Description

Technical Field

[0001] The utility model relates to the technical field of electronic assembly, and more specifically to a technology for providing power connection for a printed circuit board (hereinafter referred to as "PCB board"), and in particular to a connector assembly for electrically connecting a cable to a PCB board. Background Art

[0002] The continuous development of new energy vehicles has led to an increasing number of high-current application scenarios for PCB boards in automotive electronic and electrical products. In response, while improving the current-carrying capacity of the power connector of the PCB board, the size and weight of the power connector have also increased, which has put forward higher requirements on the connection stability and reliability of the power connector.

[0003] In the prior art, the power connector of the PCB board usually includes a metal cable connector and a PCB board connector. Among them, one end of the cable connector is connected to the cable connected to the power supply, and the other end has a through hole; one end of the PCB board connector (also known as a "power element") includes a cylinder with an external thread, and the other end includes a plurality of pins. The pins are soldered in the corresponding pin holes on the PCB board through through-hole reflow soldering (PIP / PTH), thereby fixing the PCB board connector on the PCB board. The spiral cylinder of the PCB board connector passes through the through hole on the cable connector, and then a matching nut is screwed on to fix the cable connector on the PCB board connector. In this way, the cable connected to the power supply is electrically connected to the PCB board through the cable connector and the PCB board connector fixed to the cable connector, so that power is supplied to the PCB board from the power supply.

[0004] It has been found that the power connector of the above-mentioned existing structure for electrically connecting the cable to the PCB board has problems such as poor conductivity, easy connection loosening or even falling off, low manufacturing efficiency, high cost, etc. Utility Model Content

[0005] The purpose of the present invention is to solve at least one of the above problems and / or other defects in the prior art.

[0006] After careful research, the inventor found that one of the main reasons for the poor conductivity of the above-mentioned existing power connector is that the cable connector is sleeved on the threaded cylinder of the PCB board connector through its through hole and is clamped and fixed between the nut and the PCB board connector by screwing the nut, so that the cable connector only contacts the PCB board connector through a very limited area around its through hole, and the contact area is small, resulting in a large contact resistance, thereby affecting the conductive performance and current carrying capacity of the power connector. In addition, the cable connector is fastened to the spiral cylinder of the PCB board connector through the nut, but the torque applied when the nut is screwed is not easy to control: when the torque is too large, the welding of the pins of the PCB board connector on the PCB board is easy to loosen; and when the torque is too small, the cable connector between the nut and the PCB board connector is easy to loosen or even fall off. The above looseness makes the connection strength of the power connector low, and also causes poor conductive contact between the cable connector and the PCB board connector. Furthermore, the spiral cylinder on the PCB board connector is threaded, and the processing of the thread is laborious and time-consuming, resulting in time-consuming connector production and increased costs.

[0007] To achieve the above object, based on the above research, one aspect of the utility model provides a connector assembly for electrically connecting a cable to a PCB board, the connector assembly comprising a board-side connector connected to the PCB board and a cable-side connector connected to the cable. The board-side connector comprises a conductive element, the conductive element comprises a connecting portion connected to the PCB board and a columnar portion extending from the connecting portion, and the cable-side connector comprises a conductive sleeve connected to the cable. The inner circumference of the conductive sleeve is directly or indirectly press-fitted onto the outer circumference of the columnar portion to form a conductive connection between the conductive sleeve and the columnar portion.

[0008] According to one embodiment of the utility model, the cable side connector also includes a conductive ring interposed between the conductive sleeve and the columnar portion and capable of elastically deforming in the radial direction, and the inner circumferential surface of the conductive sleeve is indirectly press-fitted onto the outer circumferential surface of the columnar portion via the conductive ring.

[0009] According to an embodiment of the present invention, the peripheral wall of the conductive sleeve is constructed in a fence shape or a grid shape.

[0010] According to an embodiment of the present utility model, the board-side connector further comprises an insulating base, which is fixed to the connecting portion of the conductive element and is also connected to the PCB board.

[0011] According to an embodiment of the present utility model, the base is formed as a whole with the conductive element by inserting the connecting portion of the conductive element through inlay injection molding, and is fixedly mounted on the PCB board by fasteners.

[0012] According to an embodiment of the present utility model, the connecting portion of the conductive element includes a plurality of pins, and the plurality of pins pass through the bottom wall of the base so as to be fixed in corresponding pin holes of the PCB board.

[0013] According to an embodiment of the present utility model, the cable-side connector further comprises an insulating covering element, which at least partially surrounds the conductive sleeve and is connected to the base to fix the conductive sleeve on the base.

[0014] According to an embodiment of the present utility model, the covering element is formed as a whole with the conductive sleeve by inserting and injection molding with the conductive sleeve as an insert.

[0015] According to one embodiment of the utility model, the covering element includes a sleeve portion and a base portion connected to the sleeve portion, the sleeve portion surrounds a portion of the conductive sleeve and is provided with an opening for the end of the conductive sleeve for connecting to the cable to pass through, and the base portion is connected to the base.

[0016] According to an embodiment of the present invention, the base portion is detachably connected to the base via a snap mechanism.

[0017] The utility model has at least one or more of the following beneficial effects: the cable side connector of the connector assembly according to the utility model includes a conductive sleeve, and the board side connector includes a conductive element having a columnar portion. By making the inner circumference of the conductive sleeve directly or indirectly press-fit on the outer circumference of the columnar portion of the conductive element, a larger conductive contact area can be reliably formed between the conductive sleeve and the conductive element, reducing the contact resistance, and improving the conductive performance compared with the above-mentioned existing power connector connected by a spiral fastening method. Further, the use of a conductive collar disposed between the conductive sleeve and the columnar portion of the conductive element can ensure good conductive contact between them without accurately designing the tolerance matching relationship between the two. The conductive element of the board side connector is not only directly connected to the PCB board through its connecting portion (which may include multiple pins), but is also additionally fixed to the PCB board through an additional base, thereby improving the connection strength of the board side connector on the PCB board. The cable side connector can be directly fixed to the board side connector through its covering element, eliminating the risk of loose connection or falling off caused by the difficult control of torque in the spiral fastening method used in the above-mentioned existing power connector. The cable-side connector and the board-side connector do not use a spiral connection method, which avoids time-consuming and labor-intensive thread processing, thereby reducing the production difficulty and cost of the connector assembly.

[0027] Embodiments of the present invention are described below with reference to the accompanying drawings. In the following description, many specific details are set forth so that those skilled in the art can more fully understand and implement the present invention. However, it is obvious to those skilled in the art that the implementation of the present invention may not have some of these specific details. In addition, it should be understood that the present invention is not limited to the specific embodiments described. On the contrary, any combination of the features and elements described below may be considered to implement the present invention, regardless of whether they relate to different embodiments. Therefore, the following aspects, features, embodiments and advantages are for illustrative purposes only and should not be regarded as elements or limitations of the claims unless clearly stated in the claims.

[0028] In the following, terms such as "first", "second", etc. are used to describe the elements of the present application. These terms are only used to distinguish the various elements, and are not used to limit the nature, order or number of these elements. The terms "including" and "having" are used to express an open-ended inclusive meaning, and mean that there may be additional elements / components in addition to the listed elements / components.

[0029] The utility model provides a novel connector assembly for electrically connecting a cable to a PCB board, wherein the connector assembly improves the conductive performance and current carrying capacity by changing the connection mode between its parts and the connection mode between the connector assembly and the PCB board, and further strengthens the connection strength between the connector assembly and the PCB board.

[0030] The structure of the connector assembly will be described in detail below. Directional terms such as "top", "bottom", "upper" and "lower" used in the description of the present invention refer to the installation orientation of the connector assembly relative to the PCB board, that is, the side close to the PCB board is the bottom or lower part, and the side away from the PCB board is the top or upper part.

[0031] Figures 1 to 6 FIG. 2 shows a connector assembly 3 according to an embodiment of the present invention, which is used to electrically connect a cable 1 to a PCB board 2. Figure 1 and Figure 2 As shown, the connector assembly 3 according to this embodiment includes a board-side connector 31 and a cable-side connector 32 (also referred to as a “female connector”) mating with the board-side connector 31 .

[0032] The board-side connector 31 is connected to the PCB board 2 and includes a conductive element 311. The conductive element 311 includes a connecting portion 3111 and a columnar portion 3112 extending from the connecting portion 3111. The board-side connector 31 is connected to the PCB board 2 through the connecting portion 3111. More specifically, the connecting portion 3111 may include a plurality of pins 31111, which are soldered to corresponding plurality of pin holes 21 on the PCB board 2, for example, in a conventional through-hole reflow soldering manner, thereby connecting the board-side connector 31 to the PCB board 2.

[0033] The cable-side connector 32 includes a conductive sleeve 321, and is connected to the cable 1 through the conductive sleeve 321. The inner circumference of the conductive sleeve 321 is directly or indirectly press-fitted on the outer circumference of the columnar portion 3112 of the conductive element 311, so as to reliably form a conductive connection with a large contact area between the conductive sleeve 321 and the columnar portion 3112. It can be understood that the conductive element 311 here refers to a conductive element that is conductive throughout, that is, its components, including the connecting portion 3111 and the columnar portion 3112, all have conductive properties. The above-mentioned expression "directly press-fit" means that in some embodiments, the shape and radial dimension of the inner circumference of the conductive sleeve 321 and the outer circumference of the columnar portion 3112 are very close or even perfectly matched, so that the conductive sleeve 321 can be conveniently fitted on the columnar portion 3112, and the inner circumference of the conductive sleeve 321 and the outer circumference of the columnar portion 3112 can be closely contacted with a large area to conduct electricity, but this may require a complex process to accurately design and realize the tolerance matching relationship between the inner circumference of the conductive sleeve 321 and the outer circumference of the columnar portion 3112. The expression "indirectly press-fit" means that in some other embodiments, other conductive components (such as the conductive collar 322 described below) can be interposed between the conductive sleeve 321 and the columnar portion 3112, so that the conductive contact area between the conductive sleeve 321 and the columnar portion 3112 can be greatly increased through the interposed conductive components without accurately designing and manufacturing the conductive sleeve 321 and the columnar portion 3112. Regardless of which of the above-mentioned settings is used, compared with the power connector in the prior art that uses a screw fastening method for electrical connection, the connector assembly 3 in this embodiment can ensure a larger area of ​​conductive contact through the press fit between the inner circumference of the conductive sleeve 321 and the outer circumference of the columnar portion 3112, thereby reducing the contact resistance and improving the conductive performance and current carrying capacity of the connector assembly 3.

[0034] According to an exemplary embodiment of the cable-side connector 32, continue to refer to Figure 2The cable-side connector 32 may further include a conductive collar 322 disposed between the conductive sleeve 321 and the columnar portion 3112. The diameters of the bottom and top of the conductive collar 322 are slightly larger than the diameter of the middle thereof, and the conductive collar 322 is made of a conductive material having a certain elasticity, so that the conductive collar 322 has a certain elastic deformation capability in the radial direction. In this way, when the conductive collar 322 is disposed between the inner circumference of the conductive sleeve 321 and the outer circumference of the columnar portion 3112, the shape and / or size difference between the two can be absorbed or compensated, so that the inner circumference of the conductive sleeve 321 can be more tightly and reliably press-fitted on the outer circumference of the columnar portion 3112 via the conductive collar 322, thereby ensuring that there is a sufficient conductive contact area between the conductive sleeve 321 and the conductive element 311.

[0035] According to some specific embodiments of the conductive collar 322, Figure 2 and Figure 4 As shown, the peripheral wall of the conductive sleeve 322 can be constructed in a fence or grid shape, which means that there are multiple gaps in the peripheral wall of the conductive sleeve to facilitate its elastic deformation (expansion or contraction) in the radial direction to absorb or compensate for the shape and / or size differences between the inner peripheral surface of the conductive sleeve 321 and the outer peripheral surface of the columnar portion 3112, and ensure a reliable press fit and good conductive contact between them.

[0036] According to an exemplary embodiment of the board-side connector 31, Figure 2 and Figure 5 As shown, the board-side connector 31 may further include an insulating base 312, which is fixed to the connecting portion 3111 of the conductive element 311 and is also connected to the PCB board 2. In this way, the conductive element 311 can not only be connected to the PCB board 2 through the connecting portion 3111, but also be fixed to the PCB board 2 through the base 312, further increasing the connection strength between the conductive element 311 and the PCB board 2.

[0037] In order to conveniently connect the conductive element 311 to the base 312, the base 312 can be formed as a whole with the conductive element 311 by inserting the connecting portion 3111 of the conductive element 311 through insert injection molding. In this way, the connecting portion 3111 (including the portion of its pin 31111 located above the PCB board) can be wrapped in the base 312, thereby preventing dust and other impurities from the outside from contacting the pin of the conductive element 311 and affecting its conductive performance. The specific operation of insert injection molding may include setting the conductive element 311 as a whole at an appropriate position in the injection mold, and molding by injecting plastic material to wrap its connecting portion, and forming the base 312 on the outer periphery of the connecting portion 3111 after the mold is opened. The base 312 formed by injection molding may be formed with a protrusion 3121 extending to both sides, and the protrusion 3121 may be formed with a first through hole 31211 with an internal thread, for example. The PCB board 2 may be provided with a second through hole 22 corresponding to the first through hole 31211, so that the base 312 can be fixedly mounted on the PCB board 2 by a fastener 4 (such as a screw shown in the figure). In some other embodiments, the fastener 4 may also be a bolt and a nut, and the bolt passes through the second through hole 22 and the first through hole 31211 and is fastened by the nut. The fastener 4 may also be a self-tapping screw. In this case, it is not necessary to pre-form a through hole on the PCB board 2 and the protrusion 3121, but the self-tapping screw can be directly drilled through the PCB board 2 and drilled into the base 312 for fastening. It can be imagined that the base 312 is not limited to being connected and fixed to the PCB board 2 by the fastener 4, but can also be fixed to the PCB board by any other appropriate fixing method, such as being fixed to the PCB board by a snap-fit ​​method.

[0038] Figure 5 The specific structure of the base 312 of the board-side connector 31 is further shown. The base 312 may include a peripheral wall 3122 surrounding the outside of the connecting portion 3111, a top wall 3123 disposed transversely to the peripheral wall 3122 near its top, and a bottom wall 3124 disposed at the bottom of the peripheral wall 3122. The bottom wall 3124 is provided with a plurality of third through holes 31241 for the pins 31111 to pass through, the top wall 3123 is provided with a fourth through hole for the columnar portion 3112 to extend out, and the bottom wall 3124, the top wall 3123 and the side walls are arranged to form a cavity 3125 for accommodating the connecting portion 3111. Figure 5 It can be concluded that the base 312 can not only be formed directly by insert injection molding with the connecting part 3111 of the conductive element 311 as an insert, but also can be directly formed by a mold to include a first part including a top wall 3123 and a peripheral wall 3122 and a second part including a bottom wall 3124. After placing the conductive element 311 into the inner cavity of the first part, the second part can be fixed to the first part.

[0039] As described above, the plurality of pins 31111 of the connection portion 3111 of the conductive element 311 can be fixed (welded) in the corresponding pin holes 21 of the PCB board 2 after passing through the third through holes 31241 of the bottom wall 3124 of the base 312. On the basis of such conventional fixing, in combination with the method of fixing the connection portion 3111 to the PCB board 2 by the base 312, for example, by means of the fastener 4, the connection and fixing strength between the board-side connector and the PCB board 2 can be improved, which is particularly conducive to fixing the board-side connector with a larger mass.

[0040] According to a further embodiment of the cable-side connector 32, Figure 1 and Figure 2 As shown, the cable-side connector 32 further includes an insulating covering element 323. The covering element 323 can at least partially surround the conductive sleeve 321 and be connected to the base 312, thereby fixing the conductive sleeve 321 on the base 312 and maintaining the relative position of the conductive sleeve 321 and the columnar portion 3112.

[0041] With reference to the molding method of the base 312 described above, the covering element 323 can also be formed integrally with the conductive sleeve 321 by inserting and injection molding a part of the conductive sleeve 321 as an insert. Specifically, the conductive sleeve 321 can be set at a suitable position of the injection mold, and the plastic material is used to wrap only a part of the conductive sleeve 321 at the suitable position for injection molding to form the covering element 323. The other part of the conductive sleeve 321 (more specifically, the upper end) can extend out of the covering element 323 to facilitate the connection of the cable 1. It is understandable that when a conductive collar 322 is provided between the conductive sleeve 321 and the columnar portion 3112, the conductive collar 322 can also be welded to the conductive sleeve 321 to form a whole, and then the outer periphery of the conductive sleeve 321 is insert-injected.

[0042] Figure 6 FIG. 3 shows a specific structure of the covering element 323, which may include a sleeve portion 3231 and a base portion 3232. Figure 4 and Figure 6 It can be seen that the sleeve portion 3231 surrounds a portion of the conductive sleeve 321 ( Figure 4 The conductive sleeve 321 is generally provided with an opening 32311 through which the upper end of the conductive sleeve 321 passes to connect with the cable. The cable 1 can be connected to the upper end of the conductive sleeve 321 by crimping, for example. The base portion 3232 extends radially outward for a distance from the approximately middle position of the sleeve portion 3231 and extends toward the bottom of the sleeve portion 3231, thereby forming a skirt-like structure near the bottom end of the sleeve portion 3231, so as to facilitate the provision of a matching structure connected to the base 312 on the base portion 3232.

[0043] According to an exemplary embodiment of the base portion 3232, as Figure 6 As shown, the base portion 3232 can be connected to the base 312 through the guide mechanism 5 and the buckle mechanism 6. The guide mechanism 5 can ensure that the covering element 323 always moves along a certain guide track during the process of being connected to the base 312 until it abuts against the base 312, thereby ensuring that the conductive sleeve 321 and the conductive collar 322 in the covering element 323 are always in full contact with the columnar portion 3112 of the conductive element 311 in the circumferential direction. When the bottom surface of the base portion 3232 is about to abut against the top wall 3123 of the base 312, the buckle mechanism can be used to lock the two together, thereby preventing the covering element 323 from separating from the base 312, and at the same time supporting the covering element 323 through the guide mechanism 5, so as to always maintain the relative position of the covering element 323 and the base 312.

[0044] According to a specific embodiment of the guide mechanism 5 and the buckle mechanism 6, continue to refer to Figure 6 The base portion 3232 may be a frame structure with a rectangular or square cross section, and includes two first base side walls and two second base side walls arranged opposite to each other, and the guide mechanism 5 and the buckle mechanism 6 are respectively arranged on the first base side wall and the second base side wall. Correspondingly, the peripheral wall 3122 of the base 312 includes a first base side wall and a second base side wall corresponding to the first base side wall and the second base side wall, respectively. The guide mechanism 5 is arranged between the first base side wall and the second base side wall, and the buckle mechanism 6 is arranged between the second base side wall and the second base side wall, which is conducive to keeping the covering element 323 and the base 312 at two opposite positions. In some other embodiments, the cross sections of the base portion 3232 and the base 312 may also be circular or other shapes, and the guide mechanism 5 and the buckle mechanism 6 may be arranged at intervals along the circumference of the base portion 3232 and the base 312, respectively, and the guide mechanism 5 and the buckle mechanism 6 may also be combined into a structure that can provide both guiding and locking functions.

[0045] More specifically, for example, the guide mechanism 5 may include a guide post 51 and a guide groove 52, wherein the guide post 51 is arranged on one of the base portion 3232 or the base 312, and the guide groove 52 is arranged on the other. The guide post 51 slides in the guide groove 52, providing a fixed moving track for the base portion 3232 to abut against the base 312. The buckle mechanism 6 may, for example, include an elastic buckle 62 and a buckle hole 61. The elastic buckle 62 is arranged on one of the base portion 3232 and the base 312, the buckle hole 61 is arranged on the other, and the buckle mechanism 6 and the guide mechanism 5 are respectively arranged on different base side walls and different base side walls. When the base portion 3232 moves along the guide mechanism 5 to abut against the base 312, the elastic buckle 62 of the buckle mechanism 6 engages in the buckle hole 61, thereby locking. The elasticity of the elastic buckle 62 of the buckle mechanism 6 also makes the buckle mechanism detachable, so that the cable side connector can be removed from the board side connector.

[0046] In the above embodiment, the cable side connector 32 can be directly fixed on the base of the board side connector through the base portion of its covering element, eliminating the risk of loose connection or falling off caused by the difficult control of torque in the spiral fastening method used in the existing power connector, and also avoiding time-consuming and labor-intensive thread processing, thereby reducing the production difficulty and cost of the connector assembly.

Other embodiments of the utility model will be apparent to those skilled in the art from the practice of the utility model disclosed in this specification.
