Description

Technical Field

[0001] This application relates to the field of PCB connector technology, and more particularly to a separation device for PCB board connectors. Background Technology

[0002] With the increasing demands for modularity and miniaturization in electronic devices, the integration level of electronic devices is becoming higher and higher, and the functions required of modules are also increasing. However, the physical size of the modules cannot be increased, so multiple PCBs are used to achieve this. Communication between multiple PCBs is generally achieved through cables or inter-board connectors. As the number of signals for inter-board communication increases, several problems arise with cable connections. First, the soldering area on the board occupies a large area, making board layout difficult. Second, the more cables are soldered, the more difficult the manufacturing process becomes. High-density, multi-core connectors can effectively solve the above problems, so high-density inter-board connectors are now widely used.

[0003] The plugs and sockets of inter-board connectors are mounted on the PCB using crimping or soldering. The pins and sockets of the inter-board connectors experience a certain insertion and extraction force when they are mated together. This force is essential to ensure tight contact between the connectors and prevent data transmission failures during vibration. The more pins a connector has, the greater the insertion and extraction force.

[0004] When plugging and unplugging two PCBs, due to manual operation, it is impossible to control the parallelism between the two PCBs, and they are easily tilted. Often, due to excessive tilt angle, the pins are bent, the plastic shell of the connector is cracked, and thus the connector is damaged. Utility Model Content

[0005] To address the shortcomings of the prior art, this application provides a PCB board connector separation device that can smoothly and uniformly separate the daughter PCB from the base PCB, thereby improving the product qualification rate.

[0006] To achieve the above objectives, the present invention employs the following technology: A PCB board connector separation device includes a base plate with a pair of parallel guide rails on it, between which a module housing is placed. A pair of parallel vertical plates are also arranged on the base plate, with a mounting plate connected between them. The mounting plate has a mounting seat, which is hinged to one end of an elbow clamp. One end of the elbow clamp is also hinged to one end of a V-shaped rod. The other end of the V-shaped rod is hinged to a vertically movable vertical rod. A horizontal plate is connected to the bottom of the vertical rod, with its length direction corresponding to the width direction of the module housing. Both ends of the horizontal plate slide along two guide posts, which are vertically positioned on the base plate. Multiple connecting hooks are symmetrically arranged on both sides of the horizontal plate, and the spacing between the connecting hooks on both sides is adjustable.

[0007] The beneficial effects of this utility model are as follows: by rotating the elbow clamp, the daughter card PCB can be separated from the base plate PCB smoothly and at a uniform speed, thereby separating the inter-board connectors soldered on the daughter card and the base plate. During the separation process, the force balance of the connector can be guaranteed and it will not tilt. The pins will not bend or deform due to lateral force, thus improving the product yield.

[0012] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0013] This application provides a device for separating PCB board connectors. The PCB board includes a daughter PCB and a base PCB. The inter-board connector consists of a plug soldered to the bottom of the daughter PCB and a socket soldered to the top of the base PCB, with the plug and socket connected together. Figures 1-3 As shown, a PCB board connector separation device includes a base plate 1 with a pair of parallel guide rails 2 on it. A module housing 3 is placed between the guide rails 2. The base plate PCB screws are installed on the module housing 3. A pair of parallel vertical plates 4 are also arranged on the base plate 1. A mounting plate 5 is connected between the vertical plates 4. A mounting seat 51 is provided on the mounting plate 5. The mounting seat 51 is hinged to one end of an elbow clamp 52. One end of the elbow clamp 52 is also hinged to one end of a V-shaped rod 53. The other end of the V-shaped rod 53 is hinged to a vertically movable vertical rod 54. A horizontal plate 55 is connected to the bottom of the vertical rod 54. The length direction of the horizontal plate 55 corresponds to the width direction of the module housing 3. The two ends of the horizontal plate 55 are slidably inserted through two guide posts 6. The guide posts 6 are vertically arranged on the base plate 1. Multiple connecting hooks 56 are symmetrically arranged on both sides of the horizontal plate 55. The spacing between the connecting hooks 56 on both sides is adjustable.

[0014] In application, the operator controls the elbow clamp 52 to rotate, thereby adjusting the vertical movement of the cross plate 55, and consequently, the vertical movement of the connecting hook 56. After adjusting the connecting hook 56 to a suitable height, the distance between the two connecting hooks 56 is adjusted, such as... Figure 1 As shown, the connecting hook 56 is hooked to the daughter card PCB, and then the elbow clamp 52 is rotated to move the connecting hook 56 upward. The connecting hook 56 drives the daughter card PCB to move upward, so as to separate the daughter card PCB from the base plate PCB.

[0015] Specifically, such as Figure 1 As shown, the connecting hook 56 is fixed to the horizontal plate 55 by hand-tightening the non-detachable nut 7, thereby realizing the adjustment of the distance between the two connecting hooks 56 to suit daughter card PCBs of different widths.

[0016] Specifically, such as Figure 1 and Figure 3 As shown, locking strips 31 are provided on both sides of the module housing 3. Both guide rails 2 are U-shaped structures with their openings facing each other. The locking strips 31 slide through the guide rails 2 and are used to fix the module housing 3 to the guide rails 2. The module housing 3 can be moved back and forth to a suitable position according to the position of the sub-clip in the module, and then locked with the locking strips 31, thus having a certain degree of universality for different module housings 3.

[0017] Specifically, such as Figure 2 and Figure 3 As shown, the locking bar 31 includes an upper horizontal bar 311 arranged parallel to the length direction of the module housing 3. Below the upper horizontal bar 311, along its length, are sequentially arranged a first lower horizontal bar 312, a second lower horizontal bar 313, and a third lower horizontal bar 314. The second lower horizontal bar 313 is movable along the height direction of the module housing 3, and the first lower horizontal bar 312 is movable along the length direction of the module housing 3. The second lower horizontal bar 313 has a trapezoidal structure with the smaller end facing upward, and second inclined surfaces are formed at both ends. The surfaces of the first lower horizontal bar 312 and the third lower horizontal bar 314 facing the second lower horizontal bar 313 respectively form a first inclined surface and a third inclined surface for engaging with the corresponding second inclined surfaces. More specifically, the position of the upper horizontal bar 311 can be adjusted by a locking screw 315 threaded through it. In use, the locking screw 315 is rotated using a tool to move the first lower horizontal bar 312 toward the second lower horizontal bar 313. Through the sliding engagement of the first inclined surface and the second inclined surface, and the second inclined surface and the third inclined surface, the second lower horizontal bar 313 is moved away from the upper horizontal bar 311, thereby pressing the upper horizontal bar 311 against the inner top surface of the guide rail 2 and pressing the second lower horizontal bar 313 against the inner bottom surface of the guide rail 2, thus achieving locking.

[0018] When replacing module housing 3, to facilitate the removal of module housing 3 from guide rail 2, more specifically, as follows: Figure 1 and Figure 3 As shown, a puller 32 is provided at one end of the module housing 3.

[0019] Specifically, the outer wall of the connecting hook 56 is fitted with a rubber pad to ensure that no wear occurs when the connecting hook 56 contacts the daughter card PCB.

[0020] In application, the above description is only a preferred embodiment of this application and is not intended to limit this application. Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application.
