DETAILED DESCRIPTION

[0029] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the accompanying drawings. The accompanying drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0030] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0032] In the embodiment of the present utility model, a connecting rod fixing device and a fixture module are provided. Please refer to Figure 1-4 , the connecting rod fixing device comprises a mounting seat 10, a first connecting rod 20, a second connecting rod 30 and a third connecting rod 40;

[0033] The first connecting rod 20 is hinged to the mounting seat 10 and the second connecting rod 30 respectively, and the two ends of the third connecting rod 40 are hinged to the mounting seat 10 and the second connecting rod 30 respectively; moving the second connecting rod 30 can drive the first connecting rod 20 and the third connecting rod 40 to move.

[0034] According to the connecting rod fixing device in the above embodiment, the mounting seat 10 must be fixed first, and then the second connecting rod 30 must be moved. The second connecting rod 30 is hinged to the first connecting rod 20, and the first connecting rod 20 is hinged to the mounting seat 10. Therefore, the second connecting rod 30 forces the first connecting rod 20 to rotate around the hinge with the mounting seat 10. At this time, the hinge between the second connecting rod 30 and the first connecting rod 20 makes a circular arc motion around the hinge of the first connecting rod 20 around the mounting seat 10. The two ends of the third connecting rod 40 are respectively hinged to the mounting seat 10 and the second connecting rod 30, so that the rotation directions of the first connecting rod 20 and the second connecting rod 30 can always remain opposite. When fixing the object 1 to be fixed, it is necessary to overcome the gravity of the first connecting rod 20 and the second connecting rod 30 at the same time, thereby ensuring that the object 1 to be fixed will not loosen.

[0035] It should be noted that the rotation planes of the first connecting rod 20 , the second connecting rod 30 and the third connecting rod 40 are parallel to each other or overlap on the same plane.

[0036] In the prior art, a simple lever rotation is also used to press the object to be fixed 1 and prevent the tester from touching the object to be fixed 1. However, there are some problems: First, the problem of counterweight. The lever needs a certain weight to abut against the object to be fixed 1, which causes the tester to hold the lever with his hand when taking and placing the object to be fixed 1. Second, in order to facilitate lifting the lever, the handheld end of the lever is generally longer. When the lever is rotated downward, it will abut against the supporting platform 100, and the lever cannot be rotated further.

[0037] The connecting rod fixing device in this embodiment can ensure that the fixed object is in place when it is taken in and out, does not need to be maintained by hand, and is not affected by the interference of the carrying platform 100.

[0038] In some specific embodiments, please refer to Figure 1 and Figure 2 A holding member 50 is also provided, and the holding member 50 is arranged at an end of the first connecting rod 20 away from the second connecting rod 30.

[0039] The pressing member 50 is generally arranged perpendicular to the first connecting rod 20, so that when the pressing member 50 presses the object 1 to be fixed, it is generally in a state perpendicular to the horizontal plane, and the force point of the object 1 to be fixed is located in the middle area of ​​the object 1 to be fixed. If one end of the first connecting rod 20 is used to press directly on the object 1 to be fixed, since the movement of the first connecting rod 20 is to rotate around the mounting seat 10, the end of the first connecting rod 20 away from the second connecting rod 30 usually cannot contact the object 1 to be fixed, which will cause uneven force on the object 1 to be fixed, thereby causing the object 1 to be fixed to tilt.

[0040] In some specific embodiments, the pressing member 50 is made of a flexible material at one end away from the first connecting rod 20 .

[0041] The flexible material can have a buffering effect, thereby avoiding damage to the object to be fixed 1. Generally speaking, the flexible material is an insulating material such as rubber and silicone. Rubber and silicone are not only soft, but also insulating, thereby avoiding the connection rod fixing device in the utility model from being conductive.

[0042] In some specific embodiments, please refer to Figure 3 A sliding groove 210 is provided on the first connecting rod 20 , and the holding member 50 can move along the length direction of the sliding groove 210 .

[0043] In this embodiment, a slide groove 210 is provided on the first connecting rod 20, and the pressing member 50 is moved in the slide groove 210, so that when pressing the object 1 to be fixed, the pressing member 50 abuts against the middle area of ​​the object 1 to be fixed, so that the object 1 to be fixed is subjected to uniform force.

[0044] In some specific embodiments, the holding member 50 also includes a first fastener 510, a second fastener 520, a main body 530 and a nut 540. The nut 540 can be threadedly connected to the main body 530. The first fastener 510 is fixed to the main body 530. The second fastener 520 is squeezed by rotating the nut 540 so that the first fastener 510 and the second fastener 520 are clamped on the first connecting rod 20.

[0045] In this embodiment, after the pressing member 50 is moved to a designated position in the slide groove 210, the first fastener 510 and the second fastener 520 are mutually clamped, so that the pressing member 50 is fixed at a suitable position on the first connecting rod 20. Generally speaking, the first fastener 510 needs to be fixed on the body 530, and then the nut 540 rotates to squeeze the second fixing member. It should be noted that the first fastener 510 can be located above the first connecting rod 20, or below the first connecting rod 20.

[0046] In addition, the first connecting rod 20 can actually be equipped with the same nut 540, and the first fastener 510 and the second fastener 520 can move toward each other by squeezing the two nuts 540. And because the nuts 540 are screwed on the body 530, the two nuts 540 are equivalent to fixing the body 530.

[0047] In some specific embodiments, the mounting base 10 has an escape position 110 to facilitate the hinge of the third link 40 and the second link 30 to move downward.

[0048] The avoidance position 110 is generally disposed between two hinges on the mounting seat 10 , thereby increasing the movable space of the third connecting rod 40 .

[0049] In some specific embodiments, when the hinges of the third link 40 and the second link 30 abut against the mounting seat 10 , the first link 20 and the second link 30 are both vertical.

[0050] In this embodiment, the second connecting rod 30 is rotated counterclockwise until the second connecting rod 30 is in a vertical state. At this time, the first connecting rod 20 is rotated clockwise and is also in a vertical state. This not only releases the restraint on the object to be fixed 1, but also allows the first connecting rod 20 to give up enough space for taking and placing the object to be fixed 1.

[0051] Compared with other fixing structures in the prior art, the connecting rod fixing device in this embodiment is obviously more convenient to operate and has the advantages of compact structure and reasonable installation.

[0052] Please refer to Figure 4 In this state, the center of gravity of the first connecting rod 20, the second connecting rod 30, and the third connecting rod 40 all fall on the mounting seat 10, so this state can be maintained all the time.

[0053] In some specific embodiments, the second connecting rod 30 is wrapped with insulating material.

[0054] The main materials of the first connecting rod 20, the second connecting rod 30, the third connecting rod 40 and the mounting base 10 are generally made of metal. The second connecting rod 30 includes insulating material to prevent the experimenter from getting an electric shock. This is because most electronic products have capacitors, inductors and other devices. Even if the electronic product is powered off, it will still be charged for a short time.

[0055] In some specific embodiments, the mounting base 10 is further provided with a mounting hole 120 , and the mounting hole 120 is used to fix the mounting base 10 .

[0056] Generally, at least two mounting holes 120 are provided to facilitate fixing to the carrying platform 100 .

[0057] In the second aspect, a fixture module is provided in an embodiment of the utility model, which comprises a carrying platform 100 and any connecting rod fixing device of the first aspect, wherein the connecting rod fixing device is fixed on the carrying platform 100, and the carrying platform 100 is used for an object 1 to be fixed.

[0058] According to the fixture module in the above embodiment, the fixture module has the connecting rod fixing device of the first aspect. Therefore, the mounting seat 10 of the connecting rod fixing device can be fixed on the carrying platform 100, and the carrying platform 100 is preset with various electrical interfaces to match the object to be fixed 1. Thus, when taking and placing the object to be fixed 1, it is achieved that the object to be fixed 1 will not be accidentally contacted.

[0059] Generally, a plurality of electrical contacts are preset on the carrying platform 100 . When the object 1 to be fixed is placed in a designated position on the carrying platform 100 , the electrical contacts are electrically connected to the object 1 to be fixed.

[0060] It should be noted that the object to be fixed 1 is generally provided with a positioning hole, and the carrying platform 100 is generally provided with a positioning column. Through the cooperation of the positioning column and the positioning hole, the object to be fixed 1 can be quickly and accurately installed on the carrying platform 100. The carrying platform 100 is also provided with many electronic component modules inside, thereby providing a test environment. For example, to increase the peak current, peak voltage, high frequency conversion test, etc.

[0061] In some specific embodiments, please refer to Figure 1 and Figure 5 The fixture module also includes a prying member 60, which includes a mounting portion 610 and a first section 620 and a second section 630 located on both sides of the mounting portion 610, and the mounting portion 610 is rotatably mounted on the carrying platform 100; when the object 1 to be fixed is electrically connected to the carrying platform 100, the object 1 to be fixed presses the first section 620, and the second section 630 is away from the carrying platform 100.

[0062] The PCB test point is welded in the form of a clip. Since the device has a large number of ping pins, when all the ping pins are in contact and pressed against the clip, the force generated is very large, and it is very difficult to manually pull out the device, so it is necessary to use external force to pull out the device. When it is necessary to pull out the object to be fixed 1, just press down the second section 630, so that the first section 620 is tilted, thereby driving the object to be fixed 1 to disconnect from the carrier platform 100.

[0063] In some specific embodiments, the second segment 630 is longer than the first segment 620 .

[0064] In this embodiment, the length of the second section 630 is longer than that of the first section 620, so that the tester can use less force, which is mainly due to the use of the lever principle.

[0065] Generally, there are two prying members 60 , which are respectively located on two sides of the object 1 to be fixed.

[0066] Finally, it should be noted that in general, the outer shell of the fixture module is wrapped with a layer of plastic, which can not only achieve aesthetics but also prevent the circuit board from being scratched.

[0067] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0068] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent application. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
