Description

Technical Field

[0001] The utility model relates to the field of electrical connectors, in particular to a low insertion force and high extraction force connector. Background Art

[0002] As people's demand for convenient electronic products becomes increasingly apparent, it has attracted the continued attention of various manufacturers. In order to improve the competitiveness of electronic products, manufacturers must continuously enhance and expand the functions of electronic products. Therefore, various electronic products are not only moving towards a lighter and shorter appearance, but also their structure and transmission stability must continue to improve, so as to enhance user convenience in operation.

[0003] Due to the complex and ever-changing operating environments of electrical connectors, their reliability has always been a focus of attention. For example, environmental factors such as high and low temperatures, humidity, and vibration can cause electrical connector performance degradation or failure. Some existing electrical connectors lack a braking structure between the connection terminal and the conductive plate. In high-voltage and high-current transmission environments, the conductive plate and the connection terminal are easily disconnected, resulting in a poor user experience. Some electrical connectors also suffer from problems such as poor contact and unstable conductivity, which can even lead to circuit failures or safety accidents. Furthermore, existing electrical connectors on the market have only moderate heat dissipation, and high-temperature transmission conditions significantly reduce charging efficiency. Furthermore, with intensified market competition, cost control has become a major issue facing electrical connector companies. Effectively controlling costs while ensuring quality is key to business development.

[0004] How to ensure that the connection stability of the electrical connector is improved while keeping the cost under control and having a good heat dissipation effect has become a difficult problem that relevant technicians in this field urgently need to solve. Utility Model Content

[0008] The insulator includes an outer frame and an inner frame, the outer frame is provided with an inner cavity, the inner frame is fixed in the inner cavity of the outer frame, one side of the outer frame is provided with a slot for inserting a conductive sheet, and the connecting terminal is fixed on the inner frame;

[0009] The braking structure is arranged on one side of the outer frame surface adjacent to the slot; the braking structure includes a handle, a locking piece, a fixing ring, a fixing bolt and a spring piece. The outer frame is provided with a through-hole that matches the locking piece. The locking piece can be inserted into the through-hole of the outer frame to buckle the conductive sheet. The handle and the locking piece form a prying structure. There are at least two fixing rings, one is fixed on the inner surface of the handle, and the other is fixed on the bottom surface of the outer frame at a position corresponding to the handle. The two fixing rings are connected by a fixing bolt. The spring piece is installed around the fixing bolt. The spring piece is provided with a protruding end that contacts the bottom surface of the outer frame. The locking piece can be controlled to swing up and down by pressing the handle and rotating the spring piece.

[0010] Furthermore, a ventilation slot is provided at the top of the outer frame, and the ventilation slot runs through the surface of the outer frame to the connection point of the conductive sheet.

[0011] Furthermore, buckles are provided on both side ends of the inner frame, and corresponding slots are provided on the outer frame, and the inner frame is fixed in the inner cavity of the outer frame by the buckles.

[0012] Furthermore, the connecting terminal is provided with a clip, and the conductive sheet is connected to the clip after being inserted into the slot.

[0013] Furthermore, the clip is composed of two symmetrical clips, and the distance between the clips is slightly smaller than the thickness of the conductive sheet.

[0014] Furthermore, a stress hole is provided at the connection between the clip and the conductive sheet.

[0015] Furthermore, the connecting terminal has a certain elasticity. When the conductive sheet is inserted into the clip, the two clips are slightly bent outwards, and the inward deformation force clamps the conductive sheet in the middle.

[0016] Furthermore, the conductive sheet is provided with a groove that matches the locking member.

[0017] Furthermore, the handle and the locking piece are L-shaped structures, and the locking piece can be tilted up by pressing the end of the handle.

[0018] Furthermore, the fixing ring and the fixing bolt serve as the lever points of the handle. When the end of the handle is pressed, one end of the spring member contacts the surface of the outer frame to give a reaction force. When the pressing is released, the handle returns to its position under the action of the spring member.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] The utility model is provided with a braking structure on the surface of the outer frame, and the braking structure presses the conductive sheet through the locking member, so that the conductive sheet is not easy to fall off, and the connection between the connecting terminal and the conductive sheet is more stable. The manufacturing cost of the braking structure is low, and the fixing ring and the fixing bolt serve as the lever point of the handle. When the end of the handle is pressed, the locking member will tilt upward, but one end of the spring member will resist the surface of the outer frame to give a reaction force. When the conductive sheet is connected to the connecting terminal, the pressing is cancelled, and the handle returns to its position under the action of the spring member, and the locking member also presses the conductive sheet under the action of the spring member. The utility model is also provided with ventilation holes in the outer frame, and the ventilation holes penetrate to the conductive sheet, which has the function of dissipating heat to the conductive sheet by improving air circulation.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] See also Figure 1 and Figure 5 , providing a low insertion force and high extraction force connector, comprising a braking structure 12, a connecting terminal 13 and an insulator;

[0035] The insulator includes an outer frame 11 and an inner frame 16. The outer frame 11 has an inner cavity, and the inner frame 16 is fixed in the inner cavity of the outer frame 11. The inner frame 16 has buckles 161 on both sides, and the outer frame 11 has corresponding slots 111. The inner frame 16 is fixed in the inner cavity of the outer frame 11 by the buckles 161. One side of the outer frame 11 has a slot 112 for inserting the conductive sheet 14.

[0036] Specifically, the inner frame 16 includes a frame body 162 and a clip 161. The clip 161 is provided at both side ends of the frame body 162. The clip 161 is a protruding block. The frame body 162 of the inner frame 16 has the same width as the inner cavity of the outer frame 11. The clips 161 at both ends protrude and are inserted into the card slots 111 of the outer frame 11. The outer frame 11 plays a protective role for the connecting terminal 13 and the conductive sheet 14, and the inner frame 16 can serve as a fixed support for the connecting terminal 13 and the conductive sheet 14.

[0037] See also Figure 8 In order to reduce the volume of the connector, the connecting terminals 13 are fixed on the inner frame 16 in an up-and-down staggered manner, and the conductive sheets 14 are arranged in parallel. The conductive sheets 14 are connected to the up-and-down staggered connecting terminals 13 in sequence, which not only reduces the volume of the connector but also improves the connection stability.

[0038] See also Figure 5and Figure 7 The connecting terminal 13 is fixed to the inner frame 16. The connecting terminal 13 is provided with a clip 131. The conductive sheet 14 is connected to the clip 131 after being inserted into the slot 112. The clip 131 consists of two symmetrical clips. The distance between the clips is slightly smaller than the thickness of the conductive sheet 14. A stress hole 132 is provided at the connection between the clip 131 and the conductive sheet 14. The connecting terminal 13 has a certain elasticity. When the conductive sheet 14 is inserted into the clip 131, the two clips are slightly bent outward, and the inward deformation force clamps the conductive sheet 14 in the middle.

[0039] See also Figure 4 and Figure 7 Specifically, the head end of the connecting terminal 13 is provided with a connecting hole 133 and a contact ring 134. The connecting hole 133 is fixed to the outer end of the support plate 135, and the contact ring 134 is fixed to the board surface of the support plate 135. The contact ring 134 is two wire pressing holes. After the connecting wire 15 passes through the connecting hole 133, the copper wire in the connecting wire 15 is shunted at the contact ring 134. The contact ring 134 compacts the copper wire, so that the copper wire is more fully connected to the connecting terminal 13. The connecting terminal 13 is connected to the conductive sheet 14 through the clip 131.

[0040] See also Figure 7 、 Figure 9 and Figure 10 To prevent unevenness between the connection surface of the clip 131 and the conductive sheet 14 caused by process problems, which would result in a small connection area between the clip 131 and the conductive sheet 14, a stress hole 132 is provided at the connection between the clip 131 and the conductive sheet 14. In the existing market, without a stress hole, the connection between the clip 131 and the conductive sheet 14 is only via the third contact piece 1323. The provision of the stress hole can divide the clip 131 into a first contact piece 1321 and a second contact piece 1322. If the clip 131 and the conductive sheet 14 are at an angle, the third contact piece 1323 can only maintain one contact point (the third contact point 23) with the conductive sheet 14. However, due to the slight deformation of the stress hole, the clip 131 and the conductive sheet 14 maintain two contact points (the first contact point 21 and the second contact point 22), thereby increasing the contact area between the clip 131 and the conductive sheet. In addition, the stress hole 132 can increase the buffering of vibration between the conductive wire and the clip 131, thereby improving the connection stability.

[0041] Please refer to 1. Figure 2 and Figure 3, the braking structure 12 is provided on one side of the surface of the outer frame 11 adjacent to the slot 112; the braking structure 12 includes a handle 122, a locking member 121, a fixing ring 123, a fixing bolt 124 and a spring member 125, the outer frame 11 is provided with a through hole that matches the locking member 121, the locking member 121 can be inserted into the groove to buckle the conductive sheet 14, the handle 122 and the locking member 121 form a prying structure, the handle 122 and the locking member 121 are L-shaped structures, pressing the end of the handle 122 can tilt the locking member 121, there are at least two fixing rings 123, one is fixed to the inner surface of the handle 122, and the other is fixed to the bottom surface of the outer frame 11 and the handle 1 22 corresponding position, the two fixing rings 123 are connected by a fixing bolt 124, and the spring member 125 is installed around the fixing bolt 124. The spring member 125 has a protruding end that contacts the bottom surface of the outer frame 11. By pressing the handle 122 and rotating the spring member 125, the up and down swing of the locking member 121 can be controlled. The fixing ring 123 and the fixing bolt 124 serve as the leverage points of the handle 122. When the end of the handle 122 is pressed, one end of the spring member 125 contacts the surface of the outer frame 11 to give a reaction force. When the pressing is released, the handle 122 returns to its position under the action of the spring member 125. The conductive sheet 14 is provided with a groove that matches the locking member 121.

[0042] Specifically, the default state of the braking structure 12 is that the spring member 125 buckles the locking member 121, and the bottom side of the locking member 121 conflicts with the inner frame 16. Press the handle 122, and use the fixing hole and the fixing bolt 124 as a lever point to lift the locking member 121. After the conductive sheet 14 is inserted into the slot 112 and connected to the connecting terminal 13, release the pressure. Since one end of the spring member 125 conflicts with the inner wall of the perforation of the outer frame 11, the spring member 125 deforms and recovers after releasing the pressure, driving the handle 122 to rotate, and at the same time pressing the locking member 121 downward, the locking member 121 passes through the outer frame 11 and matches the groove of the conductive sheet 14.

[0043] See also Figure 6 A ventilation groove is provided at the top of the outer frame 11. The ventilation groove runs through the surface of the outer frame 11 to the connection of the conductive sheet 14. The ventilation groove is connected to the inner cavity of the outer frame 11. The ventilation groove increases the air circulation in the inner cavity of the outer frame 11 and has a heat dissipation effect on the conductive sheet 14 and the connecting terminal 13.

[0044] The utility model is provided with a braking structure 12 on the surface of the outer frame 11, and the braking structure 12 presses the conductive sheet 14 through the locking member 121, so that the conductive sheet 14 is not easy to fall off, and the connection between the connecting terminal 13 and the conductive sheet 14 is more stable. The manufacturing cost of the braking structure 12 is low, and the fixing ring 123 and the fixing bolt 124 serve as the leverage point of the handle 122. When the end of the handle 122 is pressed, the locking member 121 will tilt upward, but one end of the spring member 125 will resist the surface of the outer frame 11 to give a reaction force. When the conductive sheet 14 is connected to the connecting terminal 13, the pressing is released, and the handle 122 returns to its position under the action of the spring member 125, and the locking member 121 also presses the conductive sheet 14 under the action of the spring member 125. The utility model also has a ventilation hole 113 on the outer frame body. The ventilation hole 113 penetrates to the conductive sheet 14 and has the function of dissipating heat from the conductive sheet 14 by improving air circulation. The utility model has the characteristics of stable connection, convenient operation, and strong heat dissipation.

[0045] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
