Description

Technical Field

[0001] This utility model relates to the field of electrical connection technology, and in particular to an open fisheye terminal structure. Background Technology

[0002] With the rapid development of electronic information technology, connectors are needed to interconnect actuators to exchange current or signals in order to complete the predetermined functions of the circuit. Existing connection methods for conducting signals are generally divided into two types: soldered connections and solderless connections. Solderless connection technology is undoubtedly one of the fastest and most convenient methods. Solderless connections also have a positive impact on reducing environmental pollution and lowering raw material costs.

[0003] The most widely used solderless connection method is the plug-in terminal. This connection method reduces flux usage, avoids adverse reactions when the PCB (Printed Circuit Board) is exposed to high-temperature solder pots, and allows for easy removal and replacement. Furthermore, because there are no solder joint issues such as open circuits, its electrical reliability is also high. Among plug-in terminals, the fisheye terminal is the most typical. A fisheye terminal consists of a base, two elastic parts connected to the base, and pins connected to the two elastic parts. The elastic parts are arc-shaped, and the two elastic parts face each other, forming a fisheye hole between them. During assembly, the elastic parts are compressed and elastically contract, allowing the fisheye terminal to be smoothly inserted into the through-hole of the circuit board, thus achieving electrical connection between the fisheye terminal and the PCB board.

[0004] In the prior art, after the fisheye terminal is inserted, because its fisheye hole is closed, its elastic part is not easy to elastically contract when squeezed. The terminal is also not easy to come out of the conductive socket after insertion, which can ensure that the fisheye terminal and the PCB board form a reliable electrical connection. However, the terminal is relatively difficult to insert and is easy to damage the circuit board. In addition, the fisheye terminal is also prone to breakage due to excessive stress during the assembly process.

[0005] Therefore, a new technology needs to be developed to solve the above problems. Utility Model Content

[0006] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide an open fisheye terminal structure, which forms an open design of fisheye-shaped terminals, which can take into account the performance of more appropriate insertion force and better tightness, and is not easy to damage the circuit board, and can avoid the terminal breakage caused by excessive stress.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An open-type fisheye terminal structure includes a base, a connecting portion, and a plug-in portion connected in sequence; the base extends laterally, and the connecting portion extends vertically; the plug-in portion includes a first elastic portion, a second elastic portion, and a reinforcing portion, one side of the reinforcing portion is connected to the end of the connecting portion away from the base, the first elastic portion and the second elastic portion are both connected to the other side of the reinforcing portion, and a fisheye hole is formed between the first elastic portion and the second elastic portion; there is a gap between the end of the first elastic portion away from the reinforcing portion and the end of the second elastic portion away from the reinforcing portion, and the gap communicates with the fisheye hole.

[0009] As a preferred embodiment, the connecting portion has through holes extending through both sides in the thickness direction of the connecting portion.

[0010] As a preferred embodiment, both side walls of the connecting portion in the width direction are provided with protrusions.

[0011] As a preferred embodiment, the end of the connecting portion near the base is connected to an arc-shaped portion, and the end of the base near the connecting portion is connected to the end of the arc-shaped portion away from the connecting portion.

[0012] As a preferred embodiment, the base is rectangular, the width of the arcuate portion is smaller than the width of the connecting portion, and the width of the connecting portion is smaller than the width of the base.

[0013] As a preferred embodiment, both the first elastic portion and the second elastic portion have an arc-shaped structure, and the first elastic portion and the second elastic portion are symmetrically arranged.

[0014] As a preferred embodiment, the reinforcing part has arc-shaped transition grooves recessed on both sides in the width direction.

[0015] As a preferred embodiment, the end face of the first elastic part away from the reinforcing part and the end face of the second elastic part away from the reinforcing part are both first flat surfaces that extend laterally.

[0016] As a preferred embodiment, the surface of the first elastic part away from the reinforcing part facing the gap and the surface of the second elastic part away from the reinforcing part facing the gap are both vertically extending second flat surfaces.

[0017] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, it mainly involves making the terminal include a base, a connecting part, and a plug-in part connected in sequence. The plug-in part includes a first elastic part, a second elastic part, and a reinforcing part. A fisheye hole is formed between the first elastic part and the second elastic part. There is a gap between the end of the first elastic part away from the reinforcing part and the end of the second elastic part away from the reinforcing part. The gap is connected to the fisheye hole. In this way, an end break can be formed, thereby forming an open design of the fisheye terminal. This design can take into account the performance of more suitable insertion force and better tightness, and is less likely to damage the circuit board. It also allows the first elastic part and the second elastic part to undergo elastic deformation easily, avoiding excessive stress that could cause the terminal to break.

[0034] Please refer to Figures 1 to 5 As shown, it illustrates the specific structure of the open fisheye terminal structure provided in an embodiment of the present invention.

[0035] The open fisheye terminal structure includes a base 10, a connecting part 20 and a plug-in part 30 connected in sequence; the plug-in part 30 is used to insert into a through hole of a circuit board, the base 10 extends laterally and the connecting part 20 extends vertically.

[0036] The connecting part 20 has through holes 21 extending through both sides in the thickness direction of the connecting part 20, so that the design of the through holes 21 can enhance the assembly firmness between the terminal and the external structure; both sides of the connecting part 20 in the width direction are provided with protrusions 22, so that the assembly firmness between the terminal and the external structure can be further enhanced by the protrusions 22.

[0037] The connecting portion 20 is integrally connected to an arc-shaped portion 40 at one end near the base 10. The base 10 is integrally connected to the arc-shaped portion 40 at one end away from the connecting portion 20. The connecting portion 20, the arc-shaped portion 40, and the base 10 maintain a smooth transition, so that the connection between the connecting portion 20 and the base 10 is smoother through the arc-shaped portion 40. The base 10 is rectangular, and the width of the arc-shaped portion 40 is smaller than the width of the connecting portion 20, and the width of the connecting portion 20 is smaller than the width of the base 10.

[0038] Both the first elastic part 31 and the second elastic part 32 have an arc-shaped structure. The first elastic part 31 and the second elastic part 32 are symmetrically arranged. Both sides of the reinforcing part 33 in the width direction are recessed with arc-shaped transition grooves 36.

[0039] The insertion portion 30 includes a first elastic portion 31, a second elastic portion 32, and a reinforcing portion 33. One side of the reinforcing portion 33 is integrally connected to the end of the connecting portion 20 away from the base 10. The first elastic portion 31 and the second elastic portion 32 are integrally connected to the other side of the reinforcing portion 33. A fisheye hole 34 is formed between the first elastic portion 31 and the second elastic portion 32. There is a gap 35 between the end of the first elastic portion 31 away from the reinforcing portion 33 and the end of the second elastic portion 32 away from the reinforcing portion 33, and they can undergo elastic deformation under compression and move closer to each other. The gap 35 communicates with the fisheye hole 34. After the insertion portion 30 of the terminal is inserted into the through hole of the circuit board, the first elastic portion 31 and the second elastic portion 32 undergo elastic deformation under the pressure and move closer to each other to close the gap 35. Here, by providing a gap 35 between the ends of the first elastic portion 31 and the second elastic portion 32, an end break can be formed, thereby forming an open design of the fisheye-shaped terminal. This design can take into account the performance of more suitable insertion force and better tightness, and is less likely to damage the circuit board. It also allows the first elastic portion 31 and the second elastic portion 32 to undergo elastic deformation easily, avoiding excessive stress that could cause the terminal to break.

[0040] The end face of the first elastic part 31 away from the reinforcing part 33 and the end face of the second elastic part 32 away from the reinforcing part 33 are both horizontally extending first flat surfaces 37; the surface of the first elastic part 31 away from the reinforcing part 33 facing the gap 35 and the surface of the second elastic part 32 away from the reinforcing part 33 facing the gap 35 are both vertically extending second flat surfaces 38, so as to facilitate the closing of the gap 35; the second flat surface 38 is in contact with the first flat surface 37 and is perpendicular to each other.

[0041] like Figure 5 The diagram shows a general manufacturing process of the open fisheye terminal structure. The general manufacturing process is as follows: First, the plug-in part 30 and part of the connecting part 20 are stamped on the material plate 50. Then, the entire connecting part 20 and the base 10 are stamped. Finally, the part is bent to form an arc-shaped part 40.

[0042] In summary, the key design feature of this utility model lies in its use of a terminal comprising a base, a connecting portion, and a plug-in portion connected in sequence. The plug-in portion includes a first elastic portion, a second elastic portion, and a reinforcing portion. A fisheye hole is formed between the first elastic portion and the second elastic portion, and a gap exists between the end of the first elastic portion away from the reinforcing portion and the end of the second elastic portion away from the reinforcing portion, with the gap connected to the fisheye hole. This allows for the formation of an end break, resulting in an open design for the fisheye-shaped terminal. This design balances more suitable insertion force and better fit, while minimizing damage to the circuit board. It also allows the first and second elastic portions to easily undergo elastic deformation, preventing excessive stress from causing terminal breakage.

[0043] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
