Description

Technical Field

[0001] The utility model relates to the technical field of connector pins, in particular to a connector pin production raw material presetting rack. Background Art

[0002] A pin is a component of a plug connector. A pin is a metal rod that is usually attached to the end of a wire or cable. The pin can be inserted into a socket to establish a circuit connection.

[0003] The raw material for the production of pin connectors is copper rods. The copper rods become thinner after being stretched. The thinned copper rods are then used to make pins. The copper rods as raw materials need to be prepared in advance on the side of the conveying trough of the pin equipment through a pre-setting rack. After the copper rods in the conveying trough are used up, the copper rods prepared in the pre-setting rack are quickly fed into the conveying trough to complete the replacement of the copper rods. The currently used copper rod pre-setting rack is an arc-shaped design with an upper opening. When the copper rod is moved out, the copper rod needs to be lifted upward. The lifted copper rod will be deformed to a certain extent, which will cause the conveying trough to slip when the copper rod is subsequently fed into the stretching assembly, resulting in a phenomenon of poor fit, and then slipping, which affects the normal delivery of the subsequent copper rods. For this reason, we propose a connector pin production raw material pre-setting rack. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a connector pin production raw material pre-setting rack, which solves the problem that the currently used copper rod pre-setting rack needs to lift the copper rod upward when moving the copper rod out, and the lifted copper rod will be deformed to a certain extent, causing the conveying trough to slip when subsequently feeding the copper rod into the stretching assembly, thereby affecting the subsequent normal conveying of the copper rod.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a connector pin production raw material presetting rack, comprising a presetting rack body, the interior of the presetting rack body is formed with a copper rod guide placement interval, the end of the copper rod guide placement interval is formed with an end transition section, the end of the end transition section is provided with a plurality of groups of guide slots, each group of guide slots is sleeved with a guide rod, the lower end of the guide rod is sleeved with a spring, and the upper ends of the guide rods are connected with a copper rod release limiting plate;

[0006] The guide rod and spring cooperate with the copper rod release limiting plate to form a side structure with adjustable upper and lower heights. The side structure cooperates with the copper rod guide placement interval to form a raw copper rod placement area. The side structure releases the copper rods in the placement area one by one by adjusting its own height.

[0007] Preferably, the copper rod guide placement section is designed to be a continuous arc, and the continuous arc of the copper rod guide placement section falls unilaterally toward one side of the pre-mounting rack body.

[0008] Preferably, the end transition section is designed to be horizontal, and a gap difference is left between the end transition section and the end of the copper rod guide placement interval. The end transition section forms an area for accommodating the copper rod release limiting plate through the gap difference between the end transition section and the copper rod guide placement interval.

[0009] Preferably, the end of the copper rod release limiting plate is designed to be arc-shaped, and the arc-shaped part of the side of the copper rod release limiting plate is flush with the bottom side of the copper rod guide placement interval.

[0010] Preferably, the outer wall of the guide rod is in contact with the bottom side wall of the copper rod guide placement area.

[0011] Preferably, an auxiliary fixing device is provided at the bottom of the pre-mounted frame body, and the auxiliary fixing device fixes the pre-mounted frame body to the side of the material feeding end of the external production equipment.

[0012] Preferably, the auxiliary fixing device includes a connecting base, a positioning groove, a fixed connecting plate, a threaded hole and a fixing knob, the connecting base is arranged at the bottom of the pre-set frame body, the positioning groove is opened at the top of the pre-set frame body, the fixed connecting plate is sleeved in the positioning groove, the threaded hole is opened at a position corresponding to the bottom of the pre-set frame body and the positioning groove, and the fixing knob is threadedly connected in the threaded hole.

[0013] Preferably, the fixed connecting plate is fitted with the top of the inner wall of the pre-mounted frame body, and the end of the fixed knob is ground to match the fixed connecting plate.

[0014] Compared with the prior art, the utility model can achieve the following beneficial effects:

[0015] 1. By setting the guide rod and the spring, the copper rod release limiting plate is used to form a side structure with adjustable height up and down. The copper rod guide placement interval in the side structure forms a raw copper rod placement area. The side structure releases the copper rods in the placement area one by one by adjusting its own height. There is no need to take out the copper rods, so as to avoid deformation of the copper rods when picking them up.

[0016] 2. The end of the copper rod release limiting plate is designed to be arc-shaped. The arc-shaped design can form a smooth upward sliding obstruction space between the copper rod release limiting plate and the copper rod guide placement area. When the copper rod release limiting plate is lowered to the same height as the copper rod along with the guide rod, the copper rod will not immediately slide along the surface of the copper rod release limiting plate. When the copper rod release limiting plate further drops below the height of the copper rod, the copper rod can slide down under the operator's fluctuations. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to make the technical means, creative features, purpose and efficacy of the utility model easy to understand, the utility model is further described below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the utility model, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the utility model. The experimental methods in the following embodiments are all conventional methods unless otherwise specified, and the materials, reagents, etc. used in the following embodiments are all commercially available unless otherwise specified.

[0023] Example:

[0024] See also Figure 1 - Figure 4 A connector pin production raw material presetting rack, comprising a presetting rack body 1, a copper rod guide placement interval 2 is formed inside the presetting rack body 1, an end transition section 3 is formed at the end of the copper rod guide placement interval 2, a plurality of groups of guide slots 4 are opened inside the end transition section 3, a guide rod 5 is sleeved inside each group of guide slots 4, a spring 6 is sleeved at the lower end of the guide rod 5, and a copper rod release limiting plate 7 is connected between the upper ends of the guide rods 5;

[0025] The guide rod 5 and the spring 6 cooperate with the copper rod release limiting plate 7 to form a side structure with adjustable upper and lower heights. The side structure releases the copper rods in the placement area one by one by adjusting its own height. There is no need to take out the copper rods, thereby avoiding deformation of the copper rods when picking them up.

[0026] The copper rod guide placement interval 2 is designed in a continuous arc shape, and the continuous arc of the copper rod guide placement interval 2 falls unilaterally toward one side of the pre-set frame body 1. The copper rods placed inside the copper rod guide placement interval 2 have a tendency to slide down along one side of the copper rod guide placement interval 2, which is convenient for releasing the copper rods one by one.

[0027] The end transition section 3 is designed to be horizontal, and there is a gap difference between the end transition section 3 and the end of the copper rod guide placement interval 2. The end transition section 3 forms an area for accommodating the copper rod release limiting plate 7 through the gap difference between the end transition section 3 and the copper rod guide placement interval 2. When the copper rod release limiting plate 7 is completely retracted into the end transition section 3 along with the guide rod 5, it can ensure that the copper rod in the internal space of the copper rod guide placement interval 2 can slide out normally.

[0028] The end of the copper rod releasing limiting plate 7 is designed to be arc-shaped, and the arc-shaped part of the side of the copper rod releasing limiting plate 7 is flush with the bottom side of the copper rod guiding and placing section 2. The arc-shaped design can form a smooth upward sliding obstruction space between the copper rod releasing limiting plate 7 and the copper rod guiding and placing section 2. When the copper rod releasing limiting plate 7 is lowered to a height flush with the copper rod along with the guide rod 5, the copper rod will not immediately slide along the surface of the copper rod releasing limiting plate 7. When the copper rod releasing limiting plate 7 further drops below the height of the copper rod, the copper rod can slide down under the fluctuation of the operator.

[0029] The outer wall of the guide rod 5 fits with the bottom side wall of the copper rod guide placement interval 2, thereby avoiding the formation of a space for the copper rod to be stuck between the guide rod 5 and the copper rod guide placement interval 2. At the same time, the copper rod release limiting plate 7 fixed to the end of the guide rod 5 can enter the end transition section 3 without hindrance along with the guide rod 5, thereby ensuring the unimpeded release of the copper rod in the bottom space of the copper rod guide placement interval 2.

[0030] An auxiliary fixing device is provided at the bottom of the pre-set frame body 1, and the auxiliary fixing device fixes the pre-set frame body 1 to the side of the feeding end of the external production equipment. The auxiliary fixing device includes a connecting base 8, a positioning groove 9, a fixed connecting plate 10, a threaded hole 11 and a fixed knob 12. The connecting base 8 is arranged at the bottom of the pre-set frame body 1, the positioning groove 9 is opened at the top of the pre-set frame body 1, the fixed connecting plate 10 is sleeved in the positioning groove 9, and the threaded hole 11 is opened at the position corresponding to the bottom of the pre-set frame body 1 and the positioning groove 9. The threaded hole 11 is threadedly connected with a fixing knob 12. When in use, a section of the fixed connecting plate 10 is fixed to the side of the external conveying trough. After the fixed connecting plate 10 is fixed, the relative position of the pre-set frame body 1 and the conveying trough is adjusted by the mutual cooperation between the positioning groove 9 and the fixed connecting plate 10. When the side of the pre-set frame body 1 is flush with the side of the conveying trough, the fixing knob 12 is rotated so that the fixing knob 12 completes the fixing of the relative position of the pre-set frame body 1 and the fixed connecting plate 10 by contacting the fixed connecting plate 10.

[0031] The fixed connecting plate 10 is fitted with the top of the inner wall of the pre-mounted frame body 1, and no step difference is formed between the fixed connecting plate 10 and the pre-mounted frame body 1, so that the fixed connecting plate 10 and the pre-mounted frame body 1 maintain a relatively stable setting state. The end of the fixed knob 12 is ground to match the fixed connecting plate 10. After the end of the fixed knob 12 is in conflict with the fixed connecting plate 10 through a threaded connection, it plays a role in limiting the position of the fixed connecting plate 10 relative to the pre-mounted frame body 1, thereby ensuring the stability of the connection between the two.

[0032] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
