion 141 are coplanar at the end away from the plastic block 121 along the vertical direction, exposing the plate portion 141 above the wall portion 116. The plate portion 141 is provided with a cover portion 1411, which is connected to the stop portion 1412. The portion of the cover portion 1411 at the location of the first groove 118 along the vertical direction is not covered by the wall portion 116, making it easy to loosen and lift up. The protrusion 142 is embedded in the wall portion 116, which helps to ensure the stability of the fixation between the plate portion 141 and the wall portion 116. The cover portion 1411 along the left and right direction is located between two adjacent protrusions 142. The protrusions 142 on both sides can reinforce the structure around the cover portion 1411 and the stability of the wall portion 116, further ensuring the stability of the stop portion 1342 in the stop portion 1412 when it moves backward.

[0039] 5. The metal part 14 is provided with a plurality of protrusions 142, each protrusion 142 abutting against the wall part 116. The protrusion 142 is provided with a first step 1421 and a second step 1422, which helps to increase the contact area between the protrusion 142 and the wall part 116. The second step 1422 extends from the first step 1421 in the vertical direction near one end of the plastic block 121, which avoids the first step 1421 applying force alone and thus prying the wall part 116, and helps to fix the wall part 116 and the metal part 14 securely.

[0040] 6. When the stop part 1412 stops the back movement of the anti-reverse part 1342, the extension part 134 will be deformed by force, which will affect the stability of the part of the grounding member 13 connected to the extension part 134 in the front-back direction and the plastic block 121. The grounding member 13 is provided with a fixing groove 132. The extension part 134 in the front-back direction is located on one side of the fixing groove 132. The fixing groove 132 is used to fix with the fixing part 1215 of the plastic block 121. This helps to protect the part of the grounding member 13 connected to the extension part 134 in the front-back direction from the deformation of the extension part 134. It can provide a stable abutting force for the extension part 134 to abut against the stop part 1412.

[0041] 7. The plastic block 121 is provided with a storage groove 1216 recessed in the vertical direction from the support part 1211. The storage groove 1216 surrounds the fixing part 1215. The storage groove 1216 is provided with an inner wall surface 12161 connected to the fixing part 1215. This ensures that when the fixing part 1215 is fixed to the fixing groove 132, if the main body part 131 scrapes against the fixing part 1215, the resulting glue debris can be directly collected in the storage groove 1216. This avoids the accumulation of glue debris on the support part 1211, which would cause a large gap between the support part 1211 and the main body part 131, thereby affecting the fixation of the fixing part 1215 and the fixing groove 132.

[0042] 8. Two adjacent isolation portions 1212 in the left-right direction have two abutting portions 133. The isolation portions 1212 can isolate the abutting portions 133 and also ensure the structural strength of the plastic block 121. The isolation portions 1212 are recessed in the up-down direction with a second groove 12121. A portion of the elastic portion 1341 is received in the second groove 12121. The second groove 12121 provides elastic deformation space for the elastic portion 1341, which is conducive to the free extension and contraction of the extension portion 134, maintaining elasticity, and ensuring that the position of the stop portion 1412 that stops the backward displacement of the anti-reverse portion 1342 remains stable.

[0043] 9. Since the insulating body 11 fixes the metal part 14, the metal part 14 can strengthen the structural strength of the insulating body 11. The insulating body 11 is provided with a guide groove 115 that connects to the slot 113 in the left-right direction for guiding the guide part (not shown) of the docking connector (not shown) to dock. The metal part 14 is provided with a fastening groove 143 that connects to the guide groove 115 in the up-down direction for the locking part (not shown) of the docking connector (not shown) to fasten with the fastening groove 143 after entering the guide groove 115. The slot 113 connects to the guide groove 115 in the left-right direction and the fastening groove 143 connects to the guide groove 115 in the up-down direction. In this application, the direction of the slot 113 connecting to the guide groove 115 is different from the direction of the fastening groove 143 connecting to the guide groove 115, which can avoid weakening the structural strength of the insulating body 11 in the left-right direction and also reduce the difficulty of the manufacturing process.

[0044] 10. The height of the slot 113 along the vertical direction is less than the height of the guide groove 115 and the height of the tongue plate (not shown) is less than the height of the guide part (not shown). This helps prevent misalignment when the electrical connector 1 and the mating connector (not shown) are mated. The center line L1 of the slot 113 along the vertical direction is higher than the center line L2 of the guide groove 115, preventing the mating connector (not shown) from being inserted backwards. This further facilitates the engagement of the locking groove 143 with the locking part (not shown) of the mating connector (not shown). The fact that the height of the slot 113 is less than the height of the guide groove 115 along the vertical direction and the center line L1 of the slot 113 is higher than the center line L2 of the guide groove 115 are both set together and cooperate with each other. This helps the electrical connector 1 and the mating connector (not shown) to be mated accurately and without error, further ensuring stable electrical contact between the two.
