Description

Technical Field

[0001] This utility model belongs to the field of electrical connector technology, specifically relating to a connector and connector assembly. Background Technology

[0002] Wire-to-board connectors are widely used in industries such as industrial automation, power systems, and office equipment due to their advantages such as good transmission performance and easy installation. As an emerging industry, the use and demand for wire-to-board connectors in the new energy sector are also constantly increasing. They are particularly prevalent in battery management systems.

[0003] In the new energy field, using ribbon cables instead of wire harnesses can effectively meet the requirements of lightweight and highly integrated equipment. Corresponding wire-to-board connectors are also widely popular due to their compact size.

[0004] However, many price-sensitive sectors, such as energy storage systems and low-end automobiles, still rely on more economical cable connection methods. Currently, cables are connected to wire-to-board connectors via crimping. This results in connectors with larger mating ends and greater height compared to ribbon cable solutions. This clearly hinders the development of lighter and more integrated circuit systems. While there are many products on the market that have implemented thinner designs for wire-to-board connectors, these optimized connectors still use screw or rivet connections at the board end. Although the connection is secure, the installation space required is still large, and installation and removal are cumbersome. Alternatively, a tab-type connection can be used, where fixed tabs are inserted into both sides of the connector and bent for fixation. However, the connection strength of the tabs is poor, and under external loads, the solder joints between the connector and the circuit board still bear a significant force. Summary of the Invention

[0005] To address the shortcomings of the prior art, this utility model provides a connector and connector assembly. By inserting a fixing member into the first housing and snapping the fixing member to the base, the thickness of the connector and the volume of the insertion end are reduced while ensuring connection strength. This achieves a lightweight and integrated effect for the wire-to-board connector in the cable solution. At the same time, its installation and disassembly efficiency is higher, and its production and maintenance costs are lower.

[0006] The technical effects to be achieved by this utility model are realized through the following technical aspects:

[0007] In a first aspect, this utility model provides a connector disposed on a circuit board, the connector comprising a first housing and a fixing member;

[0008] The first housing includes a pair of first side portions arranged opposite each other in the transverse direction, and a first end portion and a second end portion arranged opposite each other in the longitudinal direction. The first side portions are provided with support blocks and mounting grooves.

[0009] The fastener includes a bent component and a first fixing block and a second fixing block disposed at both ends of the bent component. The first fixing block is inserted into the mounting groove, the bent component abuts against the support block, and the second fixing block is elastically connected to the first side. The second fixing block is provided with a first locking block.

[0010] The circuit board is mounted on the base, which is provided with a support arm. The second fixing block is connected to the support arm by the first locking block, thereby connecting the connector and the base together.

[0011] In some implementations, the first housing has a positioning block extending toward the base on the first side, the base has a positioning groove, and the positioning block is inserted into the positioning groove.

[0012] In some implementations, the first housing further includes a bottom and a top disposed along the height direction, the bottom, the top, the second end and the first side portions on both sides forming an opening receiving cavity, and the first locking block being disposed on the side of the second fixing block away from the receiving cavity;

[0013] The second fixing block is bent at its end to form a guide block, and the guide block is disposed on the side of the second fixing block near the receiving cavity;

[0014] The support arm is provided with a first slot, and the first locking block is snapped into the first slot.

[0015] In some implementations, the connector further includes a first terminal, one end of which is soldered to the circuit board, and the other end of which extends into the receiving cavity from the second end.

[0016] In some implementations, the bent component has a C-shaped or U-shaped structure, and the length of the second fixing block is greater than the length of the first fixing block;

[0017] The second fixing block is provided with a pressing boss, the protrusion height of which is equal to or less than the protrusion height of the first locking block.

[0018] The distance between the first card block and the bottom is greater than the distance between the bottom surface of the positioning block and the bottom.

[0019] In some implementations, the first side is further provided with a limiting block, the limiting block protruding toward the second fixing block, and there is a gap between the limiting block and the second fixing block.

[0020] Secondly, this utility model provides a connector assembly, comprising:

[0021] The connector described above, and

[0022] The mating connector is inserted into the connector via the first end.

[0023] In some implementations, the mating connector includes:

[0024] The second housing includes a pair of second sides arranged opposite each other in the lateral direction, and a plug-in end and a wiring end arranged opposite each other in the longitudinal direction, wherein the wiring end is connected to a cable;

[0025] A first seal surrounds the insertion end; and

[0026] The second seal encloses the cable and is embedded in the terminal of the connector.

[0027] In some implementations, the second side is provided with a lever arm, which is located outside the plug-in end, and the lever arm is provided with a second slot;

[0028] The first side has a second locking block near the first end, and the second locking block is snapped into the second slot.

[0032] 2. The connector provided by this utility model adopts a fixing method with a second fixing block that is elastically set and a first locking block that is connected to the support arm by a snap-fit. While ensuring the performance, compared with the existing wire-to-board connectors that use screws, rivets or inserts, its installation and disassembly efficiency is higher and its production and maintenance costs are lower.

[0033] 3. The connector assembly provided by this utility model can achieve a high degree of integration close to that of ribbon cables when using cables to connect to the circuit board, thus solving the problem that it is impossible to make the connector smaller and thinner when using cable solutions.

[0057] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.

[0058] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0059] Example 1:

[0060] Please see Figures 1-2 This embodiment provides a connector 100, including a first housing 1 and a fixing member 2. By inserting one side of the fixing member 2 into the first housing 1 and then snapping the other side into the base 300 below the circuit board 200, the connector 100 is stably fixed on the circuit board 200.

[0061] For ease of subsequent explanation and understanding, we hereby clarify that the movement direction along the X-axis in the figure is horizontal, the movement direction along the Y-axis is vertical, and the movement direction along the Z-axis is the height direction or the up-down direction.

[0062] For details, please refer to Figures 1-3The first housing 1 includes a pair of first side portions 11 arranged opposite each other in the transverse direction, and a first end portion 12 and a second end portion 13 arranged opposite each other in the longitudinal direction. The first side portion 11 is provided with a support block 111 and a mounting groove 112.

[0063] There are two fixing components 2, including a bent component 21 and a first fixing block 22 and a second fixing block 23 disposed at both ends of the bent component 21. The first fixing block 22 is inserted into the mounting groove 112, the bent component 21 abuts against the support block 111, and the second fixing block 23 is elastically connected to the first side 11. The second fixing block 23 is provided with a first locking block 231.

[0064] The circuit board 200 is mounted on the base 300, and the base 300 is provided with a support arm 301. The second fixing block 23 is connected to the support arm 301 by the first locking block 231, thereby connecting the connector 100 and the base 300 together.

[0065] The circuit board 200 is sandwiched between the connector 100 and the base 300 like a sandwich, ensuring the connection strength between the connector 100 and the circuit board 200. When plugging and unplugging with a matching cable connector, the force generated during the plugging and unplugging process will not affect the circuit soldering between the connector 100 and the circuit board 200.

[0066] Compared to existing cable connectors, the connector 100 described in this embodiment can be made smaller in height and volume at the plug end on the circuit board 200, eliminating the need for a larger volume to provide the connection structure and space, unlike screw and riveting connections. Furthermore, compared to existing insert-type fixing solutions, the connector 100 described in this embodiment offers superior connection strength, effectively ensuring the stability of the electrical connection between the cable and the circuit board 200.

[0067] Of course, besides making the connector end smaller and thinner, since the fixing member 2 is plugged into and fixed to the first housing 1, the fixing member 2 and the first housing 1 form a whole. Then, it is connected to the support arm 301 by the first locking block 231. The connector 100, circuit board 200 and base 300 can be quickly fixed or disassembled. Compared with the fixing method of screws and other fasteners, it is more efficient and has a lower production cost. Compared with the plug-in type fixing method, the connector 100 structure can be replaced without damaging it during maintenance and replacement, which greatly reduces maintenance costs.

[0068] Furthermore, the first housing 1 has a positioning block 116 extending toward the base 300 on its first side 11. The base 300 has a positioning groove 302, and the positioning block 116 is inserted into the positioning groove 302. In this embodiment, the positioning block 116 is a "U"-shaped structure surrounding the second fixing block 23, and a portion of the positioning groove 302 matches the shape of the "U"-shaped positioning block 116. By engaging the positioning block 116 with the positioning groove 302, the lateral and longitudinal positions between the first housing 1 and the base 300 are precise. This ensures that the snap-fit ​​connection between the first locking block 231 and the support arm 301 meets design requirements and ensures consistency in mass production. Of course, the "U"-shaped structure is only one of the preferred solutions; in other embodiments, the positioning block 116 can also be a "T"-shaped structure or an "L"-shaped structure.

[0069] exist Figures 1-3 Based on this, refer to Figures 4-5 In some embodiments, the first housing 1 further includes a bottom 14 and a top 15 disposed along the height direction. The bottom 14, top 15, second end 13, and first side portions 11 on both sides surround to form a receiving cavity 16 with an opening. The opening of the receiving cavity 16 communicates with the first end 12 to form a plug-in structure. Therefore, in actual installations, the first end 12 is often disposed at the edge of the circuit board 200 to facilitate the plug-in mating of the connector 100 and the mating connector for cable connection.

[0070] In this embodiment, the first locking block 231 is disposed on the side of the second fixing block 23 away from the receiving cavity 16. The second fixing block 23 is bent at its end to form a guide block 232, which is disposed on the side of the second fixing block 23 near the receiving cavity 16. The support arm 301 is provided with a first locking groove 3011, and the first locking block 231 is snapped into the first locking groove 3011. As... Figure 2 As shown, the first slot 3011 is located on the inner side of the support arm 301. The first locking block 231, with an inverted triangular clearance structure, is located on the side of the second fixing block 23 away from the receiving cavity 16, so that the first locking block 231, along with the elastic second fixing block 23, avoids the support arm 301 and enters into the first slot 3011. The guide block 232 further facilitates the advance clearance of the second fixing block 23. During insertion, the guide block 232 guides the second fixing block 23 in advance, allowing the first locking block 231 to be engaged with the first slot 3011 without pressing the second fixing block 23.

[0071] In a further embodiment, the connector 100 also includes a first terminal 3, one end of which is soldered to the circuit board 200, and the other end extends from the second end 13 into the receiving cavity 16. When the mating connector at the cable end is inserted into the receiving cavity 16, the cable is indirectly electrically connected to the circuit board 200 through the first terminal 3, thereby achieving the electrical connection effect of the connector 100. Of course, in order to further reduce the height and overall volume of the connector 100, this embodiment has two rows of first terminals 3, one above the other, and the first terminals 3 in the upper row and the lower row are staggered at the soldering position on the circuit board 200, arranged in a straight line. In order to achieve the staggered arrangement and increase the creepage distance, the first terminals 3 in the upper and lower rows are bent at different angles at the second end 13. Figure 6 The left side of the image shows the first terminal 3 in the top row, and the right side shows the first terminal 3 in the bottom row.

[0072] Furthermore, the bent component 21 has a C-shaped or U-shaped structure, and the length of the second fixing block 23 is greater than the length of the first fixing block 22. In this embodiment, the opening of the bent component 21 faces downward, which ensures that the fixing component 2 accurately abuts against the support block 111, thereby ensuring an accurate and stable snap-fit ​​connection between the first locking block 231 and the first locking groove 3011. Figure 7 As shown, the second fixing block 23 is provided with a pressing boss 233, the protrusion height of which is equal to or less than the protrusion height of the first locking block 231. With the pressing boss 233 provided, the position of the second fixing block 23 becomes more obvious, and its position can be quickly located and pressed. In practical applications, to ensure a stable and effective latching connection of the first locking block 231, the first slot 3011 should have sufficient depth to accommodate the first locking block 231, meaning the first locking block 231 will enter the space of the first slot 3011. The provision of the pressing boss 233, with its protrusion height equal to or less than the protrusion height of the first locking block 231, ensures that the first locking block 231 is securely locked after installation and also avoids the possibility of the first locking block 231 disengaging from the first slot 3011 due to misoperation.

[0073] In this embodiment, the distance between the first locking block 231 and the bottom 14 is greater than the distance between the bottom surface of the positioning block 116 and the bottom 14. In the height direction, the positioning block 116 is already inside the positioning groove 302 before the first locking block 231 is engaged with the first locking groove 3011, thus achieving a connection effect of positioning first and then locking. Furthermore, since the distance between the first locking block 231 and the bottom 14 is greater than the distance between the bottom surface of the positioning block 116 and the bottom 14, the spacing between the first locking groove 3011 and the positioning groove 302 is sufficient, thereby ensuring the structural strength of the support arm 301 at that location.

[0074] like Figure 8As shown, to ensure that the second fixing block 23 does not lose its elasticity due to excessive deformation during installation or disassembly, the first side 11 is also provided with a limiting block 113. The limiting block 113 protrudes towards the second fixing block 23, and a gap 114 is provided between the limiting block 113 and the second fixing block 23. When the operator applies pressure to the second fixing block 23, the first locking block 231 will gradually disengage from the support arm 301 during the elastic deformation of the second fixing block 23. Under normal circumstances, the first locking block 231 will disengage from the support arm 301 before the second fixing block 23 abuts against the limiting block 113, and the connector 100 can then disengage from the circuit board 200 and the base 300.

[0075] In summary, the connector provided by this utility model fixes the first fixing block to the mounting groove and the bent part to the support block, thus fixing the fixing part to the first housing. Then, the first locking block is snapped into the support arm, securing the connector to the circuit board. Compared to existing cable-to-board connectors, this design reduces the connector thickness and the volume of the plug-in end while maintaining connection strength, achieving a lightweight effect for cable-based cable-to-board connectors.

[0076] In addition, the second fixing block with flexible setting and the fixing method of setting the first locking block and the support arm to be connected by a buckle, while ensuring the use effect, have higher installation and disassembly efficiency and lower production and maintenance costs compared with the existing wire-to-board connectors that use screws, rivets or inserts.

[0077] Example 2:

[0078] Please Figures 1-8 Based on the above, refer to Figures 9-12 This embodiment provides a connector assembly 400, including the connector 100 from embodiment 1 and a mating connector 4 that matches the connector 100. The mating connector 4 is inserted into the connector 100 via a first end 12. One end of the mating connector 4 is connected to a cable 4131, and the other end is inserted into the connector 100, thereby achieving an electrical connection between the cable 4131 and the circuit board 200.

[0079] Specifically, the mating connector 4 includes a second housing 41, a first seal 42, and a second seal 43. The second housing 41 includes a pair of second side portions 411 disposed laterally opposite each other, and a plug end 412 and a wiring end 413 disposed longitudinally opposite each other, the wiring end 413 being connected to a cable 4131. The first seal 42 is disposed around the plug end 412, while the second seal 43 wraps around the cable 4131 and is embedded in the wiring end 413.

[0080] In use, the plug end 412 is inserted into the first end 12 to connect the mating connector 4 and the connector 100. After insertion, the outer side of the first seal 42 abuts against the inner surface of the receiving cavity 16 for sealing, while the inner side wraps and seals against the outer surface of the plug end 412, thereby isolating the connection position of the mating connector 4 and the connector 100 from the external space, preventing possible liquid ingress, and avoiding the risk of short circuit. A second seal 43 is provided at the connection position of the wiring end 413 and the cable 4131 to further restrict liquid from seeping into the receiving cavity 16 from the cable 4131.

[0081] Furthermore, please... Figures 9-11 Based on the above, refer to Figure 12 The second side portion 411 is provided with a lever arm 4111, which is located outside the insertion end 412, and the lever arm 4111 is provided with a second slot 41111. The first side portion 11 is provided with a second locking block 115 near the first end 12, and the second locking block 115 is snapped into the second slot 41111. When the insertion end 412 is inserted into the receiving cavity 16 of the first end 12, the mating connector 4 is snapped into the connector 100 by the lever arm 4111 and the second locking block 115, thereby locking and fixing the two together.

[0082] Specifically, the lever arm 4111 has a symmetrical "seesaw" structure, with its middle part connected to the second side part 411 to form a fulcrum. A button 41112 is provided on the side facing the wiring end 413, while a second slot 41111 is provided on the side facing the first side part 11. When the plug end 412 is inserted into the first end 12, the second locking block 115 pushes up the edge of the second slot 41111 and falls into the second slot 41111. When unlocking and disengaging the mating connector 4 and the connector 100, by pressing the button 41112 and simultaneously pulling the connector 100 and the mating connector 4 in the opposite direction, the second slot 41111 and the second locking block 115 are unlocked and disengaged, and then the plug end 412 is separated from the first end 12.

[0083] In some embodiments, considering that the second housing 41 is mostly made of materials such as rubber and plastic with good insulation properties, the maximum allowable elastic deformation is relatively low. To prevent the lever arm 4111 from breaking beyond its limit during assembly, a second limiting block 4112 is provided on the side of the second side 411 facing the button 41112. Figure 9 As shown, when unlocking the mating connector 4 and connector 100, pressing button 41112 until button 41112 abuts against the second limit block 4112 will not cause lever arm 4111 to exceed the limit of elastic deformation of its material, thereby improving the service life of lever arm 4111.

[0084] In summary, the connector assembly provided by this utility model can achieve a high degree of integration close to that of ribbon cables when using cables to connect to the circuit board, thus solving the problem that cable solutions cannot be made smaller and thinner.

[0085] Example 3:

[0086] This embodiment, based on embodiment 2, provides a connector assembly 400. Please refer to... Figures 1-12 Based on this, refer to Figures 13-14 Unlike the connector assembly 400 in Embodiment 2, the mating connector 4 further includes a second terminal 44, which is electrically connected to the first terminal 3. One end of the first terminal 3 is soldered to the circuit board 200 for electrical connection, and the other end is in contact with the second terminal 44. The second terminal 44 is electrically connected to the cable 4131 within the insertion end 412. Through the electrical contact connection between the first terminal 3 and the second terminal 44, a detachable connection between the cable 4131 and the circuit board 200 is achieved.

[0087] In some embodiments, to further reduce the height of connector 100 and mating connector 4, the second terminal 44 is inserted into the first terminal 3 via a lateral point contact, thereby reducing the height dimension of the second terminal 44 during molding.

[0088] In other embodiments, the mating connector 4 is further provided with a terminal lock 45, and each second terminal 44 is provided with a terminal hole 441 that matches the terminal lock 45. On the row of second terminals 44, the terminal lock 45 is inserted into the corresponding terminal hole 441 to achieve a locking and fixing effect on the second terminals 44 within the second housing 41. Compared to the existing solution that uses a spring-loaded structure on the second terminals 44 and a locking hole on the second housing 41, its height and overall volume will be further reduced, achieving a higher wiring density in the connector assembly 400.
