However, this locking structure increases the connector's dimensions in the height direction, making it unusable in some height-limited applications and affecting the application of the equipment. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, this utility model designs a new locking structure for the connector, and an anti-sparking electrical connector with the locking structure.

[0004] The technical solution of this utility model is as follows:

[0005] A locking structure for a connector includes a first housing and a second housing suitable for mating. The locking structure is characterized by having a locking mechanism at least at one end of the first and second housings along their length. The locking mechanism includes a locking block disposed on the first housing along its width, and a guide rail disposed on the second housing along its width. A slider is disposed on the guide rail, and the slider has a second slot. When the slider slides to one end of the guide rail, the second slot separates from the locking block, and the locking structure is in an unlocked state. When the slider slides to the other end of the guide rail, the locking block engages within the second slot, and the locking structure is in a locked state.

[0006] Furthermore, a locking boss is provided at the end of the side wall of the locking block away from the guide rail. When the locking structure is in the locked state, the locking boss is used to prevent the slider from moving to the other end of the guide rail.

[0007] Furthermore, a strip block is provided on one side of the upper surface of the guide rail along its length.

[0008] Furthermore, the end of the strip block near the unlocked state is provided with a transition slope that connects to the upper surface of the guide rail.

[0009] Furthermore, the upper surface of the locking block is provided with a first limiting boss, which is used to limit the distance the slider slides from the unlocked state to the locked state.

[0010] Furthermore, the guide rail is provided with a second limiting boss at the end away from the locking block, and the second limiting boss is used to restrict the slider from slipping off the guide rail.

[0011] Furthermore, the guide rail is a dovetail guide rail, and the slider is provided with a dovetail groove that mates with the guide rail.

[0012] Furthermore, the upper surface of the slider is provided with several ribs along its length.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0027] It should be noted that when a component is referred to as being "set on" or "fixed to" another component, it can be directly on the other component or there may be an intermediate component. When a component is referred to as being "fixed to" another component, or "fixedly connected" to another component, the fixing method can be detachable or non-detachable. When a component is considered to be "connected" or "rotatably connected" to another component, it can be directly connected to the other component or there may be an intermediate component. The terms "vertical," "horizontal," "left," "right," "upper," "lower," and similar expressions used are for illustrative purposes only and do not represent the only possible implementation.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] In this invention, terms such as "first," "second," and "third" are used not to represent specific quantities or orders, but merely to distinguish names.

[0030] The length and width directions are defined here; see [link to relevant documentation]. Figure 5 As shown, Figure 5 This is a frontal view of the tail of the first shell; the longer side of the first shell in the figure represents the length direction, and the shorter side of the first shell in the figure represents the width direction.

[0031] See Figure 1 As shown, the connector's locking structure includes a first housing 1 and a second housing 2 suitable for insertion and mating. A locking structure 3 is provided at least at one end of the length direction of the first housing 1 and the second housing 2. In this embodiment, locking structures are provided at both ends of the length direction of the first housing and the second housing, thus improving the locking effect. The locking structure 3 includes a locking block 30 provided on the first housing 1 along its width direction, and a guide rail 31 provided on the second housing along its width direction. A slider 32 is provided on the guide rail 31, and a second slot 320 is provided on the slider 32. When the slider 32 slides to one end of the guide rail 31, the second slot 320 separates from the locking block 30, and the locking structure is in an unlocked state. When the slider 32 slides to the other end of the guide rail 31, the locking block engages within the second slot, and the locking structure is in a locked state.

[0032] This invention designs a novel locking structure. A slider moves on a guide rail. When the slider is at one end of the guide rail, there is no engagement between the locking block and the second slot, thus no locking is formed. At this time, the first and second housings can be separated. When the slider slides to the other end of the guide rail, the locking block engages with the second slot. At this point, the slider connects the guide rail and the locking block, forming a locking relationship along the insertion direction. The first and second housings cannot be separated, thus achieving locking. Furthermore, the locking structure is located at the ends of the first and second housings along their length, without increasing the connector's thickness, meeting the connector's usage requirements in certain scenarios.

[0033] See Figure 2 As shown, a locking boss 301 is provided at the end of the side wall of the locking block 30 away from the guide rail. When the locking structure is in the locked state, the locking boss 301 is used to prevent the slider from moving to the other end of the guide rail. There is a certain amount of interference between the locking boss and the second groove. When the locking structure is in the locked state, the locking boss can prevent the slider from coming off the locking block, thus improving the reliability of the locking. The locking structure remains reliable in some vibration environments.

[0034] like Figure 2 As shown, a strip block 310 is provided on one side of the upper surface of the guide rail 31 along the length direction. Both ends of the strip block 310 are provided with transition slopes 311 that connect to the upper surface of the guide rail. The transition slopes serve as a guide, making it easier for the slider to slide onto the upper surface of the strip block. Combined with the fact that the guide rail is a dovetail guide rail and the slider is provided with a dovetail groove that cooperates with the guide rail, when the slider rises along the transition slope of the strip block, the pressure between the side of the dovetail groove of the slider and the dovetail guide rail is increased, thereby increasing the static friction between the two, which is beneficial to the locking reliability of the locking structure and makes it less likely to loosen.

[0035] Alternatively, the strip blocks of the guide rail may not have transition slopes at either end, or the ends of the strip blocks near the unlocked state may have transition slopes that connect to the upper surface of the guide rail. The transition slopes are mainly used to reduce resistance when pushing the slider in the initial stage, making it easier for users to use.

[0036] See Figure 3 As shown, the upper surface of the locking block 30 is provided with a first limiting boss 302. The first limiting boss is used to limit the distance that the slider slides from the unlocked state to the locked state. The first limiting boss is located at one end of the upper surface of the locking block, specifically at the end away from the locking boss. If the slider slides towards the first limiting boss, without the obstruction of the first limiting boss, the slider may easily move too far, which may pose a risk of slipping off the guide rail.

[0037] To elaborate further, see Figure 4 As shown, the guide rail 31 has a second limiting boss 312 at the end away from the locking block. The second limiting boss 312 is used to restrict the slider from sliding off the guide rail. When unlocking, the slider moves on the guide rail, and the second limiting boss is used to block the slider to prevent it from sliding off the guide rail.

[0038] Furthermore, the guide rail is a dovetail guide rail, and the slider is provided with a dovetail groove that mates with the guide rail.

[0039] The upper surface of the slider 32 is provided with a plurality of ribs 321 along the length direction. The ribs facilitate the user to apply force to the slider and make it easier for the user to operate. Preferably, the surface of the slider is provided with three ribs, the middle rib being larger than the two side ribs, and the cross-section of the middle rib being triangular.

[0040] See Figure 1 As shown, the anti-sparking electrical connector includes a locking structure for the connector.

[0041] In summary, this utility model has the following beneficial effects:

[0042] This utility model designs a novel locking structure. The movement of the slider on the guide rail, through the cooperation of the second slot of the slider and the locking block, realizes the locking of the first shell and the second shell. Moreover, the locking structure is set at the ends of the first shell and the second shell in the length direction, which does not increase the thickness of the connector, thus meeting the usage requirements of the connector in some scenarios.

[0043] Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
