Description

The connection set of multilayer buckle

Technical field

The utility model relates to communication network field, particularly a kind of connection set of multilayer buckle.

Background technique

In communication network, can run into the connectivity problem of multilayer buckle usually.With the example that is connected in Micro TCA (Micro Telecom Computing Architecture, the advanced telecommunication computing architecture) standard.

This MicroTCA standard is PICMG (PCI Industrial Computer Manufacturers Group, PCI industrial computer MANUFACTURER tissue) association's up-to-date additional standard on ATCA (Advance Telecom Computing Architecture, advanced telecom counting system structure) standard, setting up and develop.Two kinds of Placements are arranged in the Micro TCA standard.

Mode one, the switching of employing connector, as four tongue connectors, this connector comprises connector male head and the connector female seat that split connects, during connection, with multilayer buckle and connector male head welding, connector male head is inserted in the connector female seat more earlier, so this connector aligning accuracy height, good stability.

Mode two adopts the golden finger direct interconnection, specifically is to adopt the golden finger part on the buckle to be connected with connector on the backboard.When buckle is multilayer, in order to control the relative position between each veneer, need successively adopt negative and positive header stud or screw to position adjacent buckle earlier, partly link to each other by the golden finger on each buckle again with connector on the backboard.

In realizing process of the present utility model, the inventor finds that there is following problem at least in prior art:

Mode one by connector switching, needs earlier the multilayer buckle is connected one by one with the male of connector, because connector need be assembled respectively with buckle, number of pins is many, and pin-pitch is closeer, so it is big to assemble difficulty; In addition, this connector need be sacrificed bigger layout area, can sacrifice about 7% layout area usually, is unfavorable for the product miniaturization; In addition, this connector costs an arm and a leg, and increases device cost, and the cost inferior position is comparatively obvious.

Mode two, adopt the golden finger direct interconnection, require Location accuracy very high, common the moon, a sun screw can't satisfy the aligning accuracy requirement of this Placement, main cause is: because installation base surface changes with each layer buckle, alignment error is in continuous accumulative total, the cumulative error of buckle is 0.32mm, add the moon, the integrating error 0.1mm of sun header stud or screw self, maximum error can reach 0.42mm, and Micro-TCA standard-required golden finger alignment tolerance is no more than ± 0.1mm, does not reach requirement if adopt common negative and positive header stud or screw to connect precision, cause veneer to be inserted easily not entering or the veneer distortion serious.

The model utility content

Connect in order to overcome the available technology adopting connector, the assembling difficulty that exists is big, need to sacrifice bigger layout area and the high problem of cost, and adopt golden finger directly to dock, the big problem of each buckle integrating error that exists, the utility model embodiment provides a kind of connection set of multilayer buckle.Described technological scheme is as follows:

A kind of connection set of multilayer buckle, be used to connect the buckle more than three layers, described connection set comprises concentric ladder post and the fastening piece of being located at ladder post two ends respectively, the progression of described ladder post and the number of plies of described buckle match, wherein, described ladder post is used for supporting and being connected described buckle, and described fastening piece is used for fixing the link position of described ladder post and described buckle.

The beneficial effect of the technological scheme that the utility model embodiment provides is: adopt connector to connect compared to existing technology, the utility model has adopted the multistage ladder columniation structure that matches with the buckle number of plies, has easy assembling, cost is low, needs to sacrifice the advantage of less layout area, adopts golden finger to connect compared to existing technology, employing the utility model connects, because reference level is fixed, therefore can eliminate the integrating error between the buckle, can guarantee the accurate location between each layer buckle.

Embodiment

For making the purpose of this utility model, technological scheme and advantage clearer, the utility model mode of execution is described in further detail below in conjunction with accompanying drawing.

The utility model embodiment is that example is illustrated with the connection set of four layers of buckle, but is not limited to this, and this connection set can connect any buckle more than three layers.

As shown in Figure 1, the connection set of described in the utility model kind of multilayer buckle, be used to connect first layer buckle 10, second layer buckle 11, the 3rd layer of buckle 12 and the 4th layer of buckle 13, described connection set comprises ladder post 20 and the fastening piece of being located at ladder post 20 two ends respectively, the progression of described ladder post 20 and the number of plies of described buckle match, in this example, described ladder post 20 comprises concentric first order post 21, second level post 22, third level post 23 and fourth stage post 24, wherein, first order post 21 in the described ladder post 20 to fourth stage post 24 is respectively applied for support and is connected described first layer buckle 10 to the 4th layer of buckle 13, and described fastening piece is used for fixing the link position of described ladder post 20 and described buckle.Certainly, it will be understood by those skilled in the art that described ladder post 20 can be any ladder post more than three grades, as three, five, six grades of ladder posts or the like, is not limited to the level Four post.

The utility model has adopted the multistage ladder columniation structure that matches with the buckle number of plies, four tongue connectors compared to existing technology, can directly buckle be connected on the ladder post, have easy-to-assemble characteristics, because ladder post itself is simple in structure, can effectively reduce cost because the ladder column volume is little, so only need sacrifice less layout area can realize connection.

The utility model has adopted the multistage ladder columniation structure that matches with the buckle number of plies, golden finger compared to existing technology connects, because connecting reference level, the utility model is fixed on the 4th layer of buckle, therefore can eliminate the integrating error between four layers of buckle of first layer to the, and can guarantee accurate location between each layer buckle, fundamentally solved the high problem of positioning accuracy request in the golden finger direct interconnection, for directly golden finger and backplane interconnect provide a kind of effective cheaply solution.

In addition, adopt the utility model to connect, different buckles can be beaten different holes, can prevent erection sequence mistake between the buckle, adopt the ladder post to connect the difference that to control between the different buckles flexibly simultaneously and join high request, have the use flexible characteristic.
