Description

Technical Field

[0001] This utility model relates to a special device for facilitating connector assembly. Background Technology

[0002] Connectors are components that electronic engineers frequently encounter. Their primary function is to bridge gaps in circuits or connect isolated circuits, allowing current to flow and enabling the circuit to perform its intended function. Connectors are indispensable components in electronic equipment. Figure 12 The connector structure shown includes two circuit boards, which are connected by multiple spaced-apart inserts. The circuit boards and inserts are tightly fitted. Due to the large number of inserts, each insert needs to correspond one-to-one with the connection hole on the circuit board, making positioning inconvenient and inefficient during assembly. Utility Model Content

[0003] To address the shortcomings mentioned above, this utility model provides a special device for facilitating connector assembly.

[0004] To achieve the above objectives, this utility model provides a special device for facilitating connector assembly, including a base, a insert positioning seat fixed to the left side of the base, and a side limiting seat slidably disposed on the right side of the base;

[0005] The base has a positioning groove in the middle for placing the circuit board, and the left side of the base extends upward to form a protrusion, the height of which is not less than the thickness of the circuit board.

[0006] The insert positioning seat is placed above the protrusion and fixed by bolts. The right side of the insert positioning seat extends to the top of the positioning groove. The right side of the insert positioning seat is provided with an integrated positioning block. The positioning block is uniformly machined with vertically arranged insertion slots along the front-back direction for inserting inserts. After the insert is inserted, the limiting protrusion on the insert corresponds one-to-one with the connection hole on the circuit board.

[0007] The side limiting seat has a machined insertion groove I on the left side that corresponds one-to-one with the insertion groove, and the right part of the insert extends into the insertion groove I.

[0008] As a further improvement of this utility model, the depth of the positioning groove is matched with the thickness of the circuit board.

[0010] As a further improvement of this utility model, the opening of the insertion groove and the insertion groove I are chamfered.

[0011] As a further improvement of this utility model, the height of the side limiting seat is less than the height of the insert.

[0012] As a further improvement of this utility model, a slider is installed on the lower right part of the side limiting seat, and a corresponding sliding groove is machined on the lower right part of the base, with the slider and the sliding groove forming a sliding fit.

[0013] The beneficial effects of this utility model are as follows:

[0014] This device is used to assist in the positioning of circuit boards and plug-ins. The plug-in positioning seat, together with the side limiting seat, forms a double-sided positioning for the plug-ins.

[0028] like Figure 1-3 As shown, the special device for facilitating connector assembly according to this utility model includes a base 1, a insert positioning seat 2 fixed to the left side of the base 1, and a side limiting seat 3 slidably disposed on the right side of the base 1.

[0029] The base 1 has a positioning groove 12 machined in the middle for placing the circuit board 4. The depth of the positioning groove 12 matches the thickness of the circuit board 4. The left side of the base 1 extends upward to form a protrusion 13. The height of the protrusion 13 is not less than the thickness of the circuit board 4. The protrusion 13 is mainly designed to facilitate the placement and removal of the circuit board 4, leaving clearance space (see...). Figure 4 , Figure 5 );

[0030] The insert positioning seat 2 is placed above the protrusion 13 and fixed by bolts. The right side of the insert positioning seat 2 extends above the positioning groove 12. The right side of the insert positioning seat 2 is provided with an integrated positioning block 21 corresponding to the upper and lower parts. The positioning block 21 is uniformly machined with vertically arranged insertion grooves 22 along the front-back direction for inserting inserts 5. After the insert 5 is inserted, the limiting protrusions 51 on the insert 5 correspond one-to-one with the connecting holes 41 on the circuit board 4. The upper right part of the insert positioning seat 2 is machined with a recessed groove 23 for accommodating the circuit board 4 (see Figure 6-8 );

[0031] The side limiting seat 3 has a one-to-one corresponding insertion slot I 32 on the left side with insertion slot 22 (see...). Figure 9 The right side of the insert 5 extends into the insertion groove I 32. The insertion groove 22 and the opening of the insertion groove I 32 are chamfered. The height of the side limiting seat 3 is less than the height of the insert 5. A slider 31 is installed on the lower right side of the side limiting seat 3. A corresponding sliding groove 11 is machined on the lower right side of the base 1. The slider 31 and the sliding groove 11 form a sliding fit.

[0032] This device is used to assist in the positioning of circuit boards and plug-ins. The plug-in positioning seat, together with the side limiting seat, forms a double-sided positioning for the plug-ins. The lower circuit board is placed into the positioning groove of the base, and the upper circuit board is limited by the recessed groove on the plug-in positioning seat. The circuit board and plug-ins are not prone to displacement during the assembly process. The positioning is accurate, the operation is convenient, and the device is highly practical.

[0033] In practical use, for ease of understanding of this utility model, it will be described in conjunction with the accompanying drawings;

[0034] The device in this embodiment is mainly used for assembling multiple inserts between two circuit boards, such as... Figure 10 As shown, the circuit board 4 has a flat structure, and groups of connecting holes 41 are machined on the circuit board 4 along its length direction, and the connecting holes 41 are evenly distributed along the width direction of the circuit board; as shown Figure 11 As shown, the insert 5 is also a flat plate structure. The insert 5 has an integrated limiting protrusion 51 on its upper and lower sides that matches the connecting hole 41 on the circuit board 4. The limiting protrusion 51 and the circuit board 4 are interference fit. The end of the limiting protrusion 51 is chamfered.

[0035] During assembly, first remove the side limiting seat, then place the first circuit board in the positioning groove of the base. Next, insert the left side of the insert into the insertion slot of the insert positioning seat in sequence, with the limiting protrusion at the bottom of the insert corresponding to the connecting hole on the circuit board (the end of the limiting protrusion is chamfered and partially inserted into the connecting hole). After all the inserts are inserted, slide the side limiting seat into the base from the right side and push it towards the insert. The right side of the insert extends into the insertion slot I of the side limiting seat, and the side limiting seat cooperates with the insert positioning seat. The insert is positioned on both sides. Then, a second circuit board is placed on top of the insert, so that the connecting holes on the circuit board correspond one-to-one with the limiting protrusions on the upper part of the insert. The left side of the limiting plate can be inserted into the recessed groove on the upper right side of the insert positioning seat. After positioning, external force is applied to the second circuit board to apply downward pressure until the limiting protrusions on the upper and lower sides of the insert are completely pressed into the connecting holes of the upper and lower circuit boards. Then, the side limiting seat is moved to the right and removed. Finally, the assembled circuit board and insert are taken out as a whole.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
