Description

Technical Field

[0001] The utility model relates to the field of electrical connectors, and more specifically to a fast-assembled connector housing. Background Art

[0002] Electrical connectors are widely used as signal transmission connection devices in the fields of electronics and communications; especially in radio frequency signal transmission, the use of connectors is very common; the structures and forms of connectors are varied, among which there is a threaded connector, which is designed with a male head, a female head and a shell, one end of the shell is rotatably positioned and connected to the male head (or female head), and the other end of the shell is threadedly connected to the female head (or male head). During manufacturing, one end of the shell is clamped on one end of the male head (or female head) so that the shell forms a rotationally positioned connection relative to the male head (or female head), that is, the shell can rotate relative to the male head (or female head), but the two are axially positioned and connected and cannot fall off. When in use, the male head is docked with the female head, and the shell is rotated, and connected through the thread between the shell and the female head (or male head). However, in the actual manufacturing process, how to achieve rapid assembly between the two not only affects production efficiency, but is also closely related to product quality. Therefore, how to design a connector shell that can meet quality requirements and achieve rapid assembly is the subject of research of this utility model.

[0003] For example, the Chinese utility model with application number 201922046576576.2 proposes a quickly assembled connector shell. The patent first aligns the connector shell with the connector body, and then presses the connector shell until the cutout groove is stretched and deformed by the outer chamfer of the connector body, and then continues to press. When the flange of the connector shell enters the annular groove of the connector body, the six-piece elastic expansion structure will naturally rebound and reset, and the connector shell and the connector body will be clamped together. However, in order to remove the connector body from the connector shell, the patent can only manually pry open the six-piece elastic expansion structure at the cutout groove, which is more laborious. In addition, the elasticity of the six-piece elastic expansion structure will decrease after being used many times, which will cause the effect of the connector shell fixing the connector body to deteriorate.

[0004] Therefore, the utility model provides a connector housing for quick assembly. Utility Model Content

[0005] The utility model aims to solve the technical problems raised by the above-mentioned background technology and provides a quick-assembled connector shell. When in use, the connector body can be fixedly installed in the connector shell by a clamping block and a first limiting groove, and the connector body can be easily removed from the connector shell by providing a reset block and a first limiting column.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: comprising a connector shell and a connector body, the connector body is embedded and installed in the connector shell, two first limit columns are connected inside the connector shell, the front and rear ends of the first limit columns are connected to torsion springs, the front and rear surfaces of the connector shell are provided with a plurality of first limit grooves, the left and right sides of the first limit grooves are provided with second limit grooves, a reset block is installed in the first limit groove, the left and right sides of the reset block are connected to the limit blocks, the front and rear surfaces of the connector body are connected with a plurality of card blocks, the upper and lower ends of the left side of the card block are provided with fixing plates, the left end of the card block is connected through a connecting column, the upper and lower ends of the rear side of the card block are connected to the connecting block, the surface of the connecting block is connected to the second limit column, the right side of the rear end of the card block is connected to a compression spring, and the connector body is provided with a plurality of inner cavities, and the inner cavities are provided with a third limit groove.

[0007] A further preferred solution: the cross-section of the first limit column is elliptical, and the front and rear ends of the first limit column are connected to extension columns. The torsion spring is sleeved on the surface of the extension column, and one end of the torsion spring is fixedly connected to the connector housing, and the other end is fixedly connected to the first limit column, and the first limit column and the connector housing are rotatably connected.

[0008] A further preferred solution is that the reset block is embedded in the first limiting groove, and the limiting block is located in the second limiting groove.

[0009] A further preferred solution is that the clamping block is located between two fixed plates, and the connecting column passes through the clamping block and is rotatably connected to the fixed plates.

[0010] A further preferred solution is that the blocking block is located above the inner cavity, and the second limiting column is located in the third limiting groove.

[0011] A further preferred solution is that the front end of the compression spring is fixedly connected to the rear end of the clamping block, and the rear end of the compression spring is fixedly connected to the inner wall of the inner cavity.

[0012] A further preferred solution is that the right side wall of the inner cavity and the third limiting groove are both arc-shaped, and the radius lengths of the two arcs are the same and larger than the length of the blocking block.

[0013] Beneficial effects:

[0014] 1. The first limiting column and the reset block can be provided to facilitate the removal of the connector body from the connector housing. The reset block can move the buckle into the inner cavity, thereby disengaging from the first limiting groove.

[0015] 2. The card block and the first limiting groove can be provided to fix the connector body in the connector housing. After the connector body is inserted into the connector housing, the card block will move to the first limiting groove, and the card block will move into the first limiting groove through the rebound force of the compression spring, so that the connector body is fixed in the connector housing;

[0016] 3. By providing a second limit column and a third limit groove, the card block can be prevented from being dislocated when it is bounced up by the rebound force of the compression spring. When the card block rebounds due to the rebound force of the compression spring, the second limit column will move along the side wall of the third limit groove. When the second limit column moves to the top of the third limit groove, the second limit column stops moving. At this time, the card block also stops moving due to the influence of the second limit column, thereby preventing the card block from being dislocated. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following will be combined with the attached embodiment of the present utility model Figure 1-Figure 6 , clearly and completely describe the technical solutions in the embodiments of the utility model.

[0025] See also Figure 1-6In the embodiment of the utility model, a quick-assembled connector shell comprises a connector shell 1 and a connector body 2, the connector body 2 is embedded and installed in the connector shell 1, two first limiting columns 4 are connected inside the connector shell 1, and the front and rear ends of the first limiting columns 4 are connected to torsion springs 6, the front and rear surfaces of the connector shell 1 are provided with a plurality of first limiting grooves 5, the left and right sides of the first limiting grooves 5 are provided with second limiting grooves 7, a reset block 3 is installed in the first limiting groove 5, and the left and right sides of the reset block 3 are connected to limiting blocks 8, the front and rear surfaces of the connector body 2 are connected with a plurality of card blocks 9, the upper and lower ends of the left side of the card block 9 are provided with fixing plates 10, the left end of the card block 9 is connected through a connecting column 16, the upper and lower ends of the rear side of the card block 9 are connected to a connecting block 12, the surface of the connecting block 12 is connected to a second limiting column 13, and the right side of the rear end of the card block 9 is connected to a compression spring 11, a plurality of inner cavities 15 are provided in the connector body 2, and a third limiting groove 14 is provided in the inner cavity 15, firstly, the connector body 2 is inserted from the opening of the connector shell 1, when the card block When 9 passes through the opening of the connector shell 1, the card block 9 is moved into the inner cavity 15 by the pressure of the front and rear side walls of the connector shell 1. When the left end of the connector body 2 contacts the first limiting column 4, the first limiting column 4 will be tilted and gradually fit the surface of the connector body 2. At the same time, the card block 9 also moves to the first limiting groove 5. At this time, the card block 9 loses the pressure of the two front side walls of the connector shell 1, and the compression spring 11 rebounds to reset the card block 9, thereby moving the card block 9 to the first limiting groove 5, and then the connector body 2 is fixedly installed in the connector shell 1; when the connector body 2 needs to be taken out of the connector shell 1, the staff presses the reset block 3 to move the reset block 3 into the connector shell 1, and the reset block 3 is used to make the card block 9 disengage from the first limiting groove 5. At this time, the torsion spring 6 will rebound and reset after being not restricted, thereby driving the first limiting column 4 to rotate along the surface of the connector body 2 to reset. When the first limiting column 4 rotates, it will move the connector body 2 to the right, thereby popping the connector body 2 out of the connector shell 1.

[0026] In the embodiment of the utility model, the cross-section of the first limit column 4 is elliptical, and the front and rear ends of the first limit column 4 are connected to extension columns. The torsion spring 6 is sleeved on the surface of the extension column, and one end of the torsion spring 6 is fixedly connected to the connector housing 1, and the other end is fixedly connected to the first limit column 4. The first limit column 4 and the connector housing 1 are rotatably connected, the reset block 3 is embedded in the first limit groove 5, and the limit block 8 is located in the second limit groove 7. The first limit column 4 and the reset block 3 can be easily removed from the connector housing 1.

[0027] During use, after the connector body 2 is inserted into the connector shell 1, the left end of the connector body 2 will cause the first limiting column 4 to tilt and then fit onto the surface of the connector body 2. At this time, the torsion spring 6 will also be compressed. When the connector body 2 needs to be taken out, the staff presses the reset block 3 and moves the reset block 3 into the connector shell 1. The reset block 3 causes the blocking block 9 to disengage from the first limiting groove 5. At this time, the torsion spring 6 will rebound and reset after being unrestricted, thereby driving the first limiting column 4 to rotate along the surface of the connector body 2 for reset. When the first limiting column 4 rotates, it will cause the connector body 2 to move to the right, thereby popping the connector body 2 out of the connector shell 1.

[0028] The block 9 is located between the two fixed plates 10, the connecting column 16 passes through the block 9 and is rotatably connected to the fixed plate 10, the block 9 is located above the inner cavity 15, the second limiting column 13 is located in the third limiting groove 14, the front end of the compression spring 11 is fixedly connected to the rear end of the block 9, and the rear end of the compression spring 11 is fixedly connected to the inner wall of the inner cavity 15. The block 9 and the first limiting groove 5 can fix the connector body 2 in the connector housing 1.

[0029] When in use, the connector body 2 is inserted from the opening of the connector shell 1. When the card block 9 passes through the opening of the connector shell 1, the card block 9 is subjected to the pressure of the front and rear side walls of the connector shell 1 and moves toward the inner cavity 15. At the same time, the compression spring 11 is compressed. When the card block 9 moves to the first limiting groove 5, the card block 9 loses the pressure of the two front side walls of the connector shell 1. At this time, the compression spring 11 rebounds, causing the card block 9 to reset, thereby moving the card block 9 to the first limiting groove 5, and then fixing the connector body 2 in the connector shell 1.

[0030] The right side wall of the inner cavity 15 and the third limiting groove 14 are both arc-shaped. The radius of the two arcs is the same and larger than the length of the block 9. The second limiting column 13 and the third limiting groove 14 can prevent the block 9 from being dislocated when it is bounced up by the rebound force of the compression spring 11.

[0031] During use, when the block 9 rebounds due to the rebound force of the compression spring 11, the block 9 will drive the connecting block 12 to move, and the connecting block 12 will drive the second limiting column 13 to move along the side wall of the third limiting groove 14. When the second limiting column 13 moves to the top of the third limiting groove 14, the second limiting column 13 stops moving. At this time, the block 9 also stops moving due to the influence of the second limiting column 13, thereby preventing the block 9 from dislocating.
