Description

Technical Field

[0001] The present application relates to the technical field of connectors, and in particular to a dual-pressure terminal connector. Background Art

[0002] A connector is an electromechanical component used to connect a circuit to an appropriate mating component to achieve circuit connection and disconnection. The connector includes a male plug and a female plug. The male plug is inserted into the female plug, and both the male plug and the female plug are connected to the wiring part to achieve circuit connection.

[0003] In the related art, the connector includes a male plug and a female plug. The male plug has two U-shaped strips bent on it. The U-shaped strips are bent toward the male plug. The bent position of the U-shaped strips abuts against the wiring part to fix the wiring part and the male plug. The female plug is provided with a receiving hole for the male plug to be inserted. A limit block is provided on the receiving hole, and the limit block is used to limit the removal of the male plug from the receiving hole.

[0004] After the male and female plugs are assembled, the wiring part needs to be inserted between the male plug and the bending part of the U-shaped bar. Since the U-shaped bar is directly bent and formed, the distance between the U-shaped bar and the male plug is difficult to change, so the staff needs to apply greater force to insert the wiring part. Summary of the invention

[0005] In order to improve the problem that the wiring portion is difficult to insert into the male plug, the present application provides a double-pressure terminal connector.

[0006] The present application provides a dual-pressure terminal connector, which adopts the following technical solution: A double-pressure terminal connector comprises a male plug and a female plug, the female plug is provided with a receiving hole for the male plug to be inserted, the male plug is provided with a connecting strip, the connecting strip is provided with a first limit strip and a second limit strip with elasticity, the first limit strip and the second limit strip are distributed along the insertion direction of the wiring part, the first limit strip and the second limit strip are both bent towards the direction of the male plug, and the wiring part is located between the bending point of the first limit strip and the male plug.

[0007] By adopting the above technical solution, the first limit bar and the second limit bar are both elastic. When the wiring part is inserted between the bend of the first limit bar and the male plug, the wiring part can drive the first limit bar to deform. At this time, the distance between the first limit bar and the male plug can be changed, and the first limit bar and the second limit bar are distributed along the insertion direction of the wiring part. The wiring part is easier to push the first limit bar to deform. Compared with the background technology, the force applied to the wiring part is smaller, so that the wiring part can be inserted into the male plug more easily; because the first limit bar and the second limit bar are distributed along the insertion direction of the wiring part, during the insertion of the wiring part, the wiring part first abuts the first limit bar, and then the wiring part abuts the second limit bar, so that the staff can feel the two-stage limit during the insertion of the wiring part, so that the wiring part is not easy to be pulled out of the male plug.

[0008] Optionally, a yielding strip is bent on the first limiting strip, and the distance between the yielding strip and the male plug gradually increases along the direction from the connecting strip to the first limiting strip.

[0009] By adopting the above technical solution, the distance between the give way strip and the male plug is gradually increased along the direction from the connecting strip to the first limiting strip. When the wiring part is inserted, the wiring part can abut against the give way strip, so that the wiring part drives the first limiting strip to deform through the give way strip, so that the first limiting strip can limit the wiring part, so that the first limiting strip can better adapt to the wiring part with larger thickness.

[0010] Optionally, a limiting block is bent on the second limiting strip, and the distance between the limiting block and the male plug gradually increases along the direction from the connecting strip to the second limiting strip. When the wiring part is inserted into the male plug, the wiring part first abuts against the first limiting strip and then against the second limiting strip.

[0011] By adopting the above technical solution, the distance between the limit block and the male plug gradually increases along the direction from the connecting strip to the second limit strip, and the wiring portion abuts against the bending part of the limit block and the second limit strip, so that the bending part of the second limit strip and the limit block is smoother, thereby reducing the wear of the wiring portion by the bending part of the second limit strip and the limit block.

[0012] Optionally, a protrusion is provided on the male plug, and the protrusion is located on the insertion path of the wiring portion. When the wiring portion abuts against the protrusion, the wiring portion abuts against the first limiting strip and the second limiting strip.

[0013] By adopting the above technical solution, the protrusion is located on the insertion path of the wiring part, so that the protrusion limits the further movement of the wiring part, thereby fixing the insertion position of the wiring part, making the connection between the wiring part and the male plug more stable.

[0014] Optionally, one side opening of the accommodating hole is an entrance for inserting the male plug, an elastic strip is provided on the inner wall of the accommodating hole, the elastic strip is bent toward the direction of the male plug, the elastic strip is located on the moving path of the male plug, and when the male plug is inserted into the accommodating hole, the male plug is located on the side of the elastic strip away from the entrance of the accommodating hole.

[0015] By adopting the above technical solution, when the male plug is inserted into the accommodating groove, the male plug drives the elastic strip to deform, so that the elastic strip does not limit the insertion of the male plug. When the male plug is inserted into place, the male plug does not abut the elastic strip. At this time, the elastic strip is elastically reset and is located on the moving path of the male plug. The humidified male plug is located on the side of the elastic strip away from the entrance of the accommodating hole, so that the elastic strip limits the movement of the male plug, thereby achieving the male plug being stably located in the female plug.

[0016] Optionally, the female plug is provided with an elastic fixing spring sheet, which is deformed in the direction of the first limiting strip; when the male plug is inserted into the accommodating hole, the fixing spring sheet drives the first limiting strip to deform in the direction of the male plug.

[0017] By adopting the above technical solution, the fixed spring piece is deformed in the direction of the first limit strip, so that the fixed spring piece drives the first limit strip to move, allowing the first limit strip to be deformed in the direction of the male plug, further strengthening the limiting effect of the first limit strip on the male plug, making it difficult for the male plug to detach from the first limit strip.

[0018] Optionally, a placement groove is provided on the female plug, a placement bar is detachably connected to the placement groove, and a placement spring block is provided on the placement bar; when the placement bar is located in the placement groove, the placement spring block drives the fixed spring sheet to abut against the first limit bar.

[0019] By adopting the above technical solution, the staff installs the placement bar in the placement slot, so that the placement bar drives the fixed spring piece to move through the placement spring block, so that the fixed spring piece increases the force of the first limit bar, so that the first limit bar can increase the limiting effect on the male plug; when the staff inserts the wrong wiring part into the male plug, the staff removes the placement bar from the placement slot, releases the force of the placement bar on the fixed spring piece, reduces the force of the fixed spring piece on the first limit bar, and the wiring part can be taken out of the first limit bar; through the installation or disassembly of the placement bar, the connector is in a locked state or a pre-fixed state.

[0020] Optionally, a U-shaped strip is provided on the female plug, one end of the U-shaped strip is located on the side of the fixed spring sheet facing the first limit strip, and the other end of the U-shaped strip is located on the side of the placement strip away from the fixed spring sheet; when the fixed spring sheet is deformed toward the first limit strip, the end of the U-shaped strip close to the first limit strip drives the other end of the U-shaped strip to abut against the placement strip.

[0021] By adopting the above technical solution, when the fixed spring piece is deformed in the direction of the first limit strip, the fixed spring piece drives one end of the U-shaped strip to move. At this time, the other end of the U-shaped strip also moves on the same side, so that the U-shaped strip can abut against the placement strip, making it difficult for the placement strip to move in the female plug due to the restriction of the U-shaped strip, making it difficult for the placement strip to detach from the placement groove, thereby further strengthening the mutual fixing effect between the placement strip and the female plug.

[0022] Optionally, a first stop strip is provided on the first limiting strip, and the distance between the first stop strip and the connecting strip gradually increases along the direction from the first limiting strip to the connecting strip; when the wiring portion abuts against the first limiting strip, the first stop strip can abut against the wiring portion.

[0023] By adopting the above technical solution, when the wiring part abuts against the first limit strip, the first limit strip is deformed in the direction away from the male plug, so that the first limit strip drives the first stop strip to deform in the direction of the male plug, and the force between the first stop strip and the wiring part is increased, making it difficult for the wiring part to separate from the first limit strip.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: 1. Both the first limit bar and the second limit bar are elastic. When the wiring part is inserted between the bend of the first limit bar and the male plug, the wiring part can drive the first limit bar to deform. At this time, the distance between the first limit bar and the male plug can be changed. Compared with the background technology, the force applied to the wiring part is smaller, so that the wiring part can be inserted into the male plug more easily; because the first limit bar and the second limit bar are distributed along the insertion direction of the wiring part, during the insertion of the wiring part, the wiring part first abuts the first limit bar, and then the wiring part abuts the second limit bar, so that the staff can feel the two-stage limit during the insertion of the wiring part, so that the wiring part is not easy to be pulled out of the male plug.

[0025] 2. When the fixed spring piece is deformed in the direction of the first limit strip, the fixed spring piece drives one end of the U-shaped strip to move. At this time, the other end of the U-shaped strip also moves to the same side, so that the U-shaped strip can abut the placement strip, making it difficult for the placement strip to move in the female plug due to the restriction of the U-shaped strip, making it difficult for the placement strip to detach from the placement groove, further strengthening the mutual fixing effect between the placement strip and the female plug.

[0028] The following is combined with Figure 1-6 This application is described in further detail.

[0029] Example 1 This embodiment discloses a dual-pressure terminal connector. Figure 1 A double-pressure terminal connector includes a male plug 1 and a female plug 2. The female plug 2 is provided with a receiving hole 21 for inserting the male plug 1. One side of the receiving hole 21 is an inlet, and the other side of the receiving hole 21 is an outlet. The inlet is for inserting the male plug 1 to realize the assembly of the male plug 1 and the female plug 2, and the outlet is for inserting the wiring part into the male plug 1 to realize the assembly of the wiring part and the male plug 1.

[0030] Reference Figure 1 and Figure 2 Two connecting plates 11 are integrally formed on the male plug 1, and the two connecting plates 11 are respectively located on both sides of the male plug 1. The two connecting plates 11 are arranged vertically with the male plug 1, and the wiring part is inserted between the two connecting plates 11.

[0031] Reference Figure 2 A connecting strip 12 is integrally formed on the connecting plate 11, and the connecting strip 12 extends toward the other connecting plate 11. A first limiting strip 13 and a second limiting strip 14 are integrally formed on the surface of the connecting strip 12, and the first limiting strip 13 and the second limiting strip 14 are respectively located on different sides of the connecting strip 12, and the first limiting strip 13 is located on a side of the second limiting strip 14 close to the outlet.

[0032] Reference Figure 2, the distance between the first limiting strip 13 and the male plug 1 gradually increases along the direction from the first limiting strip 13 to the second limiting strip 14. A clearance strip 131 is integrally formed on the first limiting strip 13, and the distance between the clearance strip 131 and the male plug 1 gradually decreases along the direction from the first limiting strip 13 to the second limiting strip 14, and the clearance strip 131 is located on the side of the first limiting strip 13 away from the connecting strip 12. When the wiring portion is inserted into the male plug 1, the wiring portion abuts against the bend of the first limiting strip 13 and the clearance strip 131.

[0033] Reference Figure 2 , the distance between the second limiting strip 14 and the male plug 1 gradually decreases along the direction from the first limiting strip 13 to the second limiting strip 14. A limiting block 141 is integrally formed on the second limiting strip 14, and the distance between the limiting block 141 and the male plug 1 gradually increases along the direction from the first limiting strip 13 to the second limiting strip 14, and the limiting block 141 is located on the side of the second limiting strip 14 away from the connecting strip 12. When the wiring portion is inserted into the male plug 1, the wiring portion abuts against the bending portion of the second limiting strip 14 and the limiting block 141.

[0034] Reference Figure 1 and Figure 3 Two elastic strips 22 are fixedly connected to the hole wall of the receiving hole 21. The elastic strips 22 have elastic deformation ability. The elastic strips 22 are deformed in the direction of the male plug 1, and the two elastic strips 22 are located on the path of the male plug 1 as a whole. Two stop blocks 23 are fixedly connected to the hole wall of the receiving hole 21. The two stop blocks 23 are located at the exit of the receiving hole 21. When the male plug 1 abuts the stop blocks 23, the stop blocks 23 limit the male plug 1 from separating from the female plug 2 from the exit. At this time, the elastic strip 22 is reset. The elastic strip 22 is located on the side of the connecting strip 12 close to the entrance. The elastic strip 22 limits the male plug 1 from separating from the female plug 2 from the entrance.

[0035] Reference Figure 1 and Figure 3 When the male plug 1 is inserted into the female plug 2 from the entrance, the connecting strip 12 drives the elastic strip 22 to move, causing the elastic strip 22 to deform without restricting the movement of the male plug 1 until the male plug 1 abuts against the stop block 23. At this time, the elastic strip 22 is reset, and the elastic strip 22 restricts the movement of the connecting strip 12, so that the male plug 1 is fixed in the female plug 2.

[0036] Reference Figure 3 , a protrusion 24 is stamped on the male plug 1, and the protrusion 24 is located on the insertion path of the wiring part. When the wiring part is inserted into the male plug 1, the wiring part abuts the first limiting strip 13 and the second limiting strip 14 until the wiring part abuts the protrusion 24, thereby realizing the assembly of the wiring part and the male plug 1. A convex strip 241 is stamped on the male plug 1, and the protrusion 241 protrudes toward the direction of the connecting strip 12. When the wiring part abuts the protrusion 241, the wiring part can abut the first limiting strip 13.

[0037] The implementation principle of Example 1 is as follows: the staff first inserts the male plug 1 into the accommodating hole 21, allowing the connecting strip 12 to drive the elastic strip 22 to deform until the male plug 1 abuts against the stop block 23. At this time, the elastic strip 22 is reset, and the elastic strip 22 limits the movement of the male plug 1. Then the staff inserts the wiring part, allowing the wiring part to abut against the first limiting strip 13, the second limiting strip 14, the convex strip 241 and the convex block 24, so as to achieve mutual fixation of the wiring part and the male plug 1.

[0038] Example 2 Reference Figure 4 and Figure 5 The difference between this embodiment and the first embodiment is that two fixing springs 25 are fixedly connected to the female plug 2, and the fixing springs 25 have elastic deformation capability. The fixing springs 25 are deformed toward the male plug 1, and the fixing springs 25 can abut against the bending of the first limit strip 13 and the yield strip 131.

[0039] Reference Figure 6 The surface of the female plug 2 where the outlet is provided is provided with a placement groove 26 connected to the receiving hole 21, and a placement bar 261 is detachably connected in the placement groove 26, and a placement spring block 262 is fixedly connected to the surface of the placement bar 261, and the placement spring block 262 has elastic deformation capability. When the placement bar 261 is installed in the placement groove 26, the placement spring block 262 abuts against the fixed spring sheet 25, and at this time, the placement bar 261 drives the fixed spring sheet 25 to deform toward the direction of the male plug 1 through the placement spring block 262, so that the first limit bar 13 abuts against the wiring part, thereby improving the connection strength between the first limit bar 13 and the wiring part.

[0040] Reference Figure 6 The female plug 2 is provided with an operation hole 27 connected to the placement groove 26, and there are two operation holes 27. A U-shaped bar 28 is fixedly connected to the female plug 2, and the U-shaped bar 28 has elastic deformation capability. A groove 263 for inserting the U-shaped bar 28 is provided on the surface of the placement bar 261 away from the fixed spring sheet 25, and the groove 263 penetrates to the side of the placement bar 261. One end of the U-shaped bar 28 is located on the side of the placement bar 261 close to the first limiting bar 13, and the other end of the U-shaped bar 28 is located in the groove 263.

[0041] Reference Figure 6When the placement bar 261 is inserted into the placement groove 26, the placement spring block 262 drives the fixed spring piece 25 to deform toward the male plug 1. At this time, the fixed spring piece 25 drives the end of the U-shaped bar 28 close to the male plug 1 to tilt toward the male plug 1, and the other end of the U-shaped bar 28 away from the male plug 1 tilts toward the male plug 1. Since the U-shaped bar 28 is inserted into the groove 263, the U-shaped bar 28 drives the placement bar 261 to abut against the male plug 1, so that the placement bar 261 can be stably located in the placement groove 26. The staff drives the U-shaped bar 28 to move through the operating hole 27 to achieve the U-shaped bar 28 to disengage from the groove 263, so that the placement bar 261 is taken out of the placement groove 26.

[0042] Reference Figure 5 and Figure 6 The first stop bar 15 is integrally formed on the first limit bar 13, and the distance between the first stop bar 15 and the male plug 1 gradually decreases along the direction from the first limit bar 13 to the connecting bar 12. When the wiring part is inserted into the male plug 1, the wiring part drives the first limit bar 13 to deform in the direction away from the male plug 1, and the first limit bar 13 drives the first stop bar 15 to deform in the direction close to the male plug 1, thereby strengthening the force of the first stop bar 15 on the wiring part, so that the wiring part can abut the first stop bar 15 more stably, and at this time, the deformation degree of the first stop bar 15 is greater than the deformation degree of the second limit bar 14.

[0043] The implementation principle of Example 2 is as follows: the staff first inserts the wiring part so that the wiring part abuts the first limit strip 13, the second limit strip 14 and the first stop strip 15, and then the staff slides the placement strip 261 to insert the U-shaped strip 28 into the groove 263, so that the U-shaped strip 28 limits the movement of the placement strip 261 in the placement groove 26, and the placement spring block 262 drives the placement spring sheet to abut the first limit strip 13, thereby strengthening the limiting effect of the first limit strip 13 on the wiring part.
