## Title
Test fixture for testing positioning of connector

## Abstract

A test fixture for testing positioning of a connector includes a support, a housing mounted on the support, a movable block received within in the housing, a power module set inside of the movable block, a conductive block mounted on the power module, a probe element aligned with the conductive block, and a light-emitting element electrically connected to the power module and the probe element. The movable block is movably mounted on the support, and includes an extending portion. When the connector is precisely positioned in a slot of an electronic device and the extending portion is inserted into the slot of the electronic device, the movable block is resisted by the connector to be driven to move such that the conductive block contacts the probe element, thereby turning on the light-emitting element.

## Background
BACKGROUND
1. Technical Field
The present disclosure relates to test fixtures and, particularly, to a test fixture for testing whether a connector is precisely positioned in an electronic device.
2. Description of Related Art
Connectors are often manually positioned in a receiving space of an electronic device. However, it is relatively difficult to determine whether the connector is precisely positioned in the receiving space of the electronic device.
Therefore, what is needed is a test fixture for determining whether a connector is precisely positioned to overcome the described limitations.

DETAILED DESCRIPTION
Referring to FIGS. 1-3, an embodiment of a test fixture 1 is illustrated. The test fixture 1 is used to be inserted into a slot 21 of a sidewall of an electronic device 2 to test whether a connector 3 is precisely positioned in the slot 21 of the electronic device 2. The test fixture 1 includes a support 10, a housing 20 mounted on the support 10, a movable block 30 movably placed on the support 10 and within the housing 20, a power module 40 within the movable block 30, and a conductive block 50 mounted on the power module 40.
The test fixture 1 further includes a probe element 60 aligned with the conductive block 50, and a light-emitting element 70 electrically connected to the power module 40 and the probe element 60.
To test whether the connector 3 is precisely positioned in the electronic device 2, the movable block 30 is inserted into the slot 21 by an external force. When the connector 3 is precisely positioned in the electronic device 2, the movable block 30 is resisted by the connector 3 to move until the conductive block 50 contacts the probe element 60, thereby closing a circuit 100 (as shown in FIG. 5) of the light-emitting element 70, and turning on the light-emitting element 70 to indicate that the connector 3 is precisely positioned in the electronic device 2. In order to better understand the disclosure, an exemplary embodiment is described in detail.
The movable block 30 includes an extending portion 31 extending from one side thereof. The extending portion 31 can be driven by the movable block 30 to be inserted into the slot 21.
The probe element 60 includes a conductive probe 61 and an adjusting portion 62. The adjusting portion 62 is configured for adjusting a distance between the conductive probe 61 and the conductive block 50. One end of the light-emitting element 70 is electrically connected to the power module 40, and the opposite end is electrically connected to the conductive probe 61.
The test fixture 1 further includes a limiting post 80 and an elastic element 90. The limiting post 80 is set inside of the movable block 30. One end of the elastic element 90 is connected to the limiting post 80, and the opposite end is connected to a sidewall of the housing 20 away from the extended portion 31. During testing when the extending portion 31 is inserted into the slot 21, the movable block 30 can be moved by the connector 3, if the connector 3 is precisely positioned, and the elastic element 90 will be deformed by the limiting post 80. When the extending portion 31 is removed from the slot 21, the elastic element 90 will rebound to drive the movable block 30 to return to an original position. In one embodiment, the elastic element 90 is a spring.
Referring to FIGS. 4-5, to test whether the connector 3 is precisely positioned, the extending portion 31 is inserted into the slot 21. If the connector 3 is precisely positioned in the electronic device 2, the extending portion 31 will be moved by the connector 3, thereby moving the movable block 30, the power module 40, and the limiting post 80 to deform the elastic element 90. The conductive block 50 is driven by the movable block 30 to move towards the conductive probe 61 until it contacts the conductive probe 61. When the conductive block 30 contacts the conductive probe 61, the circuit 100 is closed turning on the light-emitting element 70 to indicate that the connector 3 is precisely positioned. Otherwise, if the light-emitting element 70 does not turn on, the connector 3 is determined as not precisely positioned.
After the test fixture 1 tests that the connector 3 is precisely positioned in the electronic device 2, the extending portion 31 is removed from the slot 21 of the electronic device 2. After the extending portion 31 is removed from the slot 21, the elastic element 90 rebounds to drive the movable block 30 to return to the original position.
Although the present disclosure has been specifically described on the basis of the exemplary embodiment thereof, the disclosure is not to be construed as being limited thereto. Various changes or modifications may be made to the embodiment without departing from the scope and spirit of the disclosure.
