Abstract
The utility model relates to a connector used for connecting with PCB plate, which comprises a bulk, a contact pin connected on the bulk and a guide finger, wherein the guide finger is provided with impaction pins which are interferingly fitted with the connecting hole of the PCB plate, and the external surfaces of the impaction pins are provided with protruding ribs. Making use of the impaction pins, it is possible to install the connector and the guide finger of the PCB plate with one impaction, thereby simplifying the process. In the meanwhile, the replacement of screw fastening in the prior art by the impacted metal guide finger makes the spatial pattern of the PCB plate back more flexible, which can prevent the interference among the components. Besides, the destruction to the contact pin is prevented, thereby enhancing the reliability of the installation of components and the PCB.
Description
Technical field
The utility model relates to a kind of connector, more specifically, relates to a kind of connector that is connected with pcb board.
Background technology
Along with the development that the communication technology is advanced by leaps and bounds, the integrated level of equipment is more and more higher, the capacity of equipment is increasing, and the interface between feature board and the backboard is more and more, needs the more connector of layout in limited space.Be extensive use of 2mmHM-D type connector at present in communication equipment, the pin of this connector is thinner, and looper falls pin easily, causes the system failure.2mmHM-D type connector has the metal guide finger, can insert by correct position by guidance connector, thereby makes 2mmHM-D type connector possess good guidance quality.But what the mount scheme of the metal guide finger of 2mmHM-D type connector adopted at present is the screw fastening means, and not only assembling is complicated, also can interfere with other device during trip bolt, also damages the pin of connector simultaneously easily.
Fig. 1 is the schematic diagram of connector metal guide finger of the prior art.As shown in Figure 1, the metal guide finger of the 2mmHM-D type connector that extensively adopts uses screw to carry out fastening at present.Have contact pin 11 on the connector 1, and be connected with pcb board 10 with nut 13 by metal guide finger 12.
Usually, finish two operations of installment work needs of connector: crimp connector and installation metal guide finger.Its shortcoming is: need shimming and nut when the metal guide finger is installed, the assembling process complexity causes that production efficiency is low, cost is high; When the trip bolt of the connector back side, may interfere, only under the bigger situation of arrangement space, be suitable for other adjacent devices; Long with the metal guide finger that screw-type is fastening, if buckle need be installed in the connector back side, then can influence the layout of buckle; In addition, behind the intact connector of crimping, the fastening metal guide finger causes the connector looper easily, influences the reliability of connector.
The utility model content
The technical problems to be solved in the utility model is, low at the metal guide finger of 2mmHM-D type connector in prior art assembling difficulty, production efficiency, interfere with connector back side device and make defective such as connector looper easily, provide a kind of and PCB assembling simple, be connected reliable connector, can enhance productivity simultaneously.
The technical scheme that its technical problem that solves the utility model adopts is: construct a kind of connector of being connected with pcb board of being used for, comprise body, be connected contact pin and guide finger on the body, wherein, described guide finger has the crimping pin with the connecting hole interference fit of pcb board.
At the connector that is connected with pcb board of being used for described in the utility model, described crimping pin outer surface is provided with fin.
At the connector that is connected with pcb board of being used for described in the utility model, described fin is the annular knurl fin.
At the connector that is connected with pcb board of being used for described in the utility model, the crimping pin of described guide finger links to each other with guide end by boss.
At the connector that is connected with pcb board of being used for described in the utility model, be provided with groove milling in the junction of crimping pin and boss.
At the connector that is connected with pcb board of being used for described in the utility model, the end of described crimping pin is provided with chamfering.
Implement connector of the present utility model, have following beneficial effect: utilize the crimping pin that connector is fixed on the pcb board, do not need to carry out the operation of trip bolt, can simplify assembling procedure, enhance productivity.Simultaneously, use the metal guide finger of crimp type to replace the fastening mode of screw, the arrangement space at the pcb board back side more can not cause the interference between the device.In addition, the metal guide finger of compression joint type has been avoided the damage to the connector stitch, has improved the reliability of device and PCB assembling.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the schematic diagram of connector metal guide finger of the prior art;
Fig. 2 is the schematic diagram of crimp type metal guide finger of the present utility model;
Fig. 3 is the schematic diagram of connector of the present utility model.
Embodiment
Fig. 2 is the schematic diagram of crimp type metal guide finger of the present utility model.As shown in Figure 2, this metal guide finger 2 comprises columniform guide end 21 and columniform crimping pin 24, and both connect by square boss 22, are provided with groove milling 23 in the junction of crimping pin 24 and boss 22.Groove milling 23 can be adopted to bore to mill or coil and mill, and is convenient to guide finger 2 and more successfully is connected with pcb board.The outer surface of cylindrical crimping pin 24 is evenly distributed with fin, as the annular knurl fin; And the end of crimping pin 24 has chamfering 25.
Fig. 3 is the schematic diagram of connector of the present utility model.As shown in Figure 3, connector 3 comprises body 31, is connected contact pin 32 and metal guide finger 2 on the body 31.The crimping pin 24 of metal guide finger 2 is crimped onto in the metal connecting hole on the PCB, forms interference fit by the distortion of fin and the metal connecting hole of pcb board.Simultaneously, boss 22 guarantees connector 3 firm positions, reliable.
In the utility model, can adopt suitable mold that metal guide finger 2 and connector 3 are carried out crimping simultaneously, not need to carry out the operation of trip bolt, can simplify assembling procedure, enhance productivity.Simultaneously, use the metal guide finger of crimp type to replace the fastening mode of screw, and shortened the length of metal guide finger, the arrangement space that makes the pcb board back side more can not cause the interference between the device.In addition, the metal guide finger of compression joint type has been avoided the damage to the connector stitch, has improved the reliability of device and PCB assembling.
