Description
Technical field
the utility model relates to domain of communication equipment, particularly relates to a kind of circulator of center conductor outer lead band gap structure.
Background technology
circulator is widely used in GSM; CDMA; TD-SCDMA(3G); etc. TD-LTE(4G) in the base station and mobile station system of wireless communication field; in the remote card reader/writer of RFID; mainly transmitting and receiving the input of system rate of doing work amplifier etc., the isolation of output, and protection power amplifier is not reflected the effect that signal disturbs and the effect of serving as duplexer.
as shown in Figure 1, 2, circulator comprises housing 1, is successively set on from bottom to up permanent magnet 2, magnetic conduction sheet 3, ferrite (band dielectric ring) 4, center conductor 5, ferrite (band dielectric ring) 4, magnetic conduction sheet 3 ', permanent magnet 2, cover plate 6 in housing 1.Permanent magnet 2 provides bias magnetic field for ferrite 4, and center conductor 5 has three exits, is respectively port
, port
and port
, draw from three notches of housing 1.Circulator can be realized the one-way circulation circulation of microwave power, reverse isolate.One-way circulation path is
→
→
→
if signal power is from port
input,
there are two ports that face mutually
with
, but signal all flows to port
, and to port
without shunting; If signal from
port input, arrives port
output, port
without shunting, the like, its equivalent electric circuit is as shown in Figure 3.
each exit has lead-in wire, this lead-in wire need to bend, formation is the wing shape of gull, at present, go between all linearly, in the time carrying out bending, easily cause clubfoot position inaccurate, curved shape is wayward, there is the problems such as bending lead format is irregular, and inflection point is inconsistent, thereby cause the problems such as the profile consistency of circulator is poor and indicator consilience is poor.
Summary of the invention
the purpose of this utility model is to provide a kind of circulator of center conductor outer lead band gap structure.
for achieving the above object, the technical solution adopted in the utility model is:
a kind of circulator of center conductor outer lead band gap structure, it comprise have inner chamber housing, be arranged on permanent magnet, ferrite, magnetic conduction sheet and center conductor in described inner chamber, described center conductor has 3 exits that lead to outside described housing, 3 described exits have respectively lead-in wire, and the lead-in wire outside described housing offers at least one group of breach in its Width both sides.
preferably, described breach offers two groups, and the breach described in every group is symmetricly set on described lead-in wire both sides.
further preferably, described lead-in wire carries out respectively bending at two groups of described gap positions, and after bending, to be gull wing for described lead-in wire.
preferably, described magnetic conduction sheet, permanent magnet and ferrite is respectively arranged with 2, and described permanent magnet, magnetic conduction sheet, ferrite, center conductor, ferrite, magnetic conduction sheet, permanent magnet is successively set in described inner chamber from bottom to up.
preferably, described circulator also comprises cover plate, and the oral area of described housing is provided with on the outer peripheral face of internal thread, described cover plate and is provided with external screw thread, and both are threaded connection.
preferably, on described ferrite with dielectric ring.
because technique scheme is used, the utility model compared with prior art has following advantages:
the utility model has solved the bending position disunity that original center conductor outer lead exists in the time of bending, the problems such as curved shape is inconsistent, by being set, breach provides bending position, thereby improve operating efficiency, lead-in wire bending becomes easier, thereby improve the profile consistency of device and the consistency of index, client has been used more convenient.

Embodiment
below in conjunction with drawings and Examples, the utility model is further described:
a kind of circulator as shown in Figure 1, it comprises 3,3 ', 24,1 center conductors 5 of ferrite with dielectric ring of 2,2 magnetic conduction sheets of 1,2 permanent magnet of housing with inner chamber 10.Wherein: permanent magnet 2, magnetic conduction sheet 3,3 ', ferrite 4 and center conductor 5 are arranged in inner chamber 10, it arranges order and is: permanent magnet 2, magnetic conduction sheet 3, ferrite 4, center conductor 5, ferrite 4, magnetic conduction sheet 3 ' (on magnetic conduction sheet 3 ', be provided with little ear using as install location with), permanent magnet 2 sets gradually from bottom to up.
as shown in Figure 4: center conductor 5 has three exits that lead to outside housing 1, three exits have respectively lead-in wire 50, lead-in wire 50 outside housing 1 offers at least one group of breach 500 in its Width both sides, in the present embodiment, breach 500 offers two groups, and every group of breach 500 is symmetricly set on lead-in wire 50 both sides.In use, lead-in wire 50 is carried out respectively to bending two groups of breach 500 positions, after bending, going between 50, to be gull wing.Center conductor 5 all provides in advance to shape and the position of 50 bendings that go between, so just can calculate the lead-in wire 50 of circulator at the initial bending position of the part of housing 1 outside and bending position below, in the time of the conductor 5 of design centre, adopt the mode of symmetric windows 500 to provide bending position at corresponding bending point, so not only bending point position is fixing unified, and because this bending position exists symmetric windows 500, and make bending operation become very easy, both saved the time, improve efficiency, also improved the profile of device and the consistency of index.
