Abstract

The utility model discloses a deconcentrator which includes a bus, a connecting block, and a plurality of sublines. The sublines are provided with detachable joints. The deconcentrator of the utility model is simple in structure, and the detachable joints are adopted on the sublines. When an electric device connected with the sublines needs to be replaced, one end of the deconcentrator can be dismantled with the electric device together for replacement, so the dismantlement is very convenient, and the dismantlement avoids the entire replacement of the deconcentrator, so the assembly cost is low.

Description

A kind of deconcentrator

Technical field

The utility model belongs to the power wiring equipment technical field, specifically relates to a kind of deconcentrator.

Background technology

At present in the power wiring process, people install deconcentrator usually and come from backbone (bus) to tell some service mains (sub-line) in wire casing.Sub-line directly is connected with the electricity consumption device, in case be generally trouble of non-dismountable mechanism or dismounting after the installation between sub-line and the electricity consumption device.There are a lot of drawbacks in the deconcentrator of said structure: one, when the electric device damage of a certain sub-line connection needs to change, generally need change deconcentrator simultaneously, and increased whole electric device use cost; Its two, the quantity of the electric device that require to need connects during installation is consistent with the quantity of the interior sub-line of deconcentrator, the quantity of the electric device of Lian Jieing then needs to change deconcentrator less than the quantity of sub-line if desired, has reduced efficiency of assembling; If directly adopt this deconcentrator, then remaining sub-line is generally put in disorder and is caused security incident easily.

Summary of the invention

The utility model provides a kind of deconcentrator, and this deconcentrator is simple in structure, and sub-line is provided with separable joint, has guaranteed the electric device convenient disassembly that is connected with sub-line, and has avoided the replacing of deconcentrator, and assembly cost is low.

A kind of deconcentrator comprises bus, contiguous block and plurality of sub line, and described sub-line is provided with separable joint.

Described joint comprises the male end and female end that cooperatively interacts; Described female end outer wall is provided with screw thread, and described male end is with the adapter sleeve that is connected with the female end outer wall thread outward; Described male end outer wall is provided with the snap ring of spacing adapter sleeve.The setting of adapter sleeve, being threaded of male end and female end of having realized joint guaranteed dismounting between the male end and female end and the convenience of installing.

Described male end is to be provided with two contact pins in hollow and the inner chamber; Described female end is provided with the cannelure that cooperates with male end, and described female end is provided with the jack that cooperates with contact pin.The male end outer wall is inserted in the cannelure of female end in the use, and the contact pin in the male end is inserted in the jack of female end simultaneously, guarantees the connection of circuit.

For ease of more accurately the outer wall of male end being inserted in the female end cannelure, can a guide pad that axially is provided be set at described male end inner chamber side face; The ring side face is provided with a gathering sill that cooperates with guide pad in described cannelure simultaneously.The quantity of guide pad and gathering sill setting also can be provided with a plurality of as required.

Deconcentrator of the present utility model is simple in structure, adopts separable joint on the sub-line, when needs are changed with sub-line is connected electric device, only an end need be disassembled with the electric device integral replacing and get final product, dismantle very conveniently, and avoided the integral replacing of deconcentrator, assembly cost is low.

Embodiment

Shown in Fig. 1～3, a kind of deconcentrator comprises bus 1, contiguous block 2 and six strip lines 3, and sub-line 3 is provided with separable joint 4.Joint 4 comprises male end 5 and the female end 6 that cooperatively interacts, and both are by being threaded.But also can select the joint of other decomposition textures between male end 5 and the female end 6 according to actual needs for use, for example can select the joint that connects by snap fastener etc.

The dismounting arrow logo that female end 6 outer walls are provided with screw thread and are used to illustrate; Be provided with cannelure 10 in the female end 6, the cylinder 14 at female end 6 centers is provided with two jacks 11 near in the end of male end 5, and cylinder 14 outer peripheral faces are that cannelure 10 inner peripheral surfaces are provided with gathering sill 13.

Be with the adapter sleeve 7 that is connected with female end 6 outer wall threads outside the male end 5, be provided with screw thread in the adapter sleeve 7; Male end 5 outer walls be provided with restriction adapter sleeve 7 screw-in depths snap ring 8; The thickness of male end 5 outer walls equates with the width of cannelure 10 in the female end 6, is convenient to male end 5 outer walls are inserted in female end 6 cannelures 10; The equal and opposite in direction of the cylinder 14 in the size of male end 5 inner chambers and the female end 6 is provided with 9, two contact pins 9 of two contact pins and matches with female end 6 internal plug seats 11 sizes in the inner chamber; Male end 5 inner chamber side faces are provided with the guide pad 12 of axial setting, and guide pad 12 matches with gathering sill 13 on the female end, and being provided for of gathering sill 13 and guide pad 12 controlled male end 5 outer walls and be inserted into accurately in female end 6 cannelures, is convenient to both quick assemblings.

The actual installation unloading process of the deconcentrator in the present embodiment is: during installation, at first the outer wall of male end 5 is inserted in the cannelure in the female end 6, guarantee that simultaneously guide pad 12 is inserted in the gathering sill 13 and contact pin 9 is inserted in the jack 11, when male end 5 insert put in place after, adapter sleeve 7 and female end 6 outer walls are screwed can finish being connected between male end 5 and the female end 6; During dismounting, only need be outwarded winding adapter sleeve 7, male end 5 are extracted to get final product then.
