Description

Technical Field

[0001] The utility model relates to the field of welding jigs, in particular to a connector welding jig. Background Art

[0002] A connector is a bridge that is erected between a blocked or isolated circuit in a circuit to enable current to flow and the circuit to achieve a predetermined function. A connector is an indispensable component in electronic devices, but when a connector is assembled, it needs to be welded to a cable core wire.

[0003] Currently, in wire harness processing, it is necessary to weld a cable core wire to a connector with metal pins. The current conventional welding operation method is to clamp a single connector on a jig, and then manually use an electric soldering iron to weld the cable core wire to the metal pins of the connector point by point. After that, a heat shrinkable tube is used to cover the welding point for protection, and a hot air gun is used to heat shrink the heat shrinkable tube.

[0004] However, when welding the cable core wire to the connector as described above, only a single connector is welded each time, and it is necessary to frequently replace the connector. The operation is cumbersome, and the time taken to replace the workpiece to be welded occupies a relatively large amount of time, resulting in low welding efficiency of the entire connector and cable core wire. Summary of the Utility Model

[0005] The purpose of the present utility model is to overcome the defects of the existing technology that fixing and welding a single connector is cumbersome in operation, long in welding cycle and low in working efficiency, and to provide a connector welding jig.

[0006] The purpose of the present utility model can be achieved by the following technical solutions:

[0007] A connector welding jig for clamping a connector, comprising a welding jig and a welding support column. The welding jig is detachably fixed on the welding support column. The welding jig includes a jig body, a limiting plate and a baffle plate.

[0008] The jig body is provided with a limiting groove that matches the shape of the end of the connector away from the welding end. The cross-section of the limiting groove is a T-shaped structure. One end of the limiting groove penetrates through the jig body. The limiting plate is fixed on the jig body and is located at the top of the limiting groove. The baffle plate is detachably fixed at one end of the jig body penetrated by the limiting groove. One end of the connector is clamped in the limiting groove.

[0009] Preferably, the limiting plate includes a first limiting sub-plate and a second limiting sub-plate. The first limiting sub-plate and the second limiting sub-plate are symmetrically fixed on both sides of the limiting groove. The distance between the first limiting sub-plate and the second limiting sub-plate is less than the width of the top of the limiting groove.

[0010] Preferably, both the first limiting sub-plate and the second limiting sub-plate are fixed to the fixture body by screws, and the screws are evenly distributed.

[0011] Preferably, the welding support pillar includes a fixed bottom plate, a first support pillar and a second support pillar. The first support pillar and the second support pillar are fixed on the fixed bottom plate. Clamping grooves are respectively arranged on one side of the first support pillar and the second support pillar facing each other. One end of the fixture body penetrated by the limiting groove is located in the clamping groove of the first support pillar, and the other end is located in the clamping groove of the second support pillar.

[0012] Preferably, the fixed groove is a V-shaped groove, and the V-shaped groove is matched with the shape of the end angle of the fixture body. The two groove bottom edges of the V-shaped groove are perpendicular to each other.

[0013] Preferably, one end of the fixture body away from the limiting groove is located in the fixed groove. The bottom of the fixed groove includes a limiting edge and a supporting edge. One end of the fixture body away from the limiting groove contacts the limiting edge, and the lower end of the fixture body contacts the supporting edge. The included angle between the supporting edge of the fixed groove and the horizontal plane is 30-60 degrees.

[0014] Preferably, a receiving groove is arranged on the first support pillar. The receiving groove is a V-shaped groove opening. The receiving groove is located on one side of the fixed groove, and the baffle is located in the receiving groove.

[0015] Preferably, the end of the fixture body close to the baffle is provided with a chamfered corner, and the chamfered corner is located on both sides of the limiting groove.

[0016] Preferably, a positioning groove is arranged in the limiting groove, and the positioning groove is located at the end of the limiting groove away from the baffle.

[0017] Preferably, an installation post is arranged at one end of the fixture body penetrated by the limiting groove, and an installation hole matched with the installation post is arranged on the baffle. The installation post and the installation hole are in interference fit.

[0018] Compared with the prior art, the utility model has the following advantages:

[0019] (1) When it is necessary to weld the cable core wire and the connector in this solution, the baffle is removed. The connector slides from one end of the fixture body penetrated into the limiting groove, and the connectors are arranged side by side in the limiting groove in sequence until the limiting groove is filled with connectors. Then the baffle is installed to limit the penetrated end of the limiting groove to complete the clamping of the connectors. Then the cable core wires are welded to the corresponding connectors in sequence. After completion, a heat shrinkable sleeve is sleeved on the welding part. The welding fixture is removed from the welding support pillar and placed in an oven to make the heat shrinkable sleeve shrink and fix. The baffle is removed, and the welded connectors are slid out of the limiting groove in sequence.

[0020] By setting a limiting groove on the fixture body and cooperating with a limiting plate fixed at the top of the limiting groove, a structure for clamping and fixing one end of the connector is formed. Multiple connectors can be arranged side by side in the limiting groove for batch clamping of the connectors. Moreover, a baffle provided on one side of the limiting groove can limit the sliding direction of the connector, enabling the connector to be stably clamped by the welding fixture, capable of batch clamping of the connectors, with stable and reliable clamping. On the other hand, after the heat shrinkable sleeve is completely sleeved on the welding part, the welding fixture can be removed and placed in an oven for heat shrinking. After completion, the baffle is opened, and each welded connector slides out from the limiting groove. Batch clamping of the connectors is carried out, and the overall processing of the connectors is carried out by utilizing the mobility of the welding fixture, reducing the transfer frequency of workpieces, saving processing time, and improving the welding efficiency of the connectors.

[0021] (2) In this solution, a first support column and a second support column are vertically arranged on the fixed base plate, and fixed grooves are provided at the upper ends of the first support column and the second support column, ensuring that the welding fixture is reliably and stably arranged on the welding support column, and the installation and removal of the welding fixture are convenient and fast. On the other hand, the fixed groove adopts a V-shaped groove structure to support the front end of the fixture body, making the limiting groove on the fixture body inclined, and the connector is inclined. Compared with horizontal or vertical settings, the welding of the connector to the cable core wire is more convenient and efficient. Description of the Drawings

[0034] Embodiment 1

[0035] As Figure 1As shown in the figure, this embodiment provides a connector welding tooling for clamping a connector, which includes a welding fixture 1 and a welding support 2. The welding fixture 1 is detachably fixed on the welding support 2. The welding fixture 1 includes a fixture body 11, a limiting plate 12 and a baffle 13;

[0036] The fixture body 11 is provided with a limiting groove 14 whose shape matches the end of the connector away from the welding end. The cross-section of the limiting groove 14 is a T-shaped structure. One end of the limiting groove 14 penetrates through the fixture body 11. The limiting plate 12 is fixed on the fixture body 11 and is located at the top of the limiting groove 14. The baffle 13 is detachably fixed at one end of the fixture body 11 penetrated by the limiting groove 14. One end of the connector is clamped in the limiting groove 14.

[0037] Working principle: When it is necessary to weld the cable core wire and the connector, remove the baffle 13. The connector slides into the limiting groove 14 from the penetrated end of the fixture body 11. Arrange the connectors side by side in the limiting groove 14 in sequence until the limiting groove 14 is filled with connectors. Then install the baffle 13 to limit the penetrated end of the limiting groove 14, and complete the clamping of the connector. Then weld the cable core wire to the corresponding connector in sequence. After completion, put a heat shrinkable sleeve on the welding place, remove the welding fixture 1 from the welding support 2, and place it in an oven to make the heat shrinkable sleeve shrink and fix. Remove the baffle 13, and slide the welded connectors out of the limiting groove 14 in sequence.

[0038] By setting the limiting groove 14 on the fixture body 11 and cooperating with the limiting plate 12 fixed at the top of the limiting groove 14, a structure for clamping and fixing one end of the connector is formed. Multiple connectors can be arranged side by side in the limiting groove for batch clamping of connectors. Moreover, the baffle 13 arranged on one side of the limiting groove 14 can limit the sliding direction of the connector, so that the connector is stably clamped by the welding fixture 1, and can batch clamp the connector, with stable and reliable clamping. On the other hand, after the heat shrinkable sleeve is completely put on the welding place, remove the welding fixture 1 and place it in the oven for heat shrinking. After completion, open the baffle 13, and each welded connector slides out of the limiting groove. Batch clamp the connectors, utilize the mobility of the welding fixture 1 to process the connectors as a whole, reduce the transfer frequency of workpieces, save processing time, and improve the welding efficiency of the connectors.

[0039] Specifically, as Figure 5 shown, the limiting plate 12 includes a first limiting sub-plate 121 and a second limiting sub-plate 122. The first limiting sub-plate 121 and the second limiting sub-plate 122 are symmetrically fixed on both sides of the limiting groove 14. The distance between the first limiting sub-plate 121 and the second limiting sub-plate 122 is less than the width of the top of the limiting groove 14. The first limiting sub-plate 121 and the second limiting sub-plate 122 can fix the connector in the limiting groove 14 so that it is clamped in the limiting groove 14.

[0040] Among them, both the first limiting sub-plate 121 and the second limiting sub-plate 122 are fixed on the fixture body 11 by screws, and each screw is evenly distributed. This ensures the stability and reliability of the fixation of the first limiting sub-plate 121 and the second limiting sub-plate 122.

[0041] Preferred implementation, such as Figures 2 to 4 As shown, the welding support 2 includes a fixed bottom plate 21, a first support column 22, and a second support column 23. The first support column 22 and the second support column 23 are fixed on the fixed bottom plate 21. On the opposite sides of the first support column 22 and the second support column 23, clamping grooves are respectively provided. One end of the fixture body 11 penetrated by the limiting groove 14 is located in the clamping groove of the first support column 22, and the other end is located in the clamping groove of the second support column 23.

[0042] Among them, the fixed groove is a V-shaped groove, and the V-shaped groove is matched with the end angle shape of the fixture body 11, and the two bottom edges of the V-shaped groove are perpendicular to each other.

[0043] Specifically, one end of the fixture body 11 away from the limiting groove 14 is located in the fixed groove. The bottom of the fixed groove includes a limiting edge and a supporting edge. One end of the fixture body 11 away from the limiting groove 14 contacts the limiting edge, and the lower end of the fixture body 11 contacts the supporting edge. The included angle between the supporting edge of the fixed groove and the horizontal plane is 30 - 60 degrees. Preferably, the included angle between the supporting edge of the fixed groove and the horizontal plane is 45 degrees.

[0044] The first support column and the second support column are vertically arranged on the fixed bottom plate, and a fixed groove is provided at the upper ends of the first support column and the second support column, which ensures that the welding fixture is reliably and stably arranged on the welding support, and the installation and removal of the welding fixture are convenient and fast. On the other hand, the fixed groove adopts a V-shaped groove structure to support the front end of the fixture body, so that the limiting groove on the fixture body is inclined, and the connector is inclined. Compared with the horizontal or vertical setting, the welding of the connector and the cable core wire is more convenient and efficient.

[0045] Among them, a receiving groove 24 is provided on the first support column 22. The receiving groove 24 is a V-shaped groove opening, and the receiving groove 24 is located on one side of the fixed groove. The baffle 13 is located in the receiving groove 24.

[0046] Optionally, one end of the fixture body 11 close to the baffle 13 is provided with a chamfer, and the chamfer is located on both sides of the limiting groove 14. This facilitates placing the connector into the limiting groove 14 and improves the convenience of operation. A positioning groove 15 is provided in the limiting groove 14, and the positioning groove 15 is located at one end of the limiting groove 14 away from the baffle 13. This positions the first connector in the limiting groove 14 and improves the compactness and installation stability of the aligned connectors.

[0047] Specifically, one end of the fixture body 11 penetrated by the limiting groove 14 is provided with a mounting post, and the baffle 13 is provided with a mounting hole matching the mounting post, and the mounting post and the mounting hole are in interference fit.

[0048] Open the side baffle of the welding fixture, sequentially place the connectors to be welded into the welding fixture from the side guide groove of the limiting groove, and then dial the baffle in to lock multiple connectors in the welding jig. Place the welding fixture on the fixed groove with an angular welding support post. The connectors provided on the welding fixture have a certain angle, which is convenient for subsequent welding operations. Then weld the wires to the connector pins one by one, remove the whole welding fixture from the welding support post, place it on the workbench, put the heat shrinkable tube on the solder joints, and put the welding fixture into the baking oven to quickly complete the heat shrinkage fixation of the tube heat shrinkage. Open the side baffle of the welding jig, quickly slide the connectors out of the limiting groove, and weld the connectors in batches at the same time, reducing the material flow and improving the welding processing efficiency.

[0049] The preferred specific embodiments of the present invention have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present invention without creative labor. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field of the present invention based on the concept of the present invention through logical analysis, reasoning or limited experiments on the basis of the prior art should be within the protection scope determined by the claims.
