< example 1>

Hereinafter, the plug connector 100 according to the present embodiment will be described with reference to fig. 1 to 4B.

As shown in fig. 1 and 2, the plug connector 100 may include a base 110,

locking portions

120, 130, and a control mechanism 140.

The base 110 may be used to support the

locking portions

120, 130 and the control mechanism 140. While the base 110 is shown in fig. 1 and 2 as being formed in a "chevron" shape, the base 110 may be formed in other shapes, such as various suitable shapes, e.g., a rectangle, an oval, a trapezoid, or a "chevron" shape with one or more through-holes for receiving a cable. The base 110 may include a guide portion 111, and the guide portion 111 may be used to guide sliding of a movable portion 142 of a control mechanism 140 described in detail below. For example, the guide portion 111 may be a chute, a through hole, or the like.

Fig. 1 and 2 illustrate the inclusion of two

locking portions

120, 130, but the plug connector 100 may include only either one of the

locking portions

120, 130, or may further include one or more additional locking portions in addition to the

locking portions

120, 130. For example, one or more additional locking portions are arranged above and/or below the locking portion 120 and/or the locking portion 130 in a stacked manner in a direction perpendicular to the paper surface of fig. 1.

One end of the locking part 120 may be fixed to a first side of the base 110 and extend in a direction substantially perpendicular to the base 110, and the locking part 130 may be provided at a second side of the base 110 opposite to the first side symmetrically to the locking part 120 and extend in a direction substantially perpendicular to the base 110. Fig. 1 and 2 show the

locking parts

120 and 130 fixed to the first and second sides, respectively, by means of a snap connection, but the fixing may be performed by other means, such as adhesion, screw fitting, screw-hole connection, or the

locking parts

120 and 130 being integrally formed with the base 110. The structure and function of the locking part 130 may be the same as or similar to those of the locking part 120, and therefore, only the structure and function of the locking part 120 will be described in detail below.

As shown in fig. 3, the locking part 120 may include a drawn part 121 and an engaging part 122, the engaging part 122 may be located at the other end of the locking part 120 opposite to the one end fixed to the base 110 and protrude outward, and the other end of the locking part 120 may be elastically swingable around the fixed one end (i.e., the one end fixed to the first side of the base 110). The towed portion 121 may include a hole 123, and the hole 123 may be inserted with a column 143 included in the towing portion 141 of the control mechanism 140, which will be described in detail below.

The locking portion 120 may further include a retaining hole 124, and the retaining hole 124 may be located between the engaging portion 122 and the drawn portion 121, for example. The retention apertures 124 may be used to facilitate the retention of the plug connector 110 after insertion into a female socket (not shown).

Alternatively, the locking part 120 may further include a guide structure 125 at the other end opposite to the end fixed to the base 110, and the guide structure 125 may be used to guide the insertion of the plug connector 100. Preferably, the guide structure 125 may have a "V" shape. More preferably, the guide structure 125 may have a chamfer.

Alternatively, the locking part 120 may further include an elastic part 126, and the elastic part 126 may be located between the engaging part 122 and one end of the locking part 120 fixed to the base 110. The resilient portion 126 is preferably bendable to facilitate insertion and removal of the plug connector 100.

Preferably, the locking part 120 may be formed in a sheet shape as illustrated in fig. 1 and 2, but may be formed in other shapes such as a block shape. Further, preferably, all or part of the locking part 120 may be formed of an elastic material (such as plastic, rubber, etc.).

As shown in fig. 4A and 4B, the control mechanism 140 may include a drawing part 141 and a movable part 142. The control mechanism 140 is slidable in a direction substantially perpendicular to the base. The drawing part 141 may be engaged with the drawn part 121 of the locking part 120. The movable part 142 may be coupled to the traction part 141. As an example, the movable part 142 may be detachably fixed to the drawing part 141. As yet another example, the movable part 142 may be integrally formed with the drawing part 141. The pulling part 141 may include a cylinder 143, and the cylinder 143 may be inserted into the hole 123. The movable portion 142 may be slidably disposed on the base 110 with respect to the base 110.

In a case where the movable part 142 slides with respect to the base 110, the drawing part 141 moves, whereby the column 143 of the drawing part 141 takes the drawn part 142, so that at least a part of the locking part 120 (e.g., the holding hole 146 and a part near the drawn part 142) can elastically swing around one end fixed to the base 110. Thereby, for example, via the sliding of the movable portion 142 of the control mechanism 140 relative to the base 110, the magnitude of the elastic swinging of at least a part of the locking portion 120 can be controlled, thereby controlling the connection state between the plug connector 100 and a receptacle connector (not shown) that is normally a male-female pair with the plug connector 100. For example, if the movable portion 142 is slid from front to back (direction from left to right in fig. 1) with respect to the base 110, the column 143 of the pulling portion 141 moves backward, the pulled portion 142 also moves backward, and thereby, a portion of the locking portion 120 close to the engaging portion 122 elastically swings inward about one end fixed to the base 110, whereby the plug connector 100 can be inserted into the receptacle connector without being blocked, or the engaging portion 122 is caused to disengage from the receptacle connector so that the plug connector 100 is unlocked and disengaged from the receptacle connector; if the movable portion 142 is slid from back to front with respect to the base 110, the column 143 of the pulling portion 141 moves forward, moving the pulled portion 142 forward as well, so that a portion of the locking portion 120 close to the engaging portion 122 swings elastically outward about one end fixed to the base 110 to recover toward an original state of the locking portion 120 (i.e., a state when the locking portion 120 is not elastically deformed), whereby in a state where the plug connector 100 has been inserted into the receptacle connector, the engaging portion 122 may be caused to engage with the receptacle connector so that the plug connector 100 is locked to the receptacle connector.

Thus, according to plug connector 100 of embodiment 1, while ensuring a simple and reliable structure of plug connector 100, the connection state between plug connector 100 and the receptacle connector can be easily controlled by adjusting only the sliding movement of movable portion 142 with respect to base 110, thereby ensuring easy connection between plug connector 100 and the receptacle connector and saving the operation space.

< example 2>

Hereinafter, the locking portion 200 of the plug connector according to the present embodiment will be described with reference to fig. 5.

The structure of the plug connector according to the present embodiment is basically similar to the plug connector 100 in embodiment 1, except for a part of the structure of the locking portion 200. Hereinafter, only the structure of the lock portion 200 will be described, and descriptions of other parts of the plug connector according to the present embodiment will be omitted.

Similar to the locking part 120 of embodiment 1, as shown in fig. 5, the locking part 200 may include a drawn part 210 and an engaging part 220, the engaging part 220 being located at the other end of the locking part 200 opposite to the one end fixed to the base and protruding outward, the other end of the locking part 200 being elastically swingable around the fixed one end (i.e., the one end fixed to the first side of the base). Preferably, the locking part 200 may be formed in a sheet shape as shown in fig. 5, but may be formed in other shapes such as a block shape. Further, preferably, all or part of the locking part 200 may be formed of an elastic material (such as plastic, rubber, etc.). Alternatively, the locking part 200 may further include an elastic part 230, and the elastic part 230 is located between the engaging part 220 and one end of the locking part 200 fixed to the base. The elastic portion 230 is preferably bent to facilitate insertion and removal of the plug connector. Alternatively, the locking part 200 may further include a guide structure 240 at the other end opposite to the one end fixed to the base, and the guide structure 240 may be used to guide the insertion of the plug connector. Preferably, the guide structure 240 may have a "V" shape. More preferably, the guide structure 240 may have a chamfer. The locking portion 200 may also include a retaining aperture 250, such as between the snap feature 220 and the pulled feature 210, of the retaining aperture 250. The retention apertures 250 are used to facilitate the plug connector remaining secured after insertion into a female socket (not shown).

Instead of the hole 123 included in the drawn part 121 in embodiment 1, the drawn part 210 may include a groove 211 opened toward the other end of the locking part 200 including the guide structure 240. The traction part of the control mechanism comprises a cylinder that can be snapped into said groove, so that the traction part can bring the drawn part 210 of the locking part 200 when the movable part of the control mechanism slides relative to the base.

With the plug connector having the locking portion 200 of the present embodiment, a technical effect similar to that of embodiment 1 can be achieved.

< example 3>

Hereinafter, the locking portion 300 of the plug connector according to the present embodiment will be described with reference to fig. 6.

The structure of the plug connector according to the present embodiment is basically similar to that of the plug connector in embodiment 2, except for a part of the structure of the lock portion 300. Hereinafter, only the structure of the lock portion 300 will be described, and descriptions of other parts of the plug connector according to the present embodiment will be omitted.

Similar to the lock portion 200 of embodiment 2, as shown in fig. 5, the lock portion 300 may include a drawn portion 310 and an engaging portion 320, the engaging portion 320 being located at the other end of the lock portion 300 opposite to the end fixed to the base and protruding outward, the other end of the lock portion 300 being capable of elastically swinging around the fixed end (i.e., the end fixed to the first side of the base). Preferably, the locking part 300 may be formed in a sheet shape as shown in fig. 6, but may be formed in other shapes such as a block shape. Further, preferably, all or part of the locking part 300 may be formed of an elastic material (such as plastic, rubber, etc.). Alternatively, the locking part 300 may further include an elastic part 330, and the elastic part 330 is located between the engaging part 320 and one end of the locking part 200 fixed to the base. The elastic portion 330 is preferably bent to facilitate insertion and removal of the plug connector. Alternatively, the locking part 300 may further include a guide structure 340 at the other end opposite to the one end fixed to the base, and the guide structure 340 may be used to guide the insertion of the plug connector. Preferably, the guide structure 340 may have a "V" shape. More preferably, the guide structure 340 may have a chamfer. The drawn part 310 may include a groove 311 opened toward the other end of the locking part 300 including the guide structure 340. The traction part of the control mechanism may comprise a post that may snap into said groove, such that the traction part may bring the drawn part 310 of the locking part 300 when the movable part of the control mechanism slides relative to the base.

In contrast, the locking portion 220 may not include a retaining hole. As such, with respect to embodiments 1 and 2, the step of forming the holding hole can be omitted in the manufacturing process of the lock portion 300, whereby the process cost can be saved.

With the plug connector of the present embodiment having the locking portion 300, the technical effects similar to those of embodiments 1 and 2 can be achieved.

< example 4>

The connector device according to the present embodiment will be described below with reference to fig. 7.

The connector device according to the present embodiment includes a plug connector and a receptacle connector 400.

The plug connector may be the plug connector described in any of the above embodiments, and therefore, will not be described herein.

The receptacle connector 400 can be inserted therein by a plug connector. Both sides of the receptacle connector 400 may include holes 410 for mating with the snap-fit portions of the plug connector. The shape of the receptacle connector 400 is not limited to the shape shown in fig. 7, and may be any other suitable shape.

As one example, when the plug connector is inserted into the receptacle connector 400, the engagement portion of the locking portion of the plug connector enters the inside of the receptacle connector 400. When the movable portion of the control mechanism of the plug connector slides to the lock position (i.e., the position of the movable portion with respect to the base of the control mechanism when the lock portion of the plug connector does not elastically swing or hardly elastically swings) and the engagement portion engages with the hole 410, the plug connector cannot be pulled out of the receptacle connector. When the movable portion of the control mechanism slides away from the locking position, one end of the locking portion of the plug connector close to the engaging portion is pulled by the pulling portion of the control mechanism to elastically swing, and the engaging portion of the locking portion of the plug connector can be disengaged from the hole 410.

Thus, according to the connector device of embodiment 2, while ensuring a simple and reliable structure of the connector device, the connection state between the plug connector and the receptacle connector 400 can be easily controlled by adjusting only the sliding of the movable portion of the plug connector, thereby ensuring the connection between the plug connector and the receptacle connector 400 to be easy and saving the operation space.

Alternative embodiments of the present application are described in detail above. It will be appreciated that various embodiments and modifications may be made thereto without departing from the broader spirit and scope of the application. Many modifications and variations will be apparent to those of ordinary skill in the art in light of the teachings of this application without undue experimentation. As a non-limiting example, one skilled in the art may omit one or more of the various components of the above-described system or structure, add one or more components to the above-described system or structure, or replace some or all of the various structures or systems involved in the present embodiment with other components having the same or similar functions. Therefore, the technical solutions available to those skilled in the art through logic analysis, reasoning and limited experiments based on the concepts of the present application shall fall within the scope of protection defined by the claims of the present application.

It should be noted that while this disclosure includes several embodiments, these embodiments are non-limiting (whether or not they are labeled as exemplary), and that there are alterations, permutations, and equivalents, which fall within the scope of this invention.
