Of course, in other embodiments, the fastening portion 7 may have a smaller distance from the bottom surface 8b of the circuit board 300, and the object of the present invention can also be achieved.

As shown in fig. 7, after the assembly of the combination device is completed, in the transverse direction Y, the fourth abutting point P4 of the body portion 41 is located between the second abutting point P2 of the extending portion 5 and the first abutting point P1 of the buckling portion 7, so that when the fourth abutting point P4 abuts against the limiting portion 1341, the second abutting point P2 abuts against the top surface 8a, and the first abutting point P1 abuts against the bottom surface 8b, the fourth abutting point P4, the second abutting point P2, and the first abutting point P1 can provide a stable supporting force to the buckling piece 200 at the triangle of the buckling piece 200, thereby ensuring that the buckling piece 200 is stably located between the electrical connector 100 and the circuit board 300.
As shown in fig. 7, in the assembling process of the combination device, in the transverse direction Y, the first abutting point P1 of the latch 7 is always located between the second abutting point P2 of the extension portion 5 and the third abutting point P3 of the protrusion 42, so that when the third abutting point P3 abuts against the stop portion 1351, the second abutting point P2 abuts against the top surface 8a, and the first abutting point P1 abuts against the bottom surface 8b, the third abutting point P3, the second abutting point P2, and the first abutting point P1 can provide a stable supporting force to the latch 200 at the triangle of the latch 200, thereby ensuring that the latch 200 is stably located between the electrical connector 100 and the circuit board 300.
As shown in fig. 8, the combination of the second embodiment of the combination of the present invention differs from the combination of the first embodiment of the combination of the present invention in that: the fastening part 7 is obliquely and downwardly extended from the connecting pin 6, an included angle between the connecting pin 6 and the fastening part 7 is an obtuse angle, the fastening part 7 is provided with a plurality of protrusions 72 along an extending direction of the fastening part 7, and a joint 8d between the bottom surface 8b and the through hole 8c of the circuit board 300 and one of the protrusions 72 are mutually fastened, so that when the circuit board 300 is subjected to a downward acting force, one of the protrusions 72 inevitably gives an upward blocking force to the circuit board 300 to prevent the circuit board 300 from moving downward, that is, to block the fastening part 7 from moving upward. In this embodiment, the protrusion 72 is a circular arc protrusion. In other embodiments, the protrusions 72 are pointed protrusions.
In summary, the combination device of the present invention has the following advantages:
1) the gap G between the bottom of the electrical connector 100 and the circuit board 300 of the locking member 200 is provided with the extending portion 5, and the mounting groove 134 is provided with the limiting portion 1341 for stopping the locking member 200 from separating from the mounting groove 134 downward, that is, the electrical connector 100 cannot separate from the locking member 200 upward, so that when the base portion 4 of the locking member 200 is mounted to the mounting groove 134 and the through hole 8c is sleeved outside the connecting pin 6, and the circuit board 300 abuts against the extending portion 5 upward, because the extending portion 5 extends downward from the base portion 4, the included angle α is inevitably formed between the extending portion 5 and the bottom of the electrical connector 100, and the upward abutting force applied by the circuit board 300 to the extending portion 5 can make the included angle α smaller to drive the connecting pin 6 to swing and rotate toward the side away from the fence 135, since the extension portion 5 and the fastening portion 7 are located on the same side of the connecting pin 6 in the transverse direction Y, the fastening portion 7 can rotate and swing towards a side away from the partition 135 along with the extension portion 5, and further the fastening portion 7 can be effectively disposed below the bottom surface 8b of the circuit board 300 to stop the fastening portion 7 from moving upward, that is, the fastening portion 7 can be used to stop the circuit board 300 from moving downward. It can be seen that the upward abutting force applied by the circuit board 300 to the extension portion 5 can effectively ensure that the locking member 200 can rotate and swing, so that the locking portion 7 is disposed below the bottom surface 8b of the circuit board 300 to prevent the circuit board 300 from moving downward, and the electrical connector 100 cannot be separated from the locking member 200 upward.
2) Since the position-limiting portion 1341 and the blocking portion 1351 are located on two opposite sides of the main body 41 in the transverse direction Y, the main body 41 is blocked by the position-limiting portion 1341 in the transverse direction Y, and the protrusion 42 away from the extension portion 5 is blocked by the blocking portion 1351 in the transverse direction Y, so that the locking member 200 is respectively blocked by the position-limiting portion 1341 and the blocking portion 1351 located on two opposite sides of the main body 41 in the transverse direction Y, and the locking member 200 is limited to move only between the position-limiting portion 1341 and the blocking portion 1351 in the transverse direction Y.
3) Since the blocking portion 1342 and the limiting portion 1341 are located on the upper and lower sides of the connecting portion 43 in the up-down direction Z, the turning portion 433 of the connecting portion 43 is blocked by the blocking portion 1342 in the up-down direction Z, and the supporting portion 44 disposed at the end of the connecting portion 43 is blocked by the limiting portion 1341 in the up-down direction Z, the locking member 200 is respectively blocked by the blocking portion 1342 and the limiting portion 1341 located on the opposite sides of the connecting portion 43 in the up-down direction Z, so that the locking member 200 is limited to move only between the blocking portion 1342 and the limiting portion 1341 in the up-down direction Z.
4) Since the protrusion 42 extends upward from the body 41 and is configured to abut against the stop portion 1351 in the transverse direction Y, and the extension portion 5 extends downward from the body 41 in the transverse direction Y toward a direction away from the protrusion 42, and the extension portion 5 is disposed below the limit portion 1341, when the circuit board 300 applies an upward abutting force to the extension portion 5, the protrusion 42 can rotate toward a side close to the barrier 135 in the transverse direction Y, and since an included angle formed between the extending direction of the protrusion 42 and the extending direction of the extension portion 5 is an obtuse angle, the protrusion 42 can abut against the stop portion 1351 as soon as possible after the body 41 can rotate between the limit portion 1341 and the stop portion 1351 by a smaller angle.
5) Since the connecting portion 43 extends upward from the body portion 41 and then bends downward to extend to connect with the supporting portion 44, the supporting portion 44 is disposed in a hooking manner, so that the supporting portion 44 abuts against the limiting portion 1341 from top to bottom, and the fastening member 200 can be effectively prevented from separating from the mounting groove 134 downward, and the supporting portion 44 and the protruding portion 42 are respectively disposed at two sides of the connecting portion 43, and the protruding portion 42 and the connecting portion 43 are disposed at an interval in the transverse direction Y, so that when the body portion 41 rotates in the transverse direction Y to a side far from the barrier 135, the supporting portion 44 can abut against the limiting portion 1341, and when the body portion 41 rotates in the transverse direction Y to the barrier 135, the protruding portion 42 can abut against the stopping portion 1351.
6) Since the position-limiting portion 1341 and the stopping portion 1351 are located on two opposite sides of the main body 41 in the transverse direction Y, the connecting portion 43 and the protruding portion 42 respectively extend upward from the main body 41, and the connecting portion 43 is disposed near the position-limiting portion 1341, and the protruding portion 42 is disposed near the stopping portion 1351, so that when the circuit board 300 abuts the extending portion 5 upward, the locking member 200 at least can alternatively realize that the supporting portion 44 abuts the position-limiting portion 1341 or the protruding portion 42 abuts the stopping portion 1351.
7) Since the included angle between the extension portion 5 and the connection pin 6 is an acute angle, and the buckling portion 7 and the connection pin 6 are acute angles, it can be seen that the extension direction of the extension portion 5 and the extension direction of the buckling portion 7 intersect with each other at the same side of the connection pin 6, which is convenient for the extension portion 5 and the buckling portion 7 to block the circuit board 300 in the up-down direction Z in an up-down limiting manner.
8) The fastening part 7 is obliquely and downwardly extended from the connecting pin 6, an included angle between the connecting pin 6 and the fastening part 7 is an obtuse angle, and a plurality of protrusions 72 are arranged along an extending direction of the fastening part 7, and the connecting part 8d of the bottom surface 8b and the through hole 8c of the circuit board 300 is mutually fastened with one of the protrusions 72, so that when the circuit board 300 is subjected to a downward acting force, one of the protrusions 72 inevitably gives an upward blocking force to the circuit board 300, and the circuit board 300 is prevented from moving downward, that is, the fastening part 7 is blocked from moving upward.
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 technical changes that can be made by applying the present specification and the drawings are included in the scope of the present invention.
