Description

Technical Field

[0001] The present application relates to the field of automotive parts, and particularly to an integrated injection molded new type of automotive PCB board docking connector. Background Art

[0002] A connector is also called a coupler, generally referring to an electrical connector. The male end and female end of the connector can transmit information or current after contact. The PCB docking connector of an electric vehicle is mainly used for signal acquisition of the main board of the electric vehicle and signal acquisition of the battery pack of the electric vehicle.

[0003] In the prior art, the pin terminals of the vertical board-end connector are separately arranged from the plastic structure. During the process of assembling the connector pin terminals to the plastic structure, the flatness and ortho-position of each pin terminal need to be ensured, resulting in high assembly difficulty, high loss of the pin terminals, and easy deviation and difficult control of the ortho-position of the pin terminals. Especially for the case where the number of pins is greater than 12, the pins are often arranged separately. During the assembly process of the separately arranged pins, it is particularly difficult to control the flatness and ortho-position of the pin terminals. Summary of the Invention

[0004] In order to improve the flatness and ortho-position of the pins of the PCB docking connector, the present application provides an integrated injection molded new type of automotive PCB board docking connector.

[0005] The integrated injection molded new type of automotive PCB board docking connector provided by the present application adopts the following technical solutions: The integrated injection molded new type of automotive PCB board docking connector includes two rows of pin leads, a primary injection molded connection body, and a secondary injection molded housing. The two rows of pin leads are fixed to the primary injection molded connection body by in-mold embedding injection. The primary injection molded connection body is fixed to one end of the secondary injection molded housing by in-mold embedding injection. An insertion interface is provided at the end of the secondary injection molded housing away from the primary injection molded connection body. One end of the pin lead extends into the inner side of the secondary injection molded housing, and the other end of the pin lead is provided with a bent welding section. The bent welding sections of the two rows of pin leads are distributed in the same plane and are alternately arranged along a straight line direction. Fixed connection pieces are respectively provided on both sides of the secondary injection molded housing, and the fixed connection pieces are used for welding and fixing to the PCB board. The surface of the fixed connection piece for contacting the PCB board is set as an abutting surface, and the abutting surface is parallel to the orientation of the insertion interface.

[0006] By adopting the above technical solution, during the manufacturing process of the docking connector, the pin pins are processed by stamping. During the processing of the pin pins, one ends of the respective pin pins are connected in series by a strip. After the pin pins are processed, two columns of pin pins that have not had the strip removed are combined, and then a primary injection molded connector body is injection molded by an embedded injection molding method, so that the primary injection molded connector body and the two columns of pin pins are integrally connected; then a secondary injection molded housing is injection molded on the primary injection molded connector body, so that the secondary injection molded housing, the primary injection molded connector body and the two columns of pin pins are connected into an integral structure, and then the strip connecting the two columns of pin pins is removed. The pin pins of the docking connector are arranged in two columns to meet the layout requirements of a relatively large number of pins. After the connecting strip of the two columns of pin pins is fixed by means of embedded injection molding and then removed, it is beneficial to keep the relative positions of the two columns of pin pins relatively constant, thereby facilitating the control of the flatness and ortho-position of each pin pin.

[0007] Optionally, fixing connection pieces are respectively arranged on two sides of the secondary injection molded housing, clamping grooves for inserting the fixing connection pieces are respectively arranged on two sides of the secondary injection molded housing, a widened limiting portion is arranged on one side of the fixing connection piece, the widened limiting portion can prevent the fixing connection piece from being disengaged from the clamping groove in one direction, a bent welding portion is arranged on the side of the fixing connection piece away from the widened limiting portion, the bent welding portion is used for welding with a PCB board, and the surface of the bent welding portion for contacting the PCB board is set as an abutting surface, and the abutting surface is parallel to the orientation of the insertion interface.

[0008] By adopting the above technical solution, the docking connector is connected to the PCB board through two fixing connection pieces, and the widened limiting portion of the fixing connection piece can prevent the secondary injection molded housing from moving away from the PCB board, so that the docking connector is fixed on the PCB board.

[0009] Optionally, the fixing connection piece is provided with a stamping recessed area, and the stamping recessed area abuts against the inner wall of the clamping groove.

[0010] By adopting the above technical solution, the fixing connection piece is inserted into the clamping groove, and the stamping recessed area of the fixing connection piece abuts against the inner wall of the clamping groove, causing local elastic deformation of both the fixing connection piece and the inner wall of the clamping groove simultaneously, making the fit between the fixing connection piece and the inner wall of the clamping groove tighter and more stable.

[0011] Optionally, it further includes a limiting component, the limiting component includes a limiting stop bar and connecting pieces located at both ends of the limiting stop bar, the two connecting pieces are respectively connected corresponding to the two fixing connection pieces, the primary injection molded connector body is provided with a limiting groove for avoiding the limiting stop bar, and the limiting stop bar can prevent the primary injection molded connector body from approaching the fixing connection piece.

[0012] By adopting the above technical solution, when the docking connector installed on the PCB board is used for plugging into the board, the overall structure composed of the secondary injection-molded housing, the primary injection-molded connector body, and the pin leads will be driven by the insertion and extraction force. As a result, the connection between the pin leads and the PCB board will be driven by the insertion and extraction force. By setting the limiting component connected to the fixed connecting piece and using the limiting component to limit the primary injection-molded connector body, the driving effect of the insertion and extraction force on the connection between the pin leads and the PCB board can be reduced.

[0013] Optionally, the connecting piece is provided with a through hole for the limiting rod to pass through. External threads are respectively provided at both ends of the limiting rod, and nuts are connected to both ends of the limiting rod through the external threads. The nuts are located on the side of the connecting piece away from the primary injection-molded connector body, and the two nuts jointly clamp the primary injection-molded connector body.

[0014] By adopting the above technical solution, the two nuts jointly lock the primary injection-molded connector body, which can form a relatively stable connection relationship between the limiting component and the primary injection-molded connector body, so that the limiting component can form a better limiting effect on the primary injection-molded connector body. On the other hand, when the two nuts are locked simultaneously, a small elastic tensile deformation occurs in the part of the limiting rod located between the two nuts, making it difficult for the limiting rod to bend and deform under the action of the insertion and extraction force, which is beneficial to the full play of the limiting effect of the limiting rod on the primary injection-molded connector body.

[0015] Optionally, the pin lead is provided with a bent side piece, the bent side piece is buried in the primary injection-molded connector body, and an insulating rod is commonly connected to each bent side piece. The bent side piece is provided with a jack for the insulating rod to pass through.

[0016] By adopting the above technical solution, the bent side pieces of the two rows of pin leads are connected in series through the insulating rod, which is beneficial to keeping the distance between the two rows of pin leads stable, thereby reducing the change of the two rows of pin leads during the injection molding process of the primary injection-molded connector body, and is beneficial to ensuring the position accuracy of the pin leads.

[0017] Optionally, one end of the insulating rod is provided with a bent limiting part, and the other end of the insulating rod is provided with a flattened limiting part.

[0018] By adopting the above technical solution, the bent limiting part and the flattened limiting part can prevent the two rows of pin leads from coming out of the insulating rod, making the relative position between the insulating rod and the two rows of pin leads relatively stable.

[0019] Optionally, a limiting ring is sleeved on the insulating rod. The limiting ring is an insulating part and is located between two adjacent bent side pieces of the two pin pins. A micro spring is sleeved on the insulating rod. The micro spring is in a pre-compressed state and can force the two bent side pieces adjacent to the limiting ring to jointly clamp the limiting ring.

[0020] By adopting the above technical solution, before the two rows of pin pins are connected by the one-time injection molding connector, the pitch between the pin pins in the same row is maintained by the tape, while the pitch between the two rows of pin pins is maintained by the separation of the limiting ring and the elastic force of the micro spring, so that the position accuracy of each pin pin is better controlled.

[0021] Optionally, there are two insulating rods. The two insulating rods are parallel to each other. There are two jacks on each bent side piece, and the bent limiting parts of the two insulating rods are integrated.

[0022] By adopting the above technical solution, the two insulating rods are integrated. The two insulating rods pass through the bent side pieces of each pin pin at the same time, making it difficult for the fork pin to rotate around one of the insulating rods, which is beneficial to further stabilizing the position of the pin pin.

[0023] Optionally, the insulating rod includes a metal core rod and an insulating rubber covering the metal core rod.

[0024] By adopting the above technical solution, the metal core rod of the insulating rod gives the insulating rod higher strength, and the insulating rubber of the insulating rod insulates the insulating rod from the pin pins.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. During the manufacturing of the docking connector, after the connecting belt of the two rows of pin pins is fixed by the means of embedded injection molding and then cut off, it is beneficial to keep the relative positions of the two rows of pin pins relatively constant, which is beneficial to controlling the flatness and ortho-position of each pin pin.

[0026] 2. The docking connector is connected to the PCB board through two fixed connecting pieces. The widened limiting part of the fixed connecting piece can prevent the secondary injection molding shell from moving away from the PCB board, so that the docking connector is fixed on the PCB board.

[0027] 3. By setting a limiting component connected to the fixed connecting piece and using the limiting component to limit the one-time injection molding connector, the driving effect of the insertion and extraction force on the connection between the pin pin and the PCB board can be reduced.

[0038] The following further Figures 1-9 describes the present application in detail with reference to the

[0039] Embodiment 1 The embodiment of the present application discloses a novel one-piece injection-molded automotive PCB board docking connector. Refer toFigure 1 and Figure 2 An integrated injection-molded docking connector for a new type of automotive PCB board, comprising two rows of pin terminals 1, a primary injection-molded connector body 2, and a secondary injection-molded housing 3. The two rows of pin terminals 1 are fixed to the primary injection-molded connector body 2 by insert molding. The number of pin terminals 1 in each row is twelve. The primary injection-molded connector body 2 is fixed to one end of the secondary injection-molded housing 3 by insert molding. An insertion port 31 is provided at one end of the secondary injection-molded housing 3 away from the primary injection-molded connector body 2.

[0040] Referring to Figures 2-4 , one of the two rows of pin terminals 1 is a long pin terminal 101, and the other is a short pin terminal 102; One end of the pin terminal 1 extends into the inner side of the secondary injection-molded housing 3, and the other end of the pin terminal 1 is provided with a bent welding section 11. The bent welding sections 11 of the two rows of pin terminals 1 are distributed in the same plane and are alternately arranged along a straight line direction; That is: the bent welding sections 11 of the long pin terminal 101 and the short pin terminal 102 are bent and formed at the same corner.

[0041] Referring to Figure 2 , fixing connection pieces 4 are respectively provided on both sides of the secondary injection-molded housing 3. The fixing connection pieces 4 are used for welding and fixing with the PCB board; Card slots 32 for inserting the fixing connection pieces 4 are respectively provided on both sides of the secondary injection-molded housing 3. The card slots 32 protrude outward on the outer side surface of the secondary injection-molded housing 3. A widened limiting portion 41 is provided on one side of the fixing connection piece 4. Concave corners are respectively formed between the widened limiting portion 41 and both sides of the main body portion of the fixing connection piece 4. The widened limiting portion 41 can prevent the fixing connection piece 4 from being disengaged from the card slot 32 in one direction. A bent welding portion 42 is provided on the side of the fixing connection piece 4 away from the widened limiting portion 41. The bent welding portion 42 is used for welding with the PCB board. The surface of the bent welding portion 42 for contacting the PCB board is set as an abutting surface 421. The abutting surface 421 is parallel to the orientation of the insertion port 31. The abutting surface 421 is parallel to the distribution plane of the bent welding sections 11.

[0042] The bent welding portion 42 is a structure formed by bending the fixing connection piece 4 after it is inserted into the card slot 32. In order to make the bent welding portion 42 easier to bend and process, a material-reducing opening 45 is provided at the corner portion of the bent welding portion 42. The material-reducing opening 45 can weaken the strength of the fixing connection piece 4, so as to facilitate bending processing.

[0043] Referring to Figure 2 , the fixing connection piece 4 is provided with a stamping depression area 43. The stamping depression area 43 abuts against the inner wall of the card slot 32. When the fixing connection piece 4 is inserted into the card slot 32, local elastic deformation occurs between the stamping depression area 43 of the fixing connection piece 4 and the inner wall of the card slot 32, making the insertion state between the fixing connection piece 4 and the card slot 32 relatively stable and reliable.

[0044] The assembly method of the above-mentioned integrated injection-molded new automotive PCB board docking connector includes the following steps: Step 1: Stamping the pin feet 1. Every twelve pin feet 1 form a column, and a strip of material is reserved on the twelve pin feet 1 in the same column. The strip of material is the material that connects the pin feet 1 in series during the stamping process. Two types of pin feet 1 need to be prepared for each docking connector, namely: long pin feet 101 and short pin feet 102. The length of the long pin feet 101 is greater than that of the short pin feet 102. Step 2: After arranging two columns of pin feet 1 with strips of material side by side, injection-mold the primary injection-molded connector body 2 once, so that the primary injection-molded connector body 2 is connected to the two columns of pin feet 1 to form a whole. Step 3: Injection-mold the secondary injection-molded housing 3 in the way of embedded injection molding, so that one end of the secondary injection-molded housing 3 is connected to the primary injection-molded connector body 2 to form a whole. Step 4: Cut off the strips of material on the two columns of pin feet 1, so that the bent welding section 11 of the pin feet 1 is separated from the strip of material. Step 5: Insert two fixing connection pieces 4 into both sides of the secondary injection-molded housing 3 respectively, and then bend one side of the fixing connection piece 4 to form a bent welding part 42. The implementation principle of the integrated injection-molded new automotive PCB board docking connector in the embodiment of the present application is as follows: During the manufacturing process of the docking connector, the pin feet 1 are processed by stamping. During the processing of the pin feet 1, one end of each pin feet 1 is connected in series through a strip of material. After the pin feet 1 are processed, the two columns of pin feet 1 that have not had the strips of material cut off are combined. Then, the primary injection-molded connector body 2 is injection-molded in the way of embedded injection molding, so that the primary injection-molded connector body 2 is connected to the two columns of pin feet 1 to form a whole. Then, the secondary injection-molded housing 3 is injection-molded on the primary injection-molded connector body 2, so that the secondary injection-molded housing 3, the primary injection-molded connector body 2 and the two columns of pin feet 1 are connected to form an integral structure. Subsequently, the strip of material connecting the two columns of pin feet 1 is cut off. After the connecting strip of the two columns of pin feet 1 is fixed by means of embedded injection molding and then cut off, it is beneficial to keep the relative positions of the two columns of pin feet 1 relatively constant, thereby facilitating the control of the flatness and ortho-position of each pin feet 1.

[0045] Embodiment 2 Refer to Figures 5-7, The difference between this embodiment and Embodiment 1 is that the docking connector further includes a limiting component 5. The limiting component 5 includes a limiting stop bar 51 and connecting pieces 52 located at both ends of the limiting stop bar 51. Both connecting pieces 52 are metal parts. The two connecting pieces 52 correspond to the two fixed connection pieces 4 respectively. The connecting piece 52 and the corresponding fixed connection piece 4 are connected by a fastener 53. The fastener 53 includes a countersunk head screw 531 and a nut 532. The head of the countersunk head screw 531 is located between the fixed connection piece 4 and the inner wall of the clamping groove 32. The fixed connection piece 4 is provided with a tapered hole 44 adapted to the head of the countersunk head screw 531. The nut 532 is threadedly connected to the screw 531. The nut 532 is located on the side of the connecting piece 52 away from the fixed connection piece 4. The nut 532 and the head of the screw 531 lock the fixed connection piece 4 and the connecting piece 52 at the same time.

[0046] One end of the countersunk head screw 531 away from the head is provided with a screwdriver slot 5311. During the process of locking the nut 532, a screwdriver is used to limit the countersunk head screw 531 to facilitate tightening the nut 532.

[0047] Refer to Figure 5 and Figure 6 , The one-time injection molded connector body 2 is provided with a limiting groove 21 for avoiding the limiting stop bar 51. The limiting stop bar 51 is provided with two parallel longitudinal sections 511. The two longitudinal sections 511 respectively abut against the two inner side walls of the limiting groove 21. The connecting piece 52 is provided with a through hole 521 for the limiting stop bar 51 to pass through. External threads 512 are respectively provided at both ends of the limiting stop bar 51. Nuts 54 are connected to both ends of the limiting stop bar 51 through the external threads 512. The nuts 54 are located on the side of the connecting piece 52 away from the one-time injection molded connector body 2. The two nuts 54 jointly clamp the one-time injection molded connector body 2. A spring washer 55 is provided between the nut 54 and the connecting piece 52.

[0048] When the docking connector installed on the PCB board is used for plugging the board, the overall structure composed of the secondary injection molded housing 3, the one-time injection molded connector body 2 and the pin leads 1 will be driven by the plugging and unplugging force, so that the connection between the pin leads 1 and the PCB board will be driven by the plugging and unplugging force. In this embodiment, the limiting stop bar 51 of the limiting component 5 is stuck in the limiting groove 21 of the secondary injection molded connector body, so that the limiting stop bar 51 can prevent the one-time injection molded connector body 2 from approaching the fixed connection piece 4. Thus, the limiting component 5 can limit the one-time injection molded connector body 2 to reduce the driving effect of the plugging and unplugging force on the connection between the pin leads 1 and the PCB board.

[0049] Refer to Figure 8, two elastic members 7 are respectively provided on both sides of the fixed connection piece 4, and the two elastic members 7 are respectively located in two concave corner regions between the widened limiting portion 41 and the main body portion of the fixed connection piece 4; the elastic member 7 is in a strip structure, including a corrugated section 71 and a limiting section 72, the length direction of the corrugated section 71 is perpendicular to the limiting portion, the corrugated section 71 is located between the widened limiting portion 41 and the end of the clamping groove 32, and the limiting section 72 is located between the main body portion of the fixed connection piece 4 and the inner side wall of the clamping groove 32. When the docking connector is in the installed state, the widened limiting portion 41 and the end of the clamping groove 32 can force the corrugated section 71 to deform, and the elastic deformation force of the corrugated section 71 can improve the stability of the installed state of the fixed connection piece 4.

[0050] Embodiment 3 Refer to Figure 9 , the difference between this embodiment and Embodiment 1 is that the pin lead 1 is provided with a bent side piece 12, and the bent side piece 12 is injection-molded and buried inside the primary injection-molded connector 2. Two insulating rods 6 are commonly connected in series among the bent side pieces 12. The two insulating rods 6 are parallel to each other. The insulating rod 6 includes a metal core rod and an insulating rubber covering the metal core rod. Each bent side piece 12 is provided with two insertion holes 121 for the insulating rod 6 to pass through.

[0051] One end of the insulating rod 6 is provided with a bent limiting portion 61, and the bent limiting portions 61 of the two insulating rods 6 are integrally connected, so that the two insulating rods 6 are combined into a U-shaped rod. One end of the insulating rod 6 away from the bent limiting portion 61 is provided with a flattened limiting portion 62.

[0052] The insulating rod 6 is sleeved with a limiting ring 63. The thickness of the limiting ring 63 is equal to the arrangement pitch of each row of pin leads 1. The limiting ring 63 is an insulating part. The limiting ring 63 is located between two adjacent bent side pieces 12 of the two pin leads 1; the insulating rod 6 is sleeved with a micro spring 64. The micro spring 64 is in a pre-compressed state. The micro spring 64 can force the two adjacent bent side pieces 12 near the limiting ring 63 to jointly clamp the limiting ring 63. The micro spring 64 is arranged at any one end of the insulating rod 6. In this embodiment, the micro spring 64 is arranged at the end of the insulating rod 6 where the flattened limiting portion 62 is located.

[0053] The bent side pieces 12 of the two rows of pin leads 1 are connected in series through the insulating rod 6, which is beneficial to keeping the distance between the two rows of pin leads 1 stable, thereby reducing the change of the two rows of pin leads 1 during the injection molding of the primary injection-molded connector 2, and is beneficial to ensuring the position accuracy of the pin leads 1.

[0054] The above are all the preferred embodiments of this application. The protection scope of this application is not limited hereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
