[0038] The connector 10 according to an embodiment of the present utility model will be described below with reference to the accompanying drawings.

[0039] As Figures 1 to 13 shown, the connector 10 according to an embodiment of the present utility model includes: an installation part 1 and terminals 2. The two side surfaces of the installation part 1 opposite to each other in the first direction e1 are a first side surface 11 and a second side surface 12 respectively. An installation hole 13 and a connection hole 14 are formed in the installation part 1. The installation hole 13 extends along the first direction e1 to the first side surface 11 and is provided with a plurality of them arranged at intervals in the second direction e2. The second direction e2 is perpendicular to the first direction e1. The connection hole 14 extends along the first direction e1 and is located on the side of the installation hole 13 away from the first side surface 11. The connection hole 14 extends to the second side surface 12 and communicates with the plurality of installation holes 13.

[0040] That is to say, in the first direction e1, one end of the plurality of installation holes 13 extends to the first side surface 11, one end of the connection hole 14 extends to the second side surface 12, and the ends of the plurality of installation holes 13 away from the first side surface 11 communicate with the ends of the connection hole 14 away from the second side surface 12, so that a plurality of installation spaces for installing the terminals 2 can be jointly formed by the connection hole 14 and the plurality of installation holes 13.

[0041] Among them, the terminal 2 is adapted to be connected to the wire 20 and includes a connected main body part 21 and a connection part 22. The connection part 22 is used to connect to the wire 20. The main body part 21 is located in the installation hole 13, and the connection part 22 is located in the connection hole 14. That is to say, the plurality of installation holes 13 and the connection hole 14 cooperate to form an installation space for installing a plurality of terminals 2 in the installation part 1. After the plurality of terminals 2 are connected to the wire 20 and installed in the installation part 1, the main body parts 21 of the plurality of terminals 2 are respectively located in the corresponding installation holes 13. The terminal 2 is connected to the wire 20 through the connection part 22, and the connection part 22 is located in the connection hole 14. The connection positions of the plurality of terminals 2 and the wire 20 are all located in the connection hole 14.

[0042] Among them, there are many types of wires 20, such as common ordinary wires 20 like copper core wires and aluminum core wires, as well as flat wires 20 such as FFC / FPC. Among them, the difference between the flat wire 20 and the ordinary wire 20 is that the flat wire 20 includes a plurality of conductive sheets spaced apart in the insulating layer, and adjacent conductive sheets are connected through the insulating layer to form the flat wire 20 into an integral structure. In this application, the connecting portion 22 is placed in a complete connecting hole 14, so that after the ordinary wire 20 is connected to the connecting portion 22, it is inserted into the connecting hole 14. When the flat wire 20 is connected to the connecting portion 22 and inserted into the connecting hole 14, the insulating layer portion connecting adjacent conductive sheets can also be inserted into the connecting hole 14. In other words, the connecting hole 14 can be applicable to both the ordinary wire 20 and the integral flat wire 20, thereby better improving the applicable range of the connector 10.

[0043] According to the connector 10 of the first aspect embodiment of the present invention, the connecting portion 22 is placed in a complete connecting hole 14, so that the connecting hole 14 can be applicable to the installation of both the ordinary wire 20 and the integral flat wire 20, thereby better improving the applicable range of the connector 10.

[0044] In some embodiments, a plurality of terminals 2 can be arranged in a certain order, and the plurality of conductive sheets of the integral flat wire 20 are respectively aligned with the connecting portions 22 of the plurality of terminals 2 and fixed, so that the flat wire 20 can be crimped onto the plurality of terminals 2 at one time, thereby improving the connection efficiency between the wire 20 and the plurality of terminals 2. Specifically, two sets of crimping wings 221 are formed on the connecting portion 22 along the second opposite sides. After the flat wire 20 is placed on the connecting portion 22, the conductive sheets are located between the crimping wings 221 on both sides. The crimping wings 221 can penetrate the insulating layer and bend towards each other to press the conductive sheets.

[0045] According to some embodiments of the present utility model, a plurality of stoppers 141 arranged at intervals along the second direction e2 are formed on at least one inner wall surface of the connection hole 14 in the third direction e3. The third direction e3 is perpendicular to the first direction e1 and the second direction e2. In the second direction e2, a connection space 142 is defined between any two adjacent stoppers 141. The number of connection spaces 142 is the same as that of the mounting holes 13 and they are in one-to-one correspondence and communication. The connecting portion 22 is located in the connection space 142. That is to say, the stopper 141 is located between the connection spaces 142 on both sides. After the terminal 2 is connected to the wire 20 and installed in the installation portion 1, the connection position between the terminal 2 and the wire 20 is located in the connection space 142. That is, one end of the wire 20 connected to the terminal 2 is located in the connection space 142. At this time, the stopper 141 is located between the connecting portions 22 on both sides. Thus, the connecting portions 22 on both sides can be well separated by the stopper 141, thereby avoiding the short-circuit risk caused by the contact between two adjacent connecting portions 22 or wires 20, which is beneficial to improving the safety performance of the connector 10.

[0046] Among them, it should be noted that it may be that only a plurality of stoppers 141 arranged at intervals along the second direction e2 are formed on one inner wall surface of the connection hole 14 in the third direction e3, and there is a gap between the stopper 141 and the other inner wall surface of the connection hole 14 in the third direction e3, so as to ensure that two adjacent connection spaces 142 are connected to adapt to the integrated flat wire 20. Of course, it may also be that a plurality of stoppers 141 arranged at intervals along the second direction e2 are formed on both inner wall surfaces of the connection hole 14 in the third direction e3, and there is a gap between the stoppers 141 on the two side surfaces, so as to ensure that two adjacent connection spaces 142 are connected to adapt to the integrated flat wire 20, and so on. Examples are not given one by one here.

[0047] According to some embodiments of the present utility model, the stopper 141 is in a strip shape extending along the first direction e1 and has the same length as the connection hole 14 in the first direction e1. That is to say, the stopper 141 extends from the second side surface 12 along the first direction e1 to the end where the connection hole 14 is connected to the mounting hole 13. Thus, the stopper 141 can completely cover the connection hole 14 in the first direction e1, thereby improving the stability of the stopper 141 to prevent the connecting portions 22 and the ordinary wire 20 in the connection spaces 142 on both sides from approaching each other.

[0048] According to some embodiments of the present utility model, in the third direction e3, a communication channel 143 is defined between the stop block 141 and the inner wall surface of the opposite connection hole 14 or between the opposite stop blocks 141, which communicates the adjacent two connection spaces 142. The ratio range of the height of the communication channel 143 to the height of the connection hole 14 is 0.3 - 0.6. That is, the height of the communication channel 143 in the third direction e3 is controlled within the range of 0.3 times to 0.6 times the height of the connection hole 14 in the third direction e3. For example, the height of the communication channel 143 in the third direction e3 can be 0.3, 0.35, 0.4, 0.45, 0.5, 0.55, 0.6, etc. of the height of the connection hole 14 in the third direction e3, and no specific limitation is made here.

[0049] It can be understood that, based on the certain height of the connection hole 14, the larger the ratio of the height of the communication channel 143 to the height of the connection hole 14, the larger the height value of the communication channel 143, and the smaller the occlusion between the adjacent two connection spaces 142, but the smaller the height dimension of the stop block 141 in the third direction e3, and the worse the blocking effect on the connecting portion 22 and the wire 20; conversely, the smaller the ratio of the height of the communication channel 143 to the height of the connection hole 14, the smaller the height value of the communication channel 143, and the larger the occlusion between the adjacent two connection spaces 142, but the larger the height dimension of the stop block 141 in the third direction e3, and the higher the blocking effect on the connecting portion 22 and the wire 20. Thus, controlling the ratio range of the height of the communication channel 143 to the height of the connection hole 14 within the range of 0.3 to 0.6 can avoid the too small size of the stop block 141 in the third direction e3 from affecting the blocking effect of the stop block 141 on the connecting portion 22 and the ordinary wire 20, and at the same time can avoid the too small connection space 142 from affecting the adaptation effect on the flat wire 20.

[0050] According to some embodiments of the present utility model, the mounting portion 1 has a locking groove 15 extending along the third direction e3, and a plurality of mounting holes 13 communicate with the connection holes 14 through the locking groove 15. The connector 10 further includes a locking block 3, and the locking block 3 is switchably disposed in the locking groove 15 between a locking position and an unlocking position. In the locking position, the locking block 3 is used to restrict the movement of the terminal 2 in the first direction e1. In the unlocking position, the locking block 3 is spaced apart from the terminal 2. That is to say, in the first direction e1, the locking groove 15 is located between the mounting hole 13 and the connection hole 14 and communicates the mounting hole 13 and the connection hole 14. Therefore, when the terminal 2 is inserted into the mounting portion 1, the locking block 3 can be switched to the unlocking position to prevent the locking block 3 from interfering with the installation of the terminal 2. One end of the main body portion 21 away from the connecting portion 22 is inserted into the connection hole 14 from the second end face and enters the mounting hole 13 through the locking groove 15. Therefore, after the terminal 2 is inserted into the mounting portion 1, the portions of the plurality of terminals 2 located between the connection hole 14 and the mounting hole 13 are all located in the locking groove 15. At this time, the locking block 3 is switched from the unlocking position to the locking position to limit all the terminals 2 to improve the connection stability between the terminal 2 and the mounting portion 1. At the same time, the locking steps for the plurality of terminals 2 can be simplified, such as not needing to lock the terminals 2 one by one, which is beneficial to improving the assembly efficiency of the terminal 2 and the mounting portion 1.

[0051] In a specific example, the mounting portion 1 is an integrally formed part, and the opening of the locking groove 15 is formed on the side surface of the mounting portion 1 in the third direction e3.

[0052] In another specific example, the mounting portion 1 includes a sheath 16 and a core 17 that are separately and independently formed, and the opening of the locking groove 15 is formed on the side surface of the core 17 in the third direction e3.

[0053] According to some embodiments of the present utility model, the locking block 3 is movable relative to the locking groove 15 along the third direction e3 to switch between the locking position and the unlocking position. A communication hole 31 penetrating along the first direction e1 is formed on the locking block 3. In the third direction e3, the side wall of the communication hole 31 adjacent to the opening of the locking groove 15 constitutes a locking portion 32. A locking cooperation portion 23 is formed on the terminal 2. In the locking position, the locking portion 32 abuts against the locking cooperation portion 23 along the first direction e1. In the unlocking position, the locking portion 32 is spaced apart from the locking cooperation portion 23 along the third direction e3, and the terminal 2 is movable relative to the communication hole 31 along the first direction e1.

[0054] That is to say, when the terminal 2 is installed on the installation part 1 or removed from the installation part 1, by switching the locking block 3 to the unlocking position, the locking part 32 is located on one side of the locking engagement part 23 in the third direction e3 at this time, so as to avoid the contact between the locking engagement part 23 and the locking part 32 when the terminal 2 moves in the first direction e1, ensuring the smooth installation or disassembly of the terminal 2; after the terminal 2 is installed in the installation part 1, by switching the locking block 3 to the locking position, the locking part 32 is located on one side of the locking engagement part 23 in the first direction e1, so as to better limit the movement of the locking engagement part 23 in the first direction e1.

[0055] In a specific example, the connection position between the main body part 21 and the connection part 22 constitutes the locking engagement part 23, and the terminal 2 is adapted to be inserted into the installation part 1 along the direction from the second side surface 12 to the second side surface 12. In the locking position, the locking part 32 is located on the side of the locking engagement part 23 away from the first side surface 11, so as to avoid the terminal 2 from disengaging from the installation part 1 along the direction from the first side surface 11 to the second side surface 12.

[0056] According to some embodiments of the present invention, a guiding block 33 is formed on the side surface of the locking part 32 facing the connection hole 14, and the side surface of the guiding block 33 away from the locking part 32 is formed as a guiding surface 331. In the direction from the second side surface 12 to the first side surface 11, the guiding surface 331 extends obliquely in the direction away from the locking part 32. Therefore, during the process of installing the terminal 2 into the installation part 1, after the end of the main body part 21 away from the connection part 22 contacts the guiding surface 331, it can move in the direction away from the locking part 32 under the guidance of the guiding surface 331, so as to avoid jamming when the terminal 2 is installed. In addition, the terminal 2 can be guided to the accurate installation position through the guiding surface 331. For example, to reduce the insertion difficulty of the terminal 2, the size of the connection hole 14 is usually slightly larger than the size of the main body part 21. Therefore, when the end of the main body part 21 away from the connection part 22 has a position deviation, it can be accurately inserted into the installation hole 13 under the action of the guiding surface 331, reducing the installation difficulty of the terminal 2 and improving the installation efficiency of the terminal 2.

[0057] In some embodiments, buckles 34 are formed on both side surfaces of the locking block 3 in the second direction e2, and clamping interfaces 151 are formed on the inner wall surfaces of the two opposite sides of the locking groove 15 in the second direction e2, and the buckles 34 are clamped and connected with the clamping interfaces 151.

[0058] According to some embodiments of the present utility model, the installation part 1 includes a sheath 16 and an inner core 17. An installation cavity 161 is formed inside the sheath 16. The inner core 17 is detachably arranged inside the installation cavity 161. The installation hole 13 and the connection hole 14 are both formed on the inner core 17. That is to say, the sheath 16 and the inner core 17 are detachably connected. Therefore, during the assembly process of the connector 10, the inner core 17 of the corresponding model can be selected according to the digital requirements of different numbers of wires 20 and installed inside the sheath 16, which is beneficial to improving the flexibility of the use of the limiter.

[0059] According to some embodiments of the present utility model, a pair of buckle parts 162 are arranged on both opposite sides of the inner core 17 in the second direction e2 inside the installation cavity 161. A pair of clamping blocks 171 are formed on both opposite side surfaces of the inner core 17 in the second direction e2. The clamping blocks 171 are in one-to-one clamping fit with the buckle parts 162. That is to say, the inner core 17 is fixed inside the installation cavity 161 through the one-to-one clamping fit between the clamping blocks 171 and the buckle parts 162, that is, the inner core 17 and the sheath 16 are clamped and connected. Thus, the connection structure between the inner core 17 and the sheath 16 can be better simplified, and the difficulty of establishing the cooperation relationship and releasing the cooperation relationship is low, so that the assembly and disassembly difficulty between the sheath 16 and the inner core 17 can be reduced. In addition, the connection position between the inner core 17 and the sheath 16 is inside the sheath 16, which can avoid accidental contact with the buckle parts 162 resulting in the connection failure between the inner core 17 and the sheath 16, and is beneficial to improving the connection stability between the inner core 17 and the sheath 16.

[0060] Specifically, the buckle part 162 is spaced apart from the inner wall surface of the installation cavity 161, so as to ensure that the buckle part 162 has good elasticity.

[0061] According to some embodiments of the present utility model, a first limiting protrusion 172 is arranged on one of the inner wall surface of the installation cavity 161 and the outer wall surface of the inner core 17, and a first limiting sliding groove 163 extending along the first direction e1 is arranged on the other of the inner wall surface of the installation cavity 161 and the outer wall surface of the inner core 17. The first limiting protrusion 172 is slidably arranged inside the first limiting sliding groove 163 along the first direction e1. Therefore, during the assembly process of the inner core 17 and the sheath 16, the first limiting protrusion 172 is aligned with the first limiting sliding groove 163 and inserted. The installation angle of the inner core 17 relative to the sheath 16 is limited by the limitation of the first limiting sliding groove 163 on the first limiting protrusion 172, which is beneficial to reducing the assembly difficulty between the inner core 17 and the sheath 16. In addition, the limiting positions between the inner core 17 and the sheath 16 can be increased, which is beneficial to improving the connection stability between the inner core 17 and the sheath 16.

[0062] According to some embodiments of the utility model, a second limiting protrusion 211 is formed on the main body 21, and a second limiting slide groove 131 extending along the first direction e1 is formed on the inner wall surface of the mounting hole 13, and the limiting protrusion is slidably arranged in the second limiting slide groove 131 along the first direction e1. Therefore, in the process of inserting the terminal 2 into the mounting portion 1, the second limiting protrusion 211 is aligned with the second limiting slide groove 131 and inserted, and the second limiting slide groove 131 limits the installation angle of the terminal 2 relative to the mounting portion 1, which is conducive to reducing the difficulty of installing the terminal 2. In addition, the second limiting slide groove 131 can better improve the connection stability between the terminal 2 and the mounting portion 1 by limiting the second limiting protrusion 211.

[0063] According to some embodiments of the utility model, a limiting spring piece 212 is provided on the main body 21, and a limiting block 132 is provided on the inner wall surface of the mounting hole 13. The limiting spring piece 212 can move between a clamping position and an avoidance position. In the clamping position, the limiting spring piece 212 is clamped and matched with the limiting block 132, and in the avoidance position, the limiting spring piece 212 is spaced apart from the limiting block 132. In other words, the main body 21 is clamped and connected with the mounting portion 1 through the cooperation between the limiting spring piece 212 and the limiting block 132, so as to limit the freedom of movement of the terminal 2 relative to the mounting portion 1 in the first direction e1, which is conducive to improving the stability of the connection between the terminal 2 and the mounting portion 1.

[0064] Specifically, in the clamping position, the limiting spring piece 212 extends upwardly and obliquely in the direction toward the connection portion 22, and the end of the limiting spring piece 212 facing away from the connection portion 22 is arranged on the main body 21, and when the terminal 2 is inserted into the mounting hole 13 in the direction from the second side surface 12 to the first side surface 11, the limiting block 132 can squeeze the limiting spring piece 212 to switch from the clamping position to the avoidance position, so that the limiting spring piece 212 can pass through the part of the mounting hole 13 where the limiting block 132 is provided, and when the limiting spring piece 212 is located on the side of the limiting block 132 facing the first side surface 11, the limiting spring piece 212 restores its deformation and switches from the avoidance position to the clamping position, and the free end of the limiting spring piece 212 is located on the side of the limiting block 132 facing the first side surface 11, so that the terminal 2 can be prevented from moving in the direction from the first side surface 11 to the second side surface 12 by limiting the limiting spring piece 212 by the limiting block 132. In addition, a disassembly hole 18 extending along the first direction e1 and opposite to the limiting spring piece 212 is formed on the first side surface 11 of the mounting portion 1. The disassembly hole 18 allows a disassembly member to extend into and contact the limiting spring piece 212 to push the limiting spring piece 212 to switch from the clamping position to the avoidance position, thereby facilitating the disassembly of the terminal 2.

[0065] In a specific example, the connector 10 can be divided into a male connector 10a and a female connector 10b. The male connector 10a is plugged into the female connector 10b. The terminal 2 on the male connector 10a forms a plug, and a jack that is plugged and matched with the plug is formed on the terminal 2 of the female connector 10b. Moreover, an insertion space for the female connector 10b to insert is formed in the installation part 1 of the male connector 10a.
