However, since the inside of the incoming wire end is usually a flat structure, when the wire head of the connecting wire enters the inside of the incoming wire end, one hand of the worker needs to continuously press the entering wire head so that the wire head does not fall off from the inside of the incoming wire end, and the other hand uses the pressing tool to press the incoming wire end, so that the process of installing the spring-loaded terminal on the connecting wire is relatively inconvenient.

[0027] Therefore, in order to solve the problem that the existing spring-loaded terminal lacks a pre-locking structure for the wire head, the worker needs to manually press the wire head before clamping the incoming wire end, which is low in convenience, and to realize the function of improving the installation efficiency of the spring-loaded terminal and the connecting wire, the utility model discloses a loudspeaker connecting wire lock, which is Figure 1 and Figure 2 , comprising a male end 1 and an incoming wire end 3 arranged in an array, wherein the male end 1 is used for externally connecting a male plug plate, the incoming wire end 3 is used for externally connecting a connecting wire, specifically, further comprising a wire tail fixing groove 6, the wire tail fixing groove 6 is arranged at one end of the incoming wire end 3 away from the male end 1, a wire head fixing groove 8, the wire head fixing groove 8 is arranged at one end of the incoming wire end 3 towards the male end 1, a pre-locking assembly 9 is arranged between the wire tail fixing groove 6 and the wire head fixing groove 8, the pre-locking assembly 9 comprises a wire passing layer 10 and a pressing column 12, the top of the wire passing layer 10 is provided with an insertion groove 15, the pressing column 12 is arranged in the insertion groove 15 in a lifting manner, wherein one end of the pressing column 12 arranged in the insertion groove 15 is provided with a second pressing plate 11.

[0028] In the embodiment, when the worker inserts the connecting wire into the wire inlet end 3, the user can pass the wire head of the connecting wire through the wire passing layer 10, and then the wire head can extend into the wire head fixing groove 8 through the wire passing layer 10, at this time the wire tail is blocked in the wire tail fixing groove 6 by the wire passing layer 10, and then the worker can press the pressing column 12, so that the second pressing plate 11 is pressed on the connecting wire inside the wire passing layer 10 under the driving of the pressing column 12, so that the connecting wire can be clamped inside the wire inlet end 3, so that the worker does not need to continuously press the entering connecting wire after inserting the connecting wire into the wire inlet end 3, and directly uses a wire pressing tool to complete the clamping of the connecting wire.

[0029] It should be noted that the wire head refers to the exposed copper wire part of the connecting wire, and the wire tail refers to the part of the connecting wire wrapped with a rubber sleeve. In the above embodiment, the opening of the wire passing layer 10 is an elongated strip structure, so as to facilitate the worker to splice or separate the wires, and at the same time, the rubber sleeve can be blocked outside the opening.

[0030] At the same time, in order to facilitate the wire inlet end 3 to clamp the connecting wire, the two sides of the wire tail fixing groove 6 are provided with a first clamping plate 5, and the two sides of the wire head fixing groove 8 are provided with a second clamping plate 7, wherein the first clamping plate 5 and the second clamping plate 7 are protruded on the top of the wire inlet end 3, through the above structure, the worker can bend the first clamping plate 5 and the second clamping plate 7 respectively by using a pressing tool, so that the wire tail and the wire head of the connecting wire can be clamped and fixed respectively.

[0031] Further, after clamping the connecting wire inside the wire inlet end 3, the worker can connect the male end 1 with the male plug plate on the horn terminal, so as to fix the connecting wire on the horn terminal, and specifically further comprising a first pressing plate 2, wherein two first pressing plates 2 are arranged in parallel on the two sides of the top of the male end 1, and the first pressing plate 2 is in contact with the top of the external male plug plate, through the arrangement of the first pressing plate 2, the male end 1 can clamp the male plug plate, so as to improve the connection tightness between the male end 1 and the male plug plate.

[0032] For example, when the male end 1 is connected with the male plug plate, a gap is arranged between the opposite side of the two first pressing plates 2 and the top of the male end 1, the worker inserts the male plug plate into the gap between the top of the male end 1 and the first pressing plate 2, and then presses the first pressing plate 2 by using a pressing tool, so that the first pressing plate 2 can be bent towards the male plug plate, so as to complete the fixation of the male plug plate.

[0033] It is worth mentioning that the first pressing plate 2 is arranged in a semicircular structure, and the first pressing plate 2 extends along the length direction of the male end 1, in this way, the semicircular structure not only increases the contact area with the male plug, but also enables the first pressing plate 2 to apply pressure more uniformly during the pressing process, thereby further improving the clamping stability with the male plug.

[0034] In addition, when the male plug is inserted into the male end 1 and the connecting wire passes through the wire inlet end 3, the wire head of the male plug and the connecting wire will extend to the butt joint groove 4, and the butt joint groove 4 is arranged between the wire head fixing groove 8 and the male end 1.

[0035] Embodiment two

[0036] On the basis of the first embodiment, in order to enable the second pressing plate 11 to stably clamp the connecting wire, referring to Figure 2 and Figure 3 The utility model also includes a pearl 16 for limiting the pressing block 12, specifically, a blind groove extending along the length direction of the wire passing layer 10 is arranged on the inner wall of the insertion groove 15, a pearl 16 is arranged at the opening of the blind groove, and a spring 17 is arranged between the pearl 16 and the inner wall of the blind groove, and a perforation 18 matched with the pearl 16 is arranged on the side wall of the pressing column 12.

[0037] In the embodiment, when the wire head of the connecting wire passes through the wire passing layer 10 and reaches the wire head fixing groove 8, the staff can press the pressing block 12, so that the pressing block 12 slides along the length direction of the insertion groove 15 towards the bottom of the wire passing layer 10 until the bottom of the pressing block 12 is in close contact with the surface of the connecting wire, at this time, the perforation 18 on the side wall of the pressing block 12 moves to the position corresponding to the pearl 16 on the inner wall of the insertion groove 15, and due to the action of the spring 17 between the pearl 16 and the inner wall of the blind groove, the pearl 16 is popped out and embedded into the perforation 18, thereby limiting and fixing the pressing block 12.

[0038] Meanwhile, when it is necessary to release the fixing of the connecting wire, the staff only needs to pull up the pressing column 12 to move the second pressing plate 11 upwards, thereby facilitating the reuse of the loudspeaker connecting wire lock catch.

[0039] Through the above structure, the second pressing plate 11 can maintain a stable clamping state after pressing the connecting wire, and will not be loosened due to slight touching of external force, and secondly, the staff does not need to use external tools when pre-locking or releasing the locking of the connecting wire, and only needs to press or lift the pressing column 12.

[0040] In this embodiment, in order to avoid the path deviation of the second pressing plate 14 when it is lifted in the threading layer 10, the two ends of the second pressing plate 11 are provided with guide blocks 14, and the two sides of the threading layer 10 are provided with guide grooves 13 extending along the height direction of the threading layer 10, wherein the guide blocks 14 are movably arranged in the guide grooves 13. Through this arrangement, the guide grooves 13 can limit the lifting path of the second pressing plate 14, so that the second pressing plate 14 is not easy to deviate in the left and right directions, thereby improving the stability of the second pressing plate 14 during lifting.

[0041] In summary, in combination with Embodiment One and Embodiment Two, the working steps of the loudspeaker connecting wire lock are as follows:

[0042] Firstly, the staff inserts the wire head of the connecting wire into the threading layer 10, ensures that the wire tail is fixed in the wire tail fixing groove 6, and the wire head extends to the wire head fixing groove 8. Then, the staff presses the pressing column 12, which descends in the insertion groove 15, and drives the second pressing plate 11 to tightly adhere to the connecting wire, realizing the preliminary pre-locking. At this time, due to the arrangement of the bump bead 16 and the perforation 18, the pressing column 12 can be clamped in the current position in the insertion groove 15, so that the clamping of the second pressing plate 11 to the connecting wire is stable and reliable.

[0043] Subsequently, the staff can use the pressing tool to bend the first and second clamping plates 5 and 7, so that the wire tail and the wire head of the connecting wire are firmly clamped in the wire tail fixing groove 6 and the wire head fixing groove 8, respectively, in order to improve the connection strength between the connecting wire and the wire inlet end 3.

[0044] Subsequently, the staff connects the male end 1 with the male plug plate on the loudspeaker terminal. During the connection process, the first pressing plate 2 is bent by using the pressing tool, so that it tightly contacts with the top of the male plug plate, thereby realizing the firm clamping of the male plug plate.

[0045] Finally, when the male plug plate is completely inserted into the male end 1, and the connecting wire is stably fixed in the wire inlet end 3, the wire head of the connecting wire and the male plug plate are located on the butt joint groove 4, which is used for subsequent electrical connection or signal transmission.

[0046] It is worth mentioning that the loudspeaker connecting wire lock is provided with the pre-locking assembly 9, so that the staff does not need to continuously press after inserting the connecting wire, which improves the installation efficiency of the connecting wire. At the same time, the limiting structure of the bump bead 16 and the perforation 18 and the guide structure of the guide block 14 and the guide groove 13 jointly ensure the stability and accuracy of the second pressing plate 11 during lifting, thereby further improving the reliability and durability of the entire lock.

[0047] The various embodiments in the specification are described in a progressive manner, and each embodiment focuses on the difference from other embodiments. The same or similar parts of each embodiment can be referred to each other.
