Throughout this application, unless otherwise specified, "plurality" means two or more.
[0024] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections, direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.
[0025] The present application provides a terminal structure and connector, which are described in detail below with reference to the accompanying drawings. It should be noted that the order in which the following embodiments are described does not limit the preferred order of the embodiments of the present application. Furthermore, in the following embodiments, the descriptions of each embodiment have their own emphasis. For portions not described in detail in one embodiment, please refer to the relevant descriptions of other embodiments.
[0026] Reference Figure 1 and Figure 2The present application provides a terminal structure, which includes a main body 1 and a connecting portion 2. The main body 1 is provided with a through hole extending along a first direction X and has a first end 11 and a second end 12 arranged opposite to each other along the first direction X. The connecting portion 2 includes a first sub-portion 21 and a second sub-portion 22. The first sub-portion 21 and the second sub-portion 22 are both connected to the second end 12 and spliced to form an annular structure. The first sub-portion 21 has a first welding side 211, and the second sub-portion 22 has a second welding side 221. The first welding side 211 is provided with a limiting protrusion 212 protruding toward the second welding side 221, and the second welding side 221 is provided with a limiting groove 222. The limiting protrusion 212 is adapted to the limiting groove 222 to limit the first sub-portion 21 and the second sub-portion 22 in the first direction X.
[0027] Thus, by providing a limiting protrusion 212 and a limiting groove 222 on the first welding side 211 and the second welding side 221, respectively, the limiting protrusion 212 and the limiting groove 222 engage with each other when the two are matched, thereby preventing the two from being misaligned. In addition, due to the enhanced stability of the welding side, the vibration and deformation during the welding process will be reduced, thereby improving the welding quality of both. The stable welding side can ensure the accurate position and alignment of the weld joint and reduce the occurrence of welding defects. At the same time, when welding the first welding side 211 and the second welding side 221, the above design can also increase the contact area to increase the welding strength.
[0028] It is understood that the through hole and the hollow structure between the annular connecting portion 2 together define an accommodating channel. In addition, the first sub-portion 21 has two first welding sides 211 , and the second sub-portion 22 has two second welding sides 221 .
[0029] Reference Figure 3 and Figure 4 The first welding side 211 has a first side 2111 and a second side 2112 opposite to each other along the first direction X, the first side 2111 is close to the second end 12, and the first side 2111 and the second side 2112 have a first distance L1 in the first direction X. The limiting protrusion 212 (see the reference numeral) Figure 2 ) has opposing start and end points in the first direction X, with a second spacing L2 between the start and end points in the first direction X, satisfying the following: L2 = (0.4-0.6) × L1. This arrangement not only prevents the limiting protrusion 212 from being too small to achieve stable positioning between the first sub-section 21 and the second sub-section 22, but also helps improve welding strength.
[0030] In addition, the limiting protrusion 212 (see Figure 2 ) has a starting and ending end and an ending end opposite to each other in the first direction X, and has an outer end opposite to the starting and ending ends in the second direction Y, the starting and ending ends and the ending ends have a second spacing L2 in the first direction X, the outer end and the starting and ending sections have a first size H in the second direction Y, and satisfy: H = (0.2~0.4)×L2, so as to better prevent the size of the limiting protrusion 212 from being too small to achieve stable limiting between the first sub-section 21 and the second sub-section 22, and further improve the welding strength.
[0031] Among them, the first welding side 211 also includes a linear welding segment 213, which extends along the first direction X and is connected to at least one side of the limiting protrusion 212 in the first direction X. The linear welding segment 213 and the limiting protrusion 212 can better prevent the two from misalignment.
[0032] For example, Figure 4 Only the embodiment in which the linear welding section 213 is connected to the lower side of the limiting protrusion 212 in the first direction X is shown. Of course, in other embodiments, the linear welding section 213 may also be connected to the upper side of the limiting protrusion 212 in the first direction X. Alternatively, in other embodiments, the limiting protrusion 212 may be arranged on the upper side of the limiting protrusion 212 in the first direction X. Figure 4 The position shown is moved downward by a certain distance, so that the linear welding segments 213 are formed on both sides of the limiting protrusion 212 in the first direction X.
[0033] In some embodiments of this application, please continue to refer to Figure 3 The main body 1 is composed of two first side walls 13 arranged opposite to each other in the second direction Y, and two second side walls 14 arranged opposite to each other in the third direction Z. A groove 141 is provided on each of the two second side walls 14. The groove 141 is recessed from the second end 12 toward the first end 11 and connects the through hole and the outside of the main body 1. A conductive terminal 142 extending toward the second end 12 is protruded from the bottom of each groove 141. The two first side walls 13 connect the main body 1 and the connecting portion 2. The first direction X, the second direction Y and the third direction Z are perpendicular to each other to achieve electrical connection with the conductive structure in the docking connector.
[0034] The main body 1 is generally waist-shaped, with the two second side walls 14 being flat and the two first side walls 13 being arc-shaped. The two ends of one first side wall 13 are connected to the left ends of the two second side walls 14, respectively, and the two ends of the other first side wall 13 are connected to the right ends of the two second side walls 14, respectively.
[0035] For example, the bottom of each groove 141 is provided with a plurality of conductive terminals 142, and the plurality of conductive terminals 142 are spaced apart along the extension direction of the groove bottom 141. Each conductive terminal 142 has a free end facing away from the groove bottom 141, and a conductive contact 1421 is formed on the outer side wall of each conductive terminal 142, facing away from the through hole of the main body 1, protruding in a direction away from the central axis of the through hole. This improves the contact stability between the conductive terminal 142 and the mating conductive structure, thereby improving the stability of signal transmission between the two.
[0036] Please continue to refer to Figure 1 and Figure 3 The main body 1 includes a first portion and a second portion arranged along the first direction X. The first end 11 is the end of the first portion facing away from the second portion. The groove 141 is provided in the second portion. The depth of the groove 141 is less than the dimension of the second portion in the first direction X and greater than the extended length of the conductive terminals 142. In other words, each conductive terminal 142 has a free end facing away from the bottom of the groove 141. A gap X1 is formed between the free end of the conductive terminal 142 and the connecting portion 2 in the first direction X to prevent contact or interference between the conductive terminal 142 and the connecting portion 2 during deformation fit.
[0037] In order to increase the stability of signal transmission between the terminal structure and the mating conductive structure, at least one of the first side walls 13 is provided with a conductive contact portion 131 , which protrudes in a direction away from the central axis of the through hole.
[0038] Please continue to refer to Figure 1 The main body 1 includes a first part and a second part arranged along the first direction X, the first end 11 is the end of the first part away from the second part, and the second end 12 is the end of the second part facing away from the first part. The size of the first part is larger than the size of the second part, and the size of the second part is larger than the size of the connecting part 2, so that the above-mentioned terminal structure is roughly divided into three parts when viewed in the first direction X, and a step structure is formed between the three parts, thereby increasing the structural strength of the terminal structure.
[0039] like Figure 5 As shown, a foolproof structure 15 is provided on the outer peripheral side of the main body 1 to mark the front and back sides of the terminal structure to ensure that the terminal structure is docked to the docking connector in the correct direction.
[0040] In some embodiments, the limiting protrusion 212 has a connecting side (the starting and ending ends of the limiting protrusion 212 are both located on the connecting side) and an outer side that are opposite to each other in the second direction Y. The size of the connecting side in the first direction X is larger than that of the outer side, so as to facilitate the snap-fitting between the limiting protrusion 212 and the limiting groove 222. For example, the limiting protrusion 212 is arc-shaped, triangular or trapezoidal, and the shape and size of the limiting groove 222 are adapted to the limiting protrusion 212. Figures 1 to 4 2 shows an embodiment in which the limiting protrusion 212 is arc-shaped. In other words, the size of the limiting protrusion 212 in the first direction X gradually decreases from the first welding side 211 to the second welding side 221 .
[0041] It should be noted that Figure 6 This is a front view of another terminal structure in the embodiment of the present application, wherein the other terminal structure is Figure 1 The difference between the terminal structures shown is only the shape of the limiting protrusion 212. The limiting protrusion 212 in the other terminal structure is triangular.
[0042] In some embodiments of the present application, the limiting protrusion 212 protrudes along the second direction Y, the limiting groove 222 is recessed in a direction away from the first welding side 211, and may or may not penetrate the second welding side 221 in the third direction Z. The first direction X, the second direction Y, and the third direction Z are perpendicular to each other.
[0043] Specifically, when the limiting groove 222 passes through the second welding side 221 in the third direction Z, the size of the limiting groove 222 in the third direction Z is equal to the size of the limiting protrusion 212 in the third direction Z. Figure 1 and Figure 6 As shown, the manufacturing process of the limiting protrusion 212 and the limiting groove 222 is relatively simple and easy to implement.
[0044] When the limiting groove 222 does not penetrate the second welding side 221 in the third direction Z, the limiting groove 222 has a stop side portion 223 perpendicular to the third direction Z. In the third direction Z, the limiting protrusion 212 and the stop side portion 223 are stacked. Figure 7 Such an arrangement not only enables the first sub-section 21 and the second sub-section 22 to be limited in the third direction Z, but also allows the stop side portion and the limiting protrusion 212 to form a welding surface on the surfaces of the stacked opposite sides in the third direction Z, thereby further increasing the connection strength between the two.
[0045] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.
[0046] The above is only a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any person skilled in the art can easily think of changes or replacements within the technical scope disclosed in the present application, which should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims. In addition, the specification uses specific examples to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method and core ideas of the present application. The content of this specification should not be understood as limiting the present application.
