Description

Technical Field

[0001] The utility model relates to the technical field of connectors, and particularly relates to an electrical connector. Background Art

[0002] In the prior art, in order to realize the electrical connection between a connector and a circuit board, there are two common solutions. One solution is to connect the circuit board through a cable extended from the connector. This method requires setting up a cable and welding the cable to the circuit board, with a complex structure and low connection efficiency. Another solution is to set up a plug-in connector on the circuit board and directly plug the contact of the connector into the plug-in connector. Although the connection efficiency is improved, the installation difficulty of this method is large, and the position accuracy requirements for the contact and the plug-in connector are high. It is very difficult to plug successfully if there is a slight deviation in alignment. Summary of the Utility Model

[0025] 1. By setting the watch band contact finger to be inserted and connected with the contact piece and the watch band contact finger to be translatable and slidable within the base, the floating insertion connection between the contact piece and the adapter can be achieved, improving the tolerance ability of the insertion connection to the relative positions of the two and reducing the difficulty of the insertion connection; by setting the base to include a first support surface and a second support surface arranged in parallel, the watch band contact finger can be slidably clamped between the first support surface and the second support surface, and the movement path of the watch band contact finger can be limited between the two support surfaces, reducing the shaking of the watch band contact finger in the vertical direction and further ensuring the accuracy of the insertion connection between the contact piece and the watch band contact finger; by providing a receiving cavity below the first support surface and the second support surface, after the contact piece penetrates through the first support surface, the second support surface and the watch band contact finger and extends into the receiving cavity, the contact area between the contact piece and the adapter can be increased, improving the reliability of their connection.

[0026] 2. By setting the watch band contact finger to penetrate through the second support surface and extend into the receiving cavity, the watch band contact finger arranged in this way can guide the contact piece, facilitating the contact piece to quickly insert into the watch band contact finger and then extend into the receiving cavity. In addition, by the axial extension setting of the watch band contact finger, the axial contact area between the contact piece and the watch band contact finger can be increased, improving the connection reliability.

[0027] 3. By setting the part of the watch band contact finger passing through the second support surface to be in clearance fit with the second opening of the second support surface, a movement space can be provided for the watch band contact finger to slide within the second opening, further ensuring that the contact piece can achieve floating insertion connection with the adapter.

[0028] 4. By setting the second end of the watch band claw to be elastically deformable under an external force, and when the diameter of the contact piece cylinder is greater than the minimum inner diameter of the insertion opening surrounded by the watch band claw, further setting the inner diameter of the insertion opening surrounded by the second end to be smaller than the inner diameter of the insertion opening surrounded by the first end, the contact piece can smoothly pass through the insertion opening surrounded by the first end and enter the insertion opening surrounded by the second end, and the outer wall of the contact piece can be in close contact with the insertion opening surrounded by the second end, increasing the connection firmness.

[0029] 5. By setting the assembly direction of the contact piece and the insulating housing and the insertion direction of the contact piece and the adapter to be opposite, the adverse influence of the latter assembly on the fixed position or fixed structure of the former assembly can be minimized.

[0060] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0061] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present invention, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0062] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0063] The supplementary description of the accompanying drawings is as follows: Figure 2 Corresponding to Figure 1 the position where the connector rotates 90 degrees in Figure 14 and Figure 15 shows different processes of the contact member being inserted into the adapter. Embodiment 1

[0064] As Figure 1 and Figure 2As shown in the figure, the present utility model provides a connector (100), which includes an insulating housing (110) and a contact member (120) installed inside the insulating housing (110). The connector further includes an adapter (200) fixed on a circuit board (300), and the adapter (200) is electrically connected to the circuit board (300). An installation cavity (111) is provided on one side of the insulating housing (110) close to the circuit board (300). One end of the contact member (120) is located inside the installation cavity (111). The adapter (200) and the insulating housing (110) are on the same side of the circuit board (300), that is, both the adapter and the insulating housing are located above the circuit board. At least a part of the adapter (200) extends into the installation cavity (111) to be plugged and connected with the contact member (120). The connector of the present utility model is an MC4 male connector. It can be understood that the connector can also be an MC4 female connector. Among them, the contact member is a metal conductor, usually made of copper material.

[0065] By setting it in the above way, the installation cavity can provide preliminary positioning for the plugging of the contact member and the adapter, so as to improve the alignment accuracy during the plugging process. In addition, by extending a part of the structure of the adapter into the installation cavity to directly plug and connect with the contact member, the axial length of the contact member can be shortened, making the overall structure of the connector simple and the layout compact, effectively saving the installation space required for the connection between the connector and the circuit board.

[0066] As Figure 1 shown, the distance between the end of the contact member (120) close to the circuit board (300) and the circuit board (300) is not less than the distance between the bottom of the insulating housing (110) and the circuit board (300), that is, the distance between the end of the contact member (120) close to the circuit board (300) and the circuit board (300) is greater than the distance between the bottom of the insulating housing (110) and the circuit board (300), or the distance between the end of the contact member (120) close to the circuit board (300) and the circuit board (300) is equal to the distance between the bottom of the insulating housing (110) and the circuit board (300). Such a setting can limit the contact member to be located in the installation cavity of the insulating housing, further shortening the axial length of the contact member. In this embodiment, the distance between the end of the contact member (120) close to the circuit board (300) and the circuit board (300) is greater than the distance between the bottom of the insulating housing (110) and the circuit board (300). Here, the distance refers to the distance along the axis of the contact member, ensuring that the contact member is completely located inside the insulating housing.

[0067] As Figure 1 and Figure 2As shown, the insulating housing (110) overlaps with the adapter (200) axially, and the contact member (120) overlaps with the adapter (200) axially. Such an arrangement can ensure that at least part of the structure of the contact member can extend into the adapter to achieve the plug-in connection between the contact member and the adapter. The ratio of the length of the overlapping part of the contact member (120) and the adapter (200) axially to the height of the adapter (200) ranges from 1 / 4 to 3 / 4. When the height ratio is within this range, the connection reliability between the contact member and the adapter can be ensured. When the ratio is greater than 3 / 4, the probability of the contact member colliding with the bottom of the adapter increases, and the force generated by the collision may have an adverse impact on the circuit board or the contact member. When the ratio is less than 1 / 4, the axial contact length between the contact member and the adapter is small, and the plug-in connection is unstable, and there may be a risk of loosening. In this embodiment, the ratio of the length of the overlapping part of the contact member (120) and the adapter (200) axially to the height of the adapter (200) is 1 / 2. Selecting this ratio can obtain an ideal connection effect.

[0068] As Figure 1 and Figure 2 shown, the projection of the insulating housing (110) on the circuit board (300) covers the projection of the adapter (200) on the circuit board (300), and the whole adapter can be extended into the insulating housing to minimize the axial distance between the contact member and the adapter, thereby shortening the length of the contact member and minimizing the axial length of the contact member.

[0069] As Figure 3 and Figure 5 shown, the bottom of the insulating housing (110) is provided with positioning studs (112), and the circuit board (300) is provided with positioning holes (310) corresponding to the positioning studs. The cooperation between the positioning studs and the positioning holes can position the installation position of the connector on the circuit board to facilitate the alignment and plug-in connection between the contact member and the adapter.

[0070] Specifically, the positioning stud (112) includes a first stud (1121) and a second stud (1122) arranged coaxially. The first stud (1121) is located on the side of the positioning stud (112) close to the circuit board (300). The first stud (1121) has a clearance fit with the positioning hole (310), and the diameter of the second stud (1122) is larger than the diameter of the positioning hole (310). Such an arrangement can not only facilitate the alignment and cooperation between the first stud and the positioning hole, but also prevent the bottom of the insulating housing from directly contacting the surface of the circuit board, preventing damage or wear to the surface structure of the circuit board. The height of the second stud (1122) is less than the height of the adapter (200), which can control the gap between the bottom of the insulating housing and the circuit board within a reasonable height range to ensure that at least part of the adapter extends into the insulating housing. Among them, the length of the first stud can be set to be less than or equal to the depth of the positioning hole so that the first stud is completely located within the positioning hole.

[0071] In other alternative solutions, an elastic buffer structure is provided at the bottom of the insulating housing (110). By providing the elastic buffer structure, the acting force generated during the insertion process of the connector and the adapter can be buffered, reducing the direct acting force of the insulating housing on the circuit board. It can be understood that the elastic buffer structure can also exist simultaneously with the positioning studs, and the two are spaced apart and distributed at the bottom of the insulating housing, which can achieve the positioning and buffering effects simultaneously.

[0072] As Figure 4 shown, a seal (400) is provided between the insulating housing (110) and the contact member (120). The seal (400) is in interference fit with both the insulating housing (110) and the contact member (120). Such a setting can achieve the sealing between the internal contact member and the insulating housing of the connector, and can achieve the waterproof and dustproof effects inside the connector even when the connector is not docked and mated with other connectors. In this embodiment, the seal is an O-ring.

[0073] In other alternative solutions, the seal (400) is integrally injection-molded with the contact member (120) and then installed into the insulating housing (110), and the seal (400) is in interference fit with the insulating housing (110). Such a setting can also achieve the waterproof and dustproof effects inside the connector.

[0074] In this embodiment, the connector is used in a photovoltaic inverter. The assembly direction of the insulating housing (110) and the inverter housing (500) is opposite to the insertion direction of the contact member (120) and the adapter (200); the assembly direction of the contact member (120) and the insulating housing (110) is opposite to the insertion direction of the contact member (120) and the adapter (200). By setting the two assembly directions to be opposite respectively, the adverse effects of the latter assembly on the fixed position or fixed structure of the former assembly can be minimized.

[0075] Specifically, as Figure 1 and Figure 2 shown, the inverter housing (500) is provided with a mounting hole (510). The insulating housing (110) penetrates the mounting hole (510) from the inside to the outside of the inverter and is fixed in cooperation with a nut (130) outside the inverter housing (500). The insulating housing (110) includes a mounting boss (113) that abuts against the housing beside the mounting hole (510). A gasket (600) is provided between the mounting boss (113) and the inner side surface of the inverter housing (500). The insulating housing (110) further includes a thread (114) adjacent to the mounting boss (113). The nut (130) is fixedly connected to the thread (114) to fix the connector on the inverter housing.

[0076] As Figure 6 andFigure 8 As shown, a side of the nut (130) away from the mounting hole (510) is provided with an assembly groove (132) that cooperates with the assembly tool, and a plurality of assembly grooves are evenly distributed along the circumference of the nut. By providing the assembly grooves on the nut, it is convenient for assemblers to use the assembly tool to easily install and remove the nut.

[0077] like Figure 7 and Figure 8 As shown, a first anti-loosening protrusion (115) is provided on the insulating housing (110), and a second anti-loosening protrusion (131) is provided on the nut (130). The second anti-loosening protrusion (131) is aligned with the first anti-loosening protrusion (115), and the height of the first anti-loosening protrusion (115) is less than the height of the thread (114), and the height of the second anti-loosening protrusion (131) is greater than the height of the thread (114). By setting the first anti-loosening protrusion and the second anti-loosening protrusion that cooperate with each other, an anti-loosening effect can be generated after the nut and the thread on the insulating housing are tightened, and the height of the first anti-loosening protrusion (115) is set to be less than the height of the thread (114) to avoid blocking the nut from being screwed into the thread.

[0078] like Figure 9 、 Figure 10 and Figure 13 As shown, the adapter (200) includes a base (210) and a watchband contact finger (220), and the watchband contact finger (220) has an insertion interface (223) for plugging with the contact member (120). When the contact member (120) and the watchband contact finger (220) are plugged in, the watchband contact finger (220) can slide in the base (210) along a direction perpendicular to the insertion direction of the contact member (120). This arrangement can achieve floating plug-in connection between the contact member and the adapter, reduce the difficulty of plug-in connection, and improve installation efficiency.

[0079] Specifically, if Figures 9 - 13 As shown, the base (210) includes a first supporting surface (211) and a second supporting surface (212) arranged in parallel, and the strap contact finger (220) is slidably clamped between the first supporting surface (211) and the second supporting surface (212), so that the strap contact finger (220) can slide and translate in the base (210), and a first opening (2111) corresponding to the plug interface (223) is provided on the first supporting surface (211).

[0080] By setting the watch band contact finger to be inserted and connected with the contact piece and the watch band contact finger to be translatable and slidable within the base, a floating insertion connection between the contact piece and the adapter can be achieved, improving the tolerance ability of the insertion connection to the relative positions of the two and reducing the difficulty of the insertion connection; by setting the base to include a first support surface and a second support surface arranged in parallel, and the watch band contact finger can be slidably clamped between the first support surface and the second support surface, the movement path of the watch band contact finger can be limited between the two support surfaces, reducing the shaking of the watch band contact finger in the vertical direction and further ensuring the accuracy of the insertion connection between the contact piece and the watch band contact finger.

[0081] Furthermore, as Figure 1 and Figure 9 shown, the base (210) further includes a receiving cavity (213) located below the first support surface (211) and the second support surface (212). The contact piece penetrates through the first support surface (211), the second support surface (212) and the watch band contact finger (220) and then extends into the receiving cavity (213). By providing a receiving cavity below the first support surface and the second support surface, the contact piece penetrates through the first support surface, the second support surface and the watch band contact finger and then extends into the receiving cavity, which can increase the contact area between the contact piece and the adapter and improve the reliability of their connection.

[0082] As Figure 9 and Figure 10 shown, the watch band contact finger (220) penetrates through the second support surface (212) and then extends into the receiving cavity (213). The watch band contact finger arranged in this way can guide the contact piece, facilitating the contact piece to quickly extend into the receiving cavity after being inserted into the watch band contact finger. In addition, by the axial extension setting of the watch band contact finger, the contact area between the contact piece and the watch band contact finger in the axial direction can be increased, improving the connection reliability.

[0083] In addition, as Figure 14 and Figure 15 shown, the part of the watch band contact finger (220) passing through the second support surface (212) is in clearance fit with the second opening (2121) of the second support surface (212). Such a setting can provide a movement space for the watch band contact finger to slide within the second opening, further ensuring that the contact piece can achieve a floating insertion connection with the adapter.

[0084] As Figures 9 - 11As shown, the accommodation cavity (213) is formed by a first side support surface (2131) extending downward from the first support surface (211), a second side support surface (2132) extending downward from the second support surface (212), and a bottom support surface (2133) formed by the first side support surface (2131) and the second side support surface (2132) extending towards the center and intersecting. The first support surface (211), the second support surface (212), and the accommodation cavity (213) are integrally bent and formed from a metal material. The first support surface (211) and the second support surface (212) are fixedly connected through a plurality of pairs of snap structures (2134) extending from their respective edges. Specifically, there are 4 pairs of snap structures, which are distributed between the first side support surface (2131) and the second side support surface (2132). The snap structure includes a card slot formed by bending the first support surface downward and a hook extending outward from the second support surface. The hook cooperates with the card slot to fix the first support surface and the second support surface.

[0085] As Figures 9 - 10 and Figures 12 - 13 shown, the watch band finger (220) includes a watch band plate (221) and a plurality of watch band claws (222). The watch band claws (222) are inserted and cooperated with the contact member (120). The watch band plate (221) is located between the first support surface (211) and the second support surface (212) in parallel, and the distance between the first support surface (211) and the second support surface (212) is greater than the thickness of the watch band plate (221). A plurality of watch band plate protrusions (2211) are provided on the top surface of the watch band plate (221). The watch band plate protrusions (2211) are in contact with the bottom of the first support surface (211), and the bottom surface of the watch band plate (221) is in contact with the top of the second support surface (212).

[0086] As Figure 14 and Figure 15 shown, one end of the contact member (120) close to the adapter (200) is a cylinder (121) with a chamfered corner. The diameter of the cylinder (121) is greater than the minimum inner diameter of the insertion opening surrounded by a plurality of watch band claws (222). As Figures 12 - 13 shown, the watch band claws (222) are integrally formed with the watch band plate (221), and the watch band claws (222) are located in the middle of the watch band plate (221). The watch band claws (222) include a first end (2221) connected to the watch band plate (221) and a second end (2222) extending downward from the first end (2221). The second end (2222) can be elastically deformed under an external force, and the inner diameter of the insertion opening surrounded by the second end (2222) is smaller than the inner diameter of the insertion opening surrounded by the first end (2221).

[0087] By setting the second end of the watch band claw to be elastically deformable under an external force, and when the diameter of the contact member cylinder is greater than the minimum inner diameter of the insertion opening surrounded by the watch band claws, further setting the inner diameter of the insertion opening surrounded by the second end to be smaller than the inner diameter of the insertion opening surrounded by the first end, it is possible to enable the contact member to smoothly pass through the insertion opening surrounded by the first end and enter the insertion opening surrounded by the second end, and to enable the outer wall of the contact member to be in close contact with the insertion opening surrounded by the second end, thereby increasing the connection firmness.

[0088] As Figure 14 and Figure 15 shown, the specific process of the floating plug connection between the contact member and the adapter is described as follows:

[0089] When the axis of the contact member does not coincide with the axis of the watch band finger (the axis of the watch band finger coincides with the axis of the first support surface), and the horizontal distance between the axis of the contact member and the axis of the watch band finger is within a certain numerical range, the cylinder of the contact member extends into the first opening of the adapter. At this time, the contact member does not extend into the insertion opening, but contacts the connection between the watch band claw and the watch band plate. While the contact member continues to move downward, it drives the watch band finger to slide horizontally, and the cylinder of the contact member then extends into the insertion opening, and then squeezes the watch band claw to deform, passes through the second end of the watch band claw, and enters the accommodation cavity of the adapter, completing the floating plug connection process.

[0090] As Figure 16 shown, a temperature sensor (700) is provided on the contact member (120). Specifically, an installation groove is provided at the end of the contact member close to the circuit board, and the temperature sensor is installed in the installation groove. And in the assembled state, the end with the temperature sensor extends into the adapter. Such a setting enables the temperature sensor to be close to both the contact member and the adapter at the same time, and can timely sense the temperature changes of both.

[0091] In other alternative solutions, as Figure 17 shown, a temperature sensor (700) is provided on the base (210) of the adapter. Specifically, a temperature sensor is provided on a side support surface of the adapter. The temperature sensor can be installed outside the adapter as shown, and it can be understood that the temperature sensor can be installed inside the adapter. Such a setting can make full use of the accommodation cavity space of the adapter.

[0092] As Figure 18As shown, several adapters (200) are provided on the circuit board (300). A number of contacts (120) are inserted and mated with the several adapters (200) one by one. Each watch band finger (220) can slide in the corresponding base (210) along a direction perpendicular to the insertion direction of the contact (120). Specifically, two connectors are shown in the figure, one is a male connector and the other is a female connector. When the two connectors are inserted into the adapter downward at the same time, the two contacts move downward, and the watch band fingers in the corresponding adapters below are driven to slide horizontally as needed, so that the two contacts can be quickly inserted and mated with the watch band fingers respectively.

[0093] In other alternative solutions, a through hole (2136) for the contact (120) to pass through is provided at the bottom of the accommodation cavity (213). An elastic structure or an avoidance hole (320) corresponding to the position of the through hole (2136) is provided on the circuit board (300). By providing the elastic structure or the avoidance hole, the protruding contact can be buffered or avoided, preventing the contact from directly contacting the circuit board. Embodiment 2

[0094] As Figure 19 shown, the adapter (200) and the insulating housing (110) are located on the same side of the circuit board (300), that is, both the adapter and the insulating housing are located on the upper side of the circuit board. The adapter is fixed and electrically connected to the upper surface of the circuit board. The contact (120) protrudes from the insulating housing (110) to be inserted and connected with the adapter (200). The nut is screwed tightly with the thread on the insulating housing inside the inverter housing to fix the connector on the inverter housing. Embodiment 3

[0095] As Figure 20 shown, the adapter (200) and the insulating housing (110) are located on different sides of the circuit board (300), that is, the adapter is located below the circuit board and the insulating housing is located above the adapter. An avoidance hole (320) for the contact (120) to pass through is provided on the circuit board (300). The contact (120) passes through the avoidance hole (320) and is inserted and connected with the adapter (200). Such a setting can make full use of the space below the circuit board to install the adapter.

[0096] In other alternative solutions, a through hole (2136) for the contact (120) to pass through is provided at the bottom of the accommodation cavity (213). Embodiment 4

[0097] As Figure 21 and Figure 22As shown, the adapter (200) is provided with welding pins (2135). There are multiple welding pins (2135), which are evenly arranged on the bottom support surface at the bottom of the accommodation cavity (213). The adapter (200) is fixedly welded to the circuit board (300) through the welding pins (2135). The contact member (120) is located inside the insulating housing (110). The adapter (200) extends into the insulating housing (110) and is plugged into the contact member (120).

[0098] In other alternative solutions, such as Figure 23 As shown, the adapter (200) is fixed to the circuit board through the welding pins at the bottom. The contact member (120) extends out of the insulating housing (110) to be plugged into the adapter (200).

[0099] In other alternative solutions, the welding pins (2135) are arranged on the first support surface (211), and the adapter (200) is installed below the circuit board (300) through the welding pins (2135).

[0100] The above are only the preferred embodiments of the present invention, and do not limit the patent protection scope of the present invention. Any equivalent structural transformation made by using the description and drawings of the present invention under the inventive concept of the present invention, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
