Description

Technical Field

[0001] The utility model relates to a conductive connection device, in particular to a crimping terminal and an electronic plug-in unit provided with the crimping terminal. Background Art

[0002] Conventional crimp terminals for assembling electronic parts generally include a terminal body and a punching hole provided throughout the terminal body. During production, a workpiece is processed to form the shape of the terminal body, and then a punching process is performed on the workpiece to form the punching hole, thereby weakening the structure. The punching hole makes the manufactured terminal body have a certain elasticity and can be inserted and locked in the corresponding crimping hole.

[0003] However, the existing crimping terminals use punching holes that penetrate the terminal body, which can easily make the terminal body insufficiently strong and too easy to deform and unable to maintain in the corresponding crimping hole. If punching is not used, and only a recess is formed on the surface of the terminal body by embossing to reduce the thickness of the terminal body, it may cause excessive resistance when plugging into the corresponding crimping hole, which may easily cause problems such as damage to the crimping hole or difficulty in inserting the terminal.

[0008] At least one indentation is concavely disposed in the middle section and is located on at least one of the bottom of the embossing concave portion and the second surface.

[0009] The utility model further proposes an electronic plug-in unit to solve the technical problem, which comprises:

[0010] a housing; and

[0030] In order to understand the technical features and practical effects of the utility model in detail and to realize the utility model according to the content, the preferred embodiment shown in the figure is further described in detail as follows:

[0031] like Figure 1 and Figure 2 As shown, the first preferred embodiment of the utility model provides a crimping terminal, which includes a terminal body 10, a stamped recess 20 and at least one indentation, wherein the stamped recess 20 and the indentation are formed on the terminal body 10 so that the crimping terminal can be inserted into a corresponding crimping hole and can be locked in the crimping hole.

[0032] like Figure 3 and Figure 4 As shown, the terminal body 10 is elongated and extends along an insertion direction D1, and the terminal body 10 includes two opposite surfaces and a connecting portion 11 and a crimping section 12 connected along the insertion direction D1. The end of the connecting portion 11 away from the crimping section 12 can form a fixed structure for the crimping terminal to be combined with the housing of an electronic plug-in by the fixed structure, or form a buffer structure to provide buffering capacity when the crimping terminal encounters resistance during insertion. There is no special limitation in the present invention, so the end of the connecting portion 11 is cut off in the figure. Figure 1 , Figure 2 and Figure 4 As shown, the two surfaces are respectively a first surface 101 and a second surface 102 , the crimping section 12 is located between the first surface 101 and the second surface 102 , and the crimping terminal can be plugged and combined with the crimping hole through the crimping section 12 .

[0033] like Figures 3 to 5 As shown, the stamped concave portion 20 is concavely disposed on the first surface 101 of the terminal body 10 and is formed on the crimping section 12. Figure 4 As shown, the embossed concave portion 20 forms a middle section 121 and two elastic deformation sections 122 in the crimping section 12. The middle section 121 is located between the bottom of the embossed concave portion 20 and the second surface 102. Figure 3 and Figure 4 As shown, the crimping terminal defines a width direction D2 that is orthogonal to the insertion direction D1. Figure 4 As shown, the middle section 121 has two opposite sides in the width direction D2 , and each of the elastic deformation portions 122 is correspondingly connected to one side of the middle section 121 .

[0034] like Figure 4 and Figure 5 As shown, the indentation is concavely arranged in the middle section 121 and is located on at least one of the bottom of the stamped concave portion 20 and the second surface 102. In the first preferred embodiment of the utility model, the crimping terminal includes an indentation, which is a surface indentation 30A, and the surface indentation 30A is located on the second surface 102. Through the arrangement of the surface indentation 30A, the structure of the terminal body 10 at the crimping section 12 can be weakened and have a certain elasticity, so that elastic deformation can be performed.

[0035] During specific production, a plate is used to process the crimping terminal, wherein the plate has two surfaces facing opposite directions. First, a punching process is performed to initially form the shape of the terminal body 10 on the plate, and then a coining process is performed to form the coined concave portion 20 on one surface of the plate (corresponding to the first surface 101). Finally, a knife mark forming process is performed on the other surface of the plate (corresponding to the second surface 102) to form the surface indentation 30A. Forming the coined concave portion 20 by coining can harden the surface of the plate, so that the terminal body 10 can be firmly maintained in the crimping hole later, and at the same time, the toughness and ductility can be retained deep inside the plate. The structure of the plate is weakened by combining with the surface indentation 30A to facilitate elastic deformation of the crimping section 12 of the terminal body 10.

[0036] In a preferred embodiment of the present invention, the first surface 101 and the second surface 102 are substantially parallel, and the substantially parallel includes that the first surface 101 and the second surface 102 are absolutely parallel, or slightly deviate from the absolute parallel by a small angle due to the error in the aforementioned processing of the plate; the aforementioned crimping section 12 is located between the first surface 101 and the second surface 102, which means that the structure of the crimping section 12 does not exceed the parallel first surface 101 and the second surface 102, but can cover the first surface 101 and the second surface 102.

[0037] In addition, during the above-mentioned stamping process, the material is pushed outward from the stamping recess 20 and the surface indentation 30A due to the force applied to the material, causing the shape of the sheet to expand outward. Therefore, after the stamping recess 20 and the surface indentation 30A are formed, a second punching and shearing process can be performed to trim the expanded portion of the sheet so that the sheet can once again form the predetermined shape of the terminal body 10. Through the above steps, the size of the crimping terminal can be accurately controlled.

[0038] like Figure 6 As shown, the produced crimping terminal is used to be plugged into a crimping hole 91 to achieve the connection effect of electrical signals and structures. Specifically, the crimping hole 91 can be located on a printed circuit board (PCB), but is not limited to this. First, the terminal body 10 is inserted into the crimping hole 91 along the insertion direction D1. Since the indentation weakens the structure at the crimping section 12 and makes it elastic, the crimping section 12 can be elastically deformed when it is subjected to the resistance of the crimping hole 91, so as to be inserted into the crimping hole 91.

[0039] like Figure 4 As shown, since the embossed concave portion 20 is concavely disposed on the first surface 101, when subjected to the resistance of the crimping hole 91, the two elastic deformation portions 122 tend to deflect toward the first surface 101 in a direction close to each other, and the surface indentation 30A concavely disposed on the middle section 121 weakens the structure of the crimping section 12, so that the crimping section 12 can be elastically deformed smoothly, as shown in FIG. Figure 7 As shown, during deformation, the two elastic deformation portions 122 located at the first surface 101 deflect toward a direction approaching each other until the crimping section 12 is stuck in the crimping hole 91 .

[0040] According to the above, the present invention enables different positions of the crimping section 12 to have different degrees of deformation through the embossed recess 20, and the embossing recess is arranged at the middle section 121 of the crimping section 12 to weaken the structure of the crimping section 12, so that the crimping section 12 can be elastically deformed in a swinging manner so as to be plugged into the crimping hole 91, thereby avoiding excessive resistance during plugging, which may cause damage to the crimping hole 91 or difficulty in insertion, and the middle section 121 and the two elastic deformation portions 122 of the crimping section 12 are still connected as a whole, maintaining a non-through design and having sufficient structural strength, and can be firmly maintained in the crimping hole 91 after plugging, and compared with the existing crimping terminals using punching holes, the crimping section 12 can be prevented from loosening from the crimping hole 91; thereby, the present invention provides a crimping terminal that is suitable for production, is easy to insert into the corresponding crimping hole, and can be stably clamped in the crimping hole.

[0041] Further, if Figure 4 As shown, the middle section 121 has a thickness t, and the thickness t is defined as the distance between the bottom of the stamped recess 20 and the second surface 102 of the terminal body 10. The surface indentation 30A is recessed in the middle section 121 on the second surface 102 and has a depth d1, and the depth d1 is less than or equal to half of the thickness t (d1≤t / 2). By having the surface indentation 30A with an appropriate depth d1, the structure of the crimping section 12 can be appropriately weakened to prevent the surface indentation 30A from penetrating the terminal body 10; for example, if the depth d1 is greater than half of the thickness t, the surface indentation 30A may form a structure that penetrates the terminal body 10. The design in which the depth d1 is less than or equal to half of the thickness t can prevent the formation of the penetrating structure and avoid the risk of excessive weakening of the structure of the terminal body 10 and material damage, thereby ensuring that the crimping terminal can be clamped in the crimping hole 91.

[0042] In addition, the specific value of the depth d1 of the surface indentation 30A can be designed according to needs. When the depth d1 of the surface indentation 30A is designed to be deeper, the crimping section 12 has better elasticity and less resistance when inserted into the crimping hole 91; conversely, if the depth d1 of the surface indentation 30A is designed to be shallower, the crimping section 12 has stronger structural strength and rigidity, and the retention force of the crimping section 12 in the crimping hole 91 is greater.

[0043] Going further, Figure 4 As shown, the cross section of the surface indentation 30A is V-shaped and has an angle θ1. Specifically, the surface indentation 30A has a width W1. The relationship between the width W1, the angle θ1 and the depth d1 satisfies the following relationship:

[0044]

[0045] Among them, the angle θ1 is between 45° and 120°, including the endpoint value (45°≤θ1≤120°). By having the surface indentation 30A with an appropriate angle θ1, the surface indentation 30A is suitable for processing, which can avoid the angle θ1 being too small to affect the strength and service life of the punch for processing the surface indentation 30A, and can also avoid the problem of excessive weakening of the structure of the crimping section 12 due to the angle θ1 of the surface indentation 30A being too large.

[0046] Preferably, if Figure 5 As shown, the embossed concave portion 20 gradually shrinks from the first surface 101 toward the second surface 102, so that the top of the embossed concave portion 20 and the bottom of the embossed concave portion 20 have a first length C1 and a second length C2 respectively in the insertion direction D1, and the surface indentation 30A located on the second surface 102 has a length a along the insertion direction D1, wherein the length a of the surface indentation 30A is between the first length C1 and the second length C2, including the endpoint value (C2≤a≤C1). The surface indentation 30A has the effect of weakening the strength of the terminal structure to achieve better elastic deformation, and the length a of the surface indentation 30A is between the first length C1 and the second length C2, which can effectively achieve the effect of weakening without causing the structure to be too fragile. If the length a of the surface indentation 30A is smaller than the second length C2 of the stamped recess 20, the elastic amplitude of the deformable portion may be ineffective due to the small size of the surface indentation 30A; if the length a of the surface indentation 30A is larger than the first length C1 of the stamped recess 20, the structure may be too fragile and the terminal may be at risk of being damaged along the deformation direction.

[0047] In addition, the specific value of the length a of the surface indentation 30A can be designed according to needs. If better elasticity is required, the length a of the surface indentation 30A can be designed to be longer. If more sufficient maintaining force is required to be clamped in the crimping hole 91, the length a of the surface indentation 30A can be designed to be shorter.

[0048] like Figure 8 As shown, the first preferred embodiment of the utility model further provides an electronic plug-in, which includes a shell 90 and a plurality of crimping terminals 80 as described above, and the plurality of crimping terminals 80 are arranged on the shell 90 at intervals, wherein the electronic plug-in can be a press-fit connector, such as a wire-to-board connector (WTB connector), a board-to-board connector (BTB connector), a row of pins (pin header), but is not limited to the above; through the plurality of crimping terminals 80, the electronic plug-in can have the effect of being suitable for production as described above, and can be firmly plugged into the crimping hole by the crimping terminals 80.

[0049] See also Figures 9 to 11 As shown, the crimping terminal provided by the second preferred embodiment of the present invention is different from the first preferred embodiment of the present invention in that the indentation is a concave indentation 30B, and the concave indentation 30B is located on the bottom of the embossed concave portion 20. By recessing the concave indentation 30B in the middle section 121, the effect of weakening the structure of the crimping section 12 can be achieved, as in the surface indentation 30A of the first preferred embodiment of the present invention. Fig.13 and Fig.14 As shown, when the crimping terminal is inserted into the crimping hole 91, the crimping section 12 can also be elastically deformed in the form of a swing so as to be inserted into the crimping hole 91, and the crimping section 12 can also be firmly maintained in the crimping hole 91 after insertion, and the problem of the existing crimping terminal causing damage to the punch or the terminal body 10 due to the punching size, or being unable to be stably maintained in the crimping hole can also be avoided.

[0050] Further, if Fig.11 As shown, the recessed indentation 30B is recessed in the middle section 121 and has a depth d2, and the depth d2 is less than or equal to half of the thickness t of the middle section 121 (d2≤t / 2). By having the recessed indentation 30B with an appropriate depth d2, the structure of the crimping section 12 can be appropriately weakened and prevented from penetrating the terminal body 10, just like the surface indentation 30A of the first preferred embodiment of the utility model, avoiding excessive weakening of the structure of the terminal body 10 and the risk of material damage, thereby ensuring that the crimping terminal can be firmly clamped in the crimping hole 91.

[0051] In addition, the specific value of the depth d2 of the recessed indentation 30B can also be designed according to demand. When the depth d2 of the recessed indentation 30B is designed to be deeper, the crimping section 12 has better elasticity and less resistance when inserted into the crimping hole 91. Conversely, the retaining force of the crimping section 12 in the crimping hole 91 is greater.

[0052] Going further, Fig.11 As shown, the cross section of the concave indentation 30B is V-shaped and has an angle θ2. Specifically, the concave indentation 30B has a width W2. The relationship between the width W2, the angle θ2 and the depth d2 satisfies the following relationship:

[0053]

[0054] Among them, the angle θ2 is between 45° and 120°, including the endpoint value (45°≤θ1≤120°). By having the concave indentation 30B with an appropriate angle θ2, the strength and service life of the processed punch can be ensured, and the problem of the concave indentation 30B being difficult to process and the structure of the crimping section 12 being excessively weakened can be avoided, just like the surface indentation 30A of the first preferred embodiment of the utility model mentioned above.

[0055] Preferably, if Fig.12 As shown, the recessed indentation 30B located on the bottom of the embossed recessed portion 20 has a length b along the insertion direction D1, wherein the length b of the recessed indentation 30B is less than or equal to the second length C2 (b≤C2) of the aforementioned embossed recessed portion 20, thereby avoiding the processing range of the recessed indentation 30B exceeding the embossed recessed portion 20, thereby ensuring that the recessed indentation 30B is easier to process and form.

[0056] In addition, the specific value of the length b of the recessed indentation 30B can be designed according to demand. By having the recessed indentation 30B have an appropriate length b, the elasticity and structural strength of the crimping section 12 can be adjusted to reduce the resistance of the crimping section 12 to deformation along the hole wall of the crimping hole 91 when the crimping section 12 is inserted into the crimping hole 91, or to adjust the maintaining force after the crimping section 12 is inserted into the crimping hole 91.

[0057] The first and second preferred embodiments of the present invention respectively use the surface indentation 30A and the recessed indentation 30B, wherein the surface indentation 30A is located on the second surface 102 of the terminal body 10 and is easier to process than the recessed indentation 30B. Fig.11 and Fig.12 As shown, in the second preferred embodiment of the utility model, the crimping section 12 forms a plane 13 at the bottom of the stamping recess 20. Therefore, in the specific production process, after the stamping recess 20 is formed by stamping, when it is desired to continue to form the recess indentation 30B, a knife mark forming process is further performed on the aforementioned plane 13, which can reduce the processing difficulty of the recess indentation 30B, thereby avoiding an increase in production costs.

[0058] In addition, if Figure 7 As shown, the first preferred embodiment of the utility model adopts the surface indentation 30A located on the second surface 102, which can make the two elastic deformation parts 122 of the crimping section 12 located on the first surface 101 more easily deflected in the direction of approaching each other, generating elastic deformation, which can improve the convenience of inserting the crimping terminal into the crimping hole 91; and as shown Fig.14As shown, the second preferred embodiment of the utility model adopts a concave indentation 30B located at the bottom of the stamped concave portion 20, and the two elastic deformation portions 122 of the crimping section 12 are swung in a direction close to each other. After elastic deformation, the two sides of the concave indentation 30B can approach each other and resist each other, thereby generating a stopping force to prevent the crimping section 12 from excessive deformation.

[0059] See also Fig.15 and Fig.16 As shown, the crimping terminal provided in the third preferred embodiment of the present invention is different from the first and second preferred embodiments of the present invention in that the crimping terminal has two indentations, which are the surface indentation 30A and the concave indentation 30B. Fig.17 As shown, when the crimping terminal is inserted into the crimping hole 91, the crimping section 12 can also be elastically deformed in the form of deflection so as to be inserted into the crimping hole 91, and the crimping section 12 can also be firmly maintained in the crimping hole 91 after insertion, and the existing crimping terminal can also avoid the problem of damage to the punch or the terminal body 10 due to the punching size, or the problem of being unable to be stably maintained in the crimping hole. Among them, the sum of the depth d1 and the depth d2 of the surface indentation 30A and the concave indentation 30B is less than or equal to half of the thickness t of the middle section 121, so that the structure of the crimping section 12 is appropriately weakened, and at the same time, the material of the terminal body 10 is prevented from being damaged.

[0060] Looking at the above three preferred embodiments, as long as the sum of the depths of the indentations is less than or equal to half of the thickness t of the middle section 121, for example, for the first and second preferred embodiments of the utility model including a single indentation, the depth d1 of the surface indentation 30A or the depth d2 of the recessed indentation 30B is respectively the sum of the depths of the indentations, and for the third preferred embodiment of the utility model including two indentations, the sum of the depth d1 of the surface indentation 30A and the depth d2 of the recessed indentation 30B is the sum of the depths of the indentations, the above-mentioned effect of appropriately weakening the structure of the crimping section 12 can be achieved, thereby avoiding damage to the material of the terminal body 10 during crimping and ensuring that the crimping terminal can be clamped in the crimping hole 91.

[0061] In addition, the third preferred embodiment of the utility model includes the surface indentation 30A and the recessed indentation 30B, which can simultaneously have the effect of improving the convenience of inserting the crimping terminal into the crimping hole 91 as described above in the first preferred embodiment of the utility model, and preventing the crimping section 12 from excessive deformation as described above in the second preferred embodiment of the utility model.

[0062] The above description is only a preferred embodiment of the utility model and does not limit the utility model in any form. Any person with ordinary knowledge in the technical field can make equivalent embodiments by partial changes or modifications to the technical content disclosed in the utility model without departing from the scope of the technical solution of the utility model, and they still fall within the scope of the technical solution of the utility model without departing from the technical solution of the utility model.
