[0045] The following is a detailed discussion of the embodiments of the present disclosure. However, it is understood that the embodiments provide many applicable concepts that can be implemented in a variety of specific contents. The embodiments discussed and disclosed are for illustration only and are not intended to limit the scope of the present disclosure. All embodiments of the present disclosure disclose a variety of different features, but these features can be implemented individually or in combination as needed. It should be noted that the figures are drawn according to the actual scale of the product. In order to maintain the simplicity of the specification, the scale of each component is not listed one by one, but the scale and position of each component should be regarded as part of the content of this specification. Furthermore, if the description of this specification is not sufficient to explain the detailed design of the component and it cannot be implemented, the contents of CN102763289B or CN1081837C patents may be referred to.

[0046] In addition, the terms "first", "second", etc. used herein do not specifically refer to order or sequence, but are only used to distinguish between elements or operations described with the same technical terms. In addition, the spatial relationship between two elements described in the present disclosure applies not only to the orientations shown in the drawings, but also to orientations not shown in the drawings, such as an inverted orientation.

[0047] Please refer to Figures 1 to 5 An embodiment of the present disclosure provides a connector 100 (first connector), which can be used in, for example, the field of high-current connectors, for coupling with another connector 300 (second connector) and conducting electrical energy.

[0048] In this embodiment, the first connector 100 is mainly composed of a first connector assembly 200 , two fasteners 400 and a cable 500 .

[0049] See Figure 3 The first connector assembly 200 is mainly composed of a first shell 210, an outer frame 220, a base assembly 230, a plurality of rod-shaped power supply terminals 240 and at least one ground terminal 250.

[0050] The base assembly 230 includes an integrally formed insulating plastic base and a plurality of back covers snapped onto the base. There are a plurality of through holes with platforms inside the base for inserting the shorter female power terminals 240 and the longer male ground terminals 250. At the same time, the back covers (not shown) are used to fix the terminals in the through holes. The base assembly 230 can be embedded and fixed in the hollow outer frame 220. The multiple wires in the cable 500 are electrically connected to the ends of the power terminals 240 and the ground terminals 250, respectively. In this example, since the male ground terminal 250 is longer, the surface of the base facing the first shell 210 is stepped, that is, Figure 3 The right side of the center base is thicker than the other end.

[0051] In this example, the first shell 210 is a molded plastic part. In this example, the first shell 210 includes an inner mold 211 and an outer mold 212. The inner mold 211 is formed on the outer frame 220 and one end of the base assembly 230 by an injection molding process and covers the outer surface of the cable 500 at the same time. The outer mold 212 is also covered on the outside of the inner mold 211 in the same manner and fixed to the outer frame 220. Compared with the traditional assembly design, forming the first shell 210 by the injection molding process can effectively improve the waterproof performance. To be more specific, the aforementioned injection molding process can be an embedded molding process. Correspondingly, by Figure 3 and Figure 4 The outer contour of the first housing 210 in the figure shows that the lateral surface of the outer mold 212 protrudes two tapered stepped hollow cylindrical structures, and the hollow part allows the cable 500 to pass through. The lateral surface (side surface 213) of the inner mold 211 also has a protruding hollow cylindrical structure, and the hollow part allows the cable 500 to pass through.

[0052] On the other hand, the cable 500 passes through the first housing 210 vertically along the width direction of the fastener 400 from the inside of the first housing 210 through its lateral surface. In another example, the first housing 210 can also be made of assembled components, and the present invention is not limited to this.

[0053] like Figure 4 and Figure 5 As shown, the first housing 210 has two side surfaces 213 and 214 opposite to each other, and two supporting columns 216 are respectively provided on the two side surfaces 213 and 214. The positions of the two supporting columns 216 on the side surface 213 are respectively aligned with the two supporting columns 216 on the side surface 214. The supporting columns 216 can be, for example, cylindrical structures, so that the fastener 400 can be pivoted around them as a rotating axis.

[0054] The second housing 310 of the second connector 300 is located below the first housing 210. The second housing 310 may be a molded plastic part. Figure 4 and Figure 5 As shown, the second housing 310 has two side surfaces 312 and 314 opposite to each other, wherein the side surfaces 312 and 314 are respectively located below the side surfaces 213 and 214 of the first housing 210. Two buckling columns 316 are respectively provided on the side surfaces 312 and 314. The positions of the buckling columns 316 on the side surfaces 312 and 314 are aligned. In addition, the buckling columns 316 can be aligned with the supporting columns 216, for example. In this example, the buckling columns 316 are cylindrical structures.

[0055] Please refer to Figure 6 and Figure 7 , which respectively illustrate a three-dimensional schematic diagram of a fastener 400 according to an embodiment of the present disclosure, and a cross-sectional schematic diagram of the fastener 400 cut along line AA. The fastener 400 can be used to tightly fasten the first connector component 200 of the first connector 100 and the second connector 300 together. In this embodiment, the fastener 400 is mainly composed of a handle 410 and two baffles 420. The handle 410 allows the user to pull the fastener 400 to perform a fastening or unfastening operation. The handle 410 can be, for example, a plate-like structure. The handle 410 can be a molded plastic part. In this example, the handle 410 and the two baffles 420 are integrally formed.

[0056] The two baffles 420 are respectively disposed at two opposite ends of the handle 410 and are opposite to each other, and form a U-shaped structure with the handle 410. In detail, the two baffles 420 are vertically connected to the two ends of the handle 410. Each baffle 420 may mainly include a main body 422 and a metal sheet 424. The main body 422 may be a molded plastic part. In one embodiment, the handle 410 and the main body 422 are an integrally molded structure. The main body 422 has a front end portion 422a, a pivot portion 422b, a locking portion 422c, a first opening 422d, a second opening 422e, a third opening 422f, and a fourth opening 422g. The front end portion 422a is an end portion of the main body 422 that is farther away from the handle 410. The pivot portion 422b and the locking portion 422c are recessed in the front end portion 422a, wherein the pivot portion 422b is located above the locking portion 422c. As shown in FIG. Figure 6 As shown, the pivoting portion 422b has an arc-shaped inner side surface 422b', and the locking portion 422c may have an arc-shaped inner side surface 422c'. Figure 6 As shown in the right part, the outer surface of the main body 422 is provided with a protruding outer reinforcing rib 422 k, and the outer reinforcing rib 422 k extends horizontally along the length direction of the main body 422.

[0057] like Figure 6 As shown, the first opening 422d is located in the inner side surface 422b' of the pivoting portion 422b, and the second opening 422e is located in the inner side surface 422c' of the locking portion 422c. Figure 7 As shown, the third opening 422f is located in the top surface 422h of the body 422, and the fourth opening 422g is located in the bottom surface 422i of the body 422. The first opening 422d, the second opening 422e, the third opening 422f, and the fourth opening 422g can be interconnected to form a space for the metal sheet 424 to be accommodated therein.

[0058] The metal sheet 424 is embedded in the main body 422. In one embodiment, as Figure 6 and Figure 7 As shown, the metal sheet 424 can extend from the top surface 422h of the main body 422 through the pivot portion 422b and the locking portion 422c in sequence to the bottom surface 422i adjacent to the main body 422. In another embodiment, the metal sheet 424 can extend to the bottom surface 422i of the main body 422. The metal sheet 424 has an anti-wear portion 424a, which is located in the second opening 422e and exposed at the second opening 422e. In one embodiment, the anti-wear portion 424a of the metal sheet 424 is flush with the inner side surface 422c' of the locking portion 422c. The so-called flush means that the height difference of the two surfaces is smaller than the tolerance range of 2mm. For example, when the height of the anti-wear portion 424a of the metal sheet 424 protruding from the inner side surface 422c' of the locking portion 422c is 1mm, the two are said to be flush. In another embodiment, the anti-wear portion 424a of the metal sheet 424 protrudes from the inner side surface 422c' of the locking portion 422c. The so-called protrusion means that the height difference between the two surfaces is greater than or equal to 2 mm.

[0059] Thus, the anti-wear portion 424 a of the metal sheet 424 can prevent the inner side surface 422 c ′ of the locking portion 422 c from being excessively worn and causing damage to the main body 422 of the baffle 420 , thereby extending the service life of the fastener 400 .

[0060] In one embodiment, the metal sheet 424 is located in the first opening 422d, the second opening 422e, and the third opening 422f. Figure 6 and Figure 7 As shown, the metal sheet 424 has an opening 424b and a notch 424c, wherein the opening 424b corresponds to the pivoting portion 422b, and the notch 424c corresponds to the locking portion 422c. In one embodiment, the opening 424b of the metal sheet 424 is aligned with the pivoting portion 422b, and the anti-wear portion 424a of the metal sheet 424 is located in the notch 424c. In another embodiment, the opening 424b of the metal sheet 424 is exposed in the first opening 422d located in the inner side 422b' of the pivoting portion 422b.

[0061] Please also refer to Figures 4 to 7, the four support columns 216 on the first housing 210 of the first connector assembly 200 can be respectively inserted into the pivoting portions 422b of the main bodies 422 of the two baffles 420, and can be inserted into the openings 424b of the metal sheet 424. The support columns 216 are pivotally connected to the pivoting portions 422b and the metal sheet 424, whereby the fastener 400 can rotate using the support columns 216 as a rotation axis. Since the support columns 216 are inserted into the openings 424b of the metal sheet 424, the metal sheet 424 is more wear-resistant than the pivoting portions 422b made of plastic, thereby effectively extending the service life of the baffle 420.

[0062] When the fastener 400 is fastened, the fastener 400 pivots toward the direction of the fastening column 316 on the second housing 310 of the second connector 300, so that each fastening column 316 is fastened into the locking portion 422c of the main body 422 and the notch 424c of the metal sheet 424, so that the first housing 210 and the second housing 310 can be pressed against each other. Since the anti-wear portion 424a of the metal sheet 424 is exposed in the second opening 422e located in the inner side 422c' of the locking portion 422c, when the fastening column 316 is fastened into the locking portion 422c, the fastening column 316 can slide through the anti-wear portion 424a. Since the metal sheet 424 is more wear-resistant, the design of the anti-wear portion 424a being exposed in the locking portion 422c can improve the durability of the baffle 420 and effectively extend the service life of the fastener 400.

[0063] In addition, see Figure 6 In this example, the handle 410 is suspended relative to the bottom surface 422i of the baffle 420. More specifically, see Figure 7 The handle 410 is connected to the bottom surface 422i of the baffle 420 via the slope 422j on the left side of the figure. In this way, the space formed by the handle 410 hanging in the air allows the user to insert his fingers, making it easier for him to pull the buckle 400 upward. In addition, in this example, the slope 422j is a slope, but in another example, it can be a vertical slope.

[0064] In addition, see Figure 6 The handle 410 has a protruding oblique reinforcing rib 421 at two turning points of the connection part with the baffle 420 on the upper and lower surfaces in the figure to prevent the handle 410 from deforming under force when being pulled. One end of the oblique reinforcing rib 421 points to the width direction of the baffle 420, and the other end points to the outer edge of the handle 410.

[0065] As can be seen from the above-mentioned embodiments, the present disclosure provides four openings in the main body of the baffle of the fastener, and embeds a metal sheet in the main body, and exposes the anti-wear portion of the metal sheet in the opening of the locking portion. Therefore, when the snap-fitting column of the second connector is snapped into the locking portion through the anti-wear portion, which can prevent the snap-fitting column from directly rubbing against the main body, thereby effectively extending the service life of the fastener. In addition, the opening of the metal sheet is exposed in the opening of the pivoting portion, and the supporting column of the first connector component can be inserted into the opening of the metal sheet, thereby improving the wear resistance of the baffle when pivoting, and further extending the service life of the fastener.

[0066] Although the present disclosure has been disclosed as above by way of embodiments, it is not intended to limit the present disclosure. Anyone with ordinary knowledge in this technical field can make various changes and modifications without departing from the spirit and scope of the present disclosure. Therefore, the protection scope of the present disclosure shall be determined by the scope of the patent application.
