Description

[Technical field]

[0001] The utility model relates to an electric connector, in particular to an electric connector with a double blocking structure between a signal conductive component and an insulating body to prevent retreat. [Background technology]

[0002] There is an electrical connector for the automotive industry, which includes an insulating body and a signal conductive member arranged on the insulating body. Since the signal conductive member is composed of a square terminal to form a cylindrical docking portion and a tail portion inserted into the motherboard of an electronic device, it cannot be embedded with the insulating body, otherwise the molten plastic will easily flow into the cylindrical docking portion. To solve this technical problem, the common method used by those skilled in the art is to set a locking beam on the signal conductive member and fix it to the insulating body by assembly to prevent it from withdrawing backwards. However, with the increasing requirements for vibration detection of automobiles, the retention force of the signal conductive member in the insulating body is obviously insufficient. To solve the problem of insufficient retention force of the signal conductive member in the insulating body, the method adopted in the industry is to add an additional rear plug, which is provided with a tightening cantilever, and the boss on the tightening cantilever is provided to perform interference fit with the inner wall surface of the receiving groove in the insulating body, so as to fix the rear plug to the insulating body and realize the secondary axial positioning of the signal conductive member. However, since the boss on the tightening cantilever is provided to fix the rear plug, and does not directly stop the signal conductive component, the signal component still has the risk of loosening from the rear plug, resulting in a poor secondary stopping effect. In addition, the addition of the rear plug requires a corresponding set of molds for forming the rear plug. When assembling the electrical connector, an additional process of assembling the rear plug to the rear of the insulating body is required, resulting in an increase in material and labor costs. In addition, since the rear plug is assembled with an elastic tightening cantilever, the assembly gap is set too large, resulting in low position accuracy of the signal conductive component and large assembly error. Therefore, the problem faced is how to improve the structure of the existing electrical connector to achieve sufficient holding force to remain in the insulating body and achieve reliability and stability of the signal conductive component while avoiding a substantial increase in the cost and an increase in the number of assembly processes of the electrical connector. This problem needs to be solved urgently.

[0003] Therefore, it is necessary to design an electrical connector to overcome the above problems. [Contents of the utility model]

[0031] like Figure 1 , Figure 4 As shown, an electrical connector 100 is used in the automotive industry. The front end of the electrical connector 100 is plugged into a docking connector (not shown), and the rear end of the electrical connector 100 is installed in a housing mainboard (not shown). It includes an insulating body 1, at least one signal conductive component 2, and at least one power conductive component 3. The power conductive component 3 is embedded in the insulating body 1, and the signal conductive component 2 is assembled in the insulating body 1 from the back to the front.

[0032] like Figure 1-3As shown in Figures 5-8, the insulating body 1 has a mounting portion 11 and a docking cavity 12 extending forward from the mounting portion 11. The mounting portion 11 includes a mounting seat 111 located at the rear and a flange 112 located in front of the mounting seat 111 and extending radially. The mounting seat 111 is inserted into a device housing (not shown), and the flange 112 is fixed to the surface of the device housing. An insulating block 13 is integrally provided in the docking cavity 12. An outer wall extends forward from the mounting seat 111, and the outer wall is arranged around the periphery of the docking cavity 12. A locking protrusion 121 is provided on the upper surface of the outer wall. The docking cavity 12 is for the docking connector to be inserted, and the locking protrusion 121 is locked with the corresponding locking structure of the docking connector. The insulating body 1 is provided with at least one receiving groove 14 along the front-to-back direction. In this embodiment, two receiving grooves 14 are provided to receive the signal conductive member 2. The receiving groove 14 is recessed forward from the rear end of the mounting seat 111 and penetrates the insulating block 13. The two receiving grooves 14 are arranged in the up-down direction, and the up-down direction is perpendicular to the front-to-back direction. Since the upper and lower receiving grooves 14 are symmetrically arranged at 180 degrees along the center point between the two, the receiving groove 14 located at the top is described in detail. The receiving groove 14 has an inner top wall 15, an inner bottom wall 16, and a first inner side wall 17 and a second inner side wall 18 connecting the inner top wall 15 and the inner bottom wall 16. The inner top wall 15, the inner bottom wall 16, the first inner side wall 17 and the second inner side wall 18 are arranged to form the receiving groove 14. The inner bottom wall 16 is a flat surface, and the inner top wall 15, the first inner side wall 17 and the second inner side wall 18 are all non-flat surfaces. A step 171 is protruded from the first inner side wall 17 . The step 171 extends along the front-to-back direction and is in a straight strip shape.A blocking surface 1712 is provided in the receiving groove 14, and an elastic stopper 1713 is integrally extended backward from the rear end opening of the receiving groove 14. Specifically, a notch 1711 is recessed upward from the step 171 of the first inner side wall 17. The notch 1711 is located at the front section of the receiving groove 14 and penetrates the insulating block 13 forward. The left side of the notch 1711 and the lower side of the notch 1711 are both open structures to be connected to the receiving groove 14. The rear wall surface of the notch 1711 forms the blocking surface 1712. The step 171 of an inner side wall 17 extends backward to form the elastic stopper 1713. The elastic stopper 1713 is an elastic hook and includes a cantilever 1713A and a hook 1713B located at the free end of the cantilever 1713A. The hook 1713B and the end of the cantilever 1713A are arranged near the rear end opening of the receiving slot 14. The rear end surface of the hook 1713B is formed with a guide surface so that the signal conductive member 2 can smoothly pass over the hook 1713B at the hook 1713B and continue to be assembled forward. The elastic stopper 1713 is located in the receiving slot 14 and does not protrude backward to the outside of the receiving slot 14. A clearance space 1121 is recessed from the rear end surface of the mounting seat 111 corresponding to the right side of the elastic stopper 1713. Of course, in other embodiments, the elastic stopper 1713 can extend backward to protrude outside the receiving slot 14, which is not limited here. The insulating body 1 has two partitions 1122 extending backward from the rear end, each of which extends backward from the mounting seat 111 and is used to be inserted into the positioning hole of the housing mainboard. The two partitions 1122 extend farther and further backward than the signal conductive member 2 and the power conductive member 3. The ends of the partitions 1122 are provided with chamfered structures, which can guide the partitions 1122 to be smoothly inserted into the positioning holes of the housing mainboard when the partitions 1122 are inserted into the housing mainboard.

[0033] like Figure 3 , 4As shown in FIGS. 6 and 7, in this embodiment, two signal conductive members 2 are provided, and the two signal conductive members 2 are respectively assembled in the two receiving grooves 14 from the rear end opening of the receiving groove 14. Since the signal conductive members 2 assembled in the upper and lower receiving grooves 14 have the same structure, and the two signal conductive members 2 are arranged 180 degrees symmetrically along the center point between the two, that is, the signal conductive member 2 located at the upper side can be symmetrical with the signal conductive member 2 located at the lower side after rotating 180 degrees around the circumference perpendicular to the front-back direction at the center point between the two sides, the signal conductive member 2 located at the upper side is described in detail, and the signal conductive member 2 includes a flat terminal 21 and a square terminal 22. The flat terminal 21 has a plate terminal body 211, and the plate terminal body 211 is arranged horizontally. The plate terminal body 211 includes a central portion 2111 and an offset portion 2112 horizontally offset from the rear end of the central portion 2111 toward a side away from the elastic stop portion 1713 and extending backward. In the example listed this time, the offset portion 2112 is offset from the left side of the rear end of the central portion 2111 and extends backward. A tip portion 212 extends forward from the central portion 2111. The width of the tip portion 212 is smaller than that of the central portion 2111 so as to facilitate better connection and fixation with the square terminal 22. The tip portion 212 coincides with the central axis of the central portion 2111 along the front-to-back direction. A limiting portion 213 is formed by bending and extending from the side of the rear section of the offset portion 2112 close to the elastic stop portion 1713. In the example listed this time, the limiting portion 213 is bent and extended from the right side of the rear section of the offset portion 2112. The limiting portion 213 is exposed at the rear end opening of the receiving groove 14 and is arranged corresponding to the side of the elastic stop portion 1713 away from the clearance space 1121. The limiting portion 213 includes a bending section 2131 connected to the offset portion 2112 and a vertical section 2132 extending from the bending section 2131. The vertical section 2132 is perpendicular to the central portion 2111, and the hook portion 1713B of the elastic stop portion 1713 blocks the rear end surface of the vertical section 2132. An opening is formed between the front end surface of the limiting portion 213 and the rear end surface of the central portion 2111 to be spaced apart.When the signal conductive component 2 is assembled forward to the receiving groove 14, the guide surface facilitates the vertical section 2132 of the limiting portion 213 to pass forward over the hook portion 1713B, and the elastic stopping portion 1713 elastically deforms to the right along the left-right direction to make way for the vertical section 2132 to pass forward over the hook portion 1713B of the elastic stopping portion 1713. At this time, the elastic stopping portion 1713 enters the making way space 1121 to the right to avoid the vertical section 2132 from entering the receiving groove 14 forward, so that the signal conductive component 2 can be smoothly assembled into the receiving groove 14. The elastic stopping portion 1713 returns to the stopping position under the action of its own restoring force to stop the vertical section 2132, and finally the hook portion 1713B hooks the rear edge of the vertical section 2132 to lock and stop it from moving backward. By providing the offset portion 2112, the vertical section 2132 is made closer to the central axis of the central portion 2111 along the front-to-back direction, ensuring that the signal conductive component 2 can be smoothly assembled into the receiving groove 14. The rear side of the limiting portion 213 extends backward to form a signal tail portion 214, and the signal tail portion 214 protrudes from the mounting seat 111. The signal tail portion 214 includes a tapered section 2141 connected to the vertical section 2132 and an insertion section 2142 extending linearly backward from the tapered section 2141. The insertion section 2142 has a plate-like structure for being inserted and fixed in the conductive hole of the case mainboard, and is clamped by the spring clip in the conductive hole of the case mainboard, thereby establishing a stable electrical connection between the signal conductive component 2 and the case mainboard. The thickness of the tapered section 2141 increases from the limiting portion 213 toward the The signal tail portion 214 is gradually reduced, so that the thickness of the insertion section 2142 is smaller than the thickness of the limiting portion 213, which facilitates the insertion of the insertion section 2142 into the conductive hole of the case mainboard, and the clamping force of the spring clip in the conductive hole of the case mainboard on the signal tail portion 214 is smaller than the holding force of the insulating body 1 on the signal conductive component 2, thereby avoiding the situation where only the insulating body 1 is pulled out and the signal conductive component 2 is left on the case mainboard when the electrical connector 100 needs to be pulled out.

[0034] like Figure 2 , 4As shown in FIGS. 6 and 7, the square terminal 22 includes a cylindrical signal docking portion 221 and a connecting portion 222 fixedly connected to the front end of the flat terminal 21. The signal docking portion 221 and the connecting portion 222 are both received in the receiving groove 14, and the signal docking portion 221 is exposed at the front end of the insulating block 13. In this embodiment, the signal docking portion 221 includes a plurality of elastic contact arms 2211 integrally connected to the connecting portion 222 and an outer sleeve 2212 sleeved outside the elastic contact arms 2211. The plurality of elastic contact arms 2211 are surrounded to form a cylindrical structure. Of course, in other embodiments, the signal docking portion 221 may be an integral connector in which the outer sleeve 2212, the elastic contact arms 2211, and the connecting portion 222 are not limited here. A stop portion 2212A is provided on one side of the signal docking portion 221. In the present embodiment, the stop portion 2212A is a beam-like structure extending in the front-to-back direction. The stop portion 2212A is formed on the top surface of the outer sleeve 2212. The front end of the stop portion 2212A is integrally connected with the top surface of the outer sleeve 2212. The stop portion 2212A is formed to extend obliquely upward and backward from one side of the signal docking portion 221. The stop portion 2212A forms an elastic structure (of course, in other embodiments, the stop portion 2212A can be set as a protrusion with a stopping function, thereby forming a stop with the blocking surface 1712 at the front end of the spear-shaped object extending in the receiving groove 14, which is not limited here). When the signal conductive component 2 is assembled forward to the receiving groove 14, the stop portion 2212A can be elastically deformed downward in the up-down direction to pass forward over the blocking surface 1712, and the end of the stop portion 2212A is upwardly snapped into the notch 1711 corresponding to the stop portion 2212A under the action of the elastic restoring force, and the end of the stop portion 2212A is stopped by the blocking surface 1712 to prevent it from moving backward. Since the square terminal 22 needs to be stamped and bent multiple times to form a box shape, in order to facilitate multiple stamping and bending, the thickness of the selected plate will not be very thick, while the flat terminal 21 does not need to consider the factor of multiple stamping and bending to form a box shape, and the thickness of the selected plate is not affected. Therefore, in this embodiment, the thickness of the vertical section 2132 is greater than the thickness of the stop portion 2212A, so that the vertical section 2132 has better strength, and when the hook portion 1713B locks and stops the vertical section 2132, the vertical section 2132 can withstand a greater force of moving backward and the vertical section 2132 is not easy to deform.The blocking surface 1712 blocks the end of the stop portion 2212A, forming a first blocking structure to block the signal conductive member 2 from moving backwards. The hook portion 1713B hooks the rear edge of the vertical section 2132, forming a second blocking structure to block the signal conductive member 2 from moving backwards. The second blocking structure compensates for the lack of holding force of the first blocking structure on the signal conductive member 2. The first blocking structure and the second blocking structure jointly prevent the signal conductive member 2 from moving backwards, ensuring that there is sufficient holding force between the signal conductive member 2 and the insulating body 1, so as to prevent the stop portion 2212A on the signal conductive member 2 from being deformed and damaged due to the lack of holding force of the first blocking structure. The connecting portion 222 has a bottom wall 2221 and a plurality of riveting claws 2222 extending from the left and right sides of the bottom wall 2221. The tip portion 212 is placed on the bottom wall 2221 and fixed by riveting with the plurality of riveting claws 2222, thereby connecting and fixing the square terminal 22 to the flat terminal 21.

[0035] like Figure 1 , 4As shown, in this embodiment, two power conductive members 3 are provided, and the two power conductive members 3 are arranged in the left-right direction and embedded in the insulating body 1, and the two signal conductive members 2 are located between the two power conductive members 3. The power conductive member 3 is a plate-shaped structure, and each of the power conductive members 3 includes a power docking portion 31, a power fixing portion 32 and a power tail portion 33 connected in sequence in the left-right direction. The power docking portion 31 is accommodated in the docking cavity 12 and is spaced apart from the insulating block 13. The cross-sectional area of ​​the power tail portion 33 is larger than the cross-sectional area of ​​the signal tail portion 214, and the power tail portion 33 protrudes out of the mounting seat 111 to be inserted and fixed to the conductive hole of the housing mainboard. The power fixing portion 32 is generally in a "Z" shape, the front section of the power fixing portion 32 is on the same straight line as the power docking portion 31, the rear section of the power fixing portion 32 is on the same straight line as the power tail portion 33, the front section of the power fixing portion 32 is bent and connected with the rear section of the power fixing portion 32, and the rear section of the power fixing portion 32 is closer to the outside in the left and right direction to increase the creepage distance and electrical clearance between the power tail portion 33 of one power conductive member 3 and the power tail portion 33 of another power conductive member 3. The power fixing portion 32 is respectively provided with a protrusion 321 on both sides along the up and down direction, and the protrusion 321 is in a square structure. The protrusion 321 is embedded in the mounting portion 11 together with the power fixing portion 32, and the front edge and rear edge of each protrusion 321 are blocked by the insulating material of the insulating body 1 to limit the displacement of the power conductive member 3 in the front and back directions. Since the power conductive member 3 in this embodiment is used to transmit a relatively high voltage, the thickness of the power tail 33 is designed to be larger than the thickness of the signal tail 214. Each of the partitions 1122 is located between the power conductive member 3 and the adjacent signal conductive member 2, separating the signal conductive member 2 from the power conductive member 3, increasing the creepage distance and electrical clearance, thereby reducing the interference of the power conductive member 3 transmitting high voltage on the signal conductive member 2.

[0036] In summary, the electrical connector 100 of the present invention has the following beneficial effects:

[0037] 1. The receiving groove 14 is provided with the blocking surface 1712, and the elastic stopping portion 1713 is integrally extended backward at the rear end opening of the receiving groove 14. The stopping portion 2212A is stopped by the blocking surface 1712 to move backward, forming a first blocking structure to stop the signal conductive member 2 from moving backward. The limiting portion 213 is stopped by the elastic stopping portion 1713 to move backward, forming a second blocking structure to stop the signal conductive member 2 from moving backward. The second blocking structure makes up for the insufficient holding force of the first blocking structure on the signal conductive member 2. The first blocking structure and the second blocking structure jointly prevent the signal conductive member 2 from moving backward, ensuring that there is sufficient holding force between the signal conductive member 2 and the insulating body 1, thereby preventing the stopping portion 2212 on the signal conductive member 2 from being blocked. A is deformed and damaged due to insufficient holding force of the first blocking structure. Compared with the prior art, since the elastic stopping portion 1713, the blocking surface 1712 and the insulating body 1 are formed as an integral part, while the signal conductive component 2 is reliably and stably held on the insulating body 1, large assembly errors are avoided, the position accuracy of the signal conductive component 2 is improved, the assembly process is simplified, and multiple independent plugs are avoided, thereby saving material costs and labor costs. In addition, the sufficient holding force of the signal conductive component 2 can not only detect the current change of the electrical connector 100 in time to facilitate safe power off, but also facilitate the pull-out of the signal conductive component 2 together with the insulating body 1 during maintenance and disassembly, thereby avoiding only pulling out the insulating body 1 and leaving the signal conductive component 2 on the main board.

[0038] 2. The clearance space 1121 is recessed from the rear end surface of the mounting seat 111 to the right side of the elastic stop portion 1713. The clearance space 1121 is arranged corresponding to the side of the elastic stop portion 1713 away from the limiting portion 213, so that the signal conductive component 2 is assembled forward to the receiving groove 14. The elastic stop portion 1713 is elastically deformed to the right along the left-right direction and enters the clearance space 1121 to the right to avoid the vertical section 2132, so that the vertical section 2132 passes forward over the hook portion 1713B of the elastic stop portion 1713, and the signal conductive component 2 can be smoothly assembled into the receiving groove 14.

[0039] 3. The notch 1711 is recessed upward from the step 171 of the first inner wall 17, and the rear wall surface of the notch 1711 forms the blocking surface 1712. The step 171 of the first inner wall 17 extends backward to form the elastic stopping portion 1713. The blocking surface 1712 blocks the end of the stop portion 2212A, and the elastic stopping portion 1713 blocks the limiting portion 213. Compared with the prior art, since the elastic stopping portion 1713, the blocking surface 1712 and the insulating body 1 are formed as an integrated piece, while the signal conductive component 2 is reliably and stably maintained on the insulating body 1, large assembly errors are avoided, the position accuracy of the signal conductive component 2 is improved, the assembly process is simplified, and it is avoided that molds are opened due to the need to set up multiple independent components to form a second barrier, thereby saving material costs and labor costs.

[0040] 4. The stop portion 2212A can be elastically deformed downward along the up-down direction to pass forward over the blocking surface 1712. Under the action of the elastic restoring force, the end of the stop portion 2212A is upwardly snapped into the notch 1711 corresponding to the stop portion 2212A and is stopped by the blocking surface 1712. The elastic stopping portion 1713 is elastically deformed rightward along the left-right direction to make way for the vertical section 2132 to pass forward over the hook 1713B of the elastic stopping portion 1713. The elastic stopping portion 1713 returns to the stopping position under the action of its own restoring force to stop the vertical section 2132. The directions of elastic deformation of the stop portion 2212A and the elastic stopping portion 1713 are two directions perpendicular to each other. Even in a shaking state, the signal conductive component 2 can always be stably blocked.

[0041] 5. The board terminal body 211 includes the central portion 2111 and the offset portion 2112 offset from the left side of the rear end of the central portion 2111 and extending toward the rear. The limiting portion 213 is bent and extended from the right side of the rear section of the offset portion 2112. The limiting portion 213 includes the bending section 2131 connected to the offset portion 2112 and the vertical section 2132 extending from the bending section 2131. The vertical section 2132 is perpendicular to the central portion 2111. The hook portion 1713B of the elastic stopping portion 1713 stops the rear end surface of the vertical section 2132. By setting the offset portion 2112, the vertical section 2132 is closer to the central axis of the central portion 2111 along the front-to-back direction, ensuring that the signal conductive component 2 can be smoothly assembled into the receiving groove 14 and forming a second blocking structure for the signal conductive component 2 to stop the signal conductive component 2 from moving backward.

[0042] 6. The insulating body 1 has two partitions 1122 extending backward, and the two partitions 1122 extend farther and further backward than the signal conductive member 2 and the power conductive member 3. Each partition 1122 is located between the power conductive member 3 and the adjacent signal conductive member 2, separating the signal conductive member 2 from the power conductive member 3, increasing the creepage distance and electrical clearance, thereby reducing the interference of the power conductive member 3 transmitting high voltage on the signal conductive member 2.

[0043] The above detailed description is only an explanation of the preferred embodiment of the utility model, and does not limit the patent scope of the utility model. Therefore, all equivalent technical changes made by using the description and illustrations of this creation are included in the patent scope of this creation.
