The locker 30 is used to be coupled with the fixing hole 14, and the locker 30 is coupled with the fixing hole 14 in various ways; for example, the locking member 30 is connected with the fixing hole 14 through a screw thread, that is, the hole wall of the fixing hole 14 is provided with a screw thread section, and the outer peripheral wall of the locking member 30 is correspondingly provided with a screw thread section, so that the locking member 30 can be connected with the fixing hole 14; if the locking member 30 is connected with the fixing hole 14 by inserting, that is, the locking member 30 is tightly matched with the fixing hole 14, the connection between the locking member 30 and the fixing hole 14 can also be realized; the locking member 30 and the fixing hole 14 can be connected in other ways, which are not illustrated here.

the mode of fixing the lead 200 by the locking piece 30 is related to the size of an included angle between the axis of the wiring hole 13 and the axis of the fixing hole 14, and if the included angle between the axis of the wiring hole 13 and the axis of the fixing hole 14 is larger than 0 degree and smaller than 90 degrees, the locking piece 30 can extend into the wiring hole 13 to fix the lead 200; if the included angle between the axis of the wiring hole 13 and the axis of the fixing hole 14 is equal to 0 °, the locking piece 30 can press the wire 200 to the end face of the free end 12; the retaining member 30 may also be used to secure the lead 200 in other ways, not necessarily all.

Since the connection end 11 of the main body 10 of the terminal is fixedly connected to the housing of the socket when the terminal 100 of the socket is mounted in the socket, and the free end 12 of the main body 10 of the terminal is spaced apart from the housing of the socket, that is, after the housing of the socket is disassembled, the free end 12 of the main body 10 of the terminal is faced to the user, so that the locking member 30 engaged with the fixing hole 14 is also faced to the user. When dismantling wire 200 from the terminal, can directly loosen retaining member 30 through the instrument, this just makes can not receive the influence of installing electronic components around the socket when loosening retaining member 30 to need not to dismantle the electronic components around the socket, and then the change of the socket of being convenient for.

It should be noted that the axis of the wire connecting hole 13 is disposed at an angle to the axis of the fixing hole 14, and it is understood that the axis of the wire connecting hole 13 intersects with the axis of the fixing hole 14 or the axis of the wire connecting hole 13 is disposed parallel to the axis of the fixing hole 14.

In an embodiment of the present invention, the axis of the wiring hole 13 intersects with the axis of the fixing hole 14, that is, the axis of the wiring hole 13 and the axis of the fixing hole 14 form an included angle greater than 0 ° and less than 90 °, and considering that the wiring hole 13 and the fixing hole 14 are disposed on the same plane, the axis of at least one of the wiring hole 13 and the fixing hole 14 is disposed obliquely (that is, the axis of the wiring hole 13 and the end surface of the connecting end 11 form an included angle greater than 0 ° and less than 90 ° or the axis of the fixing hole 14 and the end surface of the free end 12 form an included angle greater than 0 ° and less than 90 °), which will affect the processing of the fixing hole 14 or the wiring hole 13, and in view of this, referring to fig. 1, the free end 12 is disposed as a first plane 11a and a second plane 11b which are connected at one time, the first plane 11a is disposed parallel to the end surface of the connecting end 11, the second plane 11b is concave towards the direction close to the connecting section 32 and forms an included angle of more than 90 degrees and less than or equal to 180 degrees with the first plane 11 a; the wiring hole 13 is provided through the first plane 11 a; the fixing hole 14 is concavely arranged on the second plane 11b and communicated with the wiring hole 13; the locker 30 is fitted into the fixing hole 14 and one end of the locker 30 is inserted into the wire-connecting hole 13 to fix the lead 200. With the arrangement, on one hand, the fixed hole 14 and the wiring hole 13 are convenient to open, namely, the axis of the fixed hole 14 is ensured to be vertical to the end surface of the connecting end 11 and the first plane 11a, and the axis of the wiring hole 13 is vertical to the second plane 11 b; on the other hand it is ensured that the locking member 30 is always exposed from the free end 12 of the body 10.

it should be noted that, since the angle between the first plane 11a and the second plane 11b is greater than 90 ° and less than or equal to 180 °, the angle between the first plane 11a and the second plane 11b can be 105 °, 130 °, 145 °, 160 °, 180 °, and so on, which allows the angle between the first plane 11a and the second plane 11b to be set according to actual needs. Preferably, the angle α between the first plane 11a and the second plane 11b is set to be greater than or equal to 120 ° and less than or equal to 160 °. With this arrangement, the fixing holes 14 concavely formed on the second plane 11b can be sufficiently exposed, thereby facilitating the locking and releasing of the locking member 30.

Further, referring to fig. 2, an end of the locking member 30 extending into the wire connecting hole 13 is provided with a relief hole 31 for the lead 200 to pass through. In this way, when fixing the guide wire 200, especially the flexible guide wire 200, the guide wire 200 can be firstly passed through the offset hole 31 of the locking member 3020, and then the guide wire 200 can be wound on the locking member 3020 by rotating the locking member 30 so as to follow the rotation of the locking member 30, thereby fixing the guide wire 200 more firmly.

In an embodiment of the present invention, please refer to fig. 3, an axis of the wiring hole 13 is parallel to an axis of the fixing hole 14, that is, the axis of the wiring port and the axis of the fixing hole 14 form an included angle of 0 °, and the wiring hole 13 and the fixing hole 14 are spaced; the locking member 30 comprises a connecting section 32 and a locking section 33 projecting laterally from the connecting section 32. When the lead wire 200 is fixed, the connecting section 32 is engaged with the fixing hole 14, and the locking section 33 presses the lead wire 200 against the end face of the free end 12. So configured, the wire 200 is also easily secured and removed.

It should be noted that, there are many connection manners between the connection section 32 and the fixing hole 14, for example, the connection section 32 and the fixing hole 14 are fixed by screw connection, that is, the outer peripheral wall of the connection section 32 is provided with a screw thread section extending along the axial direction thereof, and the inner wall surface of the fixing hole 14 is provided with a screw thread section extending along the axial direction thereof, so that the screw connection between the connection section 32 and the fixing hole 14 can be realized; for another example, the connection section 32 and the fixing hole 14 are connected and fixed in an inserting manner, that is, the connection section 32 and the fixing hole 14 are connected in a tight fit manner; the connecting section 32 can also be connected to the fixing hole 14 in other ways, which are not listed here.

Further, the locking section 33 is disposed in a disk shape extending along the circumferential direction of the connecting section 32, and the radius of the locking section 33 is larger than the maximum distance between the wire connecting hole 13 and the fixing hole 14. By the arrangement, the radial cross-sectional area of the locking section 33 in the connecting section 32 is increased, so that the locking section 33 can press the wire 200 to the end face of the free end 12 when the connecting section 32 is connected with the fixing hole 14, and the problem that the locking section 33 cannot press the wire 200 to the end face of the free end 12 well due to the fact that the radial area of the locking section 33 in the connecting section 32 is too small is avoided.

Further, referring to fig. 4 and 5, the end face of the free end 12 is recessed with a wiring groove 15 communicating with the wiring hole 13 and/or the surface of the locking section 33 facing the free end 12 is recessed with a wiring groove 34 extending in the radial direction of the connecting section 32. So arranged, on the one hand, to facilitate the fixing of the wire 200 to the free end 12 face; on the other hand, the problem that the outer layer of the lead 200 is damaged due to overlarge pressure applied to the lead 200 can be avoided, so that the safety performance is improved.
