Description

本发明的实施例涉及一种电器件测试夹具。
背景技术
随着技术的发展，电器件的应用也越来越广泛，以发光二极管(Light Emitting Diode，LED)电器件为例，其具有体积小、亮度高、热量及耗电量低等优点，已经被广泛应用于指示灯、信号灯、仪表显示、手机背光源等场合。
为了保证LED的正常使用，通常需要使用测试设备对LED进行发光强度等的测试，因此通常需要预先通过LED测试夹具进行LED固定之后，再进行LED测试。即将固定有LED的测试夹具放置固定在测试设备上。随着LED的广泛应用，LED产品的规格和型号不断增加，通常对应不同规格、型号的LED，设置有相对应的多个测试夹具。即一种型号的LED对应一种款式的专用测试夹具，从而方便对不同规格的LED进行测试。
然而，LED通常为批量生产，则对应不同型号的LED需要有多个不同的测试夹具，成本较高。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例的附图，对本发明实施例的技术方案进行清楚、完整地描述。显然，所描述的实施例是本发明的一部分实施例，而不是全部的实施例。基于所描述的本发明的实施例，本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实施例，都属于本发明保护的范围。
下面结合附图对本发明实施例电器件测试夹具进行详细描述。
本发明实施例提供一种电器件测试夹具，如图1和图2所示，包括固定底座11，电极固定架12，阴、阳两个电极13，挡块支架14，以及挡块15。
固定底座11中设有贯通的两个导线安装孔112，两个安装孔中均穿设有导线20；因导线安装孔设置在固定底座11中，侧视时看不到，故而图中用虚线表示。
电极固定架12固定在固定底座11上，且电极固定架12上设有两个独立的长孔槽21。
两个电极13分别固定在电极固定架12的两个长孔槽21中，且能够分别在对应的长孔槽21中运动；两个电极13分别与对应的导线20电连接，两个电极13之间用于连接电器件1。
挡块支架14，挡块支架14固定在固定底座11上。
挡块15，挡块15与挡块支架14之间设有复位弹簧16；挡块15用于固定电器件1。
本发明实施例提供的电器件测试夹具中，在穿设有导线的固定底座上设有电极固定架，电极固定架的长孔槽中分别固定有与导线连接的阴、阳电极，且电极能够在长孔槽中运动。两个电极之间连接电器件，并通过设在挡块支架上的挡块完成固定。由此可知，以电器件为LED为例，当需要对LED进行测试时，首先通过拨动挡块压缩复位弹簧，使挡块远离电极，方便LED与电极连接。待LED的正、负极与阴、阳电极对应连接之后，松开挡块使其在复位弹簧的作用下复位，以完成LED的固定，方便后续检测。该过程中，LED连接在两个电极之间，每个电极能够在各自的长孔槽中运动，从而能够根据需要改变两个电极之间的间距大小，从而对应连接不同规格、型号的LED。该电器件测试夹具通用性强，可降低测试成本。而且，通常，新型的LED首先研发出来，但是对应新型LED的测试夹具需要后续研发，导致无法及时进行LED的测试，无法正常使用。而本发明实施例提供的电器件测试夹具通过电极之间间距可调，能够很好地适用于不同规格的LED，能够及时完成新型LED的检测，方便使用。
需要说明的是，本发明实施例中的电器件测试夹具通常多用于检测LED，当然也可以用于检测其他电器件，本发明的实施例以检测LED为例来说明。
为了便于说明，将电极13设定为包括阴极132和阳极131。
由上述夹装过程可知，LED需要连接在两个电极之间，即LED的正极 与阳极131连接、LED的负极与阴极132连接，阳极131和阴极132分别连接有一根导线20，从而便于向LED供电。
为了提高LED与电极13连接的稳定性，可以通过控制挡块15对LED的压力大小来实现，也可以如图1和图3所示。图3中所示电极13可以为阴极132，也可以为阳极131。在阴、阳两个电极(132，131)相对一侧上远离固定底座11和电极固定架12的顶端，即图1和图3中两个电极13相邻的顶角处设有凹陷31。该凹陷31的结构为矩形，从而两个凹陷31共同构成矩形框，符合LED的结构。当然，也可以根据LED的结构对凹陷的结构进行改进。例如，凹陷31内设有探针32，探针32分别连接LED的正、负极，从而通过探针的设置，能够提高电极13与LED引脚连接的可靠性，使接触良好。这其中，当将LED与探针32连接时，使LED置于凹陷31中，需要保证在电极13与挡块15相对的一侧LED与电极13前端面相对齐或超出，因为每个电极13上的凹陷31的深度需要保证挡块15顺利对LED进行抵压操作。
在实际应用时，需要将本发明实施例提供的安装有LED的测试夹具放置在测试设备上进行LED测试，而本发明实施例提供的测试夹具能够应用到不同规格、型号的LED中。因此为了提高测试夹具的使用重复性，如图1和图2所示，可以在固定底座11上设置相应的刻画线111(可以为作用相同的凹槽等)。例如，固定底座11可以为圆柱体，上述刻画线111例如设在圆柱体的侧壁上。而且，刻画线111可以包括有多条，图2中固定底座11的侧壁上设有4条刻画线，且4条刻画线等距、均匀排列。且在操作时，可以将相对的两条刻画线111的连线正交设置，以便于统一操作。
例如，导线安装孔位于固定底座11的中心区域，保证其与电极所设位置相对应，且可以为长圆孔或长方形孔，从而便于导线20的调整。结合图1和图3可知，每个电极13上沿垂直于固定底座11的方向设有上下贯通的一个通孔33，从而穿设过安装孔的导线20能够穿设固定在通孔33中，完成电极13与导线20的电连接。
结合图4和图5所示，电极固定架12例如为长方体结构，且可以通过螺纹连接、销钉连接等方式与固定底座11固定连接，此时电极固定架12上例如设有螺纹安装孔50等。在电极固定架12上，对称设置有两个独立的长孔 槽21，从而便于将电极固定在长孔槽21中并在其内滑动。可以如图2所示，在每个电极13上沿垂直于电极固定架12的方向设有前后贯通的螺栓孔22，螺栓孔22中设置螺栓，并通过相应的螺母将电极固定在长孔槽21中，从而通过拧动螺母即可完成电极13的位置调节及固定。即当需要调节电极13位置时，拧动螺母，实现电极13位置调整。当电极13调整到位后，通过拧紧螺母，完成电极13的固定。
为了保证整体安装的整齐性，可以将设置螺母侧的长孔槽21设置为沉孔结构。即具有容纳螺母的空间，同时也起到一定的限位作用。
另外，如图1所示，两个电极13相邻较近，因此在调整位置时，易发生两个电极13碰触等误操作，造成短路等。因此如图1、图4和图5所示，可以在电极固定架12上设置凸块121，凸块121位于两个长孔槽21之间，从而能够有效隔离两个电极13，保证安全性。而且，在进行装配时，该凸块121还能够起到辅助支撑的作用。同时由于凸块121的位置、结构固定，在进行电极13调整、固定以及后续LED的连接时，还能够起到定位的作用，便于装配。
在电极13位置调整的过程中，两个电极13之间后续需要安装LED，因此可将两个电极13同步调整，从而使连接其上的LED居中设置，方便固定。
当然，电极13与电极固定架12的连接也可以为其他方式。例如通过螺旋连接杆将两者进行连接等，以能实现两个电极13之间间距可调即可。
当两个电极13的探针32上连接有LED之后，需要通过挡块15进行固定，避免LED的松动。例如，可以通过挡块15对LED的抵压完成固定，通过控制挡块15对LED的压力，能够保证LED固定的同时，挡块15不会对LED产生挤压损坏等。在图1中，挡块15与挡块支架14固定连接，从而通过在挡块15与挡块支架14之间设置复位弹簧16，完成挡块15对LED的抵压操作。即挡块15在初始位置时(图1中挡块所在位置)，复位弹簧16处于压缩状态。
例如，参考图6至图9，挡块支架14为U型结构，挡块15位于U型结构内，且挡块支架14可以通过螺纹连接等方式固定在固定底座11上。此时挡块支架14上设有螺纹孔60。从而U型结构的挡块支架14形成有容纳挡块15的空间，方便挡块15往复运动。挡块支架14的底端设置有滑槽71，对应 的在挡块15的两侧设有凸起滑块81。从而通过滑块81与滑槽71的配合，保证挡块15往复运动的平稳性。这其中，为了进一步提高挡块15运动的稳定性及安装便捷性，如图1所示，在挡块15远离电极13的后端面设置有至少一个圆柱形导向柱151，例如对称设置两个，对应的在挡块支架14上设置有导向孔72，将导向柱151穿设过导向孔72，且两者轴承连接。即导向孔72处设有轴承，从而使挡块15沿导向柱151延伸方向往复运动。当然，在保证挡块15运动的稳定性的前提下，也可以仅仅通过设置导向柱151来实现。
例如，结合图1可知，复位弹簧16可设在两个导向柱151之间，复位弹簧16的一端与挡块15后端面固定连接、另一端与挡块支架14固定连接。在应用时，首先拨动挡块15，使挡块15与电极13分离，并压缩复位弹簧16。然后将LED连接在两个电极13的探针32上。待LED连接完成之后，松开挡块15，在复位弹簧的作用下复位，从而挡块15能够顺利抵压LED，完成LED在电极13上的固定。即完成LED的夹装。方便后续LED测试。
当然，为了方便将LED与电极13连接，可以在固定底座11上设置卡接孔118，如图1和图2所示，图2中因卡接孔118置于固定底座11中，侧视时看不到，故而用虚线表示。图10示出了测试夹具安装电器件的示意图。当拨动挡块15远离电极13运动至适当位置后，通过在卡接孔中插入卡接块152等完成挡块15的卡接固定。当LED连接后，取走卡接块，取消对挡块15的卡固，使挡块15顺利完成对LED的抵压固定。卡接孔118的个数例如为至少一个。每个卡接孔118配置一个卡接块152。在图1和图2中，以设置了两个卡接孔为例进行说明。
由上述过程可知，在LED连接、测试等过程中，需要拨动挡块15。因此，如图8所示，在挡块15远离固定底座11的一侧可以设置横向U型槽82，即在挡块15顶端可以设置横向U型槽82。从而操作人员可以通过U型槽82来拨动挡块15，方便挡块15开合。当然，也可以在挡块15的顶端加装把手等结构件。
同样，为了方便操作人员将LED连接在电极13上或从电极13上取下LED，可以通过在挡块15与电极13相对的前端面对应探针32的区域设置竖向开口槽83，其中该开口槽83的宽度不宜过大，避免影响挡块15对LED的固定作用。结合图1可知，开口槽83可以对应上述凸块121设置。
在图9中，挡块15与电极13相对的前端面还可设有刻度线91(图中未示出刻度值)。刻度线91的设置位置有多种选择，例如设在挡块15前端面上部或下部区域，也可以设在挡块15顶端区域。本实施例中，为了便于与电极13直观对应，方便比对和观察，可以将刻度线91设在挡块15前端面上部区域，且设在开口槽83的两侧。图9中的刻度线91设有两条，在开口槽83两侧对称设置。通过设置刻度线91，便于电极13位置调整时进行比对，保证LED居中设置，提高检测效率。
