Description

Technical Field

[0001] The utility model relates to a connector, in particular to a wiring female terminal structure and a connector. Background Art

[0002] The connector is connected by plugging the male end and the female end. The female end of some existing connectors has a clamping port, and the stress of metal deformation at the clamping port acts on the male terminal to achieve connection. However, such a metal clamping port can be easily deformed by accident during use, resulting in poor contact. In addition, some existing connectors are equipped with a metal sheet to hook the connector housing to prevent the terminal from falling out of the connector housing, but the metal sheet has a small holding force and is easy to withdraw.

[0003] Therefore, there is room for improvement in the terminals inside the connector. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] Reference below Figure 1-Figure 5 A female terminal structure 100 according to an embodiment of the present invention is described.

[0035] like Figure 1-Figure 4 As shown, according to some embodiments of the first aspect of the present utility model, the female terminal structure 100 comprises a plug-in tube 1. It is known that the plug-in tube 1 is used for plugging with the male terminal.

[0036] The plug-in tube 1 is formed by bending a plate, and the two opposite sides of the plate form a first side wall 12, and the two first side walls 12 are butted together to form a seam 13. The plug-in tube 1 surrounds a tube cavity 10 for installing the male end. That is, when the male end is placed in the tube cavity 10, the plug-in tube 1 forms a surrounding structure.

[0037] It is understandable that the connector will inevitably encounter impact, collision, and extrusion during operation, which requires the female terminal structure 100 to be well connected to the male terminal.

[0038] In some existing terminal connection structures, the plug-in portion for plugging into the male end usually includes two contacts, which are pressed toward each other to form a clamping force on the male end. At the same time, the elastic force of the two contacts will cause deformation, resulting in uneven pressure on the male end, which is easy to cause deformation due to accidental contact, causing poor contact of the connector.

[0039] The present application adopts a one-piece plate bent to form a plug-in tube 1, which has many advantages over the existing solutions:

[0040] 1. Simplify the production process: Bending the integrated plate to form the plug-in tube 1 can simplify the production process, reduce the assembly and welding processes of multiple components, and improve production efficiency.

[0041] 2. Increased reliability: The overall structural strength and stability of the plug-in tube 1 formed by bending the integrated plate are higher, and it can better withstand external impact, collision and extrusion, thereby improving the reliability and stability of the connection.

[0042] 3. Reduce costs: Bending the integrated plate to form the plug-in tube 1 can reduce the number of required parts, thereby reducing production costs.

[0043] 4. Improve contact reliability: The integrated plate is bent to form the plug-in tube 1, which can ensure that the male end is in the tube cavity 10 of the plug-in tube 1, improve the close contact between the female terminal structure 100 and the male end, reduce the risk of poor contact, and improve the reliability of the connection.

[0044] In this application, if Figure 1-Figure 2 As shown, the two opposite sides of the plate body constitute the first side wall 12, and the two first side walls 12 are butted together to form a joint 13. When the male end is inserted into the plug tube 1, the slight deformation and expansion of the joint 13 can provide sufficient clamping force to ensure that the male end remains stable in the plug tube 1. At the same time, since the slight deformation and expansion of the joint 13 is elastic deformation, it can return to its original shape when the male end is inserted or removed, ensuring the structural integrity of the plug tube 1.

[0045] This arrangement not only improves the stability of the male end connection, but also absorbs and disperses external forces when the plug tube 1 is deformed appropriately, reducing the force transmitted to the male end, effectively preventing the male end from shaking and displacing, and improving the stability and safety of the plug-in part.

[0046] Optionally, the cross section of the plug tube 1 perpendicular to its length direction is triangular, square, circular, etc. Cross sections of different shapes can adapt to different male ends. The cross-sectional size and shape of the plug tube 1 match the male end, so that the male end can smoothly enter and be stably fixed in the plug tube 1, avoiding the male end from shaking between the plug tubes 1, and providing a stable and reliable connection and support for the connector.

[0047] Specifically, Figure 1 As shown, the cross section of the plug tube 1 is square. In this way, the plug tube 1 includes four enclosing inner walls, which can limit the male end. When the connector is impacted, the inner walls can also disperse the impact force, so that the force acting on the unit area of ​​the internal male end is smaller. The plug tube 1 has an enclosing inner wall structure to support the internal male end, reducing the situation of shaking and poor contact caused by fewer male end connection points.

[0048] Thus, the square cross section of the plug tube 1 is not only easier to process, but also convenient for its installation and positioning with the connector housing, and avoids the misalignment of the plug tube 1 with the connector housing due to the rotation of the plug tube 1. For the convenience of description, the plug tube 1 is described as having a square cross section in this application.

[0049] Some existing connectors have a small piece of metal on the connector terminal to hook the connector housing to prevent it from falling out. However, this metal piece is easy to deform, causing the hook to flip, thereby causing the pin to fall out.

[0050] In order to solve the above problems, Figure 1 , Figure 3-Figure 4 As shown, the female terminal structure 100 in the present application further includes a fixing portion 2. The fixing portion 2 is mainly used to cooperate with the connector housing to maintain the connection between the connector housing and the terminal to prevent the terminal from falling out of the connector housing.

[0051] like Figure 1 As shown, the fixing part 2 is connected to the plug tube 1 and is located at at least one end of the joint 13. The fixing part 2 includes at least one pair of retaining walls 22, and the two retaining walls 22 in the same pair are each connected to a first side wall 12. The two retaining walls 22 protrude toward the side of the inner wall away from the plug tube 1, and cooperate with the connector housing to ensure that the female terminal structure 100 can be firmly held in place after being inserted into the connector and will not be easily withdrawn from the connector housing. This prevents the connection from loosening or falling off due to accidental collision or vibration, thereby improving the reliability of the entire connector.

[0052] like Figure 4 As shown, the retaining wall 22 has a lower edge 222 connected to the first side wall 12 and an upper edge 221 away from the first side wall 12. This arrangement enables the retaining wall 22 to form a stable connection with the first side wall 12. The connection of the lower edge 222 further strengthens the integrity of the retaining wall 22 and the first side wall 12, thereby improving the rigidity and stability of the female terminal structure 100.

[0053] like Figure 5 As shown, the distance L1 between the upper edges 221 of the two baffle walls 22 of the same pair is smaller than the distance L2 between the lower edges 222 of the two baffle walls 22 .

[0054] That is to say, the two retaining walls 22 of the same pair are in an inverted "V" shape. Among them, the distance between the upper edges 221 of the two retaining walls 22 of the same pair is small, which is convenient for stopping and preventing from falling off. The distance between the lower edges 222 of the two retaining walls 22 of the same pair is large to form a certain opening, so that it is convenient to insert something (such as a finger) here during adjustment, so that the wiring female end structure 100 can properly loosen the male end. After the adjustment is completed, the object (such as a finger) leaves the above-mentioned opening, and the wiring female end structure 100 returns to its original shape and can clamp the male end.

[0055] In addition, the two baffle walls 22 in the same pair can also provide support for each other. When one baffle wall 22 is deformed and leans against the other baffle wall 22, the other baffle wall 22 generates a reverse support force to it. Such mutual support can enhance the rigidity and stability of the baffle wall 22, reduce structural deformation caused by external forces, and reduce the possibility of needle withdrawal.

[0056] According to some embodiments of the present application, the female terminal structure 100 is as follows: Figure 5 As shown, the distance between the two blocking walls 22 in the same pair gradually decreases in the direction toward the upper edges 221 thereof.

[0057] After the female terminal structure 100 is connected to the male terminal, when entering the connector housing, the contact area between the two retaining walls 22 and the connector housing is small, making it easier for the terminal to be inserted into the connector housing. After the terminal enters the connector housing, the connector housing abuts against the rear side of the two retaining walls 22, and the distance between the two retaining walls 22 increases, thereby enhancing the grip between the connector housing and the terminal. The connection stability between the connector housing and the terminal can be improved accordingly. This arrangement helps to disperse the influence of external forces on the plug-in tube 1. When subjected to external shock or vibration, since the contact area of ​​the same pair of retaining walls 22 is larger, the external force can be more evenly dispersed between the connector housing and the retaining walls 22, reducing the possibility of stress concentration and further improving the stability and reliability of the plug-in tube 1.

[0058] According to some embodiments of the female terminal structure 100 of the present application, the dimension of the retaining wall 22 in the length direction of the joint 13 is the width of the retaining wall 22, and the width of the retaining wall 22 gradually decreases from the lower edge 222 to the upper edge 221. In this way, the lower edge 222 is wider, which ensures the root structural strength of the retaining wall 22 and reduces the risk of the retaining wall 22 being broken. The upper edge 22 is narrower, so that the opening between the two retaining walls 22 in the same pair forms an oblique opening, which is convenient for inserting something (such as a finger) into the oblique opening when opening.

[0059] like Figure 1 , Figure 3-Figure 4 As shown, according to some embodiments of the wiring female terminal structure 100 in the present application, the wiring female terminal further includes a cable connecting portion 3. The cable connecting portion 3 is arranged at one end of the plug tube 1. The cable connecting portion 3 is used to fix the wire harness.

[0060] like Figure 1 , Figure 3 As shown, the cable connecting portion 3 includes a first wire clamp 31 and a second wire clamp 33 .

[0061] like Figure 4As shown, the first wire clamp 31 includes a first wire clamp body 311 connected to the plug tube 1 and at least one first wire clamp arm 312 connected to the first wire clamp 31. This arrangement facilitates the installation and fixation of the wire harness, and the wire harness is quickly fixed by wrapping the first wire clamp arm 312 around the outer periphery of the wire harness.

[0062] In some embodiments, there are two first wire clamp arms 312, which are respectively located on both sides of the first wire clamp body 311. The wire harness is fixed in a cross-fixing manner, thereby ensuring that the wire harness can be effectively supported and fixed in all directions, and reducing the movement or vibration of the wire harness when subjected to external forces.

[0063] like Figure 4 As shown, in some embodiments, the second wire clamp 33 includes a second wire clamp body 331 connected to the first wire clamp body 311 and at least one second wire clamp arm 332 connected to the second wire clamp 33. The second wire clamp arm 332 is used to fix the wire harness.

[0064] In some embodiments, there are two second wire clamp arms 332, which are respectively located on both sides of the second wire clamp body 331. The two second wire clamp arms 332 are cross-fixed to fix the wire harness. In this way, the wire harness is effectively supported and fixed in all directions, and the movement or vibration of the wire harness when subjected to external force is reduced.

[0065] The second wire clamp body 331 is connected to a side of the first wire clamp body 311 away from the plug tube 1. The first wire clamp 31 and the second wire clamp 33 jointly fix the wire harness.

[0066] Alternatively, if Figure 1-Figure 3 As shown, at least one groove 313 is formed on the inner wall of the first wire clamp 31 , and the groove 313 passes through the first wire clamp body 311 and the first wire clamp arm 312 .

[0067] Specifically, the wire harness is arranged along the length direction of the first wire clamp body 311, and the groove 313 can increase the friction effect between the first wire clamp 31 and the connection surface of the wire harness. By increasing the friction force, the groove 313 ensures the stability of the wire harness in the first wire clamp 31 and reduces the displacement of the wire harness when subjected to external force.

[0068] In addition, the arrangement of the groove 313 also provides a certain buffer space for the wire harness, which allows the wire harness to have a certain buffer margin when subjected to external force, thereby reducing the possibility of stress concentration and improving the service life and reliability of the wire harness.

[0069] In some optional embodiments, the first wire clamp 31, the second wire clamp 33 and the plug tube 1 are formed by bending a plate body. In this way, on the one hand, the connection points between the first wire clamp 31, the second wire clamp 33 and the plug tube 1 can be reduced, and the connection points between two adjacent components can be reduced, thereby reducing the processing steps. In addition, the connected edges of two adjacent components pull each other, the integrity is stronger, and the overall structural strength can be greatly improved.

[0070] According to some embodiments of the present application, the female terminal structure 100 is as follows: Figure 1 As shown, the female terminal structure 100 further includes a processing sheet 4. The processing sheet 4 is connected to an end of the cable connecting portion 3 away from the plug tube 1.

[0071] The processing sheet 4 is used for processing operations. Firstly, after the processing sheet 4 is fixed, the plate body can be easily bent. Secondly, the processing sheet 4 is conducive to shearing.

[0072] In some embodiments, a processing hole 43 is provided on the processing sheet 4. The processing hole 43 is mainly used for positioning during processing to ensure the accuracy and consistency of processing operations such as bending or shearing. By using the processing hole 43, the operator can quickly and accurately position the plate, further improving production efficiency and accuracy.

[0073] According to the female terminal structure 100 of some embodiments of the present application, the processing sheet 4 includes two opposite first side edges 41 and two opposite second side edges 42 .

[0074] The second side edge 42 is connected to the first side edge 41 and is located on a side of the first side edge 41 away from the processing hole 43 .

[0075] In some embodiments, one first side 41 is connected to the cable connecting portion 3, and another first side 41 is provided with a positioning opening 411. The positioning opening 411 is used for positioning during processing, which helps to improve production accuracy.

[0076] At least one of the second side edges 42 is provided with a processing cutout 421. By providing the processing cutout 421, the strength is correspondingly reduced, and shearing is facilitated.

[0077] Specifically, adjacent female terminal structures 100 are connected through the processing sheet 4. When the processing cutout 421 is opened between adjacent female terminal structures 100, the connection strength of the adjacent female terminal structures 100 is reduced, making the shearing operation easier to perform. Optionally, the size and dimensions of the processing cutout 421 can be adjusted according to actual needs. The operator can select the appropriate position, size and number of the processing cutout 421 according to factors such as the thickness, material and shearing requirements of the female terminal structure 100.

[0078] like Figure 1-Figure 4As shown, according to some embodiments of the female terminal structure 100 of the present application, a mating opening 14 and an elastic arm 15 located in the mating opening 14 are formed by punching on at least one side wall of the plug tube 1, one end of the elastic arm 15 is connected to the edge of the mating opening 14, and a part of the elastic arm 15 is located in the tube cavity 10 of the plug tube 1. The elastic arm 15 is used to clamp the male end.

[0079] Specifically, the mating opening 14 and the elastic arm 15 located in the mating opening 14 are formed by punching on two opposite side walls of the plug tube 1. The two elastic arms 15 are opposite to each other, and the elastic arm 15 away from the edge of the mating opening 14 gradually approaches each other in the lumen 10 of the plug tube 1. When the male end enters the plug tube 1, the movement of the male end is effectively restricted.

[0080] The elastic arm 15 is located in the plug-in tube 1. During the processing, the surrounding structure of the plug-in tube 1 can prevent the elastic arm 15 from being deformed due to the influence of external forces.

[0081] Optionally, the elastic arm 15 includes a bending section. The bending section is formed at the connection portion of the elastic arm 15 away from the matching opening 14, and the elastic arm 15 is bent at the bending section and extends toward the outside of the lumen 10. In this way, a guide opening is formed between the two elastic arms 15. A guide is provided when the male end enters the lumen 10, thereby improving the connection efficiency.

[0082] According to some embodiments of the second aspect of the present invention, the connector includes the female terminal structure 100 in the embodiment of the first aspect of the present application. Since other components of the female terminal structure 100 according to the embodiment of the present invention, such as the connector, are known to ordinary technicians in the field, they will not be described in detail here.
