Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a wiring connector. Background Technology

[0002] Wiring connectors are used to connect two electrical components to transmit signals or current. A wiring connector includes a housing and terminals that fit together. To improve the stability of the connection between the terminals and the housing, in related technologies, a terminal locking mechanism is typically used to lock the terminals to the housing after they are inserted. Specifically, a pre-locking structure and a final locking structure are provided between the terminal locking mechanism and the housing. The pre-locking structure locks the terminal locking mechanism in a pre-locked position, and the final locking structure locks the terminal locking mechanism in a final locked position.

[0003] However, in this type of connector, the pre-locking structure and the final locking structure are both located on the same side of the terminal locking member, which makes it difficult to control the locking force of the pre-locking structure and the final locking structure separately. When the terminal locking member is switched from the final locking position to the pre-locking position, it is easy for the terminal locking member to be pulled directly out of the housing, or even damage the terminal. Utility Model Content

[0043] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0044] like Figures 1-9As shown, this embodiment provides a wiring connector, including a housing 1 and a terminal locking member 2. The housing 1 can be inserted into a wiring terminal in a first direction; the terminal locking member 2 can be inserted into the housing 1 in a second direction, so that the terminal locking member 2 has a pre-locked position and a final-locked position, and the terminal locking member 2 can switch between the pre-locked position and the final-locked position; when the terminal locking member 2 is in the pre-locked position, the terminal locking member 2 and the housing 1 are locked by the pre-locking structure, and the terminal locking member 2 is separated from the wiring terminal; when the terminal locking member 2 is in the final-locked position, the terminal locking member 2 and the housing 1 are locked by the final-locking structure, so that the terminal locking member 2 locks the wiring terminal to the housing 1.

[0045] Furthermore, the final locking structure is located on one side of the terminal locking member 2 along the first direction. The pre-locking structure includes a pre-locking component one, which can prevent the terminal locking member 2 from separating from the housing 1. The pre-locking component one is located on one side of the terminal locking member 2 along the third direction; the first direction, the second direction, and the third direction are perpendicular to each other.

[0046] In this embodiment, the connector uses a pre-locking component 1 located on one side of the terminal locking member 2 along a third direction, and a final locking structure located on one side of the terminal locking member 2 along a first direction. This allows for separate control of the locking forces of the pre-locking component 1 and the final locking structure. For example, the locking force of the pre-locking component 1 can be made greater than the locking force of the final locking structure. This ensures that the terminal locking member 2 can not only smoothly switch from the final locking position to the pre-locking position, but also prevents the terminal locking member 2 from being pulled directly out of the housing 1 when switching from the final locking position to the pre-locking position. This improves ease of use while protecting the terminal.

[0047] It should be noted that after the terminal locking member 2 is locked to the housing 1 by the pre-locking structure or the final locking structure, the terminal locking member 2 can still remain in the pre-locking position or the final locking position when it is not subjected to external force or is subjected to a slight external force; of course, by applying force to the terminal locking member 2, the terminal locking member 2 can be switched between the pre-locking position and the final locking position, or the terminal locking member 2 can be pulled out of the housing 1.

[0048] The locking force of the pre-locking component is greater than the locking force of the final locking structure. That is, when the terminal locking member 2 is pulled out from the housing 1, the force required to be applied to the terminal locking member 2 is T1; when the terminal locking member 2 is switched from the final locking position to the pre-locking position, the force required to be applied to the terminal locking member 2 is T2; T1 > T2.

[0049] The wiring connector of this embodiment, by setting the pre-locking component 1 on one side of the terminal locking member 2 along the third direction and the final locking structure on one side of the terminal locking member 2 along the first direction, can also improve the design flexibility of the terminal locking member 2 and the housing 1, thereby improving the versatility of the terminal locking member 2, so that the terminal locking member 2 can be adapted to different models of housing 1.

[0050] Optionally, the pre-locking structure further includes a second pre-locking component. The direction of the force exerted by the second pre-locking component on the terminal locking member 2 is opposite to the direction of the force exerted by the first pre-locking component on the terminal locking member 2, thereby locking the terminal locking member 2 in the pre-locked position. Furthermore, the second pre-locking component is located on one side of the terminal locking member 2 along the first direction, facilitating the unified adjustment of the locking forces of the second pre-locking component and the final locking structure. This allows the terminal locking member 2 to smoothly switch from the pre-locked position to the final locking position, improving the convenience of switching between the pre-locked and final locking positions.

[0051] Optionally, the pre-locking component includes a snap-fit ​​portion 21 provided on the terminal locking member 2 and a snap-fit ​​mating portion 11 provided on the housing 1. When the terminal locking member 2 is in the pre-locking position, the snap-fit ​​portion 21 can abut against the snap-fit ​​mating portion 11 in the direction in which the terminal locking member 2 is pulled out of the housing 1. This not only prevents the terminal locking member 2 from separating from the housing 1, in other words, prevents the terminal locking member 2 from being pulled out of the housing 1, but also simplifies the structure of the terminal locking member 2 and the housing 1, improves the processing convenience of the terminal locking member 2 and the housing 1, and helps to reduce costs.

[0052] Optionally, the pre-locking component two includes a second snap-fit ​​portion 22 provided on the terminal locking member 2 and a second snap-fit ​​mating portion 12 provided on the housing 1. When the terminal locking member 2 is in the pre-locking position, the second snap-fit ​​portion 22 can abut against the second snap-fit ​​mating portion 12 in the direction in which the terminal locking member 2 is inserted into the housing 1. This not only prevents the terminal locking member 2 from being further inserted into the housing 1, in other words, prevents the terminal locking member 2 from switching from the pre-locking position to the final locking position, but also simplifies the structure of the terminal locking member 2 and the housing 1, improves the processing convenience of the terminal locking member 2 and the housing 1, and helps to reduce costs.

[0053] Optionally, the final locking structure includes a snap-fit ​​portion 23 provided on the terminal locking member 2 and a snap-fit ​​mating portion 13 provided on the housing 1. When the terminal locking member 2 is in the final locking position, the terminal locking member 2 can abut against the terminal in the direction of its insertion into the housing 1, and the snap-fit ​​portion 23 can abut against the snap-fit ​​mating portion 13 in the direction of the terminal locking member 2 being pulled out of the housing 1. This can press the terminal against the housing 1 to lock the terminal and the housing 1, and can also simplify the structure of the terminal locking member 2 and the housing 1, improve the processing convenience of the terminal locking member 2 and the housing 1, and help reduce costs.

[0054] In this embodiment, the first snap-fit ​​part 21 is provided on one side of the terminal locking member 2 along the third direction, and the first snap-fit ​​part 21 is a snap-fit ​​boss; the housing 1 is provided with a locking insertion hole 14 for the terminal locking member 2 to be inserted, the locking insertion hole 14 includes two first sidewalls arranged opposite to each other along the third direction, and the first snap-fit ​​mating part 11 is provided on the first sidewall, and the first snap-fit ​​mating part 11 is a hook.

[0055] Furthermore, the terminal locking member 2 has a second snap-fit ​​boss on one side along the first direction. Furthermore, the locking hole 14 also includes two second sidewalls arranged opposite each other along the first direction, each sidewall having a snap-fit ​​engagement boss corresponding to the second snap-fit ​​boss. Specifically, the second snap-fit ​​boss includes a first end and a second end arranged opposite each other along the second direction. The first end is located on the side of the second snap-fit ​​boss along the direction in which the terminal locking member 2 is inserted into the housing 1, and the second end is located on the side of the second snap-fit ​​boss along the direction in which the terminal locking member 2 is pulled out of the housing 1. The first end is the second snap-fit ​​part 22, and the second end is the third snap-fit ​​part 23. The snap-fit ​​engagement boss includes a third end and a fourth end arranged opposite each other along the second direction. The third end is located on the side of the snap-fit ​​engagement boss along the direction in which the terminal locking member 2 is pulled out of the housing 1, and the fourth end is located on the side of the snap-fit ​​engagement boss along the direction in which the terminal locking member 2 is inserted into the housing 1. The third end is the second snap-fit ​​part 12, and the fourth end is the third snap-fit ​​part 13.

[0056] Optionally, the snap-fit ​​part 21 and / or the snap-fit ​​mating part 11 are provided with a guide structure. The guide structure is used to guide the terminal locking member 2 to move along the direction of its insertion into the housing 1, thereby improving the smoothness of the terminal locking member 2 when it is inserted into the housing 1 and moves toward the pre-locked position, which is conducive to further improving the ease of use.

[0057] For example, the snap-fit ​​part 21 is provided with a guide structure 1, which is a first inclined surface 211. The first inclined surface 211 is provided on one side of the snap-fit ​​part 21 along the direction in which the terminal locking member 2 is inserted into the housing 1. The first inclined surface 211 is inclined towards the terminal locking member 2 along the direction in which the terminal locking member 2 is inserted into the housing 1.

[0058] Optionally, the second snap-fit ​​part 22 and / or the second snap-fit ​​mating part 12 are provided with a second guide structure. The second guide structure is used to guide the terminal locking member 2 to move along the direction in which it is inserted into the housing 1, thereby improving the smoothness of the terminal locking member 2 switching from the pre-locked position to the final locked position, which is conducive to further improving the ease of use.

[0059] For example, the second snap-fit ​​part 12 is provided with a second guide structure, which is a second inclined surface 121. The second inclined surface 121 is provided on one side of the second snap-fit ​​part 12 along the direction of the terminal locking member 2 being pulled out of the housing 1. Along the third direction from the second snap-fit ​​part 12 to the second snap-fit ​​part 22, the second inclined surface 121 is inclined towards the direction close to the third snap-fit ​​part 13.

[0060] Optionally, the locking part 23 and / or the locking engagement part 13 are provided with a guide structure 3, which guides the terminal locking member 2 to move in the direction of its pull-out from the housing 1, thereby improving the smoothness of the terminal locking member 2 switching from the final locking position to the pre-locking position and further improving the ease of use.

[0061] For example, the snap-fit ​​part 3 13 is provided with a guide structure 3, which is a third inclined surface 131. The third inclined surface 131 is provided on one side of the snap-fit ​​part 3 13 along the direction of the terminal locking member 2 being inserted into the housing 1. Along the third direction from the snap-fit ​​part 3 13 to the snap-fit ​​part 3 23, the third inclined surface 131 is inclined toward the snap-fit ​​part 2 12.

[0062] Optionally, the housing 1 can be plugged into multiple terminals. Further, the terminal locking member 2 includes multiple locking portions 24, which are staggered along a first direction. Each locking portion 24 is provided with a terminal positioning structure 243. When the terminal locking member 2 is in the final locked position, the terminal positioning structures 243 of the multiple locking portions 24 respectively abut against the multiple terminals. This allows the connector to not only be compatible with multiple terminals but also improves the foolproof function of the terminal locking member 2, thereby enhancing the ease and efficiency of disassembly and assembly of the terminal locking member 2.

[0063] Optionally, among the multiple terminals, at least two terminals are of different models. That is to say, the connector in this embodiment is a hybrid connector, which can be compatible with different models of terminals, has stronger adaptability, and is also conducive to reducing costs.

[0064] Furthermore, the terminal positioning structures 243 of the multiple locking parts 24 respectively abut against different types of terminals; the terminal positioning structures 243 of the same locking part 24 abut against the same type of terminal. It should be noted that the different types of terminals are inserted into the housing 1 to different depths along the first direction. By staggering the multiple locking parts 24 along the first direction and abutting the terminal positioning structures 243 of different locking parts 24 against different types of terminals, and abutting the terminal positioning structures 243 of the same locking part 24 against the same type of terminal, the terminal positioning structures 243 of different locking parts 24 can be adapted to different types of terminals, thereby improving the connection stability between different types of terminals and the housing 1.

[0065] Specifically, the housing 1 is provided with multiple terminal sockets 15, and multiple terminals are inserted into the multiple terminal sockets 15 one by one. The size and shape of the terminal sockets 15 correspond to the terminals inserted into the terminal sockets 15, so that after the terminals are inserted into the corresponding terminal sockets 15, the elastic buckles of the terminals can catch the positioning steps provided on the housing 1, thereby initially locking the terminals.

[0066] Furthermore, the locking part 24 is provided with clearance holes 244 and missing parts 245 corresponding to the terminals. The sidewalls of each clearance hole 244, the end face of the missing part 245, and the end face of the locking part 24 form a terminal positioning structure 243. It should be noted that the size of the clearance holes 244 corresponding to different types of terminals is different, so that when the terminal locking member 2 is in the pre-locked position, the clearance holes 244 can accommodate the corresponding terminals without interfering with the insertion and removal of the terminals.

[0067] Optionally, at least two locking parts 24 are provided with a pre-locking component 2 between them and the housing 1, which can improve the connection stability and reliability between the terminal locking part 2 and the housing 1, and improve the uniformity of the force on the terminal locking part 2, which is beneficial to extending the service life of the terminal locking part 2.

[0068] In this embodiment, the locking part 24 has three parts: a first locking part 241 and two second locking parts 242. The two second locking parts 242 are respectively connected to the two ends of the first locking part 241 along a third direction, and the first locking part 241 and the second locking parts 242 are offset along a first direction, with the two second locking parts 242 in the same position in the first direction. That is to say, the terminal locking member 2 of this embodiment can lock two types of terminals, with the first locking part 241 and the second locking part 242 locking two types of terminals respectively.

[0069] Furthermore, a pre-locking component 2 is provided between the second locking part 242 and the housing 1.

[0070] Optionally, a pre-locking component is provided between the locking part 24 at both ends of the terminal locking member 2 along the third direction and the housing 1, thereby connecting both ends of the terminal locking member 2 along the third direction to the housing 1. This can improve the connection stability and reliability between the terminal locking member 2 and the housing 1, and improve the uniformity of the force on the terminal locking member 2, which is beneficial to extending the service life of the terminal locking member 2.

[0071] Optionally, the terminal locking member 2 is provided with a weight reduction structure 25, which can reduce the weight and material usage of the terminal locking member 2, thereby achieving lightweighting and reducing costs. For example, the weight reduction structure 25 includes weight reduction holes or weight reduction grooves, and the number of weight reduction holes or weight reduction grooves can be one, two, three, four, or even more, which is not limited here.

[0072] Optionally, the terminal locking member 2 also includes a force-applying part 26 for connection with the disassembly tool 100. The force-applying part 26 is exposed on the outside of the housing 1, so that when disassembling or switching the terminal locking member 2 from the final locking position to the pre-locking position, it is convenient to apply force to the force-applying part 26 by the disassembly tool 100, thereby improving the convenience of disassembly, assembly and use of the terminal locking member 2.

[0073] For example, the force-applying part 26 includes two force-applying protrusions, which are spaced apart. By having a disassembly tool 100, such as a pin-removing tool, abut against one side of the force-applying protrusion and apply force to lift the terminal locking member 2, the two force-applying protrusions repeat the same action, so that the terminal locking member 2 can be switched from the final locking position to the pre-locking position, or the terminal locking member 2 can be pulled out from the housing 1. Since there is no interference between the terminal locking member 2 and the cable of the terminal, the terminal can also be easily pulled out from the terminal socket 15 by the pin-removing tool. The terminal locking member 2 can also be reused.

[0074] Furthermore, the housing 1 is provided with a groove or through hole corresponding to the force-applying boss, so that the disassembly tool 100 can pass through the groove or through hole and abut against the force-applying boss.

[0075] It should be noted that when the connector is shipped, the terminal locking element 2 is already inserted into the locking socket 14 of the housing 1, and the terminal locking element 2 is in the pre-locked position. During customer application, simply insert the terminal into the corresponding terminal socket 15 on the housing 1, allowing the elastic clip of the terminal to engage with the positioning step on the housing 1 for initial locking. Since the terminal locking element 2 is in the pre-locked position at this time, simply pressing the terminal locking element 2 in the second direction will switch it from the pre-locked position to the final locked position, causing the terminal positioning structure 243 to abut against the corresponding terminal for secondary locking. This securely locks the terminal into the corresponding terminal socket 15, ensuring that the terminal will not loosen due to vibration or other external forces.

[0076] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
