Mode for Carrying Out the Invention

[0018] In order to more clearly illustrate the technical problems to be solved, the technical solutions adopted, and the technical effects to be achieved by the present invention, the technical solutions of the embodiments of the present invention will be described in more detail below with reference to the drawings. It should be noted that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative labor shall fall within the protection scope of the present invention.

[0019] In the description of the present invention, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed to" should be understood in a broad sense. For example, it may be a fixed connection, a removable connection, or an integral one. It may be a mechanical connection or an electrical connection. It may be directly connected or indirectly connected through an intermediate medium. It may be a communication within two elements or an interaction relationship between two elements. A person skilled in the art can understand the specific meaning of the above terms in the present invention in a specific situation.

[0020] In the present invention, unless otherwise clearly defined and limited, the fact that the first feature is "above" or "below" the second feature may include that the first feature and the second feature are in direct contact, or may include that the first feature and the second feature are not in direct contact and are in contact through another feature therebetween. Furthermore, the fact that the first feature is "above", "above the upper side", and "upper surface" of the second feature includes that the first feature is directly above or obliquely above the second feature, or simply means that the horizontal height of the first feature is higher than that of the second feature. The fact that the first feature is "below", "below the lower side", and "lower surface" of the second feature includes that the first feature is directly below or obliquely below the second feature, or simply means that the horizontal height of the first feature is lower than that of the second feature.

[0021] In related technologies, a round-bottom solder cup is used for the male terminal, but the disadvantages of a round-bottom solder cup include the following. First, a round-bottom solder cup is prone to rolling when placed, and for example, when a welding component is placed in a round-bottom solder cup, it tends to slide along the curved surface inside the round-bottom solder cup, reducing stability. The operator needs to control the position of the round-bottom solder cup more carefully, otherwise the welding position of the round-bottom solder cup may shift, making it difficult to accurately fix the pre-set welding position and potentially affecting the welding quality. Second, because the contact area between the round-bottom solder cup and the welding component is a circular area, the distribution of the welding current is uneven, making it difficult to control the uniformity of the welding. More skilled operation is required to ensure the uniformity and quality of the weld bead during the welding process. Third, for beginners, the operation difficulty of a round-bottom solder cup is relatively high, requiring more time and effort to acquire the balance and control skills, thus demanding a high level of technical proficiency from the operator.

[0022] As shown in Figures 1 to 4, an embodiment of the present invention discloses a male connector 100 comprising: a male plastic member 110 having an insertion cavity 111 with an opening 112 at one end; and a male terminal 120 having a pin head 121 and a weld end 122, connected to the male plastic member 110, the pin head 121 being drilled in the insertion cavity 111 and exposed to the outside through the opening 112, and the solder cup 123 of the weld end 122 extending from one end of the male plastic member 110 away from the opening 112 of the insertion cavity 111, the solder cup 123 being a flat-bottomed solder cup.

[0023] The insertion cavity 111 of the male connector 100 and the pin head 121 drilled in the insertion cavity 111 are used to connect to the female connector 200. The insertion cavity 111 is used to ensure the mechanical positional alignment with the female connector 200, and the pin head 121 is used to ensure the electrical connection with the female connector 200, thereby ensuring the reliability of the connection between the male connector 100 and the female connector 200. The solder cup 123 is used to connect to the welding member 300. Compared to a circular solder cup 123, the advantages of a flat-bottomed solder cup include the following: First, it has superior stability. Due to its flat-bottomed design, it can be stably positioned on the welding member 300 during the welding process, is less prone to wobbling, contributes to ensuring the correct welding position, and is particularly suitable for welding workpieces that require high positional accuracy. Next, the uniformity of the weld is excellent because the flat-bottomed solder cup can make sufficient contact with the surface of the welding member 300, resulting in a relatively uniform distribution of the welding current. This leads to a relatively uniform weld bead, and the quality of the weld bead is easier to control. Thirdly, it is easy to operate. For beginners, the flat-bottomed solder cup is easier to learn because its placement and operation are relatively simple. Therefore, by adopting a flat-bottomed solder cup, the welding stability and uniformity between the welding member 300 and the male terminal 120 are improved, and welding becomes easier.

[0024] The solder cup 123 is equipped with a welding surface 1231, which is used for contact with and welding the welding member 300. The welding surface 1231 of the flat-bottomed solder cup is flat. Specifically, the solder cup 123 has a rectangular groove, and the bottom of the rectangular groove becomes the welding surface 1231. The width of the welding surface 1231 is 1.5 to 3 times the diameter of the welding member 300. This avoids the welding surface 1231 being too narrow to be difficult to operate, and also avoids the welding surface 1231 being too wide, which would make it difficult for solder to fill the solder cup 123 and increase the amount of solder used, thus increasing costs. For example, the width of the welding surface 1231 may be 1.5, 2, 2.5, or 3 times the diameter of the welding member 300, and can be set according to the needs, but is not limited to these.

[0025] The solder cup 123 is welded to the welding member 300, and a positioning hole 124 is provided at the weld end 122 for radially positioning the welding member 300, thereby further improving the positional accuracy of the welding member 300 and the solder cup 123. The positioning hole 124 is a circular hole or a square hole, etc., and is appropriately set according to the shape of the weld.

[0026] The solder cup 123 and the weld end 122 are integrated into a single structure, improving the structural strength and reliability of the male terminal 120, while also facilitating easier manufacturing and molding. The male terminal 120 is made of a highly conductive material, ensuring stable electrical connection performance.

[0027] The male terminal 120 and the male plastic member 110 are mutually regulated in position along the extending direction of the male terminal 120, thereby improving the stability of the male terminal 120 and the male plastic member 110 and preventing the male terminal 120 from rattling in its extending direction. In one embodiment, a position regulating base 125 is provided on the outer circumference of the male terminal 120, which is regulated in position by a position regulating groove 113 provided on the male plastic member 110, thereby simplifying the structure and ensuring reliability. The male plastic member 110 is injection molded from an insulating material and provides structural support and electrical isolation. Specifically, the male terminal 120 and the male plastic member 110 may be manufactured using an insert injection molding process, or the male plastic member 110 may be divided into two parts and injection molded, the male terminal 120 and the male plastic member 110 may be assembled together, and the two divided parts of the male plastic member 110 may be connected by a removable connection or by welding or the like.

[0028] The male connector 100 further includes a locking portion 130 that extends from one end of the male plastic member 110, where the opening 112 is located, and is used to lock with the female connector 200. The mechanical lock ensures a firm and secure connection and prevents loosening. Since the female connector 200 does not structurally overlap with the male connector 100 in order to achieve the lock with the male connector 100, the thickness of the male connector 100 can be effectively reduced.

[0029] In one embodiment, the male connector 100 is connected to one side of the male plastic member 110 and further comprises a connecting plate 140, one end of which extends from the end of the male plastic member 110 having an opening 112, and which is provided with a locking portion 130. By providing the connecting plate 140, the locking portion 130 extends from one end of the male plastic member 110 via the connecting plate 140, and thereby the locking portion 130 is used to lock with the side surface of the female connector 200. Preferably, the connecting plate 140 has a certain elastic deformation capability, and when connecting the male connector 100 and the female connector 200, the connecting plate 140 is lifted by elastic deformation during the connection process, preventing interference with the female connector 200, and after the male connector 100 and the female connector 200 are fully connected, the connecting plate 140 returns to its original position to achieve locking with the female connector 200. Preferably, the locking portion 130 is a locking claw provided on the side surface of the connecting plate 140, and a locking groove that engages with the locking claw is provided on the side surface of the female connector 200, and the locking of both is achieved by the engagement of the locking claw and the locking groove. In other embodiments, the locking portion 130 may be provided on the end face of the male plastic member 110, for example, the locking portion 130 is an insertion block provided on the end face of the male plastic member 110, and by inserting it into an insertion hole provided on the end face of the female connector 200, the insertion hole and the insertion block are tightened and fitted together, and the locking of the male connector 100 and the female connector 200 is achieved.

[0030] The first end face 114 of the male plastic member 110, which has an opening 112, is flat, and the end face of the female connector 200 facing the male plastic member 110 is the second end face, which is also flat. When the female connector 200 and the male connector 100 are brought into contact, the first end face 114 and the second end face are in close contact, eliminating any gaps, preventing wobbling, and improving the reliability and stability of the connection.

[0031] In one embodiment, the welded member 300 is a cable, and the solder cup 123 of the male terminal 120 is welded to the wire core 310 of the cable.

[0032] As shown in Figures 5 to 9, this embodiment provides a female connector comprising a female plastic member 210 having a first plastic member 211 and a second plastic member 212 connected to each other, a terminal body 221, and insertion portions 222 and connecting heads 223 provided at both ends of the terminal body 221, the insertion portion 222 being used for insertion with the male terminal 120, the connecting head 223 being used for connection with the welding member 300, the terminal body 221 being sandwiched and fixed between the first plastic member 211 and the second plastic member 212, and the insertion portion 222 being located on the outside of the female plastic member 210, and a female terminal 220.

[0033] The terminal body 221 is attached to either the first plastic member 211 or the second plastic member 212. Subsequently, the second plastic member 212 and the first plastic member 211 are connected, and the terminal body 221 is sandwiched and fixed between the first plastic member 211 and the second plastic member 212, thereby achieving a fixed connection between the terminal body 221, the first plastic member 211, and the second plastic member 212. The first plastic member 211 and the second plastic member 212 form a female plastic member 210 by a removable connection, and the terminal body 221 is sandwiched and fixed between the first plastic member 211 and the second plastic member 212. Because the three are detachable, it is easy to repair defective products, and if the structure of the terminal body 221, the first plastic member 211, or the second plastic member 212 is damaged, it can be replaced, thus reducing production costs. Since the insertion portion 222 of the terminal body 221 is located on the outside of the female plastic member 210, the entire inspection can be completed with a simple visual inspection, resulting in high inspection efficiency and low cost.

[0034] The first plastic member 211 and the second plastic member 212 are connected by insertion, making them easy to attach and detach. In one embodiment, the first plastic member 211 is provided with a first clamping portion 2111 and an insertion groove 2112 along the extending direction of the female terminal 220, and the second plastic member 212 is provided with a second clamping portion 2121 and an insertion base 2122 along the extending direction of the female terminal 220, and the first plastic member 211 and the second plastic member 212 are inserted together by inserting the insertion base 2122 and the insertion groove 2112, and the female terminal 220 further comprises a fixing portion 224, which is connected between the terminal body 221 and the connecting head 223, and the fixing portion 224 is clamped and fixed between the insertion base 2122 and the insertion groove 2112, and the terminal body 221 is clamped and fixed between the first clamping portion 2111 and the second clamping portion 2121. The insertion groove 2112 and insertion base 2122 are located on one side of the female plastic member 210 along the extending direction of the female terminal 220 and are used to clamp the fixing portion 224 of the female terminal 220. The fixing portion 224 is secured by making full use of the structure of the insertion base 2122 and insertion groove 2112, and an increase in the volume of the female plastic member 210 along the other direction is avoided, resulting in a compact structure and a miniaturized design.

[0035] The first clamping portion 2111 and the second clamping portion 2121 are used to restrict the position of the terminal body 221 radially by forming a position-regulating hole 213 that fits the terminal body 221, and the position-regulating hole 213 and the terminal body 221 are interlocked. Exemplarily, the cross-section of the terminal body 221 is circular, and the first clamping portion 2111 and the second clamping portion 2121 form a circular position-regulating hole 213. The position-regulating hole 213 can be a circular hole, a rectangular hole, or a hole of any other regular or irregular shape, as long as it fits the shape of the terminal body 221, and is not limited to such shapes. Preferably, the first clamping portion 2111 and the second clamping portion 2121 are each provided with grooves, and the grooves of the two clamping portions both form a position-regulating hole 213, and the size and shape of both grooves are all the same, or the grooves of the two grooves are different.

[0036] The insertion groove 2112 and insertion base 2122 form a position regulating hole 213 that fits the fixed part 224 and are used to radially restrict the position of the fixed part 224, and the position regulating hole 213 and the fixed part 224 are interlocked. For example, if the cross-section of the fixed part 224 is rectangular, the insertion groove 2112 and insertion base 2122 form a rectangular hole, and not only can the fixed part 224 be radially restricted, but circumferential position restriction can also be achieved. The position regulating hole 213 can be a circular hole, a rectangular hole, or a hole of other regular or irregular shape, as long as it fits the shape of the fixed part 224, and is not limited to these. Preferably, the insertion groove 2112 and insertion base 2122 are each provided with a groove, and both grooves form a position regulating hole 213, and the size and shape of the two grooves are all the same, or the two grooves are different. Preferably, a groove is provided in either the insertion groove 2112 or the insertion base 2122. For example, the insertion base 2122 has a groove, and the groove in the insertion base 2122 and the end face of the insertion groove 2112 surround a position regulating hole 213. In one embodiment, as shown in Figure 6, the insertion base 2122 has a partial groove, the insertion groove 2112 has two small protruding blocks, the remaining part of the groove is formed between the two small protruding blocks, and the two parts of the groove surround a position regulating hole 213 for fitting with the fixing part 224.

[0037] Preferably, the insertion groove 2112 and the insertion base 2122 are connected by a method such as adhesive bonding, further improving the reliability of the connection. The contact surface between the insertion groove 2112 and the insertion base 2122 is an arc-shaped surface, which facilitates insertion and removal connections.

[0038] The female plastic member 210 is provided with a positioning structure, which is used to position the female terminal 220 along the extending direction of the female terminal 220, thereby improving structural accuracy. In one embodiment, the female terminal 220 includes a connecting portion 225 and a fixing portion 224, and the insertion portion 222, terminal body 221, connecting portion 225, fixing portion 224 and connecting head 223 are provided in that order. The positioning structure is a positioning base 2123 provided on the second plastic member 212, and the sides of the positioning base 2123 are in contact with the terminal body 221 and the fixing portion 224, that is, the terminal body 221, connecting portion 225 and fixing portion 224 form a positioning groove 226, and the sides of the positioning base 2123 are in contact with the two side walls of the positioning groove 226, thereby making full use of the structural features of the female terminal 220 itself to perform positioning. Preferably, the positioning base 2123 includes a first positioning portion 2124 and a second positioning portion 2125 provided at a distance from each other, the first positioning portion 2124 abutting against the terminal body 221 and the second positioning portion 2125 abutting against the fixing portion 224, thereby reducing weight, and the positioning base 2123 and the positioning groove 226 are interlocked, and the two first positioning portions 2124 and the second positioning portion 2125 can deform appropriately in their respective directions to elastically abut the terminal body 221 and the fixing portion 224, thereby making the connection stronger and further strengthening the connection between the female plastic member 210 and the female terminal 220. Furthermore, the heights of the first positioning section 2124 and the second positioning section 2125 are different and can be set to suit the terminal body 221 and the fixing section 224. For example, if the height of the first positioning section 2124 is smaller than the height of the second positioning section 2125, and the height of the terminal body 221 is larger than the height of the fixing section 224, then the first positioning section 2124 and the terminal body 221, and the second positioning section 2125 and the fixing section 224 can come into contact with each other.

[0039] The insertion portion 222 comprises at least two elastic sheets 2221, which are arranged in an annular shape, and the male terminal 120 is inserted between the at least two elastic sheets 2221. The elastic sheets 2221 elastically contact the outer circumference of the male terminal 120, and the insertion of the elastic sheets 2221 and the male terminal 120 facilitates insertion and removal, and reduces the possibility of damage during insertion and removal.

[0040] In one embodiment, the connecting head 223 of the female terminal 220 is a solder cup 123, specifically a flat-bottomed solder cup or a round-bottomed solder cup.

[0041] The female terminal 220 is made of a highly conductive material, ensuring stable electrical connection performance.

[0042] The first plastic member 211 and the second plastic member 212 of the female plastic member 210 are both injection-molded from an insulating material, providing structural support and electrical isolation.

[0043] As shown in Figure 10, this embodiment discloses a connector assembly including the female connector 200 described above and a male connector 100 that is inserted into the female connector 200. The connector assembly employs the female connector 200 described above, and because the female connector 200 is easy to inspect and repair, has a high yield rate, and low cost, the yield rate of the connector assembly is improved and costs are reduced.

[0044] As shown in Figure 10, this embodiment discloses a connector assembly including a female connector 200 and the male connector 100 described above which is inserted into the female connector 200. The connector assembly employs the male connector 100 described above, and welding of the male connector 100 to the welding member 300 is easy, improving the welding stability between the welding member 300 and the male terminal 120, further improving the welding stability between the connector assembly and the welding member 300, and making welding to the welding member 300 easier, thereby satisfying the requirements for connection stability and ease of installation of the connector assembly by smart home appliances and the like.

[0045] As shown in Figures 1 to 10, this embodiment discloses a connector assembly including the female connector 200 and the male connector 100 described above, which combines the advantages of the female connector 200 and the male connector 100, and will not be described again here.

[0046] The female connector 200 comprises a female plastic member 210 and a female terminal 220, and the male connector 100 comprises a male plastic member 110 and a male terminal 120. The male terminal 120 is provided with an insertion cavity 111, and the male terminal 120 is drilled into the insertion cavity 111. The female terminal 220 extends from the female plastic member 210, and the female terminal 220 is inserted into the insertion cavity 111, and the insertion portion 222 and the pin head 121 are inserted, and the end faces of both the female plastic member 210 and the male plastic member 110 are in close contact. The female plastic member 210 and the male plastic member 110 are in close contact facing each other, and are in contact without extrapolation. In this way, the outer dimensions of the male connector 100 are not increased by the extrapolation of the female plastic member 210, and the thickness of the combined connector is effectively reduced.

[0047] In one embodiment, the male connector 100 further includes a locking portion 130, which extends from one end of the male plastic member 110 having an opening 112, and a mating locking portion 214 is provided on the side of the female plastic member 210. The locking portion 130 and the mating locking portion 214 are locked together, mechanically locking the device and ensuring a firm and secure connection between the male connector 100 and the female connector 200. The locking portion 130 may be designed to be lower, further reducing the overall thickness of the connector assembly. In another embodiment, the locking portion 130 of the male connector 100 is provided on the side of the male plastic member, and the mating locking portion 214 of the female connector 200 extends from one end of the female plastic member 210 and locks with the locking portion 130. Furthermore, one of the locking portion 130 and the mating locking portion 214 is provided with an engaging hook, and the other is provided with an engaging groove, and locking is achieved by the engagement of the two.

[0048] The insertion portion 222 comprises at least two elastic sheets 2221, which are arranged in an annular shape, and the male terminal 120 is inserted between the at least two elastic sheets 2221. The cavity walls of the insertion cavity 111 restrict the position of the elastic sheets 2221, so that the elastic sheets 2221 elastically contact the outer circumference of the male terminal 120, thereby clamping the male terminal 120. The positional restriction between the cavity walls of the insertion cavity 111 and the elastic sheets 2221 increases the force acting between the insertion cavity 111 and the elastic sheets 2221, which can prevent the insertion portion 222 from sliding out of the insertion cavity 111. Furthermore, since the insertion portion 222 is located inside the insertion cavity 111, and the cavity walls of the insertion cavity 111 restrict the position of the elastic sheet 2221, even if a part of the structure of the insertion portion 222 slips out of the insertion cavity 111 in an unexpected situation, the cavity walls of the insertion cavity 111 restrict the position of the part of the elastic sheet 2221 located inside the insertion cavity 111, thereby achieving clamping of the male terminal 120 and ensuring high reliability.

[0049] Furthermore, the elastic sheet 2221 has a curved arc shape, with the middle section of the elastic sheet 2221 in contact with the male terminal 120, and the tip is flared to facilitate insertion and mating with the male terminal 120.

[0050] The pin head 121 extends from the opening 112 to facilitate insertion and mating with the female terminal 220.

[0051] First protruding blocks 115 are provided on both sides of the male plastic member 110, and second protruding blocks 215 are provided on both sides of the female plastic member 210. The first protruding blocks 115, the second protruding blocks 215, and the sides of the female plastic member 210 and the male plastic member 110 form grooves for mating with the external structure, further improving the reliability of assembly between the connector assembly and the external structure.

[0052] Of course, the above embodiments of the present invention are merely for illustrative purposes to clarify the examples given herein and do not limit the embodiments of the present invention. Those skilled in the art can make further variations and modifications based on the above description. There is no need or method to cover all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of the claims.
