Description

Technical Field

[0001] This utility model relates to the field of electronic component technology, and in particular discloses a three-way interlocking PCB terminal structure. Background Technology

[0002] In modern electronic devices, printed circuit boards (PCBs) are crucial electronic components, playing a key role in connecting various electronic elements. PCB terminals, as vital components for achieving electrical connections between the PCB and other parts, directly impact the performance and reliability of electronic devices through their structural design. With the miniaturization and integration of electronic devices, higher demands are placed on the space utilization efficiency and connection flexibility of PCB terminals. Traditional PCB terminal structures typically only enable connections in one or a limited number of directions. When multi-directional electrical connections are required, multiple terminals often need to be combined, which not only increases the difficulty of PCB layout but also occupies a significant amount of space, leading to increased production costs, larger device size, and reduced connection stability and reliability. Therefore, developing a PCB terminal structure that enables multi-directional interlocking, high space utilization, and stable connections has become an urgent problem to be solved in the field of electronic components.

The guide portion includes a first guide ear on the first clamping plate and a second guide ear on the second clamping plate. The first guide ear and the second guide ear are located inside the cavity. The first guide ear and the second guide ear are inclined. The distance between the end of the first guide ear near the first clamping plate and the end of the second guide ear near the second clamping plate is less than the distance between the end of the first guide ear away from the first clamping plate and the end of the second guide ear away from the second clamping plate.

[0024] Please see Figures 1 to 5 As shown, this utility model discloses a three-way plug-in PCB terminal structure, including a female terminal component. The female terminal component has a conductive body 1, and a first plug-in interface 2, a second plug-in interface 3, and a third plug-in interface 4 disposed on the conductive body 1. An external male terminal is inserted into the plug-in interface and electrically connected to the conductive body 1. The conductive body 1 has a cavity 5. The first plug-in interface 2 communicates with the cavity 5 to form a first plug-in channel, the second plug-in interface 3 communicates with the cavity 5 to form a second plug-in channel, and the third plug-in interface 4 communicates with the cavity 5 to form a third plug-in channel. The extension direction of the first plug-in channel is parallel to the extension direction of the second plug-in channel, and the extension direction of the third plug-in channel is intersected with the extension direction of the first plug-in channel.

[0025] In actual use, the female terminal is C-shaped, with the first and second insertion channels located at the upper and lower ends of the female terminal, respectively, and the third insertion channel located at the side end of the female terminal. External male terminals can enter the cavity 5 of the female terminal via the first, second, or third insertion channels. The female terminal is integrally formed and made of metal.

[0026] Specifically, the conductive body 1 has a main body and a first side plate 6 and a second side plate 7 protruding from both sides of the main body. The main body, the first side plate 6 and the second side plate 7 surround to form a cavity 5. The first insertion interface 2 and the second insertion interface 3 are respectively located at both ends of the cavity 5, and the first insertion channel and the second insertion channel are connected.

[0027] In actual use, the main body, the first side plate 6, and the second side plate 7 are integrally stamped. The main body, the first side plate 6, and the second side plate 7 form a cavity 5. One end of the main body, one end of the first side plate 6, and one end of the second side plate 7 form a first insertion interface 2, which communicates with the cavity 5 to form a first insertion channel. The other end of the main body, the other end of the first side plate 6, and the other end of the second side plate 7 form a second insertion interface 3, which communicates with the cavity 5 to form a second insertion channel.

[0028] Specifically, the conductive body 1 is provided with a first clamping plate 61 and a second clamping plate 71 on the side facing the cavity 5. After the external male terminal enters the cavity 5 through the first plug-in interface 2, the second plug-in interface 3 or the third plug-in interface 4, the first clamping plate 61 and the second clamping plate 71 cooperate to clamp and connect the external male terminal.

[0029] In actual use, the first clamping plate 61 and the second clamping plate 71 are arranged opposite to each other, respectively, on the first side plate 6 and the second side plate 7. A groove is formed between the first clamping plate 61 and the second clamping plate 71. The first insertion interface 2 forms a first insertion channel with the groove, the second insertion interface 3 forms a second insertion channel with the groove, and the third insertion interface 4 forms a third insertion channel with the groove. The external male terminal is in electrical contact with the first clamping plate 61 and the second clamping plate 71.

[0030] Specifically, the first clamping plate 61 is connected to the first side plate 6 via the first connecting part 62, and the second clamping plate 71 is connected to the second side plate 7 via the second connecting part 72; the first connecting part 62 and the second connecting part 72 are U-shaped; the first connecting part 62 and the second connecting part 72 are elastic to increase the clamping force of the first clamping plate 61 and the second clamping plate 71.

[0031] In actual use, the first clamping plate 61 is mounted on the first side plate 6, and the second clamping plate 71 is mounted on the second side plate 7. One end of the first clamping plate 61 is bent toward the first side plate 6 to form a U-shaped first connecting portion 62, and one end of the second clamping plate 71 is bent toward the second side plate 7 to form a U-shaped second connecting portion 72. The first clamping plate 61, the second clamping plate 71, the first side plate 6, and the second side plate 7 are integrally formed. The first connecting portion 62 and the second connecting portion 72 have a certain degree of elasticity and flexibility, allowing the distance between the first clamping plate 61 and the second clamping plate 71 to change to a certain extent when an external male terminal is inserted between the first clamping plate 61 and the second clamping plate 71, thereby increasing the clamping force of the first clamping plate 61 and the second clamping plate 71 on the external male terminal.

[0032] Specifically, the first clamping plate 61 is provided with a first protrusion 63, and the second clamping plate 71 is provided with a second protrusion 73. The first protrusion 63 rises from the body of the first clamping plate 61 toward the second clamping plate 71, and the second protrusion 73 rises from the body of the second clamping plate 71 toward the first clamping plate 61. The first protrusion 63 and the second protrusion 73 respectively abut against both sides of the external male terminal.

[0033] In actual use, the middle part of the first clamping plate 61 protrudes towards the second clamping plate 71, and the first clamping plate 61 as a whole has a > shape. The middle part of the second clamping plate 71 protrudes towards the first clamping plate 61, and the second clamping plate 71 as a whole has a < shape. The external male terminal is clamped by the first protrusion 63 and the second protrusion 73.

[0034] Specifically, the distance between the end of the first clamping plate 61 near the first connecting portion 62 and the end of the second clamping plate 71 near the second connecting portion 72 is greater than the distance between the first protrusion 63 and the second protrusion 73. The end of the first clamping plate 61 near the first connecting portion 62 and the end of the second clamping plate 71 near the second connecting portion 72 form a flared first insertion channel. The distance between the end of the first clamping plate 61 away from the first connecting portion 62 and the end of the second clamping plate 71 away from the second connecting portion 72 is greater than the distance between the first protrusion 63 and the second protrusion 73. The end of the first clamping plate 61 away from the first connecting portion 62 and the end of the second clamping plate 71 away from the second connecting portion 72 form a flared second insertion channel.

[0035] In actual use, the first insertion channel is formed by the first clamping plate 61 near the first connecting portion 62, the second clamping plate 71 near the second connecting portion 72, and the conductive body 1. The diameter of the first insertion channel near the first protrusion 63 and the second protrusion 73 is smaller than the diameter of the first insertion channel away from the first protrusion 63 and the second protrusion 73, making the first insertion channel flared outwards, facilitating the clamping of the external male terminal. The second insertion channel is formed by the first clamping plate 61 away from the first connecting portion 62, the second clamping plate 71 near the second connecting portion 72, and the conductive body 1. The diameter of the second insertion channel near the first protrusion 63 and the second protrusion 73 is smaller than the diameter of the second insertion channel away from the first protrusion 63 and the second protrusion 73, making the second insertion channel flared outwards, facilitating the clamping of the external male terminal.

[0036] Specifically, the conductive body 1 is further provided with a guide portion on the side facing the cavity 5. The guide portion includes a first guide ear 64 provided on the first clamping plate 61 and a second guide ear 74 provided on the second clamping plate 71. The first guide ear 64 and the second guide ear 74 are located inside the cavity (5). The first guide ear 64 and the second guide ear 74 are inclined. The distance between the end of the first guide ear 64 near the first clamping plate 61 and the end of the second guide ear 74 near the second clamping plate 71 is smaller than the distance between the end of the first guide ear 64 away from the first clamping plate 61 and the end of the second guide ear 74 away from the second clamping plate 71. The first guide ear 64 and the second guide ear 74 form a flared third insertion channel.

[0037] In actual use, the guide part is used to guide the external male terminal to be inserted into the female terminal piece from the third insertion interface 4. The guide part continues to extend towards the first side plate 6 and the second side plate 7 on the original basis, and abuts against the first side plate 6 and the second side plate 7 to improve the stability of lateral insertion.

[0038] Specifically, the conductive body 1 has a first baffle 65 and a second baffle 75 that are coplanar and spaced apart. The gap between the first baffle 65 and the second baffle 75 forms a third insertion interface 4, and the first baffle 65 and the second baffle 75 respectively block the free end of the first guide ear 64 and the free end of the second guide ear 74.

[0039] In actual use, the free end of the first side plate 6 bends and extends towards the second side plate 7 to form a first baffle 65, and the free end of the second side plate 7 bends and extends towards the first side plate 6 to form a second baffle 75. There is a gap between the first baffle 65 and the second baffle 75, which serves as the third insertion interface 4. The first guide ear 64 is covered by the first baffle 65, and the second guide ear 74 is covered by the second baffle 75. The first connecting part 62 is covered by the first baffle 65 via the main body of the conductive body 1, and the second connecting part 72 is covered by the second baffle 75 via the main body of the conductive body 1. The first baffle 65 and the first side plate 6 are integrally formed, and the second baffle 75 and the second side plate 7 are integrally formed.

[0040] Specifically, the conductive body 1 has a plug pin 8 on the side facing the external plate end. The conductive body 1 is electrically connected to the external plate end via the plug pin 8. The external plate end has a plug-in hole that communicates with the first plug interface 2 or the second plug interface 3.

[0041] In actual use, there are two external feet, located at the middle of the end of the first side plate 6 facing the outer plate and the middle of the end of the second side plate 7 facing the outer plate, respectively. The external feet are integrally formed with the first side plate 6 and the second side plate 7.

[0042] Specifically, the free ends of the first guide ear 64, the second guide ear 74, and / or the free ends of the first clamping plate 61 and the second clamping plate 71 respectively have a contact portion for abutting against the inner wall of the cavity 5.

[0043] In actual use, the contact part abuts against the inner wall of the cavity 5, which helps to enhance the strength of the first guide ear 64, the second guide ear 74, the first clamping plate 61 and the second clamping plate 71, and prevents the first guide ear 64, the second guide ear 74, the first clamping plate 61 and the second clamping plate 71 from deforming and breaking when the female terminal component is vibrated.

[0044] Preferably, the contact part has an outwardly protruding arc that abuts against the inner wall of the cavity 5, reducing the scratching damage of the contact part to the inner wall of the cavity.

[0045] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
