Electromagnetic coupling device.
Background technique
Small-caliber anti aircraft gun radio frequency is high, reaches 400 hairs/second, and the passive setter of adapted requires to complete in a very short period of time
Wireless charging and Information loading, in order to reliably set, wireless charging and Information loading are down in 10 milliseconds, and this fuse fills
To determine device and belong to cannon intellectualized reconstruction project, can be only positioned at existing small space, it is extremely low that induction sets electromagnetic coupling rate, in order to
It improves wireless induction and sets efficiency, existing small space can only be maximally utilised, improve electromagnetic coupling strengths, reach raising
The purpose of electromagnetic coupling efficiency.
Summary of the invention
The object of the invention is exactly and to provide to overcome the shortcomings of above-mentioned background technique and a kind of passive set electromagnetic coupling dress
It sets, makes full use of existing space, using special-shaped magnetic core and double transmitting coils, improve electromagnetic coupling strengths.
It is according to the present invention it is passive set electromagnetic coupling device, by attachment base 1, supporting case 2, support box cover 3, special-shaped magnetic
Core 6, transmitting coil 5 and potting compound 4 form, and attachment base 1 is formed by intermetallic composite coating, and supporting case 2 and support box cover 3 are by nonmetallic multiple
Condensation material injection molding, the special-shaped die sinking of magnetic core 6 customization, transmitting coil 5 are formed by coiling fixation；Device assembling process is: first
First two groups of transmitting coils 5 are wound on the special-shaped magnetic core 6 processed by tooling, are fixed with Instant cement, then by coiling
The special-shaped magnetic core 6 of good coil is fixed in supporting case 2 by most beneficial for the reception received direction of line, is injected potting compound 4, is covered
Supporting case 2 etc. is to be solidified, is integrally embedded in attachment base 1 after being cured.
The present invention has the characteristics that structure is simple, it is high with versatility to be easily assembled to, and it is wireless to efficiently solve 25 variable-time fuses
Induction sets the problem of electromagnetic coupling low efficiency, improves fuse Information loading reliability.

Embodiment
The present embodiment is the present invention application for setting electromagnetic coupling passive to 25 variable-time fuses.Its form as shown in Figure 1, Figure 2,
Shown in Fig. 3, Fig. 4, Fig. 5, the device is by attachment base 1, supporting case 2, support box cover 3, special-shaped magnetic core 6, transmitting coil 5 and potting compound
4 compositions, attachment base 1 are formed by intermetallic composite coating, and supporting case 2 and support box cover 3 are by nonmetallic composite injection molding, special-shaped magnetic
The die sinking customization of core 6, transmitting coil 5 are formed by coiling fixation；Device assembling process is: first passing through two groups of transmitting coils 5
Tooling is wound on the special-shaped magnetic core 6 processed, is fixed with Instant cement, then will be around making the special-shaped magnetic core 6 of coil by most
Be conducive to receive the received direction of line and be fixed in supporting case 2, injects potting compound 4, it is to be solidified to cover supporting case 2 etc., is cured
Afterwards in whole insertion attachment base 1.
By being designed qualification test to the present embodiment, qualification test includes upper big gun dynamic antivibration dynamic test total 200
Hair, state induction set test 100 times, meet design requirement.
It is above-mentioned experiments have shown that the present invention effectively improves intensity to the passive electromagnetic coupling that sets, ensure that 25 variable-time fuses are passive
The high reliability set.
