Description of the Invention: [Technical Field 1 of the Invention] The present invention relates to an electrical connector. Specifically, the present invention relates to an electrical connector and an electrical connector system for connecting circuit boards together. [Prior Art] An electrical connector system in which boards are directly connected has been used to connect circuit boards, and electrical components are mounted on the boards. Forming the connector system such that a socket connector is fixed to one of the circuit boards, a corresponding plug connector is fixed to the other circuit board, and the circuit boards are connected by the plug connector Plug into the socket connector and connect them together. With this configuration, the electrical connections of the boards are simplified and the cost is reduced by the absence of wires. In the automotive field, electronic boards have many uses due to the variety of control circuits and the variety of functional choices (such as multimedia systems). Along with this, there are many opportunities to use the connectors to connect these boards together. There are many cases where there is less work space when assembling a car. 1 The operation needs to be greatly simplified. Therefore, it is desirable to have a system that connects boards directly together. Circuit boards used in automobiles typically suffer from vibrations that cause the natural frequencies of the boards to differ, and several connected boards rarely vibrate in different modes of vibration. Since the electrical contacts of the connectors connected to the boards are moved relative to each other in different modes (4), and this results in electrical contact. One of the phenomena of the increase in the resistance of the knife (frictional corrosion, therefore, it is necessary to fix the 荨 circuit board to a rigid support frame by fixing the 153057.doc 201145707 connected circuit board. The invention provides a contact terminal for an electrical connector, each terminal comprising: a first electrode 'which is connected to the electrode of the plug connector; and a a second electrode connected to the ρ-plane circuit board. The first electrode (four) is connected to the second electrode by a resilient, variable material, flexible connecting portion, and the flexible connecting portion has the first electrode The electrode and (four) two electric (four) defined - in-plane - or a plurality of straight portions or curved portions. The flexible connecting portion may have a wave shape. The present invention further provides a socket connector, the terminals are disposed in In the socket connector, the socket connector has: a fixed socket housing having a second electrode connected to the circuit board; and a floating housing having the electrode connected to the plug connector First electricity Due to the elastic deformation of the flexible connecting portion of the terminals, the fixed housing and the floating housing are coupled to be relatively movable. The fixed housing and/or the floating housing of the receptacle connector The stopper provided in the body prevents relative movement between the fixed socket housing and the floating socket housing in a direction orthogonal to the insertion direction of the plug connector. One of the flexible connecting portions The channel portion is formed in the floating housing of the socket in a direction parallel to the insertion direction of the plug, and the flexible connecting portion is elastically deformable in the channel portion along the insertion direction of the plug. The channel portion prevents the terminal from being positively The fixed housing of the socket connector has a fixed protrusion protruding along the direction of the insertion direction of the 153057.doc 201145707. #犬月. The socket connection benefits The floating housing has a floating limiting block protruding toward the solid protruding piece in a direction orthogonal to the insertion direction ‧^<1:. _^111_<^,,1. 4 floating housing can Along the plug connector between the position at which the floating restricting block contacts the floating (four) stop provided by the fixing tab and the position at which the floating housing contacts the relatively housing of the receptacle connector Moving in the direction of insertion, having a notch portion forming a concave π in a surface parallel to the insertion direction - is formed in the socket connector "the plug connector is corresponding to the locking blade a locking spring is disposed at a position. Due to a partial contact with the socket connector, a protruding portion is engaged with the locking portion to be formed on the locking spring t, and is moved away by moving toward the insertion direction of the plug One direction of the notch portion elastically deforms the lock spring. The receptacle connector may have one rotation preventing spring protruding in one direction orthogonal to the insertion direction. The plug connector may have a rotation preventing tab at a position corresponding to one of the rotation preventing springs, the rotation preventing tab having a surface facing a direction orthogonal to a protruding direction of the rotation preventing spring. When the S-Hui plug connector is inserted into the receptacle connector, the rotation preventing spring prevents the plug connector from rotating. The invention further provides a connector system comprising any of the receptacle connectors described above; and a plug connector mated with the receptacle connector. The plug connector has a fixed plug housing and a floating plug housing. The floating plug housing is connected to the socket connector and is capable of being in a predetermined floating range along one of 153057.doc -6 - 201145707 insertion directions orthogonal to the plug connector, a relative movement, but not in Move in the insertion direction. In this connector system, when the plug connector and the receptacle connector are mated, the floating plug body and the floating socket housing can be integrally assembled to form a combined floating housing. The fixed socket housing and the combined floating body can move relative to each other in the insertion direction within a prescribed floating range, and the i_eight, etc. 3b are orthogonal to the insertion direction in the range of exceeding the prescribed tolerance floating range Move relative to each other. The fixed plug housing and the 'joint floating double body can move relative to each other in a direction orthogonal to the insertion direction within a prescribed floating range', but the same cannot move relative to each other in the insertion direction within a predetermined tolerance range . The fixed housing and the floating housing of the socket. A stop provided in each of the solid housing and the floating housing of the plug is limited to the specified floating range.

The plug connector 40 includes a fixed plug housing 41, a floating plug housing 42, and a terminal 43. The fixed plug housing 41 and the floating plug housing 42 are formed by resin molding, and the terminal 43 is formed of a conductive material such as a copper alloy. 153057.doc 201145707 As shown in Fig. 1, the direction of the longitudinal axis of the socket connection si (i.e., the direction of the arrangement terminal) is defined as the X direction. The plug connector 40 is inserted into the receptacle connector 1 and the direction of retraction from the receptacle connector i is defined as the z-direction. The height direction of the socket connection 1 (i.e., the direction orthogonal to the X direction and the Z direction) is defined as the γ direction. The x direction, the Y direction, and the Z direction are orthogonal to each other. FIG. 7A and FIG. 78 show the terminal 4 of the receptacle connector 1 and the 4% terminals 4, 4: each includes: a first electrode 6, a second The electrode 7 and a flexible connecting portion are connected to the first electrode 6 and the second electrode 7. When the first electrode 6 is coupled to the plug connector 4 (refer to FIG. 3 and FIG. 3B), the plug connector m is connected by contacting the first electrode material of one of the terminals 43 of the plug connector 4A. An electrical connection is formed between the devices 4G. The flexible connecting portion 8 electrically and mechanically connects the first electrode 6 and the second electrode 7, and since the flexible connecting portion 8 is electrically conductive and elastically deformed, between the first electrode 6 and the second electrode 7 There may be relative displacement. In this embodiment t, the first electrode is bent to approximately 90 by a press working or the like and then by a thickness direction of one of the conductive metal sheets along a prescribed thickness. When the metal piece is punched at an angle, the terminals 4, 41 are formed. The flexible connecting portion 8 is punched in a wave shape, thereby being elastically changed in the thickness direction and the surface direction of the metal piece (ie, 'in the χ direction, the γ direction, and the z direction) when being viewed from the Y direction, and fixed The socket housing 2 is approximately c-shaped and is fixed to the bottom circuit board (a plurality of support channels not shown in the branch (four) two electrodes 7 are formed in the fixed socket housing 2 153057.doc 201145707 direction self-insertion The surface P1 is disposed at the distal end of the channel 10. Both ends of the fixed socket housing 2 in the X direction (only one of which is shown in Figs. 4A and 4B) have a shoulder portion 12 projecting toward the insertion surface pi in the Z direction. When the shoulder portion 12 is inserted into the fixing tab 14, a fixing tab 14 is formed in an approximately C-shaped cross section to cover the outer periphery of the shoulder portion 12. The fixing tab is formed of a material such as a metal piece. 14. One of the fixing tabs 14 constitutes a floating stop 13' in cooperation with one of the floating socket housings 3 (hereinafter to be described), and a floating socket facing the plug connector 40 in the z direction The displacement of the housing 3. Figure 4A and Figure 4B show the float The movable stopper 13 and the floating restricting block 22 are not in contact with each other but separated by the space 21 in the z direction. As shown in Fig. 2A, the floating socket housing 3 has a cavity or opening for receiving the plug connector 40. The portion 16' and the floating housing 3 are connected to the fixed socket housing 2 via the terminals 4, 4· to extend the opposite wall of the floating socket housing 3 in the X direction, such that the foot portion 18 (Fig. 4A and 4B) protruding toward the bottom surface. The plurality of support channels 21 receiving the first electrode 6 are formed in parallel with the X direction between the inner surfaces of the opposite walls forming the opening portion 16 in the Y direction. The flexibility of arranging the terminal 4 is formed. The mounting passage 20 of the connecting portion 8 has a width equal to or slightly larger than one of the thicknesses of the flexible connecting portion 8 to allow deformation of the flexible connecting portion 8 in the Z direction while restricting the X direction and the Y direction.

As shown in Figures 4A and 4B It is shown that a floating restricting block 22 protrudes outward from each side of the floating socket housing 3 in the X direction. A space z1 is set between the floating stopper and the floating restricting block 22. Therefore, the floating socket housing 3 becomes It can be moved relative to the fixed socket body 2 until the floating limiting block 22 is brought into contact with the floating stopper 13. On the other hand, when the leg portion "contacts the fixed socket housing 2, the restriction is restricted away from the plug in the z direction.

Considering the dimensional tolerance of the fixed socket housing 2 and the floating socket housing 3, a predetermined gap x1 can be set between the floating socket housing 3 and the shoulder portion 2 in the X direction. The gap x1 ensures that the fixed socket housing 2 and the floating socket housing 3 are assembled together while limiting the relative displacement of the fixed socket housing 2 and the floating socket housing 3 to the amount of the gap X1 in the X direction. At this point, it is considered that the fixed socket housing 2 and the floating socket housing 3 cannot move relative to each other in the X direction. Similarly, in order to assemble the fixed socket housing 2 and the floating socket housing 3 together, a gap yl ' is set between the floating limiting block 22 and the shoulder portion 12 in the Y direction, whereby the floating socket housing 3 can only be opposed to The fixed socket housing 2 is displaced in the γ direction by the amount of the gap yl close to the circuit board (referred to as the first orthogonal direction 33a in the context). Further, a gauge gap y2 is set between the floating restricting block 22 and the fixed tab 14 in the Y direction. The floating socket housing 3 can only be displaced away from the circuit board (referred to as the second orthogonal direction 33b in the context) in the Y direction relative to the fixed socket housing 2 by the amount of gap y1, y丨 and "" The amount of floating displacement in the Z direction is approximately 10 to 20 times. 153057.doc • 10· 201145707 The connector system according to an embodiment of the present invention may include a __ rotation preventing mechanism, and the part of the rotation preventing mechanism is formed On the inner surface of the opposite wall of the floating socket housing 3 in the Y direction (refer to FIG. 5), a rotation preventing guide passage 24, a rotation preventing bobbin 26 and a support are provided and the rotation preventing spring 26 is inserted therein.

A locking mechanism is provided at a position on the plug connector 4 of the locking mechanism corresponding to the receptacle connector 1 for locking the plug connector 40 and the receptacle connector by movement of the locking mechanism coupled to the socket connection Si i. Referring to Figures 3A and 3B, the locking mechanism has a locking spring 52 extending in the Z direction on the outer surface of the floating plug housing 42. A projecting portion 54 is provided at a position on the lock spring 52 of the fixed plug housing 41 away from the insertion surface P2 by a predetermined distance in the 2 direction. When the receptacle connector i is fully coupled to the plug connector 40, the protruding portion 54 of the lock spring 52 enters the aperture 32 of the locking blade 30. The floating socket housing 3 and the floating plug housing 42 are locked, thereby preventing relative displacement between the electrode 5 and the electrode 44. Figure 8 shows a diagram of a terminal 43 for a plug connector 4A. The terminal "haves a first electrode 44, a second electrode 45 and a flexible connecting portion 46. When the first electrode 44 is coupled to the corresponding electrode 6 of the receptacle connector i, by contacting the terminal 4 of the receptacle connector 1 The first electrode 6 establishes an electrical connection between the receptacle connector and the plug connector 40. The second electrode 45 is mounted or soldered to the circuit board between the plug connector 4 and the circuit board. An electrical connection is formed. The flexible connection portion 46 electrically and mechanically connects the first electrode 44 and the second electrode 45. There may be a relative displacement between the first electrode 44 and the second electrode 45 because the flexible connection portion 46 153057.doc •12- 201145707 In this embodiment, a conductive metal of a prescribed thickness is formed by punching by press working or the like or by bending or the like by press working or the like. At the time of sheeting, the terminal 43 is formed. The flexible connecting portion 46 is pressed in a wave shape, thereby being elastically deformed in the thickness direction and the surface direction (i.e., the χ direction, the Y direction, and the Z direction) of the metal piece. Direction inspection, solid One of the plug housing 41 having an approximately rectangular-based cross-sectional shape, and may be mounted to a circuit board (not shown). A plurality of channels 56 support system for supporting the second electrode 45 is formed on the fixing of the plug housing. " The support passage 56 is disposed in the parallel X direction on the two opposite walls forming the fixed plug housing 41 in the γ direction (Fig. 3A). A shoulder portion 58 (Fig. 6) is formed on both sides of the fixed plug housing 41 in the X direction. A retaining tab 6 is formed as an approximately c-shaped cross section to cover the outer periphery of the shoulder portion 58 by inserting the shoulder portion 58 into the central space of the retaining tab 60. The fixing tab 60 is formed of a material such as a metal piece. The fixing tab 60 limits the amount of displacement of the floating plug housing 42 in the X direction and the γ direction due to the structure of the fixing tab 6 下文 which will be described later. As shown in FIG. 1, FIG. 3, and FIG. 3B, the floating plug housing 42 is formed in a shape having a hollow box facing one of the opening portions of the fixed plug housing 41, and has a complementary plug shape for inserting the socket connection. The opening portion 16 of the device. One of the ones that protrude outward in the X direction is approximately [one of the cross-sections. The floating restriction block 62 is formed in the wall of the floating plug housing 42 at both ends in the X direction. A plurality of placement walls 64 are provided inside the hollow box, and a placement passage 66 is formed between each adjacent placement wall separated by a predetermined gap. I53057 is formed on the opposite wall of the floating plug housing 42 in the Y direction. .doc • 13- 201145707 One of the seating passages 66 is formed to support one of the first electrode private support passages 68. The first electrode 44 is fixed to the inside of the support passage 68 of the floating plug housing 42. The second electrode 45 is fixed inside the support passage 56 of the fixed housing 41. Therefore, the terminal 43 connects the floating plug housing 42 and the fixed plug housing 41. The flexible connecting portion 端子 of the terminal 43 is disposed inside the seating passage 66, and is elastically deformable in the χ direction, the γ direction, and the z direction in the space in which the passage 66 is disposed. Therefore, the floating plug housing 42 is displaceable in the χ direction, the Y direction, and the Z direction with respect to the fixed plug housing 41. A space is defined between the floating restricting block 62 provided by the floating plug housing 42 in the Y direction and the shoulder portion 58 provided in the fixed housing 41. Therefore, the floating plug housing 42 can be displaced in the Y direction until the position where the floating restricting block 62 is in contact with the shoulder portion 58. Further, between the two opposing walls forming the floating plug housing 42 in the χ direction = the fixing tabs 6 provided at the ends of the fixed plug housing 41 in the X direction, therefore, The direction displaces the floating plug housing 42 until points where the two opposing walls in the χ direction contact the solid 60. A portion of the floating restricting block 62 is disposed between the fixed tab 60 and the circuit board. A gap ζ3 is set between the floating restricting block 62 and the fixing tab 6〇 and between the floating housing 42 and the circuit board. Therefore, the floating plug housing can be displaced from the position where the floating body 42 is in contact with the circuit board in the 2 directions until the floating restricting block 62 comes into contact with the fixing tab 60. The gap Ζ3 along the direction B is smaller than the displacement along the χ direction and the γ direction by approximately 1〇 to 2〇 153057.doc 14 201145707 times. Figure 9A is a cross-sectional view of one of the connector systems of the present invention before the receptacle connector 1 and plug connector 40 are coupled to each other. The circuit board R to which the receptacle connector 1 is attached extends in the X-Z plane, and the circuit board P to which the plug connector 4 is attached extends in the X-Y plane. Therefore, the board scale and the board are orthogonal to each other. In the state shown in Figs. 9A and 9B, the plug connector 40 is inserted into the receptacle connector in the z direction! In the opening portion 16. When the insertion is started, the rotation preventing projection portion 48 is first inserted into the rotation preventing guide passage 24, and then the first electrode 44 of the terminal 43 and the first electrode 6 of the terminal 4 are brought into contact with each other. When a force is applied to the plug connector of the receptacle connector i in the Z direction, the first electrode 44 of the terminal 43 is elastically deformed within the second (four) plug connector buckle and slides on the first electrode 6. When inserting the plug connector into the opening. When the p-cutter 16 has a predetermined distance, the rotation preventing projection portion is brought into contact with the protruding portion of the rotation preventing spring 26 (refer to Fig. 9b). When the plug connector 4 is inserted in the Z direction, the friction is generated due to the contact point between the rotation preventing tab 5〇 and the rotation preventing spring 26 and the contact point between the first electrode (four) first electrode 6. Force, so the flexible connecting portion 46 of the terminal 43 can be elastically deformed in the Z direction, whereby the floating plug housing (4) is pressed against the circuit board, and the flexible connecting portion 8 can be deformed in two directions, and the floating socket shell The legs of the body 3 are abutted against the fixed socket housing 2. The plug connector 40 is inserted into the plug-in connection gsl by the force of the half-, "plus" force in the Z direction.

When the plug connector 40 is slid toward the socket connector i in the Z direction, the protruding portion 54 of the locking magazine 52 is brought into contact with the edge of the inner surface of the opposite wall forming the opening portion of the socket connector in the X direction. . When the plug 40 is further slid from the position toward the inside of the opening portion 16, the locking spring 52 is elastically deformed toward the inside of the plug connector 4 in the X-Z plane, and is protruded. The P blade 54 is in contact with the locking blade 3〇. The plug connector buckle slides in this state, thereby causing the protruding portion 54 to slide on the locking blade 3〇. A projection is placed at a position corresponding to the hole 32 formed in the locking blade 30. When the p-knife 5 4 causes a force to act to restore the elastically deformed locking spring 52 to return it to its original shape, the projection 54 is placed in the hole 32. Therefore, the floating socket housing 3 and the floating plug housing are "locked together", thus establishing a stable electrical connection between the first electrode 6 of the socket connector 1 and the first electrode 44 of the plug connector 4 (refer to Fig. 9C), by making the locking force between the protruding portion 54 and the hole 32 and the frictional force on the first electrode larger than the force acting in the Z direction, the relative displacement of the electric contact can be prevented. The locking force between the portion 54 and the hole 32 and the frictional force on the first electrode are greater than the force acting in the X direction, and the relative displacement of the electrical contact can be prevented. After the coupling socket connector 1 and the plug connector 4 are closed, The circuit board r and the circuit board P can be displaced relative to each other via the flexible connecting portions 8, 46 of the floating housings 3, 42 and the respective terminals. In this embodiment, the socket connector 1 can be placed along the z side. The flexible connecting portion 8 of the terminal 4 is displaced and can be along the X direction 153057.doc

In contrast, relative to the coupling floating housing, due to the lock (four) configuration, no relative displacement occurs between the jack housing housing 3 and the floating socket housing 42. Therefore, no relative displacement occurs between the first electrode 6 of the terminal 4 and the first electrode 44 of the terminal 43. At this point, frictional corrosion is prevented. When the circuit board P is displaced in the Y direction, the floating plug housing 42 that rotates in the γ_ζ plane within the gap between the floating plug housing 42 and the opening portion 16 is applied via the terminal 43 along with the circuit board. Displacement _ force. Due to this rotation, a force causing sliding in the opposite direction of the B direction is generated on the two opposite walls forming the floating plug housing 42 in the Υ direction and on the wall of the opening portion 16. However, by setting the spring force of the rotation preventing spring 26 having an appropriate strength as a result of the frictional resistance between the rotation preventing spring 26 and the rotation preventing tab, the sliding can be prevented. Therefore, it is possible to prevent relative displacement between the electrical contacts.
