Referring to FIG. 1, an embodiment of the present utility model provides a small-sized connector convenient for dismounting and mounting, the connector being inserted and received in a female socket 2 of a PCB board 1, comprising:

• • a connector housing 3 inserted and received in the female socket 2;
  • two elastic clamping plates 4, wherein the two elastic clamping plates 4 are symmetrically mounted on both sides of the connector housing 3, first ends of the two elastic clamping plates 4 are each provided with a clamping hole 41, and the female socket 2 is provided with a clamping boss 21 clamped with the clamping hole 41; and
  • a pull strap 5, wherein both ends of the pull strap 5 are respectively connected to second ends of the two elastic clamping plates 4, and the pull strap 5 is used to pull the second ends of the two elastic clamping plates 4 to separate the clamping holes 41 at the first ends of the two elastic clamping plates 4 from the clamping bosses 21 of the female socket 2.

It should be noted that, it is common to connect a plurality of connectors on the PCB board 1, and two adjacent connectors are closely arranged, such that when a connector is to be dismounted, the operating space for both hands of an operator is limited, and the connector can only be dismounted by pulling a wire connected to the connector, which may easily cause damage to the connector; in this embodiment, the structure of the existing connector is improved by symmetrically mounting two elastic clamping plates 4 outside the connector, connecting the clamping hole 41 at the first end of the elastic clamping plate 4 to the clamping boss 21 on the female socket 2, and meanwhile, connecting the second ends of the two elastic clamping plates 4 through a pull strap 5, and extending the pull strap 5 outside the connector, such that when dismounting the connector, it is only required to pull the pull strap 5 with hands, to rotate the second ends of the two elastic clamping plates 4 relative to each other, and therefore to allow the first ends of the two elastic clamping plates 4 to be opened relative to each other, such that the clamping of the clamping hole 41 and the clamping boss 21 is released, and the connector can be quickly pulled out, which solves the problems of small mounting space and inconvenience of manual pulling and inserting in the existing connector.

Further, referring to FIG. 3, the elastic clamping plate 4 comprises a clamping plate body 42, two connecting parts 43 connected to the connector housing 3 are symmetrically arranged on both sides of the clamping plate body 42, the two connecting parts 43 are each connected to the clamping plate body 42 through a connecting arm 44, and the two connecting arms 44 are symmetrically arranged in a splayed shape.

In this embodiment, the structure of the elastic clamping plate 4 is further optimized. The clamping plate body 42 is provided as a cuboid-shaped structure in which one end is provided with the clamping hole 41 to be clamped with the clamping boss 21 on the female socket 2, and the other end is connected to the pull strap 5, both sides of a middle part of the clamping plate body 42 are each provided with a connecting arm 44, the two connecting arms 44 extend in a splayed shape and are provided with a connecting part 43 for being connected to the connector housing 3 at one end, such that since the connecting parts 43 are fixed, both ends of the clamping plate body 42 can be rotated under the elastic deformation of the connecting arms 44. Specifically, when an operator pulls the pull strap 5, the second end of the clamping plate body 42 is forced to rotate towards one side in proximity to the connector housing 3, and at this point, the connecting arm 44 is equivalent to a rotating shaft for rotating the clamping plate body 42 based on the deformation of the rotating shaft, and in this way, the first end of the clamping plate body 42 will be rotated in a direction away from the connector housing 3 (and therefore, the clamping boss 21), such that the clamping force of the clamping hole and the clamping boss 21 can be released, and the connector can be easily pulled out from the female socket 2.

Further, the connecting part 43 is provided as a rectangular plate structure, the connector housing 3 is provided with a sliding groove 31 for mounting the connecting part 43, a side wall of the sliding groove 31 is provided with a first hole 32 communicated with the sliding groove 31, the connecting part 43 is provided with a second hole 45 docked with the first hole 32, and the first hole 32 and the second hole 45 are fixed by inserting and receiving a fixing pin 33.

In this embodiment, the elastic clamping plate 4 is detachably mounted on the connector housing 3, to facilitate the replacement of the elastic clamping plate 4 after being used for a long time. Specifically, the elastic clamping plate 4 is slidably inserted into the sliding groove 31 of the connector housing 3 through the connecting part 43, and when the second hole 45 of the connecting part 43 corresponds to the first hole 32 on the side wall of the sliding groove 31, the fixing pin 33 is inserted to limit the two holes, such that the elastic clamping plate 4 can be stably mounted on the connector housing 3.

Further, the clamping plate body 42, the connecting part 43 and the connecting arm 44 are provided as an integrated structure, and the elastic clamping plate 4 takes the form of an integrated structure, which realizes a convenient manufacturing, a simplified manufacturing process, a reduced manufacturing cost, and a greatly improved production efficiency.

Further, the first end of the elastic clamping plate 4 is provided with an inclined guide surface 46. In this embodiment, the inclined guide surface 46 is arranged in proximity to one side that is of the elastic clamping plate 4 and that is in proximity to the clamping boss 21. During the process of clamping the elastic clamping plate 4 with the clamping boss 21, the inclined guide surface 46 first contacts the clamping boss 21, and during the process of pressing the elastic clamping plate 4 downwards, that is, inserting the connector into the female socket 2, the inclined guide surface prevents the elastic clamping plate 4 from being stuck with the clamping boss 21 and thus causing the connector to fail to be inserted into the female socket 2 smoothly.

Further, referring to FIG. 4, the clamping boss 21 comprises an arc-shaped guide surface 22 for guiding the first end of the elastic clamping plate 4, and a clamping surface 23 for clamping with the clamping hole 41. In this embodiment, the arc-shaped guide surface corresponds to the inclined guide surface 46 of the elastic clamping plate 4, and the two surfaces function to guide each other, and therefore guide the elastic clamping plate 4, such that the connector is facilitated to be inserted into the female socket 2. When the connector is inserted into the female socket 2 in place, the clamping surface 23 of the clamping boss 21 is clamped with the clamping hole 41 of the elastic clamping plate 4, to effectively limit the connector and the female socket 2.

Further, a plurality of metal partition plates 24 are mounted on an inner side of the female socket 2, the metal partition plates 24 form a plurality of accommodating spaces for accommodating elastic pieces of the connector respectively, and the metal partition plates 24 are connected to ground wires of the connector. It should be noted that, after the connector is inserted into the female socket 2, the accommodating spaces of the metal partition plates 24 provide an independent space for each group of the elastic pieces of the connector, and the metal partition plates 24 are connected to the ground wires of the connector, which can form an independent closed space for each group of the elastic pieces after the connector is powered on, such that signal dispersion is effectively prevented, and signal interference is avoided between two adjacent groups of the elastic pieces.

Further, the metal partition plate 24 is provided as a copper plate or a stainless steel plate, to facilitate connection and conduction with the ground wire and further improve the structural stability.

Further, the pull strap 5 is connected to a T-shaped handle 51 to facilitate the operation of an operator. It is only required to hold the T-shaped handle 51 to pull the pull strap 5 to pull the connector out.

The above mentioned contents are only optional embodiments of the present utility model and are not intended to limit the patent scope of the present utility model, and under the utility model concept of the present utility model, the equivalent structural transformations made by using the contents of the specification and the drawings of the present utility model, or direct/indirect applications to other related technical fields, are all included in the patent protection scope of the present utility model.
