Floating electric connector group capable of performing three-axis motion and micro motion

Abstract

The utility model discloses a floating electric connector group capable of performing three-axis micro motion, which is mainly characterized in that a first Z-axis limiting piece and a second Z-axis limiting piece are respectively arranged on a first shell and a second shell of a female end electric connector and a male end electric connector, and a Y-axis gap and an X-axis gap are kept between the first Z-axis limiting piece and the second Z-axis limiting piece; besides, the flat plate parts of the plate-shaped terminals of the female end electric connector are parallel to the XY plane, and the width of the flat plate parts is not smaller than the width of the elastic arms of the elastic terminals of the male end electric connector, so that when the first shell and the second shell perform relative micro-motion on the X axis or the Y axis, the flat plate parts of the plate-shaped terminals are still in contact with the elastic arms of the elastic terminals, and the elastic arms of the elastic terminals are in contact with the elastic arms of the elastic terminals. When the first shell and the second shell move slightly relative to each other on the Z axis, the elastic arm of each elastic terminal is contacted with the flat plate part of the corresponding plate-shaped terminal, and the contact state is still kept.

Description

Technical Field

[0001] This utility model relates to an electrical connector assembly, and more particularly to a floating electrical connector assembly capable of three-axis micro-motion. Background Technology

[0002] like Figure 7A and Figure 7B As shown, an existing electrical connector assembly has a female electrical connector 50 comprising a first housing 51 and multiple resilient terminals 53. One side of the first housing 51 is recessed to form multiple parallel slots 52. The resilient terminals 53 are fixed within the first housing 51 and correspond to the slots 52 respectively. The two elastic arms 531 of each resilient terminal 53 protrude from the two opposing inner walls 521, 522 of its corresponding slot 52. Each slot 52 penetrates the top surface 511 and bottom surface (not shown) of the first housing 51. The male electrical connector 60 of the same electrical connector assembly comprises a second housing 61 and multiple single-pole terminals 62. The single-pole terminals 62 are fixed to the second housing 61, and the front portion 621 of each single-pole terminal 62 protrudes from the front side 611 of the second housing 61. The width 12 of the front portion 621 matches the opening width W1 of each slot 52 of the female electrical connector 50, but the length L2 is slightly less than the depth D1 of each slot 52.

[0003] Since there is no other protective structure between the front portions 621 of the single-pole terminals 62 of the male electrical connector 60, when the male electrical connector 60 is not aligned and inserted into the female electrical connector 50 along the Y-axis, the front portions 621 of the single-pole terminals 62 are easily misaligned and mistakenly inserted into the slot 52, resulting in some of the front portions 621 of the single-pole terminals 62 being skewed.

[0004] This electrical connector assembly can also be used as a floating electrical connector. However, since the front part 621 of each single-pole terminal 62 matches the opening of its corresponding slot 52, it can only provide micro-movement of the Z and Y axes, and cannot micro-move the X axis. Therefore, the use of this floating electrical connector is limited. Utility Model Content

[0005] Given that existing electrical connector assemblies are prone to misalignment during insertion and that floating electrical connector assemblies can only provide two-axis micro-motion, thus limiting their application, the purpose of this utility model is to provide a floating electrical connector assembly that can perform three-axis micro-motion.

[0006] The main technical means used to achieve the above objectives is to make the floating electrical connector assembly capable of three-axis micro-motion include:

[0007] A female electrical connector, comprising:

[0008] A first housing includes an accommodating space penetrating the top surface, bottom surface, and front side surface of the first housing; a plurality of first slots penetrating the rear side surface of the first housing and communicating with the accommodating space; and a first Z-axis limiting member formed within the accommodating space; and

[0009] Multiple plate-shaped terminals are respectively inserted into the first slots of the first housing, and the flat plate portion of each plate-shaped terminal is parallel to the XY plane and partially protrudes from the receiving space; and

[0010] A male electrical connector, selectively inserted into the female electrical connector, and comprising:

[0011] A second housing, fitted and accommodated within the accommodating space of the first housing, and including a plurality of second slots extending through the front and rear sides of the second housing, and a second Z-axis limiting member corresponding to the first Z-axis limiting member of the first housing; wherein a Y-axis gap and an X-axis gap are maintained between the first Z-axis limiting member and the second Z-axis limiting member; and

[0012] Multiple elastic terminals are respectively inserted into the second slot, and the elastic arm of each elastic terminal protrudes from its corresponding second slot and contacts the plate portion corresponding to the plate-shaped terminal, and the first width of the plate portion is not less than the second width of the elastic arm.

[0013] The X-axis gap and the Y-axis gap both fall within the contact range between the elastic terminal and its corresponding plate-shaped terminal.

[0014] The first Z-axis limiting member includes two protrusions that extend laterally from two opposing inner walls of the accommodating space. The second Z-axis limiting member includes two recesses corresponding to the two protrusions. The X-axis depth of each recess is greater than the X-axis width of its corresponding protrusion, and the Y-axis depth of each recess is greater than the Y-axis length of its corresponding protrusion, thus forming the X-axis gap. The Z-axis depth of each recess matches the Z-axis height of its corresponding protrusion, thus forming the Y-axis gap.

[0015] The upper and front surfaces of each protrusion are flush with the top and front sides of the first housing, respectively, but the bottom surface is not flush with the bottom surface of the first housing; and the two recesses are formed at the two corners of the front side of the second housing, that is, each recess is recessed from the top surface, the rear side and an outer side of the second housing.

[0016] The front side of the second housing further forms an elongated groove that connects to the second slot, the opening height of the elongated groove matching the thickness of the flat plate portion of the plate terminal; and after the male electrical connector is inserted into the female electrical connector, each plate terminal is inserted into the corresponding second slot and the elongated groove.

[0017] The pin portion of each plate-shaped terminal is exposed on the rear side of the first housing and bent downward; and the outer connecting portion of each elastic terminal protrudes from the rear side of the second housing.

[0018] The pin portion of each plate-shaped terminal is exposed on the rear side of the first housing and bent downward; and the outer connecting portion of each elastic terminal protrudes from the rear side of the second housing.

[0019] Each of the elastic terminals is a vertical tuning fork with two elastic arms that are positioned opposite each other. The two elastic arms are in contact with the upper and lower surfaces of the flat plate portion of the corresponding plate terminal, respectively.

[0020] Each of the elastic terminals is a vertical tuning fork with two elastic arms that are positioned opposite each other. The two elastic arms are in contact with the upper and lower surfaces of the flat plate portion of the corresponding plate terminal, respectively.

[0021] The bottom surface of the first outer shell forms an indentation facing upwards in response to the accommodating space; and the front side surface and the bottom surface of the second outer shell extend forward with a baffle to extend into the indentation.

[0022] As described above, the floating electrical connector assembly of this utility model mainly provides corresponding first and second Z-axis limiting members for the first and second housings, and the first and second Z-axis limiting members maintain a Y-axis gap and an X-axis gap, allowing the first and second housings to move slightly relative to each other along the XYZ axes. In addition, the flat plate portion of the plate-shaped terminal of the female electrical connector is parallel to the XY plane, and its first width is not less than the second width of the elastic arm of the elastic terminal of the male electrical connector. Therefore, when the first and second housings move slightly relative to each other along the X-axis or Y-axis, the flat plate portion of each plate-shaped terminal still maintains contact with the elastic arm of the elastic terminal. As for the first and second housings moving slightly relative to each other along the Z-axis, since the elastic arm of each elastic terminal contacts the flat plate portion corresponding to the plate-shaped terminal, it also maintains contact. Therefore, the floating electrical connector assembly of this utility model can indeed provide a three-axis micro-motion function.

[0055] This utility model is a floating electrical connector assembly. The technical content of the utility model will be explained in detail below with reference to the embodiments and drawings.

[0056] Please refer to the following first. Figure 1 As shown, this is an embodiment of the floating electrical connector group 1 of the present invention, which includes a female electrical connector 10 and a male electrical connector 30; the floating electrical connector group 1 can be used for board-to-board electrical connectors.

[0057] Please refer to the following: Figure 2 As shown, the aforementioned female electrical connector 10 includes a first housing 11 and a plurality of plate-shaped terminals 20. The first housing 11 includes an accommodating space 110 penetrating the top surface 14, bottom surface 15 and front side surface 12 of the first housing 11, a plurality of first slots 111 penetrating the rear side surface 13 and communicating with the accommodating space 110, and a first Z-axis limiting member 16 formed in the accommodating space 110; wherein the first slots 111 are laterally spaced side by side. In one embodiment, the first Z-axis limiting member 16 includes two protrusions 161 and 162, which extend laterally from the two opposing inner walls 112 of the accommodating space 110. The upper and front planes of each protrusion 161 and 162 are flush with the top surface 14 and the front side surface 12 of the first outer shell 11, respectively, but their bottom planes are not flush with the bottom surface 15 of the first outer shell 11. From a top view, the first outer shell 11 is generally C-shaped. Furthermore, the bottom surface 15 forms an inwardly recessed portion 17 corresponding to the accommodating space 110, such as... Figure 5 As shown.

[0058] The plate-shaped terminals 20 of the aforementioned female electrical connector 10 are respectively inserted into the first slots 111 of the first housing 11, and partially protrude from the receiving space 110, for example... Figure 5 As shown, the flat plate portion 21 of each plate terminal 20 is parallel to the XY plane, while the pin portion 22 of each plate terminal 20 is exposed on the rear side 13 of the first housing 11 and bent downward.

[0059] like Figure 1 , Figure 2 , Figure 3B and Figure 3C As shown, the aforementioned male electrical connector 30 includes a second housing 31 and a plurality of resilient terminals 40. The second housing 31 is fitted into the receiving space 110 of the first housing 11 and includes a plurality of second slots 311 penetrating the front side 32 and rear side 33 of the second housing 31, an elongated groove 312 communicating with the second slots 311, and a second Z-axis limiting member 37 corresponding to the first Z-axis limiting member 16 of the first housing 11; wherein the opening height of the elongated groove 312 matches the thickness of the flat plate portion 21 of the plate-shaped terminals 20, and the first Z-axis limiting member 16 and the second Z-axis limiting member 37 maintain an X-axis gap dx and a Y-axis gap dy. In one embodiment, the second Z-axis limiting member 37 includes two recesses 371 and 372 corresponding to the two protrusions 161 and 162 of the first outer shell 11. The X-axis depth of each recess 371 and 372 is greater than the X-axis width of its corresponding protrusion 161 and 162, and the Y-axis depth of each recess 371 and 372 is greater than the Y-axis length of its corresponding protrusion 161 and 162, thus forming the X-axis gap dx. The Z-axis depth of each recess 371 and 372 matches the Z-axis height of its corresponding protrusion 161 and 162, thus forming the Y-axis gap dy. Furthermore, the two recesses 371 and 372 are respectively formed at the two corners of the front side of the second outer shell 31, that is, each recess 371 and 372 is recessed from the top surface 34, the rear side surface 33, and an outer side surface 36 of the second outer shell 31. (See also...) Figure 3A As shown, the second outer casing 31 is fitted from bottom to top into the receiving space 110 of the first outer casing 11. Furthermore, as... Figure 2 As shown, the front side 32 and bottom surface 35 of the second outer casing 31 extend forward from the recess 17 of the bottom surface 15 of the first outer casing 11 by a baffle 38, as shown. Figure 5 As shown, the baffle 38 is fitted into the recess 17 of the bottom surface 15 of the first housing 11.

[0060] The resilient terminals 40 of the aforementioned male electrical connector 30 are respectively inserted into the second slot 311, and the resilient arm 41 of each resilient terminal 40 protrudes from its corresponding second slot 311, such as... Figure 5 As shown, and contacts the flat plate portion 21 corresponding to the plate-shaped terminal 20, and as Figure 6As shown, the first width W1 of the flat plate portion 21 is not less than the second width W2 of the elastic arm 41; and the outer connecting portion 42 of the elastic terminal 40 protrudes from the rear side 33 of the second housing 31. In one embodiment, each elastic terminal 40 is a vertical tuning fork with two vertically opposing elastic arms 411 and 412, which respectively contact the upper and lower surfaces of the flat plate portion 21 of the corresponding plate terminal 20.

[0061] Please see again Figure 3B As shown, at Figure 3A After inserting the second housing 31 of the male electrical connector 30 into the receiving space 110 of the first housing 11 of the female electrical connector 10 from bottom to top, first insert the plate terminals 20 of the female electrical connector 10 into the first slots 111 respectively, such as... Figure 5 As shown, the flat plate portion 21 of each plate-shaped terminal 20 protrudes from the first slot 111 and enters the elongated groove 312 and the corresponding second slot 311; and so on. Figure 3C As shown, the elastic terminals 40 are then inserted into the corresponding second slot 311 from the rear side 33 of the second housing 31, and the two elastic arms 411 and 412 are inserted forward into the flat plate portion 21 in the first slot 111 and come into contact with it.

[0062] like Figure 1 and Figure 4 As shown, after the first housing 11 and the second housing 31 are assembled, they indeed form an X-axis gap dx and a Y-axis gap dy in the XY plane. Furthermore, each of the elastic terminals 40 inside the second housing 31 is inserted into the first slot 111 to contact the flat portion 21 of the corresponding plate-shaped terminal 20. The flat portion 21 of the plate-shaped terminal 20 is inserted into the second slot 311 and the elongated groove 312 of the second housing 31. Therefore, as... Figure 6 As shown, when the first housing 11 and the second housing 31 are combined and move back and forth along the X-axis or Y-axis, the elastic terminal 40 can maintain contact with the plate terminal 20 without disengaging; therefore, the X-axis gap dx and the Y-axis gap dy both fall within the contact (overlap) range between the elastic terminal 40 and its corresponding plate terminal 20.

[0063] like Figure 5 As shown, since the first housing 11 and the second housing 31 are combined in a single direction along the Z-axis, if there is a slight movement in the opposite direction (from top to bottom) of the Z-axis after the combination, the two elastic arms 411 and 412 of the elastic terminal 40 of the second housing 31 are located on the Z-axis, so the slight movement along the Z-axis can be absorbed. Thus, the floating electrical connector assembly of this utility model can indeed provide XYZ three-axis floating function.

[0064] In summary, the floating electrical connector assembly of this utility model mainly provides corresponding first and second Z-axis limiting members for the first and second housings, and the first and second Z-axis limiting members maintain a Y-axis gap and an X-axis gap, allowing the first and second housings to move slightly relative to each other along the XYZ axes. In addition, the flat plate portion of the plate-shaped terminal of the female electrical connector is parallel to the XY plane, and its first width is not less than the second width of the elastic arm of the elastic terminal of the male electrical connector. Therefore, when the first and second housings move slightly relative to each other along the X-axis or Y-axis, the flat plate portion of each plate-shaped terminal still maintains contact with the elastic arm of the elastic terminal. As for the first and second housings moving slightly relative to each other along the Z-axis, since the elastic arm of each elastic terminal contacts the flat plate portion corresponding to the plate-shaped terminal, the contact state is also maintained. Therefore, the floating electrical connector assembly of this utility model can indeed provide a three-axis micro-motion function.

[0065] The above description is merely an embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above by way of embodiment, it is not intended to limit the present utility model. Anyone skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the spirit and essence of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the content of the present utility model shall still fall within the scope of protection of the present utility model and the claims.
