Description

Technical Field

[0001] This invention relates to the field of electrical connector technology, and in particular to a connector and connector assembly with a floating function. Background Technology

[0002] As electronic devices become smaller and denser, higher demands are placed on the installation accuracy and connection reliability of connectors. When multiple connectors are used side-by-side or in arrays, factors such as board-to-board installation errors and thermal expansion and contraction can easily lead to mating difficulties or poor contact. Traditional fixed connectors are unable to compensate for these deviations, which may cause signal transmission interruptions or equipment damage.

[0003] Furthermore, existing floating connectors mostly employ a unidirectional elastic structure, limiting their floating range. When multiple connectors are mated simultaneously, uneven force can easily damage the terminals. Board-to-board connections require high-current power supply, high-current conversion, and high-current connection conversion between multiple functional modules, placing higher demands on the power supply current between boards. Therefore, a connector structure capable of multi-directional floating and stable transmission of high current is needed. Summary of the Invention

[0004] The purpose of this application is to overcome the shortcomings of the prior art and provide a connector and connector assembly that achieves multi-directional floating by optimizing the terminal structure and housing fit, thereby improving connection reliability and current transmission capability.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: a connector for inserting and connecting a plurality of mating connecting parts arranged in a specific order; the connector includes:

[0006] A fixed housing is fixed to the circuit board, and its interior surrounds a receiving cavity;

[0007] A movable housing is mounted in the receiving cavity in such a way that it can float and shift relative to the fixed housing in a plane parallel to the circuit board, and has a plug-in hole for inserting and removing mating connection components.

[0008] Several sets of power terminal units are arranged in an array on the circuit board, which elastically support the movable housing within the receiving cavity of the fixed housing;

[0009] Each power terminal unit includes at least two symmetrically arranged elastic terminals, each elastic terminal having a conductive body for current flow, and the conductive body having at least one pair of elastic contact arms for electrical connection with mating connection components.

[0010] The elastic terminal includes a conductive body fixed inside the movable housing, an elastic contact arm integrally bent towards the insertion hole along the bottom end of the conductive body and protruding into the insertion hole, and a fixing part bent towards the insertion hole side along the vertical direction of the conductive body. The conductive body extends along the width direction of the movable housing to form a floating support arm, and an end conductor provided at the free end of the floating support arm. The upper end of the end conductor is fixed to the fixed housing, and the lower end is fixed to the circuit board. Each elastic contact arm forms an elastic contact part that contacts the mating connection component.

[0011] When each power terminal unit includes a pair of elastic terminals symmetrically arranged along the transverse central axis of the plug hole, the transverse central axis is used as the dividing line, and a second connection part is provided between the end conductors of the two elastic terminals on the same side. The pair of elastic terminals symmetrically arranged along the transverse central axis of the plug hole has a roughly U-shaped structure, and the corresponding 8 elastic contact arms of the two power terminal units are in close contact with each mating connection component.

[0012] Furthermore, the floating support arm is either straight or curved. When the floating support arm is curved, it is provided with one or more elastic curved sections, and the bending direction of the elastic curved sections is perpendicular to the extension direction of the floating support arm.

[0013] Furthermore, the elastic contact arm includes at least a first contact arm and a second contact arm. The first contact arm is provided with a first elastic contact portion, and the second contact arm is provided with a second elastic contact portion. When the mating connection component is inserted into the insertion hole, the first contact arm and the second contact arm located on both sides of the mating connection component undergo elastic deformation, and the second elastic contact portion contacts the mating connection component before the first elastic contact portion.

[0014] Furthermore, it also includes multiple grounding terminals, the upper end of which is mounted on a fixed housing, and the lower end of which is fixed on a circuit board.

[0015] The present invention also provides a connector assembly comprising a connector as described above and a mating connector, wherein the mating connector comprises a base plate, a mating housing fixed on the base plate, a plate-shaped mating connection component disposed on the mating housing, and a grounding component, wherein the mating connection component is electrically connected to a plurality of elastic terminals.

[0016] Furthermore, the mating housing includes mating support columns located at the four corners, and a pair of long side structures and a pair of short side structures connected between each mating support column. The height of the short side structure in the insertion direction is greater than the height of the mating support column, and the height of the long side structure in the insertion direction is less than the height of the mating support column.

[0017] The fixed housing includes support columns at the four corners, and a pair of first side structures arranged along the width direction and a pair of second side structures arranged along the length direction connected between each support column. The height of the first side structure in the insertion direction is less than the height of the support column, and the height of the second side structure in the insertion direction is greater than the height of the support column.

[0018] When the connector is mated with the mating connector, a first floating gap is provided between the short side structure and the support post, so that the mating connector can slide relative to the connector in the width direction.

[0019] Furthermore, a second floating gap is provided between the second side structure and the mating support column, so that the mating connector can slide relative to the connector in the length direction.

[0020] The beneficial effects of this invention are as follows: by arranging several sets of power terminal units in an array on the circuit board, the current flow area can be increased in a limited space, while the contact area with the mating connection parts can be increased, and the temperature rise can be effectively reduced; and by setting the power terminals as elastic terminals, not only can current flow be realized, but the function of supporting the movable housing to float elastically can also be realized. Setting a floating gap between the connector and the mating connector can realize stable contact between the two connectors and realize stable signal or current transmission.

[0050] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0051] In this embodiment, the length direction of both the movable and fixed housings is defined as the X direction, and the direction perpendicular to it, i.e., the width direction of the movable or fixed housings, is defined as the Y direction. The height direction of the connector is defined as the Z direction (which is the vertical direction along the conductive body). The mounting direction of the mating connector to the connector is defined as the T direction, and the opposite direction is defined as the T' direction. Here, the T' direction is the same as the Z direction. In this embodiment, the definition of direction is relative to the posture shown in the accompanying drawings. In other postures, the definition of direction changes with the posture and is not limited here.

[0052] like Figures 1 to 3This diagram shows the overall structure and cross-sectional view of connector 1 in this embodiment. Connector 1 allows multiple mating connection components 21 arranged in an array to be inserted for connection. Connector 1 includes a fixed housing 11, which is fixed to the circuit board 10 and is generally rectangular in shape. A receiving cavity 113 opening in the Z direction is formed inside the fixed housing 11. A movable housing 12 is disposed inside the receiving cavity 113. The movable housing 12 is installed in the receiving cavity 113 in a way that it can float and shift relative to the fixed housing 11 in a plane parallel to the circuit board 10. It has mating connection components. The plug-in hole 120 is 21. A plurality of power terminal units 13 are arranged around the plug-in hole 120. The plurality of power terminal units 13 are arranged in an array on the circuit board 10. The power terminal units 13 can elastically support the movable housing 12 in the receiving cavity 113 of the fixed housing 11. Each power terminal unit 13 includes at least two elastic terminals 130 arranged symmetrically. The elastic terminal 130 has a conductive body 1300 for current flow, and the conductive body 1300 is provided with at least a pair of elastic contact arms 1301 for electrical connection with the mating connection component 21.

[0053] In this embodiment, multiple sets of power terminal units 13 are arranged to contact and electrically connect with mating connection components 21. The basic principle of this arrangement is that current flows into connector 1 from half of the parallel-connected elastic terminals 130, and is transmitted to mating connector 2 through mating connection components 21 (see below). The current then flows out from the other half of the parallel-connected power terminal units 13. This flow method is possible because in actual finished connectors, two conductive sheets (not shown in the figure) similar to copper sheets are pre-laid on the circuit board 10 in connector 1. The two conductive sheets are disconnected, for example, by combining... Figure 1 The entire circuit board is divided into two parts in the X direction, and conductive sheets are laid on the left and right sides respectively. The conductive sheets in the mating connector 2 cover the entire board 20, thereby realizing the conduction of current.

[0054] Furthermore, by setting symmetrically distributed elastic terminals 130 and at least one pair of elastic contact arms 1301 on the elastic terminals 130, multiple parallel current inflow terminals and parallel current outflow terminals can be formed, which can achieve stable contact while also enabling the flow of large current.

[0055] In a deformable embodiment, the floating support arm 1303 can be configured as a straight type (not shown in the figure) or a curved type (e.g., Figure 3 and Figure 4When the floating support arm 1303 is curved, it is provided with one or more elastic bending portions 13030. The bending direction of the elastic bending portion 13030 is perpendicular to the extension direction of the floating support arm 1303. Of course, the elastic bending portion 13030 here can be V-shaped or S-shaped. Figure 3 and Figure 4 This is just an example; its specific shape is not limited here.

[0056] like Figure 8 As shown, one embodiment is as follows: each power terminal unit 13 includes four elastic terminals 130. Each elastic terminal 130 includes a conductive body 1300 fixed inside the movable housing 12, an elastic contact arm 1301 integrally bent towards the insertion hole 120 along the bottom end of the conductive body 1300 and protruding into the insertion hole 120, a floating support arm 1303 extending from the conductive body 1300 in the Y direction, and a fixing part 1302 bent towards the insertion hole 120 along the Z direction of the conductive body 1300. The floating support arm 1303... The free end is provided with an end conductor 1304. The upper end of the end conductor 1304 is fixed to the fixed housing 11 and the lower end is fixed to the circuit board 10. The elastic contact arm 1301 forms an elastic contact portion that contacts the mating connection component 21. With the elastic terminal 130 of this structure as the basic unit, four elastic terminals 130 of this structure are arranged on the left and right sides of the plug hole 120 along the X direction, which realizes that at least eight elastic contact arms 1301 are in close contact with each mating connection component 21, increasing the contact area and current flow.

[0057] Temperature rise analysis of the inter-board power connector 1 in the above embodiment was performed, using the floating support arm 1303 as the temperature test point. When the floating support arm 1303 is bent, the temperature rise is 24.9℃ and 17.8℃ when passing 60A and 50A current, respectively; when the floating support arm 1303 is straight, the temperature rise is 24.4℃ and 17.5℃ when passing 60A and 50A current, respectively. In contrast, the temperature rise of the existing floating connector reaches 42.0℃ or 34.3℃ when passing 60A current (tested using two different terminal materials). This comparison shows that the temperature rise effect of the present connector 1 is significantly better than that of the existing connectors.

[0058] Continue to refer to Figure 8The elastic contact arm 1301 includes at least a first contact arm 13010 and a second contact arm 13012. The first contact arm 13010 is provided with a first elastic contact portion 13011, and the second contact arm 13012 is provided with a second elastic contact portion 13013. When the mating connection component 21 is inserted into the insertion hole 120, the first contact arm 13010 and the second contact arm 13012 located on both sides of the mating connection component 21 undergo elastic deformation. The second elastic contact portion 13013 contacts the mating connection component 21 before the first elastic contact portion 13011. Of course, the number of elastic contact arms 1301 can be increased according to the actual installation space, and the number is not limited here. The first contact arm 13010 and the second contact arm 13012 are not arranged in the same plane to ensure sufficient contact between the terminals of the two connectors.

[0059] Based on the above embodiment, other possible variations include: (Refer to...) Figure 7 and Figures 9-10 As shown, when each power terminal unit 13 includes a pair of elastic terminals 130 symmetrically arranged along the longitudinal central axis L1 of the insertion hole 120, a first connecting portion 131 is provided between the conductive bodies 1300 of the two elastic terminals 130 located on the left or right side of the longitudinal central axis L1.

[0060] Or refer to Figure 7 and Figures 11-12 As shown, when each power terminal unit 13 includes a pair of elastic terminals 130 symmetrically arranged along the transverse central axis L2 of the insertion hole 120, the transverse central axis L2 is used as the dividing line, and a second connecting part 132 is provided between the end conductors 1304 of the two elastic terminals on the same side. The two elastic terminals 130 symmetrically arranged along the transverse central axis L2 of the insertion hole 120 have a roughly U-shaped structure. That is to say, the connecting part will merge two adjacent elastic terminals 130 in the X direction or Y direction into a whole. This arrangement can increase the floating elasticity of the elastic terminals 130, increase the current flow cross-sectional area, ensure the stability of the foundation, and reduce the temperature rise.

[0061] Figures 5-6 The diagram shown illustrates the structure of the movable housing 12 and the fixed housing 11 before they are mounted onto the circuit board 10. Before mounting, the movable housing 12 is fixed within the receiving cavity 113 of the fixed housing 11 by multiple detachable connecting bridges 122. After mounting, the detachable connecting bridges 122 are removed, and the movable housing 12 is then supported by multiple elastic terminals 130 for elastic floating. (Refer to...) Figure 6 A symmetrical terminal mounting groove 123 is provided in the X direction of the insertion hole 120 of the movable housing 12 to accommodate the fixing part 1302 of the elastic terminal 130, so as to ensure that the elastic terminal 130 is stably installed in the movable housing 12.

[0062] Furthermore, the above embodiment also includes multiple grounding terminals 14, which are independently installed at the four corners of the fixed housing 11. Each of the four corners of the fixed housing 11 is provided with a fixing hole 1101. The upper end of the grounding terminal 14 is installed inside the fixing hole 1101, and the lower end is fixed to the circuit board 10. The fixing method here can be soldering, insertion, or other optional methods. That is to say, as long as electrical connection can be achieved, the specific connection method is not limited.

[0063] Further alternatives: such as Figures 6-7 As shown, a protruding mounting post 1110 can be provided on the first side structure 111 of the fixed housing 11, and a mounting hole 100 is provided on the corresponding circuit board 10. The mounting post 1110 is engaged in the mounting hole 100 to stably fix the fixed housing 11 on the circuit board 10.

[0064] Figures 13-18 This illustrates another embodiment of the invention:

[0065] like Figures 15-16 As shown, a connector assembly includes a connector 1 as described above and a mating connector 2. The mating connector 2 includes a base plate 20, a mating housing 22 fixed on the base plate 20, a plate-shaped mating connection member 21 disposed on the mating housing 22, and a grounding member 23. The mating connection member 21 is electrically connected to a plurality of elastic terminals 130.

[0066] Specifically, the mating housing 22 includes mating support columns 220 located at the four corners, and a pair of long side structures 222 and a pair of short side structures 221 connected between each mating support column 220. The height of the short side structure 221 in the T direction is greater than the height of the mating support column 220, and the height of the long side structure 222 in the T direction is less than the height of the mating support column 220. The fixed housing 11 includes support columns 110 located at the four corners, and a pair of first side structures 111 arranged in the Y direction and a pair of second side structures 112 arranged in the X direction connected between each support column 110. The height of the first side structure 111 in the Z (T') direction is less than the height of the support column 110, and the height of the second side structure 112 in the Z (T') direction is greater than the height of the support column 110.

[0067] like Figure 13 As shown, when connector 1 and mating connector 2 are connected, a first floating gap D1 is provided between the short side structure 221 and the support post 110, so that the mating connector 2 can slide relative to connector 1 in the Y direction. Of course, in conjunction with this, refer to... Figure 18The length of the insertion hole 120 of the movable housing 12 in the Y direction is greater than the length of the mating connecting part 21 in this direction. That is to say, there is a mating floating gap D1' between the two. The first floating gap D1 and the mating floating gap D1' are the same distance in the Y direction.

[0068] Reference Figure 14 A second floating gap D2 is provided between the second side structure 112 and the mating support column 220. In this embodiment, the part of the second side structure 112 that is higher than the support column 110 in the Z direction is an inclined structure. Correspondingly, the mating support column 220 is also set as an inclined structure. A second floating gap D2 is provided between the two inclined surfaces. Of course, it can also be set as a straight structure. No specific limitation is made here. Correspondingly, the movable housing 12 inside the connector 1 floats in the X direction by means of the floating support arm 1303, thereby allowing the mating connector 2 to slide relative to the connector 1 in the X direction.

[0069] like Figure 17 As shown, the two short side structures 221 of the mating housing 22 in the Y direction are wrapped around the outer sides of the movable housing 12 to bear part of the force, thereby preventing the connector from being damaged by excessive floating in the X direction.

[0070] Optional, such as Figures 15-16 As shown, the substrate 20 has a positioning groove 223 in the T direction, and the upper surface of the movable housing 12 has a positioning strip 121. When the connector 1 and the mating connector 2 are mated and connected, the positioning strip 121 is engaged with the positioning groove 223.

[0071] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0072] In the description of this application, unless otherwise expressly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the meaning of the above terms in this application according to the specific circumstances.

[0073] In the description of this embodiment, the terms "upper," "lower," "front," and "rear," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. The terms "first" and "second" are used only for distinction in description and have no special meaning.

[0074] The embodiments described above merely illustrate the implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
