[0068] To fully understand the purpose, features and effects of the present invention, the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0069] In this invention, the terms "a" or "an" are used to describe the units, elements, and components described herein. This is used merely for ease of explanation and to provide a general meaning regarding the scope of the invention. Therefore, unless it is clearly intended otherwise, this description should be understood to include one, at least one, and the singular also includes the plural.

[0070] In this invention, the terms "comprising," "including," "having," "containing," or any other similar terms are intended to cover non-exclusive inclusions. For example, an element, structure, article of manufacture, or device containing a plurality of elements is not limited to those listed herein, but may include other elements not expressly listed but which are typically inherent to that element, structure, article of manufacture, or device. Furthermore, unless expressly stated to the contrary, the term "or" is inclusive, not exclusive.

[0071] Please refer to Figures 1(a) and 1(b), which are three-dimensional schematic diagrams illustrating the wire-to-board connector. Figure 1(a) is a first-view three-dimensional schematic diagram of the wire-to-board connector, and Figure 1(b) is a second-view three-dimensional schematic diagram of the wire-to-board connector.

[0072] The wire-to-board connector 10 is embedded in a circuit board 2 with a thickness d, which can also be referenced. Figure 2 Figure 1(a) and Figure 1(b) are perspective schematic diagrams illustrating the wire-to-board connector embedded in the circuit board of the present invention.

[0073] The wire-to-board connector 10 includes a plug 12, a fastener 14, a socket 16, and a plurality of second electrodes 18. In another embodiment, the wire-to-board connector 10 may also include an upper housing 20.

[0074] Here, plug 12 is illustrated using a rectangular shape as an example, which can also be used for reference. Figures 3(a) to 3(c) To illustrate the plug of the wire-to-board connector of FIG1(a) and FIG1(b) of the present invention from various perspectives, FIG3(a) is a front view illustrating the plug of the wire-to-board connector of FIG1(a) and FIG1(b) of the present invention; FIG3(b) is a side view illustrating the plug of the wire-to-board connector of FIG1(a) and FIG1(b) of the present invention; and FIG3(c) is a rear view illustrating the plug of the wire-to-board connector of FIG1(a) and FIG1(b) of the present invention.

[0075] The plug 12 forms a second snap-fit ​​groove 122 with a plurality of first protrusions 1222, an accommodating space SP, and a plurality of first electrode holes 124. The plurality of first electrode holes 124 can be used to accommodate cables (not shown), and the number of the plurality of first electrode holes 124 is greater than or equal to the number of cables; therefore, the number of first electrode holes 124 is not limited. Furthermore, a first side surface 126 and a second side surface 128 of the plug 12 are defined here, according to which the second snap-fit ​​groove 122 is formed on the first side surface 126 and the plurality of first electrode holes 124 are formed on the second side surface 128.

[0076] In another embodiment, the plug 12 further includes V-shaped clamping structures 130 formed on both sides of the plug 12 for mechanical clamping to assemble the connector.

[0077] In another embodiment, the plug 12 further includes a plurality of first stops 1210, which can also be seen with reference to FIG6(b). Wherein, in Figure 6(a) and 6(b) In Figure 6(a), a top view illustrating a wire-to-board connector according to an embodiment of the present invention is shown; and in Figure 6(b), a cross-sectional view AA illustrating the wire-to-board connector of Figure 6(a) of the present invention is shown. In Figure 6(b), the plurality of first stops 1210 are formed in the accommodating space SP.

[0078] Next, let's explain fastener 14, which can also be referenced. Figure 4 The following is a perspective view of the fastener of the wire-to-board connector shown in Figures 1(a) and 1(b) of the present invention.

[0079] Herein, the fastener 14 forms a plurality of second protrusions 142 and a first segment snap-fit ​​structure 144. The plurality of second protrusions 142 are provided corresponding to the equal first protrusions 1222. When the fastener 14 is driven by an external force, the fastener 14 can rotate through the interaction of the plurality of second protrusions 142 and the plurality of first protrusions 1222.

[0080] Therefore, the first segment snap-fit ​​structure 144 can be designed to accommodate circuit boards 2 of varying thicknesses d, in conjunction with the second segment snap-fit ​​structure 166 mentioned later. Figure 4 The disclosed structures are merely illustrative examples. In fact, the present invention is not limited to any particular structure. As long as the first segment snap-fit ​​structure 144 and the second segment snap-fit ​​structure 166 can be used to assemble circuit boards 2 of different thicknesses d without redesigning or remolding, that is, the wire-to-board connector 10 can still achieve the snap-fit ​​function by fully, partially, or partially snapping together when engaging circuit boards 2 of different thicknesses d, they all fall within the scope of the invention of the first segment snap-fit ​​structure 144 and the second segment snap-fit ​​structure 166 mentioned in the present invention.

[0081] exist Figure 4 For example, the first segment of the latching structure 144 comprises a plurality of first latching blocks 1442 and a plurality of third latching blocks 1444, wherein the plurality of first latching blocks 1442 have a first inclined surface and the plurality of third latching blocks 1444 have a third inclined surface. The height H1 of the plurality of first latching blocks 1442 protruding from the surface S1 of the fastener 14 is higher than the height H2 of the plurality of third latching blocks 1444 protruding from the surface S1 of the fastener 14.

[0082] Here, socket 16 is also illustrated using a rectangular shape as an example, which can be referred to as well. Figures 5(a) to 5(d) To illustrate the perspective views of the socket-connected upper housing of Figures 1(a) and 1(b) of the present invention, Figure 5(a) is a perspective view illustrating the socket-connected upper housing of Figures 1(a) and 1(b) of the present invention; Figure 5(b) is a front view illustrating the socket-connected upper housing of Figures 1(a) and 1(b) of the present invention; Figure 5(c) is a side view illustrating the socket-connected upper housing of Figures 1(a) and 1(b) of the present invention; and Figure 5(d) is a rear view illustrating the socket-connected upper housing of Figures 1(a) and 1(b) of the present invention.

[0083] The socket 16 forms a plurality of guide members 162, a plurality of second electrode holes 164, and a second segment snap-fit ​​structure 166. The socket 16 is guided through the plurality of guide members 162 to the receiving space SP of the plug 12 so that the plurality of second electrode holes 164 are disposed in the receiving space SP. Furthermore, the second electrode holes 164 can be used to house the plurality of second electrodes 18 (as shown in FIG1).

[0084] It is worth noting that at the junction of the socket 16 and the plug 12, a chamfer design can be selectively formed, such as the chamfers 1214 and 1614 in Figure 6(b), so that the socket 16 and the plug 12 can be easily assembled and disassembled.

[0085] Furthermore, for the sake of the following explanation, please refer to Figure 5(c) as well. Here, the first side 168 and the second side 1610 of the socket 16 are defined. According to this definition, the second segment snap-fit ​​structure 166 is formed on the first side 168, and the corresponding side of the socket 16 on which the second segment snap-fit ​​structure 166 is not formed is the second side 1610.

[0086] In this embodiment, the upper housing 20 may form a plurality of first fixing members (not shown) and the socket 16 may further include a plurality of second fixing members (not shown). The plurality of first fixing members are provided corresponding to the second fixing members. The upper housing 20 and the socket 16 may be combined through the plurality of first fixing members and the second fixing members. For example, the plurality of first fixing members and the plurality of second fixing members may be designed as a groove and a hook for each other, the purpose of which is to fix the upper housing 20 to the socket 16, so that the second electrode 18 assembled in the socket 16 can obtain protection and insulation.

[0087] Therefore, the second segment snap-fit ​​structure 166 can be designed in conjunction with the aforementioned first segment snap-fit ​​structure 144 to accommodate circuit boards 2 of different thicknesses d. The structure shown in FIG5(b) is merely illustrative and not limited to any particular structure. As long as the second segment snap-fit ​​structure 166 and the first segment snap-fit ​​structure 144 can still achieve a snap-fit ​​effect by fully, partially, or partially snapping together after being connected to the wire-to-board connector 10 on circuit boards 2 of different thicknesses d, they all fall within the scope of the invention of the second segment snap-fit ​​structure 166 and the first segment snap-fit ​​structure 144 mentioned in this invention.

[0088] exist Figure 5(a) and 5(b)In the second segment, the latching structure 166 comprises a plurality of first latching slots 1662 and a plurality of third latching blocks 1664. The plurality of first latching slots 1662 correspond to the plurality of first latching blocks 1442, and the plurality of third latching slots 1664 correspond to the plurality of third latching blocks 1444. The plurality of first latching slots 1662 and the plurality of first latching blocks 1442 latch at a first latching point A, and the plurality of third latching slots 1664 and the plurality of third latching blocks 1444 latch at a third latching point B. After the plug 12 and socket 16 are combined, the distance from the first latching point A to the surface of the circuit board 2 is greater than or equal to the distance from the third latching point B to the surface of the circuit board 2. Therefore, by using the different heights of the first latching point A and the third latching point B, and by coordinating the first latching block 1442 and the plurality of third latching blocks 1444 protruding from the surface S1 of the fastener 14 at heights H1 and H2 respectively, the wire-to-board connector 10 can achieve the purpose of latching when combined with circuit boards 2 of different thicknesses d. This can also be referred to... Figures 7(a) to 7(c) The following are explanatory schematic diagrams illustrating the combination of the first segment snap-fit ​​structure and the second segment snap-fit ​​structure of the present invention: Figure 7(a) is a top view illustrating the combination of the first segment snap-fit ​​structure and the second segment snap-fit ​​structure of the present invention; Figure 7(b) is a BB cross-sectional view illustrating the combination of the first segment snap-fit ​​structure and the second segment snap-fit ​​structure of Figure 7(a) of the present invention; and Figure 7(c) is an external schematic diagram illustrating the combination of the first segment snap-fit ​​structure and the second segment snap-fit ​​structure of Figure 7(a) of the present invention.

[0089] In Figure 7(a), it is shown that the first segment snap-fit ​​structure 144 and the second segment snap-fit ​​structure 166 can be designed to operate within the range of 0.8 mm to 1.2 mm thickness of the circuit board 2. That is, when the thickness of the circuit board 2 is 0.8 mm, the plurality of third snap-fit ​​slots 1664 and the plurality of third snap-fit ​​blocks 1444 can be fully snapped together; and if the thickness of the circuit board 2 is greater than 0.8 mm, for example, 1.0 mm (or 1.2 mm), the plurality of third snap-fit ​​slots 1664 and the plurality of third snap-fit ​​blocks 1444 can no longer be snapped together, but they can still be partially or incompletely snapped together through the plurality of first snap-fit ​​slots 1662 and the plurality of first snap-fit ​​blocks 1442.

[0090] In the BB cross-sectional view shown in Figure 7(b), to illustrate that when the plug 12 is inserted into the circuit board 2 with a thickness of 1.0 mm (or 1.2 mm), the plurality of third latching slots 1664 and the plurality of third latching blocks 1444 cannot be fully latched. The plurality of first latching slots 1662 and the plurality of first latching blocks 1442 need to partially or incompletely latch the plug. From the appearance of the fastener 14, when the fastener 14 partially or incompletely latches the second segment latching structure 166, the fastener 14 forms the first segment. The surface S1 of the snap-fit ​​structure 144 and the surface S2 of the circuit board 2 are inclined and clamped at an angle; furthermore, Figure 7(c) shows a schematic diagram of the appearance of the first segment snap-fit ​​structure combined with the second segment snap-fit ​​structure, which shows that when the plug 12 is inserted into the circuit board 2 with a thickness of 0.8mm, the plurality of third snap-fit ​​slots 1664 and the plurality of third snap-fit ​​blocks 1444 can be fully snapped together, so that the surface S1 of the first segment snap-fit ​​structure 144 of the fastener 14 clamps the surface S2 of the circuit board 2 at a 90-degree angle or close to a 90-degree angle.

[0091] In another embodiment, also referring to FIG6(b), the socket 16 further includes a plurality of second stops 1612, which cooperate with the aforementioned first stops 1210 to lock together when the plug 12 is engaged with the socket 16. Here, the plurality of second stops 1612 are described as protrusions and the first stops 1210 as recesses. It is worth noting that the plurality of first stops 1210 and the plurality of second stops 1612 can prevent the buckle 14 from being lifted due to pulling the cable during installation, thus preventing the plug 12 from separating from the socket 16.

[0092] At the same time, it can also be understood from Figure 6(b) that the bottom of the plug 12 can be attached to the circuit board 2.

[0093] In another embodiment, referring also to FIG6(a), the socket 16 further forms a plurality of guide posts 1616 and the plug 12 further forms a plurality of first openings 1216. The plurality of first openings 1216 are provided corresponding to the plurality of guide posts 1616, and the plurality of guide posts 1616 are inserted into the plurality of first openings 1216 by the plug 12 engaging with the socket 16. Besides serving the purpose of fixing and positioning, the plurality of first openings 1216 can also be used to observe whether the plurality of guide posts 1616 are correctly inserted into the plurality of first openings 1216.

[0094] In another embodiment, referring also to FIG6(a), the plug 12 may further form a plurality of second openings 1212, the positions of which correspond to the plurality of second stops 1612, so as to be able to observe the latching state of the plurality of first stops 1210 and the plurality of second stops 1612.

[0095] According to the above description, after the socket 16 is installed on the circuit board 2, the plug 12 engages with the socket 16 so that the bottom of the plug 12 can be attached to the surface of the circuit board 2. The thickness of the circuit board 2 can be used to determine that the first segment snap-fit ​​structure 1210 has a distance from the surface of the circuit board 2. When the distance is within a predetermined snap-fit ​​range, for example, the predetermined snap-fit ​​range is related to the thickness d of the circuit board 2, and the thickness d is between 0.6 mm and 1.4 mm, at least a portion of the first segment snap-fit ​​structure 1210 snaps the second segment snap-fit ​​structure 1612 so that the plug 12 does not detach from the fastener 14.

[0096] The present invention has been disclosed above with reference to preferred embodiments. However, those skilled in the art should understand that the embodiments are merely illustrative of the invention and should not be construed as limiting its scope. It should be noted that all variations and substitutions equivalent to the embodiments should be considered within the scope of the present invention. Therefore, the scope of protection of the present invention is defined by the claims.
