Description

Technical Field

[0001] The invention relates to the technical field of electric connector manufacturing, and in particular to a flexible flat cable extension adapter plate. Background Art

[0002] The flexible cable extension adapter plate is used to connect two relatively flexible cables (such as FPC cables and FFC cables) and acts as a transitional connection bridge.

[0003] like Figure 1 As shown in , the existing soft cable extension adapter board on the market is mainly composed of several parts such as a PCB board, a first bridge part and a second bridge part. Among them, the first bridge part and the second bridge part are both fixed to the PCB board by soldering, and are placed opposite to each other, so as to respectively adapt the first row of cables and the second row of cables one by one. Taking the POS machine application as an example, the PCB board is first fixed to the POS machine motherboard by soldering. When the first row of cables is put into place relative to the first bridge part, the flip piece on the first bridge part is pulled so that its terminal can reliably touch the first row of cables; when the second row of cables is put into place relative to the second bridge part, the flip piece on the second bridge part is also pulled so that its terminal can reliably touch the second row of cables, that is, the conduction between the first row of cables and the second row of cables is achieved. However, this type of flexible cable extension adapter has the following problems in practical applications: when the flexible cable extension adapter is damaged or its model and specification need to be changed, the first cable and the second cable need to be removed from the first bridge portion and the second bridge portion respectively, and then the flexible cable extension adapter needs to be removed from the main board as a whole. Since the PCB board is fixed to the main board by soldering, it is very inconvenient to disassemble the flexible cable extension adapter, and the main board or surrounding accessories are easily damaged during the removal process. In addition, when the space or spacing between the copper traces of the PCB board is small, or when floating conductive objects invade the inside of the POS machine, short circuits can occur, which in turn leads to the interruption of the signal transmission process between the first cable and the second cable. Therefore, it is urgent for technical personnel to solve the above problems. Summary of the invention

[0004] Therefore, in view of the above-mentioned existing problems and defects, the designers of the present invention collected relevant information, conducted multiple evaluations and considerations, and continued to experiment and modify the flexible cable extension adapter after many years of R&D experience in this industry, which ultimately led to the emergence of this flexible cable extension adapter.

[0005] In order to solve the above technical problems, the present invention relates to a flexible flat cable extension adapter plate, which is used to achieve the transition connection between the left-mounted flat cable and the right-mounted flat cable. The flexible flat cable extension adapter plate includes an insulating plastic body, a terminal unit, a left-mounted flip piece and a right-mounted flip piece. The terminal unit is composed of a plurality of terminals inserted in the insulating plastic body and arranged in a linear array along the front-to-back direction. From left to right, the terminals are sequentially connected by a left-mounted plug-in top contact section, a middle fixed section and a right-mounted plug-in top contact section. An intermediate plug-in groove for inserting the middle fixed section and for limiting the position of the middle fixed section is provided on the insulating plastic body. The left-mounted plug-in top contact section and the right-mounted plug-in top contact section are both formed by the reverse extension of the middle fixed section, so as to contact and conduct the left-mounted flat cable and the right-mounted flat cable respectively. The left-mounted flip piece can be freely swung and hinged on the insulating plastic body, and crosses the left-mounted plug-in top contact section. When the left flipping piece is turned, the left mating top contact segment undergoes elastic deformation to achieve the clamping / relaxing operation of the left flat cable. The right flipping piece is freely swingably hinged on the insulating plastic body and crosses the right mating top contact segment. When the right flipping piece is turned, the right mating top contact segment undergoes elastic deformation to achieve the clamping / relaxing operation of the right flat cable.

[0006] As a further improvement of the technical solution of the present invention, the left-mounted plug-in top contact section includes a first top contact arm and a second top contact arm. The first top contact arm is formed by continuing to extend to the left from the left side wall of the middle fixed section and is embedded in the insulating plastic body. The second top contact arm is formed by continuing to extend downward from the lower side wall of the first top contact arm and then bending to the left. The right-mounted plug-in top contact section includes a third top contact arm and a fourth top contact arm. The third top contact arm is formed by continuing to extend to the right from the right side wall of the middle fixed section and is embedded in the insulating plastic body. The fourth top contact arm is formed by continuing to extend downward from the lower side wall of the third top contact arm and then bending to the right.

[0007] As a further improvement of the technical solution of the present invention, the flexible cable extension adapter plate also includes a front auxiliary reinforcement member and a rear auxiliary reinforcement member. The front auxiliary reinforcement member and the rear auxiliary reinforcement member are oriented along the left and right directions and are embedded in the insulating plastic body. The insulating plastic body is provided with a front plug-in slot and a rear plug-in slot for inserting the front auxiliary reinforcement member and the rear auxiliary reinforcement member. The front auxiliary reinforcement member is provided with a first front limit slot and a second front limit slot. The rear auxiliary reinforcement member is provided with a first rear limit slot and a second rear limit slot. When the front auxiliary reinforcement member and the rear auxiliary reinforcement member are plugged in with respect to the insulating plastic body, the first front limit slot and the first rear limit slot are opposite to each other and are partially exposed to the outside of the insulating plastic body, and cooperate to limit the position of the left-placed flip member. The second front limit slot and the second rear limit slot are opposite to each other and are partially exposed to the outside of the insulating plastic body, and cooperate to limit the position of the right-placed flip member.

[0008] As a further improvement of the technical solution of the present invention, the flexible flat cable extension adapter plate also includes a locking piece which is inserted into the insulating plastic body and supports each wiring terminal horizontally at the same time.

[0009] As a further improvement of the technical solution of the present invention, the locking member is connected in sequence by a front clamping arm unit, a middle horizontal supporting section and a rear clamping arm unit. The front clamping arm unit includes a first front clamping arm and a second front clamping arm arranged opposite to each other along the left and right directions. The rear clamping arm unit includes a first rear clamping arm and a second rear clamping arm arranged opposite to each other along the left and right directions. The first front clamping arm, the second front clamping arm, the first rear clamping arm and the second rear clamping arm are all formed by continuing to extend upward from the upper plane of the middle horizontal supporting section. The first front clamping groove, the second front clamping groove, the first rear clamping groove and the second rear clamping groove are extended upward from the bottom wall of the insulating plastic body, and are respectively provided for the first front clamping arm, the second front clamping arm, the first rear clamping arm and the second rear clamping arm to be placed. The bottom wall of the insulating plastic body extends upward to provide a receiving groove for the middle horizontal supporting section to be placed.

[0010] As a further improvement of the technical solution of the present invention, corresponding to the accommodating groove, a front secondary locking extension section and a rear secondary locking extension section are formed on the front auxiliary reinforcement and the rear auxiliary reinforcement, respectively. When the locking member is inserted into the insulating plastic body, the middle cross-supporting section is placed in the accommodating groove, and the front secondary locking extension section and the rear secondary locking extension section are subjected to the lateral pushing force and are bent and deformed by 90 degrees in opposite directions, and work together to achieve the limitation of the relative position of the middle cross-supporting section.

[0011] By adopting the above technical solution, the terminal block is embedded in an insulating plastic body, and is provided with a left-mounted plug-in top contact section for realizing top contact with the left-mounted cable and a right-mounted plug-in top contact section for realizing top contact with the right-mounted cable. When the left-mounted cable is inserted into place relative to the left-mounted plug-in top contact section, the left-mounted plug-in top contact section can be quickly and reliably realized by pulling the left-mounted flip piece; when the right-mounted cable is inserted into place relative to the right-mounted plug-in top contact section, the right-mounted flip piece can be quickly and reliably realized by pulling the right-mounted plug-in top contact section. At this time, the conduction between the left-mounted cable and the right-mounted cable is realized. From the above description, it can be seen that compared with the soft cable extension adapter board of the traditional design structure, the use of the PCB board is eliminated in the technical solution disclosed in the present invention. In this way, on the one hand, a large number of welding operations with the mainboard are saved, and when the model and specification of the flexible cable extension adapter board need to be adjusted, the left-placed cable and the right-placed cable can be removed, and then the flexible cable extension adapter board can be directly replaced without the need to remove the solder joints or re-soldering operations. The whole process is convenient and fast. On the other hand, the left-placed cable and the right-placed cable are directly connected through the wiring terminals, thereby eliminating the cause of the current short circuit from the root, and effectively ensuring the stability and reliability of the signal transmission process.

DETAILED DESCRIPTION

[0034] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by the terms "left", "right", "up", "down", "front", "back", etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0035] The flexible cable extension adapter plate is used to achieve the transition connection between the left and right cables. Figure 2-6As shown in Figures 12-15, it can be seen that the flexible cable extension adapter plate is mainly composed of several parts such as an insulating plastic body 1, a terminal unit 2, a left-placed flip piece 3 and a right-placed flip piece 4. Among them, the terminal unit 2 is composed of a plurality of terminals 21 inserted in the insulating plastic body 1 and arranged in a linear array along the front-to-back direction. From left to right, the terminal 21 is sequentially connected by a left-placed plug-in top contact section 211, a middle fixed section 212 and a right-placed plug-in top contact section 213. An intermediate plug-in slot 11 is provided on the insulating plastic body 1 for inserting the middle fixed section 212 and for limiting the position of the middle fixed section 212. The left-placed plug-in top contact section 211 and the right-placed plug-in top contact section 213 are both formed by the reverse extension of the middle fixed section 212, so as to be used to touch and conduct the left-placed cable and the right-placed cable respectively. The left flip member 3 is hinged to the insulating plastic body 1 and can be freely swung, and crosses the left mating top contact section 211. When the left flip member 3 is pulled, the left mating top contact section 211 is elastically deformed to achieve the clamping / relaxing operation of the left-mounted flat cable. The right flip member 4 is hinged to the insulating plastic body 1 and can be freely swung, and crosses the right mating top contact section 213. When the right flip member 4 is pulled, the right mating top contact section 213 is elastically deformed to achieve the clamping / relaxing operation of the right-mounted flat cable.

[0036] As can be seen from the above description, the use of the traditional PCB board is eliminated in the flexible cable extension adapter board disclosed in this embodiment. In this way, on the one hand, a large number of welding operations with the main board are omitted, and when the model and specification of the flexible cable extension adapter board need to be adjusted, the left-mounted cable and the right-mounted cable can be removed, and then the flexible cable extension adapter board can be directly replaced with a new one without the need to remove the solder joints or re-soldering operations. The whole process is convenient and fast. On the other hand, the left-mounted cable and the right-mounted cable are directly connected through the terminal 21, thereby eliminating the cause of the current short circuit from the root, thereby effectively ensuring the stability and reliability of the signal transmission process.

[0037] In order to improve the efficiency of left-mounted and right-mounted cable insertion and removal, and to simplify the design structure as much as possible and reduce the manufacturing cost, as a further optimization of the above-mentioned flexible cable extension adapter plate structure, such as Fig.14 , 15As shown in , the left-mounted plug-in top contact section 211 preferably includes a first top contact arm 2111 and a second top contact arm 2112. The first top contact arm 2111 is formed by the left side wall of the middle fixed section 212 continuing to extend to the left, and is embedded in the insulating plastic body 1. The second top contact arm 2112 is formed by the lower side wall of the first top contact arm 2111 continuing to extend downward, and then bending to the left. The right-mounted plug-in top contact section 213 preferably includes a third top contact arm 2131 and a fourth top contact arm 2132. The third top contact arm 2131 is formed by the right side wall of the middle fixed section 212 continuing to extend to the right, and is embedded in the insulating plastic body 1. The fourth top contact arm 2132 is formed by the lower side wall of the third top contact arm 2131 continuing to extend downward, and then bending to the right. When the left-mounted flip member 3 is hinged relative to the insulating plastic body 1, it crosses between the first top contact arm 2111 and the second top contact arm 2112. When the right flip member 4 is hinged relative to the insulating plastic body 1, it crosses between the third top contact arm 2131 and the fourth top contact arm 2132. When performing the mating operation of the left-placed cable, first insert the left-placed cable relative to the left-placed mating top contact section 211, and then move the left-placed flip member 3 in the counterclockwise direction. At this time, the first top contact arm 2111 is always fixed in position due to being embedded in the insulating plastic body 1. The pushing force acting on the second top contact arm 2112 is gradually eliminated as the left-placed flip member 3 is moved. The second top contact arm 2112 elastically recovers and deforms toward the first top contact arm 2111, thereby achieving stable and reliable top contact with the left-placed cable. When performing the mating operation of the right-mounted cable, the right-mounted cable is first inserted into place relative to the right-mounted mating top contact section 213, and then the right-mounted flip member 4 is moved in the clockwise direction. At this time, the third top contact arm 2131 is always kept in a fixed position due to being embedded in the insulating plastic body 1, and the pushing force acting on the fourth top contact arm 2132 is gradually eliminated as the right-mounted flip member 4 is moved. The fourth top contact arm 2132 is elastically restored to deform toward the third top contact arm 2131, thereby achieving stable and reliable top contact of the right-mounted cable (such as Figure 6 ).

[0038] It is known that when performing the removal and insertion operations of the left-mounted and right-mounted flat cables, it is necessary to repeatedly turn the left-mounted flip member 3 and the right-mounted flip member 4 to open and close. Over time, the hinged area on the insulating plastic body 1 used to limit the left-mounted flip member 3 and the right-mounted flip member 4 will inevitably be worn, which is not only difficult to repair, but also seriously reduces the normal service life of the flexible cable to extend the adapter board, and also reduces the position accuracy of the left-mounted flip member 3 and the right-mounted flip member 4 after being rotated into place, thereby reducing the top contact stability of the left-mounted and right-mounted flat cables after being inserted. In view of this, if Figure 2 , 3As shown in , 4, as a further optimization of the above-mentioned flexible flat cable extension adapter structure, it can also be additionally provided with a front auxiliary reinforcement 5 and a rear auxiliary reinforcement 6 according to actual conditions and customer needs. The front auxiliary reinforcement 5 and the rear auxiliary reinforcement 6 are arranged along the left and right directions and are both embedded in the insulating plastic body 1. Fig.12 , 13 As shown in FIG, a front plug-in slot 12 and a rear plug-in slot 13 are provided in the insulating plastic body 1 for inserting the front auxiliary reinforcement member 5 and the rear auxiliary reinforcement member 6. Fig.16 , 17 As shown in , a first front limit groove 51 and a second front limit groove 52 are provided on the front auxiliary reinforcement member 5. Fig.18 As shown in FIG, a first rearward limiting groove 61 and a second rearward limiting groove 62 are provided on the rearward auxiliary reinforcement member 6. Figure 3 As shown in , after the front auxiliary reinforcement member 5 and the rear auxiliary reinforcement member 6 are plugged in with the insulating plastic body 1, the first front limit groove 51 and the first rear limit groove 61 are opposite to each other and are partially exposed to the outside of the insulating plastic body 1, and cooperate to limit the position of the left-mounted flip member 3. The second front limit groove 52 and the second rear limit groove 62 are opposite to each other and are partially exposed to the outside of the insulating plastic body 1, and cooperate to limit the position of the right-mounted flip member 4. In this way, only the operation of the left-mounted flip member 3 is used as an example to illustrate. In the process of performing the pulling operation on the left-mounted flip member 3, the left-mounted flip member 3 is always supported and limited in position by the first front limit groove 51 and the first rear limit groove 61, thereby avoiding the occurrence of wear on the insulating plastic body 1, and further ensuring that the left-mounted flip member 3 always maintains a high movement accuracy over a long period of time, and finally ensuring the stable and reliable contact with the left-mounted cable and the smooth execution of the rapid removal operation (such as Figure 8 , 9 ).

[0039] In order to ensure the plugging stability of each connection terminal 21 in the insulating plastic body 1 and prevent it from coming out in actual application, Figure 2 , 3 As shown in , 4, the flexible flat cable extension adapter is further provided with a locking member 7. The locking member 7 is inserted into the insulating plastic body 1 and simultaneously supports each terminal 21 horizontally. After each terminal 21 is inserted into the insulating plastic body 1, the locking member 7 is inserted toward the bottom wall of the insulating plastic body 1 to simultaneously apply an upward push force to each terminal 21 to ensure the insertion stability of the middle fixed section 212 in the middle insertion groove 11 (as shown in FIG. Figure 6 , 7 ).

[0040] It is known that the locking member 7 can adopt a variety of design structures to achieve reliable mating with the insulating plastic body and reliable support of the terminal unit 2. However, a design structure is simple, easy to implement, and has a high assembly efficiency. The specific implementation is as follows: Fig.19 As shown in , the locking member 7 is preferably formed by connecting a front clamping arm unit 71, a middle horizontal supporting section 72 and a rear clamping arm unit 73 in sequence. The front clamping arm unit 71 includes a first front clamping arm 711 and a second front clamping arm 712 disposed opposite to each other along the left-right direction. The rear clamping arm unit 73 includes a first rear clamping arm 731 and a second rear clamping arm 732 disposed opposite to each other along the left-right direction. The first front clamping arm 711, the second front clamping arm 712, the first rear clamping arm 731 and the second rear clamping arm 732 are all formed by continuing to extend upward from the upper plane of the middle horizontal supporting section 72. Extending upward from the bottom wall of the insulating plastic body 1 are the first front clamping groove 14, the second front clamping groove 15, the first rear clamping groove 16, and the second rear clamping groove 17 for inserting the first front clamping arm 711, the second front clamping arm 712, the first rear clamping arm 731, and the second rear clamping arm 732, respectively. Extending upward from the bottom wall of the insulating plastic body 1 is an accommodating groove 18 for inserting the middle cross-supporting section 72. Taking the first front clamping arm 711 as an example, it continues to extend from its free end and folds outward 90 degrees to form a first hooking portion 7111. Fig.12 As shown in , a first limiting boss 141 for limiting the axial displacement of the first hooking portion 7111 is formed in the first front clamping groove 14. When the wiring terminal unit 2 is plugged with the insulating plastic body 1, the locking member 7 moves toward the insulating plastic body 1 to perform the plugging action. At this time, the first front clamping arm 711, the second front clamping arm 712, the first rear clamping arm 731, and the second rear clamping arm 732 slide along the first front clamping groove 14, the second front clamping groove 15, the first rear clamping groove 16, and the second rear clamping groove 17 respectively until the locking member 7 and the insulating plastic body 1 are completely fixed. Taking the plugging action of the first front clamping arm 711 and the first front clamping slot 14 as an example, when the locking member 7 is plugged in relative to the insulating plastic body 1, the first hook portion 7111 always elastically contacts the inner wall of the first front clamping slot 1 and slides along the inner wall of the first front clamping slot 1 until the first hook portion 7111 completely passes over the first limiting boss 141. At this time, the axial position of the first front clamping arm 711 is locked. The plugging principle and plugging process of the second front clamping arm 712, the first rear clamping arm 731 and the second rear clamping arm 732 completely complete the operation of the first front clamping arm 711 (such as Fig.10 , 11 ).

[0041] like Figure 16-18As shown in the figure, corresponding to the receiving groove 18, the front secondary locking extension section 53 and the rear secondary locking extension section 63 are formed on the front auxiliary reinforcement member 5 and the rear auxiliary reinforcement member 6 respectively. When the locking member 7 is inserted with respect to the insulating plastic body 1, the middle cross-supporting section 72 is placed in the receiving groove 18, and the front secondary locking extension section 53 and the rear secondary locking extension section 63 are subjected to the lateral pushing force and are bent and deformed by 90 degrees in opposite directions, and cooperate to achieve the limitation of the relative position of the middle cross-supporting section 72 (as shown in FIG. Figure 7 ). When the locking member 7 is plugged into the insulating plastic body 1, the first front clamping arm 711, the second front clamping arm 712, the first rear clamping arm 731, and the second rear clamping arm 732 are used to achieve a primary position locking with the insulating plastic body 1, and then, a side thrust is applied to the front secondary locking extension section 53 and the rear secondary locking extension section 63 to bend and deform, so as to achieve a secondary position locking of the locking member 7. In this way, the plugging reliability of the locking member 7 in the insulating plastic body 1 is effectively guaranteed through two measures, thereby avoiding the subsequent position change of each terminal 21 relative to the insulating plastic body 1 due to the plugging force or external force, and finally ensuring that it has a good top contact with the left and right wiring at the same time.

[0042] Finally, it should be noted that in order to facilitate those skilled in the art to more easily understand the above technical solution, Fig. 20 A schematic diagram showing the application state of the flexible flat cable extension adapter plate of the present invention is shown.

Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
