Detailed Description

The following description is provided for illustrative purposes, and other advantages and features of the present invention will become apparent to those skilled in the art from the following detailed description.

Please refer to fig. 1-2. It should be understood that in the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate the position or positional relationship based on the position or positional relationship shown in the drawings, or the position or positional relationship that the product of the present invention is usually placed when in use, and are only for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the device or element to which the term refers must have a specific position, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," "third," and the like are used solely to distinguish one from another and are not to be construed as indicating or implying relative importance. The terms "horizontal", "vertical", "overhang" and the like do not imply that the components are required to be absolutely horizontal or overhang, but may be slightly inclined. For example, "horizontal" merely means that the direction is more horizontal than "vertical" and does not mean that the structure must be perfectly horizontal, but may be slightly inclined.

In the description of the present invention, it should be further noted that, unless otherwise explicitly stated or limited, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly and may include, for example, a fixed connection, a detachable connection, an integral connection, a mechanical connection, an electrical connection, a direct connection, an indirect connection via an intermediate medium, and a connection between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Example (b):

among the prior art, the terminal of most board end connector all is in unsettled state, and the product is when clapping the board, if the hole site does not have very right, perhaps terminal position degree is poor a little and all can lead to the connector to contract the needle when clapping the board, causes to clap the board harmfully, influences the product function.

As shown in fig. 1, for the utility model provides a pair of prevent moving back faller end connector, including connector body 1 and L type PIN needle 2, L type PIN needle 2 includes grafting end 3 and the stitch end 4 that mutually perpendicular set up. The inserting end 3 is inserted into the connector body 1, and the pin end 4 is inserted onto a circuit board (not shown). The problem of terminal pin shrinkage caused by deviation of hole positions and terminal position degrees when the board end connector and a circuit board are subjected to board beating assembly is solved. A first retaining mechanism for preventing the pin end from moving up and down is formed between the pin end 4 and the connector body 1. Specifically, the first stopping mechanism comprises a first clamping block 6 arranged on the pin end and a first clamping groove 7 arranged on the connector body 1, and the first clamping block 6 is clamped in the first clamping groove 7 to form vertical stopping.

As shown in fig. 2, is a schematic structural diagram of the L-shaped PIN of the present invention. Therefore, a second retaining mechanism for preventing the plug end from moving back and forth is formed between the plug end 3 of the L-shaped PIN needle 2 and the connector body 1. Specifically, the second stopping structure includes a second fixture block 8 disposed on the insertion end and a second clamping groove (not shown) disposed in the connector body, and the second fixture block 8 is clamped in the second clamping groove to form a front and rear stopping.

Furthermore, a transition part 5 which is obliquely arranged is arranged between the inserting end 3 and the pin end 4, so that the space utilization rate is improved, and the overall structural strength is improved.

In addition, the L-shaped PIN 2 can be a square PIN or a round PIN.

The principle is as follows:

a first backstop mechanism for stopping up and down is formed between the PIN end 4 of the L-shaped PIN PIN 2 and the connector body 1, the PIN shrinkage problem caused by position degree deviation of hole sites and terminals in the board beating process is avoided, and the reject ratio of products in the assembling process is reduced.

Therefore, the utility model has the advantages of it is following:

the utility model provides a prevent back faller end connector, the first stopping mechanism of stopping from top to bottom forms between L type PIN stitch end and the connector body, avoids beating the board in-process because hole site and terminal position degree deviation cause the shortening needle phenomenon, has improved product assembly yield.
