Abstract
The utility model discloses a DIN type two ins and two outs electric bridge, including cavity and joint, connect and adopt the mode of sticising with being connected of cavity. The utility model discloses beneficial effect lies in, connects and adopts the mode of sticising with being connected of cavity, connects protection level and reaches IP68, the band wire that is equipped with the insulator avoids the debugging in placing the locating hole, adopt inside and outside apron mode, the cavity inner chamber has the fastening that contacts of step face and interior apron, and outer apron only plays waterproof seal and pleasing to the eye effect. Consequently, protection level is high, and the intermodulation is good, avoids the debugging.
Description
Technical field
This utility model relates to a kind of DINd type two and enters two and go out electric bridge, reaches IP68 particularly to electric bridge degree of protection, exempts from debugging, belong to technical field of communication equipment.
Background technology
At present, the cavity Stripline hybrid that prior art uses. Degree of protection low (generally can reach IP65, it is desirable to up to IP67 time higher), third order intermodulation poor (generally can reach at most-150dBc), debugging difficulty is big, cost is high.
Summary of the invention
The purpose of this utility model is that and overcomes disadvantages mentioned above, and a kind of DINd type two of design is entered two and gone out electric bridge.
In order to realize foregoing invention purpose, this utility model adopts the following technical scheme that
A kind of DINd type two is entered two and is gone out electric bridge, and including cavity and joint, described joint is connected by, with cavity, the mode of pressing.
Preferably, in described cavity, it is provided with hole, location, in hole, described location, places the band wire equipped with insulant.
Preferably, described insulant is insulator or insulation strip.
Preferably, being provided with inner cover plate in described cavity, described cavity is outside equipped with outer cover plate, and described inner cover plate fixes with the step surface being arranged in cavity, and described outer cover plate is fixed by screw.
This utility model has the beneficial effects that, joint is connected by, with cavity, the mode of pressing, and protection of welded joints grade reaches IP68; Band wire equipped with insulator is placed in hole, location, avoids debugging; Adopt inside and outside cover board mode; Cavity inner chamber has step surface to contact with inner cover plate fastening, and outer cover plate only plays sealing waterproof and effect attractive in appearance. Therefore degree of protection is high, and intermodulation is good, avoids debugging.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, joint 2 is pressed onto in cavity 3, with screw 6, joint 2 is fastened, insulation strip or insulator 4 are put in position corresponding in cavity 3, two band wire 5 and insulation strip 4 are sequentially placed in cavity 3 by frock and weld, clean inner cavity, inner cover plate 7 and cavity 3 screw 6 are fastened, put into sealing ring 8, finally outer cover plate 1 and cavity 3 are fastened.
This utility model is connected in base station, repeater and indoor distributed system, owing to joint 2 is pressed onto in cavity 3, use inner cover plate 7 individually contact with cavity 3 and fasten simultaneously, therefore well improve intermodulation, and very stable, band wire 5 sheet metal is made, therefore Insertion Loss is little, load power is big, fasten with cavity 3 with sealing ring 8 and outer cover plate 1, it is ensured that sealing and attractive in appearance.
The left side in figure is after taking inner cover plate 7 and outer cover plate 1 away, it is shown that cavity 3, band wire 5, insulator and insulation strip 4, joint 2 assembling and connection status mutually, the right is the situation covering inner cover plate and outer cover plate.
