Description

Technical Field

[0001] The invention relates to the technical field of electrical connection components, and in particular to a heightened circuit board connector. Background Art

[0002] In the prior art, most electrical connection terminals have one end that is crimped and fixed to a wire, and the other end that is plugged into another pin or connection structure for electrical conduction to achieve transmission of electrical signals. Among them, there is also a connector that is connected to a circuit board, which is used to connect wires to a PCB board. After the terminal is crimped to the wire, it is installed on a PCB board with a suitable aperture to achieve automatic welding.

[0003] However, in the automated soldering process, due to the low height of the electrical connection terminals, the rubber of the wires melts during the wave soldering process at 260°C for 3 seconds, resulting in poor quality. At the same time, after the electrical connection terminals are installed in the holes of the PCB board, the barbed structure is generally long and the electrical connection terminals are prone to tilting without straightening, which affects the subsequent processing and yield rate.

[0004] Therefore, how to provide a heightened circuit board connector to solve the problems of melt glue and tilting during welding in the prior art is a technical problem that needs to be solved urgently by those skilled in the art. Summary of the invention

[0005] To this end, the present invention provides a heightened circuit board connector to solve the related technical problems existing in the prior art.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0007] A heightened circuit board connector comprises: a terminal body arranged in a long strip shape; a first crimping portion arranged at the front end of the terminal body and used to wrap a stripped metal wire; a second crimping portion arranged at the rear end of the terminal body and used to wrap a wire sheath; and a heightened portion arranged between the front end and the rear end of the terminal body, and a heightened crimping portion is arranged on the heightened portion.

[0008] Furthermore, the second crimping portion includes a second wing plate symmetrically formed on both sides of the terminal body and a wrapping isolation plate at the lower end of the second wing plate, the wrapping isolation plate is integrally formed with the second wing plate through arc bending, the wrapping isolation plate is bent toward the terminal body, and the wrapping isolation plate is against the stripped end of the wrapping wire skin.

[0009] Furthermore, it also includes a curved groove arranged along the length direction of the wrapping isolation plate, and at least one curved groove is arranged on the wrapping isolation plate.

[0010] Further, the high-voltage connection part includes third wing plates symmetrically formed on both sides of the terminal body.

[0011] Further, the first crimping part includes first wing plates symmetrically formed on both sides of the terminal body. A limiting part bent outward is provided at the upper end of the first wing plate, and barbs bent outward and cooperating with the limiting part are provided in the middle of the first wing plate.

[0012] Further, a first slit is opened on one side of the limiting part, and the first slit is arranged from the upper end to the lower end of the first wing plate.

[0013] Further, the first slits on the two first wing plates are arranged on the same side or on different sides.

[0014] Further, second slits are opened on both sides of the limiting part, and the second slits are arranged from the upper end to the lower end of the first wing plate.

[0015] Further, the lengths of the second slits arranged on both sides of the limiting part are the same or different, and the second slits on the two first wing plates are mirror-symmetric or centrosymmetric.

[0016] Further, the connection part between the lower part of the limiting part and the first wing plate is a bending part.

[0017] The present invention has the following advantages:

[0018] By providing a heightening part and a wrapping isolation plate in the middle of the terminal body, on the one hand, the distance between the welding position and the wire skin is increased, and on the other hand, the end part of the peeled wire skin is shielded and protected, thus effectively preventing the problem of poor quality caused by the melting of the rubber skin. At the same time, the lengthened peeled metal wire is effectively wrapped and clamped, improving the electrical connection effect; at the same time, a first slit or a second slit is provided on the limiting part, and a bending part is correspondingly provided at the lower end of the limiting part, so as to improve the cooperation effect with the barb, keep the terminal body vertical after being inserted into the PCB board, and prevent the problem that the inclination of the terminal body after welding affects subsequent processing and the reduction of the yield rate.

Specific embodiments

[0038] The following specific embodiments illustrate the implementation manners of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] In order to solve the problems existing in the prior art that during the automatic soldering process, due to the low height of the electrical connection terminal, the rubber skin of the wire melts during the 3-second process at 260°C in wave soldering, resulting in poor quality. At the same time, after the electrical connection terminal is inserted into the PCB board hole, due to the generally long barb structure design, the electrical connection terminal is prone to tilt without being straightened, affecting the subsequent processing process and the yield rate. Based on the use defects of the existing structure, the applicant proposed a heightening type circuit board connector, mainly by setting a heightening part and a wrapping isolation plate in the middle of the terminal body. On the one hand, the distance between the soldering position and the wire skin is increased, and on the other hand, the peeled end of the wire skin is shielded and protected, thus effectively preventing the problem of poor quality caused by the melting of the rubber skin. At the same time, it also effectively wraps and clamps the lengthened peeled metal wire, improving the electrical connection effect.

[0040] Embodiment 1

[0041] This embodiment provides a heightening type circuit board connector, as Figure 1-3 shown, including:

[0042] The terminal body 1 is arranged in a long strip shape;

[0043] The first crimping portion 2 is disposed at the front end of the terminal body 1 and is integrally formed with the terminal body 1 for wrapping the stripped metal wire, establishing an electrical connection relationship between the terminal body 1 and the metal wire, and preventing the metal wire from being pulled out of the terminal body 1;

[0044] The second crimping portion 3 is disposed at the rear end of the terminal body 1 for wrapping the wire insulation, thereby isolating the wire insulation to a certain extent and preventing the wire insulation from melting due to the high temperature during soldering; and

[0045] The heightening portion 4 is disposed between the front end and the rear end of the terminal body 1, and a high-pressure crimping portion 5 is disposed on the heightening portion 4. As Figure 2 shown, the high-pressure crimping portion 5 includes third wing plates 501 symmetrically formed on both sides of the terminal body 1. As Figure 4 shown, the metal wire is crimped on the heightening portion 4 area, thereby effectively preventing the problem of looseness of the metal wire after heightening and stripping.

[0046] As Figure 5 shown, the first crimping portion 2 is inserted into the insertion hole of the PCB board, and the first crimping portion 2 and the PCB board are in a snap connection relationship, and the stable electrical connection relationship between the two is further achieved through the soldering process.

[0047] Embodiment 2

[0048] Based on the above main structure, in this embodiment, the second crimping portion 3 includes second wing plates 301 symmetrically formed on both sides of the terminal body 1 and a wrapping isolation plate 302 at the lower end of the second wing plates 301. The wrapping isolation plate 302 is integrally formed with the second wing plates 301 through an arc-shaped bend. The wrapping isolation plate 302 is bent towards the terminal body 1 and the wrapping isolation plate 302 abuts against the stripped end of the wire insulation. Therefore, during use, the wire passes through the end of the second wing plate 301 of the terminal body 1, and the stripped metal wire continues to pass downward through the heightening portion 4 and the first crimping portion 2 in sequence. The metal wire is wrapped, fixedly connected by the high-pressure crimping portion 5 on the heightening portion 4 and fixedly connected by the first crimping portion 2, while the stripped end of the wire insulation stays in the area of the second wing plate 301, and the end of the wire insulation abuts against the wrapping isolation plate 302. During the crimping process, the second wing plate 301 wraps the upper part of the wire insulation, while the wrapping isolation plate 302 wraps the stripped end of the wire insulation. Through the above structure, the end area of the wire insulation can be blocked during the soldering process, avoiding the wire insulation from melting due to high temperature.

[0049] Embodiment 3

[0050] Through the structure of Embodiment 2, it is already possible to shield the end of the wire skin peeling by wrapping the isolation plate 302, thereby preventing high-temperature molten glue. However, during the wire pressing process, the inner side of the wrapping isolation plate 302 needs to be bent, and it is easy for the middle part of the wrapping isolation plate 302 to be distorted, resulting in incomplete wrapping of the end of the wire skin peeling and affecting the isolation effect. Therefore, on the basis of the above Embodiment 2, it further includes a bending groove 303 arranged along the length direction of the wrapping isolation plate 302. As Figure 6-7 shown, at least one bending groove 303 is provided on the wrapping isolation plate 302. During the crimping process, due to the setting of the bending groove 303, it can provide a space for the bending process, thereby ensuring that the wrapping isolation plate 302 is bent normally to wrap the wire skin without void areas, enhancing the isolation effect.

[0051] Embodiment 4

[0052] As Figure 1-7 shown in, in Embodiments 1-3, when the first crimping portion 2 is inserted and fixed to the PCB board, the barb 203 structure and the limiting structure are arranged on the same side and in the same direction. When the jack of the PCB board is large or the distance between the barb 203 mechanism and the limiting structure is far and the PCB board cannot be clamped, the PCB board will be in an inclined state, so that during the welding process and subsequent processing process, the terminal body 1 will affect the subsequent processing and the yield.

[0053] In this embodiment, to solve the above technical problems, the first crimping portion 2 includes first wing plates 201 symmetrically formed on both sides of the terminal body 1. The upper ends of the first wing plates 201 are provided with limiting members 202 bent outward, and the middle parts of the first wing plates 201 are provided with barbs 203 bent outward and cooperating with the limiting members 202, so that the PCB board is clamped between the barbs 203 and the limiting members 202. Specifically, in this embodiment, it further includes a first slit 6 opened on one side of the limiting member 202. The first slit 6 is arranged from the upper end to the lower end of the first wing plate 201. As Figure 8-10 shown, one first slit 6 is arranged on the side of the limiting member 202. Through this first slit 6, it can make the first crimping portion 2 deflect during the crimping process of the metal wire, especially the upper part of the limiting member 202 deflect backward or forward, so that the projections of the limiting member 202 and the barb 203 are not on the same straight line, that is, the limiting member 202 deflects relative to the barb 203, and the contact positions of the limiting member 202 and the barb 203 are different, which can make the terminal body 1 keep upright without tilting.

[0054] On the above basis, in order to improve the fixing effect between the PCB board and the first crimping portion 2, this application proposes two setting methods:

[0055] One way is that the first slits 6 on the two first wing plates 201 are on the same side, that is, the two first slits 6 are symmetrically arranged. When the first slit 6 is arranged on the front side of the limiting member 202, after crimping, the limiting member 202 deflects towards the rear side of the terminal body 1, so that the orientation is different from that of the barb 203; when the first slit 6 is arranged on the rear side of the limiting member 202, after crimping, the limiting member 202 deflects towards the front side of the terminal body 1, so that the orientation is different from that of the barb 203.

[0056] Another way is that the first slits 6 on the two first wing plates 201 are on different sides, that is, the two first slits 6 are arranged at different positions. One of the first slits 6 is arranged on the front side of the limiting member 202, and the other first slit 6 is arranged on the rear side of the limiting member 202. After crimping, one limiting member 202 deflects towards the rear side of the terminal body 1, and the other limiting member 202 deflects towards the front side of the terminal body 1, so that the orientation is different from that of the barb 203.

[0057] Embodiment 5

[0058] As Figure 1-7 shown, in Embodiments 1-3, when the first crimping portion 2 is inserted and fixed to the PCB board, the barb 203 structure and the limiting structure are arranged on the same side and in the same direction. When the insertion hole of the PCB board is relatively large or the distance between the barb 203 mechanism and the limiting structure is relatively far and the PCB board cannot be clamped, the PCB board will be in an inclined state, so that during the welding process and subsequent processing process, the terminal body 1 will affect the subsequent processing and the yield rate.

[0059] The principle applied in Embodiment 4 is the same, but the structure is different. Specifically, as Figure 11-14 shown, it further includes second slits 7 opened on both side portions of the limiting member 202. The second slits 7 are arranged from the upper end to the lower end of the first wing plate 201, that is, two second slits 7 are arranged, respectively on both sides of the limiting member 202. Therefore, in this structure, during the crimping process, the limiting member 202 can be extruded and deflected outwards.

[0060] Based on the above structure, two setting methods are provided in this embodiment. The lengths of the second slits 7 arranged on both sides of the limiting member 202 are the same or different. When the lengths of the second slits 7 arranged on both sides of the limiting member 202 are the same, after crimping, the limiting member 202 bends outwards and abuts against the insertion hole of the PCB board. When the lengths of the second slits 7 arranged on both sides of the limiting member 202 are different, after crimping, the limiting member 202 bends outwards and deflects and then abuts against the insertion hole of the PCB board.

[0061] At the same time, this embodiment also provides two setting methods, that is, the second slits 7 on the two first wing plates 201 are mirror-symmetric or centrosymmetric. When the second slits 7 are centrosymmetrically arranged, the deflection directions of the two limiting members 202 are different, and the specific structure will not be elaborated here.

[0062] Based on the above structure, the connection part between the lower part of the limiting member 202 and the first wing plate 201 is a bending part, which improves the elastic acting force of the limiting member 202, that is, improves the stable effect of the barb 203 and the limiting member 202 clamping the PCB board.

[0063] Embodiment 6

[0064] At the same time, in this application, in order to better achieve the shielding effect on the wire skin, as Figure 15 shown, in this embodiment, the wrapping isolation plate 302 and the bending groove 303 on the second wing plate 301 are set, especially multiple bending grooves 303 are set on the same wrapping isolation plate 302.

[0065] Although the present invention has been described in detail with general descriptions and specific embodiments above, based on the present invention, some modifications or improvements can be made, which are obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present invention all fall within the scope of protection required by the present invention.
