Description

Technical Field

[0001] The utility model belongs to the technical field of electronic seals, and particularly relates to a charging connector. Background Art

[0002] Since electronic seals are internally provided with electronic components, they also need to be internally provided with a power source to supply power to the internal electronic components to ensure the long-term stable operation of the electronic seals. For some electronic seals that need to be used multiple times, a suitable charging connector needs to be equipped to charge the power source in the electronic seal when the power source runs out of power.

[0003] The Chinese utility model patent with the publication number CN216929079U discloses an electronic seal connector, which includes a connection seat. A groove is provided in the middle position of the connection seat, and positioning grooves are symmetrically arranged on both side walls of the groove. The positioning groove is a groove hole structure with a rectangular cross-section. A charging connection column is arranged in the middle position of the groove, and the charging connection column is clamped with the charging port of the electronic seal. A positioning structure is arranged at the position between the two positioning grooves on one side of the groove. The four corners of the lower end surface of the connection seat are connected and fixed with a bottom adsorption structure. The heat dissipation grooves on both sides of the charging connection column facilitate the flow of air, so that the heat generated during charging between the charging connection column and the electronic seal can be discharged in time. This design greatly improves the heat dissipation efficiency and prevents the electronic seal from being damaged due to the accumulation of heat and inability to dissipate.

[0004] The technical solution provided by the above patent has the following deficiencies when in use:

[0005] This technical solution uses the method of "the clamping column 63 extending out of the positioning cylinder 61 is clamped with the concave holes provided on both sides of the electronic seal" to tightly connect the electronic seal and the charging connector. This method easily causes the clamping column 63 to scratch the electronic seal. Moreover, although this method is provided with "heat dissipation grooves 3" for heat dissipation, due to passive heat dissipation, the gas around the "heat dissipation grooves 3" does not flow, resulting in poor heat dissipation effect. Summary of the Utility Model

[0006] The purpose of the present utility model is to propose a charging connector in order to solve the problems that the existing charging connectors are prone to scratching the electronic seal and have poor heat dissipation effect.

[0007] In order to achieve the above purpose, the present utility model adopts the following technical solutions:

[0008] A charging connector includes a workpiece and a charging seat. The charging seat is provided with charging contacts for charging the workpiece. The charging contacts are electrically connected to an external power source through wires. The inside of the charging seat is hollow and is communicated with the air inlet of a negative pressure device through a pipeline;

[0009] The upper surface of the charging base is fixedly connected with a soft pad. Strip-shaped holes are formed in both the upper surface of the charging base and the soft pad. A plurality of convex strips arranged at equal intervals are formed on the upper surface of the soft pad. An adsorption channel is formed between two adjacent convex strips. The adsorption channel is communicated with the inner cavity of the charging base through the strip-shaped hole.

[0010] Preferably, the convex strip has a wavy structure.

[0011] Preferably, a switch for adjusting the on-off of the strip-shaped hole is further arranged on the charging base;

[0012] The switch includes a rigid tube arranged horizontally, a sealing plate and a plugging plate. One end of the rigid tube penetrates and extends into the interior of the charging base and is fixedly connected with the plugging plate. The rigid tube is slidably and sealingly connected with the charging base. The sealing plate is fixedly arranged on the axial extension line of the other end of the rigid tube;

[0013] When the switch is closed, the plugging plate plugs the strip-shaped hole, and the inner cavity of the charging base is communicated with the external environment through the rigid tube;

[0014] When the switch is opened, the adsorption channel is communicated with the inner cavity of the charging base through the strip-shaped hole, and the other end of the rigid tube abuts against the sealing plate.

[0015] Preferably, the switch further includes a sealing sleeve. The sealing sleeve is embedded and installed on one side of the charging base. The rigid tube is slidably and sealingly connected with the sealing sleeve.

[0016] Preferably, two push rods arranged symmetrically are fixedly connected to the other end of the rigid tube. The push rods are arranged along the radial direction of the rigid tube.

[0022] 2.

[0032] The present utility model will be described below in conjunction with specific embodiments.

[0033] As Figure 1As shown in the figure, this embodiment provides a charging connector, which is mainly used for charging an electronic seal. The charging connector includes a workpiece 10 and a charging base 20. In this embodiment, the workpiece 10 refers to an electronic seal. On the upper surface of the charging base 20, there are charging contacts 41 for charging the workpiece 10. The charging contacts 41 are electrically connected to an external power source through a wire 42. When in use, by bringing the contacts on the workpiece 10 into contact with the charging contacts 41, the electrical connection between the charging contacts 41 and the workpiece 10 can be achieved, and then the workpiece 10 can be charged.

[0034] The interior of the charging base 20 is hollow and is connected to the air inlet of a negative pressure device through a pipeline. The negative pressure device can extract the air inside the charging base 20, reducing the air pressure inside the charging base 20, so that the air in the external environment quickly enters the interior of the charging base 20 through the strip-shaped holes 211 under the action of air pressure, thereby forming a negative pressure to adsorb the workpiece 10. The specific working principle is as follows:

[0035] As Figures 1 to 2 shown in the figure, a soft pad 21 is fixedly connected to the upper surface of the charging base 20. Strip-shaped holes 211 are provided on both the upper surface of the charging base 20 and the soft pad 21. The strip-shaped holes 211 are located in the middle of the soft pad 21. On the upper surface of the soft pad 21, a number of equally spaced convex strips 212 are integrally formed. The soft pad 21 and the convex strips 212 can be made of rubber material. The rubber soft pad 21 and convex strips 212 are soft in texture, which can avoid direct contact between the charging base 20 and the workpiece 10, achieving the purpose of protecting the workpiece 10. An adsorption channel 213 is formed between two adjacent convex strips 212, and the strip-shaped holes 211 are located in the middle of the adsorption channel 213. The adsorption channel 213 is connected to the inner cavity of the charging base 20 through the strip-shaped holes 211. The convex strips 212 are in a wavy shape, which can increase the lateral and longitudinal friction between the workpiece 10 and the soft pad 21, improving the stability of the workpiece 10 on the charging base 20.

[0036] When in use, place the workpiece 10 on a number of convex strips 212 and bring the contacts on the workpiece 10 into contact with the charging contacts 41, then the electrical connection between the charging contacts 41 and the workpiece 10 can be achieved, realizing the charging operation of the workpiece 10. During this process, the negative pressure device can extract the air inside the charging base 20 through the pipeline, so that the air in the external environment quickly enters the interior of the charging base 20 through the strip-shaped holes 211. At this time, since the workpiece 10 is located on a number of convex strips 212, an adsorption force will be generated in each adsorption channel 213, realizing the adsorption and fixation of the workpiece 10. And because the air quickly flows through the adsorption channel 213, the heat generated when the workpiece 10 is charged can be quickly taken away, preventing the workpiece 10 from generating high temperature due to charging. Further, the charging contacts 41 in this embodiment are also located in the adsorption channel 213, so the high temperature generated at the position of the charging contacts 41 can also be reduced.

[0037] In the above scheme, the adsorption force generated by the negative pressure equipment is used to complete the fixation between the workpiece 10 and the charging base 20. On the one hand, it can prevent the charging base 20 from scratching the workpiece 10, and it also facilitates the placement of the workpiece 10. On the other hand, the high-speed air flow in the adsorption channel 213 can also take away the heat generated during the charging process of the workpiece 10, so that the workpiece 10 is always kept in a healthy temperature environment during the charging process.

[0038] like Figures 1 to 4 As shown, a switch 30 for adjusting the on / off state of the strip-shaped hole 211 is disposed on the side of the charging stand 20 .

[0039] Specifically, the switch 30 includes a horizontally arranged hard tube 32, a sealing plate 33 and a sealing plate 34, wherein the sealing plate 33 is a rectangular plate, and the length direction of the sealing plate 33 is parallel to the length direction of the strip hole 211, while the axial direction of the hard tube 32 is perpendicular to the length direction of the sealing plate 33.

[0040] like Figures 3 to 4 As shown, one end of the hard tube 32 extends through the interior of the charging seat 20 and is fixedly connected to the blocking plate 34, and the blocking plate 34 abuts against the inner top wall of the charging seat 20. The hard tube 32 is slidably and sealedly connected to the charging seat 20, and the sealing plate 33 is fixedly arranged on the axial extension line of the other end of the hard tube 32; Figure 3 As shown, at this time, the blocking plate 34 blocks the strip hole 211, and the other end of the hard tube 32 is not in contact with the sealing plate 33, that is, the switch 30 is in a closed state at this time, and the inner cavity of the charging seat 20 is connected to the external environment through the hard tube 32. At this time, no negative pressure is generated in the adsorption channel 213, so it is convenient to place the workpiece 10 on the charging seat 20, and the workpiece 10 will not hit the charging seat 20 due to the adsorption force. In addition, since there is no adsorption force, it is also convenient to adjust the position of the workpiece 10 so that the contact on the workpiece 10 is aligned and in contact with the charging contact 41, and it is also convenient to pick up the workpiece 10 from the charging seat 20; Figure 4 As shown, the sealing plate 34 is moved away from the bottom of the strip hole 211, and the other end of the hard tube 32 is against the sealing plate 33, that is, the switch 30 is in the open state at this time, and the adsorption channel 213 is connected with the inner cavity of the charging seat 20 through the strip hole 211; in other words, when the switch 30 is in the closed state, since there is no adsorption force in the adsorption channel 213 at this time, it can be used to place the workpiece 10 on the charging seat 20, or to remove the workpiece 10 from the charging seat 20. When the switch 30 is in the open state, it is used to charge the workpiece 10, that is, the setting of the switch 30 has a very good promoting effect on the entire charging process of the workpiece 10.

[0041] The hard tube 32 , the sealing plate 33 and the blocking plate 34 can all be made of hard materials such as stainless steel.

[0042] Further, the switch 30 further includes a sealing sleeve 31. The sealing sleeve 31 is embedded and installed on one side of the charging base 20. The rigid tube 32 is slidably and sealingly connected to the sealing sleeve 31. Specifically, the sealing sleeve 31 includes a sleeve and a plurality of sealing rings fixed on the inner wall of the sleeve. The sealing rings are sleeved on the outer side of the rigid tube 32 in an interference fit manner, thereby realizing the slidable and sealing connection between the sleeve and the rigid tube 32.

[0043] Further, two symmetrically arranged push rods 321 are fixedly connected to the other end of the rigid tube 32. The push rods 321 are arranged along the radial direction of the rigid tube 32 to facilitate the user to push or pull the rigid tube 32 by using the push rods 321.

[0044] The sealing plate 33 is fixedly connected to the charging base 20 through a connecting plate 331, and a sealing gasket 332 is fixed on the side surface of the sealing plate 33 facing the rigid tube 32. The diameter of the sealing gasket 332 is larger than the inner diameter of the rigid tube 32. The sealing gasket 332 can improve the sealing performance between the rigid tube 32 and the sealing plate 33.

[0045] In the above solution, by providing the switch 30, when the switch 30 is in the closed state, since there is no adsorption force in the adsorption channel 213 at this time, it can be used to place the workpiece 10 on the charging base 20 or to remove the workpiece 10 from the charging base 20, which is labor-saving and convenient; when the switch 30 is in the open state, it is used for charging the workpiece 10 to fix the workpiece 10 by using the adsorption force in the adsorption channel 213 and improve the stability of the workpiece 10; at the same time, by pulling the rigid tube 32, the opening and closing of the switch 30 can be quickly adjusted, and the operation is highly convenient.

[0046] The charging base 20 includes a housing 201 and a bottom plate 202. The housing 201 is in the shape of a rectangular box with an open bottom, and the bottom plate 202 is sealingly installed at the open bottom position of the housing 201.
