[0027] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.

[0028] Please refer to Figures 1 to 12 , a connector, comprising a female part;

[0029] The female component comprises a shell and a top block;

[0030] The housing is used to be installed in a mounting groove of a piece to be assembled;

[0031] The top block is movably arranged at one end of the shell, so that the top block can move toward the inside of the shell after contacting the bottom of the installation groove, so as to increase the volume of the shell, thereby achieving interference fit between the shell and the piece to be spliced.

[0032] From the above description, it can be seen that the beneficial effects of the present invention are: the present invention provides a connector, the mother part of the connector uses the top block to make the mother part and the part to be spliced ​​interfere with each other, so as to achieve a reliable connection and fastening effect. In addition, the device is easy to install, and the mother part can expand its volume by itself during the installation process through the movement of the top block, without the need for adjustment; since the mother part is fixed by the connector expanding by itself to achieve the fixing effect, and is set in the installation groove, it has better invisibility than the traditional three-in-one connector, and can better meet people's requirements for the aesthetics of furniture; the connector provided above can achieve convenient and reliable installation while ensuring beauty.

[0033] Further, it also includes the first public item;

[0034] The other end of the housing is provided with a slot adapted to the head of the first male component;

[0035] The first male component is used to be installed on another component to be spliced;

[0036] The fixed splicing of two pieces to be spliced ​​is achieved by snapping the head of the first male piece into the snapping groove on the shell.

[0037] From the above description, it can be seen that the two pieces to be spliced ​​are fixedly spliced ​​by using the cooperation of the male parts and the female parts. The splicing method is simple and has strong applicability. The male parts and the female parts can be made into standard components and used in various types of furniture.

[0038] Further, the top block includes a body;

[0039] The body is elliptical in shape.

[0040] It can be seen from the above description that, as the top block moves into the shell, the elliptical body gradually expands the volume of the shell, thereby achieving an interference fit between the shell and the piece to be spliced.

[0041] Furthermore, the top block also includes a limiting end and a contact end;

[0042] The limiting end is fixedly arranged at one end of the body portion, and is used to prevent the top block from escaping from the shell;

[0043] The contact end is fixedly arranged at the other end of the body.

[0044] It can be seen from the above description that the provision of the contact end can increase the contact area between the top block and the piece to be spliced, and reduce the pressure of the top block on the piece to be spliced.

[0045] Furthermore, one end of the shell is provided with a clearance cavity required for the movement of the top block;

[0046] The opposite sides of the relinquishing cavity are provided with openings.

[0047] It can be seen from the above description that the provision of the opening can improve the deformation capacity of the shell. When the top block squeezes the shell, the shell can be better expanded and the interference fit effect is better.

[0048] Further, it also includes multiple rows of anti-skid teeth;

[0049] The anti-slip teeth are arranged on the surface of the housing;

[0050] The side surface of the anti-slip teeth facing the top block is an inclined surface, and the side surface of the anti-slip teeth away from the top block forms a preset angle with the moving direction of the top block.

[0051] It can be seen from the above description that the provision of the anti-slip teeth can effectively prevent the mother component from being separated from the component to be assembled, thereby improving the tightness of the connection between the mother component and the component to be assembled.

[0052] Furthermore, the first male part has an end away from the head portion and is provided with an external thread for being screwed onto another part to be spliced;

[0053] The head is provided with a recess for the edge of the card slot to be embedded.

[0054] It can be seen from the above description that the provision of the clearance groove can make the clamping connection between the female component and the male component more reliable.

[0055] Furthermore, the card slot is provided with a slideway for the head of the first male component to slide;

[0056] The size of the middle part of the slot opening is larger than the size of the head of the first male component;

[0057] The size of the head of the first male component is smaller than the sizes of the two ends of the slot.

[0058] From the above description, it can be seen that the size of the middle of the slot is larger than the size of the two ends of the slot, and the head of the male part is inserted from the middle of the slot and slides toward the two ends to achieve the male part and the female part being connected. This connection method is simple and reliable, and the assembly is convenient and efficient.

[0059] Further, it also includes a second public item;

[0060] An end of the first male component away from the head is provided with an internal thread;

[0061] An end of the second male component away from the head thereof is provided with an external thread matched with the internal thread.

[0062] From the above description, it can be seen that when it is necessary to splice and fix a piece on two sides of a piece respectively, the second male piece is screwed to the other end of the first male piece, which can effectively solve the problem that the two male pieces cannot be fixed when the thickness of the piece to be spliced ​​is small.

[0063] Further, the top block includes two;

[0064] The two top blocks are symmetrically arranged at one end of the shell.

[0065] It can be seen from the above description that the two top blocks are symmetrically arranged on the shell, so that the shell can be subjected to more uniform force when expanding, and the contact between the shell and the parts to be spliced ​​is tighter and more reliable.

[0066] The above-mentioned connector can be used in any scenario where splicing is required. The pieces to be spliced ​​can be wood boards, plastics, steel, etc. The following description is based on the application scenario that the pieces to be spliced ​​are wood boards:

[0070] The top block 12 is movably arranged at one end of the shell 11, so that the top block 12 can move toward the inside of the shell 11 after contacting the bottom of the installation groove, so as to increase the volume of the shell 11, thereby achieving interference fit between the shell 11 and the wooden board to be spliced.

[0071] The shell 11 can be formed by split casting and then spliced ​​together; specifically, a positioning pin hole and a positioning pin are left on the split-molded shell, and the splicing and assembly of the shell is achieved through the cooperation of the positioning pin and the positioning pin hole.
