As shown in fig. 2, 4 and 9, each of the mounting portions 14 is pivotally connected to one of the locking members 3, the mounting groove 141 receives the corresponding locking member 3, and the locking member 3 has a locking portion 31, a pushing portion 32 and a main portion 33 connecting the locking portion 31 and the pushing portion 32.

A pivot 331 protrudes from each of two laterally opposite side surfaces of the main body 33 along the lateral direction, and the pivot 331 is correspondingly pivoted to the pivot hole 1421 of the side wall 142, so that the locking element 3 rotates between a locking position and an unlocking position. Referring to fig. 9 and 12, when the locking element 3 is located at the locking position, the locking portion 31 is engaged with the notch 2021 of the mating element 200 to lock the mating element 200, and when the locking element 3 is located at the unlocking position, the pushing portion 32 pushes the mating element 200 upward in the opposite direction (i.e., upward) to the plugging direction, so that the locking portion 31 is disengaged from the notch 2021, and the mating element 200 moves upward to be disengaged from the contact with the conductive terminal 2.

As shown in fig. 2, 4 and 6, each of the mounting portions 14 is provided with one of the detecting devices 4, each of the detecting devices 4 includes two detecting terminals 41 and one conductive member 42, the two detecting terminals 41 and the conductive member 42 are independent of each other and are made of a metal material, the conductive member 42 is fixed to the locking member 3, and the two detecting terminals 41 are fixed to two side walls 142 of the same mounting portion 14 and are located on two opposite sides of the locking member 3 in the transverse direction. Of course, in other embodiments, only one of the mounting portions 14 may be provided with one of the detecting devices 4, and the other mounting portion 14 is not provided with the detecting device 4. In this embodiment, the conductive member 42 is assembled to the locking member 3, and the detecting terminal 41 is assembled to the side wall 142, but in other embodiments, the conductive member 42 may be injection molded together with the locking member 3, and the detecting terminal 41 may be injection molded together with the body 1.

As shown in fig. 2, 4 and 6, each of the detecting terminals 41 has a fixing portion 411, an elastic arm 412 extending from the fixing portion 411 in a bending manner along a longitudinal direction, and a solder leg 413 extending from the fixing portion 411 in a plugging direction, the fixing portion 411 is fixed to the corresponding fixing groove 1424 of the side wall 142, the solder leg 413 is used for being soldered to the circuit board 300, the elastic arm 412 is used for elastically abutting against the conductive member 42 and corresponding to the relief groove 1422 on the side wall 142 for providing a relief space for elastic deformation of the elastic arm 412, and the elastic arm 412 has a guiding portion 4121 contacting the conductive member 42. In this embodiment, the fixing element 5 is through-hole soldered to the circuit board 300, and the solder leg 413 is through-hole soldered to the circuit board 300, but in other embodiments, the fixing element 5 and the solder leg 413 may also be plane-soldered to the circuit board 300.

As shown in fig. 6, 8 and 9, the conductive member 42 has a base 421 and a plurality of holding portions 422 formed by extending from the base 421, and the holding portions 422 are held on the locking member 3 along the longitudinal direction, so that the conductive member 42 is stably fixed on the locking member 3. The base 421 extends along the transverse direction and two opposite sides of the base are exposed outside the locking element 3, and the detection terminal 41 is in contact with the base 421 when the locking element 3 is in the locking position. The base 421 may be protruded outward or recessed inward or flush against the opposite surfaces of the locking piece 3 in the lateral direction as long as it is ensured that the detection terminal 41 can stably contact the base 421. The surface of the locking element 3 away from the slot 12 in the longitudinal direction is recessed to form a fixing slot 34 for accommodating the conductive member 42. When the locking member 3 is rotated to the locking position, the position where the detection terminal 41 contacts the conductive member 42 is farther from the mating surface 11 than the pushing surface 321 in the inserting direction. With such an arrangement, the influence of the fixing groove 34 on the strength of the pushing portion 32 can be reduced, and the contact position between the conductive member 42 and the detection terminal 41 is entirely close to the mounting surface 144, so that the detection terminal 41 can be mounted conveniently without affecting the arrangement of the pivot hole 1421.

As shown in fig. 2, 4 and 8, the detecting terminal 41 is fixed to the sidewall 142, and the fixing element 5 is fixed to the end wall 143. The locking fastener 3, detect terminal 41 with the mounting part 5 all is fixed in the installation department 14, just detect the position of terminal 41 and can not occupy the position of mounting part 5, be favorable to make full use of the space of installation department 14 makes body 1 is stably fixed in circuit board 300. Moreover, the elastic arm 412 of the detecting terminal 41 is formed by extending from the fixing portion 411 in a direction away from the slot 12 along the longitudinal direction, so that the position of the solder leg 413 is away from the fixing member 5, and thus the hole on the circuit board 300 corresponding to the solder leg 413 and the hole corresponding to the fixing member 5 are not too close to each other, which increases the difficulty in manufacturing the hole on the circuit board 300.

As shown in fig. 8 and 9, when the locking member 3 is rotated to the locking position, the locking portion 31 is used for locking the abutting member 200 inserted into the insertion slot 12, and the two detection terminals 41 respectively contact the conductive member 42 in the transverse direction to be electrically connected with each other; as shown in fig. 11 and 12, when the locking member 3 rotates to the unlocking position, the pushing portion 32 is used for pushing the abutting member 200 in a direction opposite to the plugging direction, and the two detection terminals 41 are separated from the contact with the conductive member 42. When the locking member 3 is located at the locking position and locks the mating member 200, the electrical connector 100 is in a conducting state; when the locking member 3 is located at the open position and the opposite member 200 is not locked, the circuit is in the off state. Thereby reducing the risk of short-circuit damage to the mating member 200 and improving the safety of the electrical connector 100. The two detection terminals 41 respectively contact the conductive member 42 in the transverse direction, the direction of the force applied by the detection terminals 41 to the locking member 3 is mainly the transverse direction, and the detection terminals 41 do not have the force applied by the locking member 3 rotating toward the open position, so that the contact between the detection terminals 41 and the conductive member 42 is stable.

As shown in fig. 7, 8 and 11, in the same mounting portion 14, the distance S1 between the fixing portions 411 of the two detection terminals 41 in the transverse direction is greater than the length L of the base portion 421 extending in the transverse direction, the distance S2 between the lead portions 4121 of the two detection terminals 41 in the transverse direction is less than the length L of the base portion 421 extending in the transverse direction, when the locking element 3 is in the locking position, the locking element 3 protrudes into between the two guiding parts 4121, and the lead parts 4121 of the two detection terminals 41 contact opposite sides of the base 421 in the lateral direction, the conductive members 42 have an outward force in the lateral direction against both the guide portions 4121, the two guide portions 4121 further stably contact opposite sides of the conductive member 42 in the lateral direction due to the elastic restoring force of the elastic arm 412.

As shown in fig. 13 and 14, before the locking member 3 is released from locking the mating member 200, the pushing portion 32 moves a distance in a direction opposite to the plugging direction, and the detecting terminal 41 is not released from contact with the conductive member 42, when the locking member 3 is just released from locking the mating member 200, the detecting terminal 41 is released from contact with the conductive member 42, that is, the limit of starting non-contact between the detecting terminal 41 and the conductive member 42 is that the locking member 3 is released from locking the mating member 200. Of course, before the locking member 3 is separated from the lock of the mating member 200, in order to further reduce the risk that the mating member 200 is inclined to cause short circuit between one of the conductive terminals 2 and two adjacent contacts 201, so that the detecting terminal 41 and the conductive member 42 are not contacted as soon as possible, specifically, the locking member 3 is rotated 4.2 degrees from the locking position to the unlocking position, at this time, the mating member 200 is displaced 0.32mm in the direction away from the plugging direction, and at this time, the conductive terminal 2 on one side of the locking member 3 which is rotated is separated from the contact with the corresponding contact 201, so that the contact between the detecting terminal 41 and the conductive member 42 on the side corresponding to the locking member 3 is disconnected, and the power is cut off in time. The detecting terminal 41 does not get out of contact with the conductive member 42 due to the very slight movement of the abutting member 200, but gets out of contact with the conductive terminal 2 in time when the abutting member 200 gets out of the latch control of the latch member 3 or the conductive terminal 2 has a risk of short-circuiting with two adjacent contacts 201, thereby improving the accuracy of power-off while ensuring the safety of the electrical connector 100.

In summary, the electrical connector of the present invention has the following advantages:

1. when the locking member 3 is rotated to the locking position, the locking portion 31 is used for locking the abutting member 200 inserted into the insertion slot 12, and the two detection terminals 41 respectively contact the conductive member 42 in the transverse direction to be electrically connected with each other; when the locking member 3 rotates to the unlocking position, the pushing portion 32 is used for pushing the abutting member 200 in a direction opposite to the plugging direction, and the two detection terminals 41 are separated from the contact with the conductive member 42. So that the electrical connector 100 is in a conducting state when the locking member 3 is located at the locking position and locks the mating member 200; when the locking member 3 is located at the open position and the opposite member 200 is not locked, the circuit is in the off state. Thereby reducing the risk of short-circuit damage to the mating member 200 and improving the safety of the electrical connector 100.

2. When the locking member 3 rotates to the locking position, the two detection terminals 41 respectively contact the conductive member 42 in the transverse direction, the direction of the force applied to the locking member 3 by the detection terminals 41 is mainly the transverse direction, and the detection terminals 41 do not have the force applied to the locking member 3 by rotating toward the opening position, so that the contact between the detection terminals 41 and the conductive member 42 is stable.

3. Before the locking member 3 is separated from the locking of the mating member 200, the pushing portion 32 moves a distance in a direction opposite to the plugging direction, and the detecting terminal 41 is not separated from the contact with the conductive member 42, and when the locking member 3 is just separated from the locking of the mating member 200, the detecting terminal 41 is separated from the contact with the conductive member 42. The detecting terminal 41 does not get out of contact with the conductive member 42 due to the very slight movement of the abutting member 200, but gets out of contact with the conductive terminal 2 in time when the abutting member 200 gets out of the latch control of the latch member 3 or the conductive terminal 2 has a risk of short-circuiting with two adjacent contacts 201, thereby improving the accuracy of power-off while ensuring the safety of the electrical connector 100.

4. It is only one the installation department 14 sets up detection device 4, another do not set up on the installation department 14 detection device 4, when not setting up detection device 4 one side the rotatory certain angle of hasp piece 3 has set up detection device 4 one side when hasp piece 3 is not rotatory, butt joint piece 200 slope, rotatory one side of hasp piece 3 does not set up detection device 4 can not detect and produce the outage signal and make electric connector in time cut off the power supply.
