This application is related to the testing of electronic circuit components, and in particular to a testing device with automatic adjustment function and its test connector.

The testing device is used to test an object to be tested (such as an antenna module, etc.), the object to be tested includes a circuit board and a connector electrically plugged into the circuit board. The testing device mainly tests whether the connector is connected to the circuit on the circuit board.

The existing test device includes a fixture docking plate and a test connector. The fixture docking plate is provided with a hole body, and the test connector is inserted into the corresponding hole body. When testing, the plug pins of the object to be tested are first plugged into the corresponding test connector, and then a connecting line is connected between the test connector and a test device, and then the test can be carried out.

However, the object to be tested (or the test device) may have a tolerance problem. The so-called tolerance problem includes: the protrusion length of the plug-in component from the circuit board is more protruding than the standard protrusion length, and the protrusion length of the test connector from the fixture docking plate is more protruding than the standard protrusion length. Once such problems occur, the plug-in component may be plugged into the corresponding test connector, which may cause a plug-in error or a poor connection. All of these are not conducive to testing and need to be overcome.

Therefore, how to design a device that can improve the above-mentioned shortcomings of the prior art is a major problem that the inventor of the present application is eager to solve.

The purpose of this application is to provide a test device with automatic adjustment function and a test connector thereof.

In order to achieve the above-mentioned purpose, the present application provides a test device with an automatic adjustment function, which is used to test an object to be tested, wherein the object to be tested is provided with at least two plug-in connectors, and the test device comprises: a fixture docking plate, which is provided with at least two docking through holes; and at least two test connectors, each of which is inserted into the docking through holes, and each of which comprises: a connector body, which has a sleeve portion; and a movable sleeve, which can be The jig is provided with a first baffle which is movably sleeved on the sleeve portion; a second baffle which surrounds the movable sleeve and is supported by the jig docking plate; and an elastic element which is sleeved on the movable sleeve and elastically supported between the first baffle and the second baffle; wherein, when each of the connectors is plugged into the corresponding movable sleeve, each of the test connectors elastically expands and contracts relative to the jig docking plate by being plugged into the connectors.

In order to achieve the above-mentioned purpose, the present application also provides a test joint, comprising: a joint body having a sleeve portion; a movable sleeve movably sleeved on the sleeve portion and having a first baffle; a second baffle correspondingly surrounding the movable sleeve; and an elastic element sleeved on the movable sleeve and elastically supported between the first baffle and the second baffle.

Compared with the prior art, the present application has the following effects: when the test connector is subjected to an external force from one direction, it can stretch and contract in the same direction under the elastic support of the elastic element. Therefore, when the connector is plugged into the corresponding movable sleeve, the test connector will automatically stretch and contract in response to the connector and have an automatic adjustment function. At the same time, the elastic element can be used to tightly combine the test connector and the connector to ensure the stability of the test.

The detailed description and technical contents of this application are described below with the help of drawings. However, the attached drawings are only provided for reference and description and are not used to limit this application.

The present application provides a test device with an automatic adjustment function and a test connector thereof. As shown in FIG1 , the test device with an automatic adjustment function (hereinafter referred to as the test device) is used to test an object to be tested (such as an antenna module, etc.) 900. The object to be tested 900 includes a circuit board 91 and at least two connectors 92. Each connector 92 is plugged into the circuit board 91, and the connector 92 has a threaded portion 921. The test is, for example, to test whether the connector 92 is conductive with the circuit on the circuit board 91.

As shown in FIG. 1 , FIG. 2 , FIG. 5 and FIG. 5A , the test device of the present application includes: at least two test connectors 100 and a fixture docking plate 800 , and in detail, also includes a fixture main board 600 .

The fixture main board 600 includes a substrate 6 and a carrier 7, and the carrier 7 is arranged and positioned on the substrate 6. The carrier 7 is used to carry the object to be tested 900. The carrier 7 is provided with at least two connecting parts (without component symbols), and the substrate 6 is provided with at least two main through holes 61. Each connector 92 of the object to be tested 900 extends into each main through hole 61 through each connecting part. Among them, each connecting part corresponds to each main through hole 61.

The fixture docking plate 800 is provided with at least two docking through holes 81, each docking through hole 81 corresponds to each main through hole 61. The docking through hole 81 has a layer portion therein, and this layer portion can be, for example, the narrowest layer portion 811 described later, but the present application is not limited thereto.

It should be noted that the test device of the present application defines a first direction and a second direction which are perpendicular to each other and are not marked with component symbols. Referring to FIG. 1 , FIG. 2 and FIG. 5 , the direction in which the plug connector 92 is plugged into the test connector 100 is a plugging direction (as shown by the dotted arrow in FIG. 5 ), and the first direction is parallel to the plugging direction.

As shown in FIG3 and FIG4 in conjunction with FIG1, each test connector 100 is inserted into each corresponding connecting through hole 81. Each test connector 100 includes: a connector body 1, a movable sleeve 2, a second baffle S and an elastic element 4, and more specifically, includes a threaded member N and a washer L.

The connector body 1 is divided into a sleeve portion 11 and a threaded portion 12. The threaded portion 12 is used to thread the threaded member N, and the washer L is also generally sleeved thereon. The washer L can be a metal washer with a latching effect, and the inner edge of the washer hole has a plurality of latch teeth (without component symbols) as shown in FIG. 4, and the latch teeth can be latched to the threads of the threaded portion 12 as shown in FIG. 5A.

The movable sleeve 2 is movably sleeved on the sleeve portion 11, and the movable sleeve 2 has a first stopper 211 protruding along the second direction. Specifically, the first stopper 211 protrudes along the second direction around a tube opening (without element symbol) of the movable sleeve 2.

The second block S surrounds the movable sleeve 2 and is supported by the fixture docking plate 800, so that the second block S and the first block 211 are spaced apart from each other. The elastic element 4 is also sleeved on the movable sleeve 2, and the elastic element 4 is elastically supported between one side of the second block S and the first block 211.

As shown in FIGS. 1 to 5A , during assembly, the test connector 100 is first inserted into the docking through hole 81 along the aforementioned plugging direction, so that the other side of the second baffle S is supported by the fixture docking plate 800; then, the screw member N is screwed to the threaded portion 12 of the connector body 1 in a direction opposite to the plugging direction together with the aforementioned washer L, so that the washer L and the second baffle S are sandwiched together in the aforementioned step portion (e.g., the narrowest step portion 811), thereby allowing the test connector 100 to be fixed to the fixture docking plate 800.

In the test joint 100, only the joint body 1 and the movable sleeve 2 are tightly fitted together to form an integral component, while the stop ring 3, the elastic element 4, the threaded part N and the washer L are movable parts that can move relative to the integral component (the joint body 1 and the movable sleeve 2).

Thus, as shown in FIG. 5 and FIG. 6, since the test connector 100 can be stretched in the same direction (first direction) relative to the fixture docking plate 800 when subjected to an external force from a first direction, even if the connector 92 of the object to be tested 900 protrudes further from the circuit board 91 than the standard protrusion length due to some factors, the connector 92 protruding further than the standard protrusion length will be elastically supported by the elastic element 4 in the corresponding movable sleeve. During the plugging, one end of the test connector 100 automatically shrinks relative to the fixture docking plate 800 along the first direction (shrinks toward the plugging direction) by abutting and pushing the connector body 1. Correspondingly, the other end of the test connector 100 will protrude relative to the fixture docking plate 800, so that the gasket L originally attached to one side of the aforementioned step portion (e.g., the narrowest step portion 811) is displaced to form a gap G as shown in FIG. 6. In other words, the present application has an automatic adjustment function, and can also tightly combine the test connector 100 with the plug connector 92 through the elastic element 4, thereby ensuring stable testing.

It should be noted that if the test connector 100 does not include the screw-fitting part N, or even does not include the washer L, the elastic element 4 can also be directly or indirectly supported by the fixture docking plate 800, thereby maintaining the state of the test connector 100 inserted into the docking through hole 81, and in such a state, the connector 92 of the object to be tested 900 can still be plugged into the test connector 100, and the test connector 100 plugged by the connector 92 can still have the above-mentioned automatic adjustment function.

For testing, as shown in FIG. 1 and FIG. 6 , the connection wire connectors C1 of at least two connection wires C are respectively screwed onto the threaded portions 12 of at least two test connectors 100 , so that the object under test 900 is connected to a test device (not shown) via each test connector 100 and each connection wire C.

It should be noted that the aforementioned second block S can be any blocking object that can correspond to and surround the movable sleeve 2 and is supported by the fixture docking plate 800, and the present application is not limited thereto. The second block S can be, for example, a blocking ring 3 as shown in FIG. 4 , the blocking ring 3 can be movably sleeved on the movable sleeve 2, and the elastic element 4 is elastically supported between the first block 211 and one side of the blocking ring 3. When the test connector 100 is inserted into the docking through hole 81, the other side of the blocking ring 3 will be blocked by the fixture docking plate 800; or, the second block S can also be provided or The second stopper S is formed on the jig docking plate 800 (not shown in the figure), so the second stopper S can be supported by the jig docking plate 800. When the second stopper S is formed on the jig docking plate 800, the second stopper S is a part of the jig docking plate 800, and the elastic element 4 is elastically supported between the first stopper 211 and a part of the jig docking plate 800. The aforementioned one side and the aforementioned other side of the stopper ring 3 are opposite to each other.

In order to limit the stop ring 3, as shown in FIG. 1, FIG. 3 and FIG. 5A, in one embodiment, a groove 82 may be further provided on the fixture docking plate 800, the groove 82 correspondingly connected to the docking through hole 81 and having a groove bottom surface 821, and the stop ring 3 is accommodated in the groove 82, so that the stop ring 3 is limited by the groove 82. It should be noted that at this time, the other side of the stop ring 3 will be blocked by the groove bottom surface 821.

In order to allow the connector 92 to be pluggably fixed to each other when inserted into the movable sleeve 2, as shown in Figures 2 to 5A, in one embodiment, the movable sleeve 2 may further include an outer tube 21 and an inner tube 23 that are sleeved together. The outer tube 21 has the aforementioned first baffle 211, and the inner tube 23 has a plurality of clamping claws 231 that surround each other, each clamping claw 231 having a clamping protrusion 2311, and the inner tube 23 clamps the threaded portion 921 of the connector 92 with the clamping protrusions 2311 of the plurality of clamping claws 231.

In order to allow the test device of the present application to also have the function of automatic correction, as shown in Figures 1 to 6, in one embodiment, each docking through hole 81 has an inner wall 8111, and each test connector 100 (specifically, its outer cylinder 21) has an outer wall 212, and a gap D is formed between each inner wall 8111 and each outer wall 212 as shown in Figure 5A.

Thus, even if there is an error between the position of any one of the at least two plug-in components 92 of the object to be tested 900 and the standard position, or even if there is an error between the position of any one of the at least two docking holes 81 of the fixture docking plate 800 and the standard position, in such a case where the gap D is added, no matter there is an error in the position of the plug-in component 92 or the position of the docking hole 81, as long as the plug-in component 92 is plugged into the corresponding movable sleeve 2, the test connector 100 can float and deviate relative to the fixture docking plate 800 in the gap D along the aforementioned second direction. In other words, the present application can also have an automatic correction function.

It should be noted that the present application does not limit the method of forming the gap D. The aperture of each connecting through hole 81 may be enlarged by expanding the hole, or the wall thickness of the movable sleeve 2 may be thinned (for example, the wall thickness of the outer tube 21 may be thinned).

In addition, the butt-joint through hole 81 may also be a multi-layer structure with a plurality of layered parts. The apertures of these layered parts are different, including a narrowest layered part 811 with the smallest aperture and the narrowest aperture, and the narrowest layered part 811 has the aforementioned inner wall 8111.

In summary, the test device and test connector with automatic adjustment function in this application can achieve the expected purpose of use and solve the deficiencies of the existing technology. It fully meets the requirements for invention patent application. Therefore, an application is filed in accordance with the Patent Law. Please check and approve the patent of this case in detail to protect the rights of the inventor of this application.

The above is only the preferred feasible embodiment of the present application, and does not limit the patent scope of the present application. All equivalent structural changes made by using the contents of the description and drawings of the present application are also included in the scope of the rights of the present application and are hereby stated.
