[0030] The following will disclose multiple embodiments of the present invention with drawings. For the purpose of clear description, many practical details will be described together in the following description. However, it should be understood that these practical details should not be used to limit the present invention. In other words, in some embodiments of the present invention, these practical details are not necessary. In addition, in order to simplify the drawings, some conventional structures and components will be depicted in a simple schematic manner in the drawings.

[0031] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0032] In addition, in the present utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes, and do not specifically refer to the order or sequence, nor are they used to limit the present utility model. They are only used to distinguish components or operations described with the same technical terms, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0033] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings:

[0034] First, as Figure 1 and Figure 2 As shown, the utility model provides a test fixture 1, including a base 11, a substrate 12, a plurality of pins 13 and a carrier 14. The substrate 12 is arranged on the base 11, and the first circuit and the second circuit are printed on two opposite sides of the substrate 12 respectively, and the first circuit is electrically connected to the second circuit. One end of the substrate 12 is exposed from the base 11, and a contact 121 is provided on one side of one end of the substrate 12, and the contact 121 is electrically connected to the first circuit or the second circuit. A plurality of pins 13 are arranged on the substrate 12 in sequence, and the plurality of pins 13 are electrically connected to the first circuit or the second circuit. The carrier 14 is arranged on the substrate 12 in a liftable manner, and the carrier 14 corresponds to the plurality of pins 13. When the carrier 14 descends, the plurality of pins 13 penetrate the carrier 14.

[0035] Through the above technical solution, when testing the circuit board, it is sufficient to push the base 11 to drive one end of the substrate 12 to be inserted into the predetermined position of the FCT test equipment. The FCT test equipment can fix the substrate 12 and electrically connect it to the FCT test equipment through the contact 121. No manual wiring is required, which saves wiring time, improves test efficiency, and avoids the situation where errors are prone to occur in manual wiring.

[0036] In some preferred embodiments, the substrate 12 is provided with a guide opening 122, which is located at one end of the substrate 12. In specific applications, a guide column is provided on the FCT test device, and when the base 11 is pushed to drive one end of the substrate 12 to be inserted into a predetermined position of the FCT test device, the guide column cooperates with the guide opening 122 to guide the substrate 12, so that one end of the substrate 12 can be accurately inserted into the predetermined position of the FCT test device.

[0037] Specifically, the width of the guide opening 122 gradually decreases from the end away from the base 11 to the end close to the base 11. This design can ensure that when the base 11 is pushed to drive one end of the substrate 12 to be inserted into a predetermined position of the FCT testing equipment, the guide opening 122 accurately corresponds to the guide column.

[0038] In this embodiment, the number of guide openings 122 is designed to be three, and the three guide openings 122 are arranged in a straight line. It is understandable that the number of guide openings 122 can also be adaptively increased or decreased according to actual needs. The above is only one embodiment of the utility model and should not be limited thereto.

[0039] like Figure 3 and Figure 4 As shown, in some preferred embodiments, the substrate 12 is provided with a socket 123, and the carrier 14 is provided with a lifting rod 141. When the carrier 14 is set on the substrate 12, one end of the lifting rod 141 is clamped in the socket 123. In specific applications, the socket 123 on the substrate 12 cooperates with the lifting rod 141 on the carrier 14, so that the carrier 14 can move downward along the axial direction of the lifting rod 141 when subjected to external force (that is, the carrier 14 descends, so that the plurality of pins 13 penetrate the carrier 14) and can move upward along the axial direction of the lifting rod 141 when not subjected to external force (that is, the carrier 14 rises, and the plurality of pins 13 are restored to the state where they do not penetrate the carrier 14).

[0040] In some preferred embodiments, the substrate 12 is provided with a guide hole 124, and the carrier 14 is provided with a guide rod 142. When the carrier 14 is disposed on the substrate 12, one end of the guide rod 142 passes through the guide hole 124. In specific applications, the guide hole 124 cooperates with the guide rod 142 to guide the carrier 14, thereby improving the moving accuracy of the carrier 14, so as to ensure that the circuit board to be tested placed on the carrier 14 is accurately electrically connected to the plurality of pins 13.

[0041] In some preferred embodiments, a guide sleeve 15 is provided in the guide hole 124, and when the carrier 14 is disposed on the base plate 12, one end of the guide rod 142 passes through the guide sleeve 15. By providing the guide sleeve 15 in the guide hole 124, the movement accuracy of the carrier 14 can be further improved to ensure that the circuit board to be tested placed on the carrier 14 is accurately electrically connected to the plurality of pins 13.

[0042] In some preferred embodiments, the left and right side walls of the base 11 are provided with outwardly protruding guide bars 111. In specific applications, the FCT test equipment is provided with a guide groove that matches the shape of the guide bar 111. When the base 11 is pushed to drive one end of the substrate 12 to be inserted into the predetermined position of the FCT test equipment, the guide groove cooperates with the guide bar 111 to guide the base 11, so as to ensure that one end of the substrate 12 is accurately inserted into the predetermined position of the FCT test equipment.

[0043] Specifically, a hand-holding position 112 is provided on the left and right side walls of the base 11 , and the hand-holding position 112 is convenient for workers to take and place the test tool 1 .

[0044] In a second aspect, the utility model provides an FCT testing device, comprising the testing tool 1 of the first aspect.

[0045] like Figure 5 and Figure 6 As shown, in some preferred embodiments, the above-mentioned FCT testing equipment also includes a test frame 2, a fixing mechanism 3 and a pressing mechanism 4; the test fixture 1 is slidably set on the test frame 2; the fixing mechanism 3 is set on the test frame 2 and is located on the sliding path of the test fixture 1, and the fixing mechanism 3 is used to fix the substrate 12 after the test fixture 1 slides to the predetermined position of the test frame 2; the pressing mechanism 4 is located above the test frame 2 and corresponds to the test fixture 1, and the pressing mechanism 4 is used to press down after the test fixture 1 slides to the predetermined position of the test frame 2, so that a number of pins 13 pass through the carrier 14 and are electrically connected to the circuit board to be tested placed on the carrier 14.

[0046] In a specific application, first, the base 11 is pushed to drive one end of the substrate 12 to be inserted into a predetermined position of the FCT test equipment; secondly, the fixing mechanism 3 fixes the substrate 12; thirdly, the circuit board to be tested is placed at a predetermined position on the carrier 14; finally, the pressing mechanism 4 presses down to push the circuit board to be tested and the carrier 14 to move downward, so that a number of pins 13 penetrate the carrier 14 and are electrically connected to the circuit board to be tested placed on the carrier 14, thereby realizing a functional test of the circuit board to be tested.

[0047] In some preferred embodiments, the fixing mechanism 3 includes a fixing plate 31 and a fixing driving cylinder 32. The fixing plate 31 is slidably arranged on the test frame 2 through a guide rod 33. The fixing driving cylinder 32 is arranged on the fixing plate 31, and the output end of the fixing driving cylinder 32 passes through the fixing plate 31 and connects to the test frame 2. In a specific application, after the base 11 drives one end of the substrate 12 to be inserted into a predetermined position of the FCT test equipment, the fixing driving cylinder 32 generates a driving force to drive the fixing plate 31 to move along the axial direction of the guide rod 33, so that the fixing plate 31 cooperates with the test frame 2 to clamp one end of the substrate 12, thereby fixing the substrate 12.

[0048] Specifically, a pin 13 electrically connected to the contact 121 may be provided on the fixing plate 31 , so that the fixing mechanism 3 fixes the substrate 12 while achieving electrical connection between the FCT test equipment and the test fixture 1 .

[0049] In some preferred embodiments, the pressing mechanism 4 includes a pressing plate 41 and two pressing parts 42. The two pressing parts 42 are arranged in parallel on the pressing plate 41. In a specific application, the pressing plate 41 moves downward under the driving mechanism of the FCT test equipment, and the two pressing parts 42 respectively press the two ends of the carrier 14 and the two ends of the circuit board to be tested placed on the carrier 14, so that the plurality of pins 13 pass through the carrier 14 and are electrically connected to the circuit board to be tested placed on the carrier 14, so as to realize the functional test of the circuit board to be tested.

[0050] Specifically, two parallel long holes 411 are provided on the lower pressing plate 41, and the two ends of the two pressing parts 42 are fixed to the two long holes 411 by bolts respectively. Such a design enables the distance between the two pressing parts 42 to be adjusted to adapt to different types of circuit boards.

[0051] Specifically, a guide column 412 is provided on the lower pressing plate 41, and a guide sleeve 5 is provided on the base plate 12. When the lower pressing plate 41 is pressed down, one end of the guide column 412 passes through the guide sleeve 5, and the guide sleeve 5 can guide the guide column 412, thereby ensuring the pressing accuracy of the lower pressing plate 41.

[0052] Specifically, the lower pressing plate 41 is made of a transparent material, so that it will not block the field of view of the image collector of the FCT testing equipment.

[0053] In specific applications, the above-mentioned fixing mechanism 3 and pressing mechanism 4 are electrically connected to the control system of the FCT testing equipment. The control system of the FCT testing equipment controls the actuation of the fixing mechanism 3 and the pressing mechanism 4. The control system of the FCT testing equipment can be any one of an industrial computer, a PLC or a single-chip microcomputer, which will not be repeated here.

[0054] To sum up, in one or more embodiments of the present invention, the test tool and FCT test equipment of the present invention are provided with a substrate 12 having a first circuit and a second circuit printed on both sides thereof on a base 11, and one end of the substrate 12 is designed to be exposed from the base 11, and a contact 121 electrically connected to the first circuit or the second circuit is provided on one side of one end of the substrate 12, so that when testing the circuit board, only one end of the substrate 12 needs to be inserted into the FCT test equipment without wiring, which not only saves wiring time and improves test efficiency, but also avoids the situation where errors that are prone to occur in manual wiring.
