Description
Technical Field
The utility model relates to a point connector technical field, in particular to small-size electric connector structure.
Background
With the design and development of the inertial navigation device, miniaturization is a development trend, and the volume requirement of the aviation product based on the optical fiber inertial navigation device is smaller and better. With the continuous reduction of the volume of the housing of the inertial navigation device, higher requirements are put on the installation and the design of the electrical connector. The electric connector in the prior art cannot meet the requirement of miniaturization development of products more and more because the reduction of the volume of the installation shell cannot be considered during the design and the limitation of the installation operation space.
Disclosure of Invention
The technical problems solved by the invention are as follows: the utility model provides a miniaturized electric connector structure, solves the installation problem of electric connector under limited operating space among the prior art through structural design.
The technical scheme of the invention is as follows: the utility model provides a small-size electric connector structure, electric connector structure include casing, printing board and electric connector, electric connector include contact pin and jack, the contact pin fix on the printing board, electric connector pass through a mounting screw and fix on the casing. Compared with the prior art, the technical scheme has the advantages that the electric connector is simply and conveniently connected and fixed with the printed board, the electric connector and the shell are simplified and installed, and the technical problem that the installation space is limited after the shell is miniaturized is solved.
Preferably, the electric connector is provided with a threaded hole which is through up and down, and the printed board is fixed with the electric connector through the matching of the second mounting screw and the threaded hole. According to the technical scheme, the printed board and the electric connector are fixed, the through bolt hole which can be used at two ends is ingeniously formed in the electric connector, the same structure for mounting and sharing the external connection equipment and the printed board is achieved, the structure is simplified, and the size is reduced.
Preferably, the electrical connector comprises at least one pin which is lap jointed with the shell for power supply.
Preferably, the electrical connector further comprises a strap, the strap is sleeved on the contact pin, and the cross-linked housing and the contact pin are connected. This technical scheme has avoided designing special overlap joint structure, make full use of the function of contact pin, directly utilize contact pin and equipment casing overlap joint, ingenious structural design can enough realize the purpose of optimizing equipment electromagnetic compatibility, does not increase electric connector's occupation space again.
Preferably, the electric connector structure further comprises a conductive sealing gasket, and the conductive sealing gasket is sleeved on the first mounting screw and tightly attached to the end face of the shell. The conductive sealing gasket is compacted on the equipment shell, plays a role in conducting electricity, connecting the shell and sealing, does not increase extra space compared with a common gasket, and ingeniously realizes multiple functions.

Detailed Description
The invention will be further described with reference to the accompanying drawings and specific embodiments:
as shown in fig. 1, in the structure of the small-sized electrical connector, the electrical connector adopts a tail end direct-insertion printed board 9, is fixedly installed on a panel of a shell of the equipment, is installed behind the board, and is installed from the front of the panel due to limited space. The electric connector comprises a shell 1 of the electric connector, a jack 3, a threaded hole 2, a first mounting screw 4, a conductive sealing gasket 5, a second mounting screw 7, a contact pin 6, a lap joint sheet 8 and a printed board 9.
The electric connector is positioned in a shell 1, and the shell 1 is made of metal materials. The number of the jacks 3 is a plurality of, the jacks are distributed in two rows in sequence in an insulator of the electric connector, and the tail ends of the jacks are fixedly connected by contact pins 6; the threaded hole 2 is vertically communicated, and the second mounting screw 7 is matched with one end of the threaded hole 2 to fix the printed board 9 and the electric connector. The electric connector structure also comprises other external connection structures, and the other external connection structures are matched with the other ends of the threaded holes 2 through screws to realize fixation. One end of the contact pin 7, which is close to the shell, is provided with a lapping plate 8 with the shell, so that the inside is electrified with the shell; the conductive sealing gasket 5 is positioned on the end face of the electric connection panel.
During installation and use, a bottom contact pin is directly inserted into a printed board, the second mounting screw 7 is screwed up for fixation and then welding is carried out, then the electric connector is installed on the equipment shell and fixed by the first mounting screw 4, meanwhile, the conductive sealing gasket 5 is compacted on the equipment shell to play a role in conduction, shell connection and sealing, and only the appearance shown in figure 5 is seen from the outside of the equipment, so that the printed board is small and exquisite, and the space is saved.
