Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments.
Examples
Fig. 2 is a schematic view showing a structure of the connector before assembling the connector in this embodiment, which includes a housing 100 and a locking assembly 200, and it can be seen in conjunction with fig. 2 that the housing 100 and the locking assembly 200 are separated in this embodiment, and the housing 100 and the locking assembly 200 are manufactured and processed separately during actual production and use, and the locking assembly 200 is assembled into the housing 100 in situ for use.
Fig. 3 is a schematic structural view of the assembled connector in this embodiment, fig. 4 is a schematic structural view of the locking assembly 200, and in combination with fig. 2, the locking assembly 200 includes a connector 210 and a locking pin 220, the connector 210 is a shaft-type part, a threaded hole 211 is provided on at least one end surface of the connector 210, a through hole perpendicular to the axial direction of the connector 210 is further provided on the connector 210, and the locking pin 220 can pass through the through hole.
Fig. 5 shows a schematic structure of a housing 100, the housing 100 having a plug face 101, the plug face 101 having an array of plug connectors 102, and the plug connectors 102 being connected to a mating plug (not shown) for signal transmission. In addition, a receiving hole 103 is provided on the plugging surface 101 of the housing 100, the receiving hole 103 is matched with the connector 210 to receive the connector 210 to be embedded in the receiving hole 103, the threaded hole 211 is exposed on the plugging surface 101 in the embedded state of the connector 210, and the through hole on the connector 210 is positioned inside the receiving hole 103; meanwhile, the housing 100 is further provided with a locking hole 104 perpendicular to the axial direction of the accommodating hole 103 and penetrating through the housing 100, the locking hole 104 penetrates through the accommodating hole 103 at the same time, so that after the connecting piece 210 is embedded into the accommodating hole 103, the locking pin 220 is inserted into the locking hole 104 again and penetrates through the through hole on the connecting piece 210, thereby locking and fixing the connecting piece 210 in the housing 100 through the locking pin 220, so that the threaded hole 211 of the connecting piece 210 is formed into a connecting structure on the housing 100, and the locking pin 220 has the functions of tightening, fixing and rotating limitation on the connecting piece 210, namely, the connecting piece 210 cannot rotate after being fixed by the locking pin 220, so that the problem that the connecting piece 210 is loose due to overlarge torsion caused by unstable connection of the connecting piece 210 in the housing (such as single processing of the connecting piece 210 and integral injection molding of the housing) can be avoided.
As shown in fig. 2, 3 and 5 of the present embodiment, a set of locking assemblies 200 is provided on the housing 100 at both sides of the connector 102, and each set of locking assemblies 200 has one locking pin 220 and two connectors 210 therein, and the locking assemblies 200 are in an "F" shape after the assembly is completed, but this is not a combination state that may be fully represented in the present embodiment, in which the number of connectors 210 is not limited to two, the number of locking pins 220 is not limited to one, the position of the connector 210 relative to the locking pin 220 is not limited to the top or bottom, and the position of the locking pin 220 relative to the connector 210 is not limited to the end, for example, several states may be also shown in fig. 6.
In addition, the locking structure of the existing connector is integrated with the shell and is independent, when the connector is used for signal transmission of the PCB, the connector is required to be separately designed with the connecting structure between the PCB or connected with the PCB in a welding and fixing mode, if the connecting structure of the additional design is adopted, the connector structure is complicated and is unfavorable for meeting the miniaturization requirement, and if the welding and fixing mode is adopted, the requirement on the assembly process is provided.
Referring to fig. 3, the connector in the present embodiment is applied to an L-type connection scenario, and the connector is integrally in an L shape, and the application of the connector can change the plugging mode perpendicular to the PCB board into the plugging mode parallel to the PCB board, so that the adjacent surface of the plugging surface 101 is provided with the contact pieces 105 in an array, and the contact pieces 105 are directly contacted with the pads on the PCB board to realize electrical conduction. On the basis, according to the above description, the locking hole 104 is formed to penetrate the housing 100, and on the basis, the length of the locking pin 220 is set to be greater than the depth of the locking hole 104, so that after the housing 100 and the locking assembly 200 are assembled, the tail end of the locking pin 220 protrudes out of the surface of the housing 100.
The design has the advantages that: on one hand, an assembly process of independently welding the contact 105 and a bonding pad on the PCB can be avoided, the contact 105 and the bonding pad on the PCB can be conducted by directly adopting a spring needle as the contact 105, and the contact is fixed with a through hole on the PCB through the locking pin 220; on the other hand, the problem that the plugging force is completely applied to the welding position of the contact 105 and the bonding pad in the plugging process caused by adopting a welding mode to weld the contact 105 and the bonding pad on the PCB can be avoided, as the number of cores of the connector is large, the welding point of the contact 105 and the bonding pad is easily damaged, and the plugging force in the plugging process is transferred to the locking pin 220 by adopting a mode of fixing the locking pin 220 and the through hole on the PCB, the strength of the locking pin 220 is higher than that of the welding point of the contact 105 and the bonding pad, and the locking pin 220 is a simple structural member, so that the connection of the connector and the PCB is greatly protected.
It should be noted that the structure of the connector for connection and fixation may be combined, for example, a threaded hole is provided on the socket, and a threaded post is provided on the plug; or a threaded post is provided on the socket and a threaded hole is provided on the plug, so that the threaded hole 211 described above may alternatively be a threaded post 213 as shown in fig. 7.
As shown in fig. 7, the through hole provided in the connector 210 for matching with the locking pin 220 may be provided as a notch 212, which is not limited to the aforementioned through hole or the notch 212 having a rectangular cross section shown in fig. 7, and the structure of matching the connector 210 with the locking pin 220 is characterized in that the locking pin 220 and the connector 210 have a partially overlapped and embedded state in the axial direction of the connector 210.
