Description

Connector and the method for utilizing its assembling illuminator
Technical field
The present invention relates to a kind of connector.In addition, the invention still further relates to a kind of method through this connector assembling illuminator.
Background technology
In back lighting lamp bar, usually a plurality of light emitting modules are electrically connected with being one another in series.Each light emitting module of illuminating lamp bar, the pcb board of for example led module are joined to one another through electric lead, and wherein these electric leads weld together with each pcb board respectively.Yet,, therefore have bigger voltage drop inevitably to another led module from a led module owing between electric lead, there is breakpoint.This voltage drop causes energy loss also and then to power supply to produce higher requirement, to reach the consistent as far as possible purpose of luminous efficiency that makes each lighting module.Simultaneously, also need manually each bar electric lead and pcb board to be welded to connect, this manual operations length consuming time, and can not guarantee the quality of product.
For fear of excessive voltage drop occurring, another kind of solution is also disclosed in the prior art.In this solution, in series be electrically connected through the pcb board of shared electric lead all led modules, each pcb board all is electrically connected to this electric lead through the mode of welding.Owing to used a unique electric lead, on electric lead, there is not breakpoint, therefore keep very little in voltage drop from a led module to another led module.Yet,, and can not guarantee the quality of product equally because same need manually pcb board being welded on the electric lead is therefore consuming time also longer.
Summary of the invention
Therefore, the objective of the invention is to propose a kind of connector.Through using such connector, lighting module can be connected to shared electric lead, and need not cut off electric lead, and this greatly reduces from the voltage drop of lighting module to another lighting module, and has simplified manufacturing process.
The object of the invention is realized through a kind of connector that is used for lighting module; This connector comprises: base plate; Be electrically connected with the pcb board of lighting module; And at least one pair of leg that on base plate, upwards stretches out, first pair of leg design at least one pair of leg is connected with the conduction of electric lead to form for when being pressed into electric lead between the two, cutting the insulating barrier of electric lead.When through connector lighting module being connected to electric lead, connector only cuts the insulating barrier of shared electric lead, and need not to cut off whole electric lead.Thereby shared electric lead just breakpoint can not occur, and this greatly reduces the voltage drop from a lighting module to another lighting module.Simultaneously, only need simply electric lead to be pressed in the connector to form reliable electrical connection.This has simplified installation procedure greatly, has reduced installation difficulty.
According to a preferred design of the present invention, first pair of leg forming microscler slit each other on the direction of upwards stretching out, and forms the V font cut end of opening at the free end of first pair of leg, to cut the insulating barrier of electric lead.When electric lead was pressed to connector, the V glyph shape of this cut end was admitted electric lead more easily, thereby made sharp cut end can more easily cut insulating barrier open.When electric lead was further compressed downwards, the core of electric lead was clamped in the microscler slit, was electrically connected thereby connector is constituted with the core of electric lead.
According to a preferred design of the present invention, the width of microscler slit is progressively widened to the bottom from the upper end, and the width of bottom is less than the width of the core of electric lead.Like this, core just can closely be clamped in the bottom of slit, thereby further guarantees reliable electrical connection.
In a preferred design of the present invention; The mid portion of each leg of second pair of leg at least one pair of leg is close to each other; And its free end away from each other, thereby through mid portion close to each other electric lead is remained under the mid portion.The second pair of leg can prevent reliably that electric lead from deviating from from connector, thereby guarantees that electric lead is electrically connected with the reliable of connector.
According to a preferred design of the present invention, connector according to the present invention has two groups of first pair of legs.These two groups of first pair of legs cut the insulating barrier of electric lead respectively, and contact with core, thereby have further strengthened the reliability that is electrically connected with electric lead.
Propose according to the present invention, be respectively arranged with one group of first pair of leg in the both sides of second pair of leg.Second pair of supporting leg is in the centre of two groups of first pair of supporting legs, thereby just can maintain electric lead well through one group of second pair of supporting leg, prevents that electric lead from deviating from from two groups of second pair of supporting legs.
Preferably, connector is made into integration.This has reduced number of components to a great extent, has reduced manufacturing cost.
Another object of the present invention is to provide a kind of illuminator; This illuminator comprises a plurality of lighting modules and shared electric lead; Each lighting module all is connected to separately, connector recited above; And shared electric lead is connected to each connector, so that each lighting module is connected in series.Therefore there is not breakpoint in shared electric lead in this illuminator, and the voltage drop between wherein each lighting module is less relatively.
Last purpose of the present invention is to provide a kind of assemble method of illuminator, and it may further comprise the steps: a plurality of connectors a) are provided, at least one pair of leg that each connector comprises base plate and upwards stretches out from the base plate; B) base plate of each connector is connected to the pcb board of each lighting module at dorsal part; C) shared electric lead is pressed into respectively in first pair of leg of each said connector, the first pair of leg cuts the insulating barrier of shared electric lead, forms respectively with the conduction of shared electric lead to be connected; D) seal each lighting module.In assemble method according to the present invention, need not to cut off shared electric lead, a lighting module is very little to the voltage drop of another lighting module.Simultaneously, assemble method according to the present invention is more prone to the assembling process of illuminator.
According to a preferred design of the present invention, in step b), weld together through the pcb board of surface-mounted method with connector and lighting module.This has guaranteed the reliability that be electrically connected of connector with pcb board to a great extent, has also simplified production process simultaneously.
Should be appreciated that above generality is described and following detailed description is all enumerated and illustrative, purpose is in order to the present invention who requires to protect further explanation to be provided.
