Detailed Description
The following further describes embodiments of the present invention with reference to the drawings.
As shown in fig. 2 and fig. 3, first, the stress condition after the plug 100 and the socket 200 are plugged in the prior art is analyzed, as shown in fig. 2, after the plug housing 11 with the lock pin 12 moves toward the socket 200, the rotating shaft 9 drives the lock hook 6 to rotate, and the hook groove in the lock hook 6 cooperates with the lock pin 12 to achieve the locking of the plug 100 and the socket 200. After locking, the latch 12 is subjected to a force F provided by the latch hook 6 towards the plug 100nThe latch hook 6 is subjected to a counter-force F provided by the latch 12 towards the socket 200n´。
When the socket is used, the probe is usually connected to the plug 100, the host is usually connected to the socket 200, the probe is held by a person to operate, at the moment, inevitably, the probe can generate a tensile force effect on the plug 100, the acting force can be transmitted to the lock pin 12 after the plug 100 is pulled, the lock pin 12 is transmitted to the lock hook 6, the lock hook 6 is sleeved on the rotating shaft 9 in a rotation stopping manner, and the rotating shaft 9 can be subjected to the action of FxThe rotary shaft 9 is pressed against the socket housing 1 by the insulator 7 so that both edges of the insulator 7 are subjected to FxThe force of (2). As can be seen from the description of the background art, in the prior art, the insulator 7 is fastened to the socket housing 1 by the intermediate screw 8, and the fastening force F is applied to the insulator 7 by the screw 8xTherefore, in use, when the plug 100 is pulled, the insulator 7 is subjected to a torque M, which causes large deformation of both edges of the insulator 7 after long-term use, and the deformation of the insulator 7 causes the rotation shaft 9 to be unable to compress, which easily causes loose fitting between the plug and the socket. In addition, after the plug and the socket are loosened, in fact, the plug contact on the plug can move along with the plug, so that the contact position between the plug contact and the socket contact is changed, the situation that signals and/or electricity transmission are unstable is easy to occur, after the plug is used for a long time, the insulator can be damaged, the headstock assembly cannot be used continuously, and the mechanical life of a product is influenced.

Specific embodiments of the header assembly of the present invention:
as shown in fig. 4-12, the header assembly includes a plug 400 and a receptacle 300, wherein the structure of the plug 400 is identical to that of the prior art, and the plug 400 includes a plug housing and plug contacts 41. The receptacle 300 includes a receptacle housing 39, wherein, as shown in fig. 7 and 8, the receptacle housing 39 includes a housing main body 31 and support walls 32, the housing main body 31 is integrally formed in a box-shaped structure, the support walls 32 are integrally formed with the housing main body 31, and the support walls 32 are arranged at intervals of two along the length direction of the housing main body 31. The structure of the supporting wall 32 is shown in fig. 8, 9 and 10, and the supporting wall 32 has two arc-shaped grooves for the spindle 36 to be inserted into and limit the spindle 36. The two arc-shaped grooves are arranged at intervals along the radial direction of the rotating shaft 36, and a threaded hole 310 is formed between the two grooves.
As shown in fig. 5 and 6, the socket 300 further includes socket contacts 313 arranged in the socket housing 39, and the specific structure thereof is identical to that in the prior art and will not be described herein again.
The socket 300 further includes a rotating shaft assembly capable of driving the socket contacts 313 to be offset and enabling locking between the socket 300 and the plug, wherein the rotating shaft assembly is of an existing structure. The rotating shaft assembly specifically comprises two rotating shafts 36, the two rotating shafts 36 are arranged in parallel, the two rotating shafts 36 are in meshed transmission through gears, a cam shaft is further sleeved outside the rotating shafts 36 in a rotation stopping manner, and the cam shaft drives the socket contact piece 313 to deflect after rotating. A locking hook 35 is further sleeved outside the rotating shaft 36 in a rotation stopping manner, and a hook groove is formed in the locking hook 35 and can be matched with a locking pin on the plug to realize locking of the plug and the socket.
As shown in fig. 7 and 11, the socket 300 further includes an insulator 33, wherein the overall structure of the insulator 33 is the same as that in the background art, and is not described herein again. The insulator 33 has two arcuate recesses at one end for mating with the receptacle housing 39 to cooperatively locate the shaft 36. A screw hole 38 is formed at a middle position of the two grooves, and the screw hole 38 can be penetrated by the screw 37.
When assembling, after the rotating shaft assembly is placed on the supporting wall 32 of the socket housing 39, the insulator 33 is pressed on the supporting wall 32, and then the insulator 33 is fixedly mounted on the socket housing 39 by passing the screw 37 through the screw through hole 38 and the screw hole 310, thereby limiting the rotating shaft 36.
In the present invention, in order to reduce the tilting of the edge of the insulator 33, even to prevent the edge of the insulator 33 from tilting, thereby affecting the signal and/or electrical transmission stability and causing looseness between the plug and the socket. As shown in fig. 11, four barbs 34 are provided on a side surface of the insulator 33 facing the receptacle housing 39, the barbs 34 are integrally formed on the side surface of the insulator 33, and the barbs 34 are cantilevered by a predetermined length so that the barbs 34 can elastically swing by a predetermined amount. As shown in fig. 11, the end of the barb 34 has a hook head, and the hook head has an inclined surface, so that the barb 34 can swing automatically after contacting the supporting wall 32, and can extend into the barb locking groove 312 when swinging back.
As shown in fig. 11, the four barbs 34 are arranged in a rectangular shape, the positions of the barbs 34 correspond to the positions of the screw through holes 38, two barbs 34 are respectively arranged at two sides of the screw through holes 38, and the two barbs 34 are located in the radial direction of the screw through holes 38 and arranged in a straight line between the screw through holes 38 and the screws 37 which are subsequently threaded. As can be seen in fig. 11, the barbs 34 are located at the edge of the insulator 33. Two barbs 34 on the same side edge can form a pulling structure, and the edge on the side is pulled to prevent the tilting deformation.
In order to engage the barbs 34, in the present embodiment, when the housing main body 31 and the supporting wall 32 are integrally formed, an insertion passage 311 is left between the two for inserting the barbs 34, and at the same time, a barb locking groove 312 is opened on the side of the supporting wall 32 facing the housing main body 31 for engaging with the hook head of the barbs 34.
In use, the barbs 34 are inserted into the insertion channels 311 along with the insulator 33 and snap into the barb lock grooves 312 after spring back. The force diagram in use is shown in fig. 7, and it can be seen from fig. 7 that, in actual use, when the plug is pulled, the force F applied to the plug is still applied to the edge of the insulator 33 through the locking pin, the locking hook 35 and the rotating shaft 361At this time, due to the engagement of the barb 34 and the barb lock groove 312, the insulator 33 is pulled to drive the barb 34 to move toward the plug, and the barb lock groove 312 is aligned with the barb 34Applying a counter-acting force F2Through F2The acting force of the insulator 33 towards the plug is counteracted, and the phenomenon that the edge of the insulator 33 is easy to deform due to the fact that the acting force is too large in one direction is avoided.
In this embodiment, in order to ensure that the insulator 33 can be stably supported when being installed in the receptacle housing 39, as shown in fig. 11 and 12, a boss 314 is provided on the outside of the insulator 33, and the boss 314 can be in interference fit with the inner wall of the receptacle housing 39 to support and prevent the insulator 33 from being misaligned.
In the present embodiment, the support wall 32 and the housing main body 31 are spaced apart from each other to form the insertion passage 311, and the support wall 32 is provided with the barb lock groove 312, but in other embodiments, the barb lock groove and the insertion passage may be formed by, for example, providing the insertion passage on the inner wall of the support wall 32 and opening the barb lock groove on the wall surface. Still alternatively, the barb locking groove may be arranged on the housing main body, specifically, the wall thickness of the housing main body is increased, the barb locking groove is provided on the inner wall of the housing main body, and correspondingly, the orientation of the hook head in the lock hook needs to be turned.
Based on the idea that the barb 34 is disposed on the insulator and the barb lock groove 312 is disposed on the receptacle housing, the barb lock groove 312 and the barb 34 cooperate to apply a counterforce to the insulator, in other embodiments, the barb may be disposed on the receptacle housing and the barb lock groove may be disposed on the insulator, specifically, the barb may be disposed on the support wall, the barb extends toward the insulator, a groove may be disposed at an end of the insulator facing the receptacle housing to form an insertion passage, the barb lock groove may be disposed on a groove wall of the groove, and during installation, the insulator may be placed on the support wall and the barb lock into the barb lock groove.
In this embodiment, all the barb locking grooves are matched with the barb, and actually, the groove wall surfaces of the barb locking grooves are matched with the barb in the barb locking grooves, and the blocking relation between the barb and the groove wall surfaces is relied on, so that the barb locking grooves can be matched with the barb in a blocking way only by providing a structure of the blocking surfaces matched with the barb on the basis of the principle, and a counterforce is exerted on the insulator, and in other embodiments, the blocking surfaces can be provided by the outer peripheral surface of the lock rod.
In the embodiment, the barb corresponds to the screw in the radial direction, so that the installation is convenient, and the space on two sides of the screw through hole on the insulator is utilized for arrangement. In this embodiment, the primary fastening of the insulator to the jack housing is still the screws 37, while the presence of the barbs only serves to reduce deformation when the insulator is forced by the plug tension to provide a counter force. The barb and the corresponding barb locking groove or the locking rod form pulling pieces for pulling the insulator, the number of the pulling pieces is four, two pulling pieces located on the same side of the screw 37 form a pulling structure, and the two pulling structures respectively pull two side edges of the insulator. The two pulling structures and the two screws together form a fixed assembly.
In other embodiments, the pulling element may be fastened by screws, that is, four screw through holes are formed in the insulator, a threaded hole is formed in the supporting wall, the edge of the insulator is fixed to the supporting wall by four screws, and after the pulling element is fastened by screws, the screws on the edge can play a role in pulling the insulator, thereby forming the pulling element.
