Abstract
well pump wire clamp specifically designed to mount well pump wire cable to drop pipe located in the well casing. The well pump wire clamp generally comprises a first clamping member and a second clamping member configured for interlocking around the outer surface of the drop pipe keeping the wire cable safe from breakage. The first clamp member includes a U-shaped groove wide enough for engaging the wire cable and the tongue teeth located on the tapered tongue when inserted into the head will then engage the ratchet arm. The inner circumferential clamp surface is slightly modified by including a wire pipe rib to the first clamp member and a pipe rib to the second clamp member formed longitudinally along the inner circumferential clamp surface. When the well pump wire clamp is in a clamped position, the inner circumferential clamp surface and both pipe rib in engage and prevent the separation or disengaging of the well pump wire clamp from any skewing action. The second clamp member is similar to the first clamp member wherein both members include an outer guard for the preventing excessive or abnormal drop pipe torqueing or twisting when the pump starts and stops.
Claims

A two piece well pump wire clamp for holding wires to the drop pipe and keeping the wiring strongly secure along the full drop of piping in the well casing comprising: a first clamping member and a second clamping member configured for interlocking around the outside diameter of the drop pipe to form a complete 360-degree seal securing the wire to the drop pipe; a pair of tapered tongues of the first member with a predetermined number of teeth for insertion into the second clamp member head to engage with the ratchet arms of the second member developing opposing forces against the ratchet arms to maintain the teeth in engagement when both members are interlocked; a U-shaped groove including a ribbed tip project outward from the U-shaped groove of the first member to accommodate one or more wires to be held securely by the well pump wire clamp.
2. (canceled)
3. The well pump wire clamp of claim 1, wherein the dual-locking mechanism includes a ratchet arm on both sides of the second member project radially toward its associated tongue teeth to prevent transverse disengagement of said teeth when the clamp is engaged.
4.

5. The well pump wire clamp of claim 1, wherein a pair of tongues on first members include a longitudinal guide rail to engage a groove disposed longitudinally in the adjacent head of second member when the well pump wire clamp is engaged.
6. The well pump wire clamp of claim 1, wherein both members include a protruding support element adapted to guard the wires in a substantially centered position.
7. The well pump wire clamp of claim 1, wherein an extension groove is built into the second member to move against the outside diameter of the drop pipe to form a seal that holds the second and first member closer together.

DESCRIPTION OF CERTAIN EMBODIMENT OF THE PRESENT INVENTION
[0026] In the following detailed description of the preferred embodiment, reference is made to the accompanying drawings, which form a part of this application. The drawings show, by way of illustration, specific embodiments in which the invention may be practiced. It is to be understood that other embodiments may be utilized and structural changes may be made without departing from the scope of the present invention. assembly.
[0027] The present invention shown in FIG. 1 illustrate the well pump wire clamp 10 specifically designed to mount well pump wire cable 14 to drop pipe 13 located in the well casing (not shown). The well pump wire clamp generally comprises a first clamping member 11 and a second clamping member 12 configured for interlocking around the outer surface of the drop pipe 13 keeping the wire cable 14 safe from breakage.
[0028] As shown in FIG. 2, is a front view of the well pump wire clamp 10 comprises a first clamp member 11 and a second clamp member 12 together in a closed position about a drop pipe 13 and the wire cable 14 engaging the interlocking mechanism 16 by way of the tapered tongue 17 and the second clamp member head 15.
[0029] More specifically, as shown in FIG. 3, a front view of the well pump wire clamp 10 showing first clamp member and a second clamp member 11, 12 respectively, located around the drop pipe 13 and wire cable 14 in the open position before engaging the interlocking mechanism 16. The first clamp member 11 includes a U-shaped groove 20 wide enough for engaging the wire cable 14 and the tongue teeth 18 located on the tapered tongue 17 when inserted into the head 15 will then engage the ratchet arm 28.
