In the prior art, an electrical connector includes an insulative housing and a plurality of terminals received in the insulative housing, each of the terminals has an extension arm extending out of an upper surface of the insulative housing, and each of the extension arms has a mating portion bent and extended. The upper surface of insulator is equipped with a plurality of lugs, and is a plurality of the lug is with a plurality of the terminal one-to-one, just the lug with the extension arm is dislocation set. Therefore, when a chip module is abutted against the butting part downwards, the lug can prevent the elastic arm from being excessively deformed under stress, so that the elastic arm is prevented from being fatigued.

However, since the protrusion and the extension arm are disposed in a staggered manner, the insulation body needs to provide sufficient space for the protrusion. As such, the distance between two adjacent terminals is increased, which is not favorable for the terminal of the electrical connector to be densely developed. And because when the terminal is inserted into the insulating body and the insulating body is abutted with a circuit board, the insulating body can be stressed to enable two sides of the insulating body to warp upwards or downwards. Therefore, the heights of the bumps are uneven, the bumps with lower heights cannot play a supporting role, the contact force between the butting parts of the terminals corresponding to the bumps with lower heights and the chip module is smaller, and the butting parts cannot be stably butted with the chip module, so that the signal transmission between the terminals and the chip module is influenced.

Therefore, there is a need to design an electrical connector to solve the above-mentioned technical problems.

[ detailed description ] embodiments

The invention will now be described in further detail with reference to specific embodiments and figures for a better understanding of the invention.

In order to facilitate understanding of the technical scheme of the invention, an X axis in three-dimensional coordinate axes in the drawings of the specification is defined as a front-back direction, a Y axis is defined as a left-right direction, and a Z axis is defined as a vertical direction.

Fig. 1 to 5 show a first embodiment of the present invention.

As shown in fig. 1, fig. 2 and fig. 5, an electrical connector B is provided, wherein an upper portion of the electrical connector B is electrically connected to a chip module a, and a lower portion of the electrical connector B is abutted to a circuit board C. The electrical connector B includes an insulative housing 1 and a plurality of terminals 2 disposed in the insulative housing 1, each terminal 2 extends upward and forward to have an extension arm 22, and the extension arm 22 is exposed upward from the insulative housing 1. Each of the extension arms 22 is bent and extended to have a docking portion 23, and the docking portion 23 is used for electrically connecting with the chip module a.

As shown in fig. 1, 2 and 3, the insulating housing 1 has an upper surface 11 and a lower surface 12, a plurality of receiving holes 13 are formed in the insulating housing 1, and the receiving holes 13 vertically penetrate through the upper surface 11 and the lower surface 12. The plurality of receiving holes 13 are arranged in a plurality of rows in the left-right direction, the plurality of terminals 2 correspond to the plurality of receiving holes 13 one by one, and each terminal 2 is received in the corresponding receiving hole 13.

As shown in fig. 2, 3, 4 and 5, the upper surface 11 of the insulating body 1 is provided with a plurality of first supporting portions 111, the plurality of first supporting portions 111 correspond to the plurality of receiving holes 13 one by one, and each first supporting portion 111 is located in front of the corresponding receiving hole 13. Each of the first supporting portions 111 has a first end portion 1111, and the first end portion 1111 is located at a top end of the first supporting portion 111 for abutting against the abutting portion 23. The first supporting portion 111 is gradually reduced from bottom to top, the first end portion 1111 is gradually reduced to a horizontal straight line, and the horizontal straight line extends in the front-rear direction. Of course, in other embodiments, the first end 1111 may be configured as an arc, a plane, or the like. However, it is necessary to ensure that the width of the first support part 111 at the first end 1111 is smaller than the width of the first support part 111 away from the abutting part 23. When the abutting portion 23 abuts against the first end portion 1111, the abutting portion 23 can more easily pierce the first end portion 1111 because the width of the first end portion 1111 is smaller. Each of the first supporting portions 111 further has a concave portion 1112, and the concave portion 1112 is formed by the abutting portion 23 abutting against and penetrating into the first supporting portion 111. The concave portion 1112 stops the abutting portion 23 from moving along the extending direction of the extension arm 22, so as to prevent the extension arm 22 from being pressed and excessively deformed, and prevent the extension arm 22 from fatigue.

As shown in fig. 1, fig. 2 and fig. 4, the lower surface 12 of the insulating body 1 is provided with a plurality of first abutting blocks 121 and a plurality of bumps 122, and the number of the bumps 122 is equal to the number of the first abutting blocks 121. The first abutting blocks 121 correspond to the receiving holes 13 one by one, and the bumps 122 correspond to the receiving holes 13 one by one. The first abutting block 121 is located in front of the corresponding bump 122, and the first abutting block 121 is used for abutting against the terminal 2. The bump 122 abuts against the surface of the circuit board C to prevent the terminal 2 from being pressed and excessively deformed and displaced. The plurality of first abutting blocks 121 and the plurality of first supporting portions 111 are symmetrically arranged in the vertical direction, and the first abutting blocks 121 are arranged in a tapered manner from top to bottom. The first abutting block 121 has a first abutting portion 1211, and the first abutting portion 1211 is configured to abut against the terminal 2. The first abutting portion 1211 tapers into a horizontal straight line extending in the front-rear direction. Of course, in other embodiments, the first abutment 1211 can be configured as an arc, a plane, or the like. However, it is necessary to ensure that the width of the first abutting block 121 at the first abutting portion 1211 is smaller than the width of the first abutting block 121 away from the circuit board C. When the terminal 2 abuts against the first abutting portion 1211, the terminal 2 can easily pierce the first abutting block 121 because the width of the first abutting portion 1211 is small. The first abutting block 121 further has a first groove 1212, the first groove 1212 is formed by the terminal 2 penetrating into the first abutting block 121, and the first groove 1212 is used for limiting the terminal 2 and preventing the terminal 2 from moving in the front-rear direction.

As shown in fig. 1, 3 and 4, each of the terminals 2 has a base portion 21, and the base portion 21 is received in the receiving hole 13. The extension arm 22 is bent upward from the upper end of the base 21 and extends, and the extension arm 22 is exposed on the upper surface 11 of the insulating body 1. The thickness of the extension arm 22 in the up-down direction is greater than the support width of the first end 1111 of the first support part 111. The extension arm 22 bends and extends to form the abutting portion 23, and the plurality of abutting portions 23 correspond to the plurality of first supporting portions 111 one by one. The abutting portion 23 is provided with an abutting surface 231, the abutting surface 231 is an arc surface (in other embodiments, the abutting surface 231 may also be a horizontal surface, or a straight line, a pair of contacts, etc.), and the abutting surface 231 is used for abutting with the chip module a. Each of the abutting portions 23 further has a free end portion 232 and a supporting portion 233 located behind the free end portion 232. The abutting portion 233 is located below the abutting surface 231, and the abutting portion 233 is higher than the free end portion 232. The free end 232 has a cut surface 2321, and the cut surface 2321 is a rectangular inclined surface (in other embodiments, the cut surface 2321 may also have other shapes such as an arc surface, etc.). The cutting surface 2321 is symmetrically provided with a first side 23211 and a second side 23212, and a third side 23213 and a fourth side 23214 which are respectively connected to the first side 23211 and the second side 23212, wherein the length of the first side 23211 is equal to the length of the second side 23212. The third side 23213 and the fourth side 23214 are symmetrically disposed, and the length of the third side 23213 is equal to the length of the fourth side 23214. The length of the first side 23211 is greater than the length of the third side 23213, and the length of the third side 23213 is equal to the thickness of the extension arm 22. The second side 23212 is located above the first side 23211, and when the chip module a abuts against the abutting surface 231 downwards, the first side 23211 abuts against the first end 1111 and is accommodated in the recess 1112.

As shown in fig. 1, fig. 3 and fig. 4, the lower end of the base 21 extends to form a supporting arm 24, and the supporting arm 24 is exposed from the lower surface 12 of the insulating body 1. The support arm 24 is bent and extended to have a bending portion 25, and the bending portion 25 is used for contacting with the circuit board C. Each of the bending portions 25 further has a first pressing portion 251 and a second pressing portion 252 located behind the first pressing portion 251, and the second pressing portion 252 is lower than the first pressing portion 251. The first pressing portion 251 abuts against the first abutting portion 1211 and pierces into the first abutting block 121 to form a first groove 1212. Two connecting portions 26 are bent and extended from the left and right sides of each base portion 21, and the upper ends of the connecting portions 26 are flush with the upper surface 11 of the insulating body 1 for connecting with a tape (not shown, the same below).

As shown in fig. 1, 2, 4 and 5, when the electrical connector B abuts against the circuit board C, the chip module a is not in contact with the electrical connector B. The base 21 is correspondingly accommodated in the accommodating groove, the bending portion 25 abuts against the circuit board C, and the first pressing portion 251 penetrates into the first abutting block 121 to form the first groove 1212. Because the terminal 2 is inserted into the insulating body 1 and the circuit board C is abutted against the electric connector B, a force is applied to the insulating body 1. Both sides of the insulative body 1 are warped upward, resulting in that the first end 1111 of the first support part 111, which is closer to the center of the insulative body 1, among the plurality of first support parts 111 is lower than the first end 1111 of the first support part 111, which is farther from the center of the insulative body 1. In other embodiments, the terminal 2 is inserted into the housing 1, and the circuit board C is pressed against the electrical connector B, so that a force is applied to the housing 1. Both sides of the insulative body 1 are warped downward, resulting in a height of the first end 1111 of the first support part 111 closer to the center of the insulative body 1 among the plurality of first support parts 111 being higher than a height of the first end 1111 of the first support part 111 farther from the center of the insulative body 1. The abutting portion 23 is located above the first supporting portion 111, and a projection of the abutting portion 23 overlaps a projection of the first supporting portion 111 in the vertical direction.

As shown in fig. 1, 3, 4 and 5, when the chip module a abuts against the abutting portion 23, the abutting surface 231 contacts with the chip module a. The extension arm 22 moves downward and forward, and the first side 23211 abuts against the first end 1111 and pierces into the first supporting portion 111 to form the recess 1112. Since both sides of the insulating body 1 are warped upward, when the first side 23211 pierces the first supporting portion 111, a recess depth of the recess 1112 close to the center of the insulating body 1 among the plurality of recesses 1112 is smaller than a recess depth of the recess 1112 far from the center of the insulating body 1. Of course, in other embodiments, since both sides of the insulating body 1 are warped downward, when the first side 23211 penetrates into the first supporting portion 111, the recessed depth of the recessed portion 1112 close to the center of the insulating body 1 is greater than the recessed depth of the recessed portion 1112 far from the center of the insulating body 1 in the plurality of recessed portions 1112.

As shown in fig. 6, 7, 9, 10 and 11, a second embodiment of the electrical connector B is different from the electrical connector B of the first embodiment in that the remaining structure and connection relationship are the same as those of the first embodiment: the upper surface 11 of the insulating body 1 is provided with a plurality of supporting blocks 112, the supporting blocks 112 correspond to the accommodating holes 13 one by one, and each supporting block 112 is located in front of the corresponding accommodating hole 13. The top surface of each supporting block 112 is provided with a first supporting portion 111 and a second supporting portion 113. The second supporting portion 113 is located behind the first supporting portion 111, and a front end of the second supporting portion 113 is connected to a rear end of the first supporting portion 111 (of course, in other embodiments, the upper surface 11 of the insulating body 1 directly extends upwards to form a plurality of first supporting portions 111 and a plurality of second supporting portions 113, and a front end of the second supporting portion 113 is not connected to a rear end of the first supporting portion 111). The second supporting portion 113 is elongated, and a second end 1131 is disposed at a top end of the second supporting portion 113. The height of the second end portion 1131 is higher than that of the first end portion 1111 along the vertical direction, and the second end portion 1131 is used for abutting against the abutting portion 233. The second supporting portion 113 is tapered from bottom to top, and the second end portion 1131 is tapered to a horizontal straight line extending in the left-right direction. Of course, in other embodiments, the second end 1131 may be configured as an arc, a flat surface, or the like. However, it is necessary to ensure that the width of the second support portion 113 at the second end 1131 is smaller than the width of the second support portion 113 away from the abutting portion 23. Thus, when the supporting portion 233 supports against the second end portion 1131, the supporting portion 233 can more easily pierce the second end portion 1131 because the width of the second end portion 1131 is smaller. Each of the second supporting portions 113 further has a limiting portion 1132, and the limiting portion 1132 is abutted by the abutting portion 233 and penetrates into the second supporting portion 113. The stopper 1132 stops the extension arm 22 from moving in a left-right direction perpendicular to an extending direction of the extension arm 22.

As shown in fig. 6, 7, 9 and 10, a plurality of second abutting blocks 123 extend downward from the lower surface 12 of the insulating main body 1, the plurality of second abutting blocks 123 correspond to the plurality of receiving holes 13 one by one, and the second abutting blocks 123 are located in front of the corresponding receiving holes 13. The second abutting block 123 is located behind the first abutting block 121, and a front end of the second abutting block 123 is connected to a rear end of the first abutting block 121 (of course, in other embodiments, a plurality of protrusions are also provided on the lower surface 12 of the insulating body 1, the plurality of protrusions correspond to the plurality of receiving holes 13 one by one, each protrusion is located in front of the corresponding receiving hole 13, a bottom surface of each protrusion is provided with one first abutting block 121 and one second abutting block 123, and a front end of the second abutting block 123 is not connected to a rear end of the first abutting block 121). The second abutting block 123 is in a longitudinal shape, and a second abutting portion 1231 is disposed at the bottom end of the second abutting block 123. The height of the second abutting portion 1231 is lower than the height of the first abutting portion 1211 along the vertical direction, and the second abutting portion 1231 is configured to abut against the bending portion 25. The second abutting portion 123 is tapered from top to bottom, and the second abutting portion 1231 is tapered into a horizontal straight line extending in the left-right direction. Of course, in other embodiments, the second abutting portion 1231 may be configured as an arc, a plane, or the like. However, it is necessary to ensure that the width of the second abutting block 123 at the second abutting portion 1231 is smaller than the width of the second abutting block 123 away from the bending portion 25. The second abutting block further has a second groove 1232, the second groove 1232 is formed by the bending portion 25 penetrating into the second abutting block 123, and the second groove 1232 is used for limiting the abutting arm 24 and preventing the abutting arm 24 from moving in the left-right direction.

As shown in fig. 7, 9, 10 and 11, when the electrical connector B abuts against the circuit board C, the chip module a is not in contact with the circuit board C. Because the terminal 2 is inserted into the insulating body 1 and the circuit board C abuts against the electrical connector B, a force is applied to the insulating body 1. Therefore, the two sides of the insulating body 1 are warped upwards, so that the height of the second end 1131 of the second supporting portion 113 close to the center of the insulating body 1 among the plurality of second supporting portions 113 is lower than the height of the second end 1131 of the second supporting portion 113 far from the center of the insulating body 1. Of course, in other embodiments, since the terminal 2 is inserted into the insulating body 1 and the circuit board C abuts against the electrical connector B to exert a force on the insulating body 1, both sides of the insulating body 1 are warped downward, so that the second end 1131 of the second supporting portion 113 near the center of the insulating body 1 in the plurality of second supporting portions 113 is higher than the second end 1131 of the second supporting portion 113 far from the center of the insulating body 1. As shown in fig. 8, 9 and 10, when the chip module a abuts against the abutting portion 23, the abutting surface 231 contacts the chip module a. The extension arm 22 moves downward and forward, and the abutting portion 233 abuts against the second end portion 1131 and penetrates into the second supporting portion 113 to form the limiting portion 1132. Because the two sides of the insulator 1 are warped upwards, when the supporting portion 233 pierces the second supporting portion to form the position-limiting portion 1132, the depth of the recess of the position-limiting portion 1132, which is close to the center of the insulator 1, of the position-limiting portions 1132 is smaller than the depth of the recess of the position-limiting portion 1132, which is far from the center of the insulator 1. Of course, in other embodiments, because two sides of the insulating body 1 are warped downward, when the abutting portion 233 penetrates into the second supporting portion 113 to form the limiting portion 1132, a depth of the recess of the limiting portion 1132, which is close to the center of the insulating body 1, of the limiting portions 1132 is greater than a depth of the recess of the limiting portion 1132, which is far from the center of the insulating body 1.

To sum up, the utility model discloses electric connector B has following beneficial effect:

(1) the utility model provides a plurality of free end 232 is with a plurality of first supporting part 111 one-to-one, it is a plurality of support portion 233 with a plurality of second supporting part 113 one-to-one, work as chip module A butt during butt joint portion 23, free end 232 butt in first supporting part 111, and pierce form in first supporting part 111 depressed part 1112, depressed part 1112 stops butt joint portion 23 is followed the extending direction displacement of extension arm 22, support portion 233 support in second supporting part 113. Because the free end 232 abuts against the first supporting portion 111 and the abutting portion 233 abuts against the second supporting portion 113, when the chip module a abuts against the abutting portion 23, both the first supporting portion 111 and the second supporting portion 113 can support the abutting portion 23, so that the supporting force for supporting the abutting portion 23 is enhanced, and the abutting portion 23 is prevented from being stressed and deformed. Moreover, since the plurality of free end portions 232 correspond to the plurality of first supporting portions 111 one to one, the plurality of abutting portions 233 correspond to the plurality of second supporting portions 113 one to one, and the first supporting portions 111 and the second supporting portions 113 are both located right below the abutting portion 23, the insulating body 1 does not need to reserve an extra space for the first supporting portions 111 and the second supporting portions 113, so that the distance between two adjacent terminals 2 is reduced, and the terminals 2 of the electrical connector B are favorably developed in an intensive manner. When the chip module a abuts against the abutting portion 23, the free end portion 232 of the abutting portion 23 abuts against the first supporting portion 111 and pierces into the first supporting portion 111 to form the recess 1112. The recessed portion 1112 can stop the deformation displacement of the abutting portion 23 in the extending direction of the extension arm 22, so as to prevent the extension arm 22 from being excessively deformed by a force, and prevent the extension arm 22 from generating fatigue. Moreover, the two sides of the insulating body 1 are stressed to warp upwards or downwards, so that the heights of the first supporting parts 111 are uneven. However, since the recess 1112 can move the abutting portion 23 downward within a certain range, the abutting portions 23 can be abutted against the corresponding first supporting portions 111, so that the abutting portions 23 can be stably abutted against the chip module a, and the signal transmission between the terminal 2 and the chip module a is more stable.

(2) The first side 23211 pierces the first supporting portion 111, and the length of the first side 23211 is greater than the thickness of the extension arm 22. When the force applied by the chip module a to the docking portion 23 is a constant magnitude, since the first side 23211 and the first end 1111 are both straight lines, the contact area between the first supporting portion 111 and the docking portion 23 is small, the first side 23211 is easier to pierce into the first supporting portion 111, and the length of the first side 23211 is greater than the thickness of the extension arm 22, so that, since the extension arm 22 is slightly shifted in the left-right direction during the pressing movement of the extension arm 22, the length of the first side 23211 is long, and even if the extension arm 22 is slightly shifted in the left-right direction, the first side 23211 can accurately abut against the first end 1111 of the first supporting portion 111.

(3) When the free end of the abutting portion 23 penetrates into the recess 1112, the recess 1112 near the center of the insulating body 1 among the plurality of recesses 1112 has a recess depth larger or smaller than the recess 1112 far from the center of the insulating body 1. In this way, the recessed portion 1112 can allow the extension arm 22 to move downward within a certain range, which can ensure that a plurality of the butting portions 23 can stably abut against the chip module a, so that the signal transmission between the terminal 2 and the chip module a is more stable.

(4) When the chip module a abuts against the abutting portion 23, the abutting portion 233 abuts against the second supporting portion 113 and pierces into the second supporting portion 113 to form the limiting portion 1132, and the limiting portion 1132 stops the abutting portion 23 from displacing along the extending direction perpendicular to the extending arm 22. Thus, the limiting portion 1132 may limit the docking portion 23 in the left-right direction, so as to prevent the extension arm 22 from moving left and right due to external impact, so that the signal transmission between the terminal 2 and the chip module a is more stable.

The above detailed description is only for the purpose of illustrating the preferred embodiments of the present invention, and not for the purpose of limiting the scope of the present invention, therefore, all the equivalent technical changes using the description and drawings of the present invention are included in the scope of the present invention.
