[0009] By arranging the positioning seats of different specifications in a staggered manner, the error generated after the cooling of the male plug and the female plug is shared. Generally, the error of the large-specification male plug insertion block or the positioning seat is smaller than that of the medium-specification male plug insertion block or the positioning seat, and the error of the medium-specification male plug insertion block or the positioning seat is smaller than that of the small-specification male plug insertion block or the positioning seat.

[0032] The following will be described in detail in combination with the accompanying Figure 1 - the Figure 3 , the present application will be further described in detail.
[0033] A pin connector, referring to Figure 1 , comprising a male plug and a female plug, the female plug comprising a glue shell 1, the glue shell 1 being provided with a mounting groove 12 on one side for inserting the male plug. The glue shell 1 is fixedly connected with a plurality of elbow pins 2, one end of the elbow pin 2 penetrating through the side wall of the glue shell 1 and being located in the mounting groove 12, and the other end being located outside the glue shell 1 and being parallel to the penetrated side wall of the glue shell 1.
[0034] Referring to Figure 1 The inner wall of the mounting groove 12 is integrally connected with five positioning seats 3, the side of the positioning seats 3 facing the groove bottom of the mounting groove 12 is integrally connected with the groove bottom of the mounting groove 12, and the side of the positioning seats 3 away from the groove bottom of the mounting groove 12 is coplanar with the side wall of the rubber shell 1.
[0035] The five positioning seats 3 are specifically large, medium and small specifications, two large specification and medium specification positioning seats 3 are provided, and one small specification positioning seat 3 is provided. The small specification positioning seat 3 is arranged at the middle of the inner wall of the mounting groove 12, two large specification positioning seats 3 are symmetrically arranged on both sides of the small specification positioning seat 3, and two medium specification positioning seats 3 are symmetrically arranged on the side away from each other of the two large specification positioning seats 3. Gaps are left between adjacent positioning seats 3 as limiting grooves 11, and the male plug is provided with limiting blocks matched with the limiting grooves 11.
[0036] The two medium specification positioning seats 3 are integrally connected with positioning strips 6 arranged on the side wall of the positioning seat 3 facing the elbow pin 2.
[0037] Sliding grooves 7 are formed on the two limiting grooves 11 between the small specification positioning seat 3 and the large specification positioning seat 3, the sliding grooves 7 are formed with openings on the side wall of the rubber shell 1 away from the groove bottom of the mounting groove 12, and the side of the sliding groove 7 away from the small specification positioning seat 3 is communicated with the large specification positioning seat 3.
[0038] The inner wall of the sliding groove 7 is inclined to form a limiting sliding slope 9, and the limiting sliding slope 9 is smoothly transitioned with the limiting groove 11 at the corresponding position. The side of the two limiting grooves 11 away from the groove bottom of the mounting groove 12 is inclined to form an insertion sliding slope 8, and the insertion sliding slope 8 is smoothly transitioned with the opening of the mounting groove 12.
[0039] Referring to Figure 2 , Figure 3 The rubber shell 1 is provided with a plurality of positioning grooves 4 on the side wall where the opening of the mounting groove 12 is located, the plurality of positioning grooves 4 are communicated with the mounting groove 12, and the plurality of positioning grooves 4 are located on the opposite inner walls of the mounting groove 12 where the positioning seats 3 are located.
[0040] The groove bottom of the positioning groove 4 is inclined to form a stable sliding slope 10, one end of the stable sliding slope 10 is fixedly connected with the rubber shell 1 on the side of the positioning groove 4 away from the positioning seat 3, and the other end of the stable sliding slope 10 extends obliquely towards the elbow pin 2, and is fixedly connected with the rubber shell 1 on the side opposite to the positioning seat 3.
[0041] Referring to Figure 1 , Figure 2 The inner side wall of the mounting groove 12 is fixedly connected with a guide strip 5, and the guide strip 5 extends from the opening of the mounting groove 12 towards the elbow pin 2.
[0042] The implementation principle of the embodiment of the present application is that when the connector is connected to the corresponding male plug, the insertion ramp 8 allows the male plug to be conveniently inserted into the rubber shell 1. The male plug slides on the five positioning seats 3 of different specifications. Since the positioning seats 3 are staggered and of different specifications, the male plug needs to be matched with the positioning seats 3 one by one when being inserted, so that the male plug can be accurately inserted into the mounting groove 12 of the connector.
[0043] At the same time, the male plug extends into the positioning groove 4, and the six guide strips 5 extend into the male plug and cooperate with the positioning seats 3 and the positioning groove 4 to simultaneously position and limit the four side surfaces of the male plug when the male plug is inserted into the rubber shell 1, so that the male plug does not deviate or misalign when being inserted.
[0044] After the male plug is inserted into the mounting groove 12, the male plug simultaneously slides on the positioning seats 3, the limiting grooves 11, the positioning groove 4, and the guide strips 5, and the insertion block of the male plug slides on the positioning seats 3. In the related art, the male plug and the female plug are generally integrally injection molded by a mold, and during the injection cooling process, the plastic rubber shell will shrink due to cooling, thereby causing errors and resulting in gaps when being connected.
[0045] In the present application, the errors caused by the cooling of the male plug and the female plug are shared by the staggered and different specifications of the positioning seats 3. Generally, the error of the large-specification insertion block or the positioning seat 3 is smaller than that of the medium-specification insertion block or the positioning seat 3, and the error of the medium-specification insertion block or the positioning seat 3 is smaller than that of the small-specification insertion block or the positioning seat 3. The large-specification insertion block with a small gap is matched with the positioning seat 3 to position the small-specification insertion block with a large gap, so as to improve the accuracy of the insertion of the male plug, and the positioning strip 6 further stabilizes the insertion block of the male plug.
[0046] In addition, the upper end surface of the male plug slides in the positioning groove 4, and the close arrangement of the positioning groove 4 reduces the shaking of the upper end surface of the male plug when sliding. At the same time, the two guide strips 5 arranged on the same surface as the positioning groove 4 are arranged between two adjacent positioning grooves 4, further stabilizing the upper end surface of the male plug.
[0047] When the connection end of the male plug is about to be connected to the elbow pin 2, the upper end surface of the male plug slides along the stable ramp 10. The relative distance between the upper end surface of the male plug and the rubber shell 1 is reduced, so that the upper end surface of the male plug abuts against the rubber shell 1. At the same time, the lower end surface of the male plug slides on the sliding groove 7, so that the lower end surface of the male plug abuts against the limiting ramp 9. This increases the friction between the male plug and the rubber shell 1, so that the male plug can be firmly connected to the female plug.
[0048] At the same time, since the male plug abuts against the rubber shell 1 and the friction therebetween is large, the male plug can be prevented from falling off the connector as much as possible when being used.
[0049] The connecting end of the male plug is inserted into the elbow pin 2, and the male plug slides along the limiting landslide 9. Because the limiting landslide 9 is in the shape of "L", the male plug is tightly attached to the limiting landslide 9 after sliding along the limiting landslide 9, so that the lower end surface of the male plug cannot continue to slide, and the male plug connecting end is prevented from being excessively inserted into the elbow pin 2, thereby preventing the elbow pin 2 from being damaged.
[0050] The embodiments of the present specific embodiment are the preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, wherein the same parts are denoted by the same reference numerals. Therefore, any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
