Description

Technical Field

[0001] The present application relates to the technical field of connectors, and in particular to an anti-deformation fixed end structure and a floating connector with the structure. Background Art

[0002] A floating connector is a connector with a floating function on the assembly interface. It can compensate for misalignment errors within a certain offset range and achieve precise connection. A floating connector consists of a floating end and a fixed end, where the floating end can move within a specified range to accommodate assembly errors.

[0003] The fixed end and the floating end of the floating connector both have evenly spaced and matched pins. The pins in the fixed end are usually fixedly assembled inside the fixed end shell by glue punching. When the pins to be assembled inside the fixed end shell are too long, the pins are easily skewed during the glue punching assembly process, making the pins in the fixed end mismatched with the pins in the floating end, thereby affecting the connection stability of the fixed end and the floating end. This problem needs to be solved urgently. Summary of the invention

[0036] The following is combined with Figure 1-7 This application is described in further detail.

[0037] The present application embodiment discloses an anti-deformation fixed end structure, referring to Figure 1 and Figure 2 , comprising a housing 1 and a plurality of pin needles 2, the housing 1 being arranged in a long strip frame shape, the plurality of pin needles 2 being evenly spaced and arranged inside the housing 1 along the length direction of the housing 1, and the pin needles 2 being arranged in two rows. It should be noted that a connection hole 5 is provided at one end in the width direction of the housing 1 so that the anti-deformation fixed end structure can be connected to the floating end 7. It is worth mentioning that the width of the middle position of the connection hole 5 in the length direction is greater than the width of the two end positions thereof, so as to avoid the pin needle 2 in the fixed end and the pin needle 2 in the floating end 7 when they are in contact and connected, and it is difficult to cause interference.

[0038] Reference Figure 2 and Figure 3, a mounting seat 6 is integrally formed in the middle position of the shell 1 along its length direction, and a plurality of pin needles 2 are fixedly arranged on the mounting seat 6. The mounting seat 6 supports the plurality of pin needles 2, and there is a containing space between the pin needles 2 and the inner side wall of the shell 1, so that the components of the floating end 7 can be inserted into the containing space and connected with the fixed end. It should be noted that there is a containing space between the side walls at both ends of the mounting seat 6 and the inner side wall of the shell 1, and the containing space between the side walls at both ends of the mounting seat 6 and the inner side wall of the shell 1 is connected to the containing space between the pin needles 2 and the inner side wall of the shell 1. Referring to Figure 6 and Figure 7 , so that the floating end 7 is inserted into the component of the accommodating space to wrap the mounting seat 6, so as to improve the stability of the connection between the fixed end and the floating end 7.

[0039] Reference Figure 3 The two ends of the connecting hole 5 in the length direction are chamfered, that is, the end of the hole wall of the connecting hole 5 is set with an outward-expanded bevel to facilitate the connection operation between the fixed end and the floating end 7. At the same time, the end of the mounting seat 6 is chamfered. Different from the inner chamfer of the connecting hole 5, the chamfer on the mounting seat 6 is set as an outer chamfer to further improve the convenience of the connection operation between the fixed end and the floating end 7.

[0040] Reference Figure 3 The inner side wall of the housing 1 is provided with a plurality of limit blocks 3 for limiting the position of the pin needle 2. The plurality of limit blocks 3 are arranged along the length direction of the housing 1. Figure 4 and Figure 5 The limit block 3 is integrally formed on the side wall of the mounting seat 6, and the limit block 3 and the pin needle 2 are arranged at a cross interval. Each pin needle 2 is located between two adjacent limit blocks 3, so that the two adjacent limit blocks 3 limit the pin needle 2 located therebetween, and the pin needle 2 is difficult to shake left and right and become skewed during the glue punching assembly process, which is beneficial to improving the assembly stability of the pin needle 2 in the fixed end, thereby helping to improve the connection stability between the fixed end and the floating end 7 in the floating connector.

[0041] Reference Figure 3 The inner wall of the housing 1 is provided with a limiting groove 4 along the length direction of the pin 2. Figure 4 and Figure 5The limiting groove 4 is provided on the side wall of the mounting seat 6. The number of the limiting grooves 4 is set to be the same as the number of the pin needles 2, and a plurality of limiting grooves 4 are arranged along the length direction of the housing 1. One pin needle 2 is correspondingly accommodated in one limiting groove 4. It should be noted that when the pin needle 2 is embedded in the limiting groove 4, the side surface of the pin needle 2 is flush with the side surface of the mounting seat 6. When the pin needle 2 is too long, the limiting groove 4 limits the pin needle 2 as a whole, which is conducive to further improving the assembly stability of the pin needle 2, thereby further improving the connection stability between the fixed end and the floating end 7 in the floating connector.

[0042] Reference Figure 5 and Figure 6 The limiting groove 4 is arranged with both ends connected, so that when the fixed end and the floating end 7 are connected, the pin needle 2 in the fixed end and the pin needle 2 in the floating end 7 are connected.

Figure 6 and Figure 7 , including the above-mentioned anti-deformation fixed end structure, and also including a floating end 7, the floating end 7 is adaptively connected to the anti-deformation fixed end structure. It should be noted that the independent inner and outer plastic bodies of the floating end 7 are connected through elastic terminals, allowing assembly deviation in the X, Y, and Z axis directions to achieve accurate connection with the fixed end.

[0045] The implementation principle of an anti-deformation fixed end structure and a floating connector with the structure in the embodiment of the present application is as follows: when the pin needle 2 is too long, the pin needle 2 is embedded in the limiting groove 4, and the limiting groove 4 limits the pin needle 2 as a whole, so that the pin needle 2 is difficult to shake during the glue punching assembly process, which is beneficial to improving the assembly stability of the pin needle 2. At the same time, two adjacent limiting blocks 3 limit the pin needle 2 located therebetween, and the pin needle 2 is difficult to tilt during the glue punching assembly process, which is beneficial to improving the assembly stability of the pin needle 2 in the fixed end, thereby facilitating improving the connection stability between the fixed end and the floating end 7 in the floating connector. The setting of the inner chamfer of the connecting hole 5 and the setting of the outer chamfer of the mounting seat 6 facilitate the connection operation between the fixed end and the floating end 7, thereby facilitating improving the production quality and use quality of the floating connector.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
